Vegetarian Mexican Casserole Ingredients
I love a recipe that uses up canned food in a way that doesn’t taste like canned food. Combining canned food with fresh ingredients like sour cream and cheese really makes this easy and cheap meal taste delicious.
- uncooked jasmine rice or white rice
- can corn, drained
- can black beans, drained and rinsed
- salsa (any salsa works)
- vegetable broth
- taco seasoning
- Mexican style cheese
- Toppings
- Avocado, sour cream, diced tomatoes, shredded lettuce, etc (for topping)

How to Make Vegetarian Mexican Casserole
Usually, my Mexican casseroles require some prep before you bake them, like if they have ground beef or chicken, you have to cook the meat before. And that might not seem like a big deal, but that takes an extra 10 minutes and dirties at least one skillet and one utensil, which adds another couple of minutes to clean. When I want a fast and easy dinner, I want a fast and easy dinner.
Thankfully, this Vegetarian Mexican Casserole is so fast and easy and only dirties one dish– the one that it’s baked in!
Step One: Mix
Directly into the greased baking dish, add the rice, black beans, salsa, vegetable broth, taco seasoning and half a cup of cheese. Mix that all up well and cover with foil.
Step Two: Bake
Bake for 50 minutes. After your timer is up, remove from the oven, discard the foil, stir the ingredients around in the baking dish, and top with the remaining cheese. Bake for an additional 12 minutes, uncovered, or until the cheese is melted and bubbly.
Step Three: Eat
Scoop a big helping onto your plate, top with your favorite taco toppings, and enjoy!

Big fan of Mexican food over here. I’m from New Mexico, so I grew up with a ton of great Mexican food. I won’t lie and say this is authentic but it sure is tasty! If you like to make Mexican-inspired dishes at home, here are a few more recipes that I think you’ll love.
Just made this, and it’s very good! It’s pretty customizable so there’s no fuss if you need to swap ingredients. Good meal for those nights when you want to throw something together and not order from the delivery apps!
Could this be done in the slow cooker?
This was wonderful on a cold, rainy day! I was out of white rice so swapped it out with saffron rice and used a tomato stock. I had a three pepper & onion blend I needed to use so I threw that in too. It came out so flavorful & was so easy to make! There’s so many ways you can adjust to adapt to your family’s preferences and I love having that wiggle room with these recipes. Thanks for another winner Julia!
This turned out so well! I was worried about the rice being undercooked, but it was perfect. I was pleasantly surprised by this recipe. I love beans & rice, but this is more flavorful. I loved how easy and fast it was. Will definitely make this again!
Thanks Julia – This was great. A very nice Mexican rice dish. I just noticed that in the Youtube video, you sprinkle ranch powder on the dish, but don’t mention it in either the video or the recipe here. I’m going to have to try it with the ranch next time.
So simple and sooo delicious! Looking forward to making this again.
My Daughter is a vegetarian, and finding a meal that the whole family enjoys is difficult. But we really enjoyed this! We topped it with sour cream, guacamole, and salsa. Also used it as chip dip too!
This is now a staple in our home! So quick to throw together, delicious, and easy to stretch out the leftovers into “extra” meals. Love this recipe!
We really enjoyed this recipe! Of course, I added diced jalapenos since we like a little extra spice!
We tried this last night and it was delicious! I’ve been trying to find inexpensive meatless meals, and this fits the bill. We had a little sour cream and tortilla chips with it, and my husband loved it. He was excited there were leftovers for lunch! We *may* have put a bit more cheese on top than listed in the recipe…
Made this last week and it was delicious! I have low iron so I added a pound of ground beef that I browned beforehand, and used chicken broth instead of vegetable broth. This stretched out for 3 nights of dinner for my husband and myself. I am definitely going to start making this a few times a month. Next time I might serve on tortillas as it tastes like burrito filling. Delicious recipe!
I saw this recipe on a recent video. It looks delicious! I can’t wait to try it. I’ve been looking for some easy week night meals. Thanks for sharing,
