My house smells amazing these days thanks to this spin on traditional pasta. I've tweaked this velvety Spaghetti Alfredo bake until it's just right, and now my family begs for it weekly. When rich alfredo sauce meets gooey cheese and flavorful meat sauce, each forkful turns into something magical. You'll definitely want this as your regular pasta option.
Why This Dish Stands Out
I'd made basic baked spaghetti for years until I tried mixing in alfredo sauce and wow, what a difference! The silky sauce clinging to every pasta strand combined with that hearty meat sauce just hits different. At our latest block gathering, my neighbor actually tracked me down for the recipe after her children couldn't stop talking about it.
Shopping List
- Spaghetti: 1 lb, boiled until just firm for best noodle consistency.
- Italian Sausage or Ground Beef: 1 lb, browned and broken up for tasty meat layer.
- Marinara Sauce: 1 jar (24 oz), pick one you love for deep tomato flavor.
- Butter: ½ cup, unsalted, creates silky alfredo base.
- Garlic: 2 cloves, finely chopped, adds wonderful scent.
- Heavy Cream: 2 cups, makes everything smooth and rich.
- Parmesan Cheese: 1 cup, freshly grated, brings depth to the alfredo mix.
- Mozzarella Cheese: 2 cups, shredded, creates that wonderful melty top.
- Salt and Pepper: To taste, brings everything together.

The Cooking Process
- Handle the Pasta
- Cook spaghetti in water with salt until firm but not crunchy. Save ¼ cup of the cooking water, then drain the rest and put aside.
- Whip Up the Alfredo
- In a pan, melt your butter over medium heat. Toss in garlic and let it cook about 30 seconds. Pour in heavy cream and cook until it thickens up. Take it off the heat, add salt and pepper, then stir in parmesan until smooth. Use that saved pasta water to thin it if needed.
- Create the Meat Sauce
- Brown your Italian sausage or beef in a skillet until done. Pour off extra fat, then mix in marinara sauce. Let it bubble for 5 minutes.
- Build Your Dish
- Mix cooked pasta with alfredo sauce and spread it in a 9×13-inch baking dish. Layer meat sauce on top, then cover with mozzarella cheese.
- Into the Oven
- Cook in a 375°F (190°C) preheated oven for 20-25 minutes until cheese gets bubbly and golden. Top with fresh basil or parsley before you serve it.
Insider Tricks
Over time I've found a few things that make this dish even better. Don't skimp on the parmesan as it really changes the sauce flavor. My husband goes crazy when I swap in spicy Italian sausage. And that trick with the pasta water really works wonders for getting the sauce just right.
Make It Early
This dish saves me on hectic days. I often get it ready the evening before and stick it in the fridge. Just know you'll need to bake it longer if it's coming straight from cold. You can even freeze it up to 3 months and just let it thaw overnight when you want to use it.

For Big Gatherings
Whenever my sisters bring their kids over, I turn to this dish. It feeds 8 to 10 folks easily and nobody ever turns down seconds. I usually throw together a simple salad and some buttery garlic bread on the side and dinner's done.
Tasty Variations
Sometimes I toss in cooked mushrooms or wilted spinach for something different. My daughter likes it better with turkey sausage while my son always adds extra red pepper flakes to his serving. That's what makes this dish so great you can really switch things up.
Storing Extras
This pasta stays good in the fridge for about 4 days. Make sure to cover it properly when heating it up so all that creaminess doesn't dry out. The microwave does the job for quick meals but for the whole dish I put it back in the oven under foil.

Tasty Companions
We always have this with a fresh Caesar salad and warm garlic bread. For grown-up dinners, I'll grab a bottle of red wine too. Even my kids who normally push food around their plates clean up every bite when this is served.
Week-Ready Meals
This makes Sunday food prep so much easier. I split it into containers for grab-and-go lunches throughout the week. My husband tells me his workmates always look enviously at his lunch when he brings this in.
Wallet-Friendly Goodness
Don't be fooled by how fancy it sounds this dish is really easy on your wallet. I buy pasta when it's marked down and often use cheaper store brand cheeses. It tastes just as wonderful and keeps our food budget in check.

Impressive Dinner Party Dish
Guests always want this recipe when I make it for dinner parties. Something about those creamy layers and that golden cheese topping just looks fancy. Plus I can get it ready beforehand which means I can actually chat with my visitors.
Kid-Approved Choice
My children literally jump for joy when they smell this cooking. It's become our end-of-week tradition and even my picky eaters who normally avoid anything new gobble this up. They can't resist that stretchy cheese pull when it's served.

Gathering Favorite
I've earned quite a name for myself bringing this casserole to community get-togethers. The dish never comes home with leftovers and I've started carrying recipe cards with me. Combining two beloved pasta dishes into one just seems to make everyone smile.
