Grilled sirloin steak “flaco” tacos use lettuce wraps instead of tortillas! The steak is seasoned with cumin and spices, then grilled and sliced thin, along with guacamole and pico de gallo – low-carb and super delicious!
Steak Taco Lettuce Wraps
These steak lettuce wrap tacos are also Keto, Whole30, and gluten-free. See all my lettuce wraps here, like these Turkey Taco Lettuce Wraps and Thai Chicken Peanut Lettuce Tacos.
These lettuce wrap steak tacos were inspired by tacos I recently oredered at a Tex-Mex restaurant in NYC. They were so good, I didn’t miss the tortilla so I set out to recreate them at home. They used iceburg lettuce which they cut on an angle and used several layers which I thought was smart because it was easier to hold and eat. You can of course use any lettuce you like. If you don’t have a grill, you can make the steak on a grill pan or even on a cast iron skillet. So simple and light, you can easily eat more that two if you don’t make a side. I made a Mexican Cauli-rice on the side which was enough to fill me up.
How to Make Steak Taco Lettuce Wraps
Lettuce wraps are low-carb, keto, gluten-free and low calorie, and don’t interfere with the flavors of the filling. A few tips when making lettuce wraps:
- Look for lettuce leaves that are large enough to hold the filling. I like to use iceberg lettuce for larger cups. Romaine lettuce and baby romaine are also great.
- The leaves of butter or boston lettuce are smaller, but also wonderful.
- If you prefer, you can turn this into a big chopped salad by simply serving this over a bowl over chopped lettuce.
Here’s a few more of my favorite lettuce wrap recipes:
- Asian Chicken Lettuce Wraps
- Buffalo Chicken Lettuce Wraps
- Turkey Santa FE Lettuce Wraps
- Chicken Club Lettuce Wrap Sandwich
- BLT Lettuce Wraps
- Tuna Lettuce Wrap with Avocado Dressing
- Chicken and Shrimp Larb

This was so good on a hot day! All the salads were so refreshing. I subbed cumin for coriander but otherwise followed directions. This one will be going in the regular rotation for summer. I do wish all the recipes here gave ingredient weights. I appreciate all the healthy meals that have flavor and instructions that work! Thank you
Absolutely fantastic! So fresh, so easy. Thanks Gina!
Amazing!
Great recipe! So delicious and filling. It was very easy to prepare as well. Will be making again!
Could the steak that has already been cut up and sold for stir fry be used for this recipe?
I bought everything I need so I’ll be cooking this for supper tonight.
We loved this!!!!!! Thank you!!!!! So tasty. Paired with the fiesta lime rice was perfection!!!!
This recipe delivers on great taste! The meat, guacamole, and pico were all fantastic together. My husband didn’t even miss the tortillas. I used ruffled greed leaf lettuce and it really held up nicely. Thanks!
Oh my God…
I tried this receive and my sweetheart gave me 10 stars. This was so yummy and healthy… Thx for sharing such a healthy and delicious recipe….
Love love love this and super easy
The guacomole was the best!!!!
I’m following your meal plan and have to admit I was kind of ‘meh’ about the thought of lettuce cups for dinner…but, I stuck to the plan and OMG these are AMAZING! I am a total convert! The meat is tender and super flavorful and I would like to eat the guacamole by the bowlful…so delicious and very filling! WINNER, WINNER, STEAK DINNER!
Lol glad you enjoyed it!
Can you cook meat in the slow cooker or cast iron?
Cast iron skillet.
Do you cook for the same amount of time on the cast iron? High heat 2-3 min each side?
Dinner tonight!! In a word… FANTASTIC!!! Thanks Gina!
DELICIOUS! I made it one with with steak then the next week I swapped chicken tenders for the steak. Also really yummy.
We had these for dinner tonight. They were amazing
Hi I’ve made this two times it’s amazing! I just wanted to say that instead of the pico I used your restaurant style salsa recipe and I added pickled red onions (in red wine vinegar) to the top (I omitted the onions from the guacamole). Love this site! Thank you so much!!!
We used the Mexican Spice mix from the SOUTHWEST CHICKEN SKILLET recipe (https://www.skinnytaste.com/southwest-chicken-skillet/comment-page-1/#comment-176653) and were totally blown away!!!!
Holy bananas. We love these steak lettuce tacos and make them regularly at our house. I love to add in a dollop of guac on top and to eat on the side with tortilla chips! They are an amazing summer dinner!
Made these today and they were AMAZING!!! Had always been afraid that I would miss the tortilla but it was delicious! Used romaine lettuce but is was great! Even the crunch in the lettuce made me feel I wasn’t missing a thing. My husband may even try them next time!!
