For the Green Beans

1/4 teaspoon red pepper flakes (optional) Add this for a gentle heat that enhances the flavor profile of your sautéed green beans.

For the Onions
5 large onions Thinly sliced to yield a sweet, caramelized crunch that elevates the dish.
3 cloves garlic Minced for a fragrant punch that marries beautifully with the onions.

For Cooking
2 tablespoons unsalted butter (divided) Use this to achieve a rich, savory depth in your sauté; feel free to replace with olive oil for a dairy-free option.
1/4 cup chicken broth Adds moisture and flavor; vegetable broth is a great substitute for a vegetarian option.

How to Make Sautéed Green Beans with French Onions

1. Boil a large pot of water and add the fresh green beans. Cook them for just one minute to keep their vibrant color and crunch. Immediately plunge them into a bowl of ice-cold water to stop the cooking process, then drain and set aside.

2. Melt 1 tablespoon of butter in a large skillet over medium-high heat. Toss in the sliced onions, seasoning them with salt and pepper. Cook them for 5-8 minutes until they re soft, then reduce the heat to medium and continue cooking, stirring occasionally, until they re caramelized about 15 minutes. If your pan gets too dry, pour in 1/4 cup of chicken broth to deglaze and keep stirring until the onions are beautifully browned. Finally, add the minced garlic and cook for about 1 minute until fragrant, then turn off the heat and set aside.

3. Wipe out any excess fat from the skillet once it s cool enough. Return the skillet to medium heat and add the remaining tablespoon of butter. When it s hot, toss in the blanched green beans, along with red pepper flakes and a pinch of salt and pepper. Cook while stirring occasionally until heated through, about 1-2 minutes. Top with the caramelized onions and serve these sautéed green beans immediately for maximum enjoyment.

Optional: Garnish with toasted almonds for an extra crunch.
