Featuring tender, smoky grilled romaine hearts, creamy grilled avocado, a vibrant homemade roasted tomatillo sauce, and a sprinkle of salty cotija cheese, this salad promises an exciting burst of flavors and textures that will make you rethink how you prepare your greens!

This isn’t just another salad; it’s a culinary revelation. I can confidently say that this Grilled Romaine Salad is far more complex and interesting than the photos alone might suggest. It has quickly become one of the most intriguing and delicious salads I’ve crafted in recent memory. The magic truly happens on the grill, where humble romaine lettuce undergoes a remarkable transformation, shedding its usual crispness for a tender, smoky bite while retaining just enough satisfying crunch.
Why Grill Romaine Lettuce? Unlocking Unexpected Flavor
Grilling lettuce might sound unconventional, but it’s a technique that unlocks an incredible depth of flavor and texture. Romaine lettuce, with its sturdy structure and robust leaves, is perfectly suited for the high heat of the grill. Unlike delicate greens that would wilt into oblivion, romaine holds its shape beautifully. As it hits the grates, the outer leaves caramelize and char slightly, developing a subtle smoky bitterness that is both intriguing and delicious. The interior remains tender-crisp, offering a delightful contrast to the charred edges. This process not only softens the lettuce but also infuses it with an irresistible smoky aroma that elevates it from a simple side to a star component of the dish.

A Symphony of Flavors: Key Components of This Unique Salad
Beyond the surprising grilled romaine, this salad is a masterclass in balancing diverse flavors and textures. Each ingredient plays a crucial role in creating a harmonious and utterly delicious experience:
Smoky Grilled Avocado
Creamy avocado takes on a whole new dimension when kissed by the grill. The gentle char adds a smoky depth to its naturally buttery texture, enhancing its richness and preventing it from becoming too heavy. When sliced and grilled, avocado develops beautiful grill marks and a slightly firmer exterior while remaining lusciously smooth inside. Its cool, creamy presence provides a perfect counterpoint to the warmth and char of the romaine.
Zesty Roasted Tomatillo Sauce
The homemade roasted tomatillo sauce is the bright, acidic heart of this salad. Prepared from fresh tomatillos, aromatic onion, and pungent garlic, all roasted until tender and slightly charred, then blended with a touch of olive oil and fresh lime juice, it’s a revelation. Roasting intensifies the tomatillos’ tangy flavor, adding a subtle sweetness and a pleasant earthiness. This vibrant, piquant sauce cuts through the richness of the avocado and the char of the romaine, tying all the elements together with its invigorating acidity.
Salty Cotija Cheese
A generous sprinkle of finely grated cotija cheese introduces a salty, slightly pungent note and a fine, crumbly texture. Often referred to as “Mexican Parmesan,” cotija holds its shape well and offers a delightful savory kick that complements the other ingredients beautifully, adding depth and a burst of umami.
Fresh Green Onions
Sliced green onions provide a mild, fresh oniony flavor and a delicate crunch, adding another layer of texture and a burst of vibrant green color to the final presentation.

Crafting Your Grilled Romaine Salad: Step-by-Step Perfection
Achieving this salad’s perfect balance of flavors and textures is simpler than you might think. Here’s a detailed guide to ensure your success, focusing on each key component:
1. Prepare the Roasted Tomatillo Sauce
The foundation of this salad’s vibrant flavor begins with roasting. Preheat your oven broiler to high for maximum charring. On a foil-lined half sheet pan, spread out your quartered tomatillos, sliced small yellow onion, and peeled garlic cloves. Toss them with a tablespoon of extra virgin olive oil, then season generously with kosher salt and freshly ground black pepper. Broil for 10 to 15 minutes, flipping the vegetables a few times to ensure even charring. You’re looking for beautifully browned edges and very soft tomatillos, indicating their sugars have caramelized and their tanginess has mellowed. Allow the roasted vegetables to cool slightly before transferring them to a blender. You can choose to blend the sauce until it’s perfectly smooth for a refined finish or leave it slightly chunky for a more rustic appeal, depending on your preference. Once blended, let it cool completely to room temperature. Stir in two teaspoons of fresh lime juice, and taste – adjust with more salt, pepper, or lime juice as needed to achieve that perfect tangy balance.
2. Grill the Avocado
For the best grilled avocado, start with a ripe but firm avocado. It should yield slightly to gentle pressure but not be mushy, as overly soft avocados can fall apart on the grill. Cut the avocado in half, remove the pit, and carefully peel away the skin. Slice each half into ½-inch thick pieces. To prevent browning (oxidation), lightly toss the avocado slices with a squeeze of fresh lime juice. Then, lightly brush both sides of each slice with a small amount of vegetable oil – this prevents sticking and helps achieve beautiful grill marks. Heat your grill pan (or outdoor grill) over high heat. Grill the avocado slices for approximately 1 minute per side. Look for distinct grill marks and a slight softening. Set the grilled avocado aside to cool slightly.
3. Master the Grilled Romaine
Rinse and thoroughly dry your romaine lettuce heads. Excess moisture will prevent proper charring. Trim and discard the very top, softest leaves of the romaine hearts; these can be reserved for another salad or discarded. Slice each romaine heart in half lengthwise, ensuring the root end remains intact to hold the leaves together during grilling. Brush the cut sides of the romaine halves with olive oil and season with salt and pepper. For optimal results, use an outdoor grill over very high heat to get a deep, smoky char. If an outdoor grill isn’t available, a well-heated grill pan will also work wonders. Place the romaine halves cut-side down on the hot grill. Grill for about 2 to 3 minutes per side, or until the cut surfaces are nicely browned and slightly charred, and the leaves have softened but still retain some bite. The exact timing will depend on the heat of your grill.
4. Assemble and Serve
Once all your components are ready, it’s time to bring this masterpiece together. For each serving, spoon a generous amount of the cooled roasted tomatillo sauce onto a serving plate. Using the back of the spoon, create a swoosh or spread the sauce artfully across the plate. Carefully place one grilled romaine half on top of the sauce. Arrange 2 to 3 smoky grilled avocado slices alongside or on top of the romaine. Finish with a sprinkle of thinly sliced green onions and a hefty, indulgent dose of finely grated cotija cheese. This salad is best served immediately to enjoy the warmth of the grilled elements and the freshness of the sauce.

