Ingredients

Spaghetti: The base of the dish, spaghetti provides the classic pasta texture that holds the cream cheese and meat sauce well.

Ground Beef: Essential for a hearty and savory flavor, it makes the casserole filling and satisfying.

Cream Cheese: The secret to that velvety, creamy texture. It coats the noodles and adds a mild tang that balances the richness of the sauce.

Marinara Sauce: Brings in that tomatoey, herby base that ties everything together with the beef.

Onion & Garlic: These aromatics deepen the flavor of the meat sauce and build a savory foundation.

Olive Oil: Used to sauté the onions and garlic to release their flavor.

Mozzarella & Parmesan Cheese: These melt into a bubbly, golden topping that makes the casserole irresistible.

Salt, Pepper, and Italian Seasoning: Simple spices to round out and enhance the entire dish.

How to Make Baked Cream Cheese Spaghetti Casserole

Step 1: Cook the Pasta

Boil a large pot of salted water and cook the spaghetti until al dente. Drain and set aside, reserving a splash of the pasta water.

Step 2: Prepare the Meat Sauce

In a large skillet over medium heat, add olive oil and sauté chopped onions until soft. Add minced garlic and cook for another minute. Add the ground beef, breaking it up as it cooks. Once browned, stir in the marinara sauce and season with salt, pepper, and Italian seasoning. Simmer for 10 minutes.

Step 3: Mix Cream Cheese with Pasta

While the sauce simmers, mix the softened cream cheese into the hot pasta. Add a little reserved pasta water to help melt and coat the noodles evenly.

Step 4: Layer the Casserole

Preheat your oven to 350°F. In a greased baking dish, layer the cream cheese spaghetti first, then pour the meat sauce over the top. Spread it evenly.

Step 5: Add Cheese and Bake

Sprinkle mozzarella and Parmesan cheeses generously over the top. Bake uncovered for 25 to 30 minutes, or until the top is golden and bubbly.

Step 6: Let It Rest and Serve

Remove from the oven and let the casserole sit for 5 minutes before serving. This helps everything set and makes slicing easier.

Recipe Variations and Possible Substitutions

This casserole is versatile enough to tweak based on what you have or what you love. If you’re not into beef, swap it with ground turkey or Italian sausage for a new twist. You can even go meatless and load it up with sautéed mushrooms, spinach, or zucchini for a veggie-forward version.

Not a fan of cream cheese? Try using ricotta or a mix of sour cream and shredded mozzarella for a slightly different creaminess. And while spaghetti is traditional, feel free to use penne, rigatoni, or even fettuccine if that’s what’s in your pantry.

For a kick of spice, stir some red pepper flakes into the sauce. If you want a richer flavor, mix a bit of heavy cream into the marinara before layering.

Serving and Pairing Suggestions

Serve this baked cream cheese spaghetti casserole with a crisp green salad dressed in a light vinaigrette to cut through the richness. Garlic bread or a warm baguette is perfect for scooping up every last bit of sauce. I also love pairing it with roasted vegetables like broccoli or carrots for a full, balanced meal.

If you’re serving this for a dinner party, add a glass of red wine like Chianti or Merlot to elevate the experience. And for a fun touch, garnish with fresh chopped parsley or basil right before serving.

Storage and Reheating Tips

To store leftovers, let the casserole cool completely, then cover it tightly and refrigerate for up to 4 days. For longer storage, portion it out and freeze in airtight containers for up to 2 months.

To reheat, microwave individual portions until heated through, or warm the whole dish in a 325°F oven, covered with foil, for about 20 minutes. Add a splash of water or marinara if it looks a bit dry.
