Unless you are a vegetarian, meat is a great source of healthy protein and fat. Cajun Chicken Tacos are high in potassium (~ 40% RDA of potassium) and very low in carbs. I love this super easy recipe that takes less than half an hour to prepare. You don't need any special ingredients and they're great for garden parties!

If you've never tried using lettuce instead of high-carb tortillas, you definitely have to try this recipe!

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I made, and served this, exactly to the recipe. It was delicious and just right for two people. I served this with a side of homemade guacamole! Yum yum. Thank you, Martina...another hit!

Thank you for your lovely feedback!

What would be the macros if I don't use lettuce.  Prefer to mix it with spinach or cauliflower if I have it around

The macros would be almost the same. The only thing that lettuce does is that it adds carbs and fibre. So that would be about 7.5 g total carbs and ~ 6 g net carbs.

I am sorry if I sound stupid, but how do you get the servings?  How many of these lettuce tacos is a serving?

Hi Sophie, I just divided the whole batch into 2 servings - you can have as many lettuce leaves as you like - it won't make a difference as they are very low in carbs and calories. Hope this helps!

Where this carbs are coming from ?

Hi Zrinka, most carbs are from the vegetables and cream and some from the spices.

Made the Cajun Chicken Tacos tonight for myself and a friend and I have to say, BEST CHICKEN DISH I have had in a long time. I was wondering if the amount of spices would be enough for the chicken. I let the chicken sit in the spices (after mixing it well) while I cooked the onions, and I have to say it was spot on! Definitely making this dish again and again! I also made the keto tortillas to go with it and they were great 😊 Kitchen Vixxen

Thank you so much Marilee!! 😊

Yummmmmy! Excited to make this! Do you eat 1 serving of this for the dinner of your 3 meals on day 3 of your clean eating plan? Seems as though just this one serving with nothin else would fill me enough, especially with no snack between lunch & dinner. Thanks! 😊

Thank you Trish! That's totally up to you. You can have as many meals as you need, it's all about satiety and not. I mostly eat twice a day (servings such as this meal) and sometimes have 1-2 small snacks in between. Hope this helps! 😊

Lovely recipe, so summery! I love the idea of using lettuce instead of tortilla.

Thank you! It's my favourite recipe - so quick and yummy 😊
