Chef Emma here, and I’m about to share the casserole that turned me into the potluck queen at every gathering I attend!
The first time I made this creamy baked spaghetti casserole, I was scrambling for something to bring to a neighborhood party. I needed something that would feed a crowd, transport easily, and actually taste good. What I created that night—layers of tender spaghetti, rich meat sauce, and a secretly indulgent cream cheese mixture—disappeared so fast that three people asked for the recipe before I even got a second helping.
This baked spaghetti has become my go-to for everything: potlucks, family dinners, meal prep, new baby deliveries, and those nights when I need comfort food that feels like a warm hug. The cream cheese layer is what makes this different from regular baked spaghetti—it adds this luxurious, tangy creaminess that takes it from “that’s good” to “oh WOW, what IS this?”
What makes this recipe so brilliant is how it delivers maximum impact with familiar, affordable ingredients. No fancy cheeses or hard-to-find items—just ground beef, spaghetti, cream cheese, and marinara. Yet somehow, it tastes like something from an Italian restaurant. The layers create visual drama when you cut into it, the cheese gets bubbly and golden on top, and the whole thing reheats beautifully for days of delicious leftovers.
I’ve made this casserole probably fifty times, tweaking and perfecting until I found the ideal ratio of pasta to sauce to cream cheese, the perfect baking time for bubbly-but-not-dry results, and the best make-ahead strategy. This version consistently earns rave reviews and empty pans at every single gathering.

Directions For Creamy Baked Spaghetti Casserole
Step 1: Cook Pasta
Bring a large pot of salted water to boil. Cook spaghetti according to package directions until al dente (usually 8-10 minutes).
Drain well, toss with olive oil to prevent sticking, and set aside. Don’t overcook—it will cook more in the oven!
Step 2: Make Meat Sauce
While pasta cooks, heat a large skillet over medium-high heat. Add ground beef and diced onion. Cook until beef is browned and onion is softened, about 7-8 minutes, breaking up meat as it cooks.
Drain excess fat if needed (leave a little for flavor).
Step 3: Add Sauce Ingredients
Add minced garlic to browned beef and cook 30 seconds until fragrant.
Add marinara sauce, diced tomatoes (with juices), Italian seasoning, salt, pepper, and sugar if using. Stir to combine.
Step 4: Simmer Sauce
Reduce heat to low and let sauce simmer for 10-15 minutes while you prepare other components.
This allows flavors to meld beautifully. Taste and adjust seasonings!
Step 5: Make Cream Cheese Layer
In a medium bowl, beat together softened cream cheese, sour cream, and cottage cheese until smooth and creamy.
Add minced garlic, salt, and pepper. Mix until well combined. Taste—it should be rich, tangy, and delicious!
Step 6: Preheat Oven
Preheat your oven to 350°F.
Grease a 9×13 inch baking dish with cooking spray or butter.
Step 7: Assemble First Layer
Spread half of the cooked spaghetti evenly in the bottom of the prepared baking dish.
Create an even layer—this is your foundation!
Step 8: Add Cream Cheese Layer
Dollop half of the cream cheese mixture over the spaghetti layer. Use a spatula to spread it as evenly as possible.
Don’t worry if it’s not perfect—it will melt and spread as it bakes!
Step 9: Add Meat Sauce Layer
Spoon half of the meat sauce evenly over the cream cheese layer.
Spread gently to cover.
Step 10: Repeat Layers
Repeat the layers: remaining spaghetti, remaining cream cheese mixture, remaining meat sauce.
Layering creates that beautiful cross-section when you serve!
Step 11: Top with Cheese
Sprinkle mozzarella, cheddar, and Parmesan cheese evenly over the top.
Be generous—this creates that irresistible golden, bubbly top!
Step 12: Bake Covered
Cover the baking dish tightly with aluminum foil. Bake for 30 minutes covered.
This ensures everything heats through without drying out the top cheese.
Step 13: Bake Uncovered
Remove foil and bake uncovered for an additional 15-20 minutes until cheese is melted, golden, and bubbly.
Watch for those golden brown spots—that’s perfection!
Step 14: Rest Before Serving
Remove from oven and let rest for 10-15 minutes before serving.
This crucial step allows everything to set up so slices hold together instead of sliding apart!
Step 15: Serve and Enjoy
Cut into squares, garnish with fresh parsley or basil if desired, and serve hot.
Watch it disappear!
Tips for Perfect Baked Spaghetti
Chef Emma’s Pro Tips
- Soften cream cheese first: Room temperature cream cheese mixes smoothly without lumps. Microwave for 15-20 seconds if needed!
- Don’t overcook pasta: Cook to al dente since it will continue cooking in the oven. Mushy pasta makes mushy casserole.
- Let it rest: Those 10-15 minutes after baking are crucial for slices that hold together beautifully.
- Drain beef well: Excess grease makes the casserole oily. Drain but leave a tablespoon for flavor.
- Cover while baking: Prevents the top from drying out before the inside is hot.
- Make it ahead: Assemble completely, cover, and refrigerate up to 24 hours. Add 10-15 minutes to baking time.
Common Mistakes to Avoid
Using cold cream cheese: Lumpy mixture that won’t spread smoothly. Always soften first!
Overcooking pasta initially: It gets mushy in the oven. Aim for al dente.
Skipping the rest time: Cutting immediately makes everything slide apart. Be patient!
Not draining pasta well: Extra water makes the casserole watery instead of creamy.
Forgetting to cover: Cheese burns before inside is heated. Cover for first 30 minutes!
Delicious Variations For Creamy Baked Spaghetti Casserole
Italian Sausage Version
Use Italian sausage instead of ground beef, or use half beef and half sausage. Remove casings before cooking. Extra flavorful!
Vegetarian Baked Spaghetti

Three-Cheese Luxury
Add ricotta cheese to the cream cheese layer for extra richness. Mix ½ cup ricotta into the cream cheese mixture.
Meat Lover’s Version
Use combination of ground beef, Italian sausage, and crumbled bacon. Ultimate indulgence!
Spinach & Mushroom Addition
Add 2 cups fresh spinach (wilted) and 8 oz sliced mushrooms (sautéed) between layers. Adds nutrition and flavor!

Use shredded chicken instead of beef, buffalo sauce instead of marinara, ranch seasoning in cream cheese layer. Game day heaven!

FAQ For Creamy Baked Spaghetti Casserole
Can I use a different pasta shape?
Yes! Penne, rigatoni, ziti, or even rotini work great. Just cook according to package directions and assemble the same way.
Do I have to use cottage cheese?
You can substitute with ricotta cheese for smoother texture, or use all cream cheese and sour cream (increase each by ½ cup).
Can I make this gluten-free?
Absolutely! Use gluten-free pasta and ensure your marinara sauce is gluten-free. Everything else naturally is!
Why is my casserole watery?
Make sure to drain pasta very well. Also, don’t skip the resting time—it needs those 10-15 minutes to set up and absorb excess liquid.
Can I use ground turkey instead?
Yes! Ground turkey, chicken, or Italian sausage all work beautifully. Just cook the same way.
How do I know when it’s done?
Cheese should be melted, golden, and bubbly around edges. Internal temperature should reach 165°F. Sauce should be bubbling at edges.
Can I add vegetables?
Absolutely! Sautéed mushrooms, bell peppers, zucchini, or spinach are all delicious additions. Add to meat sauce or layer separately.
What if I don’t have a 9×13 pan?
Use two 8×8 pans, a deep 9×9 pan (increase baking time), or a large deep casserole dish. Just adjust cooking time based on depth.
