Italian Sausage Baked Spaghetti
This Baked Spaghetti brings serious comfort-food energy! Tender spaghetti is layered with Italian sausage marinara, creamy ricotta, Parmesan, and lots of mozzarella, then baked until hot, bubbly, and beautifully cheesy.
🛒 Ingredients
- ¾ lb vermicelli pasta or thin spaghetti
- 1 lb sweet Italian pork sausage, casings removed
- ¼ lb shiitake or cremini mushrooms, roughly chopped
- 1 medium onion, chopped, about 1½ cups
- 2 garlic cloves, minced
- ¼ tsp red pepper flakes
- 3 cups (24 oz) marinara sauce
- 1½ cups water
- 1 Tbsp Italian seasoning
- ¼ cup fresh parsley, chopped
- 1 Tbsp extra virgin olive oil, plus more for greasing
- 1 cup grated Parmesan cheese
- 2 large eggs, beaten
- 1 cup ricotta cheese
- 2–3 cups shredded mozzarella cheese
👩🍳 Directions
Brown the Italian sausage in a large skillet over medium heat, breaking it into small crumbles as it cooks. Remove from the skillet and drain the excess fat.
Cook the onion and mushrooms until tender. Add the garlic and red pepper flakes and cook briefly.
Stir in the marinara sauce, water, cooked sausage, Italian seasoning, and parsley. Simmer gently for 10–15 minutes.
Cook the spaghetti in salted boiling water for 5–6 minutes until al dente. Drain and cool slightly.
Toss the spaghetti with olive oil, Parmesan, and beaten eggs.
Preheat the oven to 350°F and grease a 9×13-inch casserole dish with olive oil.
Spread 1 cup of sauce over the bottom of the baking dish.
Layer half of the spaghetti over the sauce, followed by half of the remaining meat sauce.
Add spoonfuls of ricotta and sprinkle with half of the mozzarella.
Layer the remaining spaghetti and sauce on top.
Finish with the remaining mozzarella.
Cover with foil and bake for 40 minutes.
Uncover and bake for another 20 minutes, until golden, melted, and bubbling.
Let the baked spaghetti rest for at least 10 minutes before cutting and serving.
