Ingredients

Scale

Pasta and Sauce Layers

  • 1 pound spaghetti
  • 1 (24 ounce) jar spaghetti sauce
  • 1 (10 ounce) can diced tomatoes and green chilies, undrained
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Meat and Vegetables

  • 1 pound ground beef
  • 1 medium onion, chopped
  • 1 green bell pepper, chopped

Cream Cheese Mixture

  • 8 ounces cream cheese, softened
  • 1/2 cup butter, melted
  • 1/2 cup grated Parmesan cheese
  • 1/4 cup milk
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Cheese Topping

  • 2 cups shredded mozzarella cheese

Instructions

  1. Brown the Beef: In a large skillet or Dutch oven, brown the ground beef over medium-high heat, breaking it up with a spoon until fully cooked. Drain off any excess grease to keep the dish from becoming too oily.
  2. Cook Vegetables: Add the chopped onion and green bell pepper to the skillet with the beef. Cook until softened, about 5-7 minutes, stirring occasionally to ensure even cooking.
  3. Add Tomatoes and Seasoning: Stir in the undrained diced tomatoes and green chilies, Italian seasoning, salt, and black pepper to the beef mixture.
  4. Simmer Sauce: Reduce heat to low, cover the skillet, and let the sauce simmer for at least 15 minutes to allow flavors to meld together. Stir occasionally to prevent sticking.
  5. Cook Spaghetti: While the meat sauce simmers, cook the spaghetti according to package directions until al dente. Once cooked, drain well to remove excess water.
  6. Make Cream Cheese Sauce: In a large bowl, combine the softened cream cheese and melted butter, stirring until smooth and blended.
  7. Add Parmesan and Milk: Stir in grated Parmesan cheese and milk to the cream cheese mixture until creamy and smooth.
  8. Season Cream Sauce: Add garlic powder, salt, and black pepper to the mixture. Taste and adjust seasonings if needed to achieve a balanced flavor.
  9. Combine Spaghetti and Cream Sauce: Add the cooked spaghetti to the bowl with the cream cheese mixture. Toss gently to evenly coat all noodles with the creamy sauce.
  10. First Layer in Dish: Pour half of the coated spaghetti into a greased 9×13 inch baking dish. Spread out evenly to form the first layer.
  11. Add Meat Sauce Layer: Spoon half of the simmered meat sauce over the spaghetti layer and spread evenly with a spoon.
  12. Sprinkle Mozzarella: Sprinkle half of the shredded mozzarella cheese over the meat sauce layer to add cheesy richness.
  13. Repeat Layers: Repeat the process by layering the remaining spaghetti mixture, then the remaining meat sauce, and finally top with the remaining mozzarella cheese.
  14. Bake the Casserole: Preheat the oven to 350°F (175°C). Bake the assembled casserole for 25-30 minutes until the cheese is melted, bubbly, and lightly golden brown on top, and the casserole is heated through.
  15. Rest and Serve: Let the casserole rest for 5-10 minutes after baking to set before slicing and serving. This helps the layers firm up for cleaner portions.

Notes

  • For a spicier kick, substitute diced tomatoes and green chilies with a spicy variety or add crushed red pepper flakes to the meat sauce.
  • You can prepare the meat sauce and cream cheese mixture in advance to save time on cooking day.
  • To make this dish lighter, use reduced-fat cream cheese and mozzarella cheese or omit the butter.
  • Leftovers store well in the refrigerator for up to 3 days and reheat nicely in the oven or microwave.
  • Feel free to add other vegetables like mushrooms or zucchini when cooking the meat sauce for additional flavor and nutrition.
