Pizza by the Slice: How to Sell More with Forza STi

Selling pizza by the slice allows pizzerias, bakeries, cafés, convenience stores and other foodservice businesses to serve customers who want hot pizza without ordering an entire pie.

Individual portions suit quick lunches, afternoon snacks, takeaway and grab-and-go meals, while giving operators another way to use their existing pizza production.

The concept can work with whole pizzas divided into portions, partially baked pizzas finished when ordered or individual slices cut from previously baked or partially baked pizzas. Whole pizzas can also be prepared from raw dough, depending on the production method.

The choice depends on customer traffic, preparation capacity and the type of service offered.

With the Prática Forza STi pizza oven, operators can combine these methods with programmable cooking, controlled hot-air circulation and rapid finishing.

This makes it possible to sell whole pizzas and individual slices from the same operation without relying on prolonged display of ready-to-eat products.

What Is Pizza by the Slice?

Pizza by the slice is a sales format in which customers purchase individual portions instead of an entire pizza.

It is common in takeaway outlets, street food businesses and pizzerias where customers want a quick meal or the freedom to combine different flavours.

Several pizza styles are suitable for this format. Italian pizza al taglio is generally prepared in rectangular trays and divided into portions, sometimes sold by weight.

Pizza in teglia also uses tray baking, making it suitable for batch production and consistent portioning.

New York-style pizza, meanwhile, is commonly prepared as a large round pizza and served in triangular slices.

These formats differ in dough thickness, shape and presentation, but they share the same commercial principle: customers can buy the quantity they want, whether that means a single slice or several portions.

Why Sell Pizza by the Slice Instead of Whole Pizzas?

Customers do not always need an entire pizza.

Someone on a short lunch break may prefer one slice, while another customer may want to try two flavours without ordering separate pizzas. Individual portions make pizza accessible for these different purchasing occasions.

For established pizzerias, slice sales can complement whole-pizza orders.

A production batch may include pizzas intended for sharing and others divided into portions for individual sale.

Bakeries and cafés can also add slices to their savoury selection without making pizza their main product.

The commercial benefits include:

• Flexible portion sizes for different appetites and budgets.
• Additional lunch, snack and evening sales opportunities.
• Faster service when preparation is organised in advance.
• Greater flavour variety without requiring customers to buy several whole pizzas.
• Meal combinations with beverages, salads and other products.
• Better use of production capacity when whole-pizza and slice sales share the same workflow.

These advantages depend on controlling portion costs, maintaining product quality and matching production to actual demand.

Four Ways to Prepare Pizza for Individual Slice Sales

There is no single production method suitable for every establishment. Businesses can choose between fully baked pizzas, partially baked pizzas and fresh whole-pizza preparation according to their sales volume and service routine.

For individual slice sales, the dough must be at least partially baked before the final finishing stage.

1. Bake Whole Pizzas and Sell Individual Slices

Whole pizzas can be baked, divided into portions and allocated to individual sales. This approach is especially relevant for pizzerias that already prepare pizzas throughout the day and want to offer smaller portions alongside their regular menu.

Fully baked slices can be reheated when ordered, allowing customers to receive hot pizza without waiting for another complete baking cycle. Appropriate storage and limited holding periods remain important for preserving quality.

2. Finish Partially Baked Pizza Bases

Partially baked bases allow operators to complete part of the preparation before service. The bases can be assembled with toppings and finished when customers order.

This method can be useful during concentrated periods of high demand because some of the preparation has already been completed. Final cooking must still be appropriate for the dough and toppings.

3. Finish Partially Baked Pizza Slices on Demand

Individual portions can be cut from partially baked pizzas and finished when customers order. This allows operators to prepare the dough in advance while completing the cooking process closer to service.

The Forza STi can finish suitable partially baked slices using validated programmes developed for their thickness, dimensions and toppings. Final cooking must be sufficient for the dough and ingredients.

4. Prepare Fresh Pizza in Front of Customers

A visible preparation counter allows customers to watch dough handling, topping selection and pizza assembly. This can attract attention in food courts, kiosks and other customer-facing locations.

Whole pizzas can be prepared from raw dough and baked according to the established production process. For individual slice sales, operators should use fully baked or partially baked pizzas, with reheating or final cooking performed when ordered.

The important consideration is organising the workflow so that visibility does not create unnecessary waiting times.

