Grilled fish with a fresh microgreen salsa verde is one of the simplest and most impressive summer dinners you can make. The salsa verde takes about five minutes to prepare, uses a generous handful of microgreens blended with traditional Italian herbs and bright lemon, and pairs perfectly with the smoky char of grilled fish. This is the dish I bring out whenever we have company during the summer because it looks restaurant-quality but requires almost no effort.

The magic of this recipe is the microgreen salsa verde. Traditional salsa verde relies on parsley, capers, anchovies, and olive oil. My version swaps in a mix of microgreens — cilantro, basil, and radish — for a more complex flavor profile with peppery heat, herbal brightness, and a subtle sweetness that complements the fish beautifully. It is also packed with concentrated nutrients that make this dish as healthy as it is delicious.

Which Fish Works Best for This Recipe?

You want a firm-fleshed fish that holds up on the grill without falling apart. Here are my top picks, with a Florida focus:

Mahi-mahi is my first choice. It has a slightly sweet, mild flavor that lets the salsa verde shine, and its firm texture makes it practically foolproof on the grill. Mahi-mahi is abundant in Florida waters from spring through fall.

Red snapper is a classic Florida fish with a delicate, nutty flavor. Grill it skin-side down for crispy skin that adds wonderful texture contrast to the bright salsa verde. If you can get it fresh from a local fish market, even better.

Grouper is the quintessential Florida fish — thick, meaty fillets that are almost impossible to overcook on the grill. Black grouper and red grouper both work beautifully here.

Swordfish is excellent if you want something heartier. Its steak-like texture stands up to bold flavors, and the salsa verde cuts through its richness perfectly.

In a pinch, salmon, sea bass, or even thick-cut cod fillets work well too. The key is choosing fillets that are at least three-quarters of an inch thick so they do not dry out on the grill.

How Do You Make Microgreen Salsa Verde?

Microgreen Salsa Verde

Makes about 1 cup — enough for 4 servings of fish

Ingredients:

2 cups packed microgreens (a mix of cilantro, basil, and radish works beautifully)
1/2 cup fresh flat-leaf parsley leaves
1/4 cup fresh mint leaves (about 8 to 10 leaves)
2 tablespoons capers, drained
1 small clove garlic, roughly chopped
1 anchovy fillet (optional, but recommended for depth of flavor)
Zest of 1 lemon
2 tablespoons fresh lemon juice
1 teaspoon Dijon mustard
1/2 cup extra-virgin olive oil
1/4 teaspoon red pepper flakes
Salt and freshly ground black pepper to taste

Instructions:

Combine the microgreens, parsley, mint, capers, garlic, anchovy (if using), lemon zest, lemon juice, and mustard in a food processor. Pulse 8 to 10 times until roughly chopped but not pureed. You want some texture.
With the processor running on low, slowly drizzle in the olive oil until the mixture comes together into a loose, spoonable sauce.
Stir in the red pepper flakes. Season with salt and pepper to taste.
Transfer to a bowl, cover, and let sit at room temperature while you grill the fish. The flavors will meld and improve over 15 to 20 minutes.

Variation: For a spicier version, add a small jalapeno (seeded) or swap the radish microgreens for mustard microgreens, which bring serious heat. If you love pesto-style sauces, check out our microgreen pesto three ways for more ideas.

How Do You Grill the Fish Perfectly?

Grilled Fish

Serves 4

Ingredients:

4 fish fillets (6 to 8 ounces each), about 3/4 to 1 inch thick
2 tablespoons olive oil
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
Lemon wedges for serving

Instructions:

Prep the grill: Heat your grill to medium-high (400 to 450°F). Clean the grates thoroughly and oil them well by dipping a folded paper towel in oil and rubbing it across the grates with tongs. This is the single most important step for preventing sticking.
Prep the fish: Pat fillets completely dry with paper towels. Brush both sides with olive oil and season generously with salt and pepper. Let the fish come to room temperature for 10 minutes before grilling.
Grill: Place fish on the grill presentation-side down (skin-side up if there is skin). Do not move the fish for 4 to 5 minutes. It will release naturally from the grill when it is ready to flip. Flip once and cook an additional 3 to 4 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 145°F.
Rest and serve: Transfer fish to a platter and let rest for 2 minutes. Spoon a generous amount of microgreen salsa verde over each fillet. Serve with lemon wedges and extra salsa verde on the side.

What Should You Serve with Grilled Fish and Microgreen Salsa Verde?

This dish pairs beautifully with simple sides that do not compete with the bright salsa verde:

Grilled zucchini or summer squash — toss with olive oil and grill alongside the fish
Coconut rice — the subtle sweetness complements the herbaceous salsa perfectly
Roasted fingerling potatoes with fresh rosemary
A simple microgreen salad — see our summer microgreen salad recipes for inspiration
Grilled corn on the cob with lime butter
Crusty bread for sopping up the extra salsa verde (do not skip this)

Can You Make the Salsa Verde Ahead of Time?

Yes, with some caveats. Microgreen salsa verde is best served within a few hours of making it because the microgreens will darken slightly over time. However, you can make it up to 24 hours ahead and store it in an airtight container in the refrigerator with a piece of plastic wrap pressed directly on the surface to minimize oxidation.

If making ahead, hold back the lemon juice and add it just before serving. The acid accelerates the color change. The flavor will still be excellent even if the color dulls a bit.

For the salsa verde, any combination of microgreens works, but I especially love using cilantro microgreens for their intense flavor, basil microgreens for sweetness, and radish microgreens for peppery kick. Growing your own means you always have the freshest possible greens for recipes like this — and there is something deeply satisfying about a dish that goes from grow tray to plate in minutes.

This is summer eating at its finest. Fire up the grill, make the salsa verde, and enjoy one of the best ways to showcase microgreens in a main course.
