Ingredients and variations

Here’s what you’ll need to make this chicken taco bake. See the recipe card below for full details.

Oil – vegetable or avocado oil, for sautéing. You can use olive oil too.
Green pepper
Onion
Cooked chicken breasts – we like to use cubed grilled, pressure cooked, or rotisserie chicken, but shredded chicken also works! For a different texture, you an also use a pound of lean ground beef or ground turkey, or even a plant-based ground meat alternative.
Corn – we use canned corn, but frozen will also work.
Black beans – can sub pinto, or leave them out if beans aren’t your favourite!
Diced tomatoes with green chilies – we used mild Rotel to keep it kid friendly.
Taco seasoning mix – use your favourite store-bought packet or 3 tablespoons of homemade seasoning.
Garlic salt – or a mix of regular salt and garlic powder.
Sour cream – can sub full-fat plain Greek yogurt for a higher protein, lower fat option.
Tortilla chips
Shredded Colby Jack cheese – can sub regular cheddar, Monterey Jack or a Mexican blend.

How to make it

First, sauté the onion and green pepper in a large skillet, until softened and fragrant.

Next, add the cooked chicken, black beans, corn, taco seasoning, garlic salt and diced tomatoes with chilies. Mix until combined and continue to cook for about 5 minutes, stirring occasionally to heat it through. Add some of the reserved tomato liquid, if necessary.

Tips for success

Use a rotisserie chicken to save time. Meal prepped shredded chicken is also a great time saver. Just note that your leftovers will have a shorter shelf life if you’re not using freshly cooked chicken. If you’re making your own chicken, be sure to season it well (salt and pepper at minimum!). We also love this recipe to use up frozen chicken (two ~8oz breasts) and we use this recipe for cooking chicken breast from frozen in the Instant Pot.
Choose full-fat dairy for the creamiest result. Low fat dairy (like low-fat Greek yogurt) can separate when you stir it into a hot dish.
Drain excess liquid from the tomatoes and add back the reserved liquid only if necessary. This helps to avoid a watery texture.
If you have time, let the casserole rest for 5-10 minutes so that it will be easier to serve.

What to serve with Chicken Taco Casserole

Rice – the casserole has tons of flavour so you can get away with plain white rice, but you could also go with a variation like cilantro-lime rice
Guacamole or diced avocado – adds creamy texture and fresh taste
Salsa – pico de gallo or salsa verde are fresh and tangy options
Salad – a light, crisp green salad with a citrusy vinaigrette would balance the richness of the casserole
Tortilla chips or strips – for crunch and scooping up the casserole
