Growing up in Louisiana, seafood was often on our dinner table. Being so close to the Gulf meant we were always able to get fresh seafood pretty much all the time. This easy baked catfish recipe is inspired by the wonderful seafood dishes I grew up loving back home.

See recipe box below for ingredient amounts and full recipe instructions.

  • fennel
  • olive oil
  • red pepper
  • onion
  • tomatoes
  • garlic
  • dried thyme
  • salt and pepper
  • white wine
  • catfish fillet

Do I Have To Use Wine?

No, you don't have to use wine. You can use broth or water instead.

Can I Use A Different Type Of Fish?

Yes! You don't have to use catfish. I've used cod, halibut, flounder and trout with success in this recipe.

How To Bake Catfish

This one dish meal is so easy to prepare.

  • I used fennel in this dish and I love the flavor it imparts. Fennel tastes a little like licorice and when it's cooked, it tastes a little sweet. The mild fennel is perfect with the catfish especially when mixed with red peppers, tomatoes and garlic.
  • The vegetables bake in one baking dish for about 20 minutes. After the vegetables cook, a little white wine is added to the pan before being topped with the catfish fillet.
  • The fish along with the vegetables bake in the oven for about 20 minutes longer.

In the amount of time it takes for the catfish to bake, you can bake a single serving of rice.

Baking rice is easy and the rice cooks perfectly every time. While the catfish cooks, so does the rice.

Ways To Use Leftover Ingredients

If you have any ingredients left over from this baked catfish recipe you might like to consider using them in any of these single serving and small batch recipes:


For this baked catfish recipe, I use a 1-quart dish for the catfish and a 5-inch dish for the rice. For best results, use a dish of similar size.
