How to Make Green Bean Casserole with Crispy Onions
-
Preheat your oven to 375°F (190°C). This ensures your casserole cooks evenly and reaches that perfect bubbly goodness.
-
Boil a pot of salted water, then prepare an ice bath in a large bowl. This will help shock the green beans and keep their vibrant color.
-
Cook the green beans in the boiling water for about 2 minutes, just until they’re nearly tender. Immediately transfer them to the ice bath to halt the cooking process.
-
Drain the green beans well and pat them dry. Place them into a baking dish, setting the stage for your creamy sauce.
-
Melt the butter in a saucepan over medium heat. Whisk in the flour, garlic powder, salt, nutmeg, and mustard, cooking for about 2 minutes until bubbly and fragrant.
-
Gradually whisk in the vegetable stock, followed by the heavy cream. Continue stirring for about 5 minutes until the sauce thickens to a silky texture.
-
Pour the creamy sauce over the cooked green beans, ensuring they’re evenly coated for that rich, delicious flavor.
-
Bake uncovered in the oven for 12-15 minutes, or until the sauce is bubbly. Give it a gentle toss during baking for even distribution of flavors.
-
Top the casserole with crispy fried onions, then return it to the oven and bake for an additional 5 minutes, until the onions are a beautiful golden brown.
Optional: Serve with a sprinkle of fresh parsley for a pop of color.

What if my sauce is too thick?
No worries! If your sauce thickens too much while cooking, simply add a splash of vegetable stock or heavy cream to loosen it. Stir continuously until you reach your desired consistency. Keeping an eye on it while whisking is key to a silky sauce!
Are there any dietary considerations I should keep in mind?
Yes! For a gluten-free version, you can easily substitute all-purpose flour with a gluten-free flour blend.
