How to Make Ultimate Green Bean Casserole
-
Cook Bacon: In a large skillet, fry the thick-cut bacon over medium heat until crispy, which should take about 8-10 minutes. Remove the bacon and set it aside, leaving the rendered fat in the skillet.
-
Sauté Vegetables: In the same skillet, add the yellow onion and cook for 4-5 minutes until it’s translucent. Next, add the garlic and fresh mushrooms, sautéing until softened and fragrant, about 3-4 minutes.
-
Make Sauce: In a saucepan, melt 4 tablespoons of butter over medium heat. Whisk in ½ cup of all-purpose flour, cooking it for 1-2 minutes. Gradually stir in 2 cups of half-and-half and 1 cup of chicken broth, simmering until the sauce thickens—around 5 minutes. Stir in 1½ cups of white cheddar cheese until melted and smooth.
-
Combine: Crumble the cooked bacon and fold it, along with the sautéed veggies, into the creamy sauce. Season the mixture with salt and pepper to your taste, then gently fold in 1 pound of blanched fresh green beans.
-
Assemble: Pour the green bean mixture into a greased 9×13 casserole dish. Evenly distribute 1 cup of French fried onions over the top for a delightful crunch.
-
Bake: Bake the casserole uncovered in a preheated oven at 350°F for 30 minutes, or until it’s bubbly and the onions are golden brown. Let it sit for 5 minutes before serving to allow the flavors to meld.
Optional: Garnish with extra crispy fried onions for added crunch.

• Maintain Green Bean Crunch: Avoid overcooking the blanched green beans; they should be tender yet still offer a delightful crunch in the casserole.
