I used to fish a lot when I was younger and catching some lake trout and cooking them for dinner was a real treat of mine.

I recently found some trout fillets at my local grocery store.  Since trout has long been one of my favorite types of fish, I was delighted to cook them for dinner.

However, when I opened the package, I discovered that the fillets were very thin which meant they were likely to come apart in a frying pan if I tried to pan fry them. What to do I asked?

I recently wrote a post about cooking fresh fish and read over it to get some ideas.

Time for some Panko bread crumbs, fresh Parmesan cheese and my oven!

Normally, when I do a recipe for coated trout, I use an egg and milk mixture to coat the fish before applying bread crumbs and lightly pan fry them. Today, I chose to give the fish some extra flavor by coating them in a mixture of light Mayonnaise, lemon zest and Dijon mustard.Lemon zest, mayo, Dijon mustard and trout fillets

I’ll use the oven instead of oil on the stove to keep the calories lower and make the dish lighter in taste.

Making these Oven Baked Trout Fillets

I started by combining the mayonnaise, lemon zest, and some minced garlic in a small bowl. The marinade/coating will give an extra boost of tangy flavor to the fish and help to keep them moist and flaky.marinade coating for fish

This tangy citrus mixture will get spread on both sides of the trout fillets to give the bread crumbs something to stick to.

I love adding fresh herbs to almost any recipe. The flavor of them is so much more intense than dried herbs. Fresh thyme gets combined with the Panko bread crumbs and grated fresh Parmesan cheese to make the coating for the fish.Fresh Parmesan cheese, Panko bread crumbs and fresh thyme

Use fresh Parmesan cheese if you have it instead of the bottled kind. Not only is the flavor better but it helps to crisp up the Panko as the fish cooks.

Spread the mayo/mustard mix on the fish and roll the seasoned trout in the Panko mixture to coat evenly. Be sure that both sides of the fish are coated and spread with the mustard seasoning.Coating the fish for baking

Place the prepared trout fillets in an oven proof baking dish that has been sprayed with cooking spray and give the top of the fillets another spray of the cooking spray to help them crisp up in the oven.Trout seasoned with Panko, ready to bake

Baking a trout does not take long, especially if the fillets are thin like these. Place the prepared fillets in the preheated 425 º oven for 12-15 minutes or until fish begins to brown and flakes lightly.Baked rainbow trout

Other ideas for cooking thin fish fillets

Have you noticed that if you buy fish at the grocery store in larger packages that they are usually very thin? This makes a normal pan sear almost impossible. Here are a few ways to enjoy the taste and have the fish hold together well.Tips for cooking thin fish fillets

  • Spread the fish with a moist mixture and coat in Panko and bake. I used mayo and mustard, but there are lots of other possibilities.  Yogurt makes a good tangy base.  Hummus adds some fiber.  Think outside the box about how to season the fish before adding the Panko.
  • Do a fish fry. Beer batter and other fried fish batter will hold the fish well without it falling apart.
  • Lay the fish on parchment paper with some lemon, butter and vegetables and fold the paper papillote style to encase the fish and keep it moist and tender.
  • Think outside the box when it comes to coating the fish if you plan to oven bake or pan fry it. I used Panko today, but seasoned Italian bread crumbs, ground nuts and coconut also works well.
  • Instead of trying to pan fry thin fish, use the broiler.  Try broiling it using a flat pan, not a rack. It will cook through without turning the fish.
  • Poached fish gives a lovely flavor to thin fillets. Use hot milk with fine chopped spices. It cooks in just a few minutes!
