How to Make It
Preheat oven to 350°.
Cook bacon in a large nonstick skillet over medium-high heat until crisp. Remove bacon from pan, reserving 1 teaspoon drippings in pan. Crumble bacon; set aside. Add mushrooms, bell pepper, onion, and garlic to pan; sauté 10 minutes or until tender. Add Creole seasoning, oregano, 1/2 teaspoon salt, and 1/4 teaspoon black pepper; cook 1 minute, stirring constantly. Add wine; bring to a boil. Cover, reduce heat, and simmer 3 minutes. Uncover and simmer 4 minutes.
Melt butter in a medium saucepan over medium heat. Add flour, stirring with a whisk. Gradually add milk, stirring with a whisk until well blended. Cook until slightly thick (about 8 minutes), stirring constantly (do not boil). Remove from heat. Add provolone, 1/2 teaspoon salt, and 1/2 teaspoon black pepper, stirring until cheese melts.
Spread 1/2 cup sauce in bottom of a 13 x 9-inch baking dish coated with cooking spray. Arrange 3 noodles over sauce; top with half of mushroom mixture and about 3/4 cup sauce. Repeat layers, ending with the noodles. Spread remaining sauce over noodles. Cover and bake at 350° for 30 minutes. Uncover; sprinkle evenly with mozzarella and bacon. Bake an additional 10 minutes. Let stand 15 minutes before serving.
