Recipe Ingredients

It’s effortless to put together.  

  • Spaghetti noodles – Use your favorite brand of thin spaghetti noodles.
  • Italian sausage – Mild or hot, it’s your choice. The seasonings in Italian sausage add an extra flavor boost.
  • Seasonings – Onion, garlic cloves, Italian seasoning, fresh parsley, and red pepper flakes.
  • Marinara – Homemade or store-bought.
  • Water – This is added to keep it moist while baking.
  • Eggs – Used as a binder, just like in lasagna.
  • Cheese – Parmesan cheese or Pecorino Romano, ricotta cheese, and mozzarella cheese

How to Make Baked Spaghetti

  • Bring a large pot of water to a boil and salt it well. Cook the spaghetti according to the package instructions for al dente in the salted water. Drain the pasta and let it cool. Preheat your oven to 350°F.
  • In a large skillet over medium heat. Slowly cook the sausage (or ground beef), breaking it into smaller pieces. Cook until the sausage is cooked through, no longer pink anywhere, and lightly browned. Remove the sausage from the pan to a paper towel-lined dish.

  • Add the chopped onions to the pan. Increase to medium-high heat. Cook, stirring frequently until the onions become translucent. Add the minced garlic and red chili pepper flakes, stir, and cook a minute more.
  • Add the marinara sauce and 1 cup of water to the pan with the onions. Add the sausage back, Italian seasoning, and chopped parsley. Bring to a simmer and reduce the heat to a very low simmer. Cook for 10 to 15 minutes or so while you prepare the pasta. Season to taste with kosher salt and black pepper.

Sides to Serve

Enjoy this baked spaghetti with a simple green salad and garlic bread. This Arugula Fennel Salad would be great!

You can also serve it with freshly baked Italian Bread or plan ahead and make Overnight Focaccia.

Tips

  • Salt the pasta water. The water should taste like the sea.
  • Be sure to cook the spaghetti noodles al dente for this baked spaghetti recipe. You want them a little underdone because this dish is baked.
  • Shred your cheese. Store-bought cheese is coated in cellulose and doesn’t melt as nicely.

Variations

Instead of Italian sausage try some of the following meat suggestions.

  • Ground beef
  • Ground turkey
  • Ground chicken
  • For a vegetarian or meatless version use mushrooms, plant-based meat crumbles, or even tofu.
