POTATO-CRUSTED SALMON FILLETS
Potato-Crusted Salmon Fillets
- • 2 8-oz salmon fillets, approx 1" thick, skin-on
- • 3 tbsp olive oil
- • 1 medium russet potato
- • 2 tbsp Dijon mustard
- • 2 tbsp mixed herbs, chopped fine
- • Kosher salt and freshly-cracked black pepper, to taste
1. Preheat oven to 450F. Heat oil in a 12" oven-proof skillet over medium heat.
2. Peel and grate russet potato. Place grated potato on a clean kitchen towel or double-layered piece of cheesecloth; gather up the edges of the towel and squeeze grated potato to remove excess moisture. Set aside.
3. Pat dry salmon fillets. Season with salt and pepper. With skin-side down, spread a thick, even layer of Dijon mustard on each fillet. Sprinkle with herbs. Place a handful of grated potato on each fillet, spread to cover, and press down to make the potato adhere to the Dijon mustard. Sprinkle again with salt and pepper to taste.
4. Place the salmon fillets potato-side down in the skillet. Do not move. Cook until potato crust sets up and begins to pull away from the skillet, about five minutes. Using a thin spatula, work your way underneath the salmon fillets and carefully flip over, skin-side down.
5. Place skillet in oven, uncovered, and let cook through, five minutes. Remove skillet from oven, plate salmon and serve.
If you are prepping ahead of time, the potato can be grated and placed into a container of cold water up to 2 hours ahead of time. This will prevent the potato from turning brown and developing off flavors, but it will also remove much of the excess starch in the potato that is useful in making a hash-brown-crisp crust. If using this method, watch the fillets carefully while on the stove top to make sure the potatoes aren’t burning or sticking. But don't fuss with them - if you keep trying to move the fillets, you'll wind up with a soggy, torn mess.
You want to use russets, as their high-starch content will make for a better crust. Thicker fillets are better here, as they will be less likely to dry out. This is a very fast-cooking recipe, but because you’re looking for the potatoes to get crisp, it requires a fairly high heat. In addition, using skin-on fillets will also help retain the moisture. The skin acts as a barrier between the hot pan and the fish while in the oven. When removing the fish from the pan, the skin will most likely stick; just slide the fillet off of it and serve without the skin.
Toss some asparagus in a little bit of olive oil, spread on a sheet pan, and pop them into the 450F oven for 8 minutes or so right before you put the fish into the skillet. Pull them out when you put the fish into the oven. Instant side dish with virtually no effort.
