This baked cream cheese spaghetti casserole brings together rich, creamy cheeses and savory marinara for a comforting meal that never disappoints. The golden edges and melty cheese topping add just the right amount of indulgence to simple spaghetti, making it a perfect dish for family dinners or casual get-togethers.

Ingredients

  • 12 ounces spaghetti: a sturdy pasta that holds up well in casseroles; choose a good quality brand for best texture
  • 8 ounces softened cream cheese: the key to the creamy texture; soften it fully to avoid lumps
  • One cup sour cream: adds tang and richness balancing the cream cheese's heaviness
  • One cup shredded mozzarella: melts beautifully for that stretchy, gooey cheese factor
  • Half a cup grated Parmesan: adds a sharp, nutty note that layers the cheese flavors
  • Two cups marinara or pasta sauce: use your favorite jarred variety or homemade sauce; quality impacts overall taste
  • Two cloves garlic minced: fresh garlic brings a fragrant depth; avoid pre-minced for a brighter flavor
  • One teaspoon Italian seasoning: a fragrant blend of herbs that ties the dish together
  • Half teaspoon black pepper: fresh cracked for a subtle bite
  • Half teaspoon salt: enhances all the flavors
  • Fresh basil or parsley for topping: adds a pop of color and fresh herbal aroma

Step-by-Step Instructions

Sauté the Garlic and Prepare Oven:
Preheat your oven to 350 degrees Fahrenheit. Mince the garlic finely to maximize flavor release when combined later on.
Cook the Spaghetti:
Boil a large pot of salted water and cook the spaghetti according to package directions until just al dente. Drain thoroughly so no excess water dilutes the sauce.
Mix the Creamy Sauce:
In a mixing bowl, combine the softened cream cheese and sour cream. Add the minced garlic, Italian seasoning, salt, and black pepper. Beat or stir vigorously until the mixture is completely smooth and homogeneous to avoid lumps.
Combine Spaghetti with Sauce:
Add the drained spaghetti to the creamy mixture. Toss gently but thoroughly until all strands are evenly coated in the rich sauce, ensuring every bite is flavorful.
Layer the Casserole:
Spread half of the coated spaghetti evenly in a greased baking dish. Pour half of the marinara sauce over this layer spreading it gently but completely.
Add Remaining Layers:
Top with the rest of the spaghetti and finish by pouring the remaining marinara sauce evenly over the top. This layering creates a beautiful blend of pasta and sauce in every slice.
Top with Cheese:
Sprinkle the shredded mozzarella along with the grated Parmesan over the casserole. This cheesy layer will melt down and brown beautifully in the oven.
Bake to Golden Perfection:
Place the dish in your preheated oven and bake for about 20 to 25 minutes until the cheese is melted and the edges are bubbling with golden brown color.
Garnish and Serve:
Remove from oven and let it rest for a few minutes. Sprinkle with fresh basil or parsley to brighten the dish and offer a fresh herbal note. Serve warm and enjoy the comforting richness.

Storage Tips

Leftovers keep beautifully in an airtight container in the refrigerator for up to four days. Reheat gently covered in the microwave or oven to preserve moisture and prevent drying out. For longer storage, freeze portions wrapped tightly to avoid freezer burn. Thaw overnight in the refrigerator before reheating.

Ingredient Substitutions

Feel free to swap sour cream with Greek yogurt for a lighter twist that still keeps creaminess. Use a shredded Italian blend cheese instead of mozzarella to add complexity. Fresh chopped herbs like oregano or thyme can replace Italian seasoning if on hand.

Serving Suggestions

Serve this casserole alongside a crisp green salad dressed with lemon vinaigrette to cut through the richness. Garlic bread or toasted baguette rounds make fantastic companions for soaking up any leftover cheesy sauce.

Cultural Context

This dish puts a comfort food spin on Italian-American classics by using cream cheese for a richer sauce. Baked pasta casseroles have roots in Mediterranean home cooking, where simple ingredients turn into hearty shared meals.
