Ingredients You’ll Need

What I love most about this recipe is how straightforward the ingredients are, yet each plays a crucial role in building layers of flavor and texture. From the sharpness of Dijon mustard and fresh lemon juice to the rich warmth of smoked paprika and the subtle sweetness of caramelized onions, every component shines.

4 chicken thighs, bone-in or boneless: Choose your preference; bone-in offers juicier meat, boneless cooks faster.
3 tablespoons olive oil, divided: Essential for searing the chicken and caramelizing the onions to golden perfection.
2 large onions, thinly sliced: These slowly caramelize to create a luscious, sweet bed for the chicken.
3 garlic cloves, minced: Adds a fragrant depth and savory punch to the marinade.
¼ cup lemon juice, freshly squeezed: This bright acidity balances the richness and infuses a fresh zing.
2 tablespoons Dijon mustard: Brings a tangy, slightly spicy flavor that complements the lemon beautifully.
1 teaspoon smoked paprika: Offers a gentle smoky aroma that rounds out the dish.
½ teaspoon cayenne pepper: Just enough to add a subtle kick without overwhelming the palate.
1 teaspoon bouillon powder or seasoning blend: Enhances the savory notes and deepens the overall taste.
½ teaspoon salt, or to taste: Brings all flavors into balance.
1 cup chicken broth: Creates a flavorful simmering liquid that keeps the chicken tender.

How to Make Lemon Dijon Chicken Thighs with Caramelized Onions Recipe

Step 1: Prepare the Ingredients

Start by patting the chicken thighs dry with paper towels—this step is crucial for getting a beautifully browned crust later on. Then, slice your onions thinly and mince the garlic so they’re ready to go into the marinade and eventually the skillet.

Step 2: Marinate the Chicken

In a large bowl, whisk together the minced garlic, sliced onions, freshly squeezed lemon juice, Dijon mustard, smoked paprika, cayenne pepper, bouillon powder, and salt. Toss the chicken thighs in this vibrant mixture, making sure each piece gets coated well. Cover and refrigerate for at least two hours; overnight marinating really lets those flavors soak in and develop.

Step 3: Brown the Chicken

Remove the chicken from the marinade, allowing extra marinade to drip off but keep all those sliced onions and leftover marinade aside for later. Heat two tablespoons of olive oil in a large skillet over medium-high heat. Place the chicken thighs in the hot pan and sear them for 4 to 5 minutes on each side until they develop a gorgeous golden-brown color. Transfer the chicken to a plate to rest for a moment.

Step 4: Caramelize the Onions

In the same skillet, pour in the remaining tablespoon of olive oil. Add the reserved onions and any leftover marinade along with them. Lower the heat to medium and cook for about five minutes, stirring regularly. The onions will soften and begin to caramelize, turning sweet and slightly golden—a crucial flavor element of this Lemon Dijon Chicken Thighs with Caramelized Onions Recipe.

Step 5: Simmer the Chicken

Now, nestle the browned chicken thighs back into the skillet on top of the caramelized onions. Pour in the chicken broth and bring everything to a gentle simmer. Cover the pan and let it cook on medium-low heat for 15 to 20 minutes until the chicken is tender and fully cooked through.

Step 6: Adjust and Serve

Before plating, taste the sauce and tweak it if necessary with extra salt or a squeeze more lemon juice to brighten it up. Spoon plenty of those luscious onions and sauce over the chicken, and get ready to dig into one of the most flavorful meals you’ll make this season.

FAQs

Can I use skinless chicken thighs for this recipe?

Yes, skinless chicken thighs work well if you prefer less fat, though the skin helps keep the meat juicy and adds extra flavor when seared.

Is it necessary to marinate the chicken overnight?

While marinating overnight enhances the flavor, even 2 hours is sufficient to infuse the chicken with the wonderful lemon and Dijon notes.

Can I substitute another type of mustard?

Dijon mustard is ideal for its smooth texture and slightly sharp profile, but whole-grain or spicy brown mustard can also add interesting variations to the dish.

What can I use instead of chicken broth?

If you don’t have chicken broth on hand, vegetable broth or even water with a splash of soy sauce or seasoning can work as a flavorful alternative.

How spicy is this recipe?

The cayenne pepper adds just a gentle warm heat that complements the flavors without overwhelming. You can adjust the amount to your spice preference or omit it altogether for a milder taste.
