Instructions

Collect green beans, cream of mushroom soup, and fried onions, making sure everything is prepped and ready for a smooth cooking process.
Trim and blanch green beans in boiling water for 3–4 minutes until tender-crisp, then drain and set aside.
Combine blanched green beans with cream of mushroom soup in a bowl, stirring until evenly coated.
Transfer the mixture to a casserole dish, add extra soup if desired, and top with fried onions for crunch.
Bake at 400°Fahrenheit (200°Celsius) for about 10 minutes until the top is golden and the onions are crisp.

Notes

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.
