Cod With Leeks and Tomatoes


Cod is a lean fish that is available year-round and can be baked, broiled, or poached. Its mild taste pairs well with sharp flavors, such as lemon.

  • 2 medium leeks, white and light-green parts only, thinly sliced, rinsed well, and patted dry
  • 2 tablespoons fresh lemon juice
  • 1 tablespoon olive oil
  • 1 teaspoon freshly grated lemon zest
  • 3 sprigs thyme, or 1 teaspoon dried thyme
  • Salt and fresh ground pepper
  • 2 1/2 cups cherry tomatoes (about 12 ounces)
  • 4 cod fillets, each 6 to 8 ounces and 3/4 to 1 inch thick


  1. Preheat oven to 450 degrees. In a 9-by-13-inch baking dish, toss together leeks, lemon juice, oil, lemon zest, thyme, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Cover with foil, and bake until leeks just begin to soften, 8 to 10 minutes.

  2. Remove baking dish from oven. Add tomatoes, and toss to combine. Season both sides of cod fillets with 1/2 teaspoon salt and 1/4 teaspoon pepper; place on top of vegetables.

  3. Cover dish and bake until fish is opaque throughout, about 15 to 20 minutes. Serve immediately.

Cook's Notes

Cut away and discard the root and dark-green leaves of the leeks, then thinly slice the white and light-green parts crosswise into rounds. Wash the pieces in several changes of cold water until there's no more grit at the bottom of the bowl. Drain on paper towels.

    Such a healthy and delicious recipe. I've also made it with sliced fingerling potatoes and chopped wax beans. Roast them first for 8-10 mins with olive oil and herbs, then proceed with the leeks. You can make this with chopped fresh summer tomatoes too.

    If you're thinking of making this recipe, you should! I've made it several times. It's so easy and very fresh tasting with the lemon and thyme. The leeks are quite mild and I love how the cherry tomatoes get plump and sweet after cooking (I actually used a carton of grape tomatoes). I served it with a green salad and orzo mixed with spinach and parmesan.

    I did not make any adjustments to the recipe above and was so dissapointed with the results. I will try making it without the thyme next time.

    I forgot the thyme, and it sounds like it's a good thing I did. Easy, light, yummy way to prepare fish and veggies. Tip: Trader Joe's sells leeks trimmed and washed in a two-pack bag. Makes this dish even easier.

    I thought this was really good. The thyme was a little strong, but my husband loved it. I used dried thyme, and I think I would try with the fresh next time for better flavor. The fish was mild enough that the kids ate it too. We will definately make it again.

    I did not care for this recipe. The thyme and leeks were a little much.
