Ingredients
3 ½ tablespoons prepared or powdered hot mustard (such as Colman’s)
2 tablespoons soy sauce
2 tablespoons white wine vinegar or lemon juice
2 tablespoons vegetable oil, plus more for grilling
4 garlic cloves, finely grated
2-inch piece of ginger, finely grated (about 2 tablespoons)
¾ teaspoon crushed red pepper
1 teaspoon kosher salt (such as Diamond Crystal) or ½ teaspoon fine sea salt
2 pounds boneless, skinless chicken thighs
Vegetable oil, for the grill
Chopped scallions or cilantro for serving
Preparation
- Step 1
In a medium bowl, whisk together the mustard, soy sauce, vinegar, oil, garlic, ginger, red pepper and salt until combined. Add the chicken thighs and toss in the marinade to coat well. Cover and refrigerate for at least 20 minutes and up to 1 day.
- Step 2
When ready to grill, take the chicken out of the fridge. Prepare a grill: Lightly oil the grates using a paper towel dipped in vegetable oil. Heat the grill to medium-high and when hot, lay the chicken thighs over the grates and cook, covered, until lightly charred, 5 to 7 minutes. Flip the chicken thighs and cook the other side until the chicken is cooked through, 4 to 5 more minutes. Transfer to a serving plate.
- Step 3
Serve the chicken as is, or with chopped scallions or cilantro, if desired.

I let this marinate for 3 hours in the fridge, then let it come to room temp ~30 minutes and then baked at 350 degrees for 30 minutes. Perfection! I used Coleman’s dried mustard, which gave a bit of a horseradish kick.
Delicious! Zesty, tangy, juicy & immediately secured a spot in my rotation. The heat and zip imparted from the mustard, vinegar & red pepper flakes were a perfect balance that carried through grilling. Recipe was on the fringe of being a bit too salty for my taste buds (I didn't have low sodium soy), so would reduce either the marinade salt or use low sodium soy next time. Next time I'll reserve about 1/4 cup of the marinade (before adding raw chicken) to serve over plain tide. 5 stars!
I took AGame’s suggestion and reserved some of the marinade which I brushed on just before serving. So glad I did because you get more of the heat and zip from the mustard that way. This will be my go-to for grilled chicken thighs now.
Is the 3.5 T chinese mustard in powdered form or liquid form when you add it to the soy sauce, etc.?
Delicious. I used Keen's Dry Mustard (mixed 1.5T. dry mustard with 1T ice-cold water, let sit 15 mins to activate the flavor, then added 0.5T white vinegar), and marinated overnight. Also reserved 2T. of the marinade and brushed over before serving which was an excellent idea - definitely made the dish. Everyone loved it.
Made it following the recipe up until cooking. I did not grill it- but baked it. Guests loved it. Will make it again.
