Ingredients
Scale
- 1 lb fresh green beans, rinsed, trimmed and halved (454 g)
- 12 oz mushrooms, trimmed and cut into ½-inch pieces (340 g)
- 2 medium onions, thinly sliced
- 2 cloves garlic, minced
- 1 cup chicken broth (240 ml)
- 1 cup half-and-half (240 ml)
- ¼ cup all-purpose flour (30 g)
- 2 tbsps all-purpose flour (15 g)
- 2 tbsps unsalted butter
- 2 tbsps panko bread crumbs
- 2 ½ tbsps kosher salt, divided
- ½ tsp freshly ground black pepper
- ¼ tsp freshly ground nutmeg
- Nonstick cooking spray
Instructions
- Onion Preparation: Combine finely chopped onions, all-purpose flour, panko breadcrumbs, and kosher salt in a mixing bowl, ensuring even coating.
- Roasting Onions: Spread seasoned onion mixture on a parchment-lined sheet pan, roasting at 475°F for 30 minutes with a mid-point stir to achieve golden crispiness.
- Green Bean Blanching: Boil salted water and submerge green beans for precisely 5 minutes, then immediately transfer to ice water to preserve color and texture.
- Mushroom Sauce Base: Sauté sliced mushrooms and minced garlic in a skillet until golden, then incorporate nutmeg and flour to create a rich roux.
- Sauce Development: Slowly whisk vegetable broth and half-and-half into the mushroom mixture, creating a smooth, velvety sauce.
- Casserole Assembly: Fold blanched green beans into the creamy mushroom sauce, transfer to a baking dish, and generously top with roasted crispy onions.
- Final Baking: Reduce oven temperature to 400°F and bake for 15 minutes until heated through and onions reach maximum crispness.
- Serving: Allow casserole to rest for 5 minutes before serving to enhance flavor melding and sauce consistency.
Notes
- Blanch with Precision: Exactly 5 minutes of boiling ensures green beans remain vibrant and crisp without becoming mushy.
- Roast Onions Strategically: Spread onion mixture in a single layer and stir midway to achieve golden, even crispiness.
- Create Smooth Sauce: Whisk broth and half-and-half gradually to prevent lumps and develop a silky, rich base.
- Rest and Settle: Allow casserole to rest 5 minutes after baking so sauce thickens and flavors fully develop.
