Place chicken thighs and potatoes in oven. Bake in a 350° oven for 45 minutes. At 45 minutes, carefully stir potatoes with spatula, check for doneness and bake spuds for 15 more minutes uncovered. Or, until done. Also, taste test your potatoes and decide if you'd like more sea salt added. I'll usually add more. Pierce your thickest piece of chicken with a knife. If the fluids run completely clear, they're baked. Pull chicken from oven and set to the side.
