Method
 

  1. Step 1: Prepare Chicken & Marinade. In a small bowl, whisk together 2 tbsp olive oil, 2 tbsp lime juice, lime zest from 1 lime, 1 tsp chili powder, 1 tsp brown sugar, ¾ tsp salt, ½ tsp ground cumin, ½ tsp smoked paprika, ½ tsp onion powder, ½ tsp garlic powder, ⅛-½ tsp chipotle chili powder (if using), and ¼ tsp pepper. Pound chicken breasts to an even ¾-inch thickness, then rub this mixture evenly all over them. Marinate the chicken at room temperature for about 30 minutes, or refrigerate for up to 8 hours (if refrigerating, bring to room temperature for 15-20 minutes before cooking).
  2. Step 2: Prepare Avocado Salsa (Partially). In a large bowl, combine the quartered cherry tomatoes (or chopped Roma tomatoes), fresh sweet corn (from 1 ear), ⅓ cup finely chopped red onion, ½ chopped red bell pepper, 1 diced jalapeño pepper (with seeds separated), 2 tbsp finely chopped cilantro, 1 minced garlic clove, 2 tbsp lime juice, ¼ tsp ground cumin, ¼ tsp salt, and ⅛ tsp pepper. Stir well. Cover the bowl with plastic wrap and chill in the fridge for at least 30 minutes, or up to 24 hours.
  3. Step 3: Cook Chicken (Stovetop or Grill). If using a stovetop, heat an indoor grill pan or sturdy skillet (greased) over medium-high heat until sizzling. Carefully add the chicken to the hot pan and cook, undisturbed, for 3–5 minutes until a beautiful golden-brown sear forms. Flip the chicken, cover the pan (if you have a lid), reduce the heat to medium, and cook for approximately 5–7 more minutes, or until the internal temperature reaches 165°F in the thickest part. If grilling, preheat a greased grill to medium heat (375°–450°F), and grill the marinated chicken for 5–7 minutes per side until the internal temperature reaches 165°F.
  4. Step 4: Rest Chicken. Transfer the cooked chicken from the pan or grill to a cutting board and let it rest for 5 minutes before slicing. Optionally, squeeze a little fresh lime juice over the top.
  5. Step 5: Finish Salsa & Serve. Right before you're ready to eat, gently fold the 2 chopped medium avocados into the chilled salsa mixture. Taste and adjust the seasoning as needed. If you desire extra heat, stir in some of the separated jalapeño seeds. Serve your perfectly sliced Fiesta Lime Chicken generously topped with the fresh Avocado Salsa immediately.

Notes

Substitutions & Additions: This recipe is very flexible. The rub works well on chicken thighs or pork tenderloin. For a quicker option, use pre-cooked rotisserie chicken tossed with the rub. Adjust spice levels by increasing or decreasing chipotle chili powder and jalapeño seeds. If fresh corn or cherry tomatoes are unavailable, use thawed frozen corn, canned corn (drained), or regular Roma tomatoes. Add black beans to the salsa for extra protein. This dish is also fantastic in tacos, burritos, over rice, on a green salad, or the salsa can be served as a dip with tortilla chips. A dollop of sour cream or Greek yogurt (thinned with lime juice) can be a lovely creamy addition.
Tips for Success: Pound your chicken breasts to an even ¾-inch thickness to ensure even cooking and prevent drying out. Don't skimp on the marinade time—even 30 minutes makes a difference, but a few hours in the fridge truly enhances the flavors. Always get your cooking surface hot before adding the chicken to create a beautiful sear and prevent sticking. Avoid overcooking chicken breasts; use a meat thermometer to ensure they reach 165°F and then remove them promptly. Resting the chicken is crucial for juicy results. While some substitutions are fine, fresh corn and ripe avocados make this salsa sing. You can prepare and combine all salsa ingredients (except avocado) hours or even a day in advance, adding the avocado just before serving to prevent browning.
How to Store: Store cooked chicken in an airtight container in the refrigerator for up to 3-4 days. It reheats well in the microwave or a skillet with a splash of water or broth to maintain moisture. Avocado salsa is best enjoyed fresh. Once avocado is added, it tends to brown due to oxidation. If you have leftover salsa with avocado, store it in an airtight container with plastic wrap pressed directly onto the surface to minimize air exposure for up to 1-2 days. The flavor will still be good, but the color might change. If you anticipate leftovers, only add avocado to the portion you plan to eat immediately.
