Baked Spaghetti

1 . Stage

Heat salted water for the pasta: Put a large pot of water on the stove on high heat. Add salt to the water, about 2 tablespoons of salt for 4 quarts of water. While the pasta water is heating, continue with the next steps.

2 . Stage

Cook the sausage: Break up the sausage into clumps into a large sauté pan. Turn the heat on, to medium. Slowly cook the sausage, breaking the sausage into smaller pieces as it cooks. The slow cooking will help render the fat. Cook until the sausage is cooked through, no longer pink anywhere. Remove the sausage from the pan with a slotted spoon and set aside. Drain the fat from the pan (not into your sink or you may clog it!)

3 . Stage

Cook the onions, mushrooms, and spices: Add the chopped onions and mushrooms to the pan. Increase the heat to medium high. Cook, stirring frequently, until the onions become translucent and the mushrooms have given up some of their liquid. Add the minced garlic and red chili pepper flakes, and cook a minute more.

4 . Stage

Simmer the marinara, sausage, and seasonings: Add the marinara sauce and the 1 1/2 cups of water to the pan with the onions and mushrooms. Add the sausage back to the pan. Add the Italian seasoning and chopped parsley. Bring to a simmer and reduce the heat to a very low simmer on the lowest setting on your stovetop. Cook for 10 to 15 minutes or so while you make the pasta.

5 . Stage

Cook and drain the pasta: By this time your pasta water should be boiling. Add the pasta to the boiling water and cook, uncovered, at a rolling boil, for 5 to 6 minutes, al dente. Note that the pasta will continue to cook and absorb some of the sauce when it is in the casserole dish in the oven, so the pasta should be al dente. When ready, drain the pasta and rinse in cold water.

6 . Stage

Toss with olive oil, then eggs: Place the cooled pasta in a large bowl. Toss with olive oil, then the Parmesan, then 2 beaten eggs. It's easiest to do this with your (clean) hands.

7 . Stage

Preheat oven and prepare casserole pan: Preheat your oven to 350°F. Rub the inside of a 9x13 inch casserole dish (a Pyrex dish works great) with olive oil.

8 . Stage

Layer sauce and pasta in casserole dish: Spread 1 cup of the sauce over the bottom of the casserole dish. Place half of the pasta in an even layer in the casserole dish. Cover with half of the sauce.

9 . Stage

Add the cheeses and layer again: Dot the sauce with all of the ricotta cheese. Sprinkle half of the Mozzarella over the ricotta layer. Layer again with the remaining pasta, the remaining sauce, and the remaining mozzarella.

10 . Stage

Bake: Cover with foil and bake for 40 minutes at 350°F. Remove the foil and bake an additional 20 minutes uncovered. Remove from oven and let rest for at least 10 minutes before cutting into squares and serving. Did you love the recipe? Give us some stars and leave a comment below!
