Monkfish is the seafood equivalent of that quiet friend who shows up in a plain hoodie and then casually runs a marathon. It looks a little unassuming at the fish counter, but cook it right and you get sweet, firm, almost lobster-like bites with crisp edges and a tender center.

This is my favorite way to make it at home: a quick pan sear, then a lemon-caper butter sauce built in the same skillet. It’s bright, cozy, briny, and exactly the kind of dinner that makes you stop mid-bite and go, “Okay, wow.”

Serve it over mashed potatoes, rice, or with sautéed greens to catch every drop of sauce.

Why It Works

Crisp outside, juicy inside: Monkfish is lean, so we sear hard and finish gently to keep it tender.
One-pan sauce that tastes fancy: Butter, lemon, capers, and a little garlic turn the browned bits into a glossy, punchy pan sauce.
Reliable doneness: A quick temperature check prevents the number one monkfish problem, overcooking.
Accessible ingredients: Nothing weird, nothing fussy, just smart technique.

Storage Tips

Monkfish is best fresh, but leftovers can still be great if you treat them gently.

Refrigerate

Cool completely, then store monkfish and sauce in an airtight container for up to 2 days.

Reheat without drying it out

Stovetop (best): Add a splash of water or broth to a small skillet, warm the sauce over low heat, then nestle the fish in and cover for 3 to 5 minutes until warmed through.
Microwave (if you must): 50 percent power in short bursts with a spoon of sauce on top.

Freezing

I do not love freezing cooked monkfish because the texture can go a little bouncy. If you need to freeze, freeze the fish and sauce separately for up to 1 month and thaw overnight in the fridge.

Common Questions

What does monkfish taste like?

It’s mildly sweet and clean, with a firm, dense texture that people often compare to lobster or scallops. When it’s fresh, it tends to be more mild than “fishy,” but flavor can vary a bit by source and handling.

How do I know monkfish is cooked?

The easiest way is temperature. For the juiciest texture, I like to pull it at 135°F to 140°F and let it rest to about 145°F. It should be opaque and firm, but still juicy. Overcooked monkfish turns chewy fast.

Food safety note: If you prefer to follow strict USDA guidance for finfish, cook to an internal temperature of 145°F.

Do I need to remove the membrane?

Sometimes monkfish has a tough outer membrane on the outside. If you see a shiny, silvery layer, slide a knife under it and peel it off. Many fish counters already remove it, but it’s worth checking.

Can I use frozen monkfish?

Yes. Thaw overnight in the fridge, then pat very dry before seasoning. Extra moisture is the enemy of browning.

What can I substitute for capers?

Chopped green olives (Castelvetrano or pimento-stuffed) give a similar salty-briny pop. Use a little less, then taste.

Is monkfish safe if it looks a little translucent?

Use temperature as your guide. Monkfish can look slightly translucent in the thickest part right before it finishes. If it hits the safe range and rests, you’re good.

I have always had a huge passion for the culinary arts, people, working as a team, and so on. I wanted to pursue my love for cooking initially at Virginia Commonwealth University with a culinary arts degree; however, I instead decided to apply myself and acquire more practical skills. My end goal is to eventually open my own restaurant or similar establishment.

Kitchen Essentials

12-inch skillet (stainless steel or cast iron)
Fish spatula or thin metal spatula
Instant-read thermometer
Paper towels
Small cutting board and knife
Microplane or citrus zester (optional)

The first time I cooked monkfish at home, I treated it like a delicate white fish and gave it a gentle, polite sear. It came out fine, but it did not have that “restaurant” thing. Next try, I got a little braver: hotter pan, drier fish, and a butter sauce that actually tasted like something. The difference was instant. Now monkfish is my go-to when I want seafood that feels special without turning my kitchen into a full-time job.
