Recipe Info

Ingredients You’ll Need

• 1 pound fresh green beans, trimmed and cut in half
• 2 tablespoons unsalted butter
• 1 medium onion, finely chopped
• 2 garlic cloves, minced
• 8 ounces mushrooms, sliced
• 2 tablespoons all-purpose flour
• 1 cup chicken or vegetable broth
• 1 cup heavy cream (or half-and-half for lighter option)
• 1 teaspoon salt (or to taste)
• ½ teaspoon black pepper
• 1 teaspoon soy sauce (optional, for depth)
• 1 ½ cups crispy fried onions (store-bought or homemade)

Step-By-Step Instructions

1. Blanch the green beans
   Bring a large pot of salted water to a boil. Add green beans and cook for 3–4 minutes until bright green and just tender. Drain and immediately plunge into ice water to stop cooking. Set aside.
2. Make the mushroom sauce
   In a large skillet, melt butter over medium heat. Add onion and garlic, cooking until softened and fragrant. Stir in mushrooms and cook until golden brown, about 5–6 minutes.
3. Thicken the sauce
   Sprinkle flour over the mushrooms, stirring to coat. Slowly whisk in broth, then cream. Bring to a gentle simmer and cook until slightly thickened, about 5 minutes. Season with salt, pepper, and soy sauce if using.
4. Assemble the casserole
   Combine the blanched green beans with the creamy mushroom sauce. Transfer to a greased 9×13-inch baking dish.
5. Top & bake
   Sprinkle crispy fried onions evenly over the top. Bake at 375°F (190°C) for 20–25 minutes, until hot and bubbly with golden onions.

Helpful Notes & Tips

• Don’t overcook the beans: Blanching keeps them bright and crisp-tender.
• Make ahead: Assemble the casserole (without topping) a day in advance. Store covered in the fridge, then add onions and bake before serving.
• For thicker sauce: Simmer an extra 2–3 minutes until desired consistency.

Recipe Variations

• Cheesy twist: Stir in ½ cup grated Gruyère, cheddar, or Parmesan for extra richness.
• Lighter version: Swap heavy cream with evaporated milk or half-and-half.
• Add protein: Fold in shredded rotisserie chicken for a heartier side.

Serving Suggestions

• Serve alongside a roasted turkey, chicken for a holiday spread.
• Pair with mashed potatoes and stuffing for the ultimate comfort plate.
• Add a fresh side salad with vinaigrette to balance the creamy richness.
