  8. Bake for 30 minutes then remove from oven and let cool. Serve with toppings and enjoy!

FAQ’s:

Can you use a different ground meat?

Yes, absolutely. This recipe would be great with ground turkey, chicken, or bison.

Does it reheat well?

Yes! This recipe is perfect for meal prep. I just keep the toppings separate, so I can reheat the taco bake and then add the toppings after.

    I think this would’ve been a big hit but my beef was very chewy in the casserole. I’m not sure why? I would like to try again – any tips on how to avoid the meat becoming chewy? The flavors were really good but I couldn’t eat much with the texture.

    This is really good! I am all about bakes, casseroles, one pot etc. As soon as I saw this one- I had to try it. This was super easy to make and we all loved it. We ended up serving it bowl style with a little brown rice on the bottom of the bowl- alternatively could have use more cauli rice too. Topped with a fresh guacamole but anything would have been great! Both ways or alone would be yummy. I can’t wait to make this again!

    This was delicious! I drained the beef and onion mixture before adding the spices and cauliflower. Does that make a huge difference In the end result?

    I love how family friendly this is! The kids and husband ate this with tostadas and beans, but I earnestly couldn’t believe their compliments. I was thinking the dreaded “pickiness” would damper the meal, especially after hearing “is this white stuff onions?” I am telling no one it’s cauliflower rice! Topped with homemade guacamole and pico de Gallo – this meal comes together so quickly and could not be any simpler.

  5. 5 stars
    Made this for my family and loved it! Can I refrigerate it before putting it in the oven to pass to a friend to bake at a later time?

  6. What is the purpose of the eggs? I have an egg allergy. Wondering if I should replace with flax eggs? Thank you!

  7. 5 stars
    We had this for dinner this week and thought it was great and super easy! We used ground turkey. I think the seasonings used really makes the dish. Can’t go wrong with the yummy toppings as well! We will definitely make this one again!
