How to Make this Easy Keto Taco Casserole Recipe
Preheat and Prepare
Start by preheating the oven to 350 degrees F. Then pull out a casserole dish and spray it with a non stick spray. Use coconut oil, avocado oil, or ghee spray. We don’t mess with canola oil sprays on keto. The same thing goes for other sprays made from highly processed vegetable oils – because yuck!
(When it comes to highly inflammatory cooking oils, we do)
Just because the American Heart Association tells you vegetable oils are heart healthy doesn’t make it true. Have you seen the health of most Americans following these guidelines?
In reality, highly processed vegetable oils go a long way in damaging your health. Throw them away if you have any lingering in your pantry. Don’t even vow to use what you have leftover – the damage just isn’t worth the pennies you’ll save.
Brown the Beef
Next, brown ground beef over medium-high heat in a large skillet. Crumble the beef while it cooks. After it browns, you may need to drain excess grease.
Once fully browned, stir in the water and taco seasoning. Use the prepackaged stuff if you’re in a hurry, but whipping up a homemade taco seasoning is a great way. to get less junk in your keto diet. Most pre-made seasonings have sugar and additives. When you make your own – you get to choose the delicious Mexican flavors you want to combine into the ground beef mixture.
It’s always best to choose the highest quality ground beef you can afford. Organic and grass-fed are your best options. If it’s hard to find high quality meats at your local grocery store, check out Butcher Box. The best part of ordering through this company is they deliver delicious low-carb ground beef right to your door each month.
Likewise, do your best to avoid ground turkey or lean ground beef in keto recipes. Keep in mind, if you’ve developed a preference for meats lower in fat, this is a sign your digestion could use some work. Since you need to eat enough fat to get into ketosis – meats with a higher fat content work best. Plus, higher fat meats have a great taste.
If you’re not accustomed to the amount of fat you need to find success on a keto diet, you can take the free Keto Digestion Course to learn how to ramp up fat in your keto diet. Seriously – don’t put this off if digestion is an issue for you. Keto won’t work if you can’t process fat or protein appropriately.
Once the beef is finished browning, set aside to cool for a few minutes.
Prepare the Cauliflower Rice
While the beef browns, cook the cauliflower rice at the same time.
This is the same delicious Mexican recipe found in The Lazy Keto Gourmet, my book filled with my favorite low carb recipes that contain zero added sweeteners. I’m so glad I thought to use it since it goes perfectly with this low carb keto taco casserole.
To cook the rice, add coconut oil to a medium skillet. Pour enough oil to cover the bottom of the pan. Then heat over medium heat until the oil is hot. While it’s heating up, add in minced garlic and chopped onion. Then cook together until the garlic turns light brown and the onions soften. This usually takes 2-3 minutes.
Then add the cauliflower rice into the hot oil. You can either rice your own head of cauliflower or take a shortcut. Most stores sell bags of frozen riced cauliflower. It’s a convenient way to get more veggies into your keto diet, so don’t thumb your nose up at this option if you’re used to making everything from scratch. I use plenty of frozen cauliflower rice and it always makes a great meal!
Stir the rice on occasion. After it’s cooked, which usually takes around 5 minutes, mix in the chili powder, oregano, salt, and salsa. Stir to combine well. You can also add cumin into the mix, but that’s not one of the taste of tacos that’s my favorite – so I tend to skip it.
Combine the Taco Bake
It’s time to combine this delicious Mexican casserole once the beef is drained and slightly cooled.
Pour the cauliflower mixture over the bottom of the greased casserole dish. Then flatten it with a spatula so it covers the bottom of the dish. Next pour the meat mixture on top in a single layer. Sprinkle the top of the casserole with cheddar cheese. If you prefer different taco flavors for your keto taco casserole, try a mixture of shredded cheese – like Monterey jack and pepper jack.
This recipe tastes great with lots of cheese, so go with whichever mixture is your favorite.
Then add a few of your favorite taco toppings on top of the cheese. These can include chopped green onion, green bell peppers, red peppers, jalapeno pepper, or even black olives.
Next, place the low carb taco casserole in the oven until the cheese melts. This should take around 10 minutes.
Finally, when you’re ready to serve, top with additional fresh toppings like sour cream or fresh salsa.
