Ingredients

Scale

Protein:

  • 1 pound lean ground beef
  • 1 taco seasoning packet

Dairy:

  • 2 cups heavy cream
  • 1 cup shredded sharp cheddar cheese
  • 1 cup shredded Monterey jack cheese
  • ½ cup unsalted butter

Vegetables and Seasonings:

  • 16 ounces cooked spaghetti
  • 15 ounces tomato sauce
  • 10 ounces enchilada sauce
  • 1 onion
  • 1 green bell pepper
  • 4 garlic cloves
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • ½ teaspoon ground cumin
  • ½ teaspoon salt
  • ½ teaspoon pepper
  • Fresh cilantro

Instructions

  1. Preheat the oven to 350°F and coat a 9×13-inch baking dish with non-stick spray. Your prep work starts here.
  2. Brown 1 pound ground beef in a large skillet over medium-high heat for 5-7 minutes. Drain any excess fat.
  3. Sprinkle 1 packet taco seasoning, 1 teaspoon garlic powder, 1 teaspoon onion powder, ½ teaspoon cumin, ½ teaspoon salt, and ½ teaspoon pepper over the meat. Stir thoroughly.
  4. Add 1 small diced onion and 1 diced green bell pepper to the skillet. Cook until vegetables soften, about 3-5 minutes.
  5. Pour 15 ounces tomato sauce and 10 ounces enchilada sauce into the meat mixture. Simmer for 15 minutes on low heat.
  6. Melt ½ cup unsalted butter in a large pot over medium heat. Add 4 minced garlic cloves and saute for 30 seconds.
  7. Pour 2 cups heavy cream into the butter. Stir in 1 cup sharp cheddar and 1 cup Monterey jack cheese. Season with ½ teaspoon salt and pepper.
  8. Cook the cheese sauce until cheese melts completely and sauce thickens slightly.
  9. Toss 16 ounces cooked spaghetti into the creamy cheese mixture, ensuring pasta is evenly coated.
  10. Transfer the creamy spaghetti to the prepared baking dish. Spread the meat mixture evenly on top.
  11. Sprinkle 1 cup sharp cheddar and 1 cup Monterey jack cheese over the casserole.
  12. Bake uncovered at 350°F for 15 minutes until cheese is melted and bubbly.
  13. Allow the casserole to rest for 5 minutes after removing from the oven. Optionally garnish with fresh chopped cilantro before serving.

Notes

  • Check ground beef for even browning and drain excess fat to prevent a greasy casserole.
  • Taste the sauce before layering to ensure the seasoning matches your preference for spice and salt.
  • Let the casserole rest after baking so the cheesy layers can set and make serving easier.
  • For a lighter version, swap ground beef for ground turkey and use reduced-fat cheese options.
