This Instant Pot Enchilada Casserole is a delicious one pot Mexican chicken recipe that is ready in 30 minutes or less – it's also gluten-free!
Making this recipe in a slow cooker
If you aren’t the lucky owner of an electric pressure cooker, it is not a problem at all! You can make this Instant Pot enchilada casserole easily in a slow cooker instead.
Simply add all of the ingredients to the slow cooker, with the exception of any fresh toppings. Then, allow it to cook on low power for 6 hours, or until all of the liquid is absorbed into the quinoa.
Side dish ideas
When you're thinking of what to serve with a chicken enchilada casserole like this one, think of what you would typically serve with any Mexican dinner.
A side of tortilla chips and salsa would be nice, or a garden salad would be great for some additional healthy veggies.
- olive oil – Any neutral flavour of cooking oil like avocado or vegetable oil will also work
- boneless skinless chicken breasts – You’ll be dicing the chicken, so fresh tenders are a good substitute. If you prefer dark meat, you can use boneless skinless chicken thighs instead
- taco seasoning – Many store bought seasoning mixes include MSG as a preservative. If you would like to avoid it, you can use homemade taco seasoning
- minced garlic – Fresh cloves of garlic provide the most flavour, or you can use jarred garlic
- onions – I prefer yellow onion but white and red onion are fine too
- chicken broth or stock – Vegetable broth may be used instead
- tomato sauce – Cans of diced tomatoes will also work. Or, in a pinch, you can use your favourite pasta sauce, but you may need to add some water to thin it out
- uncooked quinoa – I prefer white, but any colour quinoa will be fine
- bell peppers – I like to add colour, so I use 1/2 each of red, green and yellow bell peppers
- shredded cheese – Cheddar, Parmesan, or even a Mexican cheese like Cojita would be great
- diced avocado – To keep your avocado fresh and prevent it from discoloring, squeeze a little bit of fresh lime juice over the pieces.
- plum tomatoes – I like using plum tomatoes because they tend to have less seeds, but any variety of tomato will be fine.
- fresh cilantro– Feel free to use parsley if you aren’t a fan of cilantro
Storing and reheating
Allow the casserole to cool down before transferring it to an airtight container. Keep it in the refrigerator and use it within 5 days.
You can reheat it in a pan on the stovetop over medium heat, in the microwave, or even in your Instant Pot.
To reheat the meal in your pressure cooker, you’ll want to use the simmer or sauté function. You’ll first need to remove any fresh toppings, like the avocado and shredded cheese. Stir it occasionally until it heats through.
Freezing this recipe
Instant Pot chicken enchilada casserole will freeze well for up to 3 months. Cool the meal to room temperature before transferring to airtight freezer-safe containers. To thaw, place the casserole in the refrigerator overnight before reheating it.
If you want to freeze it in individual containers for easy meal prep, it can be taken right from the freezer to the microwave. Reheat it on high power for a few minutes, stopping at least once to stir it.
