In this recipe, I use simple, fresh ingredients to bring out the best in cod fillets. Cod is a mild fish that takes on flavors well. The unsalted butter adds richness, while fresh lemons give it brightness. You will also need garlic to add depth and thyme for an earthier note. The salt and pepper enhance the flavors in each bite.
For the liquid components, you can use chicken broth for more flavor or vegetable broth if you prefer. The broth helps cook the fish and keeps it moist. Finally, fresh parsley brightens the dish when you serve it, making it look and taste even better.
Gather these ingredients before you start. This will make your cooking smooth and fun!

Step-by-Step Instructions
Preparation Steps
- First, pat the cod fillets dry with paper towels. This helps the seasoning stick well.
- Next, sprinkle salt, black pepper, and dried thyme on both sides of the fillets. This adds great flavor.
- Now, set your Instant Pot to the 'Sauté' setting. When it is hot, add the unsalted butter and minced garlic. Sauté for about one minute. You want the garlic fragrant but not brown.
Cooking Process
- After the garlic is ready, add the juice of one lemon to the pot. Pour in the chicken or vegetable broth, then stir to combine.
- Carefully place the seasoned cod fillets on top of the liquid. Arrange the lemon slices over each fillet. This gives extra flavor and looks nice.
- Close the Instant Pot lid and set the valve to 'Sealing'. Use the 'Pressure Cook' setting and adjust the time to three minutes.
Finishing Touches
- Once the cooking time is up, do a quick release. Turn the valve to 'Venting' to let the steam out.
- Use a slotted spatula to remove the cod fillets from the pot. If you like, switch back to 'Sauté' mode. Let the sauce simmer for a few minutes to thicken it.
- Serve the cod fillets drizzled with the lemon garlic butter sauce. Add fresh parsley on top for a nice touch.
Tips & Tricks
Perfecting the Recipe
To make the best cod fillets, choose fresh, firm fillets. Look for cod with a bright color and no strong fishy smell. If you prefer a milder taste, you can adjust the seasonings. Add more or less salt and pepper based on your taste buds. You can also add more thyme for a stronger flavor.
Cooking Techniques
Using the sauté function is key in this recipe. It builds flavor right from the start. Start by melting the butter and cooking the garlic. This step makes your dish fragrant and tasty. To keep your cod tender, don’t overcook it. Three minutes under pressure is perfect. Remember to do a quick release to avoid overcooking.
Serving Suggestions
For sides, steamed vegetables or fluffy rice work well. They balance the rich lemon butter sauce. For a nice look, arrange the cod on a plate with lemon slices. A sprinkle of fresh parsley adds a pop of color. This makes your meal not just tasty but lovely to view, too.
Pro Tips
- Fresh Ingredients: Always use fresh cod fillets for the best flavor and texture. Frozen fillets can work in a pinch, but fresh will give you that melt-in-your-mouth quality.
- Butter Substitute: If you want a lighter option, you can substitute olive oil for butter. It will still provide a delicious flavor, with a Mediterranean twist.
- Herb Variations: Feel free to experiment with different herbs! Dill or parsley can be great alternatives to thyme, adding unique flavors to the dish.
Variations
Flavor Enhancements
You can easily change the flavor of your cod. Adding herbs or spices makes a big difference. Try adding dill for a fresh touch or paprika for a gentle heat. Both options can brighten the dish. You can also use other citrus fruits. For a twist, use lime or orange juice instead of lemon. This will add unique flavors to your meal.
Dietary Adjustments
If you need gluten-free options, this recipe is already great. All the ingredients are naturally gluten-free. You can also make low-sodium adjustments. Use low-sodium broth instead of regular. This keeps the dish tasty while being gentler on your salt intake.
Cooking Methods
You don’t have to just use the Instant Pot for this recipe. Baking the cod in the oven is simple. Preheat the oven to 400°F (200°C). Place the seasoned cod in a baking dish with the lemon and broth. Bake for 12-15 minutes. Another option is grilling the cod. This gives a nice char and smoky flavor. Grill for about 5 minutes per side. Each method will offer a new taste experience.
Storage Information
Storing Leftovers
To keep your cod fillets fresh, follow these steps. First, let the cod cool down to room temperature. Then, place the fillets in an airtight container. This keeps out air and moisture. You can also wrap them tightly in plastic wrap. Store the cod in the fridge for up to three days. This helps maintain its taste and texture.
Reheating Tips
Reheating needs a gentle touch to keep the cod juicy. Use a microwave on low power. Heat in short bursts of 30 seconds. This way, the fish warms evenly without drying out. You can also reheat in a skillet. Add a splash of broth to the pan. Cover it to trap steam and heat until warm. Aim for a temperature of 145°F for safe eating.
Freezing Considerations
If you want to save cod for later, freezing works well. Wrap each fillet in plastic wrap, then place them in a freezer bag. Remove as much air as possible. Cod can stay frozen for up to three months. When ready to eat, thaw it overnight in the fridge. This keeps the fish flavorful and tender. Avoid thawing in warm water, as this can ruin its texture.
