Ingredients for Green Bean Casserole
- Green beansโI prefer regular green beans over French cut or haricot verts in this recipe because regular beans stand up best in the sauce with a crisp-tender bite. Thawed frozen green beans or blanched fresh green beans work best.
- ButterโButter creates a rich base for sautรฉing and adds a velvety flavor to the sauce.
- OnionโSautรฉed onions bring sweetness and depth to the sauce, perfectly balancing the creamy elements.
- Garlic clovesโ Garlic gives the sauce a savory warmth and aromatic quality, deepening the overall flavor.
- Kosher salt and freshly ground black pepperโThese essentials enhance the ingredient’s natural flavors and add a touch of seasoning to keep the dish balanced.
- All-purpose flourโFlour thickens the sauce, creating a perfect texture that clings to each green bean.
- Chicken brothโChicken broth provides a savory, umami base that prevents the sauce from feeling too heavy, adding depth to every bite.
- Cream or half-and-halfโEither dairy option adds richness and a lush mouthfeel, making the casserole creamy without being overly thick or gloopy.
- Dried thymeโThymeโs earthy, subtle herb flavor adds a hint of holiday warmth.
- Soy sauceโJust a splash of soy sauce enhances the umami in the dish, balancing the cream with a slightly salty note and adding depth to the sauce.
- French-fried onionsโThese crispy, savory onions bring that classic crunch on top that is everyone’s favorite part.

Why Frozen or Fresh Green Beans Work Best
Which is better, frozen or canned green beans for green bean casserole? While the original green bean casserole recipe often relies on canned green beans, fresh or frozen green beans elevate the dish, keeping the beans tender with a slight crunch rather than mushy. Regular green beans stand up well to the rich, creamy sauce, giving each bite texture and flavor. If using fresh beans, blanch them first to keep their color vibrant and their texture spot-on; if using frozen, thaw them before adding to the casserole.
How to Make Green Bean Casserole
- Thaw frozen green beans or blanche fresh green beans. I prefer the ease of using frozen green beans but if you use fresh, give them a quick cook before mixing. Blanching green beans in salted boiling water for about 5 minutes is a quick way to soften them while retaining their vibrant color and snappy bite. Salted water infuses flavor into the gently cooked beans.
- Prepare the white sauce. Cook the onion and garlic until soft then sprinkle with the flour. Cook the flour for a minute to lose its raw taste, stirring as it cooks so it doesn’t burn.
- Add the chicken broth, cream or half-and-half, thyme, and soy sauce and cook to reduce and thicken. Chicken broth adds flavor and acts as a thickener with the flour. Cream or half-and-half adds more thickening power to the sauce with thyme adding an herbal note and soy sauce brings umami, salt, and depth.
- Fold the blanched green beans into the sauce. Cook for a few minutes to warm through and start to tenderize the green beans.
- Add the warm green bean mixture to a baking dish, top with the crispy onions, and bake until bubbly. Bake in a 375ยฐF oven for about 30 minutes or until bubbly.
Recipe Tips and Substitutions
- Use frozen green beans instead of fresh green beans. Frozen green beans retain all of the vitamins and minerals of fresh because they’re flash-frozen right after harvest. Three 12-ounce bags of frozen cut green beans make 2 pounds, or 6 cups fresh.
- Add fresh mushrooms to the gravy sauce. Add 8 ounces of sliced cremini or brown mushrooms when sautรฉeing the onions. They add a delicious flavor to the sauce and overall dish.
- Instead of soy sauce, try tamari. Both add an umami depth.
- I like regular green beans instead of haricot verts in this casserole. I’ve found thinner green beans don’t hold up as well in this recipe, nor do canned French-style green beans which can turn to mush.
How to Make Green Bean Casserole Ahead of Time
Preparing green bean casserole ahead of time is a smart way to simplify your Thanksgiving cooking.
- Prepare the beans and sauce then add to the baking dish.
- Wait to add the fried onions until just before baking so they stay crisp and don’t turn soggy.
- Cover the dish with foil and refrigerate for up to 2 days.
- Remove the casserole from the fridge, top with the fried onions, and let it sit at room temperature for about 15-20 minutes before baking.
Storage Tips
To store, cover tightly with foil or transfer leftovers to an airtight container. This casserole will keep well in the fridge for up to three days. To reheat, cover with foil and warm in the oven at 350ยฐF until heated through.
