DIY Pizza Night With a Backyard Wood-Fired Oven

For a make-your-own pizza night, plan on one 12-inch pizza for every two adults and make one dough ball of about 280 grams for each pizza. A 12-inch pizza cut into 6 slices gives two adults 3 slices each, and 3 slices is the average adult appetite the rest of this site uses.

The math works the same way as ordering from a pizzeria. The big differences are timing and setup. A wood-fired oven needs days of curing before the first party and a slow, steady fire before each bake, and guests will build their own pizzas at a topping bar while you run the oven.

This guide uses the Chicago Brick Oven CBO-500 DIY Kit as the example oven, and the manual for that oven is the source for the oven steps. The numbers on this page do not depend on which oven you own.

How many pizzas to make

Wood-fired pizzas are small by delivery standards, and the Associazione Verace Pizza Napoletana (AVPN), which sets the standard for Neapolitan pizza, caps a Neapolitan pizza at 35 centimeters, or about 14 inches. We count each one as a 12-inch pizza cut into 6 slices, the same as a medium in the calculator. Pick the appetite level that fits your crowd and read across.

Guests	Young kids (2 slices)	Light eaters (2.5 slices)	Average adults (3 slices)	Hungry crowd (4 slices)
4	2	2	2	3
6	2	3	3	4
8	3	4	4	6
10	4	5	5	7
12	4	5	6	8
16	6	7	8	11
20	7	9	10	14

These counts round up to whole pizzas, just like a delivery order. Our guide to how much pizza per person explains when to move a crowd up or down a row.

A make-your-own night often lands on the hungry side of the table. Guests build a pizza, watch it bake, and then want to try a second combination. If pizza is the only food, use the 4-slice column. If you are also serving a big salad, grilled vegetables, or dessert, the 3-slice column is enough.

How much dough to make

The AVPN also ties dough weight to pizza size. Its regulations call for a 200 gram dough ball for a pizza of 22 to 24 centimeters and a 280 gram ball for a pizza of 28 to 35 centimeters. A 12-inch pizza is about 30 centimeters across, so 280 grams per pizza is a good planning number.

Multiply your pizza count by 280 grams, then add one spare ball. A digital kitchen scale makes it easy to portion the balls evenly. First-time stretchers often tear dough, and a pizza sometimes sticks to the peel on the way in. The spare ball keeps a torn pizza from leaving someone without dinner.

For toppings, the AVPN recipe for a Margherita uses 80 to 100 grams of mozzarella per pizza. Use 100 grams per pizza as your cheese budget. Guests at a topping bar tend to pile on more than a pizzaiolo would, and an overloaded pizza can bake unevenly with the cheese still cold in the center. A small serving spoon in each topping bowl keeps portions reasonable without anyone having to police them.

A worked example

Say 8 adults and 4 young kids are coming, and pizza is the main dish.

1. Adults: 8 × 3 slices = 24 slices.
2. Kids: 4 × 2 slices = 8 slices.
3. Total: 24 + 8 = 32 slices.
4. Pizzas: 32 ÷ 6 = 5.33, so you round up to 6 twelve-inch pizzas. That gives you 36 slices.
5. Dough: 6 pizzas × 280 grams = 1,680 grams, plus one spare ball for 1,960 grams total.
6. Cheese: 6 pizzas × 100 grams = 600 grams of mozzarella.

If this group is hungry teenagers after a game instead of young kids, count them at 4 slices each. The total becomes 40 slices, which rounds up to 7 pizzas.

Set up a topping bar

Guests building their own pizzas is the whole point of the night, so give the topping bar room. A folding table near the oven, but outside its clearance area, works well. Set it up in the order people will use it:

1. Put the dough balls first, each on a floured tray or in its own container.
2. Set a bowl of flour or semolina next to them for stretching.
3. Add the sauce with a ladle.
4. Put the cheese after the sauce.
5. Line up the toppings, with the most popular ones last so the line keeps moving.
6. End at the peel, where an adult takes over.

The kit comes with one peel. A second pizza peel lets the next guest build a pizza while the first one bakes.

