How to Make Green Bean Casserole
-
Boil the fresh green beans in salted water for about 3 minutes. Then, drain and immediately cool them under cold water to stop the cooking process. Pat them dry with a towel to ensure they’re not watery.
-
Toss the sliced yellow onions with flour, panko, salt, and pepper until they are evenly coated. Carefully deep-fry them in hot vegetable oil for about 1.5 minutes until they’re lightly golden. Drain the fried onions on paper towels to remove excess oil.
-
Sauté the chopped mushrooms in a skillet with melted butter over medium heat until soft and lightly browned. Add minced garlic for another minute, then sprinkle in flour to thicken the mixture to a creamy base.
-
Stir in the vegetable or chicken broth and cream gradually, allowing the sauce to simmer until it thickens to your desired consistency—this should take about 5-7 minutes.
-
Combine the prepared green beans with the creamy mushroom sauce in a large baking dish, mixing them gently. Top generously with the crispy fried onions for that delightful crunch.
-
Bake in a preheated oven at 350°F (180°C) for about 15 minutes until bubbly and the onions are a deep golden brown. Be sure to check at the 10-minute mark to prevent burning the topping.
Optional: Garnish with fresh herbs for a pop of color and flavor.

Tips for the Best Green Bean Casserole
Fresh Beans Matter: Use fresh green beans for the best flavor and texture; if using frozen, ensure they’re completely thawed and dried to prevent sogginess.
Onion Crunch: Don’t rush the frying of the onions; take your time to achieve a perfect golden color. This step is key for a crunchy topping in your green bean casserole.
Avoid Overcooking: Boil the green beans only for about 3 minutes; they should be vibrant and slightly tender. Overcooking can lead to mushy beans, which ruin the texture.
Thick Sauce Tip: If your sauce isn’t thickening, let it simmer a little longer. The flour needs time to blend well with the liquids, creating that luscious coating for your green beans.
Layering Flavors: Get creative! Feel free to add some grated cheese or herbs to the creamy sauce for extra flavor; this simple adjustment can elevate your green bean casserole to new heights!
With these expert tips, your green bean casserole will be nothing short of spectacular!
