Hosts planning buffet portions
If pizza will sit alongside other dishes, compare cooked kcal per 100g and decide how large each slice will be. NHS Better Health notes that a manufacturer’s portion may differ from the portion you serve.
Who is this for?
Hosts serving different dietary needs
Keep vegan, vegetarian or gluten-free pizzas identifiable, and check the delivered pack’s ingredients and allergen statements for each one. A dietary label alone does not establish suitability for a guest with an allergy.
Caterers and venues serving hot pizza
Plan oven capacity and replenishment as well as portions. Food Standards Agency and GOV.UK caterer guidance sets out hot-holding and timed-display controls for a hot buffet.
What should you check before buying?
Start with the portion guests will take, then check whether each pizza can be identified and served appropriately throughout the buffet.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Compare cooked kcal per 100g, the label’s serving size and kcal per serving. Decide how your planned slices relate to that serving. | I want to know what a guest’s slice represents, not just which pizza has a lower per-100g figure. NHS Better Health cautions that labelled portions may differ from portions served. |
| Dietary and allergen information | Read the exact pack’s dietary description, ingredients, allergen statement and any may-contain wording. Plan how to identify each variant at the buffet. | Guests need to be able to tell pizzas apart. ASDA Groceries lists wheat in Dr. Oetker Ristorante Vegan Margherita Pomodori and a possible milk presence; Tesco Groceries lists a wheat-trace warning for Goodfella's Gluten Free Margherita. |
| Cooking and display | Check each pack’s cooking instructions against oven capacity. For catered hot service, plan suitable hot holding or a timed display. | I need batches I can cook and serve as planned. Food Standards Agency and GOV.UK caterer guidance says hot food should be held at 63°C or above; where that is not possible, it permits display for up to two hours on one occasion. |
What can go wrong?
-
Equating lower kcal per 100g with a small portion
A per-100g comparison does not show the calories in a half pizza or a buffet slice. ASDA Groceries lists 221 kcal per 100g for Dr. Oetker Ristorante Vegan Margherita Pomodori, but 377 kcal for its labelled half pizza.
Choose a slice size before planning quantities, and compare it with the portion information on the current pack.
-
Assuming a dietary label answers every allergy question
The vegan Dr. Oetker pizza listed by ASDA Groceries contains wheat and may contain milk. Tesco Groceries says Goodfella's Gluten Free Margherita may contain traces of wheat.
Check the delivered packs, identify each pizza and its ingredients for guests, and use separate serving equipment where needed.
-
Treating a large loaded pizza as a lower-calorie option
Tesco Groceries lists Goodfella's New York Style Fully Loaded Pepperoni at 265 kcal per 100g and 705 kcal per labelled half pizza. Both figures matter when deciding how it fits the buffet.
If you include a loaded pizza, assess its planned slice size separately rather than using the per-100g figure alone.
-
Replenishing hot pizza without a display plan
A hot buffet needs space and equipment for cooked batches. Food Standards Agency and GOV.UK caterer guidance specifies hot holding at 63°C or above, or display for up to two hours on one occasion if hot holding is not possible.
Plan cooking batches and record when food goes on display so staff can follow the applicable handling guidance.

Frequently asked questions
Should I choose the pizza with the lowest kcal per 100g?
Use cooked kcal per 100g for a like-for-like comparison, but also check the portion you will serve. ASDA Groceries lists Dr. Oetker Ristorante Vegan Margherita Pomodori at 221 kcal per 100g and 377 kcal per half pizza; Tesco Groceries lists Goodfella's Gluten Free Margherita at 227 kcal per 100g and 376 kcal per half. NHS Better Health notes that labelled portions may differ from your own.
Does vegan or gluten-free pizza suit every guest?
No dietary label establishes suitability for every allergy. ASDA Groceries lists wheat and a possible milk presence for the vegan Dr. Oetker pizza, while Tesco Groceries gives a wheat-trace warning for Goodfella's Gluten Free Margherita. Check the delivered packs and keep each variant identifiable.
How should a caterer handle hot pizza on a buffet?
Food Standards Agency and GOV.UK caterer guidance says to hold hot food at 63°C or above. If hot holding is not possible, it permits display for up to two hours on one occasion; follow the guidance’s handling directions afterwards. Cook each pizza according to its pack and plan manageable replenishment batches.
Must a wedding food business provide allergen information?
For food businesses in England, Northern Ireland and Wales, Food Standards Agency and GOV.UK allergen guidance dated 17 July 2026 says operators must provide allergen information for prepacked and non-prepacked food, including telling customers when listed allergens are ingredients. A wedding caterer operating in those jurisdictions should keep accurate information for every pizza served. This does not establish the separate position in Scotland.
How can I plan buffet slices using the nutrition label?
Decide the number and size of slices you intend to offer, then compare that plan with the label’s stated serving. NHS Better Health notes that the manufacturer’s portion may differ from yours, so a half-pizza calorie figure should not automatically be treated as the figure for one buffet slice.
