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.
