A creamy, from-scratch green bean casserole with a crispy onion topping, perfect for holiday gatherings.

Ingredients

Scale
  • 1.5 lbs fresh green beans, trimmed
  • 1 tbsp olive oil
  • 1 lb mushrooms, sliced
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 1/4 cup all-purpose flour
  • 1.5 cups milk
  • 1/2 cup chicken broth
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1 cup fried crispy onions

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Blanch the green beans in boiling water for 5-7 minutes. Drain and set aside.
  3. In a large skillet, heat olive oil over medium heat. Add mushrooms and onion, cook until softened, about 5-7 minutes.
  4. Add garlic and cook for 1 minute more until fragrant.
  5. Stir in the flour and cook for 1 minute, stirring constantly.
  6. Gradually whisk in the milk and chicken broth until smooth.
  7. Bring to a simmer, stirring, until the sauce thickens.
  8. Season with salt and pepper.
  9. Add the blanched green beans to the sauce and stir to combine.
  10. Pour the mixture into a 9×13 inch baking dish.
  11. Top evenly with crispy fried onions.
  12. Bake for 20-25 minutes, or until bubbly and the topping is golden brown.

Notes

  • For a make-ahead option, assemble the casserole and refrigerate. Bake an additional 10-15 minutes.
  • You can substitute dairy-free milk and broth for a dairy-free version.
  • To make your own crispy onions, thinly slice an onion, toss with flour, and fry until golden.
