This is just the overview so you can see what you’re actually getting into here. When you are cooking, you’ll want to use the full recipe at the bottom of the page.


Prep and Season

Make sure your fish doesn’t have any lingering bones. Season with salt and pepper.



Fire up that griddle and get it heated to medium-low heat. Fish is delicate and doesn’t really need much heat to cook it.

Mix up the lemon zest, juice, and garlic paste and smear it on one side of your fish fillets.



Put down butter and place the fish fillets on it. If there’s skin, put that skin side on the hot surface.

Place the lemon slices down on the griddle in groups of two. Put a piece of thyme on top.

After 2-3 minutes, flip the fish over ONTO the lemon slices. Cover with the dome and cook for another couple of minutes before squirting in some of the white wine, to steam the fish.



Remove the dome and check the temp of the fish. It should be about 125°F in the middle for the best results. I like to put my spatula under the lemons and all and flip it over, carefully, onto the serving plate.

Fish on the Blackstone FAQ

Can this dish be made in advance?

Nope! Fish needs to be made and served right away for the best results.

What’s the best way to store and reheat leftovers?

Plan well and only make what you’re going to eat in one serving for the best results. Reheating fish is not ideal, in any situation, but if you DO have some extras just please for the love of all that is good and holy keep it out of the microwave.

Sure! Change things up and make it your own. If you have a favorite fish rub or seasoning blend, use that in place of the salt and pepper. Don’t love garlic? Skip it! As with all of our recipes, we encourage you to make it your own.

Making fish on the Blackstone is so easy! Any kind of fresh fish will work with this recipe. The fresher the better! This will get dinner on the table in a flash.

Prep Time 5 minutes
Cook Time 10 minutes
Total Time 15 minutes


  • 16 ounces boneless fish fillets
  • 1 lemon, sliced into rounds
  • 2 teaspoons flaky salt
  • 1 teaspoon ground pepper
  • 2 teaspoons lemon zest
  • 1 tablespoon lemon juice
  • 2 teaspoon garlic paste (we like Gourmet Garden, but you can use fresh garlic too and grind it into paste if that's your thing.)
  • 4 teaspoons butter
  • 4 tablespoons dry white wine
  • 4 sprigs fresh thyme


  1. Prep your fish by feeling it to ensure there are no remaining bones. Season with salt and pepper.
  2. Preheat your griddle to medium-low heat.
  3. Mix together the lemon zest, lemon juice, and garlic paste.
  4. Spread the lemon/garlic mixture over the top of each of the fish fillets.
  5. Put down a small pat of butter on the griddle for each piece of fish you'll be cooking.
  6. If your fish fillets have skin on one side, start them skin-side down on the griddle in the butter.
  7. Place groups of two lemon slices down together on the griddle near each other. This is what you're going to flip the fish ONTO. Put a sprig of thyme on top of the lemon slices.
  8. After the fish cooks for 2-3 minutes, flip it onto the lemon slices and thyme. Cover them all with a cooking dome. Let it cook for 3-4 minutes, and then squirt some of the dry white wine under the dome and onto the lemons on the bottom to let the fish steam.
  9. Remove from the griddle and serve immediately. I like to slide the spatula right under the lemon and then carefully flip the whole lemon and filet onto the serving plate.


How long you need to cook your fillet depends entirely on how thick your fillet is. If you have a fillet that is less than 1" thick, you'll want to cook it for less time. If it is thicker, cook a little longer. The key to GREAT fish is to not overcook it. It should lightly flake but still be moist.
