I love poaching salmon because it keeps the fish both tender and moist. The problem is, that by submerging the salmon in water, you end up losing flavor in the poaching liquid. That’s why vacuum sealing the fillet in a bag and cooking it sous vide is such a great solution. You get melt-in-your-mouth salmon without watering down the flavor.
But cooking sous vide has its own set of drawbacks, the most obvious one being that many people don’t have a sous vide setup at home. Also, when you’re dealing with large pieces of fish (like a whole fillet of salmon), it’s tough to find a bag and chamber vacuum large enough to accommodate it.
That’s why I developed this method of poaching salmon in a regular oven set to a low temperature. By wrapping the fillet in foil, you’re not constrained to the size of vacuum bags. This allows the salmon to slowly poach in its own juices, making it incredibly tender and moist, without giving up any flavor.
The sauce is a light citrusy salsa verde made with cilantro, parsley, lemon juice, garlic and olive oil. It’s a perfect accompaniment for summer, and if you love cilantro, you’ll want to drink this sauce. Even if you’re not a big fan of cilantro, this sauce may just change your mind. That’s because it’s mixed with flat-leaf parsley, which pulls back the floral flavors of cilantro that some people consider “soapy”
Topped with some big cubes of avocado, this is a rich creamy dish that still keeps things light enough to be served on a hot summer day. Serve it hot, or chill the salmon for a delightful brunch entree that can be served with a salad. If you plan to make the sauce ahead of time, blend all the ingredients except the lemon juice together, as the acid will change the color of the sauce. Then, when you’re ready to serve it, just whisk the lemon juice in.
Ingredients
- 680 grams salmon (1/2 a whole salmon)
- 2 tablespoons olive oil
- 3 cloves garlic (grated)
- 1 lemon
- 1 teaspoons ground coriander
- 1/2 teaspoon salt
- ground black pepper
- 30 grams cilantro
- 20 grams flat leaf parsley
- 1/4 cup extra virgin olive oil
- 1 clove garlic
- 1/2 teaspoon salt
- 1/4 teaspoon ground white pepper
- 1 avocado (pitted, peeled and cut into cubes)
Steps
- Move the oven rack to the middle position and preheat to 250 degrees F (120 C).
- Cut a large piece of foil that's about four times the width of your salmon fillet, and a few inches longer. If your foil is not long enough, you may need to join a few sheet together by lining the edges up and folding them over a few times.
- Scale and debone your fillet and then use paper towels dry the surface of the fish.
- Rub 2 tablespoons of olive oil on both sides of the salmon and place the salmon skin-side down on the foil.
- Rub in the 4 cloves of grated garlic and sprinkle with the lemon zest, coriander powder, 1/2 teaspoon of salt and pepper.
- Fold the aluminum foil up and over the salmon and seal the top by folding down the top edge 3 or 4 times.
- Fold the left and right sides of the foil 3 or 4 times to make a package and place the package on a baking sheet.
- Bake the salmon for 25-30 min or until thermometer reads 135 F (57 C).
- To make the sauce, add the cilantro, flat-leaf parsley, 1/4 cup olive oil, 3 tablespoons of lemon juice, 1 clove of garlic, 1/2 teaspoon of salt, and white pepper to a small food processor or blender. Process until smooth.
- Cut the avocado in half lengthwise, and then remove the pit, and peel. Cut the avocado into 1/2" cubes and then toss with a little lemon juice to keep it from oxidizing.
- To serve the salmon, you can unwrap it and cut it up into portions or transfer it whole onto a serving platter. Drizzle some sauce on and around the salmon and scatter the avocado on top.
