Who doesn’t love a one-pot meal?

This one-pot mustard molasses chicken recipe is easy to prepare, super flavourful and so satisfying. I cook it in the Instant Pot electric pressure cooker but you can cook it in the oven too. Instructions for both methods are below.

Serve this chicken with roasted broccoli and steamed rice. (To roast broccoli, chop two bunches into florets, toss them on a baking sheet and drizzle with 1-2 Tbsp. olive oil and a sprinkling of salt and pepper. Roast at 375 F for about 30 minutes, until tender.)

One-pot mustard molasses chicken is very versatile and is open to creative adaptations. I have used salsa in place of tomato sauce/paste, I have added a little harissa paste to the liquid mixture and from time to time I use way more garlic than called for.

The cooking time posted for the recipe includes the time it takes your Instant Pot to come to pressure.

One-Pot Mustard Molasses Chicken Recipe


  • ½ onion, chopped
  • 1 bay leaf
  • 6 boneless, skinless chicken thighs
  • 2 Tbsp. Dijon mustard
  • 2 Tbsp. cider vinegar
  • 1/3 cup molasses
  • ¼ cup tomato sauce or 2 Tbsp. tomato paste
  • 1 tsp. dried thyme or oregano
  • 1 Tbsp. Worcestershire sauce
  • ¼ cup water, broth or leftover coffee
  • 2 cloves garlic, minced


Instant Pot version:

Sprinkle onions in your Instant Pot, toss in the bay leaf and lay the chicken on top.

Whisk together remaining ingredients and pour over chicken. Secure lid of pot, turn steam valve to close and set your pot to cook for 10 minutes.

When the 10 minutes of cooking time is complete, carefully open steam valve and when steam has completely released remove lid and serve.

Serve extra sauce alongside.

Oven version:

Sprinkle onions in a shallow baking dish with a tight fitting lid and top with chicken. Whisk together remaining ingredients and pour over chicken.

Cover and bake at 350 F for 30-45 min or until chicken is cooked through.* Remove the lid for the final 15 minutes of cooking. Serve with sauce spooned over.

*Cooking time will depend on size of thighs.

    Hi Bridget:

    Just wondering if I could use Bay Leaf or savoury in this recipe instead of thyme or oregano?

    Your recipes are always a treat and a ‘walk down memory lane’. Thanks so much.


    1. Bridget Oland says:

      Hi Jane, Yes, you could change up the seasoning. I think savoury would be a nice addition. Or you could omit the herbs and add a little spice of some sort.

  2. Elizabeth Whelan says:

    Love trying out your recipes and always get a good response from my family.

  3. Jean Martel says:

    I tried to print the recipe for the chicken thighs and wondered why it needed 3 pages, it was simply because it printed 3 and a half pages of ads but not the proper recipe for the chicken. I am sorry but I don’t think I will try to print any more of your recipes.

    1. Bridget Oland says:

      Hi Jean, I’m so sorry about the printing problem. the printing plug-in on this website can be wonky.

    2. Brenda Andrews says:

      If you choose the orange + sign it takes you to a printer friendly, one page only version of the recipe.

  4. Edie Hippern says:

    After reading the recipe for the Instant Pot my first thought is this will burn. Liquid is required in order to bring the pressure cooker up to pressure. You will have burnt onions on bottom and there is simply not enough liquid. Did anyone read how to use an Instant Pot (trademark name) or other electronic pressure cooker? Did anyone test this recipe? Not willing to waste the food on this. Probably works in oven or slow cooker and sounds delicious.

    1. Bridget Oland says:

      Hi Edie, I make this recipe every week and it is always delicious. The water, vinegar, molasses, Worcestershire and tomato sauce provide ample liquid for the pressure cooker. As well, the chicken releases liquid. No worries — the onions won’t burn.

  5. Wendy Jackson says:

    Loved the molasses mustard chicken. I made it in a skillet on top of stove. Served it with barley/ rice combo

    1. Bridget Oland says:

      Hi Wendy, Cooking the chicken stove top is a great idea. Thanks for the suggestion.

  6. Antje MacEachern says:

    This recipe sounds yummy would like to make it just a question re the garlic, leave the cloves alone or crush them?
    thank you

    1. Bridget Oland says:

      Hi Antje, Garlic should be chopped or crushed but sometimes I just toss them in unpeeled.

  7. Anne Gallant says:

    When you say that the recipe time for the instant pot includes the time it takes to reach pressure does that mean you’d turn it to about 7 minutes?

    1. Bridget Oland says:

      Hi Anne, You set the timer for 10 minutes and then do a quick release of pressure.
