What You’ll Need to Make This Recipe

Note: The full ingredients list with exact measurements is in the recipe card below.

Pasta

Elbow macaroni is the classic choice here. It holds the chili sauce well and keeps the casserole feeling hearty without being heavy.

Ground Beef

Ground beef gives the chili its rich, savory base. Once browned with onion and garlic, it creates that classic comforting flavor.

Beans and Tomatoes

Kidney beans, diced tomatoes, tomato sauce, and tomato paste build the body of the chili. They make the sauce thick, hearty, and perfect for baking.

Spices

Chili powder, cumin, paprika, oregano, black pepper, and optional cayenne create a warm, smoky flavor that gives this casserole its chili-style character.

Cheese

Sharp cheddar adds bold flavor, while mozzarella gives that extra melty finish. Together, they create the kind of cheesy top that makes this casserole hard to resist.

How to Make Baked Chili Mac Casserole Step by Step

Step 1: Cook the pasta

Bring a large pot of salted water to a boil and cook the elbow macaroni until just al dente. You want the pasta to still have a little bite to it because it will continue cooking in the oven. Drain it and set it aside.

Kitchen Tip: Slightly undercooking the pasta at this stage helps keep the final casserole from turning too soft after baking.

Step 2: Brown the beef

In a large skillet over medium heat, cook the ground beef until browned. Drain any excess fat, then add the diced onion and cook until softened. Stir in the minced garlic and cook for about 30 seconds, just until fragrant.

Step 3: Build the chili

Add the kidney beans, diced tomatoes, tomato sauce, tomato paste, and all the spices. Stir everything together well and let it simmer uncovered for 8 to 10 minutes. This helps the chili thicken so your casserole won’t be watery.

Step 4: Combine and layer

Add the cooked macaroni to the chili mixture and stir until the pasta is fully coated. Transfer everything to a greased 9x13-inch baking dish and spread it evenly. Top generously with the shredded cheddar and mozzarella.

Step 5: Bake

Bake uncovered until the cheese is fully melted and just starting to turn golden around the edges. The casserole should be hot and bubbly.

Step 6: Let it rest

Allow the casserole to rest for about 5 minutes before serving. This helps everything settle so you get neat, hearty scoops instead of a runny casserole.

Expert Tips

Cook the pasta just to al dente so it keeps its texture after baking.
Let the chili simmer before baking to concentrate the flavor.
Use freshly shredded cheese if possible for the smoothest melt.
If you like it spicier, add the cayenne or a pinch of crushed red pepper.
Let it rest before serving so the casserole slices and scoops more cleanly.

How to Store and Reheat It

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave, or warm larger portions in the oven covered with foil until heated through.

You can also freeze this casserole. Let it cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

What to Serve With

Cornbread or garlic bread
A simple green salad
Steamed green beans
Sour cream, sliced green onions, or extra shredded cheese on top

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. You can assemble it ahead, cover it, and refrigerate it until you’re ready to bake. Add a few extra minutes to the baking time if it goes into the oven cold.

Can I use another type of pasta?

Absolutely. Small pasta shapes like rotini, shells, or penne work well too, as long as they’re cooked just to al dente.

Do I have to use kidney beans?

No. Black beans or pinto beans would also work well if that’s what you have on hand.

Can I make it spicier?

Yes. Add the cayenne, extra chili powder, or even diced jalapeños if you want more heat.

Can I leave out the mozzarella?

Yes. The cheddar alone will still give you a delicious cheesy topping, but mozzarella adds extra meltiness.
