Ingredients

For the Pasta

  • 8 oz (225g) spaghetti, broken in half
  • 1 tbsp olive oil (for greasing the baking dish)

For the Cream Cheese Sauce

  • 8 oz (225g) cream cheese, softened
  • ½ cup (120g) sour cream
  • 1 cup (240ml) marinara sauce
  • 1 tsp garlic powder
  • ½ tsp onion powder
  • ½ tsp dried oregano
  • ¼ tsp black pepper
  • ¼ tsp salt

For the Cheese Topping

  • ½ cup (50g) grated Parmesan cheese
  • 1½ cups (170g) shredded mozzarella cheese

(Optional: ½ lb cooked ground beef or Italian sausage for a meaty version)

Instructions

1. Cook the Pasta

  1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil.
  2. Cook spaghetti in salted boiling water until al dente (1–2 minutes less than package instructions). Drain and return to the pot.

2. Prepare the Sauce

  1. In a bowl, beat cream cheese and sour cream until smooth.
  2. Stir in marinara sauce, garlic powder, onion powder, oregano, pepper, and salt.

3. Assemble the Casserole

  1. Pour the sauce over the cooked spaghetti and toss to coat evenly.
  2. Transfer to the baking dish. Sprinkle with Parmesan, then top with mozzarella.

4. Bake to Perfection

  1. Bake uncovered for 20–25 minutes until the cheese is melted and bubbly.
  2. Broil for 1–2 minutes for a golden top (optional).

5. Serve

  • Let rest for 5 minutes before serving. Garnish with fresh basil or parsley if desired.

Why This Recipe Works

Creamy vs. Traditional Spaghetti Bake

✔ Cream cheese and sour cream add richness without heaviness.
✔ Marinara sauce balances the creaminess with tangy acidity.
✔ Double cheese layer (Parmesan + mozzarella) creates a flavorful crust.

Time-Saving Tips

  • Use pre-cooked pasta (leftover spaghetti works!).
  • Substitute jarred marinara for homemade.

Tips for Success

✔ Room-temperature cream cheese blends smoother.
✔ Undercook the pasta—it softens further while baking.
✔ For extra flavor, add ½ tsp red pepper flakes or 1 tbsp Italian seasoning.
✔ Storage: Refrigerate for 3–4 days or freeze for 1 month.

Serving Suggestions

  • With garlic bread and a crisp salad.
  • As a main dish for meatless Mondays.
  • For a hearty twist, mix in cooked spinach or mushrooms.

Conclusion

This Baked Cream Cheese Spaghetti Casserole is a decadent yet easy twist on classic pasta bakes. The creamy, cheesy, tomato-infused layers make it a guaranteed family favorite, while the minimal prep ensures it’s stress-free for busy cooks.

Perfect for cozy nights or feeding a crowd!

Variation: Swap spaghetti for penne or rotini, or add rotisserie chicken for extra protein.
