How to Make Instant Pot Mexican Rice Casserole

  • This Mexican Rice Casserole has all of our favorite ingredients in ONE pot! I love the Instant Pot because you can sauté right in the Instant Pot. This is a great one pot meal!
  • We combine brown rice, black beans, pinto beans, diced tomatoes, green chiles, red bell pepper, garlic, onion, lime juice, lots of spices, and vegetable broth in the Instant Pot and let it do it’s magic.
  • When the Instant Pot is done, we stir in corn, shredded cheese, cilantro, and green onion. The cheese melts into the rice and black beans creating the perfect cheesy rice and bean casserole!
  • We serve the casserole in bowls and top with avocado slices. The boys like to eat their casserole with tortilla chips. They are all about dipping!
  • This easy rice casserole reheats well, making great leftovers for lunch or dinner all week. It also freezes well. I love keeping a container in the freezer for busy weeknights. Defrost and heat up in the microwave!
