Ingredients for Cod and Leek Gratin with Mustard

  • 400g cod fillets – boneless and skinless
  • 2 leeks, chopped – white part only
  • 200ml cream – heavy cream for richness
  • 2 tablespoons mustard – Dijon works beautifully
  • 100g cheese (such as Gruyère) – grated, for that perfect topping
  • Salt and pepper to taste
  • Butter for greasing the dish

Step-by-Step Instructions

  1. Preheat the Oven: Begin by preheating your oven to 180°C (350°F). This will ensure that your gratin bakes evenly.
  2. Prepare the Leeks: In a pan, melt a bit of butter over medium heat. Add the chopped leeks and sauté them for about 5-7 minutes or until they become soft and slightly translucent.
  3. Mix the Cream and Mustard: In a separate bowl, combine the cream and mustard, whisking until well blended. Season with salt and pepper.
  4. Layer the Dish: In a greased baking dish, place half of the sautéed leeks at the bottom. Add the cod fillets, ensuring they’re evenly spaced. Pour half of the cream mixture over the cod, then layer the remaining leeks and finish with the rest of the cream.
  5. Add Cheese: Sprinkle the grated cheese all over the top. This will melt into a delightful crust.
  6. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is golden and bubbling.
  7. Serve: Once out of the oven, let it cool for a few minutes before serving. This allows the flavors to meld beautifully.

Top Tips for Perfecting Cod and Leek Gratin with Mustard

  • Substitutions: If cod isn’t your favorite, you can use any firm white fish like haddock or pollock that suits your dietary preferences.
  • Timing: Make sure to sauté the leeks properly; they should be soft but not browned. This will add a lovely flavor without bitterness.
  • Avoid Mistakes: Don’t rush the baking. Letting the cheese develop a lovely crust takes patience, but it’s worth it!

Storing and Reheating Tips

To keep your Cod and Leek Gratin with Mustard fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. If you’d like to keep it longer, it can be frozen for up to a month.

When it’s time for a reheat, place it back in a preheated oven at 180°C (350°F) until warmed through—this helps maintain the lovely textures of the dish. The cheese may not get quite as crispy again, but a quick broil at the end will help revive that golden layer.

This dish is a celebration of simple, hearty flavors designed to nourish and comfort. Give Cod and Leek Gratin with Mustard a try for your next family meal, and watch as it becomes a beloved staple in your home!
