Easy Summer chicken
There’s truly nothing simpler or more foolproof than these grilled chicken thighs! The marinade uses simple ingredients, and since chicken thighs have more fat on them than chicken breasts, they’re almost impossible to overcook. This is why I use them in so many recipes, from my oven-baked barbecue chicken to my Mediterranean chicken and orzo.
Serve these marinated grilled chicken thighs with your favorite summer salads, like Italian potato and green bean salad, tomato and mozzarella salad, or deli-style macaroni salad.
Recipe Ingredients
All ingredients for this recipe are shown in the pic below, and special notes are made in this bulleted list to assist you.

- Chicken. I’m using boneless skinless chicken thighs, but you can use bone-in thighs as well. And yes, you can use the marinade on chicken breasts, but be sure not to overcook them as they can dry out. Chicken breasts should be cooked to 160° and removed immediately.
- Marinade/Dressing. I’m using a combination of olive oil and neutral oil, red wine vinegar, Pecorino Romano, Dijon mustard, garlic, fresh parsley, dried oregano, and crushed hot red pepper flakes. You can use grated parmesan in place of the pecorino, but you may need to adjust the salt since parmesan has less salt than pecorino. Note: part of the dressing does not touch the raw chicken and gets reserved to drizzle on top of the chicken after it’s cooked, but can also be used for a salad.

How to grill chicken thighs with Italian dressing
Each number corresponds to the numbered written steps below.
- Trim the chicken thighs of any large pieces of fat.

- In a large bowl, whisk together the oils, vinegar, parsley, garlic, oregano, red pepper flakes, Dijon, and cheese. Reserve 3/4 cup of the dressing/marinade for use later on.
- Place the chicken into a sealable bag or bowl and pour the marinade on top of the chicken. Refrigerate for at least 4 hours, but preferably overnight. Remove the chicken from the fridge when you’re ready to cook and discard the marinade that touched the raw chicken.
- Preheat a gas or charcoal grill to medium heat and lightly oil the grates. Grill the marinated chicken thighs for 7-8 minutes per side or until nicely charred.

- If the thighs start to burn, move them to a cool side of the grill for indirect cooking. Close the grill, leave the top vent open, and cook until the thighs reach 180°F when checked with a probe thermometer.
- Transfer the grilled chicken thighs to a plate and drizzle with the remaining 3/4 cup of Italian dressing, or save the dressing to use on your favorite salad.
Top tips
- The grill. You can use a charcoal or gas grill for this recipe. If using charcoal, I recommend leaving 1/3 of the grill free of charcoal as a “cool spot” that allows for indirect cooking. If using gas, leave one burner side of the grill off.
- Serving. Grilled chicken thighs are great on their own, but you can also use them to make sandwiches or slice them on top of salads.

Instructions
- Trim the chicken thighs of any large pieces of fat.
- In a large bowl, whisk together all of the Italian dressing ingredients. Season with salt and pepper to taste.
- Reserve and set aside 3/4 cup of the Italian dressing marinade. Pour the remainder into a zip lock bag with the boneless chicken thighs. Refrigerate overnight or a minimum of 4 hours.
- When ready for grilling remove the chicken from the bag and dispose of marinade.
- Preheat a gas or charcoal grill to medium heat. Lightly oil the grates and grill the thighs for 7-8 minutes per side or until nicely charred. Cook until internal temperature of meat reaches 180°F. Note: If the thighs start to burn, move them to the cool side of the grill for indirect cooking. Simply close the grill, leaving the top vent open and cook until the thighs reach 180°F.
- Plate and serve the chicken thighs with a drizzle of the remaining 3/4 cups of Italian dressing. The rest of the dressing can be saved or used for a salad. Enjoy!
Notes
- Type of chicken. You can also use bone-in chicken thighs or chicken breasts or cutlets. Bone-in thighs should be cooked to an internal temperature of at least 180°F and chicken breasts and cutlets 160°F.
- Fat removal. Remove any large pieces of fat from the boneless thighs if present, but do not worry about small bits of fat.
- Type of grill. All grills are different so use the time as a general grilling guideline making sure to cook to an internal temperature of 180°F. It’s a good practice to keep 1/3 of a charcoal kettle grill free of charcoal for indirect cooking or leaving one burner side of the gas grill off.
- Indirect cooking. If the thighs start to burn, move them to the cool side of the grill for indirect cooking. Simply close the grill, leaving the top vent open and cook until the thighs reach 180°F.
- Salt levels. No salt was added due to the salt content of the pecorino cheese. But taste test the marinade after whisking and more salt and pepper if required.
- Italian dressing. 3/4 cup of the remaining dressing can be used for a salad or drizzled on top of the chicken.
- Leftovers. The grilled chicken thighs can be saved in the fridge for up to 3 days and can be reheated in the microwave or oven.
