Step‑by‑Step Instructions for Homemade Green Bean Casserole with Creamy Mushroom Sauce
Step 1: Prepare the Fried Shallots
Begin by thinly slicing two shallots and dredging them in flour until evenly coated. Heat a skillet over medium heat and add enough oil to cover the bottom. Fry the shallots for about 5-7 minutes, stirring occasionally until they turn golden brown and crispy. Once done, transfer them to a paper towel to drain excess oil, setting aside for later.
Step 2: Blanch Green Beans
Bring a large pot of salted water to a rolling boil while simultaneously preparing an ice bath in a large bowl. Add the fresh green beans and blanch them for 3-4 minutes, just until they are bright green and tender-crisp. Immediately transfer the beans to the ice bath to stop the cooking process and preserve their vibrant color; drain and set aside.
Step 3: Make the Mushroom Sauce
In the same skillet, melt 2 tablespoons of butter over medium heat, then add about 8 ounces of sliced mushrooms. Sauté the mushrooms for about 5-6 minutes until they release their juices and become golden brown. Add minced garlic and cook for an additional minute until fragrant, then pour in 1 cup of heavy cream, seasoning with salt and pepper. Stir well and let it simmer gently for 3-4 minutes until slightly thickened.
Step 4: Combine Ingredients
In a large mixing bowl, combine the blanched green beans with the creamy mushroom sauce. Add half of the crispy fried shallots to the mixture, stirring gently to coat the beans evenly. Carefully transfer the entire mixture into a greased baking dish, ensuring even distribution of the green beans and sauce.
Step 5: Top and Bake
Preheat your oven to 375°F (190°C). Sprinkle the remaining crispy fried shallots on top of the casserole, followed by a generous dusting of freshly grated Parmesan cheese. Bake the assembled green bean casserole for 20 minutes, or until the top is bubbly and golden brown. Enjoy the warm, comforting aroma as it fills your kitchen!

How to Store and Freeze Green Bean Casserole

Expert Tips for Green Bean Casserole
-
Blanching Bliss: Always plunge green beans into ice water after boiling. This method stops cooking and retains their vibrant color and crispness, elevating your green bean casserole.
-
Perfect Frying: Ensure your oil is at medium heat when frying shallots. Too hot, and they’ll burn; too low, and they’ll absorb oil instead of getting crispy.
-
Creamy Consistency: When making the mushroom sauce, allow it to simmer gently; avoid boiling. This step ensures a rich and creamy sauce, perfectly melding with your green beans.
-
Season to Taste: Taste your creamy mushroom sauce before mixing with the green beans. Adjust salt and pepper as needed to achieve a flavor that impresses everyone.
-
Make-Ahead Magic: Assembling your casserole up to 2 days in advance is a great time-saver. Cover tightly and refrigerate; then bake when the holiday hustle begins!

Homemade Green Bean Casserole Recipe FAQs
What are the best green beans to use for this casserole?
Absolutely! Fresh green beans are ideal for this dish as they provide a crunchy texture. Look for beans that are bright green and free of dark spots. If you can’t find fresh ones, frozen green beans work well too—just thaw and drain them before using.
How should I store leftovers from the casserole?
You can store leftover green bean casserole in an airtight container in the fridge for up to 5 days. To retain the best texture, reheat it in the oven until warmed through, rather than microwaving.
Can I freeze green bean casserole?
Very! To freeze, portion the casserole into freezer-safe containers. It’s best used within 2-3 months. For reheating, I recommend defrosting it in the fridge overnight and baking at 350°F until heated through to maintain that delightful crunch from the shallots.
What can I do if my casserole turns out too watery?
If your green bean casserole is too watery, don’t worry! There are ways to fix this. First, make sure to cook your mushroom sauce down until it thickens before combining it with the beans. If it’s already mixed, you can add a bit more cooked flour or cornstarch to thicken it. Simply whisk a tablespoon of cornstarch with a little cold water until smooth, then stir it back into the casserole and return it to the oven until it sets.
Is there a way to make this dish allergy-friendly?
Of course! This recipe can easily be made dairy-free and vegan by substituting heavy cream with a dairy-free cream alternative and replacing Parmesan cheese with nutritional yeast. Just make sure to check that your fried shallots don’t contain any allergens and you’re all set for everyone at the table to enjoy!
Can I make this casserole in advance?
