Classic Homemade Green Bean Casserole: Best Easy Side Dish

Classic Homemade Green Bean Casserole - featured image

A refined, homemade green bean casserole featuring fresh blanched beans, a rich mushroom cream sauce, and a crunchy topping of fried onions and panko. This recipe avoids the sogginess of traditional versions for a perfect texture.

Ingredients

Scale
  • 1.5 lbs fresh green beans, trimmed and cut into 1-inch pieces
  • 2 tablespoons unsalted butter (for sautéing)
  • 2 medium shallots, finely minced
  • 8 oz cremini mushrooms, sliced
  • 2 cloves garlic, minced
  • 1/2 cup heavy cream
  • 1/2 cup low-sodium chicken stock
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon salt (plus more to taste)
  • Black pepper to taste
  • 1.5 cups French fried onions
  • 1/4 cup panko breadcrumbs
  • 2 tablespoons grated Parmesan cheese
  • 1 tablespoon melted butter (for topping)

Instructions

  1. Bring a large pot of salted water to a boil. Blanch green beans for 3-4 minutes until tender-crisp, then drain and plunge into an ice bath to stop cooking. Pat dry.
  2. In a large skillet or Dutch oven, melt 2 tablespoons of butter over medium heat. Add shallots and mushrooms, cooking for 5-7 minutes until mushrooms are golden brown and shallots are soft.
  3. Stir in minced garlic and cook for 30 seconds until fragrant. Pour in heavy cream and chicken stock, bringing to a gentle simmer.
  4. Whisk in Dijon mustard, salt, and black pepper. Simmer for 2 minutes until the sauce slightly thickens.
  5. Add the blanched green beans to the skillet and stir gently to coat evenly in the sauce. Remove from heat.
  6. Pour the bean and sauce mixture into a 9×13 inch baking dish and spread evenly.
  7. In a small bowl, mix French fried onions, panko breadcrumbs, Parmesan cheese, and melted butter until coated.
  8. Preheat oven to 375°F (190°C). Sprinkle the topping evenly over the casserole.
  9. Bake for 15-20 minutes until the topping is golden brown and the sauce is bubbling.
  10. Remove from oven and let rest for 5 minutes before serving.

Notes

Do not skip the ice bath when blanching beans to maintain texture and color. Ensure mushrooms are browned well to build flavor. If making ahead, assemble but do not bake until ready to serve to prevent soggy topping. For a vegetarian version, substitute chicken stock with vegetable stock.
