Cheesy Layered Baked Spaghetti Casserole: A Taste of Home

This dish takes me right back to Sunday dinners at my grandmother’s. The aroma of simmering tomato sauce, infused with oregano and garlic, would fill the entire house. This casserole, bubbling with cheese and boasting layers of perfectly cooked spaghetti, was always the star of the show. Every bite was a comforting symphony of flavors, a reminder of family, love, and the simple joys of a home-cooked meal. It’s a tradition I’ve happily carried on, and I’m thrilled to share it with you.

• 1/2 cup sliced green olives (optional, can use a bit more)
• 1 (28 ounce) can crushed tomatoes
• 1 (14 ounce) can crushed tomatoes
• Salt and black pepper, to taste
• 3 cups grated mozzarella cheese, divided (can use more or less)
• 2 (10 ounce) cans cream of mushroom soup, undiluted

Equipment Needed

• Lasagna baking pan
• Large bowl
• Medium heavy pot
• Baking sheet

Instructions

1. Preheat your oven to 375 degrees F (190 degrees C). Grease a lasagna baking pan.

2. In a large bowl, combine the cooked spaghetti with salt, pepper, eggs, and 3/4 cup of grated Parmesan cheese. Toss well to ensure the spaghetti is evenly coated. Set aside.

3. Prepare the meat sauce: In a medium heavy pot, brown the ground beef and ground pork over medium-high heat. Add the dried oregano, dried basil, chili flakes, chopped onion, green bell pepper, jalapeno pepper (if using), minced garlic, and drained mushrooms.

4. Cook until the beef and pork are browned and the vegetables are tender, approximately 12-15 minutes. Drain any excess fat.

5. Stir in the sliced green olives (if using), the 28-ounce can of crushed tomatoes, and the 14-ounce can of crushed tomatoes.

6. Simmer uncovered for approximately 45 minutes, allowing the sauce to thicken and the flavors to meld.

7. Season the sauce with salt and pepper to taste. At this point, you can cool the sauce to room temperature and refrigerate it for up to 2 days to allow the flavors to further develop. This step is highly recommended for the best flavor!

8. Spread half of the spaghetti mixture evenly in the bottom of the prepared baking dish.

9. Top with half of the meat sauce, followed by about 1 1/2 cups of mozzarella cheese.

10. Repeat the layers: Spread the remaining spaghetti over the cheese, then top with the remaining meat sauce, and finally, the remaining mozzarella cheese.

11. Sprinkle the chopped green bell pepper evenly over the top of the mozzarella cheese.

12. In a separate bowl, whisk together the cream of mushroom soup with the milk or water until smooth.

13. Drizzle the soup mixture evenly over the entire casserole.

14. Sprinkle the remaining 1/3 cup of Parmesan cheese (or more, to taste) on top. The pan will be quite full, so I recommend placing the baking dish on a baking sheet to catch any spills during baking.

15. Bake in the preheated 375-degree F (190 degrees C) oven for 35-40 minutes, or until the casserole is bubbly and the cheese is melted and lightly golden brown. If desired, sprinkle additional mozzarella cheese on top during the last 5 minutes of baking for an extra cheesy finish.

Expert Tips & Tricks

• For a deeper, richer flavor, use a combination of Italian sausage and ground beef in your meat sauce.
• Don’t overcook the spaghetti! Al dente pasta holds its shape better during baking and prevents a mushy casserole.
• If the top of the casserole is browning too quickly, tent it loosely with aluminum foil during the last 10-15 minutes of baking.
• For an extra layer of flavor, add a dollop of ricotta cheese between the spaghetti and meat sauce layers.
• To prevent the spaghetti from sticking together while waiting to assemble the casserole, toss it with a little olive oil after cooking.

Serving & Storage Suggestions

Allow the Cheesy Layered Baked Spaghetti Casserole to cool slightly before serving. This helps the layers set and prevents the casserole from falling apart when you cut into it. Garnish with a sprig of fresh basil or parsley for a pop of color.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, cover the casserole with foil and bake in a preheated 350-degree F (175 degrees C) oven until heated through, about 20-30 minutes. You can also reheat individual portions in the microwave.

For longer storage, the casserole can be frozen for up to 2-3 months. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. Thaw in the refrigerator overnight before reheating.

FAQs (Frequently Asked Questions)

Q: Can I make the meat sauce ahead of time?
A: Absolutely! In fact, making the meat sauce a day or two in advance allows the flavors to meld and deepen, resulting in a more flavorful casserole. Just store it in the refrigerator until you’re ready to assemble the dish.

Q: Can I use a different type of cheese?
A: Yes, feel free to experiment with different cheeses! Provolone, fontina, or a blend of Italian cheeses would all work well in this casserole.

Q: Can I freeze the assembled casserole before baking?
A: Yes, you can freeze the assembled casserole before baking. Wrap it tightly in plastic wrap and then in foil. Thaw it in the refrigerator overnight before baking as directed.

Q: My casserole is getting too brown on top. What should I do?
A: If the top of the casserole is browning too quickly, tent it loosely with aluminum foil during the last 10-15 minutes of baking.

Q: Can I use fresh tomatoes instead of canned?
A: Yes, you can use fresh tomatoes. You’ll need about 4-5 cups of chopped fresh tomatoes. Simmer them in the sauce for a longer period to allow them to break down and create a flavorful sauce.
