Juicy flank steak marinated in balsamic vinegar, grilled to perfection and sliced thin, sits atop a bed of crisp mixed greens alongside sweet charred corn, ripe cherry tomatoes, thinly sliced red onion, and creamy avocado. Crumbled Gorgonzola adds a bold, tangy richness that ties everything together. A simple balsamic-honey vinaigrette brings it all into balance. Ready from start to finish in just 35 minutes, this salad delivers restaurant-quality flavor with minimal effort — perfect for weeknight dinners or weekend gatherings.
A summer evening, the grill still radiating heat after dinner, and my neighbor leaning over the fence asking what smelled so incredible. That was the night this salad went from something I threw together into the dish people actually started requesting at every gathering.
I made this for a friend who swore she did not like blue cheese. She ate three helpings and then texted me the next morning asking for the recipe. The trick was letting the steak rest long enough so the cheese could soften without fully disappearing into the greens.
Ingredients
- Flank steak: This cut takes marinade beautifully and stays affordable, but slice it thin and across the grain or you will regret every bite
- Balsamic vinegar: Spend a little more here because cheap balsamic tastes like sweetened vinegar and ruins everything it touches
- Garlic: Fresh minced only, the jarred stuff has a weird fermented aftertaste that will haunt your marinade
- Dijon mustard: This is your emulsifier for both the marinade and vinaigrette, skip it and your dressing will separate into an oily mess
- Fresh corn: Frozen works in a pinch but fresh off the cob chars better and holds that sweet snap that makes the whole salad sing
- Mixed greens: Arugula adds a peppery bite that cuts through the rich steak and creamy cheese beautifully
- Gorgonzola: Crumble it yourself from a block, pre-crumbled has additives that keep it from melting properly
- Cherry tomatoes: Halving them releases their juices into the salad so every forkful gets a burst of brightness
- Red onion: Soak the slices in ice water for ten minutes if raw onion is too aggressive for your crowd
- Avocado: Add it last and gently fold it in so it holds its shape instead of turning into green mush
- Extra virgin olive oil: Use the good bottle for the vinaigrette, not the one you use for sauteing
- Honey or maple syrup: Just a touch balances the acidity of the balsamic without making the dressing sweet
Instructions
- Marinate the steak:
- Whisk the balsamic vinegar, olive oil, garlic, Dijon, salt, and pepper in a small bowl until combined. Place the steak in a zip-top bag, pour the marinade over, press out the air, and let it sit in the fridge for at least 20 minutes.
- Grill the corn:
- Brush the husked ears with olive oil and lay them on a medium-high grill. Turn them every few minutes until you get nice char marks, about 8 to 10 minutes total, then let them cool before slicing the kernels off.
- Cook the steak:
- Pull the steak from the marinade and let the excess drip off. Grill 3 to 4 minutes per side for medium-rare, then move it to a cutting board and resist the urge to slice it for at least 5 minutes.
- Build the salad base:
- Spread the mixed greens across a large platter or bowl, then scatter the grilled corn, halved tomatoes, sliced red onion, avocado, and crumbled Gorgonzola over the top.
- Whisk the vinaigrette:
- Combine the balsamic vinegar, olive oil, honey, Dijon, salt, and pepper in a bowl and whisk aggressively until the mixture thickens and turns slightly opaque.
- Assemble and serve:
- Drizzle the vinaigrette over the salad, arrange the sliced steak across the top, and get it to the table before the avocado starts to brown.
My sister-in-law now calls this her birthday dinner, which is both flattering and slightly absurd for a salad. But I get it, because the combination of hot steak, cold greens, and that tangy Gorgonzola hits every single craving at once.
Choosing the Right Steak Cut
Flank steak is my go-to here because it marinates fast and slices into beautiful ribbons. Skirt steak works just as well if you can find it, but avoid filet mignon since it lacks the texture to stand up to bold balsamic flavors.
Getting the Grill Marks Right
Do not obsess over perfect crosshatch patterns because the flavor comes from the char, not the aesthetics. Let the corn sit undisturbed for a couple minutes before rotating so it actually develops color instead of just getting warm.
Making It Ahead Without Ruining It
You can marinate the steak and grill the corn up to a day in advance, then keep everything in separate containers in the fridge. The vinaigrette also holds well overnight, just give it a good shake before using.
- Never dress the salad until you are ready to serve or the greens will wilt within minutes
- Keep the avocado pit in with leftover slices to slow down browning if you prep early
- Leftover sliced steak makes an incredible breakfast hash the next morning
This salad has become the meal I make when I want to feel like a competent adult without actually trying that hard. Good food does not need to be complicated, it just needs someone willing to let simple ingredients do their job.
Recipe FAQs
- → What cut of steak works best?
-
Flank steak or sirloin are ideal because they grill quickly and slice beautifully across the grain for tenderness.
- → Can I make this without a grill?
-
Yes, use a cast-iron skillet over high heat for both the steak and corn. You'll still get great sear and caramelization.
- → What can I substitute for Gorgonzola?
-
Blue cheese or feta both work well. Feta will be milder, while blue cheese keeps the bold, creamy character.
- → How long should the steak marinate?
-
At least 20 minutes, but up to 2 hours for deeper balsamic flavor. Beyond that, the vinegar can start breaking down the meat.
- → Is this gluten-free?
-
The ingredients are naturally gluten-free, but always check labels on Dijon mustard and balsamic vinegar to be sure.
- → Can I prepare components ahead of time?
-
Marinate the steak and grill the corn up to a day in advance. Store separately and assemble just before serving for the freshest results.
