Step-by-Step Cooking Instructions

Let’s get started with this easy Thanksgiving green bean casserole. Follow these step-by-step instructions for a perfect side dish:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Green Beans: If using fresh green beans, bring a large pot of salted water to a boil. Add the trimmed green beans and cook for 5-7 minutes, until tender but still crisp. Drain and set aside. If using frozen or canned green beans, ensure they are thawed and well-drained before proceeding.
3. Mix the Sauce: In a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, and ground black pepper. Stir until the sauce is smooth and well combined.
4. Assemble the Casserole: Add the green beans to the sauce mixture and stir until they are evenly coated. Stir in ½ cup of crispy fried onions into the mixture for added crunch throughout the casserole.
5. Bake the Casserole: Transfer the green bean mixture to a greased 9x13-inch baking dish and spread it out evenly. Bake uncovered in the preheated oven for 25 minutes.
6. Add the Topping: After 25 minutes, remove the casserole from the oven. Sprinkle the remaining 1 cup of crispy fried onions on top.
7. Bake Again: Return the casserole to the oven and bake for an additional 5-10 minutes, or until the onions on top are golden brown and crispy.
8. Serve: Once the casserole is golden and bubbly, remove it from the oven and let it cool for a few minutes before serving.

How to Cook Easy Green Bean Casserole: A Step-by-Step Guide

Step 1: Prepping the Green Beans
If you’re using fresh green beans, blanch them first. This quick boil softens the beans while keeping them bright green and slightly crisp. Be sure to drain them well to avoid adding extra water to the casserole. For canned or frozen green beans, make sure to drain or thaw them properly.

Step 2: Mixing the Sauce
The cream of mushroom soup is the base of the casserole’s sauce. Add milk to thin it out, making the sauce creamy but not too thick. The soy sauce is a secret ingredient that adds depth and richness to the dish. Don’t skip it—it enhances the umami flavor of the mushrooms and ties the whole casserole together.

Step 3: Baking the Casserole
Baking the casserole in two stages allows the green beans to soak up the creamy sauce while ensuring that the fried onion topping stays crispy. First, bake the casserole without the onions so the dish becomes hot and bubbly. Then, add the onions in the last 10 minutes to keep them from burning.

Common Mistakes to Avoid

To make sure your Thanksgiving green bean casserole turns out perfectly, avoid these common mistakes:

1. Overcooking the Green Beans: Whether using fresh or frozen green beans, make sure they are cooked until tender but still crisp. Overcooked beans will become mushy when baked.
2. Adding the Onions Too Early: The crispy onions can burn if baked for too long, so make sure to add them only in the last 10 minutes of baking.
3. Not Draining the Green Beans: If using canned or frozen green beans, be sure to drain them thoroughly to prevent a watery casserole.
4. Not Seasoning the Sauce: Although the cream of mushroom soup is seasoned, a bit of extra salt, pepper, and soy sauce can elevate the flavor. Taste the sauce before baking to adjust seasoning if needed.
