Torsk i Fad med Bacon og Bløde Løg

Ingredients

Equipment Needed

• •Shallow oven dish (fad), approximately 25cm by 35cm
• •Heavy frying pan
• •Slotted spoon

Instructions

1. 1

   Season the cod

   Pat the cod fillets thoroughly dry with kitchen paper. Season them on both sides with fine sea salt and white pepper. Set them aside on a clean plate while you prepare the rest. Drying the fish matters: wet fish steams instead of baking, and you want the surface to firm up gently in the oven's heat, not release water into the cream.

   Choose thick-cut fillets from the loin end if you can. Thin tail pieces overcook before the breadcrumbs have time to go golden, and the whole dish loses its balance.
2. 2

   Render the bacon

   Place the bacon lardons in a cold, dry frying pan. Set it over medium heat and let the fat render slowly. This is not a quick fry. Starting cold draws the fat out gradually, which gives you lardons that are crisp all the way through, not burnt on the outside and soft in the middle. Stir occasionally. After eight to ten minutes, when the lardons are golden and the pan holds a good puddle of clear bacon fat, lift them out with a slotted spoon and set them on kitchen paper. Keep every drop of that fat in the pan.

3. 3

   Soften the onions

   Add a knob of butter to the bacon fat in the pan and let it melt. Tip in all the sliced onions and a pinch of salt. Stir them through the fat, drop the heat to low, and put a lid on. Now leave them alone. Stir every few minutes. The onions need fifteen minutes at least, probably closer to twenty, until they are completely soft, sweet, and golden. They should look like they've given up any resistance. This is the step that makes or breaks the dish. Bløde løg means the onions have no bite left in them at all. They become a sweet, silky bed for the fish, and if you stop too early, that sweetness never develops. When a spoonful of onion tastes gentle and almost jammy, they're done.

   If the onions start to catch or brown too quickly, add a splash of water and stir. The steam brings the temperature back down. You want slow gold, not fast char.

   Butter the fad

   Heat the oven to 200°C. Rub the inside of a shallow oven dish, your fad, generously with soft butter. Every surface, sides included. The butter serves two purposes: it prevents the fish from sticking, and it adds richness to the sauce that forms when the cream meets the onion juices and the heat of the oven. A fad about 25cm by 35cm is the right size for four pieces.

5. 5

   Assemble the dish

   Spread the soft onions across the bottom of the buttered fad in an even layer. Tuck the bay leaves in among the onions. Lay the seasoned cod pieces on top, spacing them so they don't touch. Scatter the crisp bacon lardons over and around the fish. Pour the cream slowly over everything, letting it find its own level. The cream should come about halfway up the fish, not cover it. That exposed top is where the breadcrumbs will brown.

6. 6

   Add the breadcrumb crust

   Scatter the coarse breadcrumbs evenly over the top of the dish, concentrating them on the fish itself. Melt the remaining butter and drizzle it over the breadcrumbs. The butter is what turns the crumbs golden and crisp in the oven. Without it, they dry out and turn pale and dusty. With it, they form a crust that shatters gently against the soft fish beneath.

   Coarse breadcrumbs give the best texture. If you can only find fine ones, use slightly less. Fine crumbs pack down into a dense layer instead of staying open and crisp.
7. 7

   Bake until golden

   Place the fad in the middle of the oven and bake for twenty-five to thirty minutes. You're watching for two things: the breadcrumbs should be deep golden, and the cream should be bubbling steadily at the edges of the dish. The fish is done when it flakes easily if you press the thickest piece gently with a fork. Cod overcooks quickly, so start checking at twenty minutes. The carry-over heat while you bring the dish to the table finishes the last degree of cooking.

8. 8

   Rest and serve

   Let the fad rest on a trivet for five minutes once it's out of the oven. The cream calms down from a rolling bubble to a gentle simmer and thickens slightly as it cools. Scatter the fresh dill over the top. Serve directly from the fad, spooning the onions and cream sauce from underneath alongside each piece of fish. Boiled potatoes belong next to this, nothing more. Tak for mad.

Chef Tips

• •Buy your torsk from a fishmonger you trust, or from the freshest source you can find. The fish should smell of the sea and nothing else. If the cod isn't good, don't make the cod dish. A piece of firm, translucent fillet is what you're looking for.
• •Don't rush the onions. I know I've said it already. I'm saying it again because this is the mistake that ruins the dish. Twenty minutes feels like a long time when you're standing at the stove, but those last five minutes are when the onions go from cooked to transformed.
• •Some cooks add a tablespoon of Dijon mustard to the cream before pouring it over. It's not traditional, but it adds a quiet warmth that works with the bacon. If you try it, stir the mustard into the cream while it's still cold. Mustard that hits direct heat turns bitter.
• •This dish reheats well the next day. Cover the fad with foil and warm it in a 160°C oven for fifteen minutes. The breadcrumbs won't be as crisp, but the flavors deepen overnight.

Advance Preparation

• •The dish can be assembled completely, covered with cling film, and refrigerated for up to six hours before baking. Add five minutes to the baking time if it goes into the oven cold.
• •The onions can be softened the night before and kept in the fridge. Bring them to room temperature before assembling so they don't chill the fish.
