Tips for Making Baked Fish in Tomato Mushroom Sauce

Fish is a very delicate but robust source of protein. It’s best to always handle all fish in recipes with care, whether they are oven baked, pan seared, or grilled. These handy tips will help you learn how to cook fish in the oven with a scrumptious tomato mushroom sauce:

  • Make sure to properly defrost your fish to get the very best results for this recipe. To defrost it more quickly, you can place the fish in a bowl of cold water with 3 to 4 tablespoons of salt. It will defrost in a couple of hours.
  • Marinate the fish fillets in salt and lemon before cooking for firmer flesh, a fresh taste, and to make it easier to handle. You can also soak your fish in water with vinegar before baking, to make it sweeter, more tender, and so it could hold its shape better.
  • When you’re ready to bake the fish, place it on a bed of onions, celery, or both. This makes the fish stay in one piece when removing it from the baking dish and gives it extra flavor.
  • While cooking fish, tuck any thin ends underneath so it cooks evenly. The fish is done when it is opaque all the way through, or when you can easily flake the flesh at its thickest point with a fork.
  • Because tomatoes vary in acidity, you may need to add 1 teaspoon of sugar to balance the flavors of your tomato sauce for fish.
  • To thicken your sauce, cook it longer until it reduces. Reducing helps boil off some of the liquid, leaving you with a thicker sauce.
  • Fixing a thick sauce is much easier than fixing a thin sauce. Slowly stir in more broth until desired consistency is reached. Make sure not to overdo it, or you’ll have to cook it longer to re-thicken it.

Commonly Asked Questions

 Do you turn the fish over in the oven when baking?

The general rule with baked fish is to bake it for 10 minutes for every inch of its thickness. Unless the fish is an inch or less thick, you should turn it halfway through the cooking time.

What do you eat with baked fish?

Since this dish already has a lot of flavors, you’ll want to pair it with something that’s not too overpowering.
