How To Make Crock Pot Cheddar Chili Mac
- Brown the beef:
- Start by browning ground beef in a skillet over medium heat for about 5 minutes until no pink remains. Break the meat into small crumbles as it cooks for even texture throughout the dish. Drain thoroughly to prevent excess grease in your final dish.
- Prepare pasta:
- Cook macaroni in boiling salted water for about 2 minutes less than package directions indicate. This undercooking prevents the pasta from becoming mushy during the slow cooking process. Rinse briefly with cold water to halt cooking.
- Combine ingredients:
- Add browned beef, cooked macaroni, undrained chili beans, drained tomatoes with green chiles, chili powder, and garlic salt to your slow cooker. Stir thoroughly until all ingredients are evenly distributed. Make sure to scrape the bottom and sides to incorporate everything.
- Add cheese topping:
- Sprinkle the shredded cheddar cheese evenly across the top of the mixture creating a blanket of cheese that will melt beautifully during cooking. Avoid stirring after this step to maintain that perfect cheesy top layer.
- Slow cook to perfection:
- Cover and cook on low for 2 hours or high for 1 to 1.5 hours. If your slow cooker has hot spots, rotate the insert halfway through cooking time. The dish is ready when the cheese is completely melted and the edges are slightly bubbling.

The mild chili beans are truly the secret ingredient in this recipe. My grandmother always said good chili was about finding the right beans, and after testing countless varieties, these mild chili beans provide that perfect balance of flavor without requiring additional seasoning work. Every time I open a can, I think of her kitchen and how she'd approve of this modern twist on comfort food.
Serving Suggestions
This Crock Pot Cheddar Chili Mac is a meal in itself, but adding a few simple sides can elevate the dining experience. A crisp green salad with a light vinaigrette provides refreshing contrast to the hearty main dish. Cornbread makes an excellent accompaniment soaking up the savory sauce beautifully. For a complete comfort food experience, serve with garlic bread for scooping up every last bite.
Make It Your Own
The beauty of this recipe lies in its adaptability. Swap ground turkey or chicken for a lighter version with minimal flavor difference. Vegetarians can substitute a plant based crumble or an extra can of beans for the meat. Spice lovers can increase the heat by adding diced jalapeños or a dash of hot sauce. For extra vegetables, mix in diced bell peppers, corn, or zucchini. The recipe maintains its integrity while accommodating dietary preferences or whatever ingredients you have on hand.
Storage and Reheating
Store leftovers in airtight containers in the refrigerator for up to 4 days. The flavors actually develop and improve overnight, making this an excellent make ahead option. To reheat, microwave individual portions covered with a damp paper towel to prevent drying out. For family servings, reheat in a covered casserole dish in a 350°F oven until warmed through. Add a sprinkle of fresh cheese before reheating for that freshly made experience.

Kid Friendly Variations
This dish naturally appeals to children with its familiar pasta and cheese combination. For extremely picky eaters, consider using regular diced tomatoes instead of those with green chiles. Let kids customize their own bowls with toppings like extra cheese, sour cream, or even crushed tortilla chips for added texture. Creating a toppings bar allows everyone to personalize their serving while still enjoying the same base meal perfect for families with varying preferences.
