Get ready for a creamy, cheesy delight! This Baked Cream Cheese Spaghetti Casserole is a comforting hug in a dish!

Step-by-Step Instructions

1. Preheat and Cook the Pasta
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
Cook the spaghetti according to package instructions until al dente. Drain and set aside.

2. Make the Cream Cheese Sauce
In a large mixing bowl, combine the softened cream cheese, sour cream, and milk. Whisk until smooth and creamy.
Stir in 1½ cups of the shredded cheddar cheese, garlic powder, onion powder, smoked paprika (if using), salt, and pepper. Mix until well combined.

3. Combine the Pasta and Sauce
Add the cooked spaghetti to the cream cheese mixture and toss until the pasta is evenly coated.
If using optional add-ins like cooked meat or veggies, gently fold them into the mixture.

4. Assemble the Casserole
Transfer the pasta mixture to the prepared baking dish, spreading it out evenly.
Sprinkle the remaining ½ cup of cheddar cheese and all of the mozzarella cheese over the top for a gooey, golden finish.
Optional: Sprinkle grated Parmesan cheese on top for an extra layer of flavor.

5. Bake Until Bubbly
Bake in the preheated oven for 25–30 minutes, or until the casserole is hot and bubbly, and the cheese topping is golden brown.
Optional: Broil for 2–3 minutes at the end of baking for an extra crispy cheese layer (watch closely to avoid burning).

6. Serve and Enjoy
Remove the casserole from the oven and let it cool for 5 minutes before serving.
Garnish with fresh parsley or green onions for a pop of color, if desired.
Serving Suggestions
Pair with a side salad or garlic bread for a complete meal.
Top with crushed red pepper flakes or hot sauce for a spicy kick.
Serve alongside roasted vegetables like asparagus or zucchini for added nutrition.

Pro Tips for Success

Use Fresh Ingredients: Freshly shredded cheese melts better than pre-shredded varieties, which often contain anti-caking agents.
Add Protein: Ground beef, Italian sausage, or shredded chicken make this dish even heartier.
Make Ahead: Assemble the casserole up to a day in advance, cover tightly, and refrigerate. Bake as directed, adding a few extra minutes if needed.
Freeze for Later: This casserole freezes beautifully! Assemble, freeze unbaked, and bake directly from frozen, adding 15–20 minutes to the cooking time.
