Ingredients for baked spaghetti recipe with cream cheese and sour cream
Pantry staples that transform into creamy, cheesy baked spaghetti perfection in one dish!
| Ingredient | Amount | Notes |
|---|---|---|
| Spaghetti 🍝 | 12 oz | Uncooked, al dente preferred |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat for richness |
| Cream Cheese 🧀 | 8 oz | Room temperature, full-fat |
| Sour Cream 🥛 | ½ cup | Full-fat for tangy depth |
| Shredded Mozzarella Cheese 🧀 | 2 cups | Part-skim or whole milk |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, preferred |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening sauce |
| Milk 🥛 | ¼ cup | Whole milk preferred |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Dried Parsley 🌿 | 1 tbsp | Chopped, for garnish |
| Red Pepper Flakes 🌶️ | ½ tsp | Optional, for heat |
The cream cheese is where all the magic happens—full-fat, room-temperature is non-negotiable. Grab the Philadelphia brand from the dairy aisle, not the spreadable kind. For the mozzarella, pre-shredded gets clumpy—buy a block and shred it yourself. The Parmesan? Freshly grated makes a world of difference, but the pre-grated stuff in a jar works in a pinch. I always double-check the flour is all-purpose (not cake flour) and grab the Gold Medal brand—it's my go-to for reliable baking. The butter needs to be melted, but not hot—just warm enough to coat your fingers.
No cream cheese? Ricotta or mascarpone in a 1:1 swap works beautifully. Short on sour cream? Greek yogurt at half the amount gives you that tangy kick. The mozzarella block? Low-moisture is best, but if you grab the wrong kind, just pat it dry with a paper towel before shredding. For the garlic, fresh is ideal, but if you're in a rush, jarred minced garlic (the kind in tubes) works—just use half the amount. The milk can be any kind, but whole milk gives the sauce the most luxurious texture. And if you're feeling adventurous, swap the parsley for fresh basil—it changes the whole vibe!
This dish reheats like a dream—better the next day when all those flavors meld together. Store leftovers covered in the fridge for 3-4 days, or freeze portions for up to 2 months. I always make a double batch because it's impossible to resist seconds. The broiled topping stays crispy for about 20 minutes after baking, so serve it right away if you're sharing. For extra crispiness, broil for just 2-3 minutes—don't walk away, or it'll burn faster than you think!

Step-by-step instructions for creamy baked spaghetti
This one-dish wonder delivers ultimate comfort with creamy layers and melty cheese—let's bake it right!
🍳 Step 1: Cook the Spaghetti Al Dente
Boil 12 oz spaghetti in heavily salted water (like the sea) until 1 minute before package directions for al dente. Reserve 1 cup pasta water before draining—this starchy liquid is our secret weapon for creamy perfection. Drain and return the pasta to the pot.
Here's the thing—undercooking slightly ensures the pasta finishes cooking in the oven while soaking up all that rich sauce. If you overcook it now, you'll end up with mushy noodles later. Toss the drained pasta with 1 tbsp melted butter to prevent sticking during assembly.
👨🍳 Step 2: Make the Creamy Cheese Sauce
In a large bowl, combine the 8 oz room-temperature cream cheese, 0.5 cup sour cream, 0.5 cup melted butter, 0.25 cup milk, 1 tbsp flour, 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp red pepper flakes (if using). Mix until completely smooth—no lumps allowed!
I like to use a hand mixer here for about 30 seconds to ensure everything's perfectly emulsified. The sauce should be thick but still pourable. If it looks too stiff, whisk in 1-2 tablespoons of the reserved pasta water. This is where that starchy water shines—it helps create that signature creamy texture.
🥘 Step 3: Combine Pasta and Sauce
Pour the creamy mixture over the warm spaghetti in the pot and toss vigorously with tongs for 2-3 minutes until every strand is fully coated. You want each noodle to be completely enrobed in that rich, velvety sauce—this is where the magic happens!
Here's a pro tip: If the sauce seems too thick at this point, don't panic. Just add 2-3 tablespoons of that reserved pasta water and toss again. The sauce will come together beautifully in the oven. The goal is a consistency that clings to the pasta without being watery.
🔥 Step 4: Assemble and Bake to Bubbly Perfection
Transfer the pasta mixture to a 9x13-inch baking dish (greased or lined with parchment paper). Spread it out evenly, then sprinkle the top with 2 cups shredded mozzarella and 0.25 cup grated parmesan. For extra flavor, scatter the 3 minced garlic cloves and 1 tbsp dried parsley over the top.
Bake at 375°F for 25-30 minutes until the cheese is golden brown and bubbling vigorously at the edges. The center should still be slightly jiggly—this indicates it's perfectly creamy inside. If you're worried about browning too quickly, tent the dish with foil for the last 10 minutes if needed.
