What Is Chili Macaroni Casserole?
At its heart, this dish is a hearty, baked pasta casserole that combines two beloved comfort foods – chili and macaroni and cheese – into one satisfying meal. The base is a savory mixture of ground beef, onions, garlic, chili powder, diced tomatoes, and tomato sauce, simmered until flavorful, then combined with cooked elbow macaroni. The whole thing is topped with a generous layer of cheese and baked until hot and bubbly. The result is a dish that’s rich, hearty, and deeply satisfying.
This recipe falls into the category of “emergency dinners” and “crowd‑pleasing casseroles” – the kind of meal that requires almost no effort but delivers big flavor. It’s perfect for busy weeknights, potlucks, or any time you need a comforting meal that feeds a crowd. The combination of chili and macaroni is a classic for a reason – it’s affordable, filling, and absolutely delicious.
What makes this version especially brilliant is the one‑dish baking method. Everything comes together in a single skillet before being transferred to a baking dish, making cleanup a breeze. The cheese topping melts into a golden, bubbly crust that’s the perfect finishing touch.

Ingredients for Chili Macaroni Casserole
This recipe uses simple, flavorful ingredients that come together beautifully. Here’s what you’ll need:
Core Ingredients
1 pound elbow macaroni (or any short pasta)
2 pounds ground beef (80/20 for best flavor)
1 large onion, diced
4 cloves garlic, minced
1 can (28 oz) crushed tomatoes
1 can (15 oz) tomato sauce
2 tablespoons chili powder
1 tablespoon ground cumin
1 teaspoon paprika
1 teaspoon onion powder
½ teaspoon cayenne pepper (optional, for heat)
1 teaspoon salt
½ teaspoon black pepper
2 cups shredded cheddar cheese (or a blend)
Optional Add‑Ins
- 1 can (15 oz) kidney beans, drained and rinsed
- 1 can (4 oz) diced green chilies
- 1 cup frozen corn kernels
- ½ cup diced bell peppers
- Extra cheese for topping (about ½ cup)
Ingredient Notes and Substitutions
Ground Beef: 80/20 ground beef provides the best flavor and juiciness. You can substitute with ground turkey, chicken, or a plant‑based ground meat alternative.
Pasta: Elbow macaroni is classic, but any short pasta – shells, rotini, penne – works beautifully.
Tomatoes: Crushed tomatoes give a rich, thick sauce. You can substitute with diced tomatoes (with their juice) for a chunkier texture.
Chili Powder and Cumin: These are the essential spices for that classic chili flavor. Adjust the amount to your preference – add more for extra heat, or reduce for a milder version.
Cheese: Cheddar is classic, but a blend of cheddar and Monterey Jack is even better. For a spicy kick, use pepper jack.
Step‑by‑Step Instructions
Follow these detailed steps to create a flawless Chili Macaroni Casserole every single time. The process is straightforward, and the results are spectacular.
1. Cook the Pasta
Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Cook the elbow macaroni according to package instructions until al dente (about 6–8 minutes). Drain well and set aside.
2. Brown the Ground Beef
In a large skillet or Dutch oven over medium‑high heat, cook the ground beef, breaking it apart with a wooden spoon, until browned and no longer pink – about 6–8 minutes. Drain any excess fat, leaving about 1 tablespoon in the pan.
3. Sauté the Aromatics
Add the diced onion to the skillet with the beef and cook until softened – about 3–4 minutes. Add the minced garlic and cook for another minute until fragrant.
4. Build the Chili Sauce
Add the crushed tomatoes, tomato sauce, chili powder, cumin, paprika, onion powder, cayenne (if using), salt, and pepper to the skillet. Stir to combine. If you’re using any optional add‑ins (kidney beans, green chilies, corn, or bell peppers), add them now. Bring the sauce to a simmer and let it cook for 5–7 minutes to allow the flavors to meld.
