Low-Carb Taco Cups {21 Day Fix, Keto}

Low-Carb Taco Cups {21 Day Fix, Keto}

Welcome, taco lovers. You’re in the right place. Except today, we’re changing it up a little. Instead of traditional tacos, I’m sharing these low-carb taco cups with avocado salsa, which are both 21 Day Fix and keto-friendly. We leave the tortillas out of the recipe to lower the carbs, but don’t worry – you won’t miss them with all this flavor!

Low-Carb Taco Cups

Low-Carb Taco Cups

You know I always like to start off my recipes with some notes, and this is no exception! Be sure to read these ones because they will help you get the best taco cups possible (and also, I’ve got some ideas and recommendations for substitutions to make this work for your diet or tastes).

First of all, as you can see by the pictures, the “taco” is really just a deconstructed taco in a cup o’ cheese. You can even go so far as to remove the cheese cupes from the ramekins if you’d like, but the ramekins will help it hold its shape.

I used 3″ ramekins for this recipe. You can find the exact ones here. You can also use muffin tins if you don’t have ramekins.

Low-Carb Taco Cups

This recipe will make 6 taco cups, and the serving size is one cup per person. These are happy little appetizers and perfect for parties because they are so much fun. You could (and likely will) have more than one, but just note that the nutritional data here is for one cup.

Use quality cheese for these. We used “cheap” cheese for the ones in the pictures here. It’s fine – it will work – but the cheese doesn’t melt as nicely and has a more rubbery texture than if you use a higher quality cheese. My favorite cheese is Cabot. You’ll be fine with whatever cheese you have…but if you have an option for better cheese, take it (always choose the better cheese = a life mantra of mine).

Low-Carb Taco Cups

Low-Carb Taco Cup Ingredients (with a few notes in here!)

  • 2 c. Colby Jack cheese, finely shredded, divided (or use cheddar)

  • 1 T. chili powder
  • 1 T. ground cumin
  • 1 t. garlic powder
  • 1 t. onion powder

Avocado Salsa:

  • 1 medium avocado, diced
  • 1 small tomato, seeded and diced
  • 2 T. fresh lime juice
  • 1 T. fresh cilantro, chopped (unless you’re like me and cilantro tastes like soap, in which case, leave it off)
  • Sea salt and black pepper, to taste 

Optional, to serve:

  • 1/2 c. sour cream (or Greek yogurt if you’re on the Fix)

  • 3" ramekins or muffin tin


  • 2 c Colby Jack cheese shredded
  • 16 oz lean ground beef or turkey
  • 1/4 c water
  • 1 tbsp chili powder
  • 1 tbsp ground cumin
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp smoked paprika
  • sea salt to taste
  • black ground pepper to taste

Avocado Salsa

  • 1 avocado medium, diced
  • 1 tomato seeded and diced
  • 2 tbsp fresh lime juice
  • 1 tbsp cilantro chopped
  • sea salt to taste
  • black ground pepper to taste

Optional Toppings

  • 1/2 c sour cream


  • Preheat oven to 250°F and line a large baking sheet with a piece of
    parchment paper or a Silpat® baking mat. Set aside.
  • Divide 1½ cups of the shredded cheese into 6 piles (approximately 1/4
    cup each) on the prepared baking sheet and spread each pile into a thin
    circular layer. Place baking sheets in the pre-heated oven until the cheese is
    melted and slightly browned around the edges, around 5-6 minutes. Keep an eye on it.
  • Remove from the oven and let cool for 2-3 minutes, then gently peel off the
    cheese and press into 3” ramekins or a muffin tin to form cups. Let cool for
    several minutes before gently removing the cheese cups from the form.

    Note: If using ramekins, the taco cups can remain in the container for extra support when serving. 
  • In the meantime, add the ground beef to a large skillet over medium heat
    and cook until the beef is browned and cooked through, approximately 6-8
    minutes. Carefully drain excess grease from skillet and return to cooktop.
  • Add water and season with chili powder, ground cumin, garlic powder, onion powder,
    and smoked paprika. Season with salt and black pepper, to taste, and stir to
    combine. Simmer for 2-3 minutes or until warmed through.
  • While the beef is cooking, combine the avocado, tomato, lime juice, and
    fresh cilantro in a medium bowl. Season with salt and black pepper, to taste,
    and gently stir to combine.
  • To serve, fill the taco cheese cups with beef, avocado salsa, and
    remaining shredded cheese. Top with a dollop of sour cream, if using, and enjoy!

Get crazy with the toppings! Onions and even some iceberg lettuce, finely chopped, would go well on these low-carb taco cups! Serve with beans and rice.

With this recipe, you can move forward with your low-carb ways and still have tacos (well, almost-tacos).
