Why is fish so intimidating? Once you break the ice with a couple of easy fish recipes you’ll realize it’s actually a super quick and easy way to get dinner on the table fast! I LOVE fish and have created dozens of recipes over the years. I’ll give you some tips to ensure your fish doesn’t get funky or overcooked or flavorless.
This particular recipe is great to start with if you’re new to cooking with fish. Pesto adds such a burst of flavor to any fish you smear it on. I included a homemade pesto recipe (with or without cheese), but you can use store-bought to make it even easier!

Substitutions for Pesto Oven Baked Fish
- Just about any fish would do. White fish like halibut or rockfish would do really well. So would salmon. If you use thinner white fish like tilapia or dover sole, you’ll want to reduce the baking time quite a bit.
- The homemade lemon-basil pesto recipe that I included below is delicious and dairy-free. The lemon keeps the basil from turning brown and brightens the flavor. You could also change it up by using Dill Pesto or Cilantro Pesto
How to make Oven Baked Fish with Pesto
- Preheat the oven to 350°F (180°C).
- First zest the lemon and place the zest in the work bowl of a food processor. Cut the lemon in half.
- Grab a glass baking dish (8 or 9-inch square) and squeeze in the juice from one lemon half. Add the oil, garlic cloves, salt, and pepper. Whisk with a fork to blend. Add the cod to the baking dish and turn several times to coat. Let it stand for 15 minutes.
- In the work bowl of a food processor, add the lemon zest and the juice from the other lemon half. Add the basil, pine nuts, garlic, salt, and pepper. Process until finely chopped. While the machine is running, slowly drizzle in the olive oil. Process until thoroughly combined.
- Place about 2 tablespoons of pesto on each fillet. Cover and bake for 15-20 minutes, or until the fish flakes easily with a fork.
- Serve with additional pesto and lemon wedges.
Tips for making Pesto Fish
- Don’t overcook it. The fish should easily flake with a fork.
- Covering during baking. This will prevent your fish from drying out as well as sealing in the flavors.
What to serve with this Pesto Baked Cod Fish
I love serving this delicious fish with a Lemon Herb Rice, Coconut Rice or Mashed Potatoes.
Make sure to serve with additional pesto and lemon wedges!
How to store Baked Fish
Store any leftover fish in an airtight container, in the fridge for 3-4 days.
Reheating Pesto Fish
- I recommend reheating your fish in the oven for about 5-8 minutes.
- You could also enjoy any leftovers cold!

Pyrex or Corningware? I have a glass baking dish as recommended. The captain loin cut cod I have is one piece (1.23lb.), and for presentation, I prefer not to portion it, so I am using my oval Corningware dish. What is the internal temperature of the Cod in your recipe?

The recommended temperature for cooking fish safely is 145. I like to pull it at 140 and let the residual heat bring it all the way to 145 so it doesn't overcook.

Hi! I apologize for the oversight. The fish cooks at 350 degrees F. I added that to the recipe. Thank you for catching my mistake!

What temperature do you bake it at? 400F? It's not listed in the recipe or notes/comments.
Thanks
