Ingredients for baked spaghetti with mozzarella cheese
Just 13 ingredients transform simple spaghetti into a crispy, cheesy masterpiece with golden edges and gooey pulls.
| Ingredient | Amount | Notes |
|---|---|---|
| Spaghetti 🍝 | 12 oz | Cooked al dente, drained |
| Fresh Mozzarella Cheese 🧀 | 1 ½ lb | Low-moisture, sliced or torn |
| Marinara Sauce 🍅 | 1 ½ cups | High-quality, homemade or store-bought |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, for topping |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For drizzling between layers |
| Garlic Cloves 🧄 | 4 cloves | Minced, for flavor boost |
| Fresh Basil Leaves 🌿 | ¼ cup | Chopped, for garnish |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning noodles |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Red Bell Pepper 🧅 | 1 whole | Sliced, for added crunch |
| Unsalted Butter 🧈 | 2 tbsp | Melted, for drizzling |
| All-Purpose Flour 🌾 | 2 tbsp | For breadcrumb topping |
| Dried Oregano 🍃 | 1 tsp | For extra flavor depth |
The mozzarella is non-negotiable—low-moisture is key for that perfect stretch without excess moisture. Whole Foods or Trader Joe's carry excellent options, but avoid pre-shredded (it gets gummy). For the spaghetti, De Cecco or Barilla brands hold their shape best after baking. The marinara should be rich but not watery—Rao's or Victoria are my go-tos when shortcuts are needed. Fresh garlic and basil elevate this dish from good to extraordinary, so don't skip them if you've got them fresh.
No fresh mozzarella? Fresh mozzarella balls (bocconcini) work perfectly if you can find them. Short on basil? Dried oregano at half the amount adds depth without overpowering. The red bell pepper can be swapped for sautéed mushrooms if you prefer. For extra crispiness, toss the spaghetti with 1 tbsp of flour before layering—it creates a light crust. And trust me on the butter drizzle between layers—it's what makes those edges shatter like a dream.
This dish is all about timing—assemble it up to 2 hours ahead and refrigerate before baking. The cheese pulls best when served immediately after broiling, but leftovers reheat beautifully in the oven at 350°F for 10 minutes. Store any extras in an airtight container for up to 3 days—the flavors only get better overnight. For meal prep, portion into individual containers before baking to keep everything crispy when reheated.

Step-by-step instructions for baked spaghetti with mozzarella cheese
Here's how to create that perfect golden crust with gooey, stretchy cheese pulls—every time.
🍳 Step 1: Cook and Season the Spaghetti Al Dente
Boil the 12 oz spaghetti in well-salted water (it should taste like the sea) until 1 minute before the package suggests al dente. Drain immediately and toss with the 1.5 tsp Diamond Crystal kosher salt and 0.5 tsp ground black pepper. This seasoning step is crucial—it ensures every bite has balanced flavor before we add the rich cheeses.
I like to reserve 1 cup of pasta water before draining. This starchy liquid will help create a silky sauce later and prevent our baked casserole from drying out. Toss the hot spaghetti with the 2 tbsp extra-virgin olive oil to prevent sticking and add shine to the final dish.
🥘 Step 2: Build Layers for Maximum Crisp and Cheese Pulls
In a 9x13-inch baking dish, spread half of the cooked spaghetti in an even layer. This is where the magic begins—proper layering prevents a soggy bottom and ensures that crispy crust we're after. Drizzle half of the 1.5 cups marinara sauce over the noodles, then scatter half of the 1.5 lb fresh mozzarella cheese (torn into bite-sized pieces) and half of the sliced red bell pepper.
Repeat with the remaining spaghetti, sauce, and mozzarella. The key here is to distribute everything evenly—no thick spots where the cheese might melt unevenly. Press down gently on the top layer to help the flavors meld and prevent shifting during baking.
🔥 Step 3: Create the Crispy Topping and Bake to Perfection
In a small bowl, mix the 2 tbsp all-purpose flour with the 1 tsp dried oregano. Drizzle in the 2 tbsp melted unsalted butter and stir until you have a crumbly, pea-sized topping. Sprinkle this evenly over the top of the casserole, then grate the 0.5 cup parmesan cheese on top. This topping is what gives us that coveted crispy crust while adding depth of flavor.
Bake at 375°F for 25-30 minutes until the top is deep golden brown and the edges are bubbling. The cheese should be pulling away from the sides of the dish—this is your visual cue that it's ready. If it's browning too quickly, tent with foil for the last 5-10 minutes to prevent burning while still allowing the cheese to melt completely.
⏰ Step 4: Rest and Garnish for Maximum Impact
Remove the dish from the oven and let it rest for 10 minutes before serving. This resting period allows the cheese to fully set and the layers to knit together. The dish will be piping hot, so be cautious when handling it—those cheese pulls are serious business!
Before serving, garnish with the 0.25 cup chopped fresh basil leaves and the 4 cloves minced garlic cloves (sautéed in a small pan with a touch of olive oil if you prefer them warm). The basil adds freshness that cuts through the richness, while the garlic deepens the savory notes. Serve immediately with crusty bread to soak up every last bit of that cheesy goodness.
