Step‑by‑Step Instructions for Turkey Broccoli Casserole
Step 1: Preheat and Prepare the Dish
Begin by preheating your oven to 395°F (200°C). While the oven heats, grease a 9×13-inch baking dish with a bit of olive oil or cooking spray to prevent sticking. This will ensure that your Turkey Broccoli Casserole comes out perfectly golden-brown and easy to serve.
Step 2: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add chopped mushrooms and frozen broccoli florets, sautéing for about 5 minutes until the broccoli is heated through and bright green. Stir in minced garlic and continue to cook for an additional minute, allowing the garlic to release its fragrant aroma.
Step 3: Combine the Main Ingredients
Next, stir in your shredded cooked turkey, sea salt, black pepper, and minced parsley, combining them well. Gradually pour in 1 cup of heavy cream and 1 cup of shredded cheese, mixing until the mixture simmers gently. This rich blend forms the creamy base for your Turkey Broccoli Casserole.
Step 4: Transfer to Baking Dish
Carefully transfer the turkey and vegetable mixture into your prepared baking dish, spreading it evenly with a spatula. Make sure it’s nicely layer for even cooking. Top the casserole with the remaining shredded cheese, allowing it to melt beautifully during baking.
Step 5: Bake to Perfection
Place the casserole in the preheated oven and bake for about 20 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and starting to turn a lovely golden color. The aroma will fill your kitchen, inviting everyone to gather for a comforting meal.
Step 6: Garnish and Serve
Once done, remove the Turkey Broccoli Casserole from the oven and let it cool for a few minutes. Sprinkle with additional minced parsley for a fresh touch, and then serve it hot, enjoying the delicious layers of flavor in each comforting bite.
