Ingredients for baked spaghetti with mozzarella cheese
Just 13 essential ingredients transform into a restaurant-worthy pasta bake that's crispy, cheesy, and impossible to resist.
| Ingredient | Amount | Notes |
|---|---|---|
| Spaghetti 🍝 | 12 oz | Dry, medium thickness |
| Marinara Sauce 🍅 | 2 ½ cups | High-quality, homemade or store-bought |
| Part-Skim Mozzarella Cheese 🧀 | 16 oz | Freshly shredded, low-moisture preferred |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, for topping |
| Panko Breadcrumbs 🍞 | ¼ cup | For crispy topping |
| Butter 🧈 | 2 tbsp | Melted, for extra richness |
| Garlic Cloves 🧄 | 3 cloves | Minced, for flavor depth |
| Fresh Basil Leaves 🌿 | ¼ cup | Chopped, for freshness |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin, for drizzling |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Ground Beef (optional) 🥩 | 1 lb | 80/20 fat ratio, browned |
| Italian Seasoning 🌿 | 1 tsp | For extra flavor layer |
The mozzarella makes or breaks this dish—low-moisture, freshly shredded is non-negotiable. Whole Foods or local Italian markets have the best quality, or grab a block and shred it yourself. The Parmesan? Freshly grated from a wedge adds that nutty depth pre-shredded can't match. For the pasta, De Cecco or Barilla are my go-tos—they hold up better to baking. And that crispy topping? Panko plus melted butter is the secret weapon—no sad breadcrumbs here.
No marinara on hand? Crushed tomatoes with garlic, basil, and a pinch of sugar works in a pinch. Skipping the beef? Sautéed mushrooms or roasted bell peppers add meaty texture. The Italian seasoning can be swapped for dried oregano plus red pepper flakes if you're out. Fresh basil? Dried oregano at half the amount gets you close. Pro tip: Toast your breadcrumbs in the butter before sprinkling—they'll be extra crispy.
This bake reheats beautifully—just cover with foil and warm in the oven. Keeps for 3-4 days in the fridge, freezes for 2 months (though it's rarely around that long). I always make a double batch—one for dinner, one for lunches. Store leftovers in airtight containers with a paper towel on top to keep that crispy texture intact.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe when I’m too tired to wash a million dishes. Toss everything—cooked spaghetti, marinara, mozzarella, and panko—into one baking dish, and the oven does all the work. No boiling over saucepans or sticky pots to scrub later.
- Cheesy Crispy Perfection: The panko on top isn’t just for looks—it turns golden and crunchy while the mozzarella melts into gooey, stretchy strands underneath. Honestly, that contrast is what makes it ridiculous good. The parmesan sprinkle at the end? The cherry on top.
- Weeknight to Party Fix: Between us, this is my go-to for both lazy Tuesdays and unexpected guests. Double the batch ahead, and it reheats like a dream—no soggy pasta in sight. Serve it with a simple salad, and suddenly you’ve got a dinner that feels fancy without the fuss.
- Budget-Friendly Leftovers: Part-skim mozzarella keeps costs down, and the panko adds texture without breaking the bank. I make a big tray on Sunday, and by Wednesday, I’m still eating it—because it’s that satisfying. Plus, the flavors only get better the next day, so you’re not stuck with sad, dry pasta.
Step-by-step instructions for baked spaghetti with mozzarella cheese
Here's how to create a restaurant-quality pasta bake that's crispy on top and gooey inside.
Cook the Spaghetti to Perfect Al Dente
Bring a large pot of water to a rolling boil and add 1.5 teaspoons salt—it should taste like the ocean. Add the 12 oz spaghetti and cook until it's 1 minute shy of the package directions for al dente. This ensures it finishes cooking in the oven without turning mushy. Reserve 1 cup pasta water before draining, as we'll use it later to help the sauce cling.
Drain the spaghetti and immediately toss it with 1 tablespoon olive oil to prevent sticking. I like to do this right in the pot so the heat keeps the pasta warm and flexible for layering. The oil also helps distribute the sauce more evenly when we mix everything together.
Brown the Ground Beef (If Using)
If you're including the 1 lb ground beef, heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the beef and break it apart with a wooden spoon, cooking until it's browned and fully cooked—about 6-8 minutes. Drain any excess fat, then season with 1 teaspoon Italian seasoning, 0.5 teaspoon black pepper, and 0.5 teaspoon salt. This step adds deep, savory flavor that cuts through the richness of the cheese.
If you're skipping the beef, simply heat the 1 tablespoon olive oil in the same skillet over medium heat and set it aside for the next step. The oil will help build flavor in the garlic and marinara sauce.
Sauté Garlic and Combine Sauces
In the same skillet (with or without beef), add the 3 cloves minced garlic and sauté for 30 seconds until fragrant—don't let it brown, or it'll turn bitter. Pour in the 2.5 cups marinara sauce and stir to combine. Let the sauce simmer for 3-4 minutes until it thickens slightly and the garlic flavor melds into the sauce.
Remove the skillet from heat and stir in the 2 tbsp melted butter and the 0.25 cup chopped fresh basil leaves. This adds richness and freshness that balances the tomato sauce. If the sauce is too thick, whisk in 2-3 tablespoons of the reserved pasta water to loosen it to a pourable consistency.
Layer and Assemble the Pasta Bake
Preheat your oven to 375°F and grease a 9x13-inch baking dish with 1 tablespoon olive oil—this prevents sticking and makes cleanup easier. Spread half of the cooked spaghetti evenly across the bottom of the dish. If using beef, divide it evenly over the pasta, followed by half of the marinara sauce mixture. Sprinkle 8 oz of the part-skim mozzarella cheese and ¼ cup of the Panko breadcrumbs over the top.
