Baked Haddock with Spinach and Tomatoes Recipe

Preheat oven to 375 degrees F (190 degrees C). Lightly butter a 2-quart casserole or baking dish large enough to hold haddock fillets in a single layer.

Melt 1 tablespoon of the butter in a skillet over medium heat and cook the onion slices stirring occasionally until soft about 5 minutes. Stir in spinach and nutmeg and cook for about 3 minutes.

Arrange haddock fillets in baking dish. Spoon equal portions of the spinach mixture between the fillets. Spoon drained tomatoes around fillets and sprinkle with the thyme tarragon and salt.

Bake uncovered for 20 to 25 minutes or until fish flakes easily with a fork.

While fish is baking make the sauce. If necessary add enough water to reserved tomato liquid to make 1 cup. In the skillet melt the remaining 1 tablespoon butter over medium heat. Stir in the minced onion and cook until soft about 5 minutes. Add 3/4 cup of the tomato juice to the onions. Bring mixture to a boil. Whisk the cornstarch into the remaining 1/4 cup juice then add to the skillet. Reduce heat and simmer stirring until sauce thickens slightly. Pour sauce over baked fillets and serve.
