Alfredo Spaghetti

Pro tips

• Brown meat thoroughly and drain excess fat before mixing into the pasta to prevent a greasy casserole.
• Use freshly grated cheese over pre-shredded for better melting and creamier texture.
• Don't overcook the spaghetti before baking—it will soften further in the oven; aim for al dente.
• Cover the casserole with foil for the first half of baking to prevent the top from browning too quickly while the inside heats through.

Substitutions

• Ground beef → Italian sausage or ground turkey (adjust seasoning to taste)
• Heavy cream → half-and-half or whole milk with a cornstarch slurry (sauce will be slightly thinner)
• Parmesan → Pecorino Romano (sharper, saltier flavor)

Storage & make-ahead

Store covered in the refrigerator up to 4 days. Reheat in a 350°F oven covered with foil, or microwave with a splash of milk to restore creaminess.

Can I make this alfredo spaghetti casserole ahead of time?

Yes, assemble the casserole in the baking dish, cover, and refrigerate up to 24 hours before baking. Add 5-10 minutes to the bake time if baking from cold.

What type of meat works best in alfredo spaghetti?

Ground beef or Italian sausage are traditional choices. Brown and drain the meat fully before mixing into the pasta to avoid excess grease.

How do I keep the alfredo sauce creamy in the oven?

Don't overbake the casserole. Bake just until the top is golden and cheese melts; excess heat can cause the sauce to separate or become grainy.

Can I freeze leftover alfredo spaghetti casserole?

Yes, cool completely, then cover and freeze up to 3 months. Thaw overnight in the refrigerator and reheat at 350°F covered for 20-30 minutes until warmed through.

What's the best way to reheat this dish?
