Ingredients Method

Ingredients

  

• 2 pounds lean ground beef (90% lean or higher)
• 1 large yellow onion, diced
• 1 red bell pepper, diced
• 1 green bell pepper, diced
• 4 cloves garlic, minced
• 2 tablespoons chili powder
• 2 teaspoons ground cumin
• 1 teaspoon smoked paprika
• 1 teaspoon dried oregano
• 1/2 teaspoon crushed red pepper flakes (optional, for heat)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 (28-ounce) can crushed tomatoes
• 1 (15-ounce) can tomato sauce
• 1 cup low-sodium beef broth
• 1 (15-ounce) can black beans, drained and rinsed
• 1 (15-ounce) can kidney beans, drained and rinsed
• 1 tablespoon tomato paste
• 1 teaspoon cocoa powder (optional, for depth)
• 1 teaspoon apple cider vinegar or lime juice (to finish)
• Olive oil or avocado oil for sautéing
• Optional toppings: shredded cheddar, Greek yogurt, sliced jalapeños, chopped cilantro, diced red onion, lime wedges

Method

 

1. Warm a large skillet over medium-high heat and add a drizzle of oil. Add the ground beef and break it up with a spoon. Cook until browned and most of the moisture cooks off, about 6–8 minutes. Drain excess fat if needed.
2. Stir in the diced onion and bell peppers. Cook 3–4 minutes until slightly softened. Add the garlic and cook 30 seconds, just until fragrant.
3. Sprinkle in chili powder, cumin, smoked paprika, oregano, crushed red pepper flakes (if using), salt, and black pepper. Stir 1 minute to toast the spices.
4. Transfer the beef mixture to the slow cooker. Add crushed tomatoes, tomato sauce, beef broth, black beans, kidney beans, and tomato paste. Stir to combine.
5. Set the slow cooker: Cook on Low for 6–8 hours or on High for 3–4 hours. The longer time on Low yields deeper flavor and a thicker texture.
6. About 30 minutes before serving, stir in cocoa powder if using. Taste and adjust salt and spices. If you want a bit more brightness, stir in apple cider vinegar or a squeeze of lime.
7. Serve hot with your favorite toppings. For extra protein, top with a dollop of plain Greek yogurt and a sprinkle of shredded cheddar.

Health Benefits

• High-quality protein: Lean beef provides complete protein for muscle repair and satiety. Beans add plant-based protein for a balanced profile.
• Fiber-rich: Black beans and kidney beans bring fiber that supports digestion, helps regulate blood sugar, and keeps you full longer.
• Nutrient-dense ingredients: Tomatoes, peppers, and spices offer antioxidants like lycopene and capsaicin, plus vitamins A and C.
• Lower added sugar and fat: Using lean beef and minimal added sweeteners keeps calories in check without sacrificing flavor.
• Customizable sodium: Choosing low-sodium broth and rinsing canned beans helps manage salt levels.

Common Mistakes to Avoid

• Skipping the browning step: Browning the beef builds flavor and improves texture. Don’t add raw beef straight to the slow cooker.
• Not draining excess fat: Too much grease can make the chili oily.

  Drain if your beef releases a lot of fat.

• Overcrowding with liquid: Slow cookers trap moisture. Start with the listed broth, then add more later only if needed.
• Under-seasoning: Taste near the end and adjust salt, acid, and spice. A splash of vinegar or lime can wake up the flavors.
• Adding dairy too early: If using cheese or yogurt, add at serving time.

  Dairy in the slow cooker can separate.

Variations You Can Try

• Extra-lean and extra-protein: Swap 1/2 pound of beef for 1/2 pound of lean ground turkey, or stir in 1 cup of cooked quinoa during the last hour.
• No beans (Keto-friendly): Skip the beans and add diced zucchini, mushrooms, and extra bell peppers. Reduce the broth slightly.
• Spicy smoky: Add 1–2 chopped chipotle peppers in adobo and an extra teaspoon of smoked paprika.
• Veggie boost: Stir in a handful of spinach or chopped kale in the last 15 minutes until wilted.
• Thicker Texas-style: Use only crushed tomatoes, skip tomato sauce, and simmer uncovered on High for the final 20–30 minutes.
• Beans your way: Swap in pinto or cannellini beans, or use all kidney beans if that’s your favorite.
• Make it dairy-free: Use dairy-free toppings like avocado slices and cilantro. The chili itself is naturally dairy-free.

FAQ

Can I make this chili on the stovetop instead?

Yes.

Brown the beef and veggies in a large pot, add the remaining ingredients, bring to a simmer, then cook on low for 60–75 minutes, stirring occasionally. Keep the lid slightly ajar to thicken.

How can I make it less spicy?

Skip the crushed red pepper flakes and choose mild chili powder. If it still feels too warm, stir in a spoonful of Greek yogurt or a touch of honey to balance the heat.

Can I use ground turkey or chicken?

Absolutely.

Use the same amount (2 pounds) of lean ground turkey or chicken. Add 1 tablespoon of olive oil when browning to prevent sticking and consider boosting spices slightly for fuller flavor.

What if my chili is too thick?

Stir in a little beef broth or water—start with 1/4 cup and add more as needed. Warm through and taste to adjust seasoning afterward.

What if my chili is too thin?

Uncover the slow cooker and cook on High for 20–30 minutes to reduce.

You can also stir in 1–2 tablespoons of tomato paste or a small handful of finely crushed tortilla chips to thicken.

How do I add more protein without changing the flavor?

Top with Greek yogurt and shredded cheese, or stir in a scoop of unflavored collagen peptides near the end—they dissolve easily and don’t affect taste.

Is this recipe gluten-free?

Yes, as written it should be gluten-free. Just confirm your broth, spices, and toppings are certified gluten-free to avoid cross-contamination.

This slow cooker high protein beef chili is hearty, simple, and full of bold, cozy flavors. It fits into busy schedules, feeds a crowd, and makes leftovers you’ll actually look forward to.
