You’re not going to believe how delicious a healthy, vegetarian Mexican quinoa casserole can be until you’ve tried it.

Yes, healthy casseroles do exist.

How do you make a vegetable casserole?

The funny thing is I actually intended to include chicken in this recipe but when I got home, I found our rotisserie chicken had been turned into a soup by the Mr. Fine! I’m not complaining. I love that I’m not the only one who cooks around here, ya know what I’m sayin?

So I had to get a little creative a take this casserole in a vegetarian direction. What I decided to do was come up with a vegetarian replacement for the texture and flavor of the meat.

I decided to use a combination of refried beans, quinoa to make a faux “meat.” Once the vegetables, cheese and enchilada sauce blend with this combo, you don’t even realize you’re missing the meat.

Could you make this Mexican casserole with meat?

If you’re not a vegetarian and you want to mix things up by making this using meat, you can do that. Shredded chicken or ground beef would work well in place of or in addition to the refried beans and quinoa. Just include a layer of chicken, beef or pork and everything else stays the same.

Is this vegetarian casserole freezer safe?

Yep! You can make ahead and freeze the whole casserole or you could precook the quinoa and keep that ready t go in the freezer so all you have to do is microwave it to defrost, then prep the casserole. You can also freeze diced peppers or buy peppers already deiced. This cuts out a bit of prep time and makes things easy to prepare on a weeknight.
