A classic green bean casserole featuring tender green beans, a creamy homemade mushroom sauce, and a crispy fried onion topping. Perfect for potlucks, holidays, and comforting family dinners.

Ingredients

Scale
  • 1½ pounds fresh green beans, trimmed and cut into 2-inch pieces (or 4 cups frozen, thawed)
  • 4 tablespoons unsalted butter
  • 1 medium yellow onion, finely chopped
  • 2 cloves garlic, minced
  • 3 tablespoons all-purpose flour (use gluten-free flour if needed)
  • 8 ounces cremini or white button mushrooms, sliced
  • 1½ cups chicken or vegetable broth
  • ¾ cup heavy cream (or substitute half-and-half)
  • 1 teaspoon Worcestershire sauce
  • Salt and freshly ground black pepper, to taste
  • 1½ cups crispy fried onions (homemade or store-bought)

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Bring a large pot of salted water to a boil. Add the green beans and blanch for 4-5 minutes until just tender but still crisp. Drain well and set aside.
  3. In a large skillet, melt the butter over medium heat. Add the chopped onion and sauté until translucent, about 4 minutes. Stir in minced garlic and cook for 30 seconds until fragrant.
  4. Add the sliced mushrooms and cook until they release their moisture and begin to brown, about 6-7 minutes, stirring occasionally.
  5. Sprinkle the flour over the mushroom mixture and stir constantly for 2 minutes to cook out the raw flour taste.
  6. Gradually pour in the broth while whisking to avoid lumps. Then add the heavy cream and Worcestershire sauce. Bring to a simmer and cook until the sauce thickens, about 4-5 minutes. Season with salt and pepper to taste.
  7. In a mixing bowl, gently toss the blanched green beans with the mushroom sauce until evenly coated.
  8. Transfer the mixture to your casserole dish and spread it out evenly. Sprinkle the crispy fried onions on top.
  9. Bake uncovered for 25-30 minutes, until the edges bubble and the onion topping is golden brown and crispy.
  10. Let the casserole sit for 5 minutes after baking before serving.

Notes

Blanch green beans to prevent sogginess and maintain bright color. Toast crispy onions lightly before topping to keep them crunchy. Avoid covering casserole while baking to prevent soggy topping. Can prepare mushroom sauce and green beans ahead of time and assemble before baking.
