How to Make Chili Mac Casserole
Step 1: Boil the Pasta
Bring a pot of water to a boil and cook the elbow macaroni according to package directions until al dente. Drain and set aside.
Step 2: Cook the Beef and Onions
In a large skillet over medium heat, add ground beef and diced onion. Cook until the beef is no longer pink, about 5–7 minutes. Drain excess fat.
Step 3: Add Seasoning and Simmer
Return the skillet to heat. Add canned diced tomatoes, water, and taco seasoning to the beef mixture. Stir to combine and let it simmer for about 5 minutes, stirring occasionally.
Step 4: Combine Pasta with Meat Mixture
Add the cooked macaroni into the skillet with the beef mixture. Stir well to ensure all ingredients are combined evenly.

Spread half of the chili mac mixture in a greased 13×9 inch pan. Sprinkle one cup of shredded cheddar cheese over this layer. Top with the remaining meat mixture.
Step 6: Bake
Cover the baking dish with foil and place it in a preheated oven at 350°F (175°C). Bake for 30 minutes. Remove foil, sprinkle with remaining cup of cheese, then bake uncovered for another 10 minutes or until cheese is melted bubbly.
Enjoy your delicious homemade chili mac casserole! This dish not only fills bellies but also warms hearts with every cheesy bite.

Common Mistakes to Avoid
When making Chili Mac Casserole, it’s easy to overlook a few key steps. Here are some common mistakes to watch out for:
- Using the wrong pasta: Using a pasta that doesn’t hold sauce well can make your casserole watery. Stick with elbow macaroni for the best texture.
- Skipping the draining step: Not draining the fat from the beef can lead to a greasy casserole. Always drain excess fat after cooking the meat.
- Not seasoning enough: If you skip or skimp on taco seasoning, the dish may lack flavor. Make sure to use enough seasoning to enhance the taste.
- Overbaking: Baking for too long can dry out your casserole. Follow the recommended baking times closely and check for doneness.
- Forgetting to cover: Not covering the casserole with foil during baking can lead to uneven cooking. Always cover it initially to retain moisture.
