How to Make The Ultimate Baked Spaghetti Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350ºF and lightly spraying a 9×13-inch baking dish with cooking spray. This simple step ensures your baked spaghetti won’t stick and will come out perfectly in one piece.
Step 2: Cook and Toss the Spaghetti
Boil the spaghetti until just tender according to package directions, then drain well. Next, whisk together the eggs, parmesan cheese, and melted butter, then toss everything with the warm pasta. This mixture helps the noodles stay moist and flavorful as they bake.
Step 3: Layer the Creamy Mixture
In a small bowl, blend the Italian seasoning, minced garlic, softened cream cheese, and sour cream until smooth. Spread this luscious cream cheese mixture evenly over the pasta in your baking dish—it’s what brings the recipe’s signature creamy texture.
Step 4: Add Meat and Sauce Layers
Combine your cooked Italian sausage or hamburger with the jar of spaghetti sauce, stirring to mix all that rich flavor. Spread this meaty sauce blend over the cream cheese layer, making sure every bit is covered for maximum taste in every bite.
Step 5: Top with Cheese and Bake
Sprinkle the shredded mozzarella evenly over the top—this cheese will melt into a bubbly, golden crown for your baked spaghetti. Bake in the preheated oven for 45 minutes, or until the cheese is deliciously melted and bubbling around the edges.
How to Serve The Ultimate Baked Spaghetti Recipe

Garnishes
Freshly chopped basil or parsley sprinkled over the top just before serving adds a bright, herbal contrast that instantly lifts the dish. A light dusting of extra parmesan can also add a final touch of cheesy goodness and elevate the presentation.
Side Dishes
Serve this bountiful baked spaghetti alongside a crisp green salad or garlic bread for a well-rounded meal. Roasted vegetables or a simple Caesar salad also make excellent, fresh sides that balance the richness of the pasta.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftover baked spaghetti keeps well in an airtight container in the refrigerator for up to 3 days. Make sure to let it cool to room temperature before storing to preserve the creamy texture without sogginess.
Freezing
The Ultimate Baked Spaghetti Recipe freezes beautifully! Wrap it tightly in foil or place it in a freezer-safe container and freeze for up to 3 months. This makes it ideal for batch cooking or easy weeknight dinners.

FAQs
Can I use a different type of pasta for this recipe?
Absolutely! While thin spaghetti is recommended to keep the texture light and silky, you can swap in penne, rigatoni, or any pasta you prefer. Just adjust the cooking time accordingly to ensure it’s al dente before baking.
What can I substitute for Italian sausage?
If you prefer a milder flavor or need a vegetarian option, ground beef or turkey are great alternatives. For a veggie version, try sautéed mushrooms or a plant-based meat substitute to keep all the deliciousness intact.
Is it possible to make The Ultimate Baked Spaghetti Recipe gluten-free?
Yes! Just use your favorite gluten-free pasta and double-check that the spaghetti sauce and other ingredients don’t contain gluten. Cooking and baking times remain the same, making it an easy swap.
Can I prepare this recipe in advance?
Definitely. You can assemble the dish and refrigerate it overnight before baking. This makes it perfect for busy days or hosting, as the flavors meld wonderfully with some resting time.
How do I know when the baked spaghetti is done?
The cheese on top should be fully melted and bubbly, with a slight golden brown color at the edges. The internal temperature should be hot and steaming, usually about 45 minutes in the oven at 350ºF.
