Start by preheating your oven to 350°F. Meanwhile, in a large pan over medium heat, melt your cooking fat. Once heated, add in the chicken, skin side down. Cook for 3-4 minutes per side, or until the chicken is crispy and browned. Set the chicken aside for now.
¼ cup of cooking fat, 8 chicken thighs
Using the same skillet, add in your onions and cook for 5 minutes. Remember to stir regularly and scrape the chicken bits off the bottom of the pan. Add in your garlic, cook for a minute until it's aromatic, then season with salt and black pepper.
3 cups onion, Sea salt and freshly ground black pepper to taste, 30 cloves garlic
Add your chicken stock, thyme, and lemon juice to the pan, then stir everything together. Place your chicken thighs back into the pan, skin side up, and bring it to a simmer. Once ready, place the pan, covered, in the oven for 20 minutes.
½ cup lemon juice, 1 ½ cups chicken stock, A bunch of picked thyme leaves
After the 20 minutes have passed, remove the lid and add in the olives and lemon slices. Continue baking everything uncovered for another 15 to 20 minutes.
½ lb black olives, 2 extra lemons
Finally, serve your chicken thighs with some of the sauce, onions, and olives. Enjoy your delicious meal!
