Using Blackstone grills to Roast Oysters

When you cook oysters on a grill or a Blackstone griddle it elevates them and enhances the flavor in ways that you simply can’t get when you eat them raw. Not to mention it helps to eliminate some of the food safety concerns that can come from eating uncooked mollusks.

Though there are some important details to mind when it comes to cooking oysters on a flat top grill like a Blackstone griddle.

You can steam them whole in the shell, or on the half-shell like you would for Oysters Rockefeller or Oysters Casino.

Though if you are going to steam them on the half-shell you will need to cover them with your griddle hood or something else that will trap the steam.

Can You Cook Oysters on a Blackstone Griddle?

As long as you have a wire rack like you usually find as a cooling rack in a half-sheet pan combo, you can easily cook oysters on a Blackstone griddle.

Though if you want to steam them on the half-shell, you will need to close the hood to trap in the heat and moisture.

If your Blackstone griddle doesn’t have a hood, you could cover the oysters on a wire rack with a sheet cake pan or a large tent improvised out of some heavy-duty aluminum foil.

Should You Cook Oysters on a Blackstone Griddle?

Cooking oysters on a Blackstone griddle is preferable to cooking them on an open-flame grill.

Not only do you get more consistent heating, and heat control, but you also get a more true oyster flavor without the smoky aroma open flame tends to create.

How Do You Steam Oysters on a Griddle?

Steaming oysters when they are whole and enclosed in their shell is as easy as placing them on a medium-heat griddle top.

They will essentially steam in their internal juices. They will be ready to eat when the adductor muscle releases and the hinge releases on the shell.

If you want to steam oysters on the half-shell, you need to use a Blackstone griddle with a hood or come up with some way to cover them enough to hold in the steam they release. This is like how you would cook Oysters Rockefeller.

If you need to add extra steam, you can simply squirt a little water on the griddle top near the oysters and cover them immediately.   

How Do You Cook Oysters on a Flat Top Grill?

Timing and temperature control are critical when it comes to cooking oysters on a flat top grill like a Blackstone griddle.

You also need to make sure you are working with properly shucked oysters, by opening the shell and carefully loosening the adductor muscle from the shell.

The most traditional dish for a griddle is Oysters Rockefeller, which includes topping them with sauteed garlic, shallots, and a drizzle of Hollandaise sauce.

Step One: Preheat the griddle to medium-low heat. Then add two tablespoons of olive oil, before lightly sauteing the shallots and garlic. If you want to add some spinach or collard greens, you can add them as well and allow them to wilt. This should take two to three minutes. Then roughly chop it with the edge of your spatula and remove it to a side bowl.

Step Two: Turn the burners on your flat top griddle to medium-high. Then prepare your favorite version of Hollandaise sauce.

Step Three: Place your shucked oysters face up on a wire cooling rack. The wire rack from a half-sheet pan will work just fine. If an oyster doesn’t want to lay evenly on its own, you can make a little nest for it out of heavy-duty aluminum foil.

Step Four: Place one to two tablespoons of your spinach and garlic mixture on top of the oysters, making sure that none extends over the edge of the shell.

Step Five: Lightly coat the top of the oysters with the Hollandaise sauce.

Step Six: Close the lid on your Blackstone griddle or cover the oysters completely with a cake sheet pan or a large tent made out of aluminum foil.

Step Seven: Let the heat buildup under the hood to warm the oysters and start to brown the tops of the oysters. This should take three to four minutes. If you check on them after two minutes and you see they are cooking unevenly, you should use a pair of tongs to turn the wire rack.

Step Eight: Remove the oysters from the griddle top, and let them cool. Then dress with a refreshing pinch of lemon.

Will Oysters Open on the Grill?

If you cook oysters in the shell, instead of on the half-shell, they will eventually steam in their own internal juices to open.

You can then dress them with butter, Hollandaise sauce, or your favorite oyster topping.

Final Thoughts

Bringing oysters to a Blackstone griddle or grill is a great way to add flavors that you just can’t get when you eat them raw. If you leave them in the shell and place them on the heat, they will steam in their own internal juices.

If you cook oysters on the half-shell on a flat top grill, you will need to close the hood or cover them to hold in the heat and natural steam.

Cooking oysters on a Blackstone griddle helps preserve more of their natural flavor than if you brought them to an open-flame grill.

This makes them a great option for elevating classic dishes like Oysters Rockefeller and Oysters Casino.
