The Onion Trick That Replaces Heavy Cream: Tender Pollock in Just 15 Minutes

Read in another language:

Let’s be honest: how many times have you bought pollock only to end up with dry, rubbery pieces that nobody really enjoyed? I’m sure it’s happened to all of us. We are used to thinking of this fish as something boring, cheap, and strictly “cafeteria style.” But I decided to break that stereotype in my own kitchen, reports MODISTA.

As it turns out, making pollock incredibly tender and juicy doesn’t require drowning it in expensive heavy cream or sour cream. You don’t need any butter either. The whole magic lies in slicing the onions correctly and getting the simmering time just right.

Required Ingredients

• Frozen pollock — 3-4 whole fish
• Yellow onions — 2-3 large heads
• Vegetable oil for frying — 4-5 tbsp
• Salt — 1 tsp (or to taste)
• Ground black pepper — to taste

Step-by-Step Cooking Process

Step 1

First, fully thaw the fish (preferably in the fridge rather than hot water, so the flesh doesn’t fall apart), wash it thoroughly, and scrape away the black film inside the belly—it’s what causes bitterness. Cut the fish into small, bite-sized pieces. Sprinkle with salt and black pepper, toss well with your hands, and let it rest on the cutting board for a couple of minutes to let the spices penetrate the fish.

Step 2

While the fish rests, prep the onions. You really need a lot of them! Slice them into half-moons or dice them up. Heat a skillet with vegetable oil and toss in the onions. Sauté over medium heat until translucent and soft. You don’t want them burnt or heavily browned—juiciness is what we’re going for.

Step 3

Place the pollock pieces directly on top of the bed of onions. Mix gently, turn the heat down to low, cover tightly with a lid, and simmer for exactly 10 minutes. At this point, the onions release plenty of juice, which steams into the fish under the lid, creating that velvety, rich texture.

Step 4

Remove the lid, carefully flip each piece over, and cook for a few more minutes uncovered to let any excess moisture evaporate.

Meanwhile, as the fish simmers, I always whip up a quick side dish—fluffy rice or smooth mashed potatoes work like magic here.

So, dish out your side, top it with the hot onion-infused pollock, call everyone to the table, and enjoy your meal!

Dish History and Features of Pollock

Pollock is one of the most popular species of the cod family in the North Pacific Ocean. In European and East Asian cuisine, this fish is prized for its lean white meat free of tiny bones. Thanks to its low fat content, pollock is considered a staple for healthy eating, though that also makes it easy to dry out during cooking. Simmering it with a generous amount of vegetables originated as a clever home kitchen trick to keep the fillets moist without adding extra animal fats.

Advice from MODISTA

• Always scrape off the thin black film inside the pollock’s belly with a knife, or the fish will taste bitter.
• Don’t hold back on onions: the more you have in the pan, the juicier the resulting pan sauce will be.
• If you want to add a bit of zesty flavor, throw in a pinch of garlic powder or a quick squeeze of fresh lemon juice right at the end.
