Key Ingredients

- Little Gem lettuce: Crisp, sweet lettuce that serves as the base of the salad. Baby red leaf lettuce, romaine hearts, butter lettuce, or a combination of lettuces can be substituted.
- Castelvetrano olives: Mild, buttery olives that add a salty contrast, green olives, Kalamata olives, or your favorite olive variety will work.
- Watermelon radish: Adds color, crunch, and a mild peppery flavor. Regular radishes, Easter egg radishes, or thinly sliced cucumber can be substituted.
- Parmesan cheese: Freshly grated Parmesan adds a savory, salty finish. Pecorino Romano, Asiago, or shaved Parmesan are great alternatives.
- Red onion: Marinated in olive oil and balsamic vinegar to soften its bite and add brightness to the salad. Sweet onion or shallots can be used instead.
- Balsamic vinegar: Red wine vinegar, champagne vinegar, or white balsamic vinegar can be substituted.
- Everyday Seasoning Blend: Adds balanced savory flavor to the onions. Substitute with kosher salt, black pepper, garlic powder, onion powder, and a pinch of dried herbs.
- Panko breadcrumbs: Toasted until golden for a light, crispy crunch throughout the salad. Regular breadcrumbs can be used, though the texture will be slightly different.
- Spring onions: Grilled and blended into the dressing for a sweet, mellow onion flavor. Green onions or scallions are the best substitutes.
- Dill: Adds brightness and freshness to the dressing. Fresh parsley, chives, basil, tarragon, or a combination of herbs work well.
- Tahini: Creates a creamy texture and subtle nutty flavor in the dressing. Greek yogurt, mayonnaise, or a small amount of sour cream can be substituted.
- Dijon mustard: Adds tang and helps emulsify the dressing. Whole grain mustard or yellow mustard can be used if needed.
How to Make the Little Gem Salad
Let’s talk a little about how to make the lettuce salad (The printable instructions are in the recipe card below.)
Quick overview:
- Marinate red onions, slice radish, chop olives, make crispy panko bread crumbs.
- Prep lettuce, grill spring onions and blend dressing.
- Combine salad and enjoy!

Marinated red onions:
- First, thinly slice a red onion by hand or using a mandolin. Then, in a mixing bowl combine the onions, olive oil, balsamic, and seasoning blend. Stir to combine, cover, and let sit for 30 minutes.
- These can be kept in the fridge and are great on sandwiches, salads, pizza, and more. The marinade can be used as a dressing as well!
Crispy panko:
- Secondly, In a saute pan over medium-high heat combine the panko bread crumbs and olive oil. Stir to combine and toast for 4-5 minutes, keeping medium-high heat, until golden brown, stirring often so they don’t burn. Remove from heat and let sit.

Grilled spring onion dressing:
- Preheat a gas grill over medium-high heat. Once the grill reaches about 400 degrees F, add the spring onions, cook for a few minutes on each side or until they get a nice char on them. Remove from the grill.
- First, add grilled spring onions to a bullet or counter top blender along with the olive oil, tahini, Dijon mustard, fresh dill, salt, and pepper. Blend until the dressing is smooth, if needed add additional olive oil to thin out the dressing.
- Then to assemble the salad, layer lettuce, watermelon radishes, and chopped olives on a large platter. Top with some of the marinated red onions, freshly shaved parmesan cheese, a heavy drizzle of the spring onion dressing, and finish with the crispy bread crumbs! Enjoy immedaitely, dressing can be stored in an airtight container in the fridge for a week or two.
Rachel’s Chef Tips
- I love using toasted panko breadcrumbs instead of large croutons in this salad! It’s so much better to get a bite of crispy breadcrumbs in every bite rather then a big crouton. They distribute more evenly throughout the salad.
- The grilled spring onion dressing is the star of this recipe. Grilling softens the onion flavor and brings out a sweeter, more mellow flavor that blends beautifully into the dressing. My all-time favorite dressing to date!
- Don’t be afraid to swap the herbs based on what you have available. Dill is wonderful, but parsley, chives, basil, or tarragon all work well.
- Make the marinated red onions ahead of time. They keep in the refrigerator for up to 2 weeks and are great on sandwiches, grain bowls, tacos, and other salads. And save the onion marinade! It makes a flavorful vinaigrette base.
- If your dressing feels too thick, whisk in a splash of water or extra olive oil until it reaches your preferred consistency.
- Turn this side salad into a complete meal by serving it with grilled salmon, chicken breast, steak, or pork tenderloin. It’s especially good alongside anything cooked on the grill.

Notes
- Make the marinated onions ahead: The red onions can be prepared several days in advance and stored in the refrigerator for up to 2 weeks. Don’t discard the marinade, it makes a delicious dressing!
- Panko breadcrumbs work best: Instead of large croutons, toasted panko breadcrumbs add a salty crunch throughout the salad.
- Use the herbs you have on hand: Fresh dill is wonderful here, but parsley, chives, basil, tarragon, or a combination of herbs all work well in the dressing.
- Don’t skip grilling the spring onions: Grilling softens their onion flavor and brings out a sweeter, more garlic foward flavor.
- Adjust the dressing consistency: If the dressing is thicker than you’d like, whisk in a little extra olive oil or water until it reaches your desired consistency.
- Serve soon after assembling: For the best texture, toss the lettuce with the dressing just before serving so the breadcrumbs stay crisp.
- Make it a meal: This salad pairs beautifully with grilled salmon, chicken breast, steak, or pork tenderloin.
- Little Gem substitute: If you can’t find Little Gem lettuce, baby red leaf lettuce, romaine hearts, butter lettuce, or a combination of the two will work.
