This easy green bean casserole is the retro recipe you likely remember from childhood. Classic green bean casserole features a creamy mushroom sauce, tender green beans and crispy fried onions on top.
Preheat the oven to 375°F. Spray a 3-quart casserole dish with nonstick spray, and set aside.
In a large bowl, mix together the cream of mushroom soup, milk, and pepper. Then stir in the drained green beans and 0.5 cup of the crispy fried onions.
Pour the mixture into the prepared casserole dish, and spread it out to an even layer. Top the casserole with the remaining fried onions.
Bake the casserole for 20 minutes, or until bubbly and the onions are a dark golden color.
Let casserole rest for 5 minutes before serving.
Notes
For extra flavor and texture, consider adding chopped canned water chestnuts or chopped fresh yellow onion to the mixture before baking.
