Step-by-Step Procedure to Make a Perfect Green Bean Casserole with Cream of Mushroom Soup
First: Gather Ingredients for the Casserole
Collect all the ingredients you’ll need for the casserole, including green beans, cream of mushroom soup, and fried onions. Make sure everything is ready to go, so the cooking process is smooth and easy. Having everything prepped ensures a stress-free time in the kitchen.

Second: Blanch the Green Beans
Trim the ends of the green beans and blanch them in a large skillet of boiling water for about 3-4 minutes. Once they are tender but still crisp, drain the beans and set them aside in a bowl. This step ensures the beans will be perfectly cooked in the casserole.

Third: Make the Green Bean Mixture
In a bowl, pour the cream of mushroom soup over the blanched green beans. Mix until the beans are completely coated in the mushroom sauce. This creamy mixture forms the base of the casserole.

Fourth: Assemble the Casserole
Transfer the green bean and mushroom mixture into a casserole dish. You can add a little more soup or sauce if you’d like it extra creamy. Once everything is in the dish, sprinkle fried onions on top for a crunchy finish.

Five: Bake the Casserole
Place the casserole in the oven and bake at 400°Fahrenheit (200°Celsius) for 10 minutes. Bake until the top is golden brown and the onions are crispy. This will give the casserole a delicious, crunchy topping and a warm, creamy interior.

Handy Tips for Tasty Wins:
- Prep and Store: If you’re making it ahead, assemble the casserole, but leave the crispy topping off. Cover it and refrigerate for up to 2 days, then add the topping just before baking for that perfect crunch.
- Boost the Creaminess: Mix in a bit of sour cream or cream cheese with the mushroom soup for a richer texture. It adds a subtle tang and creaminess that elevates the dish.
- Try a Veggie Swap: Switch out the green beans for other veggies like Brussels sprouts or peas for a fresh twist while keeping the dish comforting.
- Keep the Toppings Fresh: To keep the fried onions extra crispy, toast them separately in the oven and sprinkle on top right before serving, preserving their crunch and golden color.
