Step‑by‑Step Instructions for Homemade Green Bean Casserole
Step 1: Prepare the Fried Shallots
Begin by slicing the shallots thinly, then heat about 1 cup of oil in a frying pan over medium heat. Once the oil is hot, carefully add the sliced shallots, cooking them until they are golden brown and crispy—this should take about 6–8 minutes. Remove the fried shallots from the pan and drain them on paper towels; set aside to cool.
Step 2: Blanch the Green Beans
Bring a large pot of salted water to a boil while you prepare the green beans, trimming the ends off if needed. Once boiling, carefully add the green beans and blanch them for 2–3 minutes until they are bright green and slightly tender. Immediately transfer the beans to a bowl of ice water to halt the cooking process, preserving their crispness and color.
Step 3: Make the Mushroom Sauce
In the same skillet used for the shallots, melt 4 tablespoons of butter over medium heat. Add sliced mushrooms and sauté them for about 5–7 minutes until they are beautifully golden and tender. Stir in minced garlic and cook for an additional minute, then pour in 1 cup of heavy cream, along with garlic powder, salt, and pepper, letting it simmer for 4–5 minutes until slightly thickened for your creamy mushroom sauce.
Step 4: Combine Ingredients
Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the blanched green beans with the rich mushroom sauce, mixing them gently until all the beans are evenly coated. Pour half of the fried shallots into the bowl and mix again, ensuring that each bite of this homemade green bean casserole has that crunchy touch.
Step 5: Top and Bake
Transfer the mixture into a greased baking dish, spreading it evenly. Sprinkle the remaining fried shallots and a generous amount of grated parmesan on top for added flavor and crunch. Bake in your preheated oven for 27–40 minutes; you’ll know it’s done when the casserole is bubbling around the edges, and the top is golden and crispy.

How to Store and Freeze Homemade Green Bean Casserole
Fridge: Store any leftovers of your homemade green bean casserole in an airtight container in the refrigerator for up to 3 days. This keeps the flavors fresh while maintaining the casserole’s creamy texture.
Freezer: If you have extra casserole or plan to make it ahead, tightly wrap it in plastic wrap and then aluminum foil before freezing for up to 3 months. For best results, bake from frozen for 45–60 minutes.
Reheating: To enjoy leftovers, simply reheat in a preheated oven at 350°F (175°C) for 20–25 minutes, or until heated through. You can add a sprinkle of fresh fried shallots on top for extra crunch!
Make-Ahead: Assemble the casserole without baking, cover well, and refrigerate for up to 2 days before your event. This means you can have your delicious homemade green bean casserole ready to pop in the oven when it’s go-time!
