How to Make Chicken and Vegetable Casserole – Step-by-Step
Step 1 – Prepare the Ingredients
Preheat your oven to 350°F. Dice the peppers, onion, and tomatoes, then mince the garlic. Chop the kale and set aside. Preparing vegetables ahead ensures even cooking and better flavor balance. According to USDA guidelines, always wash fresh produce under running water before use.
Step 2 – Mix the Casserole Base
Place peppers, onion, tomatoes, kale, garlic, and taco seasoning in a large bowl. Drizzle with oil and toss well to coat, massaging the seasoning into the kale. Add chickpeas, shredded chicken, yogurt (or mayonnaise), salt, and pepper, then mix thoroughly.
Step 3 – Assemble and Bake
Spread half of the mixture into a greased casserole dish and sprinkle with half of the cheese. Repeat with the remaining mixture and top with cheese. Cover with foil and bake for 30 minutes, then uncover and broil for 3–4 minutes until the top is golden brown.
Step 4 – Serve and Enjoy
Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with fresh herbs or extra cheese if desired. This dish pairs well with a side salad or roasted vegetables.
