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 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.

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)
  • Ground Rosemary (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

Can you vary the recipe if you don’t have every ingredient?

This recipe can be adjusted to your taste and what you have on hand, and it will always turn out well. Sometimes I increase the lemon juice for a more lemony tasting chicken. I’ve used dried rosemary or fresh rosemary and both are good, although if you have it I love this recipe with Ground Rosemary (affiliate link) which mixes into the marinade well. If you don’t have Spike Seasoning or celery seed, no worries; use some other kind of all-purpose spice mixture or just skip it. If your family is lukewarm on Dijon, you could use regular mustard. No matter how you make this recipe, I bet you’re going to love it!

What else can you make with the Rosemary Mustard Marinade?

The same marinade used in this recipe is also amazing on Grilled Zucchini! Check out my tips for How to Grill Zucchini if you’re not experienced at doing that.

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 Rosemary Mustard Grilled Chicken:

(Scroll down for complete printable 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) if you have one, or use a slightly smaller amount of Ground Rosemary (affiliate link) if you have that.
  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/75C.
  8. Serve hot, and wait for compliments. 
  9. Leftover Rosemary Mustard Grilled Chicken is great over a leafy green salad, or make it into a Low-Carb Chicken Salad.

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.

Ingredients

  • 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)

Instructions

For Chicken:

  1. If you have Ground Rosemary, use a slightly smaller amount of that for this recipe,. To crumble dried 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.

Notes

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.
