Xanthan Gum Free Lemon Garlic Chicken Fajita Lettuce Wraps

Bright, citrusy, and packed with smoky spice, these lettuce wraps deliver all the sizzle of a classic fajita night without a single thickener or stabilizer in sight. Xanthan gum has a way of sneaking into spice blends, marinades, and packaged seasonings, but this recipe builds every layer of flavor from scratch — fresh lemon juice, lemon zest, smoked paprika, cumin, and garlic-infused olive oil do all the heavy lifting. The chicken gets a 20-minute marinade that drives those bold flavors deep into every strip before they hit a screaming-hot skillet and develop that gorgeous, lightly charred edge. Colorful bell peppers and zucchini cook alongside until tender and caramelized, adding sweetness and texture to every bite. Butter lettuce leaves stand in for tortillas beautifully — they're cool and crisp against the warm, spiced filling, and naturally free of any additives. Creamy avocado slices and a shower of fresh cilantro finish each cup with richness and brightness, while a squeeze of lemon wedge right before eating ties the whole thing together. It's the kind of weeknight dinner that feels festive enough for company but comes together with minimal fuss.