5. Combine with Pasta
Add the cooked macaroni to the skillet and stir until it’s evenly coated in the chili sauce. Transfer the mixture to a greased 9×13‑inch baking dish.
6. Top with Cheese and Bake
Sprinkle the shredded cheddar cheese evenly over the top of the casserole. Bake, uncovered, for 20–25 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
7. Rest and Serve
Remove from the oven and let the casserole rest for 5–10 minutes before serving. This allows the casserole to set and makes it easier to serve. Garnish with fresh parsley or green onions if desired.
Expert Tips for the Perfect Chili Mac
This recipe is simple, but a few expert tricks will elevate it to perfection. Here’s what I’ve learned from making this dish countless times:
Don’t overcook the pasta – cook it just until al dente, as it will continue to absorb liquid in the oven.
Drain the beef well – excess fat can make the casserole greasy. Drain thoroughly.
Let it rest – resting the casserole for 5–10 minutes allows it to set and makes for cleaner servings.
Make it ahead – assemble the casserole (without baking) and refrigerate for up to 24 hours. Add 10–15 minutes to the baking time.
Freeze for later – this casserole freezes beautifully. Assemble, cover tightly, and freeze for up to 2 months. Thaw overnight and bake as directed.
Add extra cheese – for an even cheesier dish, stir 1 cup of cheese into the pasta mixture before baking.
Adjust the heat – for a milder version, reduce or omit the cayenne and use mild chili powder. For a spicier version, add extra chili powder, cayenne, or a diced jalapeño.
Delicious Variations
One of the best things about this recipe is how easily it adapts to different tastes and cravings. Here are some of my favorite ways to switch it up:
Loaded Chili Mac Casserole
Top the casserole with crushed tortilla chips, diced avocado, sour cream, and fresh cilantro before serving. This turns it into a loaded chili mac that’s perfect for game day.
Bacon Chili Mac
Add 6 slices of crispy cooked bacon (crumbled) to the beef mixture. The smoky bacon adds an extra layer of flavor.
Vegetarian Chili Mac
Replace the ground beef with 1½ cups of cooked lentils or plant‑based crumbles. Add extra beans and vegetables for a hearty vegetarian version.
White Chicken Chili Mac
Use shredded chicken instead of beef, and replace the tomato sauce with cream of chicken soup and chicken broth. Use white beans and green chilies for a creamy, Southwestern version.
Tex‑Mex Chili Mac
Add 1 can of diced green chilies, 1 cup of corn, and extra cumin and cilantro. Top with pepper jack cheese for a spicy, Tex‑Mex twist.
Slow Cooker Chili Mac
Brown the beef and onions on the stovetop, then transfer everything (except the pasta and cheese) to a slow cooker. Cook on LOW for 4–5 hours or HIGH for 2–3 hours. Stir in cooked pasta and cheese before serving.
Serving Suggestions
This versatile casserole can be served in a variety of ways, making it perfect for any occasion:
With a side salad – a crisp green salad with a tangy vinaigrette cuts through the richness.
With cornbread – a slice of warm cornbread is the perfect accompaniment.
With sour cream and salsa – for a Southwestern flair.
With garlic bread – perfect for sopping up any extra sauce.
For game day – serve with chips and dip for a complete spread.
For meal prep – portion out individual servings for easy lunches all week.
With pickled jalapeños – add a pop of heat and tang.
Storage and Reheating Guidelines
This dish stores beautifully, making it a fantastic make‑ahead option.
Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors deepen and intensify overnight – it’s even better the next day.
Reheating: For the best texture, reheat in a 350°F oven for 15–20 minutes until warmed through. You can also microwave individual portions for 2–3 minutes.
Freezing: This casserole freezes beautifully. Place it in a freezer‑safe container, leaving a little headspace, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat in the oven.
Pro tip: If the casserole seems dry upon reheating, add a splash of broth or tomato sauce to restore moisture.
