Ingredients
1 (8 ounce) package uncooked penne pasta
2 tablespoons vegetable oil
1/2 pound portobello mushrooms, thinly sliced 1/4 cup butter
1/4 cup all-purpose flour
3 cloves garlic, minced
1/2 teaspoon dried basil
1 3/4 cups milk
2 cups shredded mozzarella cheese
1 (10 ounce) package chopped spinach, thawed
Directions
1. Preheat oven to 350 F. Lightly grease a 9×13 inch baking dish.
2. Bring a large pot of lightly salted water to a boil. Place pasta in the pot, cook for 8 to 10 minutes, until al dente, and drain.
3. Heat the oil in a saucepan over medium heat. Stir in the mushrooms, cook 1 minute, and set aside. Melt the butter in the saucepan. Mix in flour, garlic, and basil. Gradually mix in milk until thickened. Stir in 1 cup cheese until melted. Remove saucepan from heat, and mix in cooked pasta, mushrooms, spinach, and soy sauce. Transfer to the prepared baking dish, and top with remaining cheese.
4. Bake 20 minutes in the preheated oven, until bubbly and lightly brown.
