Ingredients
- 1½ pounds ground beef (80/20 blend works best)
- 1 large yellow onion, diced (about 1 cup)
- 3 cloves garlic, minced
- 1 bell pepper, diced (red or green)
- 2 cups elbow macaroni, uncooked
- 1 can (15 oz) kidney beans, drained and rinsed
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (14.5 oz) diced tomatoes, undrained
- 1 can (8 oz) tomato sauce
- 2 cups beef broth
- 2 tablespoons chili powder
- 1 tablespoon cumin
- 1 teaspoon smoked paprika
- 1 teaspoon oregano
- ½ teaspoon garlic powder
- Salt and black pepper to taste
- 2 cups sharp cheddar cheese, shredded
- ½ cup sour cream
- 2 green onions, chopped (for garnish)
Step-by-Step Instructions
Step 1: Prepare the Base Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until browned and no longer pink, about 6-8 minutes. Drain excess fat, leaving about 1 tablespoon in the pan.
Step 2: Sauté Aromatics Add diced onion and bell pepper to the skillet with the beef. Cook for 3-4 minutes until vegetables begin to soften. Add minced garlic and cook for another 30 seconds until fragrant.
Step 3: Season the Mixture Sprinkle chili powder, cumin, smoked paprika, oregano, and garlic powder over the beef mixture. Stir well to coat everything evenly with spices. Cook for 1 minute to bloom the spices.
Step 4: Transfer to Crock Pot Transfer the seasoned beef mixture to your 6-quart slow cooker. Add uncooked elbow macaroni, kidney beans, black beans, diced tomatoes with their juice, tomato sauce, and beef broth. Stir everything together until well combined.
Step 5: Slow Cook Cover and cook on LOW for 4-5 hours or HIGH for 2-3 hours, until pasta is tender and flavors have melded together. Stir once halfway through cooking if possible.
Step 6: Add Cheese In the last 15 minutes of cooking, stir in the shredded cheddar cheese and sour cream. Cover and let the cheese melt completely, creating a creamy, rich sauce.
Step 7: Final Seasoning Taste and adjust seasoning with salt and pepper as needed. The dish should be well-seasoned but not overpowering.
Step 8: Serve Ladle into bowls and garnish with chopped green onions. Serve immediately while hot and creamy.
Things to Remember
Pasta Timing: Don’t add pasta too early or it will become mushy. The timing in this recipe ensures perfectly tender pasta that holds its shape.
Liquid Levels: The pasta will absorb liquid as it cooks, so don’t worry if the mixture seems soupy initially. It will thicken as it cooks.
Cheese Quality: Use freshly shredded cheese rather than pre-shredded for better melting and creamier texture. Pre-shredded cheese contains anti-caking agents that can affect texture.
Temperature Control: Avoid lifting the lid frequently as this releases heat and extends cooking time. Trust the process and let the slow cooker work.
Meat Selection: Ground beef with some fat content (80/20) provides better flavor than very lean ground beef, which can become dry.
What to Serve With Them
Crusty Bread: Warm cornbread or crusty sourdough bread is perfect for sopping up the flavorful sauce and adding textural contrast to the creamy dish.
Fresh Salad: A crisp green salad with simple vinaigrette helps balance the richness of the chili mac and adds fresh vegetables to the meal.
Avocado Slices: Creamy avocado provides a cooling contrast to the warm, spiced dish and adds healthy fats to round out the nutritional profile.
Pickled Jalapeños: For those who enjoy heat, pickled jalapeños add a bright, tangy kick that complements the rich, cheesy flavors perfectly.
Coleslaw: Cool, crunchy coleslaw provides a refreshing counterpoint to the warm, hearty chili mac and adds extra vegetables to the meal.
Mix It Up
Protein Variations: Substitute ground turkey, chicken, or even plant-based ground meat for different flavor profiles and dietary preferences.
Vegetable Additions: Stir in corn kernels, diced zucchini, or mushrooms during the last hour of cooking for extra nutrition and texture.
Spice Level: Add diced jalapeños, chipotle peppers in adobo, or cayenne pepper for more heat. Start small and build up to your preferred level.
Cheese Combinations: Try mixing cheddar with Monterey Jack, pepper jack, or even cream cheese for different flavor profiles and creaminess levels.
Bean Varieties: Experiment with pinto beans, navy beans, or cannellini beans instead of the kidney and black bean combination.

Keeping Them Fresh
Refrigeration: Store leftovers in the refrigerator for up to 4 days in airtight containers. The flavors actually improve after a day as they continue to meld together.
Freezing: This dish freezes well for up to 3 months. Portion into freezer-safe containers, leaving some room for expansion. Thaw overnight in the refrigerator before reheating.
Reheating: Add a splash of broth or water when reheating as the pasta may absorb liquid during storage. Heat gently to prevent the cheese from separating.
Make-Ahead Tips: You can brown the meat and prepare vegetables the night before, storing them covered in the refrigerator until ready to cook.
Kitchen Tips
Slow Cooker Size: A 6-quart slow cooker is ideal for this recipe. If using a smaller cooker, reduce ingredients proportionally to avoid overflow.
Browning Benefits: Don’t skip browning the meat – this step adds crucial flavor depth that can’t be achieved by simply adding raw meat to the slow cooker.
Stirring Strategy: Gentle stirring prevents pasta from sticking together, but avoid over-stirring which can break up the pasta and beans.
Texture Control: If you prefer a thicker consistency, remove the lid during the last 30 minutes of cooking to allow excess liquid to evaporate.
Frequently Asked Questions
→Can I use different pasta shapes?
Yes, but stick to sturdy shapes like penne, rotini, or shells that won’t break down during long cooking. Avoid delicate pasta like angel hair.
→ if I don’t have beef broth?
Chicken broth or vegetable broth work as substitutes. You can even use water with additional seasonings if needed.
→Can I make this dairy-free? Substitute the cheese with dairy-free alternatives and use coconut cream instead of sour cream. The texture will be slightly different but still delicious.
→How do I prevent the pasta from getting mushy?
Cook on LOW rather than HIGH, and don’t exceed the recommended cooking time. Adding pasta during the last 2 hours helps maintain better texture.
Yes, but you’ll need a large 8-quart slow cooker. Cooking times may need slight adjustment, so check for doneness earlier than indicated.
