Prep time: 5 minutes

Cook time: 20 minutes

Total time: 25 minutes

Servings: 2


2 Leeks

1 tbsp Butter / Vegan butter

1 white wine (small glass - optional)

1 Lemon (juice and zest)

100 g Creme fraiche / vegan creme fraiche

1 tsp whole grain mustard

Parmesan / vegan parmesan

200 g Spaghetti 

Salt & pepper


  1. Make the leek fondue: Slice the leeks very thinly. Rinse under cold water to get rid of any dirt. Add the butter/vegan butter to a large pan. When melted and hot, add the leeks. Season and cook over medium heat for 5 minutes, until tender. Deglaze with the white wine, add the creme fraiche/vegan creme fraiche and the mustard. Cook for 10 minutes, or until the liquid has reduced and you have a creamy leek fondue.
  2. Cook the spaghetti: While the leeks are cooking, cook the pasta in boiling salted water until al dente. Reserve a little pasta water, and drain.
  3. Finish the leek pasta: Add the drained pasta to the pan with the leek fondue. Add a few tablespoons of pasta water, the grated parmesan/vegan parmesan and toss well to coat. Turn off the heat, add the lemon juice and zest, and season to taste. Serve nice and hot.
