How to Make Baked Cod with Mayonnaise Recipe?
Making baked cod with mayonnaise is as straightforward as it gets. If you can mix a few ingredients and handle a baking sheet, you’re set. Here’s how we’ll do it:
Step 1: Preheat Your Oven

Before getting your hands into this recipe, preheat your oven to 450 degrees F. This high temperature helps achieve that lovely browning on top of the mayonnaise mixture. While it warms up, line a rimmed baking sheet with parchment paper to make clean-up a breeze.
Step 2: Prepare the Cod

Pat your cod fillets dry using layers of paper towels. This step is crucial. Cod can hold quite a bit of moisture, and we want to make sure it doesn’t end up stewing in its water as it bakes! Lay down the fillets, cover with more paper towels, and gently press down. You want to absorb the excess moisture without flattening the fish.
Step 3: Arrange the Fillets

Transfer your cod fillets to the prepared baking sheet, making sure to leave a bit of space—about 2 inches should do the trick. This ensures they cook evenly and get a nice crust on top!
Step 4: Blend the Topping

In a mixing bowl, combine the mayonnaise, grated Parmesan cheese, minced garlic, chopped parsley, chives, thyme leaves, oregano, and black pepper. If you’re adding lemon juice and paprika, toss those in too. Grab a whisk or a spoon, and blend everything together until it’s smooth and creamy.
Step 5: Coat the Cod

Now, take the delightful mixture you just made and dollop it evenly over the cod fillets. Use the back of your spoon to spread the mixture so that every inch of the fish is covered—this will help create that coveted crispy topping.
Step 6: Bake Away

Pop the bakin’ beauty into your preheated oven and let it cook for about 12 minutes. You’ll want to keep an eye on it, as oven times can vary. If the top hasn’t browned to your liking, you can switch the oven to broil for about one minute, but be careful—things can go from golden to burnt in a flash!
Step 7: Serve and Garnish
Once your cod is done and looking glorious, pull it out of the oven. If you saved some extra parsley or herbs, sprinkle those on top for a bit of freshness. Serve the cod immediately, and watch it disappear!
Tips
– Choose Fresh Fish: Fresh cod makes a world of difference in taste.
– Alter Toppings: Feel free to experiment with different herbs like dill or basil if parsley and chives aren’t your thing.
– Monitor Cooking Time Closely: Cod can dry out quickly, so keep an eye on the cooking time.
– Don’t Skip the Paprika: A hint of spice adds a nice depth of flavor—even if it’s just a pinch.
– Use Quality Mayonnaise: Opt for a full-fat or homemade mayonnaise for the best creaminess.
How to Store the Leftovers?
If you happen to have any leftovers (though I doubt that!), let the baked cod cool to room temperature, then store it in an airtight container in the fridge. It’ll keep well for about 2-3 days. Reheating can be done gently in the oven or microwave—just be careful not to overdo it. Nobody likes rubbery fish!
What are some recommended side dishes for baked cod with mayonnaise recipe?
1. Quinoa Salad: A refreshing quinoa salad pairs nicely with the richness of the cod. Toss in cucumber, cherry tomatoes, and feta for a burst of flavor.
2. Roasted Vegetables: Roasted asparagus or a medley of seasonal veggies adds crunch and nutrition.
3. Garlic Bread: It’s a classic! Crispy garlic bread never hurts as it’s great for cleaning up the plate.
4. Coleslaw: A tangy coleslaw adds texture and a refreshing crunch that contrasts beautifully with the fish.
5. Couscous: Light and fluffy couscous can soak up those deliciously rich juices.
If the items are not available in your pantry, what are some substitute options for the ingredients?
1. Cod:Tilapia or haddock work well if you can’t find cod.
2. Mayonnaise: If you’re looking for alternatives, Greek yogurt can create a similar consistency, or sour cream for a tangy twist.
3. Parmesan Cheese:Pecorino Romano or grated mozzarella will work instead of Parmesan if you’re looking for a slightly different taste.
4. Fresh Herbs: If you don’t have the fresh ones, using dried herbs is okay—just remember to use about a third of the amount since dried herbs are more concentrated.
5. Garlic: In a pinch, garlic powder or minced garlic in a jar can substitute for fresh.
