Description

Easy Green Bean Casserole: A fresh twist on the Thanksgiving classic with a homemade creamy mushroom sauce and crispy fried onions for crunch.


Ingredients

Scale
  • 1 1/2 pounds fresh green beans, trimmed and halved
  • 2 tbsp butter
  • 1 small onion, finely chopped
  • 8 oz fresh mushrooms, sliced
  • 2 tbsp all-purpose flour
  • 3/4 cup milk
  • 1/2 cup vegetable broth
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1 cup shredded cheddar cheese (optional for cheesy version)
  • 1 1/2 cups french fried onions, divided

Instructions

  1. Preheat oven to 375°F (190°C).
  2. Boil green beans in salted water for 4–5 minutes until tender-crisp. Drain and rinse under cold water to stop cooking.
  3. In a large skillet, melt butter over medium heat. Add onions and mushrooms, sautéing until softened and golden, about 8–10 minutes.
  4. Sprinkle flour over the vegetables and stir for 1 minute to cook off the raw taste.
  5. Slowly whisk in milk and broth, stirring until the sauce thickens, 3–5 minutes. Season with salt and pepper.
  6. Optional: Stir in shredded cheddar cheese for a creamy, cheesy twist.
  7. Combine green beans with the sauce and mix well.
  8. Transfer to a baking dish, top with 1 cup of fried onions, and cover with foil.
  9. Bake for 25 minutes, then uncover and top with remaining fried onions.
  10. Bake another 10–15 minutes until bubbly and golden. Let rest a few minutes before serving.

Notes

  • Do I drain my green beans for green bean casserole? Yes—drain and rinse under cold water to stop cooking.
  • Can you use heavy cream instead of milk in green bean casserole? The recipe uses milk; heavy cream is not specified. If you choose to use heavy cream, the sauce will be richer; consider diluting with extra broth to balance thickness.
  • How long does green bean casserole take in the oven? Bake times are 25 minutes with topping, then 10–15 minutes more until bubbly and golden (total oven time ≈ 35–40 minutes).
