Slow Cooker Chili Mac and Cheese with Ground Beef
This slow cooker chili mac and cheese brings together three comforting favorites—pasta, chili, and melted cheese—into one rich and satisfying meal. Tender spirali pasta cooks directly in a flavorful beef chili base, creating a hearty dish that’s packed with texture and bold flavor. It’s an easy, hands-off recipe that’s perfect for feeding a family.
The chili base features minced beef, kidney beans, chopped tomatoes, and warming spices like chili powder and cumin. Everything simmers slowly until rich and vibrant, before pasta is stirred in and cooked to your liking. Finished with generous handfuls of cheddar and mozzarella, the result is creamy, cheesy, and deeply comforting with just the right amount of heat.

kcalIngredients
1 onion, chopped
Peppers, chopped
Oil (for frying)
Tomato purée (tomato paste)
2 teaspoons crushed garlic
Chili powder (amount to taste)
1 teaspoon powdered cumin
1 pound minced (ground) beef
Salt, to taste
Kidney beans
1 can chopped tomatoes
Beef stock (1 stock pot or equivalent)
Spirali pasta (or other tube-shaped pasta such as macaroni, fusilli, or penne)
Cheddar cheese, a couple of handfuls
Mozzarella cheese, a couple of handfuls
Directions
- Soften the Vegetables
In a pan over medium heat, add a little oil and fry the chopped onion and peppers for a few minutes until slightly softened. You’re not looking to cook them completely—just take away the raw edge since they’ll continue cooking in the slow cooker. - Add Tomato Paste, Garlic, and Spices
Stir in the tomato purée (tomato paste), crushed garlic, chili powder, and powdered cumin. Mix well so the spices coat the vegetables evenly. Adjust the chili powder to your preferred level of heat. - Brown the Beef
Add the minced (ground) beef to the pan along with a pinch of salt. Cook until browned all over, breaking it up as it cooks. You don’t need to cook it through completely, but browning adds extra flavor. If your beef releases excess fat, drain it before transferring. - Transfer to the Slow Cooker
Spoon the beef and vegetable mixture into your slow cooker. - Add Beans, Tomatoes, and Stock
Add the kidney beans, chopped tomatoes, and beef stock. Stir everything together thoroughly to combine. - Slow Cook the Chili Base
Cover with the lid and cook on high for 4 hours. The mixture will become rich and deeply flavored. - Add the Pasta
After 4 hours, stir in the spirali pasta. Make sure the pasta is fully submerged in the liquid, as it will absorb moisture while cooking. If the mixture looks watery, don’t worry—the pasta will soak up much of the liquid. - Cook the Pasta
Replace the lid and cook for 15–20 minutes, or until the pasta is cooked to your liking. For a firmer texture, check at the 15-minute mark. - Stir in the Cheese
Just before serving, stir in a couple of handfuls of cheese. A combination of cheddar and mozzarella works especially well, giving both bold flavor and a gooey, stretchy texture. - Serve
Serve hot in bowls. This pairs beautifully with garlic dough balls or garlic bread on the side.

Notes
- If you prefer extra heat, use hot chili powder. For a milder version, stick with mild chili powder and adjust gradually to taste.
