San Francisco Swordfish Cakes with Spicy Brown Mustard Mascarpone

July 16, 2010

Author Notes: The best crab cakes, and sourdough bread I've eaten, have been in San Francisco. So that's what I pictured when I set out to create this swordfish recipe. Cute lil' cakes that were crispy on the outside, while keeping moist and flavor packed on the inside. The swordfish cakes were a great hit! I loved hearing responses from non-fish eater, "WOW, this is perfect." Note: Making sourdough breadcrumbs is a great way to use unwanted, not-so-fresh sourdough! Merry

Serves: 6 cakes


  • 3 to 5 slices sourdough bread
  • 2 tablespoons finely grated Parmesan cheese (canister not fresh)
  • 1/2 teaspoon lemon pepper seasoning
  • 2 green onions
  • 2 celery sticks, (1/2 cup chopped celery)
  • 1 teaspoon fresh thyme
  • 1 clove garlic
  • 1 teaspoon lemon zest
  • 1.5 pounds swordfish, rinse, pat dry, cut 1-inch chunks
  • 2 teaspoons tamari sauce
  • 1/2 teaspoon sea salt
  • 1 egg white
  • 2 tablespoons light tasting olive oil
  • 4 ounces Mascarpone cheese, soften
  • 2 tablespoons Spicy Brown Mustard

In This Recipe
