Dice the yellow onion into 1/2-inch pieces, chop the celery ribs into 1/4-inch pieces, dice the green bell pepper into 1/2-inch pieces, and mince the garlic cloves. In a small bowl, combine the salt, garlic powder, onion powder, sugar, chili powder, and ground cumin—this spice blend will distribute evenly throughout the chili and ensure consistent flavor. Having everything prepped and measured before you start cooking makes the assembly into the crockpot seamless and prevents any ingredients from being forgotten.

Heat a large skillet over medium-high heat and add the ground beef. Break it apart with a spoon as it cooks, stirring occasionally, until no pink remains and the beef is lightly browned (about 8-10 minutes). This browning step develops deeper flavor through the Maillard reaction, which will make your finished chili taste richer. Drain the cooked beef in a colander to remove excess fat, then set aside.

Add the browned beef from Step 2 to your crockpot, then layer in the diced onion, celery, and green bell pepper. Pour in the tomato sauce, tomato paste, diced tomatoes and chilies, and beer. Add the minced garlic and the spice blend from Step 1, then stir everything together until well combined. The beer adds a subtle complexity and helps tenderize the meat during the long cooking process, so don't skip it even if you're not a beer drinker—it cooks off and just enhances the depth of flavor.

Cover the crockpot and cook on low for 8 hours (or on high for 4-6 hours if you're short on time). The long, gentle cooking allows the flavors to meld together and the vegetables to soften completely. About 30 minutes before you're ready to serve, stir in the drained kidney beans and let them heat through—adding them near the end prevents them from breaking down and turning to mush.

Uncover the crockpot and turn the heat to high for the final 30 minutes. This allows excess moisture to evaporate, thickening the chili to your desired consistency. Stir occasionally during this time to ensure even heat distribution. Taste and adjust seasonings as needed—chili often needs a bit more salt or a touch of sugar at the end to round out the flavors.
