Grilled chicken is a great summertime dinner. Especially when you marinade in a lemon-rosemary mixture and serve with leeks.
Jump to RecipeThe first time we had a leek was when it came in one of our Bountiful Baskets. I wasn’t even sure what it was at first or how to use it. After that, we realized we liked the taste and wanted to try a few other recipes with them.
Since we are getting close to the summer months, it’s time to start grilling. Onions are grilled all the time to go on hamburgers and similar foods. Since a leek is part of the onion family, we figured it would work on the grill, too. But, it needed a bit of flavor, so we added some garlic butter to the leek while it was cooking.
And a leek wouldn’t make a complete meal, so we added some chicken with a rosemary marinade to the grill. Overall, it made a delicious meal. Well, at least Justin and I thought so. They boys weren’t sure about the leek, but they devoured the grilled chicken.

Grilled Chicken with Leeks and Rosemary Step by Step
Ingredients
- 1 tbsp lemon zest
- 1 lemon, juiced
- 2 tsp rosemary
- ½ tsp salt
- ¼ tsp pepper
- 2 tbsp olive oil
- 2 chicken breasts, boneless, skinless
- 1 large leek, trimmed and halved
- 1 tbsp butter, shredded
- ½ tsp garlic, minced
- 1 lemon, halved
Preparation
Preheat the grill to medium-high, about 450F. Combine the lemon zest, lemon juice, rosemary, salt, pepper, and 1 tbsp of olive oil in a large stainless steel bowl.

Add the chicken to the bowl and turn to coat with the marinade.

Brush the leeks with the remaining olive oil and place the leeks, cut side down, on the grill.

Cook for about 6-7 minutes.

Take the leeks off the grill and place them on a large sheet of aluminum foil. Sprinkle the leek with the shredded butter and minced garlic.

Fold the foil over to create a foil packet. Place the foil packet on the grill along with the chicken breast and lemon halves cut side down.

Grill until the chicken is cooked, about 5-7 minutes, turning at least once. Serve by squeezing the lemon over the chicken and leeks and garnish with more rosemary.

Grilled Chicken with Leeks and Rosemary Leftovers
Leftover chicken can be stored in the refrigerator in an airtight container. It should last for up to 3 days. To reheat, place in a microwave or in the oven at 350F until warmed through. The leek can be stored and reheated the same way as the chicken.

Leek and Rosemary FAQs
A leek is a green vegetable in the onion family.
You want to cut off the top dark green parts of the leaves as well as the bottom white part. When cooking with a leek, you typically want to use the light green center of the vegetable. The tops and bottom can be used in soups, but is bitter and tough when it is eaten on its own.
If you can, I always like to use fresh. But, that also means purchasing within a day or two of cooking to use before it gets wilted. I use both fresh and dried in my recipes. Fresh will often have a slightly better taste, but dried works just as well.
