Homemade Gravlax: Easy 24-Hour Cured Salmon with Fennel

Jump to Recipe Jump to Video Print Recipe

This homemade gravlax is based on my YouTube video, with a few adjustments since publication to make the proportions clearer and easier to reproduce at home. In the original video, I season by eye, which works when you have made the dish many times, but for a written recipe I prefer to give more precise salt and sugar guidance so the salmon cures properly without becoming too salty.

Gravlax is salmon cured with salt, sugar, herbs, and spices. It is not cooked with heat, so the texture stays silky and fresh, while the cure firms the fish just enough to slice it thinly. I make this version when I want a cold salmon appetizer that feels a little special but does not require cooking, smoking, or a complicated sauce.

The reason this recipe works is the light cure. The salmon sits on paper towel, gets wrapped tightly, and rests in the refrigerator for 24 hours. What I look for here is a salmon that is slightly firmer on the surface, still glossy, and easy to slice thinly without falling apart. The mistake to avoid is burying the fish under too much salt. Gravlax should taste clean and seasoned, not like a mouthful of seawater.

This version is different from my cooked salmon recipes. If you want a hot dinner, make pan-seared salmon or oven-baked salmon. If you want a richer bistro-style plate, salmon with beurre blanc is the better direction. This one is cold, thinly sliced, lightly cured, and made more for an appetizer board, brunch plate, holiday starter, or summer seafood platter.

What Makes This Gravlax Different

Classic gravlax is often made with dill, salt, sugar, and sometimes a little pepper. I use fennel here because it gives the salmon a soft anise flavour without taking over. It is delicate, a little floral, and very good with lemon, capers, red onion, and cream cheese.

I also add lemon pepper and a small amount of paprika-chili mix. Not too much. The salmon should still look like salmon. If the entire surface is hidden under a thick layer of spices, it becomes harder to control the cure and the flavour gets muddy.

I make it this way because I prefer a clean slice of cured salmon where you can still taste the fish first. The fennel comes after. The pepper comes after. The salt should support everything, not dominate.

This is also not the same as beet-cured salmon gravlax, which has a deeper colour and a more dramatic presentation. This recipe is simpler, lighter in appearance, and closer to the way I prepare a quick house-style cured salmon for a cold platter.

Important Raw Fish Safety Note

Gravlax is cured, but it is not cooked. Use very fresh salmon that was previously frozen or sold specifically for raw or cured preparation. Ask the fishmonger if the salmon has already been frozen and if it is suitable for raw-style preparations.

Keep the salmon refrigerated the whole time. Do not cure it on the counter. Once sliced, keep it cold and serve it the same day or within the next day for the best texture.

I prefer skin-on salmon for this because the skin makes slicing easier. You can cut thin slices down toward the skin and leave the skin behind on the board.

Ingredients You Need

For the salmon, you need a skin-on salmon fillet, salt, sugar, crushed fennel seeds, lemon pepper, a little paprika-chili mix, and fresh fennel fronds.

The sugar is an adjustment from the video. I add it because it balances the salt and gives the cured salmon a rounder, smoother flavour. It does not make the fish taste sweet. It just softens the cure.

The lemon pepper should ideally be salt-free. If your lemon pepper already contains salt, reduce the added salt a little. This matters because different seasoning blends vary a lot, and too much hidden salt is one of the easiest ways to ruin homemade gravlax.

For serving, I like black bread, rye bread, or a simple toasted slice of homemade bread. If you are making a seafood board, slices of homemade white bread work well, and a small loaf of crusty air fryer bread is also a good option if you want something warm on the side.

How to Make Gravlax

Start by checking the salmon. Remove any pin bones with tweezers and trim off thin uneven edges if needed. Pat the fish dry. Moisture on the surface makes the cure slide around, so take a few seconds here.

Place a double layer of paper towel in a small tray or dish, then set the salmon on top, skin side down. The paper towel helps absorb liquid as the salt pulls moisture from the fish. I prefer this to letting the salmon sit directly in the liquid, because the bottom stays cleaner and the texture is more controlled.

