Shrimp tacos are a favorite among seafood lovers, but if you’re following a keto diet, you may be wondering whether they fit your low-carb lifestyle. While traditional shrimp tacos contain high-carb ingredients like corn tortillas and sweet sauces, you can easily make them keto-friendly with the right ingredient swaps.

A keto diet is centered around low-carb, high-fat meals that help maintain ketosis—a metabolic state where your body burns fat for energy instead of carbs. According to Healthline, staying under 50g of net carbs per day is key for ketosis. Since shrimp is naturally low in carbs and high in protein, it’s an excellent choice for keto meals. However, tortillas, sauces, and toppings can quickly add up in carbs.
Luckily, Diet Doctor suggests that lettuce wraps, cheese shells, or almond flour tortillas are excellent keto substitutes. Let’s explore how to modify shrimp tacos for a completely keto-friendly meal!
Nutritional Breakdown: Are Traditional Shrimp Tacos Keto-Friendly?
When following a keto diet, one of the biggest concerns is keeping carbohydrate intake low to maintain ketosis. While shrimp itself is naturally low in carbs and high in protein, the way shrimp tacos are traditionally prepared can significantly increase the carb count per serving.
On average, a traditional shrimp taco can range anywhere from 16g to 85g of carbohydrates per serving, depending on the ingredients used. Let’s break down the high-carb culprits and explore keto-friendly alternatives.
🔴 High-Carb Ingredients in Regular Shrimp Tacos
Many classic taco components are high in carbohydrates, making them unsuitable for a keto diet. Here’s how much they contribute to the total carb count:
- Corn tortillas – 12-20g carbs per tortilla
- While corn tortillas are a staple in Mexican cuisine, they are made from masa harina (corn flour), which is high in carbohydrates. A single small corn tortilla can contain 12-20g of net carbs, making it challenging to fit into a keto meal plan.
- Flour tortillas – 20-30g carbs per tortilla
- Even higher in carbs than corn tortillas, flour tortillas are made from refined wheat flour, which is rapidly digested and can cause blood sugar spikes. A single medium flour tortilla contains 20-30g of net carbs, nearly exceeding the daily carb limit for strict keto followers.
- Sweetened sauces (BBQ, teriyaki, honey-lime, or store-bought dressings) – 5-15g carbs per serving
- Many popular taco sauces contain hidden sugars, which can quickly add up in carbs. Even a small drizzle of BBQ, teriyaki, or honey-lime sauce can contain 5-15g of net carbs, depending on the ingredients and portion size.
- Store-bought coleslaw (often contains added sugar) – 5-10g carbs per serving
- Pre-made coleslaw mixes often include sugar-laden dressings, making them a sneaky source of carbohydrates. A single serving of store-bought coleslaw can have 5-10g of net carbs, which can be avoided by making your own keto-friendly slaw at home.
✅ Keto-Friendly Shrimp Taco Ingredients
To keep shrimp tacos keto-approved, you need to swap high-carb ingredients for low-carb, high-fat alternatives. Here are the best substitutes:
- Lettuce wraps or cheese shells – 0-2g carbs
- Instead of using carb-heavy tortillas, opt for lettuce wraps (such as romaine or butter lettuce) or cheese shells (baked cheese crisps formed into taco shells). These options keep your taco crispy and satisfying without the extra carbs.
- Homemade slaw (without sugar) – 2-3g carbs
- A simple slaw made with shredded cabbage, mayonnaise, apple cider vinegar, and seasonings keeps it low in carbs while still adding crunch and freshness to your tacos.
- Avocado, sour cream, and cheese – Keto-approved toppings
- Avocado provides healthy fats and fiber, making it an excellent keto-friendly topping.
- Sour cream adds richness while containing zero carbs.
- Shredded cheese (cheddar, cotija, or Monterey Jack) is also carb-free and enhances the texture and flavor.
- Homemade spice blends – Avoids hidden sugars in pre-mixed seasonings
- Many store-bought taco seasonings contain hidden sugars and starches, which can increase the carb count.
- A simple homemade blend of chili powder, cumin, paprika, garlic powder, and salt keeps your shrimp tacos flavorful without unwanted carbs.
Why These Keto Swaps Matter
By making these ingredient swaps, you can significantly reduce the carb count of your shrimp tacos without sacrificing flavor. A traditional shrimp taco with a corn or flour tortilla, store-bought slaw, and sweetened sauces could easily exceed 40g of carbs per taco. Meanwhile, a keto shrimp taco with cheese shells, homemade slaw, and keto-friendly toppings can contain less than 5g of carbs per taco—making it a perfect low-carb meal while staying in ketosis.
Next time you’re craving tacos, ditch the high-carb options and enjoy a flavorful, keto-friendly version instead! 🌮🔥
