Thai Steak Lettuce Cups

Steak Cups? Please, Lettuce Explain.

Sorry about the pun—we just had to. And no, we don’t mean a cup made out of steak. We mean butter lettuce leaves used to “cup” a portion of marinated, seared steak slices and then eaten taco-style. Traditionally made with spiced, ground chicken, you may have tried “Larb Gai” (sometimes called “Laab”) in a Thai restaurant before. We’ve opted for a meatier, steak-centric filling, because we’re huge steak fans, and we’re keeping the marinade ingredients super simple so that you don’t have to hunt down any unusual ingredients.

Kid-Friendly, Keto-Friendly, Weeknight Dinner Magic.

Bright, crisp veggies and ultra-savory, seared beef topped with more of that zingy marinade—and you get to eat it with your fingers?! These umami-rich, paleo / keto / gluten-free / you-name-it Thai steak lettuce wraps are a whole-family pleaser. Plus, the only actual cooking required is a quick stove-top sear for the steak, but you could even cook the marinated flank steak outside on the grill to make it that much easier.

Marinate, Marinate, Marinate.

These Thai steak lettuce cups are all about the marinade. As we’ve mentioned, we’re not calling for anything hard-to-find—no lemongrass or kaffir lime leaves. Just stir together a few easy-to-find Asian ingredients and let this marinade work its flavor-giving magic on that juicy, tenderized steak. For the dressing, you’ll need:

• Tamari or soy sauce
• Fish sauce
• A lime
• Fresh garlic, cilantro and scallions.
• Chilli paste

How to Slice Steak.

Flank steak or skirt steak are the best choices for these Thai steak lettuce cups because they offer deliciously meaty, intensely beefy flavor and are nice and lean. Because they’re lean, you run the risk of winding up with tough steak, so we’ve added the extra (easy) step of tenderizing the meat before marinating it. Both that tenderization and the marinade help to ensure juicy, flavorful, tender steak.

As for slicing the steak, always slice against the grain so that the slices of steak are tender and easy to chew—if you cut with the grain (i.e. the way the muscle fibers are aligned) you’ll wind up with tough steak pieces, no matter how thin you’ve sliced them.

All Dressed Up.

While toothsome, juicy flank or skirt steak wrapped in a crispy crunchy butter lettuce leaf is good on its own, we love to garnish our Thai steak lettuce cups with:

• Julienned (super finely sliced) carrots.
• Julienned (super finely sliced) sweet red bell peppers.
• Vibrant fresh herbs, like mint and cilantro.

Tools You’ll Need:

• A sharp knife.
• Meat tenderizer (or a rolling pin, in a pinch.)
