4 cod fillets: About 6 ounces each, fresh or properly thawed.
1 large celeriac: Roughly 2 pounds, look for one that feels firm and heavy.
2 tablespoons olive oil: A good quality extra virgin for flavor.
2 tablespoons butter: Unsalted is preferred, for richness in the mash.
1/4 cup milk: Or cream for an even more luxurious, richer mash.
Salt and black pepper: To taste, for seasoning both the fish and the celeriac.
Fresh parsley: Chopped, for a bright, fresh garnish.

Fresh Cod Fillets: The Star of Your Cod & Smashed Celeriac

For your Cod & Smashed Celeriac, aim for fresh, thick cod fillets, ideally about 1-inch thick. This ensures they cook evenly and remain incredibly moist. I usually go for skin-off for pan-frying, but skin-on works beautifully too if you like that crispy skin texture!

Crafting Creamy Smashed Celeriac

When selecting your celeriac for the Smashed Celeriac, look for one that’s firm, heavy for its size, and avoid any with soft spots. A large one, around 2 pounds, yields a good amount of mash for four servings. The butter and milk (or cream) are crucial for achieving that silky, creamy texture we’re after!

Step-by-Step: How to Prepare Cod & Smashed Celeriac

Making this Cod & Smashed Celeriac dish is surprisingly straightforward, and I’m going to walk you through each step so you can achieve perfect results every time. We’ll tackle the celeriac first, then move on to the cod, and finally bring it all together for a meal that looks and tastes like it took hours. Pay attention to the timing, especially for the fish, and you’ll be enjoying a fantastic dinner in no time!

Preparing the Celeriac for the Smashed Celeriac

First things first, let’s get that celeriac ready for your incredible Smashed Celeriac. Start by peeling the celeriac thoroughly; the skin can be a bit gnarly, so use a sharp vegetable peeler or a small knife. Once peeled, chop it into roughly 1-inch cubes. Place these cubes in a saucepan, cover them with cold water, and add a generous pinch of salt. Bring it to a boil, then reduce the heat and let it simmer for about 15-20 minutes, or until the celeriac is incredibly tender and easily pierced with a fork. This ensures a super smooth mash!

Pan-Frying Your Delicious Cod

While the celeriac is cooking, turn your attention to the cod. Pat your cod fillets thoroughly dry with paper towels – this is crucial for getting a nice sear! Season both sides generously with salt and freshly ground black pepper. Heat 1 tablespoon of olive oil in a large non-stick skillet over medium-high heat until it shimmers. Carefully place the cod fillets in the hot skillet. Cook for 3-4 minutes per side, depending on thickness, until the fish is opaque throughout and flakes easily with a fork. Don’t overcrowd the pan; cook in batches if necessary.

Bringing Together the Cod & Smashed Celeriac

Once your celeriac is perfectly tender, drain it well and return it to the saucepan. Add the butter and milk (or cream) to the warm celeriac. Grab your potato masher and mash until it’s smooth and creamy. Taste and season with more salt and pepper as needed; this is your chance to get it just right! To serve, spoon a generous portion of the Smashed Celeriac onto each plate, top with a perfectly pan-fried cod fillet, and finish with a sprinkle of fresh chopped parsley for a pop of color and freshness. Enjoy your beautiful Cod & Smashed Celeriac!

Expert Tips for Perfect Cod & Smashed Celeriac

Achieving truly perfect Cod & Smashed Celeriac isn’t hard, but a few expert tips can elevate your dish from good to absolutely amazing. Don’t skip drying your fish! Excess moisture means steaming instead of searing, and you won’t get that lovely golden crust. Also, taste as you go, especially when seasoning the celeriac mash. Salt and pepper are your friends here, and adjusting them to your preference makes a huge difference. Finally, resist the urge to overcook the cod; it dries out quickly.

Enhancing the Flavor of Your Cod & Smashed Celeriac

To really make your Cod & Smashed Celeriac sing, consider a squeeze of fresh lemon juice over the cooked cod right before serving – it brightens everything up! For an even deeper, nuttier flavor in your celeriac mash, try roasting the celeriac cubes instead of boiling them. Just toss with a little olive oil, salt, and pepper, and roast until tender before mashing.

Storage and Reheating Your Cod & Smashed Celeriac

If you happen to have any delicious Cod & Smashed Celeriac leftovers (which rarely happens in my house!), store them properly to enjoy later. Place both the cooked cod and the smashed celeriac in separate airtight containers in the refrigerator for up to 2-3 days. To reheat, gently warm the celeriac mash on the stovetop over low heat, adding a splash of milk if needed to restore its creaminess. The cod is best reheated briefly in a preheated oven at 275°F (135°C) for about 10-15 minutes, or until just warmed through, to prevent it from drying out.
