Ingredients
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.
For the Chicken
- 8 boneless, skinless chicken breasts
For the Marinade
- 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 (or 3–4 T minced fresh rosemary)
- 1 tsp. coarse ground black pepper
- 1 T Spike Seasoning (optional)
- 1 tsp. celery seed (optional)
For Garnish
- 2 tablespoons fresh parsley, finely chopped

How to Make Rosemary Mustard Grilled Chicken
Step 1: Prepare the Rosemary
If you have ground rosemary, use a slightly smaller amount. To crumble dried rosemary, put it into a small Ziploc bag and crush it with a meat mallet or something heavy until it’s broken up. If using fresh rosemary, ensure it’s very finely minced.
Step 2: Mix the Marinade
Combine all marinade ingredients in a mixing bowl. Whisk until well blended.
Step 3: Prepare the Chicken
Trim any fat from the chicken breasts. Make small slits across each piece to help them cook evenly; be careful not to cut too deeply.
Step 4: Marinate the Chicken
Place the chicken in a large Ziploc bag with the marinade. Seal the bag and let it marinate in the refrigerator for at least 6 hours or overnight for best results.
Step 5: Get Ready to Grill
Take the chicken out of the fridge and allow it to come to room temperature before grilling. Preheat your grill to medium-high heat after cleaning it thoroughly and applying oil or grilling spray.
Step 6: Grill the Chicken
Lay chicken on the preheated grill at an angle. Cook for 3-4 minutes until you see grill marks, then rotate to create criss-cross marks and cook for another 3-4 minutes.
Step 7: Check Doneness
Turn over each piece of chicken. Cook until firm but not hard to touch. The cooking time will vary based on thickness; use an instant-read meat thermometer to check if it has reached an internal temperature of 165°F.

- Use Room Temperature Chicken – Allowing chicken to reach room temperature before grilling ensures even cooking.
- Preheat Your Grill Properly – A hot grill creates those beautiful sear marks and locks in juices. Aim for medium-high heat.
- Monitor Cooking Time – Use an instant-read thermometer; chicken should reach 165°F for safe consumption.

Common Mistakes to Avoid
When making Rosemary Mustard Grilled Chicken, it’s easy to make a few common mistakes. Here are some tips to help you avoid them.
- Using too much marinade: While marinade adds great flavor, using too much can lead to overly salty chicken. Stick to the recommended amounts for balanced taste.
- Not marinating long enough: For the best flavor, chicken should marinate for at least 6 hours. If you can, let it sit overnight for even better results.
- Skipping the slits in the chicken: Forgetting to cut small slits in the chicken can result in uneven cooking. This step helps the chicken cook thoroughly and absorb more marinade.
- Grilling on a dirty surface: Cooking on a dirty grill can cause sticking and unwanted flavors. Always clean your grill before preheating to ensure a perfect sear.
- Ignoring internal temperature: Relying solely on cooking time may lead to undercooked or overcooked chicken. Use an instant-read thermometer to check that the internal temperature reaches 165°F for safety.
