Ingredients
  

  • Chicken: 2 to 2.5 pounds boneless, skinless chicken thighs (or breasts)
  • Olive oil: Extra-virgin for the marinade and finishing
  • Lemon: Zest and juice of 1 large lemon
  • Red onion: 1 medium, thinly sliced
  • Garlic: 4–5 cloves, minced
  • Red wine vinegar: 1–2 tablespoons
  • Chicken broth: 1/2 cup (low-sodium)
  • Dried oregano: 2 teaspoons
  • Dried thyme: 1 teaspoon
  • Smoked paprika: 1 teaspoon (optional but great)
  • Bay leaf: 1
  • Kalamata olives: 1/2 cup, pitted and halved
  • Feta cheese: 1/2 cup, crumbled (for serving)
  • Fresh herbs: Parsley and/or dill, chopped
  • Salt and black pepper: To taste
  • Optional add-ins: Cherry tomatoes, artichoke hearts, capers, or baby potatoes

Method
 

  1. Prep the chicken: Pat the chicken dry and season both sides with salt and pepper. This helps lock in flavor and improves browning if you choose to sear.
  2. Make the seasoning mixture: In a small bowl, combine olive oil, lemon zest and juice, minced garlic, red wine vinegar, oregano, thyme, smoked paprika, and a pinch of salt and pepper. Stir well.
  3. Layer the base: Add the sliced red onion to the bottom of the slow cooker. Pour in the chicken broth and add the bay leaf.
  4. Optional sear: For extra flavor, quickly sear the chicken in a hot skillet with a little oil, 1–2 minutes per side, just until lightly golden. Not required, but it adds depth.
  5. Add the chicken: Place the chicken on top of the onions. Pour the seasoning mixture over the chicken, coating it evenly.
  6. Cook low and slow: Cover and cook on Low for 4–5 hours or on High for 2–3 hours, until the chicken is tender and reaches 165°F.
  7. Add olives and finish: About 20 minutes before serving, stir in the Kalamata olives. Taste the sauce and adjust salt, pepper, or lemon as needed.
  8. Serve: Top with crumbled feta and fresh parsley or dill. Spoon over rice, orzo, couscous, roasted potatoes, or tuck into warm pita with a dollop of tzatziki.
  9. Optional thickening: If you want a thicker sauce, remove the chicken and whisk 1 teaspoon cornstarch with 1 tablespoon cold water. Stir into the liquid, cover, and cook on High for 10 minutes until slightly thickened. Return chicken.
