Instructions Step by Step
Step 1: Prepare the Oven
Preheat your oven to 350°F / 175°C.
Lightly grease a 9 × 13-inch baking dish with olive oil or non-stick cooking spray.
Set aside.
Step 2: Cook the Spaghetti
Bring a large pot of generously salted water to a boil.
Add the spaghetti and cook according to the package instructions, reducing the cooking time by approximately 2 minutes.
The spaghetti should be firm and al dente, not completely soft.
Drain thoroughly.
Return the spaghetti to the warm pot and set aside.
Step 3: Brown the Ground Beef
Heat the olive oil in a large skillet over medium-high heat.
Add the diced onion and cook for approximately 3 minutes, stirring occasionally.
Add the minced garlic and cook for another 30 seconds.
Add the ground beef.
Break the beef into small pieces with a wooden spoon and cook for approximately 6–8 minutes, until browned and fully cooked.
Drain excess fat if necessary.
Step 4: Make the Meat Sauce
Add the Italian seasoning, salt, and black pepper to the cooked beef.
Pour in the marinara sauce.
Stir thoroughly to combine.
Reduce the heat to medium-low and simmer for approximately 5–10 minutes.
This short simmer allows the beef and marinara flavors to blend together.
Step 5: Prepare the Ricotta Mixture
In a small bowl, combine the ricotta cheese and beaten egg.
Whisk until smooth and creamy.
The egg helps the ricotta mixture set during baking.
Step 6: Coat the Spaghetti
Add the ricotta mixture to the warm, drained spaghetti.
Gently toss until the noodles are evenly coated.
Do not stir too aggressively, as you want to keep the spaghetti intact.
Step 7: Assemble the Casserole
Transfer the creamy spaghetti to the prepared baking dish.
Spread it into an even layer.
Pour the ground beef marinara sauce evenly over the spaghetti.
Use a spatula to distribute the sauce from edge to edge.
Step 8: Add the Cheese
Sprinkle the shredded mozzarella evenly over the meat sauce.
Add the grated Parmesan on top.
Make sure the cheese is distributed evenly so every serving gets a delicious golden topping.
Step 9: Bake
Place the uncovered casserole in the preheated oven.
Bake at 350°F / 175°C for 25–30 minutes.
The casserole is ready when the mozzarella is completely melted, bubbling around the edges, and lightly golden.
If the cheese is browning too quickly, loosely cover the dish with aluminum foil.
Step 10: Rest and Serve
Remove the baked spaghetti from the oven.
Allow it to rest for approximately 10 minutes.
This gives the creamy sauce and cheese time to settle, making the casserole easier to portion.
Garnish with freshly chopped parsley.
Serve warm.
Best Tips
Cook the Spaghetti Al Dente
The pasta continues cooking in the oven, so avoid fully cooking it during the initial boiling stage.
Use Freshly Shredded Mozzarella
Block mozzarella that you shred yourself generally melts smoothly and produces a better cheese pull.
Drain the Beef
Removing excess rendered fat keeps the casserole rich without making it greasy.
Use a Good Marinara Sauce
A flavorful marinara provides much of the character of the finished dish, so choose one you genuinely enjoy.
Don’t Overmix the Spaghetti
Gently coat the noodles with the ricotta mixture to avoid breaking the pasta.
Let It Rest
Ten minutes of resting time makes serving cleaner and helps prevent the layers from sliding apart.
Best Ingredient Options
Ground Beef
Use 85/15 or 90/10 lean ground beef for a good balance between flavor and richness.
Ground turkey or ground chicken can also be substituted.
Marinara Sauce
Homemade marinara works beautifully, but a high-quality store-bought sauce is convenient for busy nights.
Ricotta
Whole-milk ricotta creates the creamiest result.
Cottage cheese can be substituted if preferred.
Mozzarella
Freshly shredded low-moisture mozzarella is particularly convenient for achieving a beautifully melted topping.
Parmesan
Freshly grated Parmesan adds savory depth and helps create a golden crust.
Recipe Variations
🥦 Vegetable Baked Spaghetti
Add sautéed mushrooms, bell peppers, zucchini, spinach, or broccoli to the marinara sauce.
🌶️ Spicy Ground Beef Spaghetti

🧀 Extra-Cheesy Spaghetti Bake
Add an additional ½ cup of mozzarella between the spaghetti and meat sauce.
Finish with another layer of cheese before baking.
🍄 Mushroom Beef Pasta Bake
Sauté sliced mushrooms with the onion before adding the ground beef.
The mushrooms add a savory, hearty flavor.
🌿 Italian Herb Version
Add fresh basil, oregano, and parsley to the finished casserole for a fresh herb-forward flavor.
What to Serve With
🥖 Garlic Bread
Warm garlic bread is perfect for soaking up the remaining marinara and creamy sauce.
🥗 Green Salad
A crisp green salad with tomatoes, cucumber, and Italian dressing provides a refreshing contrast to the rich casserole.

Roasted broccoli adds texture and a simple vegetable component to the meal.
🫛 Green Beans

Thaw overnight in the refrigerator before baking.
For baked leftovers, divide the casserole into individual portions and place them in freezer-safe airtight containers.
Thaw overnight in the refrigerator and reheat until thoroughly hot.
Common Mistakes to Avoid
❌ Overcooking the Spaghetti
Fully cooked spaghetti can become soft and mushy after baking.
Solution: Cook it approximately 2 minutes less than the package instructions.
❌ Using Too Much Liquid
Excessively watery marinara or poorly drained pasta can result in a loose casserole.
Solution: Drain the spaghetti thoroughly and use a reasonably thick marinara sauce.
❌ Leaving Excess Fat in the Beef
Too much rendered fat can rise to the surface during baking.
Solution: Drain the beef after browning.
❌ Burning the Cheese
Cheese can brown before the casserole is fully heated.
Solution: Loosely tent the dish with foil if the top becomes too dark.
❌ Skipping the Resting Time
Serving immediately can cause the layers to separate.
Solution: Rest the casserole for approximately 10 minutes before slicing.
❌ Using Too Much Pasta
Excess pasta can absorb the sauce and make the casserole dry.
Solution: Keep the ingredient quantities balanced.