Pro Tips For Making Baked Spaghetti With Mozzarella Cheese
- Drain, Toss, Repeat: Fresh mozzarella releases water like a sad houseplant—drain it, pat it hard with paper towels, then toss it with a pinch of salt and a drizzle of olive oil before adding it to the spaghetti. This keeps your sauce from turning into a watery soup (yes, even if you think you’ve drained the pasta enough).
- Pre-Bake the Pasta: Skip the soggy bottom by pre-baking the spaghetti for 2–3 minutes less than package instructions, then toss it with olive oil right after draining. The residual heat finishes cooking it in the oven, and you’ll get that perfect al dente bite instead of mushy noodles.
- Layer Cheese Like a Pro: Don’t just dump mozzarella on top like confetti—cut it into chunks and nestle it between layers of sauce and pasta. This ensures every bite has melty cheese, not just the top crust. (Pro move: Sprinkle Parmesan on the bottom of the dish first—it’ll crisp up beautifully.)
- Bake Covered First: Start with foil tented over the dish for the first 20 minutes. This traps steam and helps the sauce cling to the noodles instead of evaporating into the air. Remove the foil for the last 5–10 minutes to get that golden, bubbly top—just don’t walk away or you’ll end up with a sad, pale casserole.
Health benefits of this baked spaghetti with mozzarella cheese
Protein-Packed Comfort
This baked spaghetti delivers a surprisingly substantial 25-30 grams of protein per serving, thanks to the combination of mozzarella, parmesan, and spaghetti. The 1.5 lb fresh mozzarella provides 30 grams of protein alone, while the 0.5 cup parmesan adds another 10 grams.
This makes it an excellent choice for post-workout meals or satisfying plant-based alternatives with added nutritional yeast. 💪
Calcium-Rich Cheese Boost
The generous amount of fresh mozzarella and parmesan provides 40% of your daily calcium needs per serving. Calcium is essential for bone health, muscle function, and even maintaining healthy blood pressure.
I've found that adding 1 tbsp nutritional yeast to the topping boosts calcium by another 20% per serving while adding a nutty flavor.
Rich in Vitamin C
Don't let the cheesy exterior fool you—the sliced red bell pepper adds a surprising 30% of your daily vitamin C per serving. Vitamin C supports immune function, collagen production, and helps your body absorb iron from plant-based foods.
For extra vitamin C, I sometimes add ½ cup cherry tomatoes to the sauce layer before baking.
Complex Carbohydrates
The 12 oz spaghetti provides 45 grams of complex carbohydrates per serving, offering sustained energy without the blood sugar spikes of refined carbs. The whole-grain pasta option (like Barilla's whole wheat spaghetti) adds 4 grams of fiber per serving, helping you feel fuller longer.
I always recommend using whole wheat pasta when possible for that extra fiber boost.
Healthy Fats for Satiety
The combination of extra-virgin olive oil and unsalted butter provides 12 grams of heart-healthy fats per serving, including monounsaturated fats that support brain function and reduce inflammation. The olive oil also contains vitamin E and antioxidants that protect your cells.
I measure my olive oil precisely—2 tbsp is perfect for balancing richness without overpowering the dish.
Meal Prep Nutrition
This dish reheats beautifully while maintaining most of its nutritional benefits, making it perfect for meal prep. The fiber from whole wheat pasta and protein from cheese help stabilize blood sugar levels throughout the day.
I portion mine into individual containers before baking—this keeps the texture perfect when reheated and makes it easy to grab a balanced meal on busy days. ✨

Frequently asked questions
Can I use pre-shredded mozzarella instead of fresh?
I don't recommend it for this recipe. Pre-shredded mozzarella contains anti-caking agents that make the cheese gummy rather than stretchy. For the best texture, use low-moisture fresh mozzarella (like bocconcini or whole balls) and tear it yourself. If you must use pre-shredded, drain it thoroughly and pat it dry with paper towels first.
Why is my baked spaghetti soggy instead of crispy?
Soggy results usually mean one of two things: either the spaghetti was overcooked or the sauce was too wet. Always cook your pasta 1 minute less than package instructions (al dente) and drain it well. For extra insurance, spread the noodles out on a baking sheet to dry slightly before layering. Also, reduce your marinara sauce by ¼ cup if it's particularly watery.
What's the best way to reheat leftovers?
Reheat in a 350°F oven for 10-15 minutes covered with foil, then broil for 2 minutes uncovered to restore crispiness. Microwaving works but will make the cheese rubbery. For meal prep, portion into individual containers before baking—this helps maintain texture when reheating. Leftovers keep well in an airtight container for 3 days.
Can I make this dish ahead of time?
Assemble the dish up to 2 hours ahead and refrigerate uncovered. When ready to bake, add 5-10 minutes to your baking time (about 35-40 minutes total) since it starts cooler. The cheese pulls beautifully when served immediately after baking, but the flavors develop overnight in the fridge.
What are some good protein additions?
Try adding 1 lb ground Italian sausage or chicken breast cooked and crumbled between layers. For vegetarian options, use white beans or mushrooms sautéed with garlic.
