Green Bean Casserole Recipe
Introduction
Green Bean Casserole is a classic comfort food that’s perfect for holidays or any family dinner. This creamy, savory dish combines tender green beans with a rich mushroom sauce and crispy fried onions for a satisfying texture contrast.

Ingredients
- 2 (14.5 ounce) cans cut green beans, drained well
- 10.75 ounce cream of mushroom soup
- ½ cup whole milk
- ½ teaspoon Worcestershire sauce
- ¼ teaspoon garlic powder
- ¼ teaspoon salt
- ½ teaspoon black pepper
- 6 ounces crispy fried onions, divided
Instructions
- Step 1: Preheat the oven to 350°F. Lightly coat a medium baking dish (1.5 to 2 quarts) with nonstick cooking spray and set aside.
- Step 2: In a large mixing bowl, stir together the cream of mushroom soup, milk, Worcestershire sauce, garlic powder, salt, and black pepper until well combined.
- Step 3: Add the drained green beans and half of the crispy fried onions to the mixture. Stir gently to combine.
- Step 4: Transfer the green bean mixture to the prepared baking dish. Bake uncovered for 25 to 30 minutes, or until the center is bubbly.
- Step 5: Remove the casserole from the oven, sprinkle the remaining crispy fried onions on top, and bake for an additional 5 to 10 minutes until the onions are golden brown.
- Step 6: Let the casserole rest for 5 minutes before serving.
Tips & Variations
- Use fresh or frozen green beans instead of canned for a fresher flavor; simply blanch them before mixing.
- Try substituting cream of mushroom soup with cream of celery or cream of chicken for a different taste.
- Add a handful of shredded cheddar cheese on top before baking for extra richness.
- For a gluten-free option, use gluten-free fried onions or make your own crispy topping with crushed gluten-free crackers.
Storage
Store leftover green bean casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 325°F until warmed through to maintain its crispy topping, or use a microwave for quicker reheating but expect softer onions.
