This three-ingredient grilled rosemary buttermilk chicken recipe provides unbelievable flavor and tenderness to every day chicken breasts.

One of my favorite ways to prepare and grill chicken, this three-ingredient recipe provides unbelievable flavor and delicious tenderness to every day boneless, skinless chicken breasts.

My Aunt Marilyn sent me the recipe eons ago and I’ve been thankful ever since.

And lazy, too. I mean, what’s a girl to do when dinner only requires three ingredients? Sit around and eat bon-bons, that’s what.

Oh. Right. Except that girl must live somewhere else and not be the blessed mother of five rugrats who refuse to let their mother sit and eat bon-bons. Even if dinner only requires three ingredients.

Make it. And eat some bon-bons in my honor, while you are at it.

FAQs for Grilled Rosemary Buttermilk Chicken

Can I use dried rosemary instead of fresh?

I’d definitely say the fresh rosemary makes this dish because the flavor infuses the chicken more than dried would.

What exactly is a sprig of rosemary?

A sprig is one little branch and all the leaves.

What kind of buttermilk do you use?

I always use regular lowfat buttermilk.

Grilled Rosemary Buttermilk Chicken

4.75 stars (4 ratings)


  • 4 boneless skinless chicken breasts
  • 1 quart buttermilk (see note)
  • 5-6 sprigs fresh rosemary


  • Place the chicken breasts in a large ziploc plastic bag. Pour in the buttermilk to cover the chicken. Add the rosemary sprigs. Seal the bag and refrigerate overnight, about 8-10 hours.
  • Preheat a grill to medium-high heat. With tongs, take out each chicken breast one by one, shaking off excess buttermilk and removing the rosemary sprigs.
  • Grill for 4-6 minutes per side, until the chicken is cooked through but still moist. Tent with foil for about 5-10 minutes before slicing and serving.

Quantity: this recipe is so flexible and easy you can double and triple to your heart’s delight. The idea is basic – just add enough buttermilk to cover the chicken and throw in as much rosemary as your soul can take. I like a lot of rosemary flavor. Use what you like.
