I need a chili recipe for 20-25 people

I find that the pre-made kits cover about 4 servings... so get 7 of those, 14 pounds of meat, and however much tomato sauce it calls for, and go to town.

I use the Cook's Country version sans the beans since I don't do beans in chili. If you use the beans, 2 1/2 times the recipe will do fine or just triple it and freeze the rest. If you don't use the beans, I'd quadruple it at least. The recipe lists some accouterments, but I include cheeses, sour cream or Mexican sour cream, guac, and whatever else you like with chili.

Serves 8 to 10

Look for ancho chiles in the international aisle at the supermarket. Light-bodied American lagers, such as Budweiser, work best here. Serve chili with lime, sour cream, scallions, and cornbread.
Ingredients

2 ounces dried ancho chiles (4 to 6 chiles), stemmed, seeded, and flesh torn into 1-inch pieces
3 1/2 cups water
1 (28-ounce) can whole peeled tomatoes
3/4 cup crushed corn tortilla chips
1/4 cup canned chipotle chiles in adobo sauce plus 2 teaspoons adobe sauce
2 tablespoons vegetable oil
2 pounds 85 percent lean ground beef
Salt and pepper
2 pounds onions, chopped fine
2 jalapeño chiles, stemmed, seeds reserved, and minced
6 garlic cloves, minced
2 tablespoons ground cumin
2 tablespoons chili powder
1 tablespoon dried oregano
2 teaspoons ground coriander
2 teaspoons sugar
1 teaspoon cayenne pepper
1 1/2 cups beer
3 (15-ounce) cans pinto beans, rinsed

Instructions

1. Combine anchos and 1½ cups water in bowl and microwave until softened, about 3 minutes. Drain and discard liquid. Process anchos, tomatoes and their juice, remaining 2 cups water, tortilla chips, chipotle, and adobo sauce in blender until smooth, about 1 minute; set aside.

2. Heat 2 teaspoons oil in Dutch oven over medium-high heat until just smoking. Add beef, 1 teaspoon salt, and ½ teaspoon pepper and cook, breaking up pieces with spoon, until all liquid has evaporated and meat begins to sizzle, 10 to 15 minutes. Drain in colander; set aside.

3. Heat remaining 4 teaspoons oil in now-empty Dutch oven over medium-high heat until simmering. Add onions and jalapeños and seeds and cook until onions are lightly browned, about 5 minutes. Stir in garlic, cumin, chili powder, oregano, coriander, sugar, and cayenne and cook until fragrant, about 30 seconds. Pour in beer and bring to simmer. Stir in beans, reserved ancho-tomato mixture, and reserved cooked beef and bring to simmer. Cover, reduce heat to low, and cook, stirring occasionally, until thickened, 50 to 60 minutes. Season with salt to taste. Serve.

It's hard to go wrong with the 2 alarm chili kits. That's what I would do.

It's really just packets of premeasured seasoning that you add your own ground meat, rotel, tomato sauce, and whatever else it calls for. I like beans in mine, some don't. I've cooked the 2 alarm chili using deer for our office and shop a few times and had people tell me I should enter a chili cookoff. It's that good IMO and easy.
