Step‑by‑Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 baking dish.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the elbow macaroni 1–2 minutes less than the package directions (it will finish cooking in the casserole). Drain and set aside.
Step 3: Brown the Beef
In a large pot or Dutch oven over medium‑high heat, cook the ground beef and chopped onion until the beef is browned and the onion is soft (about 8–10 minutes). Drain excess fat. Add the minced garlic and cook for 1 minute until fragrant.
Step 4: Season the Beef
Stir in the chili seasoning and cook for 1 minute to bloom the spices.
Step 5: Build the Chili
Add the diced tomatoes (with juice), tomato sauce, rinsed beans, beef broth, and corn (if using). Stir to combine. Bring to a simmer, then reduce heat to medium‑low and cook for 10–15 minutes, stirring occasionally. Season with salt and pepper to taste.
Step 6: Combine with Pasta and Cheese
Add the cooked macaroni to the chili and stir to combine. Stir in 1 cup of shredded cheese until melted.
Step 7: Transfer to Baking Dish
Pour the chili mac mixture into the prepared baking dish and spread evenly. Sprinkle the remaining 1 cup of cheese over the top.
Step 8: Bake
Bake uncovered for 15–20 minutes, until the cheese is melted and bubbly and the edges are golden. For a browner top, switch to broil for the last 1–2 minutes (watch carefully).
Step 9: Rest and Serve
Let the casserole rest for 5–10 minutes before serving. Garnish with fresh parsley or green onions. Serve hot.
Pro Tips for the Best Chili Mac Casserole
- Cook Pasta Al Dente (or Slightly Under)
Overcooked pasta will become mushy when baked. Cook it 1–2 minutes less than the package directions.
- Use Freshly Shredded Cheese
Pre‑shredded cheese contains anti‑caking agents that can make the topping greasy and prevent smooth melting. Shred your own from a block.
- Let the Chili Simmer for Flavor
Don’t rush the chili step. Simmering for 10–15 minutes allows the flavors to meld.
- Add a Crunchy Topping (Optional)
Mix ½ cup panko breadcrumbs with 2 tbsp melted butter and sprinkle over the cheese before baking for an extra crispy crust.
- Make It Ahead
Assemble the casserole (without baking), cover, and refrigerate for up to 24 hours. Add 10–15 minutes to the baking time.
- Double for a Crowd
Use a larger roasting pan (11×15) and double all ingredients. Increase baking time to 25–30 minutes.
