Rosemary Mustard Grilled Chicken is a recipe that makes me want to hold on to summer! And even though Very Greek Grilled Chicken is probably most pinned and viewed grilled chicken recipe on the blog, if you asked me which grilled chicken recipe I’ve personally made the most often, this Rosemary Mustard Grilled Chicken would win, hands down.

I’ve made this tasty chicken that’s marinated in lemon, olive oil, mustard, garlic, and chopped fresh rosemary for family parties, wedding showers, baby showers, dinners with friends, and even just for dinners for myself.  No doubt about it, this is my signature grilled chicken recipe, and lots of the cooks in my huge extended family make it regularly as well.

The recipe can be adjusted to your taste and what you have on hand, and it will always turn out well. When I have lots of lemons sometimes I increase the lemon juice a little for a more lemony tasting chicken. I’ve used dried rosemary or fresh rosemary and both are good. If you don’t have Spike Seasoning or celery seed, no worries; use some kind of all-purpose spice mixture or skip it entirely. If your family is lukewarm on Dijon, you could use regular mustard. And the tasty marinade is also great on zucchini if you like the sound of that! No matter how you make this recipe, I bet you’re going to love it! 

What ingredients do you need for this recipe?

  • boneless, skinless chicken breasts
  • Dijon mustard, or mustard of your choice
  • fresh-squeezed lemon juice, I used my
  • extra virgin olive oil
  • Garlic Powder (affiliate link) or Minced Garlic (affiliate link)
  • crumbled dried rosemary or minced fresh rosemary
  • coarse ground black pepper
  • Spike Seasoning (affiliate link), or use any all-purpose seasoning if you don’t have spike)
  • Celery Seed (affiliate link), probably optional but good in this

What if you don’t have an outdoor grill?

I’d cook grilled chicken like this all winter long on a stove-top grill pan with ridges (affiliate link)  or on a  George Foreman Grill (affiliate link) if it wasn’t grilling season, so try that if you don’t have an outdoor grill.

How to make this recipe:

(Scroll down for complete recipe including nutritional information.)

  1. If you’re using fresh rosemary, chop it very finely. If you use dried rosemary, I would grind it in a Mortar and Pestle (affiliate link).
  2. Whisk together marinade ingredients. 
  3. Make slits going across the chicken breasts.
  4. Then put the chicken in in a plastic bag or plastic container with a snap-tight lid, add the marinade, and let it marinate in the fridge for  6 hours or more.
  5. When it’s time to grill, spray or brush the grill with oil, then preheat the grill over medium-high heat.
  6. Lay chicken on the diagonal across the grill grates and cook 3-4 minutes (until you see grill marks); then rotate and cook 3-4 minutes more to get marks going the other way.
  7. Turn chicken over and cook until it feels firm (but not hard) to the touch, or use an instant read meat thermometer (affiliate link) to test chicken until it reaches 165F.
  8. Serve hot, and wait for compliments. 
  9. If you don’t have an outdoor grill, this chicken could also be cooked in a stove-top grill pan with ridges (affiliate link) or a George Foreman Grill with good results (affiliate link).
  10. Leftover Rosemary Mustard Grilled Chicken is great over a leafy green salad, or make it into a Beat-the-Heat Chicken Salad.

Rosemary Mustard Grilled Chicken

Rosemary Mustard Grilled Chicken

Yield 8 servings
Prep Time 20 minutes
Cook Time 12 minutes
Total Time 32 minutes

This Rosemary Mustard Grilled Chicken is one of my long-time favorite grilled chicken recipes! And this tasty marinade is great on zucchini if you like the sound of that.


  • 8 boneless, skinless chicken breasts
  • 1/2 cup Dijon mustard (or mustard of your choice)
  • 1/4 cup fresh lemon juice
  • 2/3 cup good quality extra virgin olive oil
  • 2 tsp. garlic powder or minced fresh garlic
  • 2 T  crumbled dried rosemary (see below) or 3 – 4 T minced fresh rosemary
  • 1 tsp. coarse ground black pepper
  • 1 T Spike Seasoning (optional, but recommended, or use any good all-purpose seasoning if you don’t have spike)
  • 1 tsp. celery seed (optional)


For Chicken:

