Blackstone Sturgeon with Lemon Cream Sauce

Fire up the griddle and cast those lines because with this Blackstone Sturgeon with Lemon Cream Sauce we take fresh sturgeon fillets that are seasoned and seared right on the Blackstone and then sauce them with an umami-rich lemon cream sauce, whipped up on the stovetop (or in a saute pan on the griddle).

Blackstone Sturgeon with Lemon Cream Sauce

This sturgeon was such a treat. We do a lot of ocean fishing here, and sturgeon hasn’t been something that we’ve went away so far. This winter, Jeremiah got the opportunity to hit the water with Cannon and Kylie and bring home some sturgeon filets to cure those “no fishing in the winter” blues.

I’d never tried sturgeon before this, and it was so good! Sturgeon isn’t a light, flaky fish. It is more meaty, like veal or even chicken breast. If we’re comparing the texture of sturgeon to another fish, the closest we’ve ever eaten is swordfish.

Sturgeon cooks quickly, like all fish, so if you can get your hands on some it is a great protein option and tastes amazing.

How to make Blackstone Sturgeon

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.

1

Season and preheat

Season the fish and preheat the griddle over medium-high heat.

2

Cook the fish

4 minutes per side is about right! Use your best judgement though. How long it needs to cook depends on what type of fish and how thick your fillet is.

3

Sauce time

Make the sauce by sauteing the shallots and garlic in olive oil, then adding in the lemon juice, mushroom powder, and cream. Finish it off with your butter.

You can make this either inside on your stovetop or using a small saute pan on the griddle.

4

Serve

We served this over rice with a generous pour of sauce, and sprinkled with green onions and some more lemon juice.

Blackstone Sturgeon FAQ

Can you use another type of fish for this recipe?

You sure can! Halibut, swordfish, mahi mahi, grouper, rockfish, walleye, or pretty much any whitefish would work well with this recipe and this sauce.

How do you store and reheat leftovers?

Ideally, you won’t have any leftovers. Fish is best served immediately after cooking. Reheating can negatively impact the texture. If you DO wind up with some extras, a sous vide would be the ideal way to reheat. If you don’t have one of those, a freezer baggie in a pan of warm water also works!

Are there any substitutions for the mushroom powder?

Nope! You can make mushroom powder by pulverizing dried mushrooms, but I highly recommend picking up a jar of mushroom powder (linked in the recipe card), or just omitting it entirely. The sauce is still really great without it too.
