Ingredients Overview (Clean, Simple & Measured Exactly)
Main Ingredients
- 1½ pounds (680 g) boneless, skinless chicken thighs or chicken breast
- 2 tablespoons olive oil, divided
- 1 medium yellow onion, thinly sliced (about 1½ cups / 150 g)
- 2 cloves garlic, minced
Dijon Marinade
- 3 tablespoons Dijon mustard
- 1 tablespoon fresh lemon juice
- 1 tablespoon olive oil
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon dried thyme (or 1 teaspoon fresh)
Light Dijon Sauce
- ¾ cup (180 ml) low-sodium chicken broth
- ¼ cup (60 g) plain Greek yogurt (2% recommended)
- 1 teaspoon honey (optional)
- 1 teaspoon Dijon mustard
The Dijon Mustard Marinade: Small Step, Big Flavor
This quick marinade is the backbone of the dish. Even 10 minutes makes a difference — something I learned after testing this recipe repeatedly. Dijon mustard acts as both flavor and tenderizer, which is why it works so well for lean chicken breast and richer thighs.
In a medium bowl, whisk together:
- 3 tablespoons Dijon mustard
- 1 tablespoon olive oil
- 1 tablespoon lemon juice
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon dried thyme
Add the chicken and toss to coat evenly. Let marinate for 10–20 minutes while you prep the onions.
How to Make Crispy Onions (Clean Eating Style)
I’ll be honest — the crispy onions were an experiment that turned into a non-negotiable. They add texture that elevates this from “healthy chicken dinner” to true comfort food.
- Heat 1 tablespoon olive oil in a large skillet over medium heat.
- Add sliced onions and a pinch of salt.
- Cook for 12–15 minutes, stirring occasionally, until golden and crisp-edged.
Remove onions from the pan and set aside. Do not clean the skillet — those browned bits matter.
Step-by-Step: 30-Minute Cooking Method
- In the same skillet, heat remaining 1 tablespoon olive oil over medium-high heat.
- Sear marinated chicken for 4–5 minutes per side until golden.
- Remove chicken and lower heat to medium.
- Add garlic and sauté for 30 seconds.
- Deglaze with ¾ cup chicken broth.
- Whisk in 1 teaspoon Dijon mustard and 1 teaspoon honey.
- Reduce heat to low and stir in Greek yogurt.
- Return chicken to pan and simmer 5–7 minutes.
- Top with crispy onions and serve.

- Breast: Lean, protein-packed, ideal for clean eating goals
Both work beautifully with this Dijon sauce.
