Ingredients for Baked Chili Mac Casserole

For the Pasta

12 ounces elbow macaroni: The classic pasta choice for chili mac. Its small shape holds onto the savory chili sauce, making every bite flavorful.

1 teaspoon salt: Used to season the pasta water. Properly salted water helps prevent bland macaroni.

For the Chili Mixture

1 pound ground beef: Provides the rich, savory foundation of the chili. Ground beef with moderate fat content adds plenty of flavor while remaining hearty.

1 can (15 ounces) kidney beans, drained and rinsed: Kidney beans add protein, texture, and classic chili flavor. Rinsing them also removes excess liquid from the can.

1 can (15 ounces) diced tomatoes with juices: Adds tomato flavor and moisture to the chili while helping create the sauce that coats the macaroni.

1 can (8 ounces) tomato sauce: Creates a smooth, rich base and helps bring all the ingredients together.

2 tablespoons tomato paste: Concentrated tomato paste adds depth, richness, and a more intense tomato flavor.

1 tablespoon chili powder: Provides the signature chili flavor and a gentle warmth.

1 teaspoon ground cumin: Adds earthy, slightly smoky notes that complement the beef and beans.

1 teaspoon paprika: Gives the chili a mild pepper flavor and beautiful color.

½ teaspoon dried oregano: Adds a subtle herbal note that balances the rich tomato and beef flavors.

½ teaspoon salt: Enhances the flavors of the chili. Adjust according to taste.

¼ teaspoon black pepper: Adds mild peppery warmth.

3 cloves garlic, minced: Fresh garlic gives the chili a savory aromatic base and makes the overall dish more flavorful.

1 small onion, diced: Adds sweetness and depth while creating a flavorful foundation for the beef.

¼ teaspoon cayenne pepper, optional: Use this if you enjoy a little extra heat. You can leave it out for a milder family-friendly casserole.

For the Cheese Topping

2 cups shredded cheddar cheese: The star of the topping. Cheddar melts beautifully and provides a rich, tangy, cheesy flavor.

½ cup shredded mozzarella, optional: Mozzarella adds extra meltiness and creates a wonderfully stretchy cheese topping.

2 tablespoons fresh parsley, chopped: Fresh parsley adds color and a light herbal freshness to the finished casserole.

How to Make Baked Chili Mac Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set it aside.

Preparing the baking dish first makes the final assembly quick and easy.

Step 2: Cook the Macaroni

Bring a large pot of water to a boil and season it with 1 teaspoon of salt.

Add the elbow macaroni and cook according to the package directions until just al dente.

Avoid overcooking the pasta because it will continue cooking in the oven. Once ready, drain the macaroni thoroughly and set it aside.

Step 3: Brown the Ground Beef

Place a large skillet over medium-high heat. Add the ground beef and cook until it is completely browned, breaking it apart with a spoon or spatula as it cooks.

If there is a significant amount of excess fat, carefully drain it.

Add the diced onion and cook for several minutes until the onion becomes soft and translucent.

Add the minced garlic and cook for about 30 seconds, stirring constantly until fragrant.

Step 4: Make the Chili

Add the kidney beans, diced tomatoes with their juices, tomato sauce, and tomato paste to the skillet.

Stir in the chili powder, cumin, paprika, oregano, salt, black pepper, and optional cayenne pepper.

Mix everything thoroughly.

Bring the mixture to a gentle simmer and cook uncovered for approximately 8–10 minutes, stirring occasionally.

This short simmering time allows the flavors to develop while reducing excess liquid and creating a thicker chili mixture.

Step 5: Combine the Chili and Macaroni

Add the drained macaroni directly to the skillet with the chili.

Gently stir until the pasta is evenly coated with the beef and tomato mixture.

Take a moment to make sure the beans, beef, sauce, and macaroni are distributed evenly. This ensures every serving contains a little bit of everything.

Step 6: Assemble the Casserole

Transfer the chili mac mixture to your prepared 9×13-inch baking dish.

Spread it evenly across the dish using a spatula or the back of a spoon.

Sprinkle the shredded cheddar cheese evenly over the entire surface.

If using mozzarella, sprinkle it over the cheddar for an extra-melty and golden cheese topping.

Step 7: Bake Until Bubbly and Golden

Place the uncovered casserole in the preheated oven.

