Ingredients

2 (14.5-ounce) cans cut green beans drained (you can also use 1.5 lbs fresh green beans, trimmed and blanched)
½ cup milk whole milk or 2% works best for richness
1 (10.75-ounce) can condensed cream of mushroom soup choose a good quality brand for the best flavor
1 cup shredded cheddar cheese or your favorite cheese that melts well, like Gruyere or Monterey Jack
1 teaspoon onion powder adds a subtle, savory depth
½ teaspoon black pepper freshly ground is always best
1 (6-ounce) can crispy fried onions these are crucial for that signature crunch and flavor!
2 tablespoons unsalted butter melted (for the topping, optional but recommended for extra golden crispness)

Equipment

Large mixing bowl
1 ½-quart baking dish
Spoon or spatula

Method

Preheat and Prepare: Begin by preheating your oven to 375°F (190°C). Lightly grease a 1 ½-quart baking dish with non-stick cooking spray or a little butter. This ensures easy cleanup and prevents sticking.
Combine the Base: In a large mixing bowl, combine the drained green beans, milk, condensed cream of mushroom soup, shredded cheddar cheese, onion powder, and black pepper. Stir gently with a spoon or spatula until all ingredients are thoroughly mixed and the green beans are evenly coated.

Transfer to Baking Dish: Pour the green bean mixture into your prepared baking dish. Spread it out evenly using the back of your spoon or spatula.
Initial Bake: Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the casserole is bubbly around the edges and the cheese within is melted and gooey.
Add Crispy Topping: Remove the casserole from the oven. Sprinkle the crispy fried onions evenly over the top of the hot casserole. If you desire an extra golden and buttery crunch, drizzle the melted butter over the fried onions.

Final Bake: Return the casserole to the oven and bake for an additional 5-7 minutes, or until the fried onions are golden brown and perfectly crispy. Keep a close eye on them to prevent burning as they can brown quickly.
Serve and Enjoy: Carefully remove the Classic Homemade Green Bean Casserole from the oven. Let it stand for a few minutes before serving to allow it to set slightly. Serve warm and savor every comforting bite!

Notes

To ensure your Classic Homemade Green Bean Casserole turns out perfectly every time, keep these tips in mind:

**Fresh vs. Canned Green Beans:** While canned green beans are traditional and convenient, fresh blanched green beans (boiled for 3-5 minutes until tender-crisp, then shocked in ice water) offer a firmer texture and brighter flavor. If using fresh, ensure they are thoroughly drained to prevent a watery casserole.
**Flavor Boosters:** Don't be afraid to enhance the flavor beyond the basics! A pinch of garlic powder, a dash of Worcestershire sauce, or even a tablespoon of dry sherry can add remarkable depth to the soup mixture. Sautéed fresh mushrooms or a few slivered almonds can also be stirred in or sprinkled on top for extra texture.
**Cheese Choice:** While cheddar is a great choice, experiment with other cheeses like Gruyere for a more sophisticated, nutty flavor, or a blend of Monterey Jack and Colby for extra meltiness. Ensure the cheese is freshly shredded for the best melt – pre-shredded cheeses often contain anti-caking agents that can hinder smooth melting.
**Crispy Onion Strategy:** The fried onions are key! If you want them extra crispy and don't mind extra fat, lightly toss them with a tablespoon of melted butter before sprinkling them on top. For an even crunchier crust, you can also mix a small amount (about ¼ cup) of the fried onions into the green bean mixture before baking, saving the majority for the topping.
**Avoid Overbaking:** Watch the casserole carefully, especially during the second bake with the fried onions. Overbaking can dry out the green beans and cause the onions to burn. Once the onions are golden brown and the casserole is bubbly, it’s ready!
**Customizing the Creaminess:** If you prefer a thicker casserole, reduce the milk to ¼ cup. For a looser, creamier consistency, you can add an extra splash of milk (up to ¼ cup) until it reaches your desired texture.
**Make Ahead Option:** You can assemble the casserole (without the fried onion topping) up to one day in advance. Cover it tightly and refrigerate. When ready to bake, let it sit at room temperature for 20-30 minutes before baking as directed, adding a few extra minutes to the initial bake time if still very cold. Add the fried onions only for the final bake.
