The Green Bean Casserole was first created in 1955 by Dorcas Reilly, a home economist working for the Campbell Soup Company.

Over the years, this simple casserole became synonymous with Thanksgiving and Christmas dinners. Today, it continues to evolve, with countless variations using fresh ingredients, homemade sauces, and gourmet touches.

3. Ingredients for the Classic Green Bean Casserole
Here’s what you’ll need to prepare a traditional version of this dish:
- Green Beans: Fresh or frozen (trimmed and blanched).
- Cream of Mushroom Soup: The classic base for the sauce; can be homemade or canned.
- Milk or Cream: For thinning and enriching the sauce.
- Soy Sauce: Adds umami and depth of flavor.
- Black Pepper: For seasoning.
- Crispy Fried Onions: The iconic topping that gives the casserole its crunch and flavor.
- Optional: Garlic, grated cheese (Parmesan or cheddar), or sautéed mushrooms for extra richness.
4. Step-by-Step Instructions
1: Prepare the Green Beans
- If using fresh green beans: Trim the ends, cut them in half, and blanch in boiling salted water for about 5 minutes. Drain and cool them in ice water to retain their bright green color.
- If using frozen beans: Simply thaw them before mixing.
2: Make the Sauce
- In a saucepan, combine the cream of mushroom soup, milk, soy sauce, and black pepper.
- Heat gently until smooth and warm.
- (Optional) Add sautéed mushrooms or garlic for a homemade touch.
3: Combine
- In a large mixing bowl, combine the green beans and half of the fried onions with the sauce. Stir well to coat everything evenly.
4: Bake
- Transfer the mixture to a greased casserole dish.
- Bake uncovered at 350°F (175°C) for about 25 minutes, until bubbly and hot.
5: Add the Final Crunch
- Sprinkle the remaining fried onions on top.
- Bake for an additional 5–10 minutes, until golden and crisp.
5. Tips for the Perfect Green Bean Casserole
- Don’t overcook the beans: Blanching them briefly ensures they stay tender yet crisp.
- Homemade fried onions: For a fresher taste, coat thinly sliced onions in flour and fry them yourself.
- Use fresh mushrooms: Sautéed mushrooms elevate the flavor and texture of the dish.
- Add cheese: A sprinkle of Parmesan or cheddar creates a rich, savory depth.
- Make ahead: Assemble the casserole (without the topping) a day before baking, then refrigerate until ready to cook.
6. Healthy and Modern Variations
The traditional version is comforting and nostalgic, but there are plenty of ways to make it healthier or more modern:
a. Healthy Green Bean Casserole

8. How to Store and Reheat
- Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
- Freezer: Freeze before baking for up to 3 months. Defrost in the fridge overnight and bake as usual.
- Reheat: Warm in the oven at 350°F until hot. For crispier onions, add a fresh layer before reheating.
9. Common Mistakes to Avoid
- Overcooking the beans: They’ll turn mushy instead of tender.
- Not draining beans properly: Excess water makes the sauce runny.
- Adding onions too early: They’ll lose their crunch.
- Skipping the seasoning: A touch of salt, pepper, and soy sauce balances the flavors.
10. Make-Ahead Holiday Strategy
When cooking for a crowd, time management is key. Here’s how to make this dish ahead without losing quality:
- Prepare the sauce and green beans the day before.
- Store separately or mixed in a covered dish.
- Add the fried onions just before baking to preserve their crunch.
- Bake while your turkey rests—perfect timing!
