Recipe Overview
Time: 1 Hour
Ingredients: Chicken breast, bell peppers, onion, mushrooms, jalapeños, broth, sour cream, Ro-tel, green chiles, corn tortillas, cheese, flour, spices, garlic, olive oil.
Ease: Medium-hard, requiring you to cook vegetables, then chicken, and then bake everything in the oven.
Ingredients & Substitutions

- Chicken Breast - you can use any cut of chicken you want - chicken breast, chicken tenderloins, chicken thighs. You will need 2 pounds and to cut them into small bite-sized pieces. You can also use shredded chicken - you will need 3-4 cups. You can mix the shredded chicken with the seasoning to give it even more flavor.
- Mushrooms - Although actual mushrooms aren't traditional in King Ranch Chicken casserole, since we aren't using crema de mushroom soup, we are adding fresh mushrooms to provide that flavor. Any kind of mushroom works.
- Jalapeños - Optional, it adds a little spice to the dish, but if you don't want to use jalapeños, you can use ½ teaspoon of chipotle chili powder or cinnamon powder.
- Broth - We are using broth to replace the canned mushroom and cream of chicken soup. You can also use vegetable broth. Beef broth would give the dish a different flavor and browner color.
- Sour Cream - gives the dish a creamy texture. Add ¼ cup more of sour cream for an even creamier dish
- Canned Ro-tel and Green Chiles
- Corn Tortillas - Corn tortillas are the way to go for this recipe. It gives you the right texture and flavor. White corn and yellow corn tortillas will give you the same flavor and texture. You can use flour tortillas, but the dish will be breadier and softer.
- Cheese - Cheddar cheese (sharp gives the strongest flavor) is the classic go-to for a ranch casserole, but you could also use Monterey Jack cheese or pepper Jack cheese.
- Garlic Cloves - If you don't want to use garlic cloves, you can use ½ teaspoon of garlic powder.
