Instant Pot Three Bean Enchilada Casserole Recipe

A little bit of spice and a whole lot of flavor, this Instant Pot three been enchilada casserole is one for the books! The cookbook that is. Three bean enchilada casserole is most definitely a dish to satisfy the taste buds.

Mexican dishes are one of my favorite things to eat, but I am kind of picky about them. I need there to be a lot of flavor with a little bit of kick and this vegetarian Instant Pot recipe does it perfectly. 


Not to mention, I secretly enjoy almost anything in a casserole. No need for extra side dishes and less to clean up. It sounds like a win-win in my book! 


My husband is also normally one that loves a good hearty meal, and he loves this recipe, even without meat! The beans in this recipe give you all the protein you need to leave you feeling full and satisfied.


A few of my other favorite meatless Instant Pot recipes are our Instant Pot Cheesy Penne Pasta, Instant Pot Mac and Cheese, and this Instant Pot Sweet Potato Casserole. All are deliciously flavorful and super simple recipes.

Here is how to make this scrumptious family dinner recipe:

Start by getting all of your ingredients together. Dice up the peppers and onion. Make sure to drain and rinse all of the beans in a colander before using them and cut the tortillas into strips.

Then, plug in the Instant Pot and turn it on the SAUTE setting. Add in the olive oil and diced red and green pepper, and the yellow onion and cook everything until they become soft. 

Next, turn off the SAUTE function by pressing the “CANCEL/KEEP WARM” button. Add in the green enchilada sauce, taco seasoning, rice, water, and the zucchini but DO NOT stir everything together, leave it as is. 

Once all of that is done, place the lid on the Instant Pot, lock the lid into place and be sure to turn the valve to the “SEALING” position. 


To start the Instant Pot press the “MANUAL” or “HIGH PRESSURE” button and set the timer for 4 minutes. 


Once the time has run out, turn the knob from “SEALING” to the “VENTING” position to do a quick release and remove the lid one all of the pressure has been released. 

After you remove the lid, add in the black beans, white beans, pinto beans, and the can of corn to the Instant Pot and stir everything until it is well combined. 

Next, add in the chopped cilantro and shredded Colby jack cheese and begin to fold it into the bean mixture until they are all combined. 

Now just the tortilla strips on top and serve it warm with all of your favorite enchilada toppings. 


A few Enchilada toppings we suggest:

  • Avocado
  • Pico de Gallo
  • Shredded lettuce
  • Sour cream
  • Salsa
  • Chopped jalapenos

  1. This recipe burned in my instapot. It wasnt that tasty either. The family seemed to enjoy it but i didn't. I found inaccuracies in the recipe, such as ingredients called for 2 c of enchilada sauce but directions say 1/2 c. Also it said to just mix in beans and corn, i guess b/c its hot enough and would make it all warm. That was weird to me, I prefer things cooked. It was confusing and i consider myself to be skilled in the kitchen. Disappointing and dinner took longer than necessary since instapot gave me burn notice, I had to selvage what i could and finish on stove top. Not a fan here.
  2. This sounds like something I’d like to make but I want you to clarify a point for me: the recipe asks for 2 C of green enchilada sauce but the instructions say add 1/2 C of enchilada sauce. I’m sure this is a typo, but which one is correct: 2 C or 1/2 C? Thank you for all the recipes y’all have put out there for us. I’m new to the Instant Pot & these recipes are great & easy to follow.

      I just made this tonight and thought that 2 cups seemed the more likely option. I can't speak for how the recipe is "supposed" to taste, but I can attest to the fact that it was delicious with the full two cups! It gave the finished product a nice consistency (not dry or anything), and it also had a good flavor. I also pressure cooked it for one more minute (with a quick release) after adding the beans and corn, just to make sure it all got nice and warmed up.
