Step‑by‑Step Instructions for Veggie-Loaded Rotisserie Chicken Casserole
Step 1: Steam Vegetables
Start by bringing a deep pan of water to a gentle boil. Steam the broccoli and cauliflower for 15–18 minutes until tender but still vibrant in color; they should be fork-tender without becoming mushy. Once cooked, strain them well and set aside to cool, ensuring they’re dry to prevent a watery casserole.
Step 2: Sauté Aromatics
In the same pan, heat 1 tablespoon of olive oil over medium heat. Add the diced onions and sauté for about 2 minutes until they become translucent. Next, stir in the spinach and minced garlic, cooking until the spinach wilts and the garlic is fragrant, about 2–3 minutes. Take the aromatics off the heat and let them cool slightly.
Step 3: Mix Ingredients
In a large mixing bowl, combine the whisked eggs, Greek yogurt, and milk for a creamy base. Fold in the shredded rotisserie chicken, half of the cheese, the cooled vegetables, sautéed aromatics, and seasonings such as fresh herbs and spices. Mix everything gently until well combined, ensuring every ingredient is evenly distributed.
Step 4: Prepare Baking Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with olive oil or cooking spray. Pour the veggie-loaded mixture into the dish, spreading it evenly with a spatula. Top the casserole with the reserved cheese and sprinkle with crushed parmesan crisps for a crispy finishing touch.
Step 5: Bake
Place the casserole in the preheated oven and bake for about 35 minutes. You’ll know it’s ready when the top is golden brown and bubbly. If you desire an extra crispiness, broil for an additional 3 minutes, keeping a close watch to prevent burning.
Step 6: Garnish and Serve
Once out of the oven, let the Veggie-Loaded Rotisserie Chicken Casserole rest for about 10 minutes. This allows the flavors to meld beautifully. For a bright finishing touch, garnish with freshly chopped parsley before cutting into generous portions and serving warm.

Veggie Loaded Rotisserie Chicken Casserole Recipe FAQs

What should I do if my casserole turns out watery?
If you find yourself with a watery casserole, it’s often due to vegetables that weren’t fully drained after cooking. To prevent this next time, ensure that all veggies are thoroughly steamed or sautéed, then drained well before mixing them into the casserole. Adding an extra egg or a bit more Greek yogurt can also help bind the moisture.
Are there any dietary considerations for this recipe?
Very! For those with dairy allergies, feel free to substitute the cheese with dairy-free options. If you’re looking for a vegan alternative, replace the eggs with flaxseed meal mixed with water (1 tablespoon of flaxseed + 2.5 tablespoons of water serves as one egg). Always double-check with family members about their dietary needs when planning your meal!
