Ingredients You’ll Need
The beauty of this dish lies in its simplicity and thoughtfully chosen ingredients. Each one plays a vital role in balancing the flavors, textures, and colors — from the bright green of the beans to the velvety cream sauce and the irresistible crunch of fried onions.
- 2 pounds fresh or frozen green beans: Fresh beans provide a crisp texture, but frozen works beautifully for convenience without sacrificing flavor.
- 2 tablespoons unsalted butter: Adds richness to the creamy sauce and helps develop that silky texture once melted.
- 2 tablespoons all-purpose flour: Essential for thickening the sauce to that perfect creamy consistency.
- 1 teaspoon onion powder: Enhances the onion flavor subtly without overpowering the dish.
- 1 teaspoon garlic powder: Brings mild warmth and depth to complement the other seasonings.
- 1 teaspoon sea salt: Seasons everything evenly and brings out the natural sweetness of the beans.
- ½ teaspoon freshly cracked black pepper: Adds a gentle kick and aromatic freshness.
- ¼ teaspoon ground nutmeg: A secret touch that offers a hint of warmth and complexity to the sauce.
- 1 teaspoon Dijon mustard: Brightens the sauce with subtle tang and balances the creaminess.
- 1 cup vegetable or chicken stock: Provides body and umami depth to the sauce without heaviness.
- 2 cups half and half: Creates the luscious, velvety foundation for the casserole’s creamy sauce.
- 1 ½ cups French fried onions: The crowning glory — these crispy onions add the crunch and caramelized flavor that make this casserole irresistible.
How to Make Green Bean Casserole Recipe with Creamy Sauce and Crispy Fried Onions Recipe
Step 1: Prepare & Blanch the Green Beans
Start by bringing a large pot of salted water to a boil — the salt seasons the beans as they cook, enhancing their natural flavor. Blanch your green beans until they are just tender, about 3 minutes if fresh or 2 minutes if frozen. Then, immediately transfer them to an ice bath. This stops the cooking process and helps keep them vibrant green and crisp-tender, which is crucial because you’ll finish cooking them in the oven later. Drain the beans well and pat dry to prevent excess moisture in the casserole.
Step 2: Craft the Creamy Sauce
While the beans cool, melt the butter in a large saucepan over medium-high heat. Whisk in flour and your seasonings — onion powder, garlic powder, salt, pepper, nutmeg, and the zing of Dijon mustard. This step builds the base flavor and thickens the sauce. Slowly add the vegetable or chicken stock while whisking to keep everything smooth, then pour in the half and half and bring the mixture to a simmer. Stir regularly as the sauce thickens for about five minutes. The result is a rich, velvety sauce that perfectly coats each green bean.
Step 3: Assemble and Bake
Transfer the blanched green beans to a 9×13-inch baking dish and pour the warm creamy sauce over them, tossing gently to coat every bean. Bake in your preheated 375°F oven until the sauce bubbles happily around the edges, roughly 20 minutes. Give the casserole a gentle toss, sprinkle the French fried onions evenly on top, then pop it back in the oven for another 10 minutes so the onions turn irresistibly golden and crunchy. This final bake melds all the flavors together beautifully and delivers that iconic crispy topping everyone loves.
How to Serve Green Bean Casserole Recipe with Creamy Sauce and Crispy Fried Onions Recipe
Garnishes
To add an extra pop of freshness and color, try sprinkling some finely chopped fresh parsley or chives right after baking. The herbs contrast the richness of the creamy sauce and add a lovely brightness. If you’re feeling adventurous, a few toasted sliced almonds can also provide an elegant nutty crunch alongside the crispy fried onions.
Side Dishes
This casserole pairs beautifully with a variety of mains. Traditional roasted turkey or glazed ham are classic companions, especially during festive meals. For a vegetarian spread, try serving it alongside a hearty lentil loaf or herbed quinoa salad. The creamy yet light texture of the casserole makes it a versatile side that complements both meat-based and plant-based dishes beautifully.
Creative Ways to Present
If you’re aiming to impress guests, consider serving this Green Bean Casserole Recipe with Creamy Sauce and Crispy Fried Onions Recipe in individual ramekins for a personal touch. Layer the beans and sauce, then top each with fried onions right before serving, so everyone gets their own golden bubbly portion. Another idea is to sprinkle a bit of extra cheese under the fried onions before baking for a decadent melted topping that’s sure to disappear quickly.
