Step‑by‑Step Instructions for Homemade Green Bean Casserole with Creamy Mushroom Sauce
Step 1: Prepare Green Beans
Start by blanching the fresh or frozen green beans in a large pot of boiling salted water for 3–4 minutes until they are bright green and tender-crisp. Immediately transfer the beans to an ice water bath to halt the cooking process. Once cooled, drain them thoroughly and set aside, ready to be mixed into your delicious Homemade Green Bean Casserole.
Step 2: Make Mushroom Sauce
In a large skillet, melt 4 tablespoons of butter over medium heat. Add the sliced fresh mushrooms and sauté for 5–7 minutes until they are beautifully browned and tender. Sprinkle in the 2 tablespoons of flour, stirring continuously to form a roux, and cook for an additional minute to eliminate the raw flour taste before gradually whisking in 1–2 cups of milk until the sauce thickens to a creamy consistency.
Step 3: Season the Sauce
Once the sauce has thickened, season it with 1 teaspoon each of garlic powder and onion powder, along with salt and pepper to taste. Stir the mixture well, ensuring all seasonings are evenly distributed. This flavorful sauce will serve as the delicious foundation for your green bean casserole, ready to embrace the wonderful vegetables.
Step 4: Combine Ingredients
Gently stir the blanched green beans into the creamy mushroom sauce, ensuring each bean is well-coated. Take a moment to taste and adjust the seasoning as necessary, adding more salt or pepper if desired. This combination will bring rich flavor and a comforting texture to your Homemade Green Bean Casserole.
Step 5: Assemble Casserole
Preheat your oven to 375°F (190°C) while you prepare the casserole. Spread the green bean and mushroom mixture evenly in a greased 2-quart baking dish. Then, generously top the casserole with 1 cup of grated parmesan cheese and 1 cup of fried shallots, creating a crispy layer that will add delightful crunch when baked.
Step 6: Bake the Casserole
Place the assembled casserole in the preheated oven and bake for 20–30 minutes until it is bubbly and the top is golden brown. Keep an eye on it in the last few minutes to ensure the shallots don’t burn. Once perfectly cooked, remove the casserole from the oven and let it cool slightly before serving, allowing the flavors to meld beautifully.
How to Store and Freeze Green Bean Casserole

Homemade Green Bean Casserole with Creamy Mushroom Sauce Recipe FAQs
How do I select the best green beans?
Absolutely! Look for firm, vibrant green beans with a smooth skin and no dark spots or blemishes. The ends should be fresh and not dried out, indicating they’re just picked. If you choose frozen green beans, ensure they are free from ice crystals, which can indicate freezer burn.
What is the best way to store leftover green bean casserole?
Leftovers should be stored in an airtight container in the fridge for up to 3 days. To reheat, cover with foil and bake at 350°F (175°C) for about 20-25 minutes until warmed through. This method helps to retain the casserole’s creamy texture while preventing the shallots from burning.
Can I freeze my green bean casserole?
Definitely! To freeze an unbaked casserole, wrap it tightly in plastic wrap and then in foil to prevent freezer burn. It can be frozen for up to 2 months. When ready to use, simply thaw it overnight in the fridge and bake as directed. You may need to add a few extra minutes to the baking time if it’s still a bit chilly when placed in the oven.
What if my sauce isn’t thickening properly?
Very! If you find that your sauce isn’t thickening as expected, sprinkle in a little more flour mixed with a splash of cold milk to create a slurry. Whisk it continuously into the simmering sauce until it reaches your desired consistency. Just give it a minute or two to thicken, as the heat will help activate the flour.
Are there any dietary considerations for this casserole?
Yes! If you’re catering to dietary restrictions, you can make a dairy-free version by substituting the butter and milk with olive oil and almond or coconut milk. Additionally, for those with gluten allergies, opt for a gluten-free flour blend when making your roux. Always check ingredient labels to ensure they meet your guests’ needs, especially for allergies.
