Step‑by‑Step Instructions for Homemade Green Bean Casserole with Creamy Mushroom Sauce Step 1: Prepare the Green Beans Begin by bringing a large pot of salted water to a boil. Add fresh green beans and blanch them for about 3–5 minutes, ensuring they remain tender-crisp. Once done, immediately plunge them into an ice water bath to stop the cooking. This process helps preserve their vibrant green color and crunchy texture, setting the stage for your delicious homemade green bean casserole. Step 2: Make the Creamy Mushroom Sauce In a large skillet over medium heat, melt 2 tablespoons of butter. Sauté thinly sliced shallots and minced garlic for about 2–3 minutes until fragrant. Add in chopped mushrooms and cook for an additional 5–7 minutes until they release their moisture and brown slightly. Sprinkle in flour to create a roux, stirring constantly for about a minute. Gradually whisk in vegetable broth and milk, allowing the mixture to simmer and thicken for about 5 minutes. Step 3: Combine Ingredients In a large mixing bowl, combine the blanched green beans with the creamy mushroom sauce, mixing well to ensure each bean is coated. Add half of the grated parmesan cheese to the mixture for an extra touch of richness, then transfer it into a greased baking dish. This layered combination will ensure every bite of your homemade green bean casserole is bursting with flavor. Step 4: Prepare Fried Shallots While the casserole mixture is settling, slice remaining shallots thinly and heat oil in a frying pan over medium-high heat. Fry the shallots until they turn golden brown and crisp, about 3–5 minutes. Stir frequently to achieve even frying, then remove them from the pan and drain on paper towels. These crispy shallots will serve as a delectable topping for your casserole. Step 5: Assemble and Bake Preheat your oven to 375°F (190°C). Pour the green bean mixture into the prepared baking dish and even it out with a spatula. Top generously with the remaining parmesan cheese and the crispy fried shallots. Bake the casserole for 20–30 minutes until it’s bubbly and the top is golden brown, filling the kitchen with delicious aromas. Step 6: Serve Once baked, allow the homemade green bean casserole to cool for about 5 minutes. This resting time will help the flavors meld beautifully while making it easier to serve.
