Ingredients

The following ingredients have 7 Servings
  • 1 + 1/2 lbs. green beans, ends trimmed and cut in half
  • 1/4 cup butter
  • 1 medium onion, sliced
  • 3 cups brown mushrooms, sliced (about 1/2 lb.)
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 2 tablespoons garlic, minced
  • 2 tablespoons all-purpose flour
  • 2 cups heavy cream (or half and half cream)
  • 1/2 teaspoon Italian seasoning 
  • 1/4 teaspoon cayenne pepper (optional)
  • 1/4 cup Parmesan cheese, grated
  • 1 + 1/2 cups French fried onions, homemade or store-bought

Instruction

  • Preheat oven to 350 F.
  • In a large pot of boiling water, add green beans and blanch until slightly softened yet still bright green, about 5 minutes. Rinse green beans under running cold water to cool off and drain in a colander. Set aside.
  • In a large skillet, melt butter over medium-high heat for 1 minute. Add onion and mushrooms and season with salt and pepper. Sauté, stirring occasionally, for 5-7 minutes until nicely browned on all sides.
  • Add garlic and cook until fragrant, about 1 minute. Stir in flour until evenly combined and cook for another minute.
  • Add heavy cream, Italian seasoning, cayenne (if using), and Parmesan cheese. Stir well and bring the sauce to a simmer. Reduce heat to medium and keep stirring until thickened to the desired consistency, about 5-7 minutes. Turn off the heat and set aside.
  • Place green beans in a 9x13-inch casserole pan and pour cream sauce evenly on top. Bake at 350 F until golden brown, about 25 minutes.
  • Sprinkle fried onions on top and bake for another 5 minutes until crispy. Let cool for 5-10 minutes and serve warm.
