Make marinade:
Combine 2½ tbsp oil, taco seasoning, cilantro, and lime juice in a small bowl; whisk until uniform.Marinate pork chops:
Put the pork chops in a shallow glass or ceramic dish or a zip-top bag. Pour the marinade over them, flipping with tongs to ensure even coating. Cover or seal and refrigerate for 2 to 18 hours. Tip: For improved searing, remove chops from the fridge 30-45 minutes before cooking to let them come to room temperature.Heat skillet:
When ready to cook, warm 1 tsp oil in a large skillet over medium-high heat. Using tongs, lift pork from marinade, allowing excess to drip off; discard leftover marinade.Sear pork chops:
Place pork chops in the hot oil and sear for 3-4 minutes per side.Finish cooking:
Cover the skillet, lower heat to low, and continue cooking for 5-6 minutes until the internal temperature hits at least 145°F (65°C).
