Step‑by‑Step Instructions for Veggie-Loaded Rotisserie Chicken Casserole
Step 1: Steam Vegetables
In a deep pan, bring water to a boil and steam the broccoli and cauliflower for about 15-18 minutes, until fork-tender and vibrant. Once cooked, strain the vegetables and set them aside to cool while you prepare the other ingredients for the Veggie-Loaded Rotisserie Chicken Casserole.
Step 2: Sauté Mix
In the same pan, drizzle olive oil and heat over medium heat. Add the diced onions and sauté for 2 minutes until they become translucent. Then, stir in the fresh spinach and minced garlic, cooking until the spinach wilts and the garlic becomes fragrant, about 2-3 minutes. Allow this mixture to cool before incorporating it into the casserole.
Step 3: Combine Ingredients
In a large mixing bowl, whisk together the eggs, Greek yogurt, and milk until smooth. Add in the shredded rotisserie chicken, half of the cheese, and the cooled vegetable and sauté mixture. Season with your chosen herbs, spices, and a pinch of salt and black pepper, mixing until fully combined for your Veggie-Loaded Rotisserie Chicken Casserole.
Step 4: Transfer and Top
Preheat your oven to 375°F (190°C) while you prepare the baking dish. Lightly grease a 9×13 inch baking dish with olive oil or cooking spray. Pour the creamy chicken and vegetable mixture into the dish, spreading it evenly. Sprinkle the reserved cheese on top followed by the crushed parmesan crisps to create a delightful crispy topping.
Step 5: Bake
Place the casserole in the preheated oven and bake for approximately 35 minutes. You’ll know it’s ready when the top is golden brown and bubbling around the edges. For an extra crispy finish, switch the oven to broil and cook for an additional 3 minutes, watching closely to avoid burning.
Step 6: Serve
Once the Veggie-Loaded Rotisserie Chicken Casserole has finished baking, remove it from the oven and let it rest for about 10 minutes. This resting time allows the flavors to meld together beautifully. Optionally, garnish with fresh parsley before serving for a pop of color and freshness.
