Plant-Based Slow Cooker Mexican Quinoa Bake

Whether you’re relying on pantry staples or you’re looking to add more plant-based recipes into your life, this quinoa bake has you covered!

You can spruce it up with common ingredients you may have on hand, but it relies on a handful of foods you may already have in your kitchen. It’s packed with plant protein goodness from quinoa and gets an extra boost from flaxseed!

This recipe is naturally vegan, but you can stir in cooked ground beef or chicken or top your serving with cheese if you prefer. You can customize your spice level though which salsa you use and you can top the bake with chopped jalapeños if you want an extra kick.

We know there is a strong debate over flavors like cilantro, so this is the perfect recipe to turn “build your own.” Consider serving it up with toppings like chopped tomatoes, avocado, shredded cheese, cilantro, sour cream, and lime wedges — then everyone gets their bowl exactly the way they like it!

Serve this bake in bowls by itself or with tortilla chips on the side as a new take on nachos! If you try this out, we would love to hear about it — tag us @manitobamilling!

Slow cook times can vary, so check the quinoa while cooking to see if you need to add or subtract cook time. You will know the quinoa is ready when the seeds are fluffy and tender and some of the yellow rings have “sprung” from their seeds. Seeds should no longer be crunchy.
