Why You’ll Love This Recipe
Spaghetti casserole is the ultimate comfort food. It’s rich, filling, and full of bold flavors. Baking the spaghetti with cheese creates a slightly crispy top layer while keeping the inside soft and creamy. Plus, it’s incredibly versatile—you can customize it with your favorite ingredients, from vegetables to different cheeses.
Ingredients
For the Casserole:
- 300g spaghetti
- 1 tablespoon olive oil
- 1 small onion (chopped)
- 2 cloves garlic (minced)
- 400g ground beef (or chicken)
- 2 cups marinara sauce
- 1 teaspoon Italian seasoning
- Salt and black pepper (to taste)
- 1/2 teaspoon chili flakes (optional)
- 1 cup ricotta cheese (or cottage cheese)
- 1/2 cup sour cream
- 2 cups shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 egg
Instructions
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil. Cook the spaghetti according to package instructions until al dente. Drain and set aside.
Step 2: Prepare the Meat Sauce
Heat olive oil in a large pan over medium heat. Add chopped onion and sauté until soft and translucent. Stir in the garlic and cook for another minute.
Add the ground beef (or chicken) and cook until browned. Drain excess fat if needed. Pour in the marinara sauce, then season with Italian seasoning, salt, pepper, and chili flakes. Let the sauce simmer for 5–7 minutes to deepen the flavor.
Step 3: Make the Creamy Mixture
In a mixing bowl, combine ricotta cheese, sour cream, Parmesan cheese, and the egg. Mix until smooth and well blended. This layer adds a creamy richness to the casserole.
Step 4: Assemble the Casserole
Preheat your oven to 180°C (350°F) and grease a baking dish.
Spread a small amount of meat sauce on the bottom of the dish. Add half of the cooked spaghetti, followed by half of the creamy mixture, then a layer of meat sauce. Repeat the layers with the remaining ingredients.
Top with shredded mozzarella cheese for a golden, bubbly finish.
Step 5: Bake
Cover the casserole with foil and bake for 25 minutes. Remove the foil and bake for another 10–15 minutes, or until the cheese is melted and slightly golden on top.
Step 6: Rest and Serve
Let the casserole rest for about 10 minutes before serving. This helps it set and makes slicing easier.
Tips for the Best Spaghetti Casserole
1. Cook Pasta Just Right
Keep the spaghetti slightly firm (al dente), as it will continue cooking in the oven.
2. Don’t Skip the Egg
It helps bind the creamy layer, giving the casserole structure.
3. Use Quality Cheese
Freshly shredded cheese melts better and enhances the flavor.
4. Let It Rest Before Serving
This step prevents the casserole from falling apart when sliced.
Variations
- Vegetarian Version: Replace meat with sautéed mushrooms, spinach, zucchini, or lentils.
- Spicy Kick: Add extra chili flakes or diced jalapeños.
- Extra Cheesy: Mix cheddar or provolone with mozzarella.
- White Sauce Version: Swap marinara for a creamy Alfredo sauce.
Serving Suggestions
Spaghetti casserole pairs beautifully with:
- Garlic bread or dinner rolls
- Fresh green salad
- Roasted vegetables
It’s a complete meal on its own but even better with a few simple sides.
