In a large bowl, whisk together the Dijon mustard, honey, olive oil, minced garlic, salt, pepper, and chopped parsley until well combined. Add the chicken thighs and toss until they're fully coated. Cover the bowl with plastic wrap and pop it in the fridge until you're ready to use it.

Add the quartered onion, carrot pieces, and potato chunks to a large Dutch oven or oven-safe skillet. Drizzle with olive oil, sprinkle with chopped thyme, season with salt and pepper, and toss everything together until the veggies are well coated.

Cover your skillet with a lid or aluminum foil and transfer to the preheated oven. Let the vegetables bake for about 20 minutes to get them started cooking.

Remove the skillet from the oven and arrange the marinated chicken thighs in a single layer on top of the partially cooked vegetables. If there's any marinade left in the bowl, brush it generously over the chicken.

Return the skillet to the oven, uncovered this time, and bake for another 30-45 minutes until the chicken is cooked through (internal temperature of 165°F) and the vegetables are tender when pierced with a fork.
