Grilled Romaine with Caramelized Onion Noodles, Blue Cheese and Greek Yogurt Balsamic Dressing

I’ve been meaning to grill romaine since the early summer, when I spotted it in Bon Appetit mag. Why hadn’t I attempted grilling romaine yet?

Thinking out of the box with food is the key ingredient to staying on a healthy diet. Romaine, typically, is blah. It’s got a lovely crunch, but it’s not as highly touted as spinach or kale, because it’s not as rich in vitamins and other nutrients. Plus, it doesn’t have as much flavor.

But, how much can you really eat spinach and kale? Romaine should be loved too!


Now, by grilling romaine, we infuse the lettuce with healthy fats from olive oil and top it with deliciousness, and we’ve transformed boring ‘ole romaine into a magnificent salad that tastes and looks gourmet.

There are several parts to this dish that make it spectacular. Let’s start with the spiralized onions (I mean, can you blame me?) By spiralizing the onions, they are longer and therefore, more substantial. Typically, when you chop onions, they’re sliced and unexciting. Who likes slicing onions anyway?

Then, there’s the Greek yogurt balsamic dressing. I actually made a huge batch of this and saved some in the refrigerator and used it for a few salads throughout the week. If nothing else, make this dressing and ditch the recipe – it’s going to be one of your go-tos, I promise! It’s tangy, balsamic-y, and high in healthy protein. Typically, creamy balsamics are made using mayonnaise (ick!) This uses Greek yogurt instead. If you like a little more tang, add in another teaspoon of Dijon mustard!

Now, the blue cheese gives a robust flavor, another source of protein and a creaminess to this salad that completes the dish. However, if you’re a blue cheese hater, you can ditch the cheese or substitute in some shaved parmesan cheese or even use feta.

Let’s just say that when you dig your fork and knife into this “salad” (which, by the way – how cool is the presentation?), your bite will have so many textures, flavors and warmth that you won’t even realize you’re eating mundane romaine. Mundane romaine – it rhymes!

Warmed lettuce also has an elegant taste and fixes that “I don’t want to eat another salad” issue. I’ve been there.

Have you ever tried grilled romaine? Or grilled lettuces in general?

  • 2 romaine lettuce heads, rinsed, ends chopped off and cut in half lengthwise
  • 2 tablespoon extra virgin olive oil
  • salt and pepper, to taste
  • 1 onion, peeled, Blade A
  • 1/4 teaspoon garlic powder
  • 1/2 cup crumbled blue cheese
  • For the dressing:
  • ¼ cup nonfat plain Greek yogurt
  • 3 tablespoon balsamic vinegar
  • 2 teaspoons Dijon mustard
  • 1 tablespoon honey
  • salt and pepper, to taste


  1. Preheat the grill or grill pan to medium-high. Place half the olive oil in a bowl and while the grill is heating, brush the cut sides of the romaine lettuce with the olive oil. Season the cut side generously with pepper and lightly with salt.
  2. Once grill pan is heated, place the sliced side down and let cook for about 5 minutes. Periodically, put medium pressure with a spatula on top to ensure the lettuce cooks. Repeat until all lettuce halves are cooked. Set aside.
  3. After two lettuce halves have cooked, in another skillet, add in the rest of the olive oil. Once oil heats, add in the onion noodles and season with salt, pepper and garlic powder. Cook for 5-7 minutes or until caramelized and lightly browned.
  4. Top the grilled lettuce with onions and blue cheese and drizzle with balsamic vinaigrette.

Ooooohhh yes I will be making this one for sure!
Martha says:
Sounds delicious. Question: Can you spiralize beets and sweet potatoes and freeze them to be cooked at a later date?
Thanks! Yes, check out my How To page for a post on that!
I actually griddle/fry with baby gem lettuce quite a lot and it's fantastic. Don't know if it has the same name in the states as here in Scotland, but that it's name here. Actually think it better than the romaine lettuce.
Martha says:
Thank you so much for your prompt and helpful reply!
Sarah says:
Mmm looks so scrum-didly-umptious! I'd have to add some nuts, walnuts maybe or pine nuts even!
Soooo good. As soon as I got the email I made this for my mum and myself for lunch and we both LOVED it :)
Rose says:
I love grilled romaine, I will for sure try this. I usually just top with bacon bits and top with dresssing. This looks delicious.
Joanne says:
Mundane romaine is definitely a pet peeve of mine! I bet I'd love it grilled, though. All that smokiness and crispy crunchiness. Mmm.
Yummy, I'll definitely try this one. And while we're on the subject of romaine lettuce, I've recently discovered a great trick to make endless supplies of this veggy. Check it out - it's real magic
Meagan says:
So cool! Any thoughts on BBQing it? Rather than grilling in a pan I mean. Thinking it might give it that smoky BBQ flavour. Also- LOVE your site! Going to make this, cold kimchi cucumber noodles and chicken breast for dinner.
Yes, of course you can! That would add another dimension of flavor, for sure! I use a grill pan because many don't have easy access to a grill. Let me know how your dinner turns out!
Gayle says:
FABULOUS! Made it today. I reduced balsamic and used sugar free honey to reduce carbs- it was still wonderful! Thanks for your great recipes!!!
Stacey says:
Great recipe! Thanks for sharing. Grilled the romaine and some marinated chicken breast. Plus cooked the onions in a cast iron skillet on the grill at the same time. Skipped the cheese as chicken added a bit of tang & texture. def a keeper
This sounds lovely. Going to give this a go. thanks for sharing this recipe. Simon

I'm a total emotional eater. 🤡🙋🏻when I'm feeling sad, mentally tired, or just 'off,' I eat. to me, food is therapeutic and cooking is cathartic. and while yes, I often reach for something chocolatey or a literal bag of bread 🍞, I usually want a long therapy session in the kitchen and since I don't bake, it usually ends up some sort of pasta, an epic sandwich, or like today, with this flavorful salad. 🥕⁣

I woke up in a little bit of a funk and I decided to make a fancy salad for lunch and this Roasted Carrot & Beet Farro Salad with goat cheese, pecans, cranberries, and frisee lettuce was born. 30 minutes later, I feel much better, and now I'm waiting to digest so I can hop on the @onepeloton, squeeze in a quick workout and end my day early to spend it prepping for Luca's birthday festivities tomorrow. 🎉 🎈 ⁣

speaking of - anyone have any tips for building a balloon garland??? 😅

every night, I have this ritual where I scroll through the photos taken from the day on my phone and pick a favorite, posting it up on my stories with the hashtag #favoritepicoftheday. it’s a fun, sometimes therapeutic way to end and reflect on the day. as I was going through it tonight, the TV was on and I heard the news. ruth bader ginsburg passed away tonight. immediately, I felt sadness and a bit of worry. a worry of the implications politically of her passing. there’s so much at stake in this upcoming election and you all know I don’t get political on here very often, but seeing roma’s little smiley, silly face made me realize that if I’m not being a good role model and using this platform to make the world a better place for her, what kind of mother am I? so VOTE, VOTE, VOTE. 🇺🇸 and as the late RBG said, “real change, enduring change, happens one step at a time.” here’s my step. 💕 #rbg #ruthbaderginsburg ...