Instructions
-
Prepare Sauce: Preheat the oven broiler to high. Place the sliced tomatillos, sliced onion, and garlic on a foil-lined half sheet pan. Toss with the olive oil and season with salt and pepper. Roast under the broiler for 10 to 15 minutes, tossing several times, until the tomatillos and onions are evenly charred and the tomatillos are very soft.
-
Remove and allow to cool slightly before processing in a blender. Depending on your preference, you can either choose to make the sauce slightly chunkier or puree it until it is very smooth. Set the sauce aside to cool at room temperature. Add the lime juice and season with additional salt and pepper if needed.
-
Prepare Salad: Cut the avocado in half, pit, and remove the peel. Cut the avocado halves into ½-inch thick slices. Toss the pieces lightly with lime juice (to prevent oxidation). Brush the avocado slices with a small amount of oil (so they do not stick to the grill). Using a grill pan, grill the avocado slices over high heat for roughly 1 minute on each side. Set aside.
-
Meanwhile, trim and discard the top, soft leaves of the romaine hearts or reserve for another use. Slice the romaine hearts in half lengthwise. Brush the cut-sides with olive oil and season with salt and pepper. Using an outdoor grill (preferably) or a grill pan over very high heat, grill the romaine hearts until browned on both sides. Depending on the heat of your grill or grill pan, this will take approximately 2 to 3 minutes per side.
-
Assemble and Serve: For each serving, spoon roasted tomatillo sauce onto a serving plate and swoosh using the back of a spoon. Place one grilled romaine half on top of the sauce, and then top it with 2 to 3 grilled avocado slices, a sprinkle of sliced green onions, and a hefty dose of finely grated cotija cheese. Serve immediately.
Serving Suggestions & Creative Variations
This Grilled Romaine Salad is wonderfully versatile. While it shines as a light and flavorful main course, it also makes an excellent side dish. Consider serving it alongside grilled chicken, flaky white fish, or a perfectly seared steak for a complete meal. For a vegetarian feast, it pairs beautifully with black bean burgers or grilled halloumi cheese.
Feeling adventurous? Here are a few ideas to customize your grilled romaine salad:
- Add More Veggies: Grilled corn kernels, diced bell peppers, or black beans would make fantastic additions.
- Spice It Up: A pinch of chili flakes in the tomatillo sauce, or a few slices of fresh jalapeño, can add a welcome kick.
- Herbaceous Twist: Fresh cilantro or parsley chopped and sprinkled over the top can brighten the flavors even further.
- Different Cheeses: If cotija isn’t available, crumbled feta or a mild goat cheese could offer a similar salty creaminess.
- Protein Boost: Add some cooked and shredded chicken or grilled shrimp for a heartier meal.
Tips for Grilling Success
To ensure your grilled romaine salad turns out perfectly every time, keep these tips in mind:
- Don’t Overcrowd the Grill: Give your romaine and avocado slices enough space on the grill for proper charring and even cooking. Overcrowding can steam them instead of grilling.
- Hot and Fast: Romaine and avocado benefit from high, direct heat for a short period. This allows for charring without overcooking.
- Dry Romaine is Key: Ensure your romaine halves are thoroughly dry before oiling and grilling. Moisture creates steam and prevents browning.
- Ripe but Firm Avocado: As mentioned, this is crucial for the avocado to hold its shape on the grill.
- Serve Immediately: Grilled romaine is best enjoyed fresh off the grill while it still has its delicate warmth and smoky aroma. The contrast with the cool sauce and creamy avocado is what makes this dish truly special.
Frequently Asked Questions About Grilled Romaine Salad
New to grilling lettuce? Here are some common questions you might have:
Q: Can I use other types of lettuce for grilling?
A: Romaine is ideal due to its sturdy leaves and crisp texture that holds up well to heat. Other good options include endive, radicchio, or even thick slices of iceberg lettuce, but their cooking times and flavor profiles might vary slightly. Delicate greens like spring mix or butter lettuce are not suitable for grilling.
Q: Can I make the roasted tomatillo sauce ahead of time?
A: Absolutely! The roasted tomatillo sauce can be prepared up to 3-4 days in advance and stored in an airtight container in the refrigerator. This makes assembly quick and easy when you’re ready to serve your salad.
Q: How ripe should the avocado be for grilling?
A: For grilling, choose an avocado that is ripe but still firm. It should yield slightly to gentle pressure but not be soft or mushy. Overly ripe avocados can become too soft and fall apart on the grill.
Q: What if I don’t have an outdoor grill?
A: No problem! A grill pan works wonderfully for this recipe. Ensure your grill pan is preheated over high heat until it’s very hot before adding the romaine and avocado to achieve good char marks.
Q: Is this salad spicy?
A: The base roasted tomatillo sauce is tangy and savory, but not inherently spicy. If you prefer a kick, you can add a small jalapeño or serrano pepper to the tomatillos and onion before roasting, or stir in a pinch of chili powder or cayenne pepper to the blended sauce.
