Velvety Parsley and Onion Sauce

A velvety parsley and onion sauce that rescues any plate in 15 minutes: creamy, with the freshness of the parsley and a squeeze of lemon that lifts it. It goes with pasta, fish or steamed vegetables.

And it solves an everyday problem along the way: the bunch of parsley that always ends up going soft at the back of the refrigerator.

The flour needs its minute. A roux cooked for one or two minutes loses the raw flour taste; skipped, it stays in the sauce and no amount of cream covers it.

Ingredients

Measurements
🍽 4 servings
  • 40 g butter
  • 1 onion, finely chopped
  • 2 heaping tbsp fresh parsley, chopped
  • 1/2 tbsp all-purpose flour (plain flour)
  • 125 ml stock (1/2 cup)
  • 1 bay leaf
  • 200 g heavy cream (double cream)
  • 4 tbsp grated cheese
  • 1 tsp lemon juice
  • Salt and pepper, to taste

Method

  1. 1

    Soften the onion in the butter over medium heat until translucent, without letting it color. Add the chopped parsley and give it a moment.

  2. 2

    Sprinkle in the flour and stir well to make a quick roux. Cook it for a minute or two so the raw flour taste goes away.

  3. 3

    Pour in the stock along with the bay leaf and cook for a few seconds, stirring, until there are no lumps left.

  4. 4

    Add the cream, the grated cheese and the lemon juice. Season and emulsify over low heat, stirring, until the sauce thickens.

  5. 5

    Remove the bay leaf and taste. If it thickens too much on standing, loosen it with a spoonful of stock.