⏰ Step 5: Rest and Serve Warm
Remove from the oven and let it rest for 5-10 minutes before serving. This resting time allows the layers to set slightly, making it easier to slice and serve. The dish will be hot but more manageable to handle.
Serve immediately with extra grated parmesan and fresh parsley if desired. Each forkful should deliver that perfect balance of creamy sauce, al dente pasta, and melty cheese. This dish tastes even better the next day, so make extra if you can—it's that good!
Pro Tips For Making Baked Spaghetti Recipe With Cream Cheese And Sour Cream
- Cook Pasta Al Dente: Undercooked spaghetti turns mushy when baked—overcooked turns to glue. Boil it one minute less than package instructions, then drain and toss immediately with butter while hot. The slight firmness holds up better when mixed with cream cheese later.
- Melt Cheese Slowly: Dump cold cream cheese and sour cream straight into a hot casserole, and you’ll end up with lumps. Warm them together in a bowl first—just until smooth, about 30 seconds in the microwave—so they blend seamlessly into the pasta.
- Skip the Overmixing: I used to fold everything like I was making lasagna, but this dish works better when it’s rough. Toss the pasta with butter, then just roughly distribute the cheese mixture—uneven pockets of cream cheese make it richer, not ruined.
- Bake at 375°F: Too high, and the top burns before the center sets. Too low, and the cheese never melts properly. Stick to 375°F—it’s the sweet spot where the mozzarella browns just enough to taste crispy without turning to rubber. Cover with foil the first 20 minutes if you’re worried.
Storing and reheating your baked spaghetti recipe with cream cheese and sour cream
Fridge Storage Tips
Let your baked spaghetti cool completely before storing—about 2 hours at room temperature. Transfer to an airtight container with a tight-fitting lid (I use Rubbermaid Brilliance containers) and refrigerate for up to 4 days. The flavors actually deepen overnight, making leftovers even more delicious. 💛
Freezer-Friendly Prep
For long-term storage, freeze portions in single-serving portions using quart-sized freezer bags or glass containers. Leave 1-inch headspace since the sauce expands slightly when frozen. Label with the date—this dish keeps for 2-3 months without texture loss. Thaw overnight in the fridge before reheating.
Stovetop Reheating
My favorite method is stovetop reheating for that restaurant-quality texture. Cover the baked spaghetti with a splash of milk or water (about 2-3 tablespoons) to prevent drying.
Heat on low-medium for 10-12 minutes, stirring occasionally, until bubbly and heated through. The extra liquid keeps the sauce creamy, not dry. ✨
Oven Refresh Method
For a crispy top, transfer leftovers to a baking dish, cover with foil, and warm at 350°F for 15 minutes. Remove foil for the last 2-3 minutes to restore that golden-brown crust.
This works especially well if you're serving a crowd—just pop it back in the oven while you set the table.
Microwave Shortcut
When you're in a hurry, microwave individual portions covered with a damp paper towel for 90 seconds on 50% power. Stir halfway through to redistribute the sauce. Add a splash of milk if it looks dry—this keeps the texture luscious. Perfect for quick lunches or late-night cravings! 💡
Broiler Crisp Finish
For that showstopping restaurant finish, broil for 1-2 minutes** on high after reheating. Watch closely—cheese browns fast! This adds a crispy top layer that makes even reheated portions feel special. Just be prepared to work quickly before it burns. 🔥
Nutrition facts
Frequently asked questions
Can I use other pasta shapes instead of spaghetti?
This recipe works beautifully with penne, rigatoni, or even fettuccine. The creamy sauce will cling differently to shorter shapes like penne, while long noodles like fettuccine create elegant layers. For best results, choose pasta with ridges or grooves to help the sauce cling better.
Why did my baked spaghetti turn out too dry?
Dry baked spaghetti usually means the sauce was too thick or the pasta cooked too long. Always reserve 1 cup pasta water to adjust consistency, and cook pasta just 1 minute less than package directions. If reheating leftovers, add 1-2 tablespoons milk or water before warming to restore creaminess.
Can I make this dish ahead of time?
This recipe actually tastes better the next day! Assemble completely and refrigerate unbaked for up to 24 hours. When ready to bake, add 5-10 minutes to the baking time (cover with foil if needed). The flavors meld beautifully overnight, making it perfect for meal prep.
What can I add for extra protein?
Try mixing in 1 cup cooked ground beef, 1 cup diced chicken, or 1 cup crumbled bacon when combining the sauce and pasta. For vegetarian options, stir in 1 cup sautéed mushrooms or 1 cup spinach during the final toss. Just be sure not to overfill the baking dish—this keeps the texture creamy.
How do I get that perfect golden-brown crust?
The secret is broiling for just 2-3 minutes at the end! After regular baking, switch to broil mode and watch closely—cheese browns fast. For extra insurance, sprinkle 1 tbsp breadcrumbs on top before broiling. This creates that coveted crispy top while keeping the inside creamy. Just don't walk away—it burns faster than you think!
