Classic Seven-Layer Dip for 24
These are estimates. They come from rules of thumb, not a recipe we tested at this size. Go by the recipe's own doneness cues and a thermometer, and taste as you go.
The plan
Make it 2 times over: about 24 servings.
The recipe serves 12. How it cooks: no cooking.
Pans, pots and the oven
- About 3 ½ quarts: your biggest mixing bowl.
Timing
- Prep: about 35 minutes of hands-on work (the recipe's 20 minutes, times 2, a little faster once you're set up).
Good to know
- Keep it cold until serving (40°F or colder), and set out a smaller bowl at a time, or set the bowl over ice.
Ingredients for about 24
Every amount × 2, except the marked ones: those don't grow in a straight line.
- Bean layer
- 2 cans refried beans, 16 oz
- 2 tsp chili powder
- 1 tsp ground cumin
- ½ tsp garlic powder
- Sour cream layer
- 2 cups sour cream
- 2 tbsp lime juice
- Guacamole layer
- 4 large avocados, ripe
- 2 tbsp lime juice
- ½ tsp kosher salt Start with ⅜ tsp. Add 3/4 of it, then taste near the end and add the rest only if it needs it. In a big batch salt adds up fast, and broth, cans and cheese bring their own.
- Top layers
- 2 cups salsa, drained of extra liquid
- 3 cups cheddar cheese, or a Mexican blend, shredded
- 2 cups cherry tomatoes, quartered
- 6 green onions, sliced
- ½ cup sliced black olives, drained (optional)
- tortilla chips, to serve
Rounded to kitchen measures. Eggs are rounded up to whole eggs.
Keeping a big batch safe
- Keep hot food at 140°F or hotter and cold food at 40°F or colder; nothing sits out more than 2 hours (1 hour above 90°F). (USDA FSIS: "Danger Zone" (40°F to 140°F))
- Split big batches into shallow containers so they cool quickly. Hot food can go straight into the fridge. (USDA FSIS: Leftovers and Food Safety)

How we work it out
- How it cooks decides how it grows. Baked dishes and casseroles are made as separate batches of the recipe as written, one pan's worth at a time. Soups, stews and chili go in one bigger pot, or several. Slow cooker and pressure cooker recipes get one batch per cooker or per round. Roasts become more roasts, not a bigger one. Skillet, griddle, grill and fried recipes cook in rounds.
- Pans and the oven. We assume a home oven with two racks, two baking dishes or cake pans per rack, or one sheet pan per rack. More pans than that means another round in the oven.
- Pots. The volume comes from the weight of the ingredients (about a liter for each kilogram; dry pasta, rice and grains count 2½ times, since they soak up water), in a pot no more than 3/4 full.
- What we don't simply multiply. Salt: add 3/4, taste, then the rest. Cayenne, chiles and hot sauce: start with 2/3. Ground spices and dried herbs: start with 3/4 once it's 3 batches or more. Bay leaves and other whole spices: about half the extra. Baking soda, baking powder and yeast: batch by batch. Frying oil and the water for boiling: by the pot, not the recipe. A big pot of soup or stew: hold back a tenth of the liquid.
- Timing. Each extra batch adds about 3/4 of the recipe's prep time. A big pot takes about 3 more minutes per extra quart to come to a simmer on one burner. Meat browns in batches no bigger than the recipe's. A full oven bakes a little slower: swap and turn the pans halfway, and allow 5 to 10 minutes more.
These are our rules of thumb, not tests of each recipe at each size. The recipe's own doneness cues and a thermometer come first.
