 Ingredients

Here’s everything you’ll need to make this creamy, delicious casserole:

For the Pasta Base:

  • 12 ounces spaghetti (about 3/4 of a standard box)

  • 1 tablespoon olive oil

  • 1 teaspoon salt

For the Cream Cheese Mixture:

  • 8 ounces cream cheese, softened

  • 1/2 cup sour cream

  • 1/4 cup grated Parmesan cheese

  • 1 teaspoon garlic powder

  • 1/2 teaspoon onion powder

  • Salt and pepper to taste

For the Meat Sauce:

  • 1 pound ground beef (or Italian sausage for a spicier version)

  • 1 small onion, finely chopped

  • 2 cloves garlic, minced

  • 1 jar (24 ounces) marinara or spaghetti sauce (your favorite brand)

  • 1 teaspoon Italian seasoning

  • 1/2 teaspoon red pepper flakes (optional)

  • Salt and pepper to taste

For the Topping:

  • 1 1/2 cups shredded mozzarella cheese

  • 1/4 cup grated Parmesan cheese

  • Fresh parsley, chopped (for garnish)

 Instructions

Step 1: Cook the Spaghetti

  1. Bring a large pot of salted water to a boil.

  2. Add the spaghetti and cook until just al dente (usually about 1 minute less than the package directions).

  3. Drain the pasta and drizzle with olive oil to prevent sticking. Set aside.

Pro tip: Don’t overcook your pasta — it will continue to cook in the oven later!

Step 2: Make the Cream Cheese Layer

  1. In a medium mixing bowl, beat the softened cream cheese until smooth and creamy.

  2. Add the sour cream, Parmesan cheese, garlic powder, and onion powder.

  3. Mix until well combined.

  4. Taste and season with a pinch of salt and pepper.

This creamy layer is what gives the casserole its signature texture — rich and velvety, but not too heavy.

Step 3: Prepare the Meat Sauce

  1. In a large skillet, brown the ground beef (or sausage) over medium-high heat until fully cooked, about 7–8 minutes.

  2. Drain off excess fat.

  3. Add the chopped onion and minced garlic. Sauté for another 3–4 minutes until fragrant and softened.

  4. Stir in the marinara sauce, Italian seasoning, and red pepper flakes (if using).

  5. Simmer the sauce for 10 minutes, allowing the flavors to meld together.

  6. Taste and adjust seasoning with salt and pepper.

The sauce should be thick, hearty, and slightly tangy — the perfect contrast to the creamy cheese layer.

Step 4: Combine Pasta with Cream Cheese Mixture

  1. In a large mixing bowl, add the cooked spaghetti.

  2. Spoon in the cream cheese mixture and toss until the pasta is evenly coated.

  3. This creates the luscious, creamy pasta base that sets this casserole apart.

Step 5: Layer the Casserole

Now it’s time to assemble the magic:

  1. First layer: Spread half of the meat sauce evenly at the bottom of a greased 9×13-inch baking dish.

  2. Second layer: Add the creamy spaghetti mixture, spreading it out evenly.

  3. Third layer: Pour the remaining meat sauce over the top.

  4. Sprinkle the mozzarella and Parmesan cheese evenly over everything.

Optional: Add extra shredded cheese in the center for extra gooey goodness!

Step 6: Bake It

  1. Preheat your oven to 350°F (175°C).

  2. Cover the baking dish loosely with foil (to prevent the cheese from burning).

  3. Bake for 25 minutes.

  4. Remove the foil and bake for another 10–15 minutes, or until the cheese is melted and bubbly.

  5. Let the casserole rest for 10 minutes before serving.

 Serving Suggestions

This Baked Cream Cheese Spaghetti Casserole pairs wonderfully with:

  • Garlic Bread or Breadsticks – For soaking up all that cheesy sauce.

  • Steamed Vegetables or a Side Salad – Balances out the richness.

  • A glass of red wine or sparkling water – Complements the tomato and cheese flavors beautifully.

You can also sprinkle a bit of fresh basil, parsley, or red pepper flakes over each serving for a pop of freshness and color.

 Storage & Reheating

This dish is excellent for leftovers or meal prepping.

To Store:

  • Store in an airtight container in the refrigerator for up to 4 days.

To Freeze:

  • Assemble the casserole but don’t bake it.

  • Wrap tightly in plastic wrap and then foil.

  • Freeze for up to 3 months.

To Reheat:

  • If frozen, thaw overnight in the refrigerator.

  • Reheat in the oven at 350°F for 20–25 minutes until warmed through.

 Variations

Here are a few fun ways to customize your baked spaghetti casserole:

1. Meat Lovers’ Version

Use a mix of ground beef, sausage, and bacon for an ultra-hearty version.

2. Vegetarian Option

Skip the meat and load your sauce with mushrooms, bell peppers, zucchini, and spinach.

3. Spicy Kick

Add jalapeños or extra red pepper flakes to your meat sauce.

4. White Sauce Twist

Replace the tomato-based sauce with a creamy Alfredo sauce for a milder, buttery version.

5. Extra Cheese Layer

Add ricotta or cottage cheese between layers for extra creaminess.

 Cooking Tips

  1. Soften the cream cheese completely before mixing to avoid lumps.

  2. Use high-quality marinara sauce — it makes a big difference in flavor.

  3. Don’t overcook the pasta; it should be slightly firm before baking.

  4. Let it rest before cutting — this helps the layers hold together beautifully.

  5. Add shredded cheddar or provolone for a more complex cheese flavor.
