You might be thinking, grilled lettuce? Why grill something that’s supposed to be eaten cold. Well, that’s because grilling lettuce makes the exterior of it caramelized and smoky, which contrasts really well with the crispy cool interior of lettuce. It might just be the key to getting your kids to eat more lettuce! Plus, it’s just a fun way to serve lettuce in the summertime when the grill is already fired up.

Ingredients to make grilled romaine lettuce
- Romaine lettuce: You want to get the hearts of romaine for this recipe. You can usually find them pre-packaged at the grocery store, or you can buy a whole head of romaine and cut out the hearts yourself.
- Lemon: Makes the romaine pop with flavor and brightens up the vinaigrette.
- Dijon mustard: This adds a little bit of spice to the vinaigrette.

How to make grilled romaine lettuce
Before we get to grilling, there is a little prep work involved. You’ll want to make sure you don’t skip any of the trimming steps below!
Prepare The Romaine Lettuce
- Trim the lettuce heart bottom while making sure to keep it intact.
- Trim the top of the lettuce to remove some of the curly ends.
- Cut each lettuce head lengthwise in half.
- Brush the dressing over the lettuce on all sides, making sure to get the dressing between the leaves as much as possible.
Grill Romaine Lettuce
- Place the romaine lettuce cut side down on a preheated grill.
- Let the lettuce sit undisturbed until ready to turn or remove from the grill.
- Use tongs and remove immediately once desired charred has occurred.
Tips for making grilled romaine hearts
- Don’t forget to cut off the curly ends of the lettuce. You can use those to make a salad later, but cutting them off for grilling helps to get crispier edges that are not wilted since the head of the lettuce tends to be softer.
- Grill only on one side for more crispy results. While you can flip the romaine lettuce to grill it on the other side, I prefer to only grill it on the cut side so that it retains its crunch after grilling.
- Use a basting brush. If you don’t have one, you can use a spoon. This helps to evenly distribute the vinaigrette on the lettuce without oversaturating it or making it soggy.
- Be careful not to overcook! The key to grilled romaine is that it’s still crisp and crunchy. You don’t want it wilted or soggy. Ensure that your grill is hot before adding your hearts.
