Add the diced onion to the skillet and sauté for another 4-5 minutes until softened. Stir in the minced garlic and cook for an additional 30 seconds, until fragrant.
3. Season the Meat
Sprinkle in the cumin, chili powder, garlic powder, oregano, salt, and black pepper. Stir well to coat the meat in the seasonings, cooking for another minute to enhance the flavors.
4. Transfer to the Slow Cooker
Carefully transfer the beef mixture into a 6-quart slow cooker.
5. Add the Remaining Ingredients
Pour in the black beans, kidney beans, diced tomatoes (with juice), diced tomatoes with green chiles (with juice), and tomato sauce. Stir everything together until well combined.
6. Slow Cook to Perfection
- On Low: Cook for 6-8 hours for the best flavor development.
- On High: Cook for 3-4 hours if you’re short on time.
7. Final Adjustments and Serving
Once the chili is done, taste and adjust seasoning if necessary. Serve warm with your favorite toppings.
Pro Tips & Variations
- Spicier Chili: Add ½ teaspoon of cayenne pepper or an extra can of diced green chiles.

- Vegetarian Option: Replace ground beef with lentils or plant-based crumbles.

How to Serve Classic Slow Cooker Chili
A bowl of slow cooker chili is a meal on its own, but the right toppings and side dishes can elevate the experience. Chili is highly customizable, allowing you to adjust the texture, spice level, and richness with various add-ons.
Best Toppings for Chili
- Shredded Cheese: Cheddar, Monterey Jack, or Pepper Jack melt beautifully into the hot chili.
- Sour Cream: Adds a cool, creamy contrast to the heat.
- Green Onions: Provide a fresh, mild onion flavor.
- Avocado Slices: Creamy and rich, balancing the spices.
- Tortilla Chips: Great for scooping up chili or adding a crunchy texture.
- Jalapeños: Fresh or pickled slices for extra heat.
- Cilantro: A bright, fresh herb that enhances the flavor.
- Crushed Crackers or Cornbread Crumbles: Soak up the chili and add texture.
Each topping offers a different flavor element, allowing you to personalize your bowl to your liking.

Common Mistakes & How to Avoid Them
Even though slow cooker chili is easy to prepare, a few common mistakes can affect the final result. Here’s how to avoid them for a perfectly balanced and flavorful chili.
1. Skipping the Browning Step
Browning the ground beef before adding it to the slow cooker enhances its flavor and texture. Without this step, the chili may taste bland, and the meat may have a boiled texture.
Solution: Always brown the meat in a skillet before transferring it to the slow cooker.
2. Overcooking on High Heat
While it’s tempting to speed up the cooking process, chili develops the best flavors when cooked low and slow. Cooking on high heat for too long can make the meat tough and reduce the depth of flavor.
Solution: If time allows, cook on low for at least 6 hours for the best results.
3. Adding Beans Too Early
Beans can become overly soft and mushy if they cook for too long in the slow cooker.
Solution: If using canned beans, add them during the last hour of cooking.
4. Not Tasting and Adjusting Seasoning
Chili flavors can develop differently depending on the ingredients and cooking time. If you don’t taste and adjust the seasoning before serving, it may end up too bland or too salty.
Solution: Before serving, taste the chili and adjust salt, spice, or acidity as needed. Adding a small amount of sugar or a splash of lime juice can help balance the flavors.
5. Making Chili Too Watery
If the chili is too thin, it won’t have the thick, hearty consistency that makes it satisfying.
Solution: Let the chili simmer uncovered for the last 30 minutes or stir in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons water).
Perfect Side Dishes for Chili
Pairing chili with the right side dish enhances the meal. Here are eight great options:
1. Classic Cornbread
Cornbread is a traditional chili pairing. Its slightly sweet flavor balances the spice of the chili, and its crumbly texture soaks up the sauce. Serve warm with butter for the best experience.
2. Garlic Bread
A slice of garlic bread adds a crispy, buttery element that complements the richness of the chili. The strong garlic flavor also enhances the seasoning in the dish.
3. Baked Potatoes
A baked potato topped with chili turns into a hearty meal. The soft, fluffy interior of the potato absorbs the flavors of the chili, creating a satisfying combination.
4. Rice
White or brown rice makes a great base for chili, stretching the meal further and providing a neutral, slightly chewy texture that complements the bold flavors of the dish.
5. Grilled Cheese Sandwich
A classic grilled cheese pairs well with chili, offering a rich, cheesy contrast to the spice and tomato-based sauce.
6. Tortilla Chips & Guacamole
For a Tex-Mex twist, serve chili with tortilla chips and guacamole. The creamy avocado balances the spice, while the crunchy chips add texture.
7. Coleslaw
A light and tangy coleslaw provides a refreshing contrast to the heavy, rich chili. The crisp texture and acidity cleanse the palate between bites.
8. Roasted Vegetables
Oven-roasted vegetables like bell peppers, zucchini, and carrots add a healthy, slightly sweet contrast to the chili’s savory depth.
Each of these sides complements the chili in different ways, from adding crunch to balancing heat with sweetness. Whether you prefer a classic pairing like cornbread or a lighter option like coleslaw, the right side dish can turn this meal into a complete feast.

Expert Tips for the Best Slow Cooker Chili
A few simple tricks can take this chili from good to great. Here are some expert tips to enhance the flavor, texture, and overall quality of your slow cooker chili.
1. Add a Splash of Beer or Coffee for Depth
Dark beer or brewed coffee enhances the chili’s depth of flavor, adding a slightly smoky, bitter note that balances the acidity of the tomatoes. Add about half a cup along with the other liquids.
2. Use Fire-Roasted Tomatoes for Extra Smokiness
Fire-roasted canned tomatoes provide a subtle smoky flavor that adds complexity to the chili. If available, swap regular diced tomatoes for fire-roasted ones.
3. Simmer Uncovered at the End for a Thicker Texture
If the chili is too thin after slow cooking, remove the lid and let it simmer uncovered for the last 30 minutes to help it thicken naturally.
4. Let the Chili Rest Before Serving
Allowing chili to sit for 15-20 minutes after cooking helps the flavors meld further, creating a more balanced dish.
5. Customize the Spice Level
For more heat, add cayenne pepper, diced jalapeños, or an extra can of diced green chilies. For a milder version, reduce the chili powder and skip the spicy additions.
Storage & Reheating Instructions
How to Store Leftovers
Slow cooker chili stores well, making it perfect for meal prep.
- In the Refrigerator: Allow the chili to cool completely before transferring it to an airtight container. Store in the fridge for up to 4 days.
- In the Freezer: Portion the chili into freezer-safe containers or resealable bags, leaving some space for expansion. Store for up to 3 months.
Best Ways to Reheat Chili
- On the Stovetop: Reheat over medium heat, stirring occasionally, until warmed through. Add a splash of water or broth if it thickens too much.
- In the Microwave: Heat in 30-second intervals, stirring in between, until hot.
- From Frozen: Thaw in the refrigerator overnight before reheating. For a quicker option, place the frozen chili in a pot over low heat, stirring occasionally.
