Cheesy Mushroom Baked RigatoniPrint This
- 1 pound rigatoni pasta
- 1 tablespoon olive oil
- 10 ounces Baby Bella mushrooms, sliced
- 1 small shallot diced
- 2 cloves garlic, minced
- 3 tablespoons butter
- 3 tablespoons all purpose flour
- 3 cups whole milk
- 1½ cups shredded gruyere cheese, divided
- 1 cup grated parmesan cheese, divided
Preheat the oven to 350 degrees.
Reserve ½ cup of the shredded gruyere cheese and ½ cup of the grated parmesan cheese. They will be sprinkled on top of the pasta before baking.
Bring a large pot of water to a boil over high heat to cook the rigatoni. Cook the rigatoni for 2 minutes less than the instructions on the package for al dente. The pasta will continue to cook during the baking process.
Heat the olive oil in a large skillet over medium low heat. Add the mushrooms and cook, stirring occasionally for 5 minutes or until they have released all of their liquid.
Add the shallots and onions to the skillet and cook for an additional 2 minutes, stirring occasionally.
When the pasta is done, drain and rinse it. Set aside.
Add the butter to the large pasta pot and melt over medium low heat. Add the flour and whisk it constantly until it completely combines with the butter.
Slowly add the milk, whisking constantly. Make sure that the flour mixture is being totally incorporated and the mixture is smooth. You must keep whisking in order to achieve this.
Raise the heat to medium and continue to whisk the flour and milk mixture until it begins to boil and bubble. Continue to whisk for an additional minute as the boiling will thicken the sauce.
Turn off the heat and return the pasta to the pot with the sauce.
Stir in the mushroom mixture, 1 cup of the gruyere cheese and ½ cup of the parmesan cheese. Combine well.
Spoon the mixture into a 9″ x 13″ baking pan that has been lightly greased with butter or sprayed with cooking spray. Spread it evenly and make sure that the top is smooth.
Sprinkle the remaining gruyere and parmesan cheese evenly over the top of the pasta.
Bake for 20- 25 minutes until it is heated through and the cheese has melted.
