Steps to make Green Bean Casserole from Scratch


Blanch green beans


In a large pot with boiling water, add 1 pound trimmed green beans and blanch for 5 minutes for firmer beans or 8 minutes for softer beans, then drain and set aside.


Sauté mushrooms


In a large pan over medium-high heat, add 1 tablespoon butter and 1 tablespoon oil, then add 8 ounces sliced mushrooms with a pinch of salt and black pepper. Sauté until the liquid has evaporated and mushrooms are soft and golden.


Cook onions


Move the mushrooms to one side of the pan and add 1 chopped onion. Sauté the onions over low heat for a few minutes, then stir them together with mushrooms and sauté until the onions are soft, about 6-8 minutes.


Add garlic


Add 2 minced garlic cloves and cook, constantly stirring, 30 seconds more.


Add flour


Stir in 2 tablespoons flour until the flour turns into a paste. Cook 1-2 minutes, stirring constantly, until it smells nutty. Be careful not to burn the mixture.


Add stock


Add the ½ cup chicken stock and bring to a boil over medium heat. Use a spatula to stir constantly and scrape the bottom of the pan.


Cook sauce


Stir in 1 cup heavy cream, 1 tablespoon Worcestershire sauce, 1 tablespoon soy sauce and cook over low until the sauce is creamy and gravy-like. Add salt to taste.


Add green beans


Add the blanched green beans to the mushroom sauce and stir to combine. Transfer to an oven-proof casserole dish.


Make Parmesan garlic bread crumbs


In a small bowl, combine ½ cup bread crumbs, ⅓ cup Parmesan cheese, ¼ teaspoon garlic powder, and 1 teaspoon dried parsley and sprinkle over the green bean casserole.


Heat oven

Preheat the oven to 375 °F.




Bake uncovered for 20 minutes. Then switch to broil and cook until the top is golden, about 2-3 minutes.



Serve immediately and enjoy!
