    Inspired by this beloved Thanksgiving side dish enjoyed by many, our take on Homemade Green Bean Casserole with Cheese honors the classic using fresh green beans, a mushroom cream sauce, and of course, crispy fried onions. But it’s our addition of a homemade mushroom cream sauce, a spoonful of Dijon, and a panko-parm topping that makes this traditional side dish one of the newest additions to grace our Thanksgiving table.

    Serve with other holiday favorites including Brussels Sprout Caesar Salad, Twice-Baked Potatoes, Roasted Carrot and Ginger Soup, or Creamy Cauliflower Soup. 

    Ingredient List

    Ingredients to make homemade green bean casserole
    • Green beans: fresh or frozen and thawed, trim the stems before using.
    • Mushrooms: white button mushrooms or cremini are used in the recipe.
    • Garlic cloves: for the freshest flavor, use fresh whole garlic.
    • Onions: use fresh Spanish or cooking onions.
    • Olive oil: we use extra virgin olive oil for cooking, if you prefer, you can use a lighter oil.
    • Butter: salted butter is what we use in all of our recipes.
    • Flour: used to coat the onions before frying for the crispy onion topping.
    • Chicken broth
    • Heavy cream: provides richness and creaminess to the dish. Use 35% heavy cream or whipping cream.
    • Dijon mustard: adds brightness and tang to the casserole. Smooth or grainy mustard are both great options.
    • Panko Breadcrumbs: provide the best texture, however, any dry breadcrumbs will work.
    • Parmesan: Parmigiano-Reggiano, freshly grated. A little goes a long way so we prefer the real deal in all our recipes.
    • Salt: sea salt or kosher salt.
    • Pepper: freshly ground black pepper

    See the recipe card for full information on ingredients and quantities.

    Substitutions

    • Butter - butter can be replaced with any butter-like substitute such as coconut oil, vegan butter, or olive oil.
    • Cream - full-fat coconut milk will work as a replacement for the heavy cream. Half and half can be used to make the dish slightly lighter. 
    • Chicken Broth - swap with vegetable stock for a vegetarian green bean casserole.
    • Parmigiano-Reggiano - any hard cheese will work as a substitute for Parmigiano-Reggiano. Cheddar cheese is also a good alternative.

    Recipes Steps: How to Make Homemade Green Bean Casserole.

    Green Beans in ice water

    1. Blanch the beans.

    Preheat the oven to 450°F.

    Bring a large pot of salted water to a boil. Clean and trim the beans then place in the boiling water. For small beans, blanch for 2-3 minutes, and larger beans, blanch for 4-5 minutes. Meanwhile, fill a large bowl with ice-cold water. Drain and transfer the beans to the ice water and once cool, drain them and set aside.

    Recipe FAQs

    Is grean bean casserole vegetarian?

    Because our homemade green bean casserole recipe uses chicken stock, it’s not vegetarian, however, you can swap it with vegetable stock to make this dish fully vegetarian. 

    What is blanching green beans?

    Blanching is a cooking technique where you briefly immerse food in hot liquid, and then transfer it to an ice bath to stop the cooking process. This shocks the beans, resulting in a less mushy, bright green color, that you wouldn’t otherwise get from adding the beans into the casserole completely raw. 

    Can you use frozen beans?

    Yes, frozen beans will work, just skip the blanching portion of the recipe. 

    Can you make green bean casserole the night before?

    Yes. To make the casserole the night before, complete all steps, except making the cheese crumble and topping the casserole. The onions can be left out overnight in a covered bowl. The next morning, pull out the casserole, and preheat the oven to 400°F. Top the green beans with the crumble and onions then bake for 30 minutes, until the top is golden and the cream sauce is bubbling.

    Cook Time 50 minutes mins

    Ingredients
      

    For the fried onions:

    • 2 medium onions thinly sliced into rounds
    • ¼ cup all-purpose flour
    • ¼ teaspoon sea salt

    For the casserole:

    • 1½ lbs fresh green beans rinsed and trimmed
    • 4 tablespoon salted butter
    • 8 oz mushrooms sliced
    • 3 cloves garlic chopped
    • ¼ cup all-purpose flour
    • 1 ½ cups chicken broth
    • 1 ½ cups heavy cream
    • 2 tablespoon dijon mustard
    • Sea salt and fresh ground pepper

    For the Cheese Crumble:

    • 1½ cups freshly grated parmigiano-reggiano
    • 1 cup panko bread crumbs
    • 4 tablespoon salted butter room temperature

    Instructions
     

    • Preheat the oven to 450°F.
    • Bring a large pot of salted water to a boil. Clean and trim the beans then place in the boiling water. For small beans, blanch for 2-3 minutes and for larger beans, blanch for 4-5 minutes. Meanwhile, fill a large bowl with ice water. Drain and transfer the beans to the ice water and once cool, drain them and set aside.
    • In a medium bowl, toss onion rings with flour and a pinch of salt until coated. Place a large, oven-safe skillet on medium-high heat. Add the olive oil and once it is hot, spread the onions evenly in the pan. Fry for 6-7 minutes, tossing often, until lightly browned and crispy. Transfer to a plate and set aside.
    • Using the same large skillet. Melt butter on medium-high heat. Add the mushrooms, season with a good pinch of salt, and saute for 8-10 minutes, stirring occasionally, until they are deep brown and beginning to crisp.
    • Sprinkle in the flour and stir until the mushrooms are coated. Cook for 2 minutes, then pour in the chicken stock. Stir until the stock absorbs the flour, then mix in the cream and dijon. Season with fresh pepper, reduce heat, and simmer for 10 minutes, until the sauce is slightly thickened.
    • While the mushroom cream sauce is thickening, combine breadcrumbs, butter, Parmigiano, and a pinch of salt in a medium bowl. Set aside.
    • Add the blanched beans to the skillet. Using tongs, carefully toss the beans until all the ingredients are evenly distributed.
    • Sprinkle the top of the skillet with the breadcrumb topping. Arrange fried onions over top, then place the casserole in the oven to bake for 20 minutes, or until the topping is golden brown.
    • Allow to cool for a few minutes before serving family style.
