Ingredients
  

  • 12 oz spaghetti
  • 1 tablespoon olive oil
  • 1 lb ground beef or ground turkey
  • 1 packet taco seasoning or 2 tablespoons homemade
  • 1 cup salsa mild, medium, or spicy
  • ½ cup sour cream
  • ¼ cup cream cheese softened
  • ¼ cup milk
  • 2 cups shredded cheddar cheese
  • 1 cup shredded Monterey Jack or Mexican blend cheese
  • Salt and pepper to taste
  • Optional toppings: sliced green onions chopped cilantro, diced tomatoes, crushed tortilla chips

Instructions
 

  • Cook the spaghetti:
  • Bring a large pot of salted water to a boil and cook the spaghetti according to package directions. Drain and set aside.
  • Brown the beef:
  • While the pasta cooks, heat olive oil in a large skillet over medium heat. Add ground beef and cook until browned and no longer pink. Drain excess fat if needed.
  • Season and simmer:
  • Stir in taco seasoning and salsa. Simmer for 2–3 minutes to let the flavors combine. Remove from heat.
  • Make the creamy mixture:
  • In a large mixing bowl, combine sour cream, cream cheese, milk, and a pinch of salt and pepper. Stir until smooth. Add in the cooked spaghetti and toss to coat.
  • Assemble the casserole:
  • Preheat oven to 375°F (190°C). In a greased 9x13-inch baking dish, layer half the creamy spaghetti, half the beef mixture, and 1 cup cheddar cheese. Repeat the layers, then top with Monterey Jack cheese.
  • Bake until bubbly:
  • Cover loosely with foil and bake for 20 minutes. Remove the foil and bake for another 5–10 minutes until the cheese is fully melted and bubbly.
  • Garnish and serve:
  • Let rest for 5 minutes before serving. Top with your favorite taco toppings like green onions, cilantro, or crushed chips!

Notes

  • You can swap ground beef for ground turkey or even black beans for a vegetarian twist.
  • Add sautéed bell peppers, corn, or jalapeños for extra texture and flavor.
  • This casserole freezes well—assemble ahead, freeze, and bake when ready.
  • Great for meal prep: portion into containers and refrigerate for up to 4 days.
