You Will Love This Deliciously Easy Oven Poached Salmon
I love serving salmon when entertaining – most of our friends and family like it, plus it’s very versatile, easy to prepare, and super delicious. In fact, I have several recipes (including this one) where you can prepare it ahead of time, which I love because then I can enjoy my own party!
What is Poached Salmon?
Poaching is a cooking method in which food is gently simmered in a flavored liquid until it’s cooked through. This technique prevents the salmon from becoming dry, resulting in a moist and tender dish. Moreover, the seasonings in the liquid gradually infuse into the fish, creating a salmon dish with a subtly nuanced flavor.

How to Poach Salmon
In this recipe, a salmon fillet is topped with sliced lemons, onions, peppercorns and bay leaves, wrapped in cheesecloth, and then baked in white wine. The result is a light, flavorful, moist piece of salmon. I prefer oven poached salmon (vs. poaching on the cooktop) because I think it’s easier to control the temperature, and therefore you’re less likely to overcook it.
I was intimidated by poaching at first, until I tried poaching salmon in the oven and realized how easy it is! Here are the steps.
- Preheat oven.
Preheat oven to 350 degrees, with rack in middle.
- Prep cheesecloth.
Cut a piece of cheesecloth large enough to wrap the salmon fillet completely.
- Prep baking dish.
Spread cheesecloth in a glass baking dish (large enough to hold the salmon in one layer); the cheesecloth will extend out over the long sides of the pan.
- Prep seasonings.
Slice lemons and onions.
- Prep salmon.
Lay salmon fillet(s), skin side down, on cheesecloth. Spread lemon slices over top. Top with sliced onions. Scatter peppercorns over the top. Place bay leaves evenly on top. Fold over cheesecloth over salmon to cover completely; tuck in sides.
- Add poaching liquid.
Pour wine over the top of salmon.
Bake for 30 to 40 minutes, or until an instant read thermometer inserted in the thickest part of the fillet reaches around 125 to 130 degrees.
- Remove and cool.
Remove pan from oven. Using two large flat spatulas, carefully remove fish from pan and place on a cutting board to cool. Once cool, wrap salmon (still in cheesecloth) in plastic wrap and refrigerate.
To serve, remove cheesecloth and seasonings from salmon, keeping the lemon slices for garnish. Place fillet on a serving dish; arrange lemon slices over the top (see photo). Garnish with dill.
Note on how long to Poach Salmon
Cooking time may vary depending on the thickness of the fillet, as well as your preference for doneness. I always suggest checking the temperature 5 to 10 minutes before the time noted in the recipe (so, for this recipe start checking at around 20 to 25 minutes), especially if you have a thinner fillet.
What to Serve with Poached Salmon
So pretty, so scrumptious, this poached salmon pairs perfectly with this amazing sauce of grated cucumber, mayonnaise, sour cream, Dijon mustard, lemon juice, dill and chives. Whenever I prepare this sauce, I can’t stop eating it, so the recipe makes a bit extra, to ensure there is enough for Robert and our guests!
Here are some other suggested side dishes:
- Lemon Dijon Green Beans
- Roasted Tomato and Arugula Salad
- Lemon Rice
- Prosciutto Wrapped Asparagus
- Sautéed Asparagus
- Cranberry Pecan Couscous
Storing Poached Salmon
Store poached salmon well wrapped and in the refrigerator for up to 2 days. While it can be frozen, the texture and flavor will change, so I don’t recommend it.
Poached Salmon Recipe FAQs
I prefer poaching salmon in the oven, because it’s easier to control the cooking temperature. Burner temperatures are not as exact as ovens. And, controlling the temperature means you’re less likely to overcook it.
Yes you can. I actually prefer cooking my fillets with skin on because it helps hold them together. Once the salmon is cooked and becomes flaky, it can fall apart.
The best way to tell if any fish is done is an instant read thermometer. Once the middle of the thickest part of the salmon fillet reaches between 125 to 130, it’s time to take it out of the oven. It will continue cooking a bit as it cools.
Yes, salmon can be poached up to 2 days ahead, covered and refrigerated – but it’s best served within 12 hours of poaching.

- 2 large cucumbers
- 1 cup mayonnaise
- 1 cup sour cream
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh lemon juice
- 1/2 cup loosely packed fresh dill fronds (around 1 2/3-ounce package), chopped
- 1/4 cup chopped fresh chives
- 1/2 teaspoon kosher salt
- Fresh ground pepper, to taste
- 1 (3-pound) salmon fillet (see Variation)
- 2 lemons, thinly sliced
- 1/2 large yellow onion, thinly sliced
- 1/2 teaspoon black peppercorns
- 3 large bay leaves
- 2 cups dry white wine
- Fresh dill, for garnish
Cucumber Dill Sauce
- Peel, seed and grate the cucumbers. Place in a dish cloth, roll up and squeeze/ring out as much moisture as possible. Set aside.
- In a medium mixing bowl, whisk together the mayonnaise, sour cream, mustard and lemon juice. Stir in chopped dill and chives. Remove grated cucumber from cloth and stir into mayonnaise mixture, along with the salt and pepper.
- Cover and refrigerate for at least 30 minutes.
- Preheat oven to 350 degrees.
- Cut a piece of cheesecloth large enough to wrap the salmon completely. Line a glass baking dish large enough to hold the salmon in one layer with the cheesecloth. Lay salmon fillet(s) on cheesecloth.
- Spread lemon slices over top of salmon. Top with sliced onions. Scatter peppercorns over the top. Place bay leaves evenly on top. Fold over cheesecloth to cover completely and tuck in sides. Pour wine over the top. Bake for 30 to 40 minutes, or until an instant read thermometer inserted in the thickest part of the fillet reaches around 125 to 130 degrees.
- Using two large flat spatulas, carefully remove fish from pan and place on a cutting board to cool (takes around 30 minutes). Once cool, wrap in plastic wrap and refrigerate for at least 2 hours, up to 2 days.
- When ready to serve, remove cheesecloth, bay leaves, onions and peppercorns. Carefully remove lemon slices and set aside. With a damp paper towel, gently wipe off any white residue on top of salmon. (It’s coagulated protein and it’s fine to eat, it just doesn’t look pretty!) Using two large flat spatulas, move salmon to a serving platter.
- Wipe any white residue off of lemon slices; arrange decoratively on top of cooked salmon (see photo). Garnish with fresh dill. Place cucumber sauce in a bowl and serve on the side.
Variation: Instead of one large fillet, substitute 6 to 8 individual fillets. Reduce cooking time to 15 to 20 minutes.
Make ahead: Cucumber sauce can be made up to 2 days ahead, covered and refrigerated. Salmon can be poached up to 2 days ahead, covered and refrigerated – but it’s best served within 12 hours of poaching.
