TikTok Spaghetti Alfredo Recipe – our favorite baked spaghetti casserole! Pasta tossed with a creamy homemade alfredo sauce, topped with a quick meat sauce and mozzarella cheese. This is amazing! Italian sausage, spaghetti sauce, heavy whipping cream, butter, garlic, parmesan cheese, spaghetti, and mozzarella cheese. Serve with a salad and garlic bread for a restaurant-quality meal.
Preheat oven to 350ºF. Spray a 9x13-inch baking dish with nonstick cooking spray. Set aside.
Bring a large pot of water to a boil over medium-high heat. Cook spaghetti noodles according to package instructions for al dente. Reserve at least 1/4 cup of the pasta water. Drain the remaining water and set aside.
To make the homemade alfredo sauce, melt a stick of butter in a large skillet over medium-high heat. Add garlic cloves and cook for 30 seconds. Whisk in heavy cream. Cook, stirring frequently, until the sauce has thickened. Remove the skillet from the heat. Season with salt and black pepper. Add parmesan cheese to the cream mixture and stir until the cheese melts. If the sauce is too thick, add a splash of pasta water to reach the desired consistency.
Toss cooked spaghetti with the alfredo sauce. Use tongs to spread spaghetti into the bottom of the prepared baking dish.
In a large skillet, cook Italian sausage or ground beef over medium heat until browned and no longer pink. Drain excess grease. Stir in a jar of your favorite marinara sauce. Spread meat sauce over the alfredo layer. Top casserole with mozzarella cheese.
Bake for 25 to 30 minutes until bubbly and the cheese has melted. Garnish with fresh basil or parsley.
Notes:
Can substitute ground turkey or turkey sausage for reduced calories.
My favorite store-bought spaghetti sauces are Trader Joe’s Roasted Garlic Marinara (green label), Carbone, Rao’s, and La Famiglia DelGrosso.
I use spaghetti noodles. Can substitute linguine or fettuccine.
Can Spaghetti Alfredo be made in advance? Yes! Assemble the casserole and cover the panwith plastic wrap. Place in the refrigerator until ready to bake.
If baking cold straight from the fridge, you will need to add 15 to 20 minutes to the cooking time.
Can I freeze Baked Spaghetti? Absolutely! Assemble the casserole and cool completely. Cover the dish with plastic wrap and aluminum foil. Store in the freezer for up to 3 months.
When ready to bake, thaw completely and bake as directed below.
This makes a lot of food. You can split the recipe into two 8×8 foil pans – bake one now and freeze one unbaked for later.
Store leftovers in an airtight container in the refrigerator.
