A humble wintery cream of leek and potato soup can be brightened up with springy lemony & herby flavors and dressed up with windowpane (or sandwiched semi-transparent layers of) oven-baked crispy leek & potato chips, filled with more fresh herbs too. All of this is because here in France, we thought that spring had already placed a solid foot in the door, but winter stepped right back in and is still blocking the doorway to spring ! We’ll wait patiently because patience, they say, is a virtue, but I don’t know if that would be very European of us, after all … !

This humble soup is vegetarian. The only deeper meat-like flavor is due to the addition of just a little bit of “marmite” in the home-made broth, which is a very British, dark brown and salty vegetarian yeast spread, and I guess we could say that it’s like a thick fermented European version of a soy miso paste or soy sauce. I often use it to flavor most vegetarian broths and sauces.

The broth is home-made and extremely flavorful and is probably the most important preparation. A good broth will always make a good soup and the objective is to prepare a tasty simmering liquid that will be strained and then incorporated to deliver all the extra flavors needed without adding them again to the cooked leeks and potatoes.

Try to use as much as possible of the light green parts of the leek and yellow and not white potatoes to get that light greenish-yellow color of the soup but adding more fresh green herbs before puréeing the mixture will also contribute to the pale green color.

The dill and lemon are my additions, like a magical spell that I cast to bring spring back to France. My fingers remain crossed.

And the baked chips are a decorative addition to make this humble and simple potato and leek soup more festive … :)

instructions

  • slice the white parts and all the light green parts of the leek (even those inside the darker leaves towards the ends but save 12 slices of light green leek leaves measuring 7 x 3 cm each for the chips) and rinse under cold water if slightly sandy and set aside
  • scrub and wash and peel the potatoes and slice into smaller cubes and set aside (you’ll be using the washed peels in the broth and another unpeeled and smaller or baby potato for the chips) and set aside
  • prepare the broth with all the ingredients mentioned above, bring to a boil, reduce to medium-low heat, cover with a lid and let simmer for 90-120 minutes, then let cool down, strain well and recuperate 1 liter minimum of broth (approximately 150-250ml will be lost to evaporation or trapped in the solids) and set aside
  • melt the butter with the olive oil in large casserole at medium-high heat, add the chopped leek and potato, add the salt and pepper and cook for 5 minutes until tender, stirring occasionally, then add the lemon juice and scrape the browned bits on the bottom of the casserole with a wooden spoon, add the strained broth, bring to a boil, reduce the heat to medium-low heat, cover with a lid and simmer for 30 minutes, until everything is fork-tender, let the soup cool down, use an immersion blender to reduce it to a purée, add the cream and more fresh herbs, mix again, adjust to your taste and set aside, covered with a lid
  • to prepare the herb chips (while the soup is simmering), very thinly slice a small unpeeled potato into 12 thin slices (approximately 7 x 3 cm each) and the saved light green leek slices from earlier (also 7 x 3 cm each) and place on 2 small baking trays covered with sheets of baking paper that you pre-brushed with some olive oil and sprinkled with salt and pepper before laying down the first slices
  • place the first half of the chips on the baking paper, place the fresh herbs leaves or fronds on top of the first half of the potato or leek slices, cover with another potato or leek leaf slice, brush the tops with olive oil and sprinkle with salt and pepper again, cover with a another sheet of baking paper, weigh down with another baking sheet or tray and bake in a 200°C pre-heated oven for 15 minutes maximum, then remove the top baking tray and baking paper and bake uncovered for an additional 5 minutes maximum until crispier, remove from the oven, let cool down and set aside
  • garnish each warm bowl of cream soup with a drizzle of light cream, one baked leek chip, one baked potato chip, one small quarter of a lemon slice, some fresh herbs and a sprinkling of black pepper, and serve with crusty bread.
