Step‑by‑Step Instructions for Homemade Green Bean Casserole
Step 1: Prep the Green Beans
Bring a large pot of water to a rolling boil and carefully add your fresh green beans. Blanch them for 3-4 minutes until they turn vibrant green and are tender-crisp. Immediately transfer the beans to a bowl of ice water to halt the cooking process, ensuring they retain their bright color and crunch. Drain and set aside.
Step 2: Make the Creamy Mushroom Sauce
In a large skillet, melt 4 tablespoons of butter over medium heat. Add sliced mushrooms, minced garlic, and fresh thyme, sautéing for about 5-7 minutes until the mushrooms soften and release their juices. Sprinkle in ¼ cup of flour, stirring continuously for 1-2 minutes until forms a roux, then gradually whisk in 2 cups of cream (or plant-based milk) until the sauce thickens and becomes velvety, about 3-5 minutes.
Step 3: Combine Ingredients
Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the blanched green beans with the creamy mushroom sauce and half of the grated Parmesan cheese, stirring well to coat everything evenly. Transfer the mixture into a greased 9×13-inch baking dish, spreading it out evenly for an even bake and wonderful flavor.
Step 4: Prepare Fried Shallots
Thinly slice 1-2 shallots and heat a small skillet over medium-high heat with enough oil to submerge the shallots. Once hot, carefully add the shallots and fry them for about 3-4 minutes, stirring frequently until they turn golden brown and crispy. Remove them from the pan and drain them on a paper towel-lined plate to absorb excess oil.
Step 5: Bake Casserole
Sprinkle the remaining Parmesan cheese over the green bean mixture in the baking dish, followed by the crispy fried shallots. Bake in your preheated oven for 20-25 minutes, or until the casserole is bubbling and the top has turned a beautiful golden brown. Once out of the oven, let it sit for a few minutes before serving.

Homemade Green Bean Casserole Recipe FAQs
What kind of green beans should I use?
Absolutely use tender, crisp fresh green beans for the best texture in your Homemade Green Bean Casserole. Look for beans that are bright green with a firm snap; avoid any that have dark spots or are shriveled, as they won’t provide the freshness you want in your dish.
How should I store leftovers?
To store leftover casserole, place it in an airtight container and keep it in the refrigerator for up to 3 days. When you’re ready to enjoy it again, reheat in the oven at 350°F until warmed through, or microwave it for a quick option.
Can I freeze my casserole?
Yes, you can freeze the unbaked Homemade Green Bean Casserole for up to 3 months. Make sure to wrap it tightly in aluminum foil or place it in a freezer-safe dish to avoid freezer burn. When you’re ready to bake, simply thaw it overnight in the refrigerator before cooking as directed.
What if my mushroom sauce is too thick?
If your creamy mushroom sauce turns out thicker than you’d like, don’t worry! Simply add a splash of extra cream or plant-based milk while stirring over low heat until you reach your desired consistency. If you’ve added too much liquid, you could also adjust by thickening it with a little more flour mixed into a small amount of cold water, then whisking it into the simmering sauce.
Is this recipe suitable for a vegan diet?
Definitely! To make a vegan version of the Homemade Green Bean Casserole, simply substitute the butter with olive oil, use coconut milk instead of cream, and skip the parmesan cheese or replace it with nutritional yeast for a cheesy flavor without dairy. This way, you can enjoy all the flavors without compromising on dietary choices!
Can pets safely eat this casserole?
While the Homemade Green Bean Casserole contains healthy ingredients, it’s best to keep it away from pets, especially since some elements like onion (in the fried shallots) can be harmful to them. Always stick to pet-safe foods to avoid any health issues, and consult your veterinarian if you’re unsure about a specific ingredient.
