Step‑by‑Step Instructions for Veggie-Loaded Rotisserie Chicken Casserole
Step 1: Steam Vegetables
Begin by steaming freshly cut broccoli and cauliflower in a deep pan with a steaming basket over boiling water. Steam the veggies for about 15-18 minutes until they are tender but still vibrant in color. Once cooked, remove them from the heat and strain to eliminate any excess moisture, then set aside for later use in your Veggie Loaded Rotisserie Chicken Casserole.
Step 2: Sauté Aromatics
In the same pan, heat 2 tablespoons of olive oil over medium heat. Add diced onions and sauté them for about 2 minutes until they become translucent. Next, incorporate the minced garlic and spinach, cooking until the spinach wilts beautifully, which should take an additional 2-3 minutes. This aromatic mixture will elevate the flavor profile of your casserole.
Step 3: Mix Ingredients
In a large mixing bowl, whisk together the eggs, Greek yogurt, and milk until well combined. Stir in the shredded rotisserie chicken, half of the cheese, steamed vegetables, sautéed aromatics, and season with fresh herbs, red chili pepper flakes, black pepper, and salt. Mix thoroughly until all ingredients are coated in the creamy mixture, creating a colorful blend for the Veggie Loaded Rotisserie Chicken Casserole.
Step 4: Transfer to Baking Dish
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or a drizzle of olive oil. Pour the chicken and vegetable mixture into the prepared dish, spreading it evenly to ensure uniform cooking. Top it off with the remaining cheese and sprinkle crushed parmesan crisps over the surface for an irresistible crunchy topping.
Step 5: Bake
Carefully place the baking dish in the preheated oven and let it bake for about 35 minutes, or until the top is bubbly and golden brown. Keep an eye on it and, for an extra crispy finish, consider broiling for an additional 3 minutes, watching closely to prevent burning. The delicious aroma will fill your kitchen, promising a comforting meal.
Step 6: Garnish and Let Rest
Once baked to perfection, remove the Veggie Loaded Rotisserie Chicken Casserole from the oven and allow it to rest for about 10 minutes before serving. This resting time lets the flavors meld beautifully and makes it easier to slice. Optionally, you can garnish with freshly chopped parsley to add a pop of color and freshness right before enjoying your meal.
