Ingredients You’ll Need

This recipe calls for straightforward ingredients that work harmoniously to create a rich and flavorful casserole. Each item is essential, from the creamy base to the perfectly seasoned tomato sauce, giving you a balance of comfort and zest in every bite.

• 1 lb spaghetti: The backbone of the dish, perfectly cooked to tender al dente for the ideal bite.
• 8 oz cream cheese, softened: Adds luscious creaminess that makes the sauce velvety smooth.
• 1 can (15 oz) tomato sauce: Provides a robust tomato flavor that blends beautifully with the cream cheese.
• 1 can (14.5 oz) diced tomatoes, drained: Adds texture and a fresh burst of tomato in every mouthful.
• 1/2 cup heavy cream (or milk): Enriches the sauce, making it decadently creamy while balancing acidity.
• 1 tablespoon Italian seasoning: A fragrant mix that brings herbs like oregano and basil to lift the flavor.
• 1 teaspoon garlic powder: Infuses a subtle garlicky depth without overpowering.
• 1 teaspoon onion powder: Enhances the savory profile with a mild sweetness.
• 1/2 teaspoon crushed red pepper flakes (optional): Adds just the right kick of heat for those who love a bit of spice.
• 2 cups shredded mozzarella cheese: Melts to a gooey, stretchy topping that keeps every bite comforting.
• 1/2 cup grated Parmesan cheese: Provides a sharp, nutty contrast that elevates the cheesy topping.
• 1/2 lb ground beef or sausage (optional): Boosts protein and adds a savory richness if you want to make it heartier.
• Salt and pepper to taste: Essential seasonings to brighten and balance flavors.
• Fresh basil or parsley for garnish (optional): Fresh herbs add color and a burst of fresh aroma that complements the creamy casserole.

How to Make Baked Cream Cheese Spaghetti Casserole Recipe

Step 1: Cook the Spaghetti

The first step is all about perfect pasta. Boil the spaghetti according to the package directions until just al dente — tender yet with a little bite. This is crucial because it will continue to cook in the oven. Once done, drain and set aside while you prepare the creamy sauce.

Step 2: Prepare the Cream Cheese Sauce

In a medium saucepan, bring together the softened cream cheese, heavy cream, tomato sauce, and diced tomatoes along with garlic powder, onion powder, Italian seasoning, and optional crushed red pepper flakes. Warm the mixture over medium heat, stirring often until the cream cheese melts fully and the sauce is luxuriously smooth. Season with salt and pepper to your liking.

Step 3: Brown the Meat (Optional)

If you decide to add ground beef or sausage, brown it in a skillet separately. Drain excess fat if necessary, then stir it right into the creamy sauce. This step layers in heartiness and extra savory notes that make the casserole even more satisfying.

Step 4: Combine and Assemble

In a large mixing bowl, toss the cooked spaghetti with the cream cheese sauce to coat every strand beautifully. Transfer this creamy noodle mixture into a greased 9×13-inch baking dish, spreading it evenly to prepare for the cheese topping.

Step 5: Layer the Cheese and Bake

Sprinkle shredded mozzarella and grated Parmesan evenly over the top—you want plenty of cheesy goodness. Bake the casserole in a preheated 350°F oven for 20 to 25 minutes, until the cheese melts, bubbles, and turns a gorgeous golden color. For a deeper, caramelized crust, you can broil it for an additional 2 to 3 minutes at the end.

Step 6: Rest and Garnish

Once out of the oven, give the casserole 5 to 10 minutes to set so it holds together nicely when served. Garnish with fresh basil or parsley for a bright finishing touch that adds freshness and a pop of color.

Garnishes

Fresh herbs like basil or parsley not only brighten the dish visually but also add a lovely herbal aroma that balances the richness of the casserole. A sprinkle of extra Parmesan or even a drizzle of olive oil can elevate the final presentation and flavor.

Side Dishes

This casserole pairs wonderfully with crisp green salads, steamed or roasted vegetables, or garlic bread to soak up any extra sauce. Think bright, fresh sides to contrast the creamy, cheesy main event. It’s a classic combo that turns a simple meal into a well-rounded spread.

Creative Ways to Present

For a fun twist, serve the Baked Cream Cheese Spaghetti Casserole Recipe in individual ramekins for personal-sized portions.

Make Ahead and Storage

Storing Leftovers

Leftover casserole keeps well in the refrigerator for up to 3 to 4 days. Store it in an airtight container to maintain freshness and moisture. It tastes just as satisfying when reheated gently.

Freezing

This casserole freezes beautifully so you can enjoy it later without stress. Portion it into freezer-safe containers or cover the entire dish tightly with foil and plastic wrap. It will keep well in the freezer for up to 2 months.

Reheating

Thaw frozen casserole overnight in the fridge if possible. Reheat in the oven at 350°F until warmed through to retain the cheesy melt and prevent sogginess. You can also microwave individual servings for convenience, though baking gives the best texture.

FAQs

Can I make this casserole vegetarian?

Absolutely! Simply omit the ground beef or sausage, and you can even add sautéed mushrooms or roasted vegetables to keep it hearty while staying meat-free.

What can I substitute for cream cheese?

If you don’t have cream cheese, you can try using ricotta mixed with a bit of sour cream or Greek yogurt for a tangy twist, though the texture will differ slightly.

Is it okay to use milk instead of heavy cream?

Yes, using milk makes the dish a bit lighter and still creamy. Just keep in mind that heavy cream adds richness and indulgence that milk can only partially imitate.

Can I prepare the casserole a day ahead?

You can assemble the casserole and refrigerate it before baking. When ready, bake it directly from the fridge, just add extra baking time until it’s heated through and bubbly.

How spicy does the crushed red pepper flakes make it?

The flakes add a gentle warmth, not overpowering heat. You can adjust or omit them entirely depending on your spice tolerance or family preferences.
