Cheesy Baked Spaghetti Casserole

Transform everyday spaghetti into a mouthwatering casserole that layers pasta with a robust meat sauce and generous cheese fillings. This dish captures the essence of Italian comfort food, blending al dente noodles, tangy tomato sauce infused with herbs, and a trio of cheeses for creamy, melty perfection. Ideal for feeding a crowd or meal prepping, it bakes to bubbly goodness in under an hour.

Why This Recipe Stands Out

Baked spaghetti elevates simple ingredients into a family favorite. Unlike stovetop pasta, baking allows flavors to meld, creating a lasagna-like texture without the hassle of multiple noodle layers. The meat sauce simmers with aromatics for depth, while ricotta and parmesan provide creaminess that contrasts the stretchy mozzarella top. It’s versatile—use ground beef, sausage, or turkey—and freezes beautifully for later.

Prep time is minimal: about 20 minutes, followed by 40-45 minutes of baking. Serves 8-10 generously, making it economical for gatherings. Leftovers reheat well, maintaining moisture thanks to the egg-enriched pasta base.

Essential Ingredients Breakdown

Gather these pantry staples and dairy for success. Quantities yield a 9×13-inch dish.

• Pasta: 1 pound spaghetti, broken into halves for even layering.
• Protein: 1.5 pounds ground beef or Italian sausage (90% lean to reduce grease).
• Aromatics: 1 medium onion (diced), 3 garlic cloves (minced).
• Sauce base: 24 ounces marinara, one 15-ounce can diced tomatoes (undrained), 2 tablespoons tomato paste.
• Seasonings: 2 teaspoons Italian seasoning, 1 teaspoon salt, ½ teaspoon black pepper.
• Cheese layers: 1 cup ricotta, ¾ cup grated parmesan (divided), 2 cups shredded mozzarella (divided), ½ cup sour cream (optional for extra creaminess).
• Binders: 1 egg (lightly beaten), 2 tablespoons olive oil or melted butter.
• Garnish: Fresh parsley or basil, chopped.

Pro tip: Opt for no-boil pasta if short on time, but adjust liquid in sauce accordingly.

Step-by-Step Preparation Guide

Follow these instructions for foolproof results. Preheat oven to 350°F early.

1. Cook the pasta: Boil spaghetti in salted water 1-2 minutes less than package (al dente). Drain, return to pot off heat. Toss with olive oil, beaten egg, and ½ cup parmesan to coat and prevent sticking.
2. Build the sauce: In a large skillet over medium heat, brown meat with onion until no pink remains (8-10 minutes). Drain excess fat. Add garlic, Italian seasoning, salt, pepper; stir 1 minute. Stir in tomato paste, marinara, diced tomatoes. Simmer 5-7 minutes, allowing flavors to intensify.
3. Prepare cheese mix: In a bowl, combine ricotta, remaining parmesan, sour cream (if using), and a pinch of pepper. Mix until smooth for dolloping.
4. Assemble layers: Grease a 9×13 baking dish. Spread half the pasta mixture. Top with half the sauce, then dollop all ricotta mixture evenly. Add remaining pasta, sauce, 1 cup mozzarella.
5. Bake to perfection: Cover with foil. Bake 30 minutes. Uncover, sprinkle remaining mozzarella and parmesan. Bake 10-15 more minutes until cheese bubbles and browns. Rest 10 minutes before slicing.

Total time: 60-70 minutes. Let it cool slightly for clean cuts.

Storage, Freezing, and Reheating Tips

This casserole shines in make-ahead scenarios.

• Fridge: Covered, up to 4 days. Reheat slices in microwave (2-3 minutes) or oven at 350°F for 15-20 minutes.

• Make-ahead: Assemble fully, refrigerate up to 24 hours before baking. Increase initial bake time by 10 minutes if cold.

Portion into meal prep containers for grab-and-go lunches.
