Pat the chicken breast completely dry with paper towels to ensure a crispy sear.
Season both sides of the chicken evenly with sea salt, black pepper, dried thyme, and dried rosemary.
Heat half of the olive oil in a large stainless steel or cast iron skillet over medium-high heat.
Place the chicken in the skillet and cook for 6 to 7 minutes per side, or until the internal temperature reaches 165°F and the exterior is golden brown.
Remove the chicken from the pan and let it rest on a cutting board for 5 minutes.
In the same skillet, add the remaining olive oil and the minced garlic, sautéing for 30 seconds until fragrant.
Add the chopped kale and a small splash of water to the pan, tossing frequently until the leaves are tender and bright green.
Stir the lemon juice and lemon zest into the kale, then remove from heat.
Slice the rested chicken into strips and serve immediately over the warm sautéed kale.
