Salmon with Tomato, Onions, and Capers

Salmon fillets poached in a tomato onion caper sauce with white wine.

  • Prep time: 15 minutes
  • Cook time: 30 minutes
  • Yield: Serves 4.


  • 3 Tbsp olive oil
  • 1 medium onion, chopped
  • 2 garlic cloves, peeled and diced
  • 2 large fresh tomatoes, diced
  • 1 Tbsp fresh thyme leaves, chopped
  • 2 teaspoon freshly grated lemon zest
  • The juice of one meyer lemon, or half a regular lemon with a teaspoon of sugar
  • 2 Tbsp of capers, drained
  • 1 teaspoon of chopped jalapeño peppers (no seeds, no stem, no ribs) either fresh or pickled
  • 1/3 cup white wine
  • 1/4 cup water
  • Salt and pepper
  • 2 fresh salmon fillets, 1/2 lb each


1 In a large, wide (at least 12 inches wide) saucepan (one that comes with a cover), heat olive oil on medium heat. Add the onion and cook, stirring regularly, until just beginning to brown, about 5 minutes. Add the garlic and cook for 1 minute. Raise the heat to medium-high and add the tomatoes, thyme, lemon zest, lemon juice, capers, and jalapeño peppers. Simmer for 10 minutes, adding a little water if needed to prevent the sauce from getting too dry. Salt and pepper to taste.

2 Add 1/3 a cup of white wine - a simple Chardonnay will work. Add 1/4 cup of water. Bring to a simmer. Place the fillets in the pan on top of the sauce, skin side down, if the fillets are still in their skin. Cover and reduce heat to medium-low. Cook for 5-10 minutes, depending on how thick the cuts of fish are. Poke the fish with a fork and look for doneness. The fish should still be somewhat rare in the middle, but not raw. Serve immediately, with tomato sauce generously applied.

  • Leea

    Made this for dinner guest, had a can of fire-roasted diced tomatoes and used instead of fresh. Everyone really enjoyed this dish.

  • Alicia

    I really enjoyed this recipe, I eat salmon all the time and this was a new, tasty way to prepare it. Even my 2 year old enjoyed it! Thanks!

    I really do love this recipe. I make it for all my guest.. I even made it once for one of my friends mother from Germany. and she loved it so much she begged me (hardly speaking English) for the recipe. she kept the left over tomato sauce from the salmon to put on a baguette the morning after. Thank you so much for this Recipe.

    This was wonderful. I made it for my family and my picky grandma was here and I was convinced she wouldn’t like it, she loved it! Thanks for the recipe

    This was great! I was looking for a last minute switch to salmon (from tri tip!) and of course checked here first! I had everything but the tomatoes so I used a can of diced and kept everything the same except didn’t add the water; excellent! Served with risotto in the pressure cooker and homemade bread and everyone raved! Thank you sooo much for all the raves I’ve been awarded since finding your site!
