Ingredients
Green Beans
- 36 ounces (1020g) fresh green beans, rinsed, trimmed, and cut into 1-2″ pieces
Sauce
- 3 Tablespoons (42g) unsalted butter
- 2 cloves garlic, minced
- 3 Tablespoons (23g) all-purpose flour
- ¾ cup (180mL) chicken or vegetable broth
- ¾ cup (180mL) heavy cream
- 1 teaspoon salt
- ½ teaspoon black pepper
Topping
- 6 ounces (170g) French fried onions
Instructions
- Preheat Oven: Preheat your oven to 400ºF (204ºC) to prepare for baking the casserole.
- Blanch the Green Beans: In a large pot, bring about 1 gallon (128 oz) of salted water to a boil (use about 1½ tablespoons salt). Add the fresh green beans and boil for 5 minutes. Prepare a large bowl of ice water. Drain the beans quickly in a colander and immediately submerge them in the ice water to stop cooking and keep them crisp. Chill for a few minutes, then drain and place into a large bowl.
- Make the Roux and Sauce: In a large skillet over medium to medium-high heat, melt the butter. Add the minced garlic and cook for about 3 minutes until softened, reducing heat if garlic begins to brown. Add salt and pepper and cook for another minute. Sprinkle the flour over the mixture and stir well to form a roux. Cook the roux for 2 minutes, then gradually whisk in the broth, ensuring no lumps. Once smooth, slowly whisk in the heavy cream.
- Simmer Sauce: Bring the sauce to a simmer and cook, stirring frequently, until it thickens—about 5 minutes.
- Combine Beans and Sauce: Pour the creamy sauce over the blanched green beans and stir gently to coat all the beans evenly.
- Assemble the Casserole: Transfer the green bean mixture into a 9″ x 13″ baking dish. Evenly sprinkle the French fried onions on top.
- Bake: Bake in the preheated oven for 23-25 minutes until hot and bubbly. If the onions brown too quickly, loosely cover the dish with foil starting around 15 minutes. Remove from oven and serve immediately.
- Storage: Store any leftovers in an airtight container in the refrigerator for up to 5 days.
Notes
- Blanching the green beans ensures they stay crisp and retain vibrant color.
- If you prefer a vegetarian version, use vegetable broth instead of chicken broth.
- Cover the casserole with foil if the topping browns too fast during baking.
- Use fresh green beans for the best texture and flavor over canned or frozen.
- French fried onions add the classic crunch topping without using canned soup.