Made this tonight for dinner…I actually used the left over thin cut steak from the stuffed portabella mushroom recipe and was awesome…I added jalapeno poppers as a side what a great dinner…didn’t make the cauliflower rice this time but ill try it next…Thank you for all the wonderful recipes…it has made huge positive change in our family dinners!!!!
Awesome!
Made the tacos and rice for lunch today and couldn’t believe how much food there was for so few points! Everything tasted wonderful! Thanks Gina!!
You’re welcome Anne! Glad you enjoyed it!
This is delicious, but it’s definitely NOT 4 SmartPoints. 1/4 avocado is 2-3 points depending on size, and .25 lb of steak is 5 points. That makes two tacos at least 7-8 points.
I think maybe this is because you left out the saturated fat in calculating the nutrition.
Absolutely loved this recipe – as did my fiancé! Love your low-carb recipes!
How do you get the lettuce to look like that I can never get it to look like yours. Video maybe??
Thank You Gina Looks Amazing
OOPS! Need the cauliflower rice, too! looks good!
Please include the carb count! I would love to try our recipes, but I am eating low carb and need the info!
Thanks
M
The nutritional info is always listed under the recipe. 🙂
This is so so good!
What is the serving size of the steak that goes into each taco? 2 oz each?
Yes.
hi Gina
I never saw the answer to how to make the lettuce cups? not sure if hard to describe, but you can give it a whirl for your fan club that would be awesome!!! 🙂
would like to try making this week tnx
Cut the iceberg lettuce on an angle and used several layers. 🙂
I made these last night for dinner! Very quick and healthy, I added a 1/2 teaspoon of cumin to the Pico to give it a more authentic taste. Delicious! Thank you!
I’m starting a low-carb eating plan today do you have any recommendations for special recipes or a special section for that?
If you go to the “special diets” tab on Skinnytaste, it will give you a low carb option.
Loved this – lettuce didn’t quite cooperate so we improvised
Had chicken, is made with that instead…it was all great! My husband and 13-year-old son made lettuce burritos by adding the Mexican cauliflower rice right in the lettuce wraps, and my 8-year-old had a LETTUCE TACO. Didn’t even have to suggest it. He was intrigued and tried it all on his own!
Spot on! Was so good. Next time I need to double it for leftovers. It was gone so quickly!
About the calorie count: Is it 256 cals with the guacamole or just the two taco’s?
I made this last week and the entire family went nuts over it. I think this guacamole might be the best I’ve ever had. Going to try this again tonight but with chicken. Also, no one but me likes cauliflower so I made the “rice” with broccoli and it was delicious! Thanks for the low carb options!
So happy to hear!!!
I’m SO HAPPY that you have Paleo recipes! LOVE IT!
The Smart Point calculator shows 5 points for the nutritional values you have listed.
The only accurate way to determine any recipe’s SmartPoints® value is to plug the ingredients into the recipe builder on the Weight Watchers website (Click on “My Foods,” select “Recipe,” and click “Create a recipe.”) which does not count fruits and vegetables in recipes in the calculations as they are now 0 points.
The SmartPoints® calculator isn’t meant for recipes and will often give you the wrong points (usually higher). So if you see a recipe with a SmartPoints® value that’s different from what the calculator tells you, now you know why! Test it out for yourself!
So interesting!! Thank you SO much for letting me know!!
I made this last night along with the Asian Mango Cabbage Slaw as a side dish. SO DELICIOUS!!!!
Made as written, loved the pico and guac. It came together faster than I thought especially with all the chopping. Made the pico again to serve with your blackened fish. The iceberg wraps worked great. Thank you!
Awesome
1/4 avocado =2sp
Depends on the size of the avocado!!! They come in all sizes which is why I listed the oz.
Your calculations are off. 3oz of cooked steak alone is 5 sp.
I made this yesterday. Yummy. Two lettuce leaves with fuxings 8.5 sp
4 oz of raw lean sirloin beef, trimmed of fat is 2 SP.
Wow! So delicious and so flavorful. Thanks for another great recipe.
Made these yesterday, and they were to die for! I may be choosing lettuce “taco shells” from now on because I love tacos, but the tortillas are just wasted calories.
I’ve got high blood pressure, so I substituted Morton’s Salt Substitute for the salt and found it to be a little too salty. Not sure if that’s a factor for my substitution or not. (It’s still new to me.) I’d probably cut the salt in half or more.
Glad you enjoyed it!
These tacos with the cauliflower rice were outstanding. Gina you make the best food ever! Thanks so much for sharing.

How did you cut the head of iceberg lettuce to make the shells? I’m not sure what you mean when you say the lettuce was “cut on an angle”. Thanks.
