Ingredients for Chili Recipe for 100 Servings

Feeding 100 means bold flavors in bulk. These ingredients scale perfectly for a crowd-pleasing chili.

The ground beef is the foundation—80/20 lean-to-fat ratio keeps it juicy through long cooking. Costco or Sam’s Club are ideal for bulk purchases of both meat and canned goods. Beans should be drained and rinsed to avoid excess sodium (canned is fine for this scale). For tomatoes, San Marzano canned tomatoes offer superior quality if you’re serving discerning palates. Always taste and adjust the salt at the end—it concentrates as the chili reduces.

Need to stretch further? Add more beans or swap half the beef for ground turkey. No chili powder? Blend equal parts cumin, paprika, and cayenne for a DIY version. Fresh jalapeños can replace some bell peppers for heat. For a vegetarian version, substitute lentils or textured vegetable protein for the beef. The spices can be adjusted to taste—start with less and add more as it cooks.

This chili actually improves overnight. Store in the fridge for up to 4 days or freeze for 3 months. For serving, keep it warm in a slow cooker or chafing dish—it holds well for 4-6 hours. Portion into smaller containers for easier reheating.

Step-by-Step Instructions for Chili

This professional method ensures consistent, flavorful results for large-scale batches every time.

Step 1: Brown the Ground Beef Thoroughly

In a large commercial stockpot, cook the 25 lb ground beef over medium-high heat in batches to avoid overcrowding. Break it apart with a sturdy wooden spoon as it cooks, ensuring it browns evenly rather than steams.

You’ll know it’s ready when the meat is no longer pink and has developed a deep, rich color. This process should take 15-20 minutes per batch. Drain excess fat between batches, leaving just enough to coat the bottom—about ¼ cup—for the next step.

Step 2: Build the Flavor Foundation

Add the 10 whole yellow onions (finely diced) to the pot with the browned beef. Cook for 8-10 minutes until they soften and become translucent. Then stir in the 50 cloves garlic cloves (minced) and 15 whole green bell peppers (diced into ½-inch pieces).

Cook this mixture for another 5-7 minutes until the peppers begin to soften. This step develops the aromatic base that gives chili its depth. Watch for the onions to turn a light golden color—this visual cue indicates they’ve caramelized slightly, enhancing sweetness.

Step 3: Incorporate Spices and Tomatoes

Stir in the 1 cup chili powder, 0.5 cup ground cumin, 0.5 cup smoked paprika, 0.5 cup dried oregano, 0.75 cup salt, and 0.5 cup black pepper. Toast the spices for 2 minutes to bloom their flavors—this step is critical for maximum aroma.

Add the 4 cans tomato paste and cook for another 3-4 minutes, stirring constantly to prevent burning. The mixture should darken slightly and become fragrant. Then pour in the 8 cans diced tomatoes (with juices) and 8 cups beef stock, stirring to combine everything thoroughly.

Step 4: Simmer and Add Beans

Bring the mixture to a boil, then reduce heat to low and let it simmer uncovered for 1 hour. This allows the flavors to meld and the liquid to reduce slightly. Stir occasionally to prevent sticking, especially at the bottom of the pot.

After the initial simmer, add the 10 lb kidney beans, 10 lb black beans, and 10 lb pinto beans (all drained and rinsed). Simmer for another 30-45 minutes until the chili thickens to your desired consistency. The beans should be tender but still hold their shape.

Taste and adjust seasoning if needed, though the initial measurements should provide a well-balanced flavor profile for this large batch.