Bake for approximately 15–20 minutes, or until the cheese is completely melted, bubbling around the edges, and lightly golden on top.

For an especially golden cheese crust, you can place the casserole under the broiler briefly at the end. Watch it carefully because cheese can brown quickly.

Step 8: Rest and Serve

Remove the casserole from the oven and let it rest for approximately 5 minutes.

This short resting period allows the sauce and cheese to settle, making the casserole easier to scoop and serve.

Finish with freshly chopped parsley and serve warm.

Pro Tips for the Best Chili Mac Casserole

Don't overcook the pasta. Cook the macaroni only until al dente. Overcooked pasta can become soft after baking.

Let the chili thicken. Simmering the chili uncovered for 8–10 minutes helps concentrate the flavors and prevents the finished casserole from becoming watery.

Shred your own cheese when possible. Freshly shredded cheddar generally melts more smoothly than many pre-shredded varieties.

Adjust the spice level. Leave out the cayenne for a mild casserole or add a little more if you prefer a spicy chili mac.

Don't skip the resting time. Allowing the casserole to rest for five minutes helps everything set while keeping the dish warm.

Taste before assembling. Once the chili has simmered, taste it and adjust the salt, pepper, or chili powder before adding the macaroni.

Use freshly cooked pasta. For the best texture, cook the macaroni shortly before assembling the casserole rather than letting it sit for a long time.

Easy Variations

One of the best things about chili mac casserole is how easy it is to customize.

Make It Spicier

Add extra cayenne pepper, crushed red pepper flakes, diced jalapeños, or your favorite hot sauce.

Add More Vegetables

You can add diced bell peppers, corn, mushrooms, or finely chopped zucchini to the chili mixture for extra flavor and texture.

Try Different Cheese

Cheddar is classic, but Monterey Jack, Colby Jack, pepper Jack, or a Mexican-style cheese blend can also work beautifully.

Make It Extra Meaty

For an even heartier casserole, add cooked bacon, sausage, or another pound of ground meat.

Make It Vegetarian

Replace the ground beef with additional beans, lentils, or a plant-based ground meat alternative.

What to Serve With Chili Mac Casserole

Because this casserole is already hearty and filling, simple sides are all you need.

Serve it with a fresh green salad for a lighter contrast to the rich chili and cheese.

Steamed broccoli or roasted vegetables also make an excellent side dish.

For a classic comfort-food meal, serve it with garlic bread or warm dinner rolls to soak up the flavorful sauce.

You can also add toppings such as:

Sour cream

Sliced green onions

Fresh parsley

Diced jalapeños

Avocado

Extra shredded cheddar

Hot sauce

How to Store Leftover Chili Mac Casserole

Allow leftover casserole to cool before transferring it to an airtight container.

Store it in the refrigerator for up to 3–4 days.

For longer storage, portion the cooled casserole into freezer-safe containers and freeze for up to 2–3 months for best quality.

When reheating refrigerated leftovers, microwave individual portions until heated through, or place the casserole in an oven-safe dish and warm it in a moderate oven until hot.

If the pasta seems dry after refrigeration, add a small splash of water or broth before reheating.

Frequently Asked Questions

Can I make Baked Chili Mac Casserole ahead of time?

Yes. You can prepare the chili and macaroni, assemble the casserole, cover it tightly, and refrigerate it before baking. When you're ready to cook, remove it from the refrigerator and bake until hot and the cheese is melted and bubbly. Because the casserole starts cold, it may require additional baking time.

Can I use a different type of pasta?

Absolutely. Elbow macaroni is traditional, but small shells, rotini, penne, or cavatappi can work well. Choose a pasta shape with plenty of grooves or curves to hold the chili sauce.

Can I make this casserole less spicy?

Yes. Simply omit the cayenne pepper and use a mild chili powder. You can also reduce the amount of chili powder if desired.

Why is my chili mac casserole watery?

Excess liquid can come from the tomatoes or from not simmering the chili long enough. Simmer the chili uncovered for 8–10 minutes before combining it with the macaroni to help reduce the liquid.

Can I freeze chili mac casserole?

Yes. Cool the casserole completely, portion it into freezer-safe containers, seal well, and freeze. Thaw overnight in the refrigerator before reheating for the best texture.
