Chicken thighs and potato gnocchi bake together on one sheet pan, the gnocchi soaking up garlicky tomato juices while goat cheese melts over the top. Scatter fresh basil over it and serve straight from the pan.
Put the chicken in a large bowl. Add the sliced onion, ¼ cup extra virgin olive oil, sliced garlic, 2 teaspoons dried oregano, 1 teaspoon kosher salt, ½-1 teaspoon crushed red pepper, and black pepper to taste. Toss the chicken around until it's evenly coated. * At this point, you can cover the seasoned chicken and refrigerate up to 1 day ahead of baking.
On a 12x15x1-inch rimmed baking sheet, spread out the gnocchi. Nestle the chicken in and around the gnocchi - make sure to scrape out and include all the olive oil and seasonings. Pour the tomatoes around the chicken and gnocchi.
Bake 20 minutes. Turn the chicken pieces over, using a pair of tongs or a spatula. Crumble the cheese evenly over the top. If you're using ricotta, spoon it over in random blobs. Return the pan to the oven and bake 5-7 more minutes, until the pan juices are bubbling and the cheese is very soft.
Roughly tear the basil leaves and scatter over the chicken. Serve and enjoy!
Make sure to use the correct size pan. Anything larger than 13x5 will mean the pan juices will evaporate, and you don't want to lose that sauce. Typical "jelly roll" pans are a perfect size. If you're doubling the recipe, use a half-sheet pan (18x13").
