Ingredient Notes & Details

Elbow Macaroni
Classic elbow pasta gives you that traditional chili mac texture. Cook it just until al dente so it doesn’t get mushy during baking. You can substitute shells or rotini if needed.

Ground Beef
Use 80/20 ground beef for the best flavor. Leaner beef works too — just be careful not to overcook it. Ground turkey is a lighter alternative.

Onion
Adds sweetness and depth. Yellow onion works best, but white onion is fine too.

Garlic
Fresh garlic adds bold flavor. Garlic powder can substitute in a pinch.

Tomato Sauce
Creates the rich base for this baked chili mac casserole. Choose a high-quality canned sauce for deeper flavor.

Diced Tomatoes
Adds texture and brightness. Fire-roasted tomatoes enhance the smoky flavor beautifully.

Chili Powder
The backbone of the chili flavor. Adjust to your spice preference.

Cumin
Adds warmth and depth, making this a true baked chili mac experience.

Paprika
Smoked paprika adds subtle smokiness.

Salt & Black Pepper
Essential for balancing flavors.

Cheddar Cheese
Sharp cheddar melts beautifully and adds bold flavor. Freshly shredded melts better than pre-shredded.

Monterey Jack Cheese
Adds extra creaminess and stretch.

Optional additions: kidney beans, black beans, jalapeños, or even a spoonful of sour cream stirred into the sauce.

Step-by-Step Instructions

Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.

Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the elbow macaroni until just al dente — about 1 minute less than package instructions. Drain and set aside.

Step 3: Brown the Beef
In a large skillet over medium heat, cook the ground beef until browned and fully cooked, about 6–8 minutes. Break it apart as it cooks. Drain excess grease if necessary.

Step 4: Add Aromatics
Stir in chopped onion and cook for 3–4 minutes until softened. Add minced garlic and cook for 30 seconds until fragrant.

Step 5: Build the Chili Base
Add tomato sauce, diced tomatoes, chili powder, cumin, paprika, salt, and pepper. Simmer for 8–10 minutes until slightly thickened. The mixture should be rich and saucy but not watery.

Step 6: Combine Pasta and Sauce
Stir the cooked pasta into the chili mixture until evenly coated.

Step 7: Layer the Cheese
Pour half of the pasta mixture into your baking dish. Sprinkle with half the cheddar and Monterey Jack. Add remaining pasta and top with remaining cheese.

Step 8: Bake Until Bubbly
Bake uncovered for 20–25 minutes, until the cheese is melted, bubbly, and slightly golden on top.

Step 9: Rest Before Serving
Let it rest for 5–10 minutes so it sets up slightly. This makes slicing and serving much easier.
