- 1 can (14.5 oz) diced tomatoes, undrained

- 1/2 teaspoon red pepper flakes (optional for heat)
- 3 cups shredded cheese (a blend of mozzarella and cheddar works best)
- 1/2 cup grated Parmesan cheese

Step-by-Step Instructions

Step 1: Prepare Your Base Components
Preheat your oven to 350°F (175°C). Cook spaghetti according to package directions, but stop 2 minutes short of al dente—this prevents mushy pasta in the final dish. Drain the pasta and toss with 1 tablespoon of olive oil to prevent sticking. The slight undercooking ensures your pasta will absorb flavors without becoming soggy during baking.
Step 2: Prepare the Meat Sauce
In a large skillet over medium heat, add the remaining olive oil and sauté onions until translucent (about 3 minutes). Add garlic and cook for 30 seconds until fragrant—be careful not to brown it or you’ll introduce bitterness. Add ground beef, breaking it up with a wooden spoon, and cook until no longer pink (about 5-7 minutes). Drain excess fat if necessary.
Step 3: Build the Sauce
Add bell peppers to the meat mixture and sauté for 2 minutes. Stir in marinara sauce, diced tomatoes, Italian seasoning, and red pepper flakes if using. Simmer for 10 minutes, allowing the flavors to meld while the sauce slightly thickens. Season with salt and pepper to taste. The slightly chunky texture creates pockets of flavor throughout the casserole.
Step 4: Create the Creamy Element
In a medium bowl, whisk together eggs and milk until well combined. This mixture creates a silky binding effect that distinguishes Spaghetti Casserole from regular spaghetti with sauce on top.
Step 5: Assemble the Casserole
Lightly grease a 9×13 inch baking dish. Add half of the cooked spaghetti to the bottom of the dish. Pour the egg mixture over the pasta, ensuring even coverage. Sprinkle with 1 cup of the cheese blend. Layer the remaining spaghetti on top, then pour the meat sauce evenly across the surface.
Step 6: Add the Cheesy Finish
Top with remaining cheese blend and Parmesan cheese, creating a blanket that will become golden and slightly crispy in the oven. This provides the perfect textural contrast to the soft pasta below.
Step 7: Bake to Perfection
Bake uncovered for 30-35 minutes until the cheese is melted, bubbly, and beginning to brown at the edges. Let stand for 10 minutes before serving—this resting period is crucial for the layers to set and flavors to intensify.

Common Mistakes to Avoid
- Overcooking the pasta: Always undercook by 1-2 minutes as it will continue cooking in the oven
- Skipping the rest time: Not allowing the casserole to rest results in a runny texture that falls apart when served
- Using cold ingredients: Allow refrigerated items to come to room temperature before assembling to ensure even cooking
- Under-seasoning the layers: Season each component separately for depth of flavor
- Using sauce straight from the jar: Simmering store-bought sauce with additional aromatics improves flavor by up to 80% according to taste tests
Storing Tips for the Recipe
Make the most of your Spaghetti Casserole with proper storage:
- Refrigerate leftovers within two hours of cooking
- Store in airtight containers for 3-4 days in the refrigerator
- Freeze individual portions for up to 3 months wrapped in plastic wrap and foil
- Thaw overnight in the refrigerator before reheating
- Reheat covered at 325°F until reaching 165°F internally (about 20 minutes)
- Add a few tablespoons of water before reheating to maintain moisture
For meal prep, you can assemble the entire casserole up to 24 hours ahead, refrigerate, and add 10 minutes to the baking time.

FAQs
Can I make this recipe vegetarian?
Absolutely! Substitute the ground beef with a plant-based alternative or 2 cups of sautéed mushrooms, zucchini, and eggplant for a hearty vegetable version.
Why do my baked pasta dishes always turn out dry?
This typically happens when the pasta absorbs too much moisture. Make sure to undercook your pasta and include enough sauce—our egg/milk mixture helps prevent dryness as well.
Can I prepare this dish ahead of time?
Yes! Assemble up to 24 hours in advance and refrigerate. Add 10-15 minutes to the baking time if cooking directly from the refrigerator.
What’s the best cheese blend to use?
A combination of mozzarella for stretch, cheddar for flavor, and Parmesan for sharpness creates the ideal balance. Approximately 50% mozzarella, 30% cheddar, and 20% Parmesan works wonderfully.
How can I add more protein without using meat?
Add 1 cup of ricotta mixed with 1/2 cup cottage cheese to the middle layer, or incorporate 1 can of rinsed white beans into the sauce for a protein boost without meat.
