Step-by-Step Cooking Instructions

Follow these easy steps to make the best Green Bean Casserole for your next gathering!
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter or cooking spray to prevent sticking.
Step 2: Prepare the Green Beans
If using canned green beans, drain them well. If you’re using fresh green beans, blanch them in boiling salted water for 4-5 minutes, then drain and set aside.
Step 3: Make the Creamy Sauce
In a medium bowl, combine the cream of mushroom soup, milk, soy sauce (if using), garlic powder, salt, and pepper. Stir until well combined. For a cheesy variation, stir in ½ to 1 cup of shredded cheddar cheese.
Step 4: Combine the Ingredients
Add the drained green beans to the soup mixture and stir until the beans are evenly coated. Pour the mixture into the greased baking dish.
Step 5: Add the Fried Onions
Sprinkle ⅔ cup of the fried onions evenly over the top of the casserole.
Step 6: Bake the Casserole
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the sauce is bubbling and the onions on top are golden brown.
Step 7: Add More Crispy Onions
After baking, remove the casserole from the oven and top it with the remaining fried onions. Return it to the oven for another 5 minutes, or until the onions are crispy and browned.
Step 8: Serve and Enjoy!
Once the casserole is golden and bubbly, remove it from the oven. Let it cool for a few minutes before serving. Your Green Bean Casserole is ready to be enjoyed!

Common Mistakes to Avoid
- Overcooking the green beans: If you’re using fresh or frozen green beans, make sure not to overcook them during blanching. You want them tender but still firm.
- Not draining canned beans: Failing to drain the canned green beans can make the casserole watery, so be sure to drain them well.
- Burning the fried onions: Keep an eye on the casserole in the last few minutes to ensure the onions don’t burn. If they start to brown too quickly, cover the dish loosely with aluminum foil.
