Recipe Ingredient Notes
This recipe is great because you can add just about any vegetables or taco ingredients that you want. Here’s what we used, and a few suggestions for substituting!
- Ground Turkey – you can totally substitute ground beef if that’s the taco meat you prefer. My husband personally hates ground turkey so I’ve made this with both.
- Yellow Onion
- Cooked Quinoa – cooked brown or white rice can also be substituted. You’ll want to keep the measurement the same, so it will be about two cups of cooked rice.
- Chopped zucchini
- Red Pepper
- Black beans – you can add pinto beans if you prefer those instead!
- Salsa – use your favorite salsa! We usually stick with mild, but if you want to add a little spice, go ahead and add a medium or hot salsa.
- Taco Seasoning – we usually just buy this in order to save on time, but if you have a good homemade recipe, that works great too. You’ll want about 2 Tablespoons.
Equipment Needed
For this recipe, you only need a few simple kitchen tools. We recommend using the following equipment:

Note About Quinoa
We don’t use quinoa in a lot of our recipes, and honestly, I’m not sure why. Quinoa is quick and easy to cook up a few cups. Plus, there are some great benefits of quinoa, such as high in fiber, good source of protein, gluten-free, great source of iron and magnesium, and contains antioxidants.

This looks like a wonderful recipe! I can’t wait to try it. Do you have any nutritional information to go along with this recipe? That would be great.
Look delicious!! Would I be able to replace quinoa with brown rice and still bake it in the same way?
I replaced it with brown rice yesterday and it worked great!
Are the black beans rinsed and drained?
We usually rinse and drain our black beans.
I made this the other night. I totally expected a mini family revolt, as we tend to not like “things together” i.e. casserole style. The pre-dinner discussion was no one had eaten it, including the cook, so we were “going to try it, and if we didn’t like it, we could express that and no one would have hurt feelings. I wanted an easy and fast cooking experience. We changed several things to make this recipe work for our family. We used ground sirloin instead of turkey, frozen brown rice (pre-microwaved for 3 minutes) instead of quinoa (we only used 1 1/2 cups because that is what came in the package), peeled and deseeded, then diced the zucchini and pre-microwaved it for 2 minutes (to jump start the cooking time), left out the red pepper, drained 1 can pinto beans instead of black ones, used the salsa (added it to the meat and wish I had added the taco seasoning to the meat with it to get it to pre-dissolve better; so, as not to have as strong of a chili powder hit as ours had. We also added two cups of frozen yellow corn pre-microwaved for 5 minutes. Added about 3 tablespoons of butter for richness and we did doubled plus the cheese on top and added a dallop of sour cream to each serving (and some even had ranch dressing as a topper). We mixed the ingredient (minus the sour cream all together and baked it for 30 minutes. The vote was to have warmed leftovers in a warmed flour tortilla and to add this recipe occasionally to the dinner lineup. Pleasantly happy with the outcome. Even my picky spouse voted for it again. Happy and surprised indeed!
I was hoping for this as well.
Is it 2 cups dry quinoa or cooked? Think I added too much!
I’m wondering if you would be able to add serving size to your recipe. The nutritional values are posted in them but never the serving size.
Thank you for sharing your cooking talents with the world. 🙂
I was wondering this, too! My quinoa turned into four cups cooked. I only added about 2/3 of it to the mix because it seemed like too much. Any insights anyone?
Hi there. Is the 2C of quinoa cooked? Thank!
Yes, 2 cups cooked.
Can I use cauliflower rice instead?
Are you thinking to use cauliflower rice in place of the quinoa? We haven’t tried this recipe with cauliflower rice. I’m sure it would work. You would want it cooked before adding it in.
This was the best thing I have eaten all summer. Used my homemade salsa for extra flavor. Should be on the front page of you website!
Could this be made into a frozen meal? If so, how?
We have not yet tried making this into a freezer meal.
Can you use cauliflower rice instead?
I think that should work great. Let us know how it turns out if you try it!
