How to Make Grilled Romaine Caesar with Pickled Onions, Parmesan, and Homemade Croutons Recipe

Step 1: Prepare the Pickled Onions

Start by making your pickled onions since they need some time to soak up their tangy, spicy flavors. Combine the white vinegar, sugar, red pepper flakes, allspice berries, bay leaf, and cloves in a saucepan and bring to a gentle simmer until the sugar dissolves. Place the thinly sliced red onions in a jar or bowl, then pour the hot vinegar mixture over them. Let them sit at room temperature for at least an hour to develop that perfect sweet-and-spicy snap.

Step 2: Make the Homemade Croutons

While the onions are pickling, get your homemade croutons started. Cut your dark rye or pumpernickel bread into bite-sized cubes. Drizzle with extra-virgin olive oil, toss to coat thoroughly, and toast them in a preheated oven or skillet over medium heat until they’re golden and crispy. These croutons will add a wonderful hearty crunch that perfectly offsets the charred romaine.

Step 3: Prepare the Caesar Dressing

Whisk together the egg yolk, chopped anchovy, garlic, lemon juice, and kosher salt until smooth and creamy. Slowly drizzle in your avocado or light olive oil while whisking vigorously to emulsify the dressing. Stir in Worcestershire sauce and freshly cracked black pepper for that authentic, zesty Caesar flavor that ties the whole salad together.

Step 4: Grill the Romaine Hearts

Brush the halved romaine hearts lightly with olive oil, then place them cut-side down on a hot grill or grill pan. Grill for 2-3 minutes until they develop fantastic charred grill marks and slightly softened edges, which intensifies their flavor and adds a smoky depth that truly transforms this Caesar salad.

Step 5: Assemble the Salad

Place your warm grilled romaine on a platter, then spoon over a generous amount of Caesar dressing. Scatter the pickled onions and homemade croutons evenly. Finish with plenty of shaved Parmesan cheese for sharpness and a beautiful, glossy finish that brings all the flavors together.

Garnishes

A sprinkle of extra Parmesan and a few freshly ground black pepper cracks on top always elevate this salad just right. If you want to add a little green freshness, some chopped fresh parsley or a few lemon zest curls add a bright pop that complements the smoky romaine.

Side Dishes

This Grilled Romaine Caesar with Pickled Onions, Parmesan, and Homemade Croutons Recipe pairs beautifully with grilled chicken, roasted shrimp, or a juicy steak for a complete, protein-packed meal. For a vegetarian twist, roasted chickpeas or marinated tofu on the side bring satisfying richness and texture.

Creative Ways to Present

Try serving the grilled romaine as individual halves on a rustic wooden board for a dramatic presentation. Drizzle the dressing artistically and scatter pickled onions and Parmesan around for a restaurant-quality look. Or toss everything together in a large bowl just before serving for a more casual, family-style vibe.

Make Ahead and Storage

Storing Leftovers

Keep leftover grilled romaine and pickled onions separate from dressing and croutons for best texture. Store romaine and onions in airtight containers in the refrigerator for up to two days to maintain freshness without wilting.

Freezing

Because the textures can change, freezing this salad isn’t recommended. The grilled lettuce tends to become limp and the croutons lose their crunch after thawing. It’s best enjoyed fresh.

Reheating

If you have leftover croutons, reheat them in a hot oven or toaster oven to revive their crispness. The grilled romaine is best served cold or at room temperature, so avoid reheating it to preserve its smoky flavor and texture.

FAQs

Can I use regular onions instead of red onions for the pickled onions?

Absolutely! Yellow or white onions work just fine for pickling, though red onions provide a lovely color and slightly sweeter bite that complements this salad perfectly.

Is the egg yolk in the dressing safe to eat raw?

To enjoy the richest flavor and safest option, use pasteurized eggs or prepare the dressing fresh and consume it promptly. If you prefer, you can also substitute with a prepared Caesar dressing.

How long can I keep the pickled onions?

Pickled onions will keep well in the refrigerator for up to two weeks, developing even more flavor over time—making them a great make-ahead component for this recipe.

Can I make this recipe vegan?

Yes! Swap the Parmesan for a vegan cheese alternative, use a vegan Caesar dressing, and skip the anchovy in the dressing. The grilled romaine and pickled onions remain just as delicious.

What’s the best bread for the homemade croutons?

Hearty, dense breads like rye or pumpernickel add wonderful flavor and hold up well when toasted, but sourdough or whole grain loaves also make superb choices.
