What Makes This Recipe So Good

  • There’s a ton of delicious flavor here! Rich salsa, tender rice, savory black beans, zesty cheese, and your favorite taco seasoning baked into one delicious vegetarian dish.
  • Mexican rice casserole is a one-dish dish! Just dump all the ingredients in the casserole dish, stir well, and pop it in the oven. No dirtying multiple bowls or utensils, and even better – no cleaning multiple bowls or utensils.
  • This is a slow-bake recipe, which gives you time to do other things. No running back to the oven to stir every few minutes or anything like that. This dish takes care of itself! To make things even more convenient, feel free to do the prep work earlier in the day and then just put the casserole in the oven about an hour before you’re ready to eat.

Chef’s Tips

  • The rice really controls the baking here, so use it as your guide. After 50 minutes in the oven, uncover the dish and taste the rice. If it’s tender, you’re ready to move on to the next step. If it’s still firm or crunchy and undercooked, put the foil back on and put the dish back in the oven for 10 or 15 minutes. After that, test it again and move forward if it’s tender.
  • Don’t worry if the Mexican rice casserole is a little loose or liquidy after you remove the foil, before you add the cheese. It’ll firm up as it rests after baking and be the perfect consistency.
  • Feel free to add any of your favorite toppings not mentioned here. A squeeze of lime, a sprinkle of diced onion or jalapeño, or a drizzle of queso would all be delish. You can also serve the casserole with tortilla chips or even slices of bell pepper to act as chips.

  • After 50 minutes, remove dish from oven and uncover. Taste rice to gauge texture. If rice is tender, leave dish uncovered, sprinkle remaining cheese on top, and return to oven to bake another 10 minutes or until cheese is melted.
    Alternately, if rice still has some bite (i.e. is firm or crunchy) then replace foil cover and return to oven to bake another 10 to 15 minutes. Test rice again; once tender, add remaining cheese to top and return to oven for 10 minutes.
  • Once cheese is melted, remove dish from oven. Let stand 10 minutes, then garnish with green parts of green onions, cilantro, avocado, and/or sour cream. Serve warm.
  • If the casserole is a little loose or liquidy after removing the foil, that’s fine. It’ll firm up as it rests for 10 minutes in step 4.

  1. Can I use brown rice?

    1. Avatar Jessica | 40 Aprons Team says:

      Brown rice cooks for a different amount of time, so you would need to adjust the timing accordingly!

  2. Can I make this in a slow cooker?

    1. Avatar Jessica | 40 Aprons Team says:

      We have not tried it, so we can’t say for sure! So sorry!

  3. This recipe is really good. If I used plant base burger meat would I cook it first and add more broth?5 stars

      I’m not familiar with cooking plant-based ground “beef”, unfortunately, so I can’t say offhand how long it needs to cook or what the results would be. We didn’t test this recipe with it. That being said, if the meat substitute you’re using would be fully-cooked within the 60-minute bake time, I would imagine you could skip cooking it beforehand. You may need more broth just depending on how much liquid the ground “beef” would absorb.

      So glad you enjoyed it, Michela! 😊

  5. This recipe is amazing! I added chopped sweet peppers for more veggies and cojita cheese with the Mexican cheese and jalapeño style green salsa instead or regular salsa and it was AMAZING! I made my own taco seasoning so it was less sodium since salsa and cheese have all the sodium you will need for this recipe! It’s so easy and filling5 stars

    1. Avatar Jessica | 40 Aprons Team says:

      Sweet peppers, cojita cheese, and green salsa sound like delicious additions to this dish! Thanks for sharing, Rachel! 😊

      1. This looks so good!! I’m wondering if I could add hamburger ?

        1. Megan | 40 Aprons Team Megan | 40 Aprons Team says:

          Sure! It just wouldn’t be vegetarian at that point.