How the Forza STi Prepares Pizza Slices Quickly

The Prática Forza STi pizza oven uses high-speed impinged hot air and infrared heating. Unlike microwave-assisted speed ovens, the Forza STi relies on these heating technologies to bake pizzas and develop the required crust texture, surface colour and topping finish.

The oven provides independent control of air speed and upper and lower temperatures, with an operating range from 30°C to 330°C. It accommodates pizzas up to 40 cm in diameter and stores up to 1,024 recipes, each with as many as eight steps.

How Long Does It Take to Finish a Pizza Slice?

Application references supplied by the Prática team indicate approximately 15 seconds for reheating a suitable, fully baked slice, around 30 seconds for portions with lighter toppings and less than 45 seconds for slices with heavier toppings.

These times are specific application references, not universal cooking settings. Actual results depend on dough composition, slice dimensions, initial temperature, topping quantity and the validated programme. The oven must be properly preheated before service.

The reference times should not be interpreted as cooking times for raw pizza dough sold in individual slices. Partially baked portions require appropriate final cooking conditions established for the specific product.

How Does the Oven Maintain Crust Texture and Topping Quality?

Reheating pizza requires attention to the crust as well as the toppings. The base should retain its intended texture, while cheese and other ingredients reach the desired serving condition without unnecessary drying.

High-speed hot air transfers heat to the product surface, while infrared heating contributes to browning and finishing. Independent controls allow operators to adjust the process for thin-crust pizzas, thicker pan pizzas and different topping quantities.

Moist ingredients such as tomatoes, mushrooms and vegetables can release water during heating. Their effect on the final result depends on the formulation and cooking conditions, so programmes should be tested with the actual pizza rather than applying the same settings to every flavour.

Can Several Slices Be Cooked Together?

Yes. Multiple slices can be processed during the same cooking cycle when they fit within the usable cooking area and have compatible preparation requirements. Grouping portions with similar thicknesses and topping quantities helps maintain consistent results.

For example, lightly topped slices can be prepared separately from thicker portions with generous toppings.

This reduces differences between products and helps operators organise service during busy periods.

Programmable Recipes and Accessories

Once a suitable programme has been tested, operators can save it on the touchscreen for repeated use. Separate recipes can be created for different dough styles, flavours, topping quantities and preparation methods, helping employees reproduce established cooking conditions.

The Forza STi includes a Pizza Screen and Aluminum Paddle among its standard accessories. The Pizza Screen supports pizza preparation, while the paddle assists with loading and removal. Operators should use the accessories recommended for their products and follow the manufacturer's handling instructions.

How to Display Pizza Slices Without Losing Quality

A glass display counter helps customers recognise that individual slices are available. It can show different flavours, portion sizes and prices, particularly in bakeries, cafés and convenience stores where pizza is one of several food options.

Rectangular pizza al taglio portions and triangular slices can be arranged to make the selection easy to understand. Clear labels should identify flavours, prices and relevant allergen information.

However, the display should not become a place where prepared pizzas remain for unnecessarily long periods. Extended holding can affect crust texture, topping moisture and serving quality.

A more suitable approach is to use the counter for product presentation while organising preparation and final heating according to demand. Any food physically displayed for sale must be held under appropriate food safety conditions.

Storage, Reheating and Food Safety

Raw whole pizzas, partially baked pizzas and fully baked pizzas require different handling procedures. The same applies to refrigerated and frozen products, which must be stored and prepared according to their characteristics.

Fully baked slices can be reheated using a validated programme. Partially baked slices require completion of cooking before serving. Raw dough preparation remains an option for whole pizzas, but not for individual slices intended for rapid finishing and sale.

Refrigerated pizza generally requires less heating time than comparable frozen products, making it useful for operations prioritising rapid service. Frozen preparations offer another inventory option but require programmes suited to their initial temperature.

Foodservice businesses must follow applicable European and national food safety requirements, including HACCP-based procedures. These cover temperature control, cooling, storage, prevention of cross-contamination and validated cooking or reheating processes.

Rapid preparation times do not replace food safety verification. Operators must establish suitable conditions for each product before introducing it into regular service.

Pizza Slice Packaging for Takeaway and Grab-and-Go

Individual portions need packaging that is convenient to carry and suitable for hot food. Common options include cardboard slice boxes, foodservice trays and sleeves designed for pizza.

Large triangular slices may require longer packaging, while rectangular portions can fit into smaller cartons. Customers purchasing several flavours may prefer a box that keeps the slices organised and protects the toppings.