Make Ahead and Storage
Storing Leftovers
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. The flavors will meld even more, though the fried onions might lose a bit of their crunch. You can refresh the crispiness by adding fresh fried onions after reheating.
Freezing
This casserole freezes well if you want to prepare it in advance. Freeze the baked casserole (without the fried onions topping) in a freezer-safe container for up to 2 months. When ready to enjoy, thaw overnight in the fridge and add fresh fried onions on top before baking or reheating.
Reheating
To reheat, place the casserole in an oven-safe dish and warm at 350°F until heated through, about 20 minutes. If the topping has softened, sprinkle more fried onions over the top and broil for a minute or two to revive that crispy finish. Avoid microwaving if possible to keep the texture pleasant and crispy.
FAQs
Can I use canned green beans instead of fresh or frozen?
Fresh or frozen green beans are recommended for their texture and flavor. Canned beans tend to be softer and can become mushy when baked, but if you’re in a pinch, drain and rinse canned beans well, then reduce blanching time to avoid overcooking.
Is there a dairy-free way to make this recipe?
Absolutely! Substitute the butter with a plant-based margarine, and swap the half and half with coconut milk or an unsweetened nut milk. Use vegetable stock to keep it vegetarian and dairy-free while still maintaining creamy texture and great flavor.
Why do you blanch the green beans before baking?
Blanching partially cooks the beans and locks in their vibrant color and crunch. It also ensures they finish cooking evenly in the oven without becoming mushy or lifeless.
Can I prepare the casserole fully assembled ahead of time?
Yes! You can assemble the casserole a day before baking. Just wait to add the fried onions on top until right before baking to keep them crisp and golden.
What can I substitute for French fried onions?
If you can’t find French fried onions, you can make your own by thinly slicing onions, dusting them in flour, and frying until golden, or use crispy shallots or even panko breadcrumbs toasted with butter for a crunchy topping.

Ingredients
Green Beans
- 2 pounds fresh or frozen green beans
Sauce
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- 1 teaspoon sea salt
- ½ teaspoon freshly cracked black pepper
- ¼ teaspoon ground nutmeg
- 1 teaspoon Dijon mustard
- 1 cup vegetable or chicken stock
- 2 cups half and half
Topping
- 1 ½ cups French fried onions
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C) and position a rack in the center of the oven to ensure even baking.
- Blanch the Green Beans: Bring a large pot of salted water to a boil over high heat. Prepare a large bowl with ice water. Add the green beans to the boiling water and cook for about 3 minutes if fresh, or 2 minutes if frozen, until just tender. Drain and immediately immerse in the ice water bath for 2 minutes to stop cooking. Drain again and pat dry thoroughly.
- Arrange Green Beans: Place the blanched and dried green beans into a 9×13-inch baking dish, spreading them out evenly.
- Make the Cream Sauce: In a large saucepan over medium-high heat, melt the butter. Whisk in the flour, onion powder, garlic powder, salt, pepper, nutmeg, and Dijon mustard. Cook for about 2 minutes until the mixture is fragrant and forms a roux.
- Add Liquids: Slowly whisk in the vegetable or chicken stock, making sure the mixture is smooth. Slowly add the half and half, continuing to whisk to combine. Bring the sauce to a simmer over medium heat and cook, stirring occasionally, until the sauce has thickened, about 5 minutes.
- Combine Sauce and Beans: Pour the creamy sauce over the green beans in the baking dish and toss gently to coat all the beans evenly.
- Bake the Casserole: Place the baking dish in the preheated oven and bake until the sauce bubbles, approximately 20 minutes. Remove from the oven, toss the green beans gently to mix, then sprinkle the French fried onions evenly on top.
- Final Bake: Return the casserole to the oven and bake for an additional 10 minutes, or until the onions are golden brown and crisp.
Notes
- Use either fresh or frozen green beans depending on availability; blanching before baking ensures even cooking.
- For a vegetarian version, use vegetable stock instead of chicken stock.
- You can prepare the sauce a day ahead and refrigerate it for convenience.
- Make sure to pat the green beans dry after blanching to avoid a watery casserole.
- French fried onions can be found in most grocery stores or homemade for extra crispness.
