This Mexican quinoa casserole is not only packed with veggies and black beans, but is bursting with traditional Mexican flavors that the whole family will love. Vegetarian and gluten-free.

I’m excited because I have quite the recipe to share with you today. It’s vegetarian, packed with protein (18 grams per serving) and gluten-free. I think you’re going to like it… I *know* you’re going to like it!

When you think of healthy food, Mexican food isn’t typically the first thing to pop into your head (at least not for me). But you can certainly make Mexican dishes that are healthy and the recipe I’m sharing today proves it. This casserole has a mixture of veggies, quinoa, beans and cheese. A delicious and nutritious Mexican feast!

Ingredients in Mexican Quinoa Casserole

  • quinoa
  • vegetables – sweet potato, red bell pepper, yellow onion, green onion, cilantro
  • taco seasoning – make your own or purchase a pre-made blend.
  • canned black beans
  • salsa – use whatever heat type you prefer! We love spice so I used a hot salsa. The creamy bites of avocado and Greek yogurt were the perfect contrast to the spicy bites. Having said that, if you don’t like that much heat, mild salsa is just as delicious!
  • Mexican cheese blend
  • toppings of choice – I love topping this casserole with Greek yogurt, avocado, green onion and cilantro.

Prepping Mexican Quinoa Casserole

This dish does take a little bit of prep work because you have to chop all the veggies and cook the quinoa. But it’s worth it! If necessary, you can save time by prepping the whole bake ahead of time and then just pop it in the oven right before dinner time.

Start by cooking the quinoa. While your quinoa cooks, get to chopping. Chop all of the veggies right away! Add your sweet potato, red pepper and onion to the bottom of a greased casserole dish. Sprinkle taco seasoning evenly over all of the vegetables. In a large bowl, combine the cooked quinoa, beans, cilantro, green onion and additional taco seasoning. Spread the quinoa mixture over the sweet potato and red pepper layer. Next, add a layer of salsa. Add the cheese on top, cover with aluminum foil (to make sure the cheese doesn’t burn!) and bake. It will come out of the oven piping hot with a perfectly gooey layer of cheese. Yum!

Isaac and I LOVED this dish. Each bite is full of flavor and texture — a fiesta in your mouth, if you will. All the veggies are cooked to perfection so they taste fresh instead of overcooked and mushy.

    Brittany, I made this last night for dinner, and we loved it! I used 1.5 c cooked quinoa as I already had that in the fridge. I love how the moisture in the salsa is used to cook the veggies and keep them moist. I will definitely make this again, and again! Thank you for another great recipe!

    This was really yummy and so easy! I made the quinoa in my instant pot to make this even easier to throw together. We loved eating this with tortilla chips, like a dip or as nachos! I took the leftovers and used them as the filling for your enchilada recipe!

    I just SCARFED down my bowl of this, and am no longer sad that my husband won’t want any. I did double the sweet potatoes and bell peppers, just because they needed used, but goodness my heart and body needed this tonight! So so good, and I will now be going in for seconds!

    Let me just say dont even think twice about making this dish ! So easy but so delicious , I am a Mexicana and the flavors were on point I did make my own taco seasoning, added 2 zucchinis to the veggie mix , half a de-seeded jalapeno and instead of jarred salsa I used a small can of el pato jalapeno salsa as I’m not a fan of jarred salsa it was the best thing I’ve made in awhile🙌

    1. Ahh that makes me so happy to hear, Mel!! Thank you so much for coming back to leave a comment + star rating. It means the world to me. <3

    I made this using a mango peach salsa and only used a small even layer of a triple cheddar cheese. It came out perfect! Definitely one of my favorite dinner recipes!
