Prep the chicken: Pat the chicken dry and season all over with 1 teaspoon salt, 1/2 teaspoon black pepper, oregano, thyme, and smoked paprika.
This builds flavor from the start.
Layer the aromatics: Add sliced onion and minced garlic to the bottom of the crockpot. Drizzle with olive oil. These create a flavorful bed that prevents sticking.
Add the chicken: Place the seasoned thighs on top of the onions in an even layer.
No need to sear, though you can quickly brown them in a skillet for extra depth if you have time.
Top with veggies and briny bits: Scatter the tomatoes, olives, capers, roasted red peppers, and artichokes over the chicken.
Liquids and lemon: Pour in the chicken broth and stir in the lemon zest and juice. Add red pepper flakes if you want a little kick.
Slow cook: Cover and cook on Low for 4–5 hours or High for 2.5–3 hours, until the chicken is tender and reaches 165°F internally. Thighs stay juicy even if they go a little over.
Finish and taste: Stir gently, then fold in fresh parsley.
Taste and adjust seasoning—add a pinch of salt, an extra squeeze of lemon, or a drizzle of olive oil if needed.
Serve: Spoon the chicken and vegetables over couscous or rice, or pair with crusty bread. Top with crumbled feta for a creamy, tangy finish.
