Baked Whole Catfish
This baked whole catfish is the recipe my family requests more than anything else on my blog, and once you taste that herb and pepper marinade stuffed right into the fish, you’ll completely understand why. I’m going to show you exactly how to get a whole catfish perfectly tender and juicy in the oven, no fancy skills required.
This spicy oven baked catfish is marinated in a bold blend of fresh herbs and peppers, then roasted whole in the oven until perfectly tender. It is one of my favorite ways to cook catfish and I know it is going to be a hit at your dinner table too!
🧡 Why You’ll Love This Recipe
My family goes absolutely crazy for this oven baked catfish. We make it at least twice a month and it never lasts more than a day. Honestly, once we start eating, nobody stops until it is all gone.
The secret is in the marinade. You blend red bell pepper, habanero, garlic, ginger, and fresh herbs like thyme, dill, and sage into a smooth, fragrant paste. It gets stuffed right into the fish and soaks into every single bite. So much flavor in every mouthful.
And the best part? The whole thing gets wrapped in foil and baked low and slow so the fish stays incredibly moist. No dry, sad fish here. Just juicy, spicy, fall-off-the-bone catfish that will have everyone asking for seconds.

🧾 Ingredients I Use
- Catfish: This recipe calls for whole catfish instead of catfish fillets. Check your local Asian, Mexican, or African grocery store for frozen or fresh catfish. Be sure to remove the bones before serving.
- Vegetables: I use red bell pepper, garlic, onion, ginger root, and habanero pepper to create a potent, flavorful marinade that soaks into every bite of whole baked catfish.
- Herbs: Fresh thyme, dill, and sage have so much more flavor than dried herbs, but you can use those instead in a pinch.
- Salt to taste.
🔪 How To Make Oven Baked Catfish
- Preheat oven to 400F. Clean and gut the fish. Use the lemon to clean the fish by squeezing the lemon juice on the fish and rubbing it in. Rinse thoroughly when done.
- Place the red bell pepper, habanero, onions, herbs and spices in a blender and blend till smooth.
- Make shallow slices on the fish, about 3 – 4 on both sides. Scoop about half of the pureed mixture into these holes and in the center slit. Keep the other half to use later.
- Completely wrap the fish in foil and place in bottom rack of oven for 45 mins. Open the foil at the top and leave the fish in for another 5 minutes.
- Bring out the fish from the oven and pour the remaining pureed mixture over the fish and serve.
♨️ How To Store and Reheat
This baked whole catfish will keep for a few days in the fridge, but if you have fish lovers in your house, then it will probably last one day or two at the most. To keep it fresh, store it in an airtight container in the fridge for 2-3 days.
To reheat, you can either microwave your leftovers for about a minute or pop them in the air fryer at 350 F for 5-7 minutes or until fully warmed.
💡 My Expert Tips
- You can reduce how much pepper you use in this recipe according to your preference. Or you can omit it altogether.
- I use thyme, dill, and sage, but you can use any herbs of your choice.
- Don’t skip cleaning the fish with lemon. This helps to clean the fish and reduce its sliminess, and also cuts down on the strong fishy smell, which might be a bother to some.
- The fish has to be wrapped in foil before baking as this helps to trap the juices and keep them moist.
- If you like really spicy food, you can also add a dash of cayenne pepper to the vegetable mixture.
- Feel free to garnish with some fresh lemon slices, a little fresh parsley, or a dash of hot sauce (like this Pili Pili sauce) for extra flavor!
🍽️ What to Serve With Baked Whole Catfish
This baked whole catfish tastes great with a veggie dish or salad on the side, like Brussels sprouts, roasted cauliflower, or keto coleslaw. This bacon broccoli salad will also be a great addition!
👩🍳 Questions You Might Have
What temperature should catfish be cooked at?
To bake a whole catfish in the oven, set your oven temperature to 400 degrees. To know when your fish is done, use an instant read meat thermometer. The meat should be at a temperature of 145 degrees F, according to the USDA.
Can you cook whole catfish with the skin on?
Yes! I prefer to keep the skin on catfish for this whole baked catfish recipe. This holds the tender meat together and makes it easy to marinate the whole fish at once in an aromatic blend of vegetables and fresh herbs.
What is the best cooking method for catfish?
There are so many ways to prepare catfish from deep frying fillets to pan-frying catfish on the stove and baking the whole fish in the oven. As a catfish enthusiast myself, my favorite preparations are to make whole baked catfish in the oven, air fry catfish steaks, or to add it to soup recipes, like this Fish Pepper Soup or Western African Okra Soup.
