What You'll Need
  • 1 large garlic clove
  • 1/2 cup shelled walnuts
  • 2 tablespoons Gourmet Garden Lightly Dried Chives or fresh chives
  • 2 tablespoons Gourmet Garden Lightly Dried Basil or fresh basil
  • 3 tablespoons grated parmesan cheese
  • 6 sprigs fresh thyme (about 1 TB)
  • 1 tablespoon extra virgin olive oil (or garlic-infused olive oil)
  • 1/4 teaspoon sea salt (or as needed)
  • 1/8 teaspoon ground black pepper
  • 4 pieces cod (6 oz. each), fresh or thawed
  • 1/4 teaspoon sea salt (or as needed)
  • 1/4 teaspoon ground black pepper
  • 1/2 tablespoon extra virgin olive oil
  1. Preheat oven & make the gratin. Preheat the oven to 375 degrees F. In a small food processor, blitz the garlic until minced. Add the nuts and herbs and pulse until the texture is a coarse, crumb-like texture. Next, add the cheese and pulse until just combined. (Do not over pulse to avoid making the mixture pasty). Dump the mixture into a small bowl and add the olive oil, salt, and pepper. Mix well.
  2. Pat the cod dry with a paper towel. Place the fish pieces into a baking dish and season them with salt, pepper, and olive oil. Top each piece with a couple of spoonfuls of the gratin mixture.
  3. Place the dish on the middle oven rack. Bake for 9-15 minutes or until the internal temperature of the fish is at least 145 degrees F and the gratin is lightly golden brown. Serve with salad and enjoy!

Parmesan cheese and fish! On my first trip to Italy (Europe on $5 a day) I was practically thrown out of a (very "affordable") restaurant in Rome because I asked for cheese for my fish. I'm not worried about being thrown out -- older and wiser -- but I have to agree. Not a great combination.

Sometimes rules are meant to be broken when it comes to food. In most cases, I would agree that cheese is not the best accompaniment to fish. However, in this case, I think the herbs provide a pleasant balance to the parmesan. It never hurts to try something unconventional.
