This ultimate comfort food combines the best of both worlds — hearty beef chili meets creamy macaroni and cheese for a satisfying one-dish meal that's sure to please even the pickiest eaters. The combination creates a rich, flavorful dish that's perfect for weeknight dinners or casual gatherings.
I first started making this recipe when my kids were going through a picky eating phase. The familiar mac and cheese component got them to try the chili, and now they request this mashup weekly during the colder months.
Ingredients
- Lean ground beef: Provides the hearty base while still keeping the dish from becoming too greasy
- Bell peppers: Add a sweet crunch and vibrant color to balance the richness
- Kidney beans: Bring fiber and protein making this a complete meal
- Heavy cream: Creates that luxurious mac and cheese texture that makes this dish irresistible
- Mustard powder: Adds depth to the cheese sauce without overwhelming the flavor
- Hot sauce: Brings just enough heat to enhance the flavors without making it spicy
Step-by-Step Instructions
- Brown the Beef and Aromatics:
- Cook the ground beef in a large pot over medium-high heat until it begins to brown, then add onions and cook together until beef is fully browned and onions are soft and translucent. This foundation step builds flavor for the entire dish. Make sure to drain excess grease to prevent a greasy final product.
- Build the Chili Base:
- Add bell peppers and garlic, cooking until peppers soften. Then incorporate the chili seasoning and tomato paste, allowing them to toast slightly which activates their flavors and removes any raw taste. This quick cooking of the spices makes a noticeable difference in the final depth of flavor.
- Simmer the Chili:
- Pour in tomato sauce, diced tomatoes with their juice, and broth to create a rich, flavorful chili base. Let this mixture simmer partially covered, allowing it to reduce and concentrate in flavor. Add kidney beans toward the end of cooking to prevent them from becoming mushy. The longer this simmers, the more developed the flavors become.
- Create the Cheese Sauce:
- Make a roux by melting butter and whisking in flour until it bubbles but doesn't brown. Gradually add cream and milk in small portions, whisking constantly to prevent lumps. This slow addition is crucial for a smooth sauce. Once thickened, add seasonings and gradually incorporate cheese while keeping the heat low to prevent separation.
- Cook the Pasta:
- Boil the macaroni in well-salted water until just al dente. Undercook it slightly as it will continue to cook when baked. Drain thoroughly to prevent watery mac and cheese.
- Combine Components:
- Gently fold the mac and cheese with the chili, carefully combining for even distribution without breaking down the pasta. This step allows you to customize the ratio based on preference, using more chili for a heartier dish or more mac and cheese for a creamier result.
- Bake Until Bubbly:
- Top with additional cheese and bake just until melted and bubbly, creating that irresistible cheese pull when serving. Watch carefully to prevent browning or burning the cheese topping.

The chili seasoning is really the heart of this dish. While packet seasoning works perfectly, I often make my own blend with chili powder, cumin, oregano, and a pinch of cinnamon for depth. My grandmother taught me this trick, and it always reminds me of Sunday dinners at her house.
Make-Ahead Options
This dish is actually even better the next day after flavors have melded together overnight. You can prepare everything up to the baking stage, refrigerate, and then bake for about 20 minutes when ready to serve. Add the cheese topping just before baking for the best texture.
Customization Ideas
This recipe welcomes creative variations. Try using ground turkey instead of beef for a lighter option. Pepper jack cheese adds a nice kick, or mix in some smoked gouda for depth. For a spicier version, add diced jalapeños or a dash of cayenne to the chili. Vegetarians can substitute the beef with plant-based crumbles or extra beans and vegetables.
Serving Suggestions
Serve this hearty dish with a crisp green salad dressed with a vinaigrette to cut through the richness. A side of garlic bread is perfect for scooping up any extra sauce. Set out toppings like sour cream, sliced green onions, diced avocado, and extra hot sauce so everyone can customize their bowl.

Enjoy this ultimate comfort food that blends chili and mac and cheese into a family favorite that leaves everyone happy!
Frequently Asked Questions
- → Can I make this chili mac ahead of time?
Yes! You can prepare both the chili and mac and cheese components separately up to 2 days ahead. Store them in separate containers in the refrigerator. When ready to serve, combine them in a baking dish, top with cheese, and bake until hot throughout and the cheese is melted, approximately 20-25 minutes at 350°F.
- → What can I substitute for kidney beans?
You can easily substitute kidney beans with black beans, pinto beans, or even chickpeas depending on your preference. For a bean-free version, simply omit them or add more vegetables like corn or diced zucchini for additional texture and nutrition.
- → How spicy is this chili mac?
This chili mac has a mild to medium heat level from the chili seasoning and hot sauce. To make it milder, reduce or omit the hot sauce and use a mild chili seasoning. For more heat, add diced jalapeños, cayenne pepper, or increase the hot sauce to your preferred spice level.
- → Can I freeze leftover chili mac?
Yes, chili mac freezes well. Allow it to cool completely, then portion into airtight containers or freezer bags. Freeze for up to 3 months. Thaw overnight in the refrigerator and reheat in the microwave or in a covered dish in the oven at 350°F until heated through.
- → What sides pair well with chili mac?
Chili mac is hearty enough to serve as a complete meal, but it pairs nicely with simple sides like a green salad, steamed broccoli, or garlic bread. For casual gatherings, serve with corn chips, jalapeño cornbread, or coleslaw for added texture and flavor contrast.
- → Can I make this dish in one pot?
Yes, you can adapt this to a one-pot meal. After making the chili component, add uncooked macaroni and additional broth directly to the chili. Cover and simmer until pasta is tender, then stir in cheese until melted. This method creates a slightly different texture but reduces cleanup.
