This keto chili recipe is an absolute game-changer for anyone following a low-carb lifestyle! It’s hearty, deeply flavorful, and packed with protein while keeping carbs minimal. Unlike traditional chili loaded with beans and sugar, this version uses ground beef, rich spices, and plenty of vegetables to create that authentic chili experience you crave.
What makes this recipe so special is the combination of quality ingredients and proper layering of flavors. We’re talking about a slow-cooked masterpiece that tastes even better the next day. The beauty of keto chili is that it’s incredibly versatile—you can make it as spicy or mild as you like, add different types of meat, or customize the vegetables to your preference. It’s the kind of meal that works perfectly for meal prep, weekend gatherings, or those cozy nights when you want something warm and satisfying.
The secret to the best keto chili lies in taking time with your spices and letting them bloom in the fat from the meat. We’re building layers of flavor here—the smokiness from the chili powder, the depth from cumin, the complexity from tomato paste, and the richness from quality beef. You’ll also appreciate how this recipe is naturally keto-friendly without any weird substitutions or complicated steps. Just honest, delicious chili that happens to fit your macros.
I love serving this alongside homemade baking powder biscuits for those who aren’t strictly keto, or topped with sour cream, cheddar cheese, and jalapeños for everyone. You could even pair it with grilled eggplant for a unique side dish.

Ingredients
- 3 tablespoons olive oil or avocado oil
- 2 pounds ground beef (80/20 blend works best)
- 1 large yellow onion, diced
- 4 cloves garlic, minced
- 3 tablespoons tomato paste
- 2 tablespoons chili powder (adjust to taste)
- 1 tablespoon ground cumin
- 1 teaspoon smoked paprika
- 1 teaspoon oregano
- ½ teaspoon cayenne pepper (optional, for heat)
- ½ teaspoon black pepper
- 1 teaspoon sea salt (adjust to taste)
- 1 can (28 ounces) crushed tomatoes
- 1 can (14.5 ounces) diced tomatoes
- 2 cups beef broth or beef stock
- 2 large bell peppers (red or green), diced
- 8 ounces mushrooms, chopped (optional but recommended)
- 2 jalapeños, diced (optional)
- 1 tablespoon apple cider vinegar
- 1 teaspoon Worcestershire sauce
- Toppings: shredded cheddar cheese, sour cream, fresh cilantro, diced onion, jalapeño slices
Instructions
- Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Once shimmering, add the ground beef in batches, breaking it up as it cooks. Don’t crowd the pot—you want the meat to brown, not steam. This should take about 8-10 minutes total. Once all the beef is browned and any excess fat has been poured off (save about 2 tablespoons for flavor), remove the meat to a plate and set aside.
- In the same pot with the remaining fat, add the diced onion and cook for 4-5 minutes until it becomes translucent and slightly caramelized. Add the minced garlic and cook for another minute until fragrant, stirring constantly to prevent burning.
- Push the onion and garlic to the sides of the pot and add the tomato paste to the center. Let it sit for about 1-2 minutes, then stir it into the onions and garlic. This step blooms the tomato paste and intensifies its flavor—don’t skip it!
- Reduce heat to medium and add all your dried spices: chili powder, cumin, smoked paprika, oregano, cayenne pepper, black pepper, and sea salt. Stir constantly for about 2-3 minutes. This blooming process releases the essential oils from the spices and creates a rich, aromatic base for your chili.
- Return the browned ground beef to the pot and stir well to combine with the spice mixture. Cook for another 2 minutes, stirring occasionally.
- Add the crushed tomatoes, diced tomatoes (with their juices), and beef broth. Stir well to combine everything. Bring the mixture to a gentle simmer, scraping up any browned bits from the bottom of the pot (these add incredible flavor!).
- Once simmering, add the diced bell peppers, mushrooms (if using), and jalapeños (if using). Stir to combine. Reduce the heat to low and let the chili simmer uncovered for at least 2 hours, though 2.5 hours is ideal. The longer it simmers, the more the flavors will develop and meld together.
- Stir occasionally throughout the cooking time (about every 20-30 minutes) to prevent sticking and ensure even cooking. If the chili seems too thick, add more beef broth. If it seems too thin, let it simmer uncovered longer to reduce.
- In the final 10 minutes of cooking, taste the chili and adjust seasonings as needed. Add the apple cider vinegar and Worcestershire sauce, which add depth and a subtle tang that brings all the flavors together. Stir well.
- Remove from heat and let the chili rest for 5-10 minutes before serving. This allows the flavors to settle and makes serving easier.
- Ladle into bowls and top with your choice of toppings: shredded cheddar cheese, sour cream, fresh cilantro, diced onion, or jalapeño slices. Serve hot and enjoy!
Pro Tips
The choice of ground beef is important—go for 80/20 blend rather than extra-lean. The fat content is essential for flavor and helps you reach your fat macros on keto. You can also use ground chuck or a mix of beef and ground lamb for variation.
Tomato paste is keto-friendly in small quantities because we’re using just 3 tablespoons. The canned tomatoes do contain some carbs, but they’re minimal when divided among 8-10 servings. Choose no-sugar-added versions when possible.
Don’t rush the initial browning of the meat—this is where you develop fond (those browned bits) that add incredible depth to your finished chili. Proper browning creates complexity that you simply cannot achieve any other way.
The spice blend is completely customizable based on your preferences. If you like spicier chili, increase the chili powder, cayenne, or add fresh jalapeños. If you prefer milder, reduce these quantities. Always taste as you go.
This recipe freezes beautifully for up to 3 months. Make a double batch and freeze in portions for quick keto-friendly meals. Thaw in the refrigerator overnight and reheat on the stovetop or in the microwave.
Leftovers actually taste better than the first day because the flavors continue to develop. Store in an airtight container in the refrigerator for up to 5 days. You can use it as a base for keto nachos with pork rinds, stuff it into bell peppers, or serve over cauliflower rice for a different texture.
For meal prep, portion into containers and top with cheese and sour cream right before eating for the best texture. The chili will keep those toppings from getting soggy.
If you’re cooking for mixed dietary needs, serve the chili with optional toppings and let guests customize. Those not on keto can enjoy it with cornbread or regular biscuits.
The net carbs per serving are approximately 7-8 grams, depending on your specific vegetables and exact portion size, making this perfectly keto-compliant for most people following a 20-50g daily carb limit.
