Ingredients:

  • 750 g / 1.5 lbs Pearl Onions (White or Red, approximately 3 cups, peeled)
  • Water (Enough to cover the onions)
  • 1 teaspoon (5 g) Salt
  • 4 tablespoons (60 g / 1/4 cup) Unsalted Butter
  • 4 tablespoons (30 g / 1/4 cup) All-Purpose Flour (Plain Flour)
  • 360 ml / 1.5 cups Whole Milk (Full-Fat)
  • 120 ml / 1/2 cup Heavy Cream (Double Cream)
  • 1/2 teaspoon (2.5 g) Salt, or to taste
  • 1/4 teaspoon Freshly Ground Black Pepper
  • 1/8 teaspoon Freshly Grated Nutmeg (essential for flavour)
  • 1 tablespoon Fresh Parsley, chopped (flat-leaf preferred)

Instructions:

  1. Prep the Onions: Bring a pot of water to a rolling boil. Drop the pearl onions (unpeeled) into the boiling water for 60 seconds (blanching). Immediately drain and plunge them into a large bowl of iced water to stop cooking.
  2. Peel: Once cool enough to handle, use a small knife to trim the root and stem ends. The skin should now easily slip off.
  3. Simmer: Place the peeled onions and 1 tsp of salt in the medium saucepan. Cover with fresh water. Bring to a simmer, then reduce heat to low, cover, and cook for 20–25 minutes, or until the onions are fork-tender but still hold their shape.
  4. Drain: Drain the cooked onions thoroughly and set them aside.
  5. Start the Roux: Return the empty saucepan to medium heat. Melt the butter until it foams. Whisk in the flour thoroughly until a smooth paste (the roux) forms.
  6. Cook the Roux: Continue stirring for 1–2 minutes to gently cook out the raw flour taste. Do not allow the roux to brown; it should remain pale blonde.
  7. Add Liquid: Gradually whisk in the cold whole milk, pouring slowly to incorporate the roux without forming lumps. Continue whisking constantly until the sauce is smooth and lump-free.
  8. Thicken and Season: Bring the sauce to a gentle simmer, stirring occasionally. It will thicken considerably. Remove from the heat and stir in the heavy cream, salt, pepper, and freshly grated nutmeg. Taste and adjust seasoning as needed.
  9. Combine: Gently fold the reserved, cooked pearl onions into the warm cream sauce. Be careful not to mash the onions.
  10. Reheat: Return the saucepan to very low heat and simmer gently for 5 minutes, allowing the onions to fully warm through and the flavours to meld. If the sauce becomes too thick, add a splash more milk.
  11. Serve: Transfer the creamed onions to a serving dish. Garnish with fresh chopped parsley just before serving.
