It's easy to make these 30-minute keto tacos with crispy cheddar cheese shells that you quickly "bake" in the microwave. Filled with all the traditional goodies, these tacos are just as good as traditional ones!

There's no need to give up tacos on the low-carb diet! One excellent alternative is this taco salad. Another is these keto tacos, which are incredibly good and so easy to make. You can make these tacos as usual with well-seasoned ground beef and your favorite toppings, and simply replace the tortilla shells with crispy cheddar shells.
Ingredients
You'll only need a few simple ingredients to make these tacos. The exact measurements are listed in the recipe card below. Here's an overview of what you'll need:
- Shredded cheddar: You can shred it yourself or buy it pre-shredded. I like to use extra-sharp cheddar because it's so flavorful.
- Lean ground beef: I use 85% lean ground beef.
- Taco seasoning: To make life easier, I use a store-bought mix.
- Toppings: Whatever you like! I use salsa and sour cream.
Variations
- You can use ground chicken or turkey instead of ground beef, but you should use dark meat. White meat is too dry.
- Ground pork is another tasty option that I like. It's very juicy.
- Vary the toppings you use. I typically use salsa and sour cream, but other options that I tried and liked include sliced avocado, guacamole, sliced jalapenos, and cilantro.
Instructions
Scroll down to the recipe card for detailed instructions. Here are the basic steps for making this recipe:
You start by wrapping a ruler in foil and suspending it between two glasses or mugs. You will use this contraption to shape the cheddar shells.
Form taco shells using microwaved cheddar cheese: Place shredded cheddar on a piece of parchment paper. Spread it thinly into a circle. Microwave until golden brown, about 1:30 minutes. Allow it to slightly cool but still be pliable. Gently peel it off the parchment paper and fold it over the ruler to shape it into a taco shell.
Cook the ground beef with taco seasoning: Heat a large skillet over medium-high heat. Add the ground beef. Cook, stirring to break up the meat, until the meat is no longer raw. Drain well.
Return the meat to the skillet and reduce the heat to medium. Stir in the taco seasoning and 2-4 tablespoons of water. Keep cooking for 2 more minutes.
Assemble the tacos: Divide the meat between the cheddar shells, top it with your favorite toppings, and serve.
Expert Tip
You'll want to microwave the cheddar shells until crispy but still pliable, and you should allow them to cool for no more than a couple of seconds before shaping them into tacos. If they become too crunchy, they'll break as you try to shape them.
Recipe FAQs
Yes! You simply need to replace the traditional shells, typically made with corn tortillas, with a low-carb alternative. Baked cheese shells are perfect, and this is what we use here.
The filling is identical to a traditional taco - ground beef cooked with lots of spices. The difference is in the shell you use. You use a crispy cheese shell instead of a corn tortilla shell.
Not really. You can make them an hour or so in advance, but not much more. They lose their crunch quickly. But they are so easy to make and ready so fast that I don't see it as an issue.
Serving Suggestions
As you can see in the photos, I like to top these tacos with salsa and sour cream. You can add sliced avocado or guacamole.
I don't like to sprinkle them with shredded cheddar since they already have quite a bit of cheese in the shells!
Apart from these toppings, I often serve keto tacos with an easy vegetable side, such as fresh-cut veggies, microwave broccoli, arugula salad, or cucumber tomato salad.
Storing Leftovers
The only component of this recipe that can be stored is cooked ground beef. You can keep it in the fridge, in an airtight container, for up to 3 days and reheat it in the microwave.
The assembled tacos won't keep as leftovers (they'll become soggy), and as mentioned above, the cheddar shells will lose their crispness when stored.

Keto Tacos with Crispy Cheddar Shells
Video
Ingredients
- 8 ounces cheddar - shredded; 2 cups
- 1 pound lean ground beef - 85/15
- 1 ounce taco seasoning
- Your choice of toppings
Instructions
Make the taco shells:
- Wrap a sturdy ruler in foil and suspend it between two glasses or mugs to create a tool for shaping the taco shells.
- Place ½ cup (2 ounces) of shredded cheddar on a piece of parchment paper. Spread it thinly into a 6-inch circle. Microwave on high until golden brown, about 1:30 minutes. Keep in mind that microwave ovens vary.
- Allow the cheddar to cool for no more than a couple of seconds, just until you can bear touching it. You want it to remain pliable. Gently peel it off the parchment paper and fold it over the ruler. This will shape the cheddar crisp into a taco shell.
- Repeat three more times with the remaining cheese. Place the formed cheddar shells on plates.
Cook the ground beef:
- Heat a large skillet over medium-high heat. Add the ground beef. There’s no need to add fat – the meat will release fat fairly quickly. Cook, stirring to break up the meat, until the meat is no longer raw, about 5 minutes. Drain well.
- Return the meat to the skillet and reduce the heat to medium. Stir the taco seasoning and 2-4 tablespoons of water into the meat (start with 2 and see if you need to add more). Keep cooking for 2 more minutes.
Assemble the tacos:
- Remove the skillet from the heat. Using a slotted spoon, scoop the meat up from the skillet, dividing it evenly among the cheddar shells. Add your choice of toppings (such as sour cream, guacamole, and salsa) and serve.

I imagine these are good, but I don't know anyone who has ever eaten just 1 taco, which you have listed as 1 serving (so eating just 2 would be 800 calories!). Using low-carb flour tortillas (Mission makes them, and I swear I can't tell the difference between them and regular flour tortillas) would work just as well for tacos -- and you could have more than 1! 🙂
Love your steak fajitas and Keto taco salad recipes -- I don't do Keto but that taco salad is amazing.

Hey Karen,
Glad you like the steak fajitas and Keto taco salad! Perhaps you can help other readers by reviewing those recipes.
It's been my experience that one of these ultra-rich tacos with a side of steamed microwave broccoli or a simple arugula salad is a hugely satiating and satisfying meal.
Mission Carb Balance flour tortillas contain hydrogenated soybean oil and sucralose plus several other ingredients that I don't recognize and cannot pronounce. They also contain 15 grams of fiber per tortilla, making them unsuitable for some people. I'm glad they work for you, though! You do you. ❤️
