Ingredients for baked spaghetti with mozzarella cheese
Restaurant-quality casserole starts with these 12 essential ingredients—each playing a crucial role in texture and flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Spaghetti 🍝 | 1 ½ lb | Dry, medium thickness preferred |
| Marinara Sauce 🍅 | 2 ½ cups | High-quality, chunky preferred |
| Mozzarella Cheese 🧀 | 24 oz | Fresh, low-moisture block preferred |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated from block |
| Garlic Cloves 🧄 | 4 cloves | Minced for sauce enhancement |
| Olive Oil 🫒 | ¼ cup | Extra-virgin for richness |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Basil 🌿 | ¼ cup | Chopped, for garnish |
| Red Pepper Flakes 🌶️ | ½ tsp | Optional, for heat |
| Heavy Cream 🥛 | ¼ cup | For extra creaminess |
| Butter 🧈 | 2 tbsp | Unsalted, for topping |
The spaghetti is non-negotiable for texture—medium thickness holds up best to baking. De Cecco or Barilla are my go-tos for consistent al dente results. For the cheese, low-moisture mozzarella is key—it melts beautifully without making the dish soggy. Whole Foods Market sells excellent pre-shredded options, but grating your own from a block ensures better texture. The marinara should be chunky (like Rao's or Victoria) to add depth of flavor that jarred sauces often lack. Fresh basil and garlic are worth the extra minute to mince yourself—they elevate the dish from good to exceptional.
No fresh basil? Dried oregano at half the amount works in a pinch, though it won't have the same brightness. Substituting heavy cream with Greek yogurt (same quantity) adds tanginess without altering the texture. For a vegetarian twist, mushroom marinara replaces traditional sauce while keeping the dish rich. If you're avoiding dairy, vegan mozzarella (like Miyoko's) melts surprisingly well, though texture will differ slightly. The red pepper flakes are optional but recommended—start with half the amount and adjust to taste. Pre-shredded cheese? Toss it with cornstarch to prevent excess moisture during baking.
Pre-cooked spaghetti keeps for 2 days in the fridge—reheat gently with a splash of water to maintain tenderness. The assembled casserole reheats beautifully—375°F for 15-20 minutes until bubbly. For meal prep, assemble the dish one day ahead and refrigerate uncovered for 30 minutes before baking to develop deeper flavors. Leftovers freeze well for up to 3 months—portion into individual servings for easy reheating. The cheese topping crisps perfectly when baked, so don't skip the final 5 minutes of broiling if you want that golden finish.

Step-by-step instructions for baked spaghetti with mozzarella cheese
Master this cheesy casserole technique for perfectly al dente noodles and a bubbly, golden crust.
Cook the Spaghetti to Al Dente Perfection
Bring a large pot of water to a rolling boil and add 1.5 lb spaghetti along with 1.5 tsp salt. Cook until 1 minute shy of the package's al dente time—this ensures the noodles finish cooking in the oven. Reserve 1 cup pasta water before draining, as it contains vital starch for binding the sauce.
Drain the spaghetti and immediately transfer it to a large mixing bowl. Toss with 2.5 cups marinara sauce and 2 tbsp butter, breaking up any clumps. The butter adds richness that carries through the baking process. This step prevents a dry casserole by ensuring the noodles are thoroughly coated in sauce.
Prepare the Cheese Mixture for Maximum Creaminess
In a separate bowl, combine 24 oz mozzarella cheese (cut into small cubes), 0.5 cup parmesan cheese, 0.25 cup heavy cream, 0.5 tsp black pepper, and 0.5 tsp red pepper flakes. Mix gently to distribute the cream evenly—this creates pockets of luxurious meltiness throughout the dish. The heavy cream prevents the cheese from becoming overly dry during baking.
Fold this cheese mixture into the spaghetti until fully incorporated. The mozzarella should be evenly distributed, with no large chunks remaining. This is where the magic happens—the combination of melted mozzarella and parmesan creates that signature gooey texture we all love. If the mixture seems too dry, add 2-3 tablespoons of reserved pasta water to help bind everything together.
Assemble and Bake for a Golden Crust
Transfer the spaghetti mixture to a 9x13-inch baking dish, spreading it evenly. Press down lightly to compact the noodles—this prevents them from shifting during baking. Drizzle the top with the remaining 0.25 cup olive oil and sprinkle with 0.25 cup chopped fresh basil. The olive oil promotes browning while adding depth of flavor.
Bake at 375°F for 25-30 minutes until the top is deep golden brown and bubbling vigorously. The edges should be crispy, while the center remains tender. If the top browns too quickly, tent loosely with foil for the last 5-10 minutes of baking to prevent over-browning. The internal temperature should reach 165°F at the thickest part.
Rest and Serve for Perfect Texture
Remove the baking dish from the oven and let it rest for 10 minutes before serving. This crucial step allows the cheese to set slightly and the juices to redistribute, ensuring each forkful is creamy and cohesive. The dish will be extremely hot—handle with oven mitts to avoid burns.
Garnish with additional chopped fresh basil and serve immediately with a side salad or garlic bread. The spaghetti should be al dente with a satisfying bite, while the cheese sauce remains velvety smooth. For extra richness, drizzle with additional olive oil or a sprinkle of freshly grated parmesan right before serving.
