How to Make Easy Zesty Lemon Dijon Chicken Thighs with Sweet Caramelized Onions for a Flavorful Dinner!

1. In a large bowl, whisk together dijon mustard, lemon juice, lemon zest, garlic powder, dried thyme, 1 tablespoon olive oil, salt, and pepper to taste.
2. Add the chicken thighs to the marinade and toss to coat evenly. Let them marinate at room temperature for 10 minutes while you prepare the onions.
3. Heat 1 tablespoon olive oil and butter in a large skillet over medium-low heat. Add the sliced onions and sprinkle with sugar and a pinch of salt. Cook slowly, stirring occasionally, for about 20 minutes until soft, golden, and caramelized. Remove onions from the skillet and set aside.
4. Increase heat to medium-high and place the marinated chicken thighs skin-side down in the same skillet. Cook for 6-7 minutes without moving until the skin is crisp and golden brown.
5. Flip the chicken thighs and reduce heat to medium. Cover the skillet and cook for another 10-12 minutes until the internal temperature reaches 165°F and the chicken is cooked through.
6. Return the caramelized onions to the skillet, spooning them over the chicken to warm through for 2 minutes.
7. Remove from heat and garnish with fresh parsley before serving. Serve with your favorite sides, like roasted vegetables or rice.

Tips for the Best Results

• Use bone-in, skin-on thighs for maximum flavor and juicy texture.
• Don’t rush caramelizing onions—low and slow is key for sweetness.
• Pat chicken skin dry before cooking to get it nice and crispy.
• Let the chicken rest for a few minutes after cooking to retain juices.
• Adjust lemon zest and juice based on your preference for tanginess.

Storage and Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually meld beautifully overnight, making it great for next-day meals.

To reheat, warm gently in a skillet over medium-low heat or in the oven at 350°F until heated through. Avoid microwaving if possible to keep the chicken skin crispy.

Frequently Asked Questions

Can I use boneless chicken thighs instead?

What are good side dishes to serve with this chicken?
