Asparagus and Gruyère Tart

Edgar Farms Asparagus with my own Homemade Gruyère


 Asparagus and Gruyère are a classic pairing and a scintillating savory Spring indulgence.


 Rainy days are perfect for pastry.


I usually never cook with the cheese I make. It is just too precious, but this asparagus called for only the best!


 Cutting the boarder, not all the way through, but carefully with a very sharp knife is the best “trick” I have learned making puff pastry tarts; corners must meet.


 Making two, the spring form tart pan was the perfect second option for comparison.


 The classic recipe calls for Dijon mustard to be spread on the bottom… but, I live in Alberta and the Brassica Mustard company makes the best mustards in the province. They would rival any world class mustard, and the fact that I chose to use this one over Dijon speaks volumes about its savory flavor. The texture adds a brilliant titillating tidbit to each bite. It is flavourful: a little goes a long way.


 Ensure there is none on the crust.


 Again, very important to have nothing on the crust but the egg wash. Below, tart numero duo.


 The old adage that “simple is best” is exemplified in this unforgettable culinary masterpiece: pastry, asparagus, mustard, cheese and thyme. Each ingredient must be the best possible and you can see how extraordinarily easy this is to make. The presentation almost emoted a fluidity in the French language I have yearned for… but not yet mastered.


 It is gorgeous. It is effortless. It is a feast of flavour. It is a Spring tradition.


Asparagus and Gruyère Tart


  • 375g pack puff pastry (President’s Choice brand is made with read butter)
  • 1 bunch thin/medium asparagus (approximately 18 spears)
  • 2 level teaspoons Dijon or 1 tablespoon of Grainy Brassica Mustard
  • 150g Gruyère, grated (the medium Sylvan Star Gruyère is award winning and perfect if you don’t make your own, or the Swiss award winning Emmi Kaltbach Le Gruyère, AOC if you live elsewhere)
  • A few sprigs fresh thyme
  • 1 egg, beaten
  • Freshly ground black pepper


  1. Preheat the oven to 400˚F
  2. On a lightly floured surface, roll out the pastry to a rectangle measuring about 23cm x 35cm and place on a large, greased baking sheet
  3. With a knife, lightly score a 2cm border around the edge of the pastry
  4. Wash the asparagus, trimming off ends, leaving each spear about 18cm or 7 inches long
  5. Carefully spread the mustard over the inner rectangle of the pastry, sprinkle the grated Gruyère, over it and arrange the trimmed asparagus spears evenly on top
  6. Pull the leaves off the thyme and scatter over the tart
  7. Brush the border of the tart with a little beaten egg, place in the oven and cook for 20-25 minutes until the asparagus spears are cooked through, the tart is golden and the cheese is bubbly
  8. Remove the cooked tart from the oven and season with a little freshly ground black pepper; serve immediately

    Your tart is a work of art, Valerie. :-) Seriously, I feel like I’ve been to a food gallery today. It makes me dream of Spring and France and lush gardens and sunshine and all those good things. :-)

      Wonderful! That is exactly how I felt pulling it out of the oven. So happy that translated to you!

    What a beautiful tart, Valerie! I really need to try this and wish I had some homemade gruyere for it :). Your photos are wonderfull! New camera?

    • Valerie Lugonja says

      It is a lovely and very simple recipe, Susan: a French Classic. Thanks – no new camera, but I am learning to use it better.

    • Valerie Lugonja says

      So funny that you posted about the mustard, I was making the tart, and of course, substituted this incredible concoction for the Dijon in the classic recipe! Great minds think alike.

    • Valerie Lugonja says

      Let me know how it goes! So simple; so delicious!
      Hope you have the same experience!

    This looks amazing! So simple and delicious and totally worthy of your homemade cheese! We just tasted our Gruyere today and I’ll be posting about it later :)

    This was absolutely delicious! I was able to watch it be made and got the luxury of tasting it! The mustard was subtle as was the thyme, but both needed. This was by far, the best savoury tart I have ever eaten!

  6. Teresa says

    Wow Val…this post totally made my mouth water…have to make myself one of these as soon as I get my hands on some of this asparagus!

    Happy Wednesday!

      This was an “Ode to Spring” on a plate. Simple and so yummy. Thanks for stopping by.

    I made a thin pizza that combines asparagus, ham and gruyère. It is so yum! Nice that you are using your own cheese for your tart.