Pro Tips For Making Baked Spaghetti With Mozzarella Cheese
- Pre-Cook Spaghetti Al Dente: Tossing raw spaghetti into the sauce and baking it sounds lazy, but it works—just don’t overcook. Boil your noodles one minute less than package instructions (they’ll finish in the oven), then drain and rinse briefly in cold water to stop cooking. This keeps them from turning mushy when the cheese melts.
- Shred Mozzarella Like a Pro: I used to grab pre-shredded mozzarella straight from the bag, but it’s packed with anti-caking agents that make your baked spaghetti watery. Instead, buy a block of fresh mozzarella, slice it into thin strips, then shred it yourself—it melts like a dream and adds that gooey texture we all crave.
- Don’t Skip the Garlic Sauté: Raw garlic cloves in marinara? Nah. Sauté 2-3 minced cloves in olive oil until fragrant and just golden—this builds flavor that baked heat can’t replicate. If you’re short on time, use garlic powder (½ tsp), but the real deal makes a difference when that cheese starts bubbling.
- Cover It Early, Uncover Late: The first 20 minutes of baking? Keep that dish covered with foil to trap steam and help the sauce cling to the noodles. Then, uncover for the last 5-10 minutes—this lets the cheese brown and crisp slightly, giving you that restaurant-style crust on top. (Yes, even if it looks weird halfway through.)
Serving suggestions for this recipe
Classic Side Pairings
A simple arugula salad with lemon vinaigrette cuts through the richness beautifully. Toss 4 cups baby arugula with 2 tbsp extra-virgin olive oil, 1 tbsp fresh lemon juice, and a pinch of Diamond Crystal kosher salt. The peppery bite refreshes your palate after each cheesy bite. 🥗
For a heartier option, serve with garlic bread made from a baguette brushed with 2 tbsp olive oil and topped with 3 minced garlic cloves and 2 tbsp grated parmesan. Toast until golden and crispy—it's perfect for soaking up any extra sauce.
Italian-Inspired Additions
Add a roasted tomato salad to complement the dish. Halve 4 large Roma tomatoes, toss with 1 tbsp olive oil, ½ tsp salt, and ¼ tsp black pepper, then roast at 400°F for 15 minutes.
The sweet, caramelized tomatoes balance the richness of the baked spaghetti.
For a more substantial side, serve with creamy polenta cooked in 2 cups whole milk and 2 cups chicken broth until thick and creamy. Stir in 2 tbsp butter and ½ cup grated parmesan for a comforting contrast to the cheesy pasta.
Dessert Pairings
Finish the meal with a light dessert like panna cotta topped with fresh berries. The creamy texture contrasts perfectly with the savory spaghetti. For a quicker option, serve affogato—vanilla gelato drowned in a shot of hot espresso—it's a refreshing way to end the meal. ☕
Drink Recommendations
A crisp Italian white wine like Pinot Grigio or Vermentino complements the dish beautifully. The acidity cuts through the richness, while the citrus notes enhance the tomato sauce. For a non-alcoholic option, try sparkling water with lemon slices to cleanse your palate between bites.
If you prefer red wine, a light Chianti with its bright acidity and cherry notes pairs well. Avoid heavy, oaky wines that would overpower the delicate flavors of the baked spaghetti. A dry rosé is also a fantastic summer-friendly choice.

Frequently asked questions
Why does my baked spaghetti get soggy in the middle?
The most common cause is overcooking the pasta before baking or not draining it properly. Always cook spaghetti 1 minute less than package instructions and drain thoroughly. Another trick is to press the noodles down firmly in the baking dish—this creates a compact base that holds its shape. If using pre-cooked pasta, toss it with a little reserved pasta water before assembling to help bind the sauce.
Can I use pre-shredded cheese instead of block mozzarella?
Pre-shredded cheese works, but it often contains anti-caking agents that can make your dish dry. If you must use it, mix the cheese with 1 tablespoon cornstarch per 8 oz to absorb excess moisture. For best results, grate your own mozzarella from a block—it melts more smoothly and creates that perfect stretchy texture. The difference is noticeable in the final dish's creaminess.
How do I make the top extra crispy without burning it?
Broil the dish for the last 2-3 minutes at 400°F after regular baking. Watch closely to prevent burning! For even crispier results, sprinkle 1/4 cup breadcrumbs mixed with 1 tablespoon grated parmesan on top before the final broil. This creates a golden, crunchy crust while keeping the inside creamy. Just be sure to broil on low heat to avoid scorching.
Can I make this ahead of time for meal prep?
Assemble the dish one day ahead and refrigerate uncovered for 30 minutes before baking. The cold temperatures help develop deeper flavors. For freezing, bake the dish, let it cool completely, then portion into individual servings. Freeze for up to 3 months and reheat at 375°F for 15-20 minutes until bubbly. The texture holds up surprisingly well when reheated properly.
What's the best way to reheat leftovers?
Reheat in the oven for the best texture—cover with foil and bake at 375°F for 15-20 minutes until warmed through. This prevents the cheese from becoming rubbery. If using the microwave, cover with a damp paper towel and heat in 30-second intervals on medium power, stirring between each interval. Add a splash of water or milk to help restore creaminess if the dish seems dry.
