Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 350°F. Spray a 9×13-inch baking dish with nonstick spray and set it aside.
Step 2: Brown the Ground Beef
In a large skillet over medium-high heat, brown the ground beef until it is no longer pink. Use a slotted spoon to transfer the cooked beef to a paper towel-lined bowl to drain.
Step 3: Sauté Vegetables
Add the diced onion and bell pepper to the skillet with the leftover fat from the beef. Sauté for 2-3 minutes until softened. Then add the minced garlic and cook for an additional 30 seconds.
Step 4: Combine Ingredients
Return the cooked beef to the skillet. Stir in the drained diced tomatoes, tomato paste, kosher salt, Italian seasoning, ground black pepper, and Worcestershire sauce. Bring the mixture to a boil, then reduce the heat and let it simmer for 5 minutes. Remove from heat and set aside.
Step 5: Cook the Pasta
Meanwhile, cook the shell pasta according to package instructions. Once cooked, drain and transfer the pasta to a large bowl.
Step 6: Mix Pasta with Creamy Ingredients
Add the softened cream cheese, sour cream, and melted unsalted butter to the shell pasta. Mix well until the pasta is evenly coated with the creamy mixture.
Step 7: Layer the Casserole
Spread half of the creamy pasta mixture in the bottom of the prepared baking dish. Top this layer with half of the meat mixture. Repeat the layers with the remaining pasta and meat mixture.
Step 8: Add Cheese Topping
Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top of the casserole.
Step 9: Bake the Casserole
Bake the casserole uncovered for 25-30 minutes, or until heated through. If desired, broil the cheese for an additional 1-2 minutes to achieve a golden-brown crust.
Step 10: Garnish and Serve
Garnish with fresh parsley, if using, and let the casserole rest for 10 minutes before serving.

Cook techniques
Ground Beef Browning
Browning ground beef adds flavor and texture. Use a skillet over medium-high heat and ensure the meat is cooked until no longer pink. This step is essential for a rich base in your dish.
Sautéing Vegetables
Sautéing onions and bell peppers in the leftover fat from cooking meat enhances their flavors. Cook until softened and aromatic to create a delicious foundation for your mixture.
Simmering
Simmering allows flavors to meld together. After adding tomatoes and seasonings to the meat mixture, bring it to a boil, then reduce the heat and simmer for five minutes.
Cooking Pasta
To ensure the shell pasta is perfect, follow package instructions, making sure to boil it until al dente. Drain promptly to prevent it from becoming mushy.
Mixing Creamy Pasta
Combine softened cream cheese, sour cream, and melted butter with the pasta for a creamy texture. Mix thoroughly to ensure every piece of pasta is coated evenly.
Layering for Casserole
Layering the creamy pasta and meat mixture creates texture and flavor contrast. Spread half of each mixture in the baking dish, repeating for even distribution.
Baking
Baking the casserole at 350°F allows it to heat thoroughly and develop a cohesive texture. Broil for a few minutes for a beautifully melted and golden cheese topping.
Resting
Letting the casserole rest after baking for about 10 minutes helps set the layers and makes it easier to serve, enhancing the overall dining experience.
