How to Make Baked Spaghetti Casserole Recipe
Step 1: Get Started
Preheat your oven to 350°F and grease a deep 13×9-inch baking dish so your casserole won’t stick. This simple prep ensures a smooth final step when your casserole is ready to come out bubbling and golden. Also, gather all your ingredients for an easy cooking process.
Step 2: Cook the Spaghetti
Boil the spaghetti according to the package instructions until it’s perfectly al dente. Once drained, return it to the pot, drizzle with olive oil, and cover it up to keep warm and prevent the noodles from sticking together. This step sets a tender pasta foundation that soaks up all the delicious sauce later.
Step 3: Brown the Beef and Vegetables
Heat oil in a large skillet over medium-high heat, then add the ground beef seasoned with salt, pepper, and garlic powder. Brown the meat until no longer pink, then drain any excess fat if you like. Toss in diced onion and celery, letting them soften for about 5 to 6 minutes until they’re tender and fragrant. This mix brings a wonderful depth of flavor and texture to your casserole.
Step 4: Make the Tomato Sauce
Reduce the heat to medium and stir in Italian seasoning and tomato paste right into your beef and veggie mixture. Add the can of diced tomatoes and let everything simmer together for 5 minutes so the flavors meld and the sauce thickens slightly. Turning off the heat here locks in all those beautiful, robust flavors.
Step 5: Stir Up the Cheese Layer
In a bowl, combine softened cream cheese, ricotta, and sour cream until you have a smooth, creamy mixture that will add richness and subtle tang. No need to overthink it—just blend until creamy and ready to spread over the pasta for that dreamy, cheesy layer.
Step 6: Put It Together
Start with a quarter of the meat sauce spread evenly on the bottom of your prepared casserole dish. Next, layer half of the spaghetti over the sauce. Spread the creamy cheese mixture on top, then add the remaining spaghetti. Finally, spoon the rest of the meat sauce over the noodles and sprinkle shredded mozzarella evenly over everything. This layering locks in moisture and flavor, resulting in the perfect baked casserole.
Step 7: Bake
Bake uncovered at 350°F for 35 to 45 minutes until the casserole is bubbly and the mozzarella is beautifully melted and slightly golden. Let the casserole sit for a few minutes after removing it from the oven so it firms up and slices neatly. Now you’re ready to serve up a plateful of pure comfort!
How to Serve Baked Spaghetti Casserole Recipe
Garnishes
Sprinkle some freshly chopped parsley or basil over the top to add a pop of bright green color and a burst of fresh herbaceous flavor. A light dusting of grated Parmesan can also take this casserole to the next level, adding a salty, nutty finish that complements the melty mozzarella perfectly.
Side Dishes
This Baked Spaghetti Casserole Recipe pairs beautifully with crisp, refreshing side salads like a Caesar or mixed greens tossed with a simple vinaigrette. Garlic bread or warm dinner rolls are fantastic for mopping up those extra sauce bits, rounding out the meal with delightful crunch and aromatic garlic flavor.
Creative Ways to Present
If you want to make dinner feel extra special, serve the casserole in individual ramekins or small oven-safe bowls. You can also add layers of roasted vegetables like zucchini or bell peppers inside the casserole for added nutrition and color. For a fun twist, sprinkle with red pepper flakes before baking for a subtle kick.
Make Ahead and Storage
Storing Leftovers
After your meal, allow the casserole to cool completely, then cover it tightly with plastic wrap or foil and store it in the refrigerator. It will stay fresh for about 3 to 4 days, making it an excellent option for next-day lunches or quick dinners.
Freezing
You can freeze this Baked Spaghetti Casserole Recipe either before or after baking. Just wrap it well with plastic wrap and foil, or place it in an airtight container. It will keep beautifully for up to 3 months. When ready to enjoy again, thaw overnight in the fridge before reheating.
Reheating
Reheat individual portions in the microwave for a quick meal, or warm the entire casserole in the oven at 350°F until heated through and bubbly again, which usually takes about 20 to 25 minutes. To keep the top from drying out, cover with foil during reheating if desired.
FAQs
Can I use a different type of pasta in this recipe?
Absolutely! While spaghetti is traditional and works beautifully here, you can swap in penne, rigatoni, or even fusilli. Just make sure to adjust the cooking time accordingly to keep everything perfectly al dente.
Is there a vegetarian version of this Baked Spaghetti Casserole Recipe?
Yes! Replace the ground beef with a mix of sautéed mushrooms, zucchini, and bell peppers or use plant-based ground meat alternatives. The cheese and sauce layers keep the casserole rich and satisfying without meat.
Can I prepare this casserole ahead of time and bake it later?
Definitely. Assemble the casserole as directed, then cover and refrigerate it for up to 24 hours before baking. This makes it a perfect make-ahead meal for busy days or entertaining.
What is the best type of mozzarella to use?
Shredded part-skim mozzarella melts well and is less greasy, making it a great choice for topping casseroles. For extra creamy results, whole milk mozzarella can also be used, but it may be a bit richer.
Do I need to cook the spaghetti fully before baking?
Yes, cooking the spaghetti until al dente before assembling ensures it bakes perfectly without becoming mushy. The pasta will absorb the sauce as it bakes, so starting with slightly firm noodles is key.

I can’t recommend this Baked Spaghetti Casserole Recipe enough for anyone looking to bring a big bowl of comfort and joy to the dinner table. Its layers of tender pasta, savory meat sauce, and creamy cheese make it a guaranteed family favorite.
