How to Make Baked Spaghetti Casserole
Ready to make this delicious dish? Just follow these easy steps. Your family is going to love it!
Step 1: Cook the Spaghetti
Boil the pasta in your big pot with 4 quarts of salted water. Cook for 9-10 minutes until it’s just tender. Then drain it well.
Step 2: Brown the Meat
Cook the ground beef in your skillet on medium-high heat for 8-10 minutes. Break it up with a spoon as it cooks until it’s all brown.
Step 3: Add the Sauce
Stir in the marinara sauce with your cooked beef. Turn the heat down to low. Let it bubble gently for 5 minutes so the flavors mix together.
Step 4: Prepare Cheese Mixture
Mix cream cheese and sour cream in a bowl. Use 8 ounces of cream cheese and 1 cup of sour cream. Stir until it’s nice and smooth.
Step 5: Layer the Casserole
Spread half the spaghetti in your greased baking dish. Then spread that creamy cheese mixture on top. Make sure it covers everything evenly.
Step 6: Add Meat Sauce
Pour the meat sauce over the creamy layer. Spread it out nice and even. Then add the rest of your spaghetti on top of that.
Step 7: Top with Cheese
Sprinkle mozzarella and Parmesan all over the top. Use 2 cups mozzarella and 1/2 cup Parmesan. Cover every bit so it gets golden and bubbly!
Step 8: Bake the Casserole
Bake at 350°F for 30-35 minutes. The cheese should be melted and bubbly. You’ll see it turn golden brown on top. It smells amazing! Let the casserole rest for 10 minutes after you take it out. This helps everything set up nice. Then you can cut perfect pieces to serve.

Tips for the Best Baked Spaghetti Casserole
Want your casserole to turn out perfect every time? Here are my best tips!
- Don’t overcook pasta: Keep it a little firm because it cooks more in the oven.
- Drain meat well: Get rid of extra grease so your casserole isn’t oily.
- Room temperature dairy: Take the cream cheese and sour cream out early so they mix more easily.
- Cover if browning fast: Put foil on top if the cheese gets too brown before it’s done.
- Let it rest: Wait a bit before cutting so the layers stay nice and neat.

Variations and Substitutions
Want to mix things up? Try these fun swaps and changes!
- Ground turkey or chicken: Use these instead of beef if you want something lighter and healthier.
- Italian sausage: This adds more flavor and spice than regular ground beef. So tasty!
- Vegetarian version: Skip the meat and use mushrooms, peppers, and zucchini instead. Still super yummy!
- Different cheese blends: Try cheddar or provolone for a different cheesy flavor that you might like better.
