Lemon Garlic Cod with Roasted Grape Tomatoes

Fresh cod baked with garlic butter, sweet grape tomatoes, and lemon, finished with fresh herbs.

This is a wonderfully simple way to prepare fresh cod, especially when using a thick, meaty king-cut fillet. The fish bakes gently in olive oil and garlic butter while the grape tomatoes soften, burst, and release their juices, creating a delicious sauce.

The lemon adds brightness, while a sprinkling of fresh parsley or cilantro gives the finished dish a fresh, colorful appearance. Served directly from the casserole or plated with seasonal vegetables, it makes an attractive dinner with very little preparation.


Serves 2

Prep: 10 minutes

Cook: 20–25 minutes

Ingredients

¾ lb thick-cut cod fillet (preferably king cut)

1 pint grape tomatoes

3 cloves garlic, minced

2 tablespoons olive oil, plus a small drizzle for the tomatoes

3 tablespoons butter, melted

1 small lemon, thinly sliced

A palmful of fresh parsley or cilantro, finely chopped

Salt and freshly ground black pepper, to taste



Preparation

Preheat the oven to 400°F (205°C).

Prepare the tomatoes. Place the grape tomatoes in a medium bowl and toss with a small drizzle of olive oil. Season lightly with salt and freshly ground black pepper.

Prepare the baking dish. Coat the bottom of a medium ceramic casserole with the 2 tablespoons of olive oil. Sprinkle half the minced garlic evenly over the bottom.

Arrange the fish. Pat the cod dry with paper towels and place it in the prepared casserole. Arrange the grape tomatoes around and over the fish. Season the cod lightly with salt and pepper.

Add the garlic butter and lemon. Combine the melted butter with the remaining minced garlic. Spoon the mixture evenly over the cod and tomatoes. Arrange several thin lemon slices over the fish, allowing a few to rest among the tomatoes.

Bake. Place the uncovered casserole in the preheated oven and bake for approximately 20–25 minutes, depending on the thickness of the cod. The tomatoes should soften and begin to burst, and the garlic butter should be bubbling gently. The fish is ready when it turns opaque and flakes easily with a fork. For food safety, the center should reach 145°F (63°C).

Finish and serve. Remove the casserole from the oven and scatter the chopped parsley or cilantro over the fish and tomatoes. Spoon some of the warm garlic butter and tomato juices over each serving.

Serve immediately with your favorite vegetables, rice, or potatoes.

Cook's Notes

  • The cod: A thick king-cut fillet is particularly suitable because it remains moist during baking. Begin checking after 15–18 minutes if the fish is not especially thick.

  • The tomatoes: Leaving the grape tomatoes whole allows them to roast gently and release their juices into the butter sauce.

  • The lemon: Thin slices soften as they bake and provide a pleasant citrus flavor. A little fresh lemon juice at the table is also excellent.

  • Serving suggestion: As shown in your photograph, steamed broccoli and fresh corn on the cob make an attractive, colorful accompaniment without competing with the delicate fish.

Umami Beef Short Ribs Samin Nosrat

This is the penultimate prep for beef short ribs.  Based on the superb documentary by Samin Nosrat, Salt, Fat, Acid, Heat, this is the most umami rib dish you will ever have.  Its the combination of red miso and soy sauce that marinates and flavors the beef - give it a long time to work right - that means overnight in the fridge; it's worth the planning ahead. 6 beef short ribs on the bone, about 3-4 lb 1 large sweet yellow onion, diced 2 stalks celery, diced 1 jalapeño pepper, minced 4 cloves garlic, halved Marinade: 1/4 cup red miso 1/4 cup soy sauce 1/4 cup pale dry sherry or Mirin rice wine 1 Tbsp sesame oil 1 Tbsp honey 2 cloves garlic, minced Salt the ribs generously with coarse salt and let rest overnight in the refrigerator in a resealable plastic bag.

Haddock Roasted with Aioli and Tomatoes

This is a simple yet suculent way to roast fish. Here I use haddock, but you could use most any fish including cod or tilapia, or as I did on the west coast, wild-caught Rockfish (delicious). The tomatoes offer a fresh flavor complement to the fish slathered with a rich aioli topping. This is a quick, easy way to prepare fish on a busy weeknight. 1-1/2 lb haddock fillet (Captain’s cut preferred - thicker), patted dry Aioli: 1/4 cup good real mayonnaise 1 tsp Dijon mustard 1 Tbsp favorite hot sauce 1 pint grape tomatoes 1/2 tsp dried dill weed Fresh parsley, minced, for garnish Lemon wedges for garnish Preheat oven to 375F. Oil a medium baking dish (about 7x10-inch). Lay haddock fillet in dish. Whisk together the mayonnaise, mustard and hot sauce in a small bowl. Using a pastry brush, cover the fillet evenly with the aioli sauce. Toss the tomatoes with a dash of olive oil and scatter them over the fish. Season with dill and freshly ground black pepper to taste. Bake fish for about 20 mi...

'Back-of-the-bag' King Arthur Oatmeal Bread

This is one of the best loaves of bread I have ever made, based on a famous recipe.  Friends swear about King Arthur recipes, and now I do too.  I only modified King Arthur's recipe slightly, adding the yolk of the egg I used for the eggwash on the crust. Goes great with a big pot of bean soup.  And it toasts up so nicely - aroma therapy for the whole house! 3-1/4 to 3-1/2 cups bread flour 1 cup old fashioned oats 2 tsp active dry yeast 2 Tbsp honey 1-1/2 tsp salt 2 Tbsp butter, finely diced 1 egg yolk 1-1/4 cup lukewarm (about 100F) milk 1 egg white plus 1 Tbsp water about 1/4 cup old fashioned oats for topping Mix ingredients to a firm but still tacky dough.  You’ll have to adjust the final amount of dough to the humidity of your kitchen and flour - err on the sticky side for a lighter, moister loaf.  Knead dough 5 minutes.  Roll dough around in an oiled bowl and cover with plastic wrap. Allow dough to rise an hour. ...
