Creamy baked fish on potato gratin
This dish offers off very French-country vibes. Which, in hindsight, is reasonably unsurprising given it’s a recipe that our very personal Chef JB simply casually threw collectively at some point. We ate it, cherished it a lot, declared it was “website-worthy” then proceeded to remake it…oh, I don’t know. Possibly 10, 12 occasions earlier than we have been absolutely proud of it and closed out all of the “what ifs”?
Mainly, it’s a creamy potato gratin, heavy on the leek (or onion), with fish that’s baked on prime on the similar time, coated in a crunchy golden breadcrumb topping. So basically, the breadcrumb topping acts as a lid, conserving every little thing steamy and succulent because the fish bubbles away within the creamy sauce, absorbing the fish juices.
It’s simply an all-out cosy dish of scrumptious cosiness!



Substances
Right here’s what it’s good to make this:
Finest fish

I like to make use of barramundi (pictured above), snapper and ling for this recipe. I used to be going to suggest white fish fillets, however really, salmon and trout will work high quality too. Simply intention for one thing that’s round 2 cm / 0.8″ thick . We want fillets that aren’t too skinny so it may be baked within the oven with out overcooking.
Pores and skin on or off? Both is ok, it actually received’t have an effect on the bake time. However the pores and skin received’t be crispy. If this can be a turn-off for you, simply eat the flesh and go away the pores and skin.
Appropriate fish
This recipe is finest made with the extra delicate white fish fillets which can be round 2 cm (0.8″) thick. Our favorite fish to make this with is barramundi. Listed here are some extra fish with comparable cooking traits that can work nice:
barramundi (pictured), John Dory, snapper, basa, jewfish, blue eye cod (trevalla), tilapia, cod, halibut, pollock, hake.
Bear in mind, the form of fish signifies that you get thick cuts from the principle physique in addition to skinny cuts from in the direction of the tail. Go for the thicker cuts!
Fish to keep away from
I like to recommend avoiding:
Fish that dry out simply when cooked – Like swordfish, tuna, bonito, kingfish, marlin, mackerel. Except you’re extraordinarily cautious they’ll change into dry inside so are very susceptible to overcooking within the oven. I really feel these fish are (largely) higher in uncooked/uncommon kind equivalent to Ceviche, Poke Bowls, Tartare (additionally see Tuna Steak);
Oily, “fishy” fish – Like mullet and sardines (attempt this recipe for sardines!).
For the potato gratin and creamy sauce
And right here’s what you want for the remainder of the dish:

Potatoes – Floury (starchy) and all-rounder potatoes work finest to realize a beautiful potato gratin flavour.
– Australia: a budget dirt-brushed potatoes bought all over the place (referred to as Sebago) are best
– US: Russet
– UK: Maris PiperLeek – Flavour base for the gratin. Be happy to substitute with a regular onion!
Garlic – Flavour base.
Chardonnay or different dry white wine – This offers the sauce depth of flavour. With out, it tastes extra one dimensional and prefer it’s lacking “one thing”. Chardonnay is my favorite however any dry white wine that’s not too candy or too woody will work high quality. Non alcoholic substitute – Extra vegetable inventory.
Vegetable inventory/broth – For semi braising the potatoes in a flavoured broth, tastier than utilizing simply water!
Butter – For pan sautéing the potatoes earlier than ending them off within the oven.
Panko, parmesan and olive oil – The crunchy topping!
Easy methods to make Creamy Fish on Potato Gratin
This can be a one pan meal that begins off on the range and is completed within the oven. It will be useful if the entire dish may simply be completed within the oven however the taste in the long run result’s simply not nearly as good. Whereas utilizing the stove-to-oven methodology makes it firm worthy good!

Crunchy topping – Combine the panko and olive oil collectively, then stir by the parmesan.
Sauté the leeks and garlic, then prepare dinner the sliced potatoes for six minutes or till they’re partially cooked. Throughout this step, the potatoes take up the flavour of the leek and garlic which is what makes the gratin so good!
Braise the potatoes firstly in wine for 1 minute (simmer quickly to virtually absolutely cut back to prepare dinner out the alcohol) then the vegetable inventory for 1 1/2 minutes till diminished by half.
High with fish items (which we first sprinkle with salt and pepper). Then pour over the cream, aiming for as a lot protection as potential.
Topping – Sprinkle your entire floor with the crunchy topping.
Bake for half-hour – I PROMISE THE FISH DOES NOT OVERCOOK!! You’ll suppose it does, however it doesn’t. All that creamy goodness beneath the breadcrumb topping retains every little thing moist and succulent!
Broil/grill 4 minutes – Then to complete it off, I like to offer it a fast 4 minute blast beneath the oven grill/broiler to offer the topping pretty color.
Relaxation 5 minutes – Place on the counter and let it relaxation for five minutes earlier than serving. Don’t skip this step! That is when the juices within the fish will get reabsorbed into the fibres so whenever you reduce into the fish, it stays within the fish flesh (and results in your mouth) reasonably than operating out onto the plate.


What to serve with Creamy Fish on Potato Gratin
All it’s good to end off this meal is a contemporary, crisp salad to serve on the aspect. Simply toss leafy greens in French Dressing, or in the event you’re cooking for firm, attempt the French Bistro Salad. On theme with the French-ish vibes occurring on this dish!
I additionally wouldn’t say no to some crusty bread for mopping the plate clear. And for dessert – anybody for a pile of contemporary baked Madeleines? Quick turning into a go-to for dinner events as a result of the batter is made upfront (you may even freeze it!) and saved in piping luggage or jugs. Then it actually takes 2 minutes to pipe into the pan and 10 minutes to bake. How good is that!!! – Nagi x
