How to Make Blackstone Blackened Fish

Start by mixing together all of the spices in a small bowl to make the blackened seasoning blend. Then preheat your Blackstone to a high heat.

Place cut and cleaned filets onto a cutting board and use a basting brush to coat them in melted butter. Sprinkle the filet with blackening seasoning and then flip it over and repeat the process on the other side.

Melt three tablespoons of butter on the preheated griddle, then place each seasoned filet onto the melted butter. Squeeze the halved lemon over the filet of fish.

Once there is a good char on the fish, flip it to cook the other side. Then cook for 2-3 more minutes until the fish is done. Once it is flaky, it’s done!

Pull the fish off of the Blackstone and allow it to rest before serving. Enjoy!

How to Store Leftover Blackened Fish

Allow the fish to cool completely and then transfer each filet to an airtight container. You can also wrap them separately in plastic wrap or aluminum foil.

FRIDGE: Store in the fridge for 2-3 days.

FREEZER: Wrap individually in plastic wrap or aluminum foil and then place into a freezer bag. Freeze for up to 3 months.

What to Serve with Blackstone Blackened Tilapia

Pair this delicious dish with simple sides like grilled cauliflower or grilled sweet potatoes. You can even make a fish sandwich or serve this on tortillas to make fish tacos. Top it with some extra lemon juice and coleslaw for the BEST tacos!

Some grilled corn salad or corn salsa would be tasty served on top of the blackened fish.

How do I keep my fish from sicking to Blackstone?

You need to make sure that your flat top grill is not too hot and is also greased very well. Blackstone blackened fish will stick pretty quickly if cooked at too high of a temperature or on an ungreased surface. Use butter, olive oil, or avocado oil for the best flavor and best results for a non-stick surface.

Is butter good for cooking fish?

Yes! Salted and unsalted butter both work great when cooking fish. You can add so much flavor to fish by cooking it with butter. However, avocado oil and olive oil are both great substitutes if you cannot have butter or do not have it on hand.

This delicious Blackstone blackened fish recipe hits the mark every time. It delivers on flavor, quality and simplicity! Such a winner of a recipe.
