• Swap beef broth for chicken broth if that is what you have on hand

Step by Step Instructions

Step 1: Brown the beef
In a skillet over medium-high heat, brown the ground beef with the diced onion and garlic until fully cooked. Drain excess fat. This step is optional but adds significant depth of flavor.

Step 2: Add everything to the crockpot
Transfer the browned beef to the slow cooker. Add the beans, tomatoes, tomato paste, beef broth, and all the spices. Stir to combine.

Step 3: Cook
Cover and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours.

Step 4: Adjust seasoning
Taste the chili and adjust salt, chili powder, or cumin as needed. If the chili is too thick, add a splash of broth. If too thin, cook uncovered on HIGH for 20 to 30 minutes.

Step 5: Serve
Ladle into bowls and top with your favorite garnishes.

Tips and Tricks

• Browning the beef before adding it to the crockpot is worth the extra 10 minutes it adds a savory depth that slow cooking alone cannot replicate
• A square of dark chocolate or a tablespoon of instant coffee stirred in adds a surprising richness to the base without being detectable
• For a smokier flavor, add one chipotle pepper in adobo sauce, finely minced
• Chili always tastes better the next day after the flavors have had time to fully develop
• Freeze individual portions in zip-lock bags laid flat for space-efficient freezer storage

Serving Suggestions

• Topped with shredded cheddar cheese, sour cream, and sliced green onions
• With warm cornbread on the side for the classic game day combination
• Over white rice for a protein-loaded rice bowl
• Loaded onto baked potatoes with all the toppings
• In a bowl topped with crushed tortilla chips for added texture

Mistakes to Avoid

• Skipping the browning step : while you can add raw ground beef to the crockpot, the flavor payoff from browning it first is significant.
• Not draining the beans : the liquid in canned beans is starchy and can make the chili gummy. Always drain and rinse before adding.
• Adding too much liquid : chili should be thick and hearty, not soupy. Start with less broth and add more if needed.
• Under-seasoning : chili needs bold seasoning. Taste and adjust throughout the cooking process.
• Opening the lid too frequently : every time you open the crockpot during cooking, you lose heat and extend the cooking time.

FAQ

Can I make this chili without browning the meat first?
Yes, you can add raw ground beef directly to the crockpot. Break it up well before cooking and stir it midway through. The flavor will be slightly less rich but the result is still a delicious chili.

How do I make this chili spicier?
Add one or two chipotle peppers in adobo sauce, increase the chili powder, or add a pinch of cayenne pepper. Taste and adjust gradually.

How long does this chili last in the fridge?
Up to 5 days in an airtight container. The flavor deepens significantly after the first day.

Can I freeze leftover chili?
Yes. Chili freezes exceptionally well for up to 3 months. Cool completely before freezing. Thaw overnight in the fridge and reheat on the stovetop.

Can I use ground turkey instead of beef?
Absolutely. Ground turkey (93/7 or leaner) makes an excellent high-protein, lower-fat alternative. Follow the same steps and cook times.
