Step‑by‑Step Instructions for Baked Cream Cheese Spaghetti Casserole
Step 1: Cook the Spaghetti
Begin by boiling a large pot of salted water over high heat. Add spaghetti and cook until al dente according to package instructions, usually around 8-10 minutes. Drain the pasta in a colander and give it a quick rinse to stop the cooking process. Set the spaghetti aside while you prepare the creamy filling for the Baked Cream Cheese Spaghetti Casserole.
Step 2: Prepare the Cream Cheese Sauce
In a spacious mixing bowl, blend the softened cream cheese until smooth and creamy using a spatula or hand mixer. Then, incorporate the marinara sauce, garlic powder, Italian seasoning, salt, and pepper, mixing thoroughly until well combined. If you’d like to add extra creaminess, stir in the optional sour cream. This creamy mixture will envelop the spaghetti beautifully.
Step 3: Combine Pasta and Sauce
Carefully add the cooked spaghetti to the cream cheese sauce, tossing gently until every strand is evenly coated. Make sure each piece of pasta is enveloped in the creamy goodness to ensure a rich flavor in every bite of your Baked Cream Cheese Spaghetti Casserole. This step gives the pasta a luxuriously creamy texture you’ll love.
Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C) to get it ready for baking. While the oven warms up, lightly grease a 9×13-inch baking dish. Pour the spaghetti mixture into the dish, spreading it out evenly. This helps ensure every portion gets the perfect amount of sauce and cheesy goodness. Now, sprinkle the shredded mozzarella, cheddar, and parmesan cheese generously over the top.
Step 5: Bake to Perfection
Place the baking dish in the preheated oven, allowing your Baked Cream Cheese Spaghetti Casserole to bake for 25-30 minutes. Keep an eye on it as it cooks; you’ll know it’s done when the cheese is melted and bubbling, with a lovely golden brown crust on top. The aroma wafting through your kitchen will be irresistible!
Step 6: Garnish and Serve
Once baked, remove the casserole from the oven and let it rest for about 5 minutes. This allows the flavors to settle and makes serving easier. If desired, garnish with fresh basil or parsley for an added pop of color and freshness. Scoop servings onto plates, and enjoy the creamy, comforting delight of your Baked Cream Cheese Spaghetti Casserole!

Expert Tips for Baked Cream Cheese Spaghetti Casserole
-
Soften Cream Cheese: Ensure the cream cheese is at room temperature for easy mixing. Cold cream cheese can create lumps and an unappetizing texture in your casserole.
-
Cook Al Dente: Boil the spaghetti just until al dente to prevent it from becoming mushy after baking. The pasta will continue cooking in the oven, so it’s best to slightly undercook it.
-
Taste Before Baking: Always taste the cream cheese sauce mixture before adding it to the pasta. This way, you can adjust seasoning levels to create the perfect Baked Cream Cheese Spaghetti Casserole.
-
Cheese Variations: Experiment with different cheeses for your topping. Mixing a sharp cheddar with creamy mozzarella creates a delightful flavor profile and texture contrast.
-
Avoid Overbaking: Keep an eye on your casserole towards the end of baking to prevent burning the top. It should be bubbly and golden brown, but not overly dark.
-
Make it Colorful: Add vegetables like spinach or bell peppers for extra nutrition and vibrant colors. These additions complement the creamy sauce beautifully while enhancing the overall dish.
Make Ahead Options

Simply follow the recipe through the assembly step, then cover and refrigerate the unbaked casserole. To maintain quality, ensure it’s tightly wrapped to prevent the pasta from drying out. When you’re ready to serve, preheat your oven and bake it straight from the fridge for 30-35 minutes until bubbly and golden. This strategy allows for a quick and satisfying meal that will taste just as delightful as if it were freshly made, giving you the comfort of home cooking with minimal effort!