Repeat the layering process with the remaining spaghetti, sauce, 8 oz mozzarella cheese, and ¼ cup Panko breadcrumbs. The breadcrumbs will create that coveted crispy top we all love. Finish with the remaining 0.5 cup Parmesan cheese sprinkled evenly over the top for extra flavor and color.
Bake to Golden Perfection
Transfer the baking dish to the preheated oven and bake for 25-30 minutes until the top is golden brown and bubbly. The edges should look crispy, and the cheese should be fully melted with no raw spots. If the top isn't browning enough, broil for 1-2 minutes at the end, watching closely to avoid burning.
Let the baked spaghetti rest for 5-10 minutes before serving—this allows the layers to set and makes slicing easier. The dish should be hot, bubbly, and ready to serve with a crispy crust that contrasts beautifully with the creamy, cheesy interior. Enjoy immediately while it's at its best!
Pro Tips For Making Baked Spaghetti With Mozzarella Cheese
- Preheat Pan, Not Just Oven: I learned this the hard way—cold pans make soggy bottoms. Slide your baking dish into the oven while it’s heating, then dump in the spaghetti mix. The residual heat starts cooking the edges immediately, so you don’t end up with a watery mess after 20 minutes.
- Tear Mozzarella, Don’t Slice: Those perfect cubes? They’ll melt into a greasy puddle. Use your fingers to break the part-skim mozzarella into irregular chunks—about 1-inch pieces. The uneven surfaces brown faster and trap air, giving you that stretchy, gooey texture you actually want.
- Skip the Dry Pasta: Al dente spaghetti turns to mush in the oven. Cook it one minute less than package instructions, then drain and toss with a drizzle of olive oil right away. That extra moisture keeps it from drying out, and the oil prevents the sauce from turning into a glue trap.
- Toast Panko First: Sounds weird, but it works—dry-toast the panko in a separate pan for 2-3 minutes before mixing it in. The extra crunch stays crispier longer, and it won’t turn into a sad, wet paste clinging to the top. (Yes, even if you’re impatient like me.)
Storing and reheating this recipe
Refrigerator Storage
Let your baked spaghetti cool completely before storing—this prevents condensation that makes the breadcrumb topping soggy. Transfer to an airtight container with a paper towel pressed on top to absorb excess moisture.
Store in the fridge for up to 4 days, but honestly? It disappears faster than that. The first night, the flavors meld beautifully, making leftovers even more delicious. 🧀
Freezer-Friendly Tips
For longer storage, freeze portions in single-serving airtight containers (I use Glasslock containers—they’re my go-to). Label with the date and freeze for up to 2 months. When reheating, bake straight from frozen at 350°F for 40-45 minutes, covered with foil until heated through.
The texture stays crispy if you broil for 2-3 minutes at the end. ❄️
Oven Reheating
My favorite method is reheating in the oven—it preserves that crispy top. Cover loosely with foil and warm at 350°F for 15-20 minutes, then uncover and broil for 1-2 minutes to restore the golden crust.
Add a splash of water or marinara to the bottom of the dish if it looks dry. The result? Almost as good as fresh! 🔥
Microwave Hack
For quick lunches, microwave individual portions on medium power (50%) for 2-3 minutes, stirring halfway. Cover with a damp paper towel to prevent drying. If it’s too stiff, sprinkle a little pasta water or milk to loosen.
It won’t be as crispy, but it’s a lifesaver for busy days. ✨
Reviving Crispiness
If your leftovers lose their crispy edge, pop them under the broiler for 1-2 minutes with a sprinkle of Panko breadcrumbs. The heat reactivates the starches, giving you that satisfying crunch back.
A drizzle of olive oil before broiling adds extra richness. Trust me, this trick works every time. 💫

Frequently asked questions
Why does my baked spaghetti get watery when reheating?
The most common cause is overcooking the pasta initially or not draining it well. Always cook spaghetti 1 minute less than package instructions and reserve 1 cup pasta water—this helps bind the sauce during baking. For reheating, cover with foil and add a splash of pasta water or marinara to restore moisture before broiling.
Can I use regular mozzarella instead of part-skim?
Regular mozzarella works, but it's higher in moisture which can make your bake soggy. If using regular, drain it in a paper towel-lined strainer for 10 minutes before adding to the dish. For best results, stick with low-moisture part-skim mozzarella—it melts perfectly and creates that ideal creamy texture.
How do I make this dish vegetarian?
Skip the ground beef and add sautéed mushrooms, bell peppers, or roasted zucchini for texture. For extra protein, stir in 1 cup cooked lentils or ½ cup ricotta cheese mixed into the sauce. Fresh spinach or kale can also be layered between pasta for a nutrient boost. The dish still delivers that rich, cheesy satisfaction!
What's the secret to that perfect crispy top?
Three things: Panko breadcrumbs (not regular breadcrumbs), melted butter mixed into them, and baking at 375°F until golden. Toast the breadcrumbs in the butter for 2-3 minutes before sprinkling—they'll be extra crispy. For even better results, broil for 1-2 minutes at the end.
Can I double this recipe for a crowd?
Yes! Use a 9x13-inch dish for 8 servings or two 9x9-inch dishes for 6 servings each. The key is maintaining even layers—don't overfill or the center won't bake properly. For large groups, add an extra ½ cup breadcrumbs to the top to ensure crispiness. Bake times may increase by 5-10 minutes depending on your oven.
