- 2 cups marinara or your favorite tomato sauce: Brings bright acidity and a burst of comforting tomato flavor.
- 1 cup shredded mozzarella cheese: Known for its melty stretchiness, it gives the casserole a gooey, luscious top layer.
- 1 cup shredded cheddar cheese: Offers a sharp, tangy contrast that balances the creaminess beautifully.
- 1/2 cup grated Parmesan cheese: Adds a nutty, savory depth to the overall flavor profile.
- 1/2 cup sour cream (optional for extra creaminess): A little addition that can boost the smooth texture and add a gentle tang.
- 1 teaspoon garlic powder: Infuses the entire casserole with a subtle, aromatic punch.
- 1 teaspoon Italian seasoning: A fragrant herb blend that lifts and rounds out the dish’s flavor.
- Salt and pepper to taste: The essential seasoning to enhance and balance every bite.
- Fresh basil or parsley for garnish (optional): Adds a pop of color and a fresh herb note to finish off the dish.
How to Make Baked Cream Cheese Spaghetti Casserole Heaven
Step 1: Cook the Spaghetti
Start by boiling the spaghetti in salted water until it’s al dente, meaning it’s cooked but still has a slight bite to it. This texture is key so the pasta doesn’t become mushy when baked. Once cooked, drain the spaghetti thoroughly to avoid excess water weighing down the casserole.
Step 2: Prepare the Cream Cheese Mixture
In a large bowl, soften the cream cheese until it’s easily spreadable. Mix in the sour cream if you’re using it, then season with garlic powder, Italian seasoning, salt, and pepper. This mixture is what gives our casserole that indulgent, creamy quality and a subtle flavor boost.
Step 3: Combine Pasta and Sauce
Gently fold the cooked spaghetti into the cream cheese mixture, ensuring every strand gets coated. Then stir in the marinara sauce, creating a rich, tangy base that melds perfectly with the creamy cheese mixture.
Step 4: Layer the Cheese
Transfer the pasta mixture into a greased casserole dish. Sprinkle the shredded mozzarella, cheddar, and grated Parmesan evenly on top. These cheeses will melt and bubble in the oven, forming the golden, flavorful crust that makes this casserole stand out.
Step 5: Bake to Perfection
Pop your casserole into a preheated oven at 350°F (175°C) and bake for about 25-30 minutes. The top should be bubbling, golden brown, and irresistibly inviting. Allow it to cool for a few minutes before serving to let the flavors settle and the casserole firm up slightly.
How to Serve Baked Cream Cheese Spaghetti Casserole Heaven

Garnishes
Finishing touches like fresh basil or parsley really brighten up the dish and add a lovely herbal aroma. A sprinkle of extra Parmesan or even a drizzle of good-quality olive oil can elevate the flavors even more and make your casserole look picture-perfect.
Side Dishes
This casserole pairs wonderfully with crisp, fresh salads that offer some contrast to the rich, creamy pasta. Think a simple arugula salad with lemon vinaigrette or a crunchy Caesar salad. Roasted or steamed veggies like broccoli or asparagus can also make for a wholesome, balanced meal.
Creative Ways to Present
For a fun twist, serve individual portions of the casserole in small ramekins or even muffin tins to give a personal touch and great presentation. You can also experiment by layering in cooked sausage or sautéed mushrooms before baking to customize it further.
Make Ahead and Storage
Storing Leftovers
This casserole keeps wonderfully in the fridge for up to 3-4 days. Store leftovers in an airtight container to maintain moisture and prevent the pasta from drying out.
Freezing
Baked Cream Cheese Spaghetti Casserole Heaven freezes beautifully. Portion it out, wrap tightly, and place in freezer-safe containers for up to 3 months. It’s perfect for preparing meals ahead of time and enjoying comfort food whenever you need it.
Reheating
To reheat, thaw if frozen, then warm individual portions in the microwave or reheat the whole casserole in the oven at 350°F (175°C) until heated through. Cover with foil to keep moisture in and prevent the top from drying out.
FAQs
Can I use a different type of pasta?
Absolutely! While spaghetti works perfectly here, other pasta like penne, rigatoni, or rotini can hold the creamy sauce just as well. Just be sure to adjust cooking times based on the pasta type.
Is there a vegetarian version of this casserole?
The recipe is naturally vegetarian if you use marinara sauce without meat. For extra protein, you could add sautéed vegetables, mushrooms, or even some plant-based sausage alternatives.
Can I make this casserole dairy-free?
Making this casserole dairy-free is a bit tricky since cream cheese and cheeses are key players. However, you could try using plant-based cream cheese alternatives and dairy-free cheese options to recreate the creamy texture.
How spicy is this casserole?
This casserole is mild and comforting with no heat unless you add spicy ingredients yourself. It’s perfect for all palates, including kids and those sensitive to spice.
What’s the best way to reheat without drying it out?
Reheating covered with foil in the oven or covered in a microwave-safe dish is your best bet. Adding a splash of water or extra sauce before reheating can also help keep it moist.
Final Thoughts
This Baked Cream Cheese Spaghetti Casserole Heaven is a true game-changer for pasta lovers who adore creamy, cheesy comfort food.
