Baked Stuffed Fish Fillets

stuffed fish

My son created this dish and we worked on it together to create a spicy dinner the entire family loved. We used flounder fillets, but tilapia or any white fish should work well. It also can be made ahead, it reheats beautifully. It was his idea to serve it with the hasselback potato that we added grated Parmesan to and he called it his version of Fish ‘n Chips.

In a medium sauté pan over low heat, add the oil; add half the onion and a pinch of salt and sweat until translucent. Add 1 clove of garlic and continue to cook for another minute. Add the spinach and cook until just heated through. Season with the salt and pepper, add the breadcrumbs and the cheese and stir to combine. Remove from the heat.

If the fillets are large, cut in half. Season each filet on both sides with salt and pepper. Divide the spinach mixture evenly among the fillets and roll the fish around the mixture. Place fish rolls in a baking pan seam side down.  Bake in preheated oven for 25 minutes.

Meanwhile, prepare the sauce: Place a saucepan over medium heat.  Add the other 1 tablespoon olive oil, other half of the onion and garlic.  Saute 5 minutes, until fragrant.  Add tomatoes and cook for about 5 minutes, adjust salt and pepper to taste add Half and half and remove from heat.  Keep warm until ready to use.

Note:  You can use the sauce as is or if you are like my son and you don’t like chunks of tomatoes you can puree it.
