Ingredients

Scale
  • 4 cups fresh green beans, trimmed and cut
  • 1 tablespoon olive oil
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 8 ounces mushrooms, sliced
  • 1 cup heavy cream
  • 1 cup chicken or vegetable broth
  • 1 teaspoon soy sauce

Instructions

  1. Preheat the oven to 350°F (175°C).
  2. Blanch the green beans in boiling water for 3-4 minutes until tender-crisp, then drain and set aside.
  3. In a skillet, heat olive oil over medium heat. Add onions and garlic; sauté until translucent.
  4. Add mushrooms and cook until they release their moisture and become tender.
  5. Pour in heavy cream and broth, stir in soy sauce, and simmer until the sauce thickens, about 5 minutes.
  6. Season the mushroom sauce with salt and pepper to taste.
  7. Combine the green beans and mushroom sauce, then transfer to a baking dish.
  8. Sprinkle crispy fried onions evenly over the top.
  9. Bake for 20-25 minutes until the casserole is bubbly and the onions are golden brown.
  10. Remove from oven and let rest for 5 minutes before serving.

Notes

For extra flavor, try adding a sprinkle of shredded cheddar cheese under the fried onions before baking.
