Description
Lightened up Green Bean Casserole with a homemade mushroom cream sauce and a crunchy panko onion topping—perfect for the holidays or any comforting meal.
Ingredients
- 1 tablespoon extra virgin olive oil
- 1 pound fresh green beans (can use frozen, just make sure to thaw and drain excess moisture)
Crispy Onion Topping:
- 1 tablespoon unsalted butter, divided
- 1 medium onion, small dice
- 1/2 cup Panko breadcrumbs
- 1/4 cup Parmesan cheese
- 1/8 teaspoon salt
- 1/8 teaspoon black pepper
Mushroom Cream Sauce:
- 2 tablespoons unsalted butter
- 8 ounces mushrooms, thinly sliced
- 2 cloves garlic, minced
- 3 tablespoons all-purpose flour
- 1/2 cup chicken stock
- 1 cup milk
- 1/2 cup Parmesan cheese
- Salt and pepper to taste
Instructions
1. Preheat oven to 375 degrees.
2. Add 1 tablespoon olive oil to a large skillet. Add in green beans and sauté for 3-4 minutes. Set aside. (They will still be crunchy; that is fine—they will continue to cook in the oven.)
3. Add 1/2 tablespoon of butter to the same skillet. Add onion and sauté for 2-3 minutes or until slightly tender. Set aside in a medium bowl.
4. Add the remaining 1/2 tablespoon of butter to the same skillet. Add panko and cook until golden brown and toasted, 1-2 minutes. Remove from the pan and toss with the onions along with the Parmesan cheese, salt and pepper. Set aside.
5. Heat butter in a medium saucepan. Add mushrooms and sauté for 3-4 minutes or until tender and golden brown.
6. Add garlic and sauté for 1 additional minute. Whisk in flour and stir constantly for 1 minute.
7. Slowly pour in chicken stock and milk. Allow the sauce to simmer, stirring constantly, until thickened. Season with salt and pepper to taste.
8. Toss the green beans in the mushroom sauce and spread in a 9 x 13 baking dish.
9. Top with the crispy onion panko topping. Bake for 20-25 minutes or until golden brown and warmed through.
10. Serve immediately and enjoy!
Notes
Use fresh green beans for the best texture, but thawed frozen ones work in a pinch.
You can make the mushroom sauce ahead of time and refrigerate until ready to assemble.
Swap chicken stock for vegetable stock for a vegetarian version.
The crispy onion topping adds a great crunch—make extra if you love a crispy bite on top!
Perfect for Thanksgiving, potlucks, or as a cozy weeknight side dish.
