Chicken and Broccoli Casserole Recipe
Total time: 35 minutes
Cook broccoli in boiling salted water until it turns bright green, about 3 minutes. Drain and plunge broccoli into bowl of ice water until cold. Drain and set aside.
Preheat broiler. Season chicken with 1 tsp. salt and 1/4 tsp. black pepper. In a large nonstick skillet, heat 1/2 Tbsp. oil over medium-high heat. Add chicken and cook, turning occasionally, until golden on all sides, about 8 minutes. Transfer to a bowl.
Add to pan 1/2 Tbsp. oil and mushrooms. Sauté mushrooms until golden, about 4 minutes. Add onion, garlic and thyme and sauté until onion begins to soften, about 3 minutes. Add wine and simmer until it evaporates, about 30 seconds. Sprinkle flour over mixture and stir to blend. Stir in milk and cream and bring to a boil; then reduce the heat and simmer, stirring, until sauce thickens slightly, about 3 minutes. Stir in blanched broccoli and reserved chicken, and cook until warmed through, about 3 minutes. Season to taste with salt and pepper. Transfer mixture to a 9-inch, square baking dish or gratin dish.
In a medium bowl, mix Parmesan, panko and remaining 1 Tbsp. oil, tossing well. Sprinkle mixture over top of casserole. Broil, watching closely, for 2 to 3 minutes, or until bread crumb mixture is golden brown.
