Ingredients for baked cream cheese spaghetti casserole recipe
Ready to make the creamiest pasta casserole?
- 1 pound spaghetti
- 8 ounces cream cheese (softened)
- ½ cup sour cream
- ¼ cup mayonnaise
- ½ cup whole milk
- 2 large eggs (beaten, optional)
- 1 cup shredded sharp cheddar cheese
- ½ cup grated Parmesan cheese (divided)
- 2 tablespoons butter (divided)
- ½ cup finely diced yellow onion
- 2 cloves garlic (minced)
- ½ cup breadcrumbs or crushed Ritz crackers
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon smoked paprika
- 1 teaspoon dried parsley
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Fresh parsley for garnish (optional)
Room temperature cream cheese is essential—cold cheese creates lumps that won’t smooth out. Sharp cheddar brings more depth than mild varieties.
Ritz crackers make the best topping since their buttery saltiness melts into golden perfection. Regular breadcrumbs work too with extra butter.
Step-by-step instructions
1. Preheat oven to 350°F and grease a 9×13-inch baking dish with nonstick spray or butter.
2. Cook spaghetti in salted boiling water until al dente (8-10 minutes). Drain thoroughly and rinse briefly with cool water to stop cooking, then set aside.
3. Sauté aromatics by melting 1 tablespoon butter in a skillet over medium heat. Add diced onion and cook 4-5 minutes until translucent, stir in garlic for 30 seconds until fragrant, then remove from heat.
4. Make cream sauce by combining softened cream cheese, sour cream, mayonnaise, milk, beaten eggs if using, ¾ cup cheddar, ¼ cup Parmesan, sautéed onion and garlic, garlic powder, onion powder, paprika, parsley, salt, and pepper in a large bowl. Mix until smooth and creamy.
5. Combine pasta and sauce by adding cooked spaghetti to the cream mixture. Gently toss with tongs until every strand is evenly coated—take care not to break noodles.
6. Transfer to baking dish by pouring coated spaghetti into prepared pan. Spread evenly with a spatula and press down lightly to compact slightly.
7. Prepare topping by mixing breadcrumbs or crushed crackers with remaining cheddar, Parmesan, melted butter, and a pinch of paprika. Sprinkle evenly over casserole.
8. Bake uncovered for 30-35 minutes until top is golden brown and edges are bubbling. If browning too quickly, cover loosely with foil.
9. Rest before serving for 10-15 minutes so casserole sets slightly and scoops cleanly without falling apart.
Essential equipment
9×13 inch baking dish
A standard casserole dish holds the perfect amount for 8 servings. Glass or ceramic distributes heat evenly so everything cooks through uniformly.
Large mixing bowl (4-6 quart)
Tossing pasta with sauce requires plenty of room to work. A roomy bowl prevents spills and makes coating every strand much easier.
Hand mixer or sturdy spoon
Blending cream cheese smoothly requires some power. A hand mixer eliminates lumps while a sturdy wooden spoon works with enough elbow grease.
Colander for draining pasta (PREMIUM)
A quality colander with small holes drains pasta thoroughly without losing noodles. Good drainage prevents watery casserole from excess moisture.

Pro tips and tricks
Want perfectly creamy casserole every single time?
Use room temperature cream cheese because cold cheese won’t blend smoothly and leaves lumps—let it sit out 30 minutes before mixing.
Drain pasta thoroughly since excess water dilutes sauce and creates watery casserole instead of creamy consistency.
Cook spaghetti to al dente because pasta continues softening in the oven—undercooked slightly prevents mushiness.
Let casserole rest after baking so it sets properly and scoops cleanly without falling apart on plates.
Make ahead for better flavor by assembling up to 24 hours early—flavors develop more overnight in the fridge.
Add milk when reheating because a splash restores creaminess that cooking dries out over time.
