Description
A classic green bean casserole made with tender green beans, creamy mushroom sauce, and crispy fried onions baked to golden perfection. A staple side dish for holidays or family dinners.
Ingredients
- 4 cups fresh or frozen green beans, trimmed and cut into 2-inch pieces
- 2 tbsp butter
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 8 oz mushrooms, sliced
- 2 tbsp all-purpose flour
- 1 cup chicken or vegetable broth
- 1 cup whole milk
- 1/2 cup heavy cream (optional for extra creaminess)
- 1 tsp salt
- 1/2 tsp black pepper
- 1/4 tsp nutmeg (optional)
- 1 1/2 cups crispy fried onions, divided
- 1 cup shredded cheddar cheese (optional)
Instructions
- Preheat oven to 375°F (190°C).
- Bring a large pot of salted water to a boil. Add green beans and blanch for 3–4 minutes until bright green and slightly tender. Drain and set aside.
- In a large skillet, melt butter over medium heat. Add onions and mushrooms and cook until softened, about 5 minutes. Add garlic and cook for 1 more minute.
- Sprinkle flour over the vegetables and stir well to coat. Cook for 1–2 minutes.
- Gradually whisk in broth and milk, stirring constantly until the sauce thickens, about 5 minutes.
- Stir in salt, pepper, nutmeg, and heavy cream (if using). Remove from heat and mix in the green beans and half of the crispy onions. Add cheddar cheese if desired.
- Transfer mixture to a baking dish and spread evenly.
- Top with the remaining crispy fried onions.
- Bake uncovered for 20–25 minutes until bubbly and golden brown on top.
Notes
- For a lighter version, skip the heavy cream and use only milk.
- You can substitute canned cream of mushroom soup for the homemade sauce if short on time.
- Use fresh green beans for the best texture and color.
