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. Can you marinate the zucchini and the chicken in the same marinade or should they be done separate? I figure that both will be cooked so that the bacteria is killed off. Is this true?

  2. Thanks Teresa. My family also loves this!

  3. There have been two keys to our success with the South Beach Diet….a grill and your blog of recipes. Here both are combined to make a fabulous meal that has my husband begging for more. We barely had enough left over for his lunch tomorrow! SUPER recipe!

  4. Paul, love hearing how you adapted the recipe, thanks for sharing!

  5. I followed your recipe for the marinade but cooked it in a heavy iron skillet instead of the grill. I poured in all of the extra marinade as well and cooked it through. I added a tad of water and deglazed while the chicken was still in the pan. I also added a handful of chopped onions and some fresh chopped basil. I think this was the best chicken I have ever cooked………. Thanks!!!

  6. Daria, thanks. This is a huge favorite in my family too.

  7. I tried out this recipe and it was fantastic! Thanks so much for sharing 🙂

  8. Anonymous, thanks for the nice thoughts about the blog. I can't think of any blogs that have that capability, and right now I don't know any way to make it happen.

    I'm using a bookmarking site called del.icio.us to save links of recipes I want to remember. It's easy to use, and you can make categories. Check it out and see if that might work for you.

  9. Your site has everything I need for finding new, good-for-me recipes. I'm so pleased with the new easy system for printing the recipes. If I could only save the recipes to a personal "cookbook" like I do on Allrecipes.com and other sites, I wouldn't need those other sites! Any chance of that possibility?

  10. Couldn’t get tarragon as planned, so I found myself inspired by this idea of mustard and rosemary, only I played around a bit, did it in the slowcooker (whole chicken) with applecider and some of the ingredients you list, then thickened it afterwards and finished it off with whiskey. the rosemary and mustard was a really good combo, so thanks for the inspiration!

  11. Rache, so glad to hear this worked for you. I’ve been curious about that Penzey’s Old World Seasoning.

  12. Thank you! This is one of the best chicken recipes I’ve ever made, and your technique produced the best results I’ve had with boneless skinless breasts. I was out of dijon, so I used 1/2 stone ground mustard and 1/2 Plochman’s Beer Mustard. Instead of Spike, I added some Penzey’s Old World Seasoning. We also used the marinade for grilled shrimp. They disappeared instantly!

  13. I think I found what to make for dinner tonight!

    Thanks for all the great recipes, Kalyn!

  14. This sounds wonderful Kalyn amd I’m always in the market for quick and easy things to do with chicken 🙂

  15. Karina, I never thought of that, but what a brilliant idea. If I try it, I’ll credit you for the idea!

  16. Sounds delicious! I bet this marinade would be fabulous on grilled salmon.

  17. That grilled chicken looks really good!

  18. Anonymous, you’re right.
    T = tablespoon
    tsp. = teaspoon.

  19. Im a kitchen dummy… what does T stands for? Is it tablespoon?

  20. Maria, I know you don’t eat chicken, but try this with zucchini, it’s great!
