Rosemary Mustard Grilled Chicken or Zucchini Recipe found on KalynsKitchen.com

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!

  1. I just got a rosemary tree at one of my bridal showers! I can’t wait to try some of your recipes!! I love fresh rosemary!

  2. Tanna and Ronell, I think you will really like it.

    Cassandra, Spike is a really complex blend of a lot of ingredients. You can read the ingredients in Spike Seasoning in that post and use a blend of whatever you have. I also think this would taste fine without the Spike Seasoning (that was one of my changes to the recipe.)

  3. How very funny! I was thinking I need a chicken marinade for tonight. I’ll have to be reporting back.

  4. This looks lovely, thanks. Does anyone have an idea what we could use instead of spike seasoning (because I’m not sure it can be found in Europe)
    Best wishes

  5. I will have to try this chicken with the mustard Kalyn…it sounds delicious!

  6. Kristen, you are so welcome. It was really fun!

  7. This is by far the best chicken recipe ever! Thanks for the shower Kalyn!

  8. Comments before this one were from 2006 when the recipe first appeared on the blog. (It’s fun seeing that some of those commenters are still blogging!)

  9. I made this the other day and it was great. Thanks!

  10. this looks fantastic, can’t wait to try it!!

  11. Wow Kalyn!

    This looks and sounds delicious! Thanks for the recipe. I will definitely be trying this one!

  12. Mmmm, I love chicken and I love zucchini. I must definitely try this out.

  13. My favorite combinations! I use this kind of marinade on veal chops as well.

    Not a bad way to get through the first Phase of South Beach Diet.

    Thanks for sharing.

  14. Ooh, baby! I love this flavor combination – elegant, fresh, earthy – all at once.

  15. that’s it, you’re cooking my chicken from now on. That looks so good! and what a cool event. i’ll have to check it out!

  16. My mouth is watering, my stomach rumbling…. and my dh wont eat mustard …….. *SIGHS!* I guess I will have to fix it for me and not share a single morsel!

    If you get you stevia plants — mix three parts mint with one part stevia and steep as you usually would.. (I made a HUGE kettle of tea tonite — mixed chocolate mint and peppermint along with some stevia I found hidden in a baggy) Sweet with out the aftertaste of regular sugar or artificial stuff (which btw I avoid at all costs) and it was delish. I have 3 quarts chilling in my fridge as we speak. (told ya I made a bunch).

    Have a great week!

  17. Yum yum yum! I love rosemary with chicken & yours looks divine.

  18. I have a marinade that’s very similar to this, mine’s got less oil, more garlic and lemon, and easily 5 times that much fresh rosemary! It’s a great combination of flavors and aromas. I made some just the other night and found myself wishing for fresh ears of corn to smear it on. I’ll have to try zucchini next year. (You know it was mean linking to this just as it turns to fall for real!)

    I have huge rosemary bushes so I often have woody branches to toss on the fire just before putting the chicken–rosemary smoked food. Yum.

  19. Kalyn,
    Wow!! this is the first time I’ve looked at your blog–there are some great recipes here…I’m going to look each day for my next dinner idea. Thanks for letting me know about your blog!

  20. I’m having fun reading recipes from your kitchen. I’m excited to try more of them.
