Ingredients

  • 1 pound lean ground beef
  • 1 yellow onion diced
  • 1 green bell pepper diced, seeds removed
  • 28 ounce Red Enchilada Sauce mild
  • 1 tablespoon granulated garlic
  • 1 teaspoon ground cumin
  • 1 pound spaghetti cooked half- way, drained (it will finish cooking in the oven)
  • 1 cup heavy cream or milk
  • 4 cups cheddar cheese shredded, divided use
  • 5 ounces queso fresco
  • ½ cup sliced olives
  • cup salsa plus more for serving
  • 2 tablespoons fresh cilantro chopped for garnish
  • sour cream for serving

Instructions

  • Preheat oven to 400°.
  • In a large skillet over medium-high heat, cook the 1 pound lean ground beef until browned.
  • Add the diced onion and bell peppers to the skillet and cook until softened, about 3-4 minutes. Drain excess grease if needed.
  • Stir in the 28 ounce Red Enchilada Sauce, 1 tablespoon granulated garlic, and 1 teaspoon ground cumin. Simmer for a few minutes to allow the flavors to meld.
  • Add the cooked spaghetti noodles to the skillet and toss to coat in the sauce. Pour the mixture into a greased 9×13 casserole dish.
  • In the same skillet, add the 1 cup heavy cream, 2 cups of cheddar cheese, and 5 ounces queso fresco. Whisk over medium heat until the cheese is melted and smooth.
  • Pour the creamy cheese sauce over the spaghetti mixture, stirring gently to combine.
  • Sprinkle the remaining cheddar cheese over the top, then add 1/2 cup sliced olives and 1/3 cup salsa. Bake at 400°F for 15- 20 minutes, or until bubbly and heated through.
  • Top with fresh cilantro and serve with sour cream and salsa.

Notes

  • Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • Reheating: Reheat in a non-stick skillet over medium heat, stirring occasionally until heated through or in a covered baking dish at 325°F until warmed through.
  • Make-Ahead Tip: Assemble the casserole in advance and refrigerate until ready to bake. Add 5-10 minutes to the baking time if cooking from cold.
