Baked Spaghetti Alfredo with Meat Sauce
This baked spaghetti Alfredo is indulgent and straightforward to prepare. Pasta is tossed in a velvety Alfredo, spread into a baking dish, topped with a savory meat sauce and mozzarella, then baked until golden and bubbly. It’s a crowd-pleaser popular on TikTok for good reason—simple ingredients combine into an impressive, comforting meal.
How to Make TikTok Spaghetti Alfredo
This recipe uses a few basic steps and common pantry items. Bring a large pot of salted water to a boil and cook 16 ounces of spaghetti according to package directions until al dente. Reserve at least 1/4 cup of the starchy pasta water before draining.
For the Alfredo sauce, melt one stick of butter in a skillet over medium heat. Add three crushed garlic cloves and cook briefly until fragrant. Whisk in two cups of heavy cream and simmer, stirring frequently, until the sauce thickens slightly. Remove from heat, season with salt and pepper, and stir in one cup grated Parmesan until melted. If the sauce is too thick, loosen it with a splash of reserved pasta water.
Toss the drained spaghetti with the Alfredo sauce, then spread the coated noodles evenly in a prepared 9×13-inch baking dish.
In a separate skillet, brown one pound of Italian sausage (casings removed) or ground beef over medium heat, breaking it up and cooking until no pink remains. Drain excess grease, then stir in a 24-ounce jar of your favorite marinara or spaghetti sauce. Spread this meat sauce over the Alfredo-coated pasta and finish with about one cup shredded mozzarella.
Bake in a 350°F oven for 25–30 minutes, until the casserole is bubbly and the cheese has melted. Garnish with fresh basil or parsley before serving.
