This Whole30 taco casserole is an awesome meal prep recipe or perfect for a paleo or gluten-free weeknight meal. Preparation is simple, just mix everything together, oven bake it, and pull out a delicious beef taco casserole for the family! It’s a great way to use up ground beef, and it’s healthy recipe option that’s loaded with veggies that can be enjoyed with a ton of different toppings depending on what you prefer!

Gather Your Ingredients!

All of the ingredients you’ll need for this Whole30 taco casserole are really common, easy-to-find ones. You’ll need ground beef, green peppers, an onion, potatoes and eggs. Then you’ll need three canned items, black olives, green chiles (you can use mild or hot, depending on your preference), and diced tomatoes. Make sure to drain the canned items really well or you’ll have some excess liquid that ends up in the casserole.

You’ll also need salsa, and a handful of spices, all which are likely already in your cabinet. I get my spices and salsa from Thrive Market for a discount (new members get a $20 shopping credit!), but they’re also really easy to find at most common grocery stores! Just make sure the salsa you grab is a no-sugar added one!

Steps to Making This Whole30 Taco Casserole

After preheating the oven, you’ll get to work on the ground beef. To transform it into taco meat, you’ll first add it into a large skillet to begin browning it. As it’s browning, add in all of the spices and the diced onion and combine it all together. Once it’s mostly all browned, grab a strainer and transfer the taco meat into it. It’s important to drain all of the grease really well so that it doesn’t end up in the bottom of the casserole!

From there, the rest is easy! Dump in all of the remaining ingredients into a casserole dish and stir it up to incorporate everything together evenly. This recipe does use beaten eggs as a binder, but if you’re egg-free, or want to skip this step, you can. The casserole won’t hold together well, but it’s still really good!

Pop it into the oven and bake it for 45 minutes to an hour, or until the potatoes are soft enough to be pierced with a fork. This will depend a bit on what size your casserole dish is and how thin or thick the ingredients are in it.

Add Fun Toppings!

There are so many ways to enjoy this Whole30 taco casserole. You can eat it over greens, like a taco salad. You can eat it on top of large bell pepper slices, in lettuce wraps or cups, you could have it over white or brown rice if you’re not eating Paleo or Whole30, the options are endless. There’s an equal amount of toppings you could choose to add, depending on what you or your family enjoy. Add avocado or guacamole, pico, (dairy-free) sour cream, more salsa, hot sauce, sliced jalapeno, more black olives, or whatever you have on hand and would like!