Packaging also affects texture. Hot pizza releases moisture, which can accumulate as condensation inside closed containers and soften the crust. Materials and designs should therefore be selected according to the product's temperature, shape and expected transport time.

For street food, transport hubs and other grab-and-go locations, packaging should make immediate consumption convenient without compromising food safety or presentation.

How to Organise Pizza Slice Production and Reduce Waste

Efficient slice sales depend on preparing quantities that reflect customer demand. A bakery may experience a concentrated lunchtime rush, while a convenience store may sell smaller quantities throughout the afternoon and evening.

Operators should monitor their most popular flavours, expected customer traffic and the number of unsold portions after each service period.

A straightforward workflow includes:

• Select pizza styles and flavours suitable for individual portions.
• Estimate demand and establish preparation quantities.
• Prepare whole pizzas, fully baked slices or partially baked portions according to the selected production method.
• Standardise portion dimensions and store products correctly.
• Present available flavours and prices at the counter.
• Finish portions when ordered using validated programmes.
• Review sales and adjust future production.

Finishing on demand can help avoid a common problem in slice-selling operations: fully baked pizzas remaining on display until their texture deteriorates. Slices that are served cold, reheated inadequately or held for too long may disappoint customers or eventually be discarded.

Preparing suitable quantities in advance and completing the final heating closer to service can help preserve quality and reduce waste. The result still depends on demand forecasting, correct storage and inventory control.

Continuous Operation During Busy Periods

The Forza STi is designed for professional foodservice use and supports repeated cooking cycles during busy periods. Programmable recipes allow employees to select established settings quickly, while grouping compatible portions helps organise oven loading.

Consistent service also depends on proper preheating, routine cleaning, correct accessory use and sufficient preparation capacity outside the oven.

Increase Pizza Slice Capacity with Two Stacked Forza STi Ovens

Businesses with high customer traffic can install two Forza STi ovens in a stacked configuration. This provides twice the installed oven processing capacity of one unit under equivalent operating conditions, while using a similar floor footprint.

Both ovens operate independently. One can prepare thin slices with lighter toppings while the other handles thicker portions or different recipes, reducing competition for the same cooking chamber.

This configuration can be particularly useful in busy pizzerias, shopping centres, transport hubs and high-volume takeaway operations.

Actual output per hour depends on cooking cycles, portion dimensions, loading patterns and the organisation of service. Stacked installation must follow the manufacturer's electrical, clearance and safety specifications.

Frequently Asked Questions About Pizza by the Slice

Can You Cook Partially Baked Pizza Slices in the Forza STi?

Yes. Individual portions cut from partially baked pizzas can be finished in the Forza STi using programmes developed for their thickness, toppings and dimensions. The dough must be at least partially baked before this finishing stage, and the cooking process must be validated for the actual product.

Can the Forza STi Bake Whole Pizzas from Raw Dough?

Yes. Whole pizzas can be prepared from raw dough using suitable programmes developed for the dough formulation, pizza dimensions and toppings. This production method is different from the rapid finishing of individual slices, which must already be partially or fully baked.

How Long Does It Take to Reheat a Pizza Slice?

Application references supplied by Prática indicate approximately 15 seconds for a suitable, fully baked slice. The actual time depends on the initial temperature, portion size and validated cooking programme.

Can You Use the Same Oven for Whole Pizzas and Slices?

Yes. The Forza STi accommodates whole pizzas up to 40 cm in diameter and can also prepare individual portions. This allows establishments to offer both sales formats using the same equipment.

Is Selling Pizza by the Slice Profitable?

It can be profitable when portion pricing, production costs, sales volume and waste are properly managed. Businesses should calculate the full cost of each portion and adjust production according to customer demand.

Start Selling Pizza by the Slice with Forza STi

Pizza by the slice allows businesses to offer smaller portions, different flavours and convenient takeaway meals without abandoning whole-pizza sales. Production can be organised around fully baked pizzas divided into slices or partially baked pizzas finished when ordered. Whole pizzas prepared from raw dough remain another option for establishments offering both sales formats.

The Forza STi supports these methods through controlled high-speed cooking, programmable recipes, compact electric installation and the option of two stacked ovens. Combined with appropriate storage, clear product presentation and finishing on demand, these features help operators serve hot pizza while maintaining consistent preparation conditions.
