• Yield: 1 casserole
• Dietary Type: Comfort Food

Ingredients

• 1 lb ground beef
• 2 tablespoons minced fresh garlic
• 1 onion, chopped
• 1 green bell pepper, chopped
• 1-2 teaspoon dried chili pepper flakes (optional or to taste, add in if you like spicy!)
• 2 (1 ounce) packages taco seasoning mix (you can use 1 package if desired, or use a single or double recipe of my Kittencal’s Taco Seasoning Mix)
• 1/3 cup grated parmesan cheese (optional)
• 8 slices bacon (cooked till very crisp and chopped)
• 1 (8 ounce) can tomato sauce
• 2 (10 ounce) cans tomato soup
• 1-2 tablespoon brown sugar (optional)
• Seasoning salt (can use white salt)
• Pepper
• 3 cups cooked macaroni (can use less, cook the macaroni to JUST firm-tender)
• 4 cups shredded Tex-Mex cheese, divided (or to taste or cheddar cheese or mozzarella cheese)

Equipment Needed

• Large Skillet
• 13 x 9-inch Casserole Dish

Instructions

1. Preheat your culinary canvas. In a large skillet, over medium-high heat, brown the ground beef with the dried chili flakes (if using), chopped onion, minced garlic, and chopped green pepper. This browning process is crucial for developing deep, savory flavors, so ensure the beef is well browned, taking approximately 10-12 minutes. Remember to drain any excess fat to prevent a greasy casserole.

2. Spice things up. Add in the taco seasoning mix along with the Parmesan cheese (if using). Mix to thoroughly combine and cook for 1 minute, allowing the spices to bloom and release their aromatic oils.

3. Build the flavor profile. Introduce the cooked and chopped bacon, the tomato sauce, the two cans of tomato soup, and the brown sugar (if using) to the skillet. Simmer this mixture for 30-40 minutes, stirring occasionally to prevent sticking and allow the flavors to meld beautifully.

4. Season to perfection. Taste the simmering sauce and season with seasoning salt and pepper to your liking. Remember, you can always add more seasoning, but you can’t take it away!

5. Cheese it up. Mix in 2 cups of the shredded Tex-Mex or cheddar cheese into the sauce until melted and creamy. This will add richness and bind the casserole together.

6. Macaroni magic. Add in the cooked macaroni pasta to the skillet and mix to thoroughly combine, ensuring every strand is coated in the flavorful sauce.

7. Prepare for baking. Set the oven to 350 degrees F (175 degrees C). While the oven preheats, grease a 13 x 9-inch casserole dish (or larger) to prevent sticking.

8. Assemble the casserole. Transfer the macaroni mixture from the skillet to the prepared casserole dish, spreading it evenly.

9. Top with cheesy goodness. Sprinkle the top with the optional grated Parmesan cheese, followed by the remaining 2 cups (or more, to taste) of grated Tex-Mex or cheddar cheese. Be generous – the cheese topping is what makes this casserole truly irresistible.

10. Bake to golden perfection. Bake uncovered for approximately 20 minutes, or until the casserole is bubbly around the edges and the cheese on top is melted and beautifully golden brown.

11. Let rest briefly before serving. This allows the casserole to set slightly and makes it easier to serve.

Expert Tips & Tricks

• Don’t overcook the macaroni. The pasta should be cooked just to firm-tender, as it will continue to cook in the oven. Overcooked pasta will become mushy in the casserole.
• Brown the beef thoroughly. This step is crucial for developing deep flavor. Don’t rush it!
• Adjust the spices to your liking. If you prefer a spicier casserole, add more chili flakes or use a spicier taco seasoning.
• Use high-quality cheese. The better the cheese, the better the flavor of the casserole.
• Make it ahead of time. This casserole can be assembled up to 24 hours in advance. Cover tightly with plastic wrap and refrigerate. Add about 10-15 minutes to the baking time if baking from cold.

Serving & Storage Suggestions

This Mexi Ground Beef Chili Macaroni Casserole is best served warm, straight from the oven. Garnish with a dollop of sour cream or plain Greek yogurt, a sprinkle of chopped cilantro, or a few sliced green onions for an extra touch of freshness.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, microwave individual portions until heated through, or reheat the entire casserole in a preheated oven at 350 degrees F (175 degrees C) until warmed through.

Freezing is also an option. Allow the casserole to cool completely before wrapping it tightly in plastic wrap and then in foil. Freeze for up to 2-3 months. Thaw in the refrigerator overnight before reheating.