Keep wet toppings in check. Fresh tomatoes, raw mushrooms, and pineapple release water as they bake, and that water pools in the center of the pizza. Pat wet toppings dry and use a thin layer of sauce.

The Chicago Brick Oven manual says never to allow anyone under 18 to operate the oven. Kids can stretch dough and add toppings, but an adult should launch, turn, and pull every pizza.

Plan the oven days ahead

A new wood-fired oven is not ready for a party the day it is assembled. The Chicago Brick Oven manual lists several steps that have to happen before you cook for guests.

Build a proper base

The CBO-500 DIY Kit includes the oven pieces, an install kit, and a peel, brush, and infrared thermometer. It does not include the supporting structure or the enclosure. The manual gives the raw weight of the CBO-500 oven as 350 pounds and says every CBO oven requires a properly poured foundation. The kit has a 27 by 22 inch cooking surface.

Cure it slowly

The manual has you keep the first fires small and hold the oven as close to 212°F as possible, without going over, for 2 to 3 days. The low heat drives out moisture trapped in the oven and the masonry around it. According to the manual, a large fire at the start can permanently damage the oven and may void the warranty. The manual also says to re-cure the oven if it has sat unused for a long time or gotten wet.

Do two practice bakes

The manual says to cook something simple, such as a plain pizza shell, the first two times you use the oven, and to throw that food away without eating it. You can start eating from the oven on the third bake. Do those practice bakes before the party so your guests get the third one.

Leave room around it

Check the clearance rules before you pick a spot. For the CBO-500 and CBO-750, the manual requires at least 10 inches between the sides and back of the oven and anything combustible. It requires 30 inches on each side of the door opening and 36 inches in front of it. That front clearance is where people will stand, so keep the topping table and chairs outside it. Check local rules on wood-burning equipment as well.

Fire the oven on party day

Start the fire well before guests arrive. The manual describes the process this way:

• Start with dry kindling about 10 inches inside the front of the oven. Never use lighter fluid or other starter liquids.
• Add small pieces of wood and let the temperature rise slowly.
• About 20 minutes after the fire is going, add larger chunks and start moving the fire toward the back.
• The dome turns black from smoke first. The oven reaches about 700°F when the inner walls turn from black to a whitish gray, and you want the whole dome to reach that color.

Use dry hardwood only. The manual recommends oak, ash, beech, and maple, and it says resinous, treated, or scrap wood should not go in a cooking oven. Wet wood produces heavy smoke, and your guests will be standing downwind of it.

For pizza, push the fire to the back and keep a small ember bed there, which the manual suggests should be about 4 by 8 inches. Brush the front of the hearth clean and bake with the door open. The AVPN standard for Neapolitan pizza is a bake of 60 to 90 seconds, with the floor at about 380 to 430°C (roughly 716 to 806°F) and the dome at about 485°C (roughly 905°F). Expect your first pizzas at home to take longer while you learn to turn them.

Because the bake is so short, the topping bar usually sets the pace. Two or three guests building pizzas at once will keep one person at the oven busy.

Food safety and cleanup

Pizza straight from a wood-fired oven gets eaten fast, but toppings and leftovers still follow the usual rules. USDA guidance says perishable food should not sit at room temperature for more than two hours, or more than one hour when the air is above 90°F. The two-hour limit applies to the cheese, meats, and cut vegetables on the topping bar as well as to finished pizza. Put out small bowls and refill them from the refrigerator instead of setting everything out at once.

Refrigerate leftover pizza within two hours. USDA guidance says most cooked leftovers keep for 3 to 4 days in the refrigerator.

The oven stays hot for hours after the last pizza comes out. The manual says to let the flames burn down and wait until the oven is below 200°F before closing the decorative door. Brush the ashes out after each use into a metal container with a tight-fitting lid, and set that container on the ground or a noncombustible surface away from anything that can burn. Keep the ashes in the closed container until every cinder has cooled.

When to order instead

A backyard oven is a project, and some nights the weather or the guest list makes it the wrong choice. If rain moves the party indoors or the headcount doubles, the calculator will turn the same guest list into a delivery order in a few seconds. Our party pizza guide covers toppings and serving for a delivered order.
