Tomato Caper Sauce:

  • 1 tablespoon olive oil
  • 1 onion, diced
  • 2 garlic cloves, finely diced
  • 1 tablespoon capers or use diced Kalamata olives
  • 14 ounce can diced tomatoes or 1 lb fresh tomatoes, cored + diced
  • ½ teaspoon fresh thyme, removed from stems ¼ tsp dried thyme


  • 1 tablespoon olive oil, divided
  • 8 ounces lingcod (2 fillets) Or swap halibut, cod, or another dense white fish
  • teaspoon sea salt
  • ¼ lemon (4 thin slices)


Tomato Caper Sauce:

  • Add oil to a heavy saucepan over medium heat. Add diced onions and cook 3-5 minutes, or until the onions are tender.
    Add garlic and capers. Cook 1-2 more minutes, or until garlic is fragrant.
    Cook Onions Until Tender
  • Add tomatoes, salt, and thyme. Lower heat to medium-low, and simmer for about 10 minutes or until the sauce is thickened. (If your tomatoes are especially juicy, they may take a few minutes longer to cook.)
    Cover sauce to keep warm.
    Optionally, prepare the sauce up to 3-4 days ahead of time, and rewarm before serving.
    Add Tomatoes + Simmer Until Thickened

Baked Lingcod:

  • Preheat oven to 450°F.
    Brush an oven-safe pan with half the oil. Alternatively, use a baking sheet or casserole dish.
    Set the lingcod in the pan. Drizzle remaining oil over fish and sprinkle with salt. Cover the lingcod in lemon slices.
    Add Lingcod to Oven-Safe Pan
  • Cover pan with foil, and bake 8 minutes per 1" thickness. The fish is done when tender and easily pierced by a fork.
    Note that thinner fillets of fish will cook more quickly, so take care to note the thickness of the fillets.
    Bake Covered Until Tender
  • Serve the lingcod right away along with the tomato caper sauce.
    Any extra sauce can be used to top side dishes (such as rice, pasta, or cauliflower rice).
