Butternut Squash Au Gratin With Wild Mushrooms And Crispy Bacon

• 1 tablespoon extra-virgin olive oil
• 2 thinly sliced green onions
• 8 cups finely diced peeled butternut squash, divided (about 4 pounds)
• 1/2 teaspoon kosher salt, divided
• 2 center-cut bacon slices
• 4 ounces sliced chanterelle mushrooms
• 4 ounces sliced shiitake mushroom caps
• 1 1/2 tablespoons chopped fresh sage
• 1/4 cup unsalted beef stock (such as Swanson)
• 2 ounces Parmigiano-Reggiano cheese, grated and divided (about 1/2 cup)
• 2 tablespoons part-skim ricotta cheese
• 1/4 teaspoon freshly ground black pepper
• Cooking spray
• 6 ounces oyster mushrooms, sliced

1. Preheat oven to 350u0b0.
2. Heat a large skillet over medium-high heat. Add oil; swirl to coat. Add green onions; saute 30 seconds. Add 6 cups squash; saute 2 minutes. Reduce heat to medium-low, and stir in 1/4 teaspoon salt. Cook, covered, 15 minutes or until tender. Increase heat to medium-high. Cook, uncovered, 2 minutes or until liquid evaporates, stirring frequently. Place squash mixture in a large bowl; mash with a potato masher or fork until smooth.
3. Cook bacon in a large nonstick skillet over medium-high heat until crisp. Remove bacon from pan, reserving drippings in pan; crumble bacon. Add chanterelles, shiitakes, and sage to drippings; saute 8 minutes or until mushrooms are browned. Add stock; cook 3 minutes or until liquid almost evaporates. Add mushroom mixture, remaining 2 cups diced squash, remaining 1/4 teaspoon salt, 1 ounce Parmigiano--Reggiano cheese, ricotta cheese, and black pepper to mashed squash mixture, stirring to combine. Spoon squash mixture into a broiler-safe 11 x 7-inch glass or ceramic baking dish coated with cooking spray. Cover with foil; bake at 350u0b0 for 1 hour. Remove pan from oven; discard foil.
4. Preheat broiler to high.
5. Combine bacon, remaining 1 ounce Parmigiano-Reggiano, and oyster mushrooms in a bowl; sprinkle over gratin. Broil 6 minutes or until lightly browned. Let stand 5 minutes before serving.
