Welcome to My Kitchen!
If there is one thing that brings everyone running to the dinner table, it is the smell of bubbling cheese and rich garlic cream sauce wafting from the oven. Today, I am sharing a favorite that is guaranteed to become a staple in your meal rotation: my Ultimate Baked Spaghetti Alfredo. It takes the classic, velvety comfort of a traditional alfredo and elevates it by baking it under a golden, irresistible blanket of melted cheese.

Why You Will Love This Comforting Classic
Life gets busy, but sitting down to a hearty, home-cooked meal in your own kitchen should never be complicated. This recipe is the perfect solution for those evenings when you just want something warm and deeply satisfying. Unlike standard stovetop pasta that can sometimes dry out or cool down too quickly, baking this dish locks in all the incredible moisture and flavor.
The heavy cream, butter, and parmesan meld together into a luscious sauce that perfectly coats every single strand of spaghetti. Then, the oven does its magic, turning the cheese topping into a slightly crispy, gooey masterpiece that stretches beautifully when you dig in. It is pure, unadulterated comfort food!

The Secret to the Perfect Cheese Pull
Let’s talk about the absolute best part of this dish—that magnificent baked cheese crust. While the creamy alfredo sauce inside is rich and deeply flavorful, the topping is where the real visual magic happens. For the ultimate stretch, I always recommend using a generous layer of freshly shredded mozzarella.
Pre-shredded cheeses in bags often contain anti-caking agents that prevent them from melting smoothly. Taking a few extra minutes to grate a fresh block of cheese right on your countertop makes all the difference in the world. When your fork breaks through that top layer, you want that dramatic, mouth-watering cheese pull to be absolutely perfect!

What to Serve With Your Baked Pasta
Because this baked spaghetti alfredo is such a rich and decadent main course, I love to keep the side dishes bright and simple. A crisp green salad tossed with a light lemon vinaigrette cuts through the richness beautifully and adds a fresh crunch to the meal.
And of course, you absolutely cannot forget a thick slice of toasted garlic bread to mop up any extra creamy sauce left on your plate!

Ingredients
Method
- Preheat and Prep: Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
- Boil Pasta: Cook the spaghetti in a large pot of salted boiling water according to package instructions until al dente. Drain well and set aside.
- Make the Sauce: In a large, deep skillet or Dutch oven, melt the butter over medium heat. Whisk in the heavy cream and cream cheese until smooth and simmering.
- Add Flavor: Stir in 1 cup of the grated Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper. Continue whisking gently until the sauce thickens slightly and the cheese is fully melted.
- Combine: Add the drained spaghetti directly into the skillet with the alfredo sauce. Toss thoroughly until every strand of pasta is generously coated in the cream sauce.
- Assemble to Bake: Transfer the creamy spaghetti mixture into your prepared baking dish, spreading it out into an even layer.
- Top with Cheese: Sprinkle the remaining 1/2 cup of Parmesan cheese and the 2 cups of shredded mozzarella evenly over the top of the pasta.
- Bake: Bake uncovered for 20-25 minutes, or until the edges are bubbly and the mozzarella cheese is melted and starting to turn golden brown. For an extra crispy crust, broil on high for the last 2 minutes (watch closely so it doesn't burn!).
- Garnish and Serve: Remove from the oven and let it rest for 5 minutes. Garnish with freshly chopped parsley before serving with a side of garlic bread.