  1. To crumble rosemary, put the desired amount into a small ziploc bag and crush with your meat mallet or anything heavy until it is broken up and partially powdered. If you're using fresh rosemary, make sure it's very finely minced.
  2. Mix all the marinade ingredients.
  3. Trim all fat undesirable parts from chicken breasts, then make small slits going crosswise down the length of each piece of chicken. This is to help the chicken cook more evenly. Be careful not to cut too far into the chicken.
  4. Put chicken and marinade into large ziploc bag and let marinate in the refrigerator at least 6 hours or all day.
  5. When you’re ready to cook, take chicken out of the fridge and let it come to room temperature.
  6. Make sure your grill is clean and spray or brush with oil or grilling spray, then preheat grill to medium-high heat.  (Sometimes I use a paper towel dipped in olive oil to rub oil on the grill again immediately before I put the chicken on.  Try that if you have a problem with meat sticking on the grill.)
  7. Lay chicken on the preheated grill at an angle to grill grates and cook 3-4 minutes (or until you see grill marks when you lift up the edge of the chicken.)  Rotate chicken going the opposite angle to the grill grates and cook 3-4 minutes more (or until you see criss-cross marks when you lift up the edge of the chicken.)
  8. Turn chicken over and cook until chicken is firm (but not hard) to the touch.  Actual cooking time will depend on how thick the chicken breasts are and how hot your grill is.  For the most accurate way to tell when chicken reaches the safe temperature of 165F, use an instant read meat thermometer (affiliate link)to test chicken.

For Zucchini:

  1. To use this marinade for zucchini you can shorten the marinating time, although I have marinated it all day when I was going to be out and it turned out great.
  2. Cut zucchini pieces into lengthwise slices about 3/8 inch thick. This is a great use for larger zucchini that has escaped you, as long as they are not too huge.


You might get flare-ups if the marinade drips down when you put the chicken on the grill.  I spray water on them, even though some experts say not to do that. Don’t baste chicken with the reserved marinade because it contains bacteria from the raw chicken.

This recipe adapted years ago from a cookbook and I no longer remember where I saw it!

  2. My family loves this chicken recipe!  Thank you!!!!

  3. Kalyn, sorry, I should have mentioned that we only use part of the marinade on the chicken and reserve the other half for basting! We usually make a double batch so we’ll have enough!

    • Oh good! Glad to hear that. I never want to assume that people know things, but sounds like you definitely know what you’re doing!

  4. I have a very similar recipe that is also my signature chicken dish and has been in our family for at least 60 years (no kidding!). We use a few different ingredients…we use lemon pepper in place of the Spike Seasoning and use thyme instead of rosemary, omitting the celery seed.  We also use the marinade to baste the chicken as it grills so it developes a nice coating on the chicken. We also find that using plain ole yellow mustard works best, as the taste of Dijon is almost too subtle and gets lost in the grilling. Anyone not trying your recipe because they don’t like mustard is really missing out! I am definitely going to try your version and I KNOW it will be fabulous! 

    • Hi Judy,
      Fun to hear about a similar recipe that you’ve enjoyed. I think mustard + chicken + herbs is such a great combination. I hope you are reserving some marinade that hasn’t had raw chicken in for the basting, although obviously it hasn’t hurt you. But I have always heard not to baste with marinades that have been used on meat because there may be bacteria in the marinade that doesn’t get cooked long enough if it’s basted on towards the end of the cooking time.

      And now you have inspired me to try this with regular yellow mustard because I love that flavor!

  5. Has anyone tried this recipe stove top? I don’t have a grill. 

    • If you have a stovetop grill pan with ridges (or something like a George Foreman Grill) you could definitely cook it that way. I’m not sure about just cooking in a frying pan, but it may work.

  7. I was nervous to try this recipe because I’m not a mustard fan, but I am so glad I did – my husband and I were blown away by how delicious it is! This is my favorite recipe from this blog which is saying A LOT.

    Highly recommend it to everyone looking for a flavorful chicken marinade, regardless of if you like mustard or not!

  8. This has become one of my favorite recipes! I made it for Father's Day last month and it was once again a hit. Our daughter's fiance told her it was the best chicken he ever had in his life! He gets to have it again tonight. I'm making it for my husband's birthday dinner. Thanks so much for such a great recipe. I love that it's super easy for entertaining.

  9. Barb, so glad you liked it! And good to know that it can be marinated that long.

  10. Just came across this recipe. Due to circumstances beyond my control ( thunder storms at supper time) this was not marinated for 6 hrs but 3 DAYS!! It was still awesome! My mate does not like chicken much but I got a 'pretty good' from him. Will definitely try this on him again!! Maybe. Next year

  11. Kellie, I've never done it that way and I would probably keep them separate. It might be fine, but I just don't know enough to say for sure.