Mix the salt, sugar, crushed fennel seeds, lemon pepper, and paprika-chili. Sprinkle the mixture evenly over the flesh side. At this point, it should look seasoned but not buried. You should still see the orange colour of the salmon through the cure.

Add the fennel fronds on top, then wrap the salmon tightly with plastic wrap. Press it gently so the cure is touching the fish. Refrigerate for 24 hours. For a thicker center-cut piece, 30 to 36 hours is fine, but for this lighter version I usually stay around 24 hours.

After the cure, unwrap the salmon and remove the fennel. Gently scrape or brush away the excess seasoning. I prefer not to rinse unless the surface looks heavily salted. If you rinse, the salmon can take on water and lose some of that clean cured texture. A dry paper towel is usually enough.

Place the salmon on a cutting board. Use a long sharp knife and slice thinly on a bias, cutting down toward the skin. You know the texture is right when the slices hold together but still look silky and slightly translucent.

How to Serve It

I like this with cream cheese, capers, red onion, lemon, radishes, and a little mesclun. It gives you fat, salt, acidity, crunch, and freshness in one bite.

For a simple plate, spread cream cheese on rye or black bread, add a few slices of gravlax, then finish with capers and very thin red onion. A small squeeze of lemon wakes everything up. Do not drown it in lemon juice. The salmon is delicate.

For a larger seafood starter, serve it beside crispy crab cakes with lemon mayo, scallops with lemon butter, or lemon butter baked cod. Those are cooked dishes, so they give a nice contrast to the cold cured salmon.

A small salad is enough on the side. I like the freshness of a 10-minute mesclun salad with this, especially if the gravlax is served as a starter. A crunchy red endive salad also works because the bitterness cuts through the richness of the salmon and cream cheese.

Substitutions

Dill can replace fennel fronds if you want a more classic flavour. Use a generous handful and keep the fennel seeds out if you want the profile to be cleaner and more traditional.

Orange zest can replace lemon pepper. Use a light hand. A little citrus aroma is nice, but too much zest can make the cure taste perfumed.

Brown sugar can replace white sugar. It gives a slightly warmer flavour and a darker surface. I would not use maple syrup here because it adds liquid and can make the cure messy.

If you do not have paprika-chili mix, use a tiny pinch of smoked paprika or mild chili flakes. The goal is background warmth, not spicy salmon.

Cream cheese is classic for serving, but crème fraîche, sour cream, or a small spoon of homemade mayonnaise can work on a seafood platter. For a sharper sauce, a little homemade tartare sauce is better with cooked fish, but it can sit beside the gravlax if the platter has cod, crab cakes, or shrimp.

FAQ

Can I make gravlax without sugar?

Yes, but I prefer to use sugar because it balances the salt and makes the cure taste smoother. Without it, the salmon can taste sharper and more salty, even if the amount of salt is not extreme.

Can I cure the salmon longer than 24 hours?

Yes. A thicker piece can go 30 to 36 hours. The longer it cures, the firmer and saltier it becomes. For this version, I like 24 hours because the texture stays soft and delicate.

Should I rinse the salmon after curing?

Usually, no. I prefer to gently scrape or wipe off the cure. Rinsing can water down the surface and soften the texture. If the salmon looks heavily coated or tastes too salty at the edge, a quick rinse is possible, but dry it very well afterward.

Can I freeze gravlax after curing?

It is better fresh. You can freeze it, but the texture may become softer after thawing. For the best result, cure only what you plan to serve within a day or two.

What does gravlax taste like?

It tastes like fresh salmon with a firmer texture, gentle saltiness, and herbs. This version has fennel, lemon pepper, and a very light warmth from paprika and chili.

Is gravlax healthy?

Salmon is naturally rich in protein and fat, and this recipe is served cold without frying or a heavy sauce. It is still a cured food, so it contains salt. I keep the seasoning controlled so the finished salmon tastes balanced.

What to Serve With Gravlax

For a cold starter or brunch plate, serve the cured salmon with bread, cream cheese, capers, red onion, lemon, radish, and greens.
