  • Total Time: 45 minutes
  • Yield: 10 servings

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

  1. Preheat Oven: Preheat your oven to 400ºF (204ºC) to prepare for baking the casserole.
  2. 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.
  3. 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.
  4. Simmer Sauce: Bring the sauce to a simmer and cook, stirring frequently, until it thickens—about 5 minutes.
  5. Combine Beans and Sauce: Pour the creamy sauce over the blanched green beans and stir gently to coat all the beans evenly.
  6. Assemble the Casserole: Transfer the green bean mixture into a 9″ x 13″ baking dish. Evenly sprinkle the French fried onions on top.
  7. 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.
  8. 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.
