Ingredients

  • 1 teaspoon olive oil
  • 1 ½ tablespoons butter
  • 1 garlic cloves minced
  • 2 tablespoons shallots minced
  • 21 ounces (600g) Brussels sprouts cored and halved
  • ¼ teaspoon sea salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon nutmeg
  • ½ cup (125ml) double cream or heavy whipping cream
  • 1 cup (235g) white cheddar cheese

  • 1 ¾ ounces (50g) walnuts chopped

Instructions

  • Preheat the oven to 375 degrees F / 190 degrees C.
  • Heat an oven proof skillet over medium heat, then add the oil and butter. When the butter has melted add garlic, onion, and Brussel sprouts.
  • Season with salt and pepper and sauté for 10-12 minutes or until the sprouts are tender on the inside and crispy on the outside.
  • In a small bowl, whisk the nutmeg into the cream.
  • Remove the skillet from the heat and pour cream on the Brussel sprouts.
  • Sprinkle cheddar and parmesan on top with half of the walnuts. Bake for 10 minutes until the cheese melts.
  • Remove and garnish with more walnuts, grated parmesan, and parsley.

Notes

    • Trim the stem end of the Brussels sprouts and cut larger sprouts in half. Check for any discolored or damaged outer leaves and remove them. 
    • Use an oven-proof pan or transfer to a baking dish.
    • Whenever possible, grate your cheese fresh. Pre-packaged grated cheese often contains anti-caking agents, which can affect the texture of your gratin sauce.
    • Pour the cream mixture evenly over the sprouts. There is no need to stir it before adding the cheese.
    • Don't be shy about the seasonings. The sea salt, black pepper, and nutmeg should be enough to elevate the flavors. Taste as you go and adjust to your liking.
    • Add the chopped walnuts on top just before serving. 
    • Bake until the top is golden brown and the Brussels sprouts are tender when pierced with a fork. Since we have precooked the sprouts, this step should only take about 5 minutes. 
    • Allow the gratin to rest for a few minutes after removing it from the oven. This helps the flavors meld together and makes it easier to serve.
    • You can prepare the gratin in advance and refrigerate it. When you're ready to serve, simply bake it until heated through. This makes it a convenient dish for busy gatherings.
    • Garnish with fresh thyme.
    • Storage - keep leftovers in an airtight container inside the fridge for 4 days.
