How to make it
(This is a summary with step by step photos, full recipe measurements and instructions are in the recipe card below.)
Remember to soak your beans, either the night before or about 6-8 hours before you plan to make your Instant Pot Mexican casserole.
If you’ve forgotten to soak the beans, see my quick soak method in the notes of the recipe card below.
Now gather your ingredients.
Add the soaked beans, along with all remaining ingredients into your Instant Pot. Mix well and set to high pressure for 30 minutes. (photos 1-2)
If you’re new to using an Instant Pot, plan for about 10 extra minutes for the pot to reach pressure. Plus you’ll need another 10 minutes to naturally release, before quick releasing the remaining pressure.
So even though this dish cooks for 30 minutes, allow yourself 50 minutes of cook time from start to finish.
Serve warm, garnished with any of your favourite toppings.
What toppings should I use?
The options are almost endless here!
I like mine topped with diced tomato, fresh cilantro, white onion, sliced avocado and a squeeze of fresh lime.
Can I add anything else?
I’ve kept this simple but if you want to add more ingredients, you definitely can! Some great options include:
- frozen corn
- chopped onion
- bell pepper
How long does it keep?
Your Instant Pot Mexican casserole will keep refrigerated for 3 days. Just reheat in a pan on stove top, adding some water or broth to loosen, if needed.
Can I re-purpose this dish?
You can easily turn this dish into a taco casserole by adding your rice and beans to the base of a serving dish and top with tortilla chips, olives, jalapenos, and corn. Then add some vegan mozzarella cheese on top and bake in your oven to slightly melt your cheese.
For firmer beans, skip the soaking. For softer, melt in your mouth beans, soak them overnight, or 6-8 hours.
If you forgot to soak your beans, you may use this quick soak method. Add your beans to a pot and cover with water leaving at least 2-3 inches of water above the beans. Bring to a boil, remove from the heat and cover the pot with its lid and soak for 1 hour.

- Drain your beans and add all the ingredients to your Instant Pot. Mix to combine, then close the lid, ensuring the valve is set to the sealing position. Set on high pressure for 30 minutes. (It will take about 10-15 minutes to build pressure before counting down.) Let it naturally release for 10 minutes, and then quick release any remaining pressure.
