Recipe Notes

Here are a few tips and tricks to make this low carb taco casserole as effortless as it claims!

Ingredient Notes

Ground turkey – Taco casseroles are often low carb ground beef recipes, but we mixed it up with ground turkey. You can buy this in the store, or make your own by pulverizing turkey breast in a food processor. You could also sub in ground chicken or beef if you’d prefer!

Honestly, the seasoning is going to make them all fairly similar, so feel free to mix it up!

Low carb taco seasoning – make sure to check the packet nutrition label, most store bought mixes have lots of hidden sugar. You can also use my recipe, which keeps the sugar out but all of the flavor in.

Shredded cheese – You can buy this at the store which saves you some steps and dishes.

Tools To Make

Casserole dish – This recipe calls for some ingredients to be cooked in a pan before layering it all in a separate casserole dish. You can save yourself a little cleanup and combine it in a heavy iron pan to make a low carb taco skillet.

Can You Freeze This?

You can absolutely freeze this low carb taco casserole, before or after you bake it. Keep off the fresh ingredients, and wrap tightly in saran wrap or put in an airtight container.

If you freeze it before you bake it, let it defrost in your fridge before you bake it, or make sure to add on some additional baking time.

Meal Prepping Tips

This is one of the great healthy dinner ideas right at your fingertips all week! After baking, slice into 8 pieces and store in the fridge or freezer in airtight containers.

Whenever you need a meal, just take one out and warm in the oven, toaster oven or microwave. This also make a fantastic low carb breakfast casserole, so you can have a hot and scrumptious meal to start your day in no time at all!

Recipe Variations

Here are a few variations you can try to make this low carb taco casserole recipe your own:

How Can I Add More Veggies?

Casseroles are an amazing place to pack in all of the veggies we try and eat in one day. Feel free to mix in whatever you have on hand, or whatever you’re craving to this low carb taco casserole recipe!

Some delicious additions include cauliflower rice for a cauliflower rice casserole drenched in cheesy deliciousness. I also like adding green beans into the mix, as low carb green bean casserole adds a delicious crunch and a healthy dose of fiber.

To take things up a few culinary notches, try stuffing the filling for this casserole into hallowed out and blanched zucchini’s for fantastically delicious zucchini enchiladas!

Can I Use Different Types Of Meat?

Don’t have any ground turkey on hand? Stay with the poultry and turn this into a yummy low carb chicken casserole or easy ground chicken casserole.

If you’re looking to add in some omega 3s, you can sub in canned tuna for a scrumptious low carb tuna casserole that puts all other tuna dishes to shame!

Can I Use Other Kind Of Cheese?

Totally! Currently, we’re using the classic cheddar, but if you want to use what you have in the pantry, simply swap.

Pepper jack or Mexican cheese blend would be delicious! Or mozzarella for Mexican lasagna vibes. (Check out these tasty low carb lasagnas for inspo: zucchini lasagna and cabbage lasagna)

How Can I Add More Protein?

This dish has got 37 grams of protein per serving!!! Thanks to the ground beef we’ll be using as the star ingredient (think of this as a low carb meatloaf full of zesty veggies and spice mix).

BUT, if you want to increase to protein amount even more, and potentially cut down your serving size, just double the meat AND spice mix. This would also cut down the carbs per serving, as the protein and fat content would increase.

Can I Add Squash?

Squash is so amazing and versatile and absolutely packed with nutrients and antioxidents. Bring out their best gifts by sautéing your squash of choice with the other veggies in this dish — low carb squash casserole, never disappoints!

If you’re missing the pasta addition to most casseroles, try mixing in cooked spaghetti squash for a taco spaghetti squash casserole you’ll ADORE!
