How to make Vegetarian Strudel with Mushrooms and Leeks

Ingredients:

  • 12 sheets phyllo pastry, thawed
  • 12 tbsp butter, melted
  • 1 large egg, beaten
  • 4 tbsp butter (for sautéing)
  • 16 oz cremini or baby Bella mushrooms, cleaned and thinly sliced
  • 6 oz shiitake mushrooms, cleaned, roughly chopped, tough stems removed
  • 1 leek, thinly sliced and well cleaned (light green and white parts only)
  • 4 cloves garlic, minced
  • 1/2 cup grated parmesan cheese
  • 2 tbsp chopped parsley
  • Salt and freshly ground black pepper, to taste

Directions:

Make the filling:

  1. Preheat oven to 400°F (200°C).
  2. Melt 4 tablespoons of butter in a large nonstick frying pan over medium heat.
  3. Once the butter is melted, add the sliced leeks. Cook for about 8-10 minutes until they become soft and slightly caramelized. After that, transfer them to a large mixing bowl.
  4. Next, add all the mushrooms to the same pan and season with salt and pepper.
  5. Cook the mushrooms for about 12-15 minutes, stirring occasionally until most of their liquid is evaporated.
  6. After cooking, add the mushrooms to the bowl with the leeks. Then stir in the parmesan cheese, minced garlic, and chopped parsley. Mix well to combine.

Assembly/Baking:

  1. Line a cookie sheet with parchment paper and brush it lightly with melted butter to prevent the phyllo pastry from sticking.
  2. Lay out one sheet of phyllo pastry and brush it with melted butter. Place another sheet of phyllo on top and brush that with butter as well. Repeat this step until you have used a total of four sheets of dough.
  3. Brush the edges of the dough with the beaten egg to help seal the strudel.
  4. Take 1/4 of the mushroom mixture and spread it over one end of the phyllo dough, leaving about a 1/4 inch margin around the edges.
  5. Use the parchment paper to help fold the edge up to create a seal around the mushrooms.
  6. Carefully roll the dough toward the empty end to form a strudel, tucking in the end to seal it properly. Repeat steps 2-5 until you have made a total of four strudels. To keep the phyllo dough moist and easy to work with, cover the remaining sheets with a damp towel.
  7. Brush the top of each sealed strudel with melted butter.
  8. Bake the strudels seam side down for about 15 minutes or until golden brown and crisp.
  9. Allow them to cool for about 15 minutes. Slice each strudel into 3 or 4 pieces and serve warm.

Nutritional Benefits

This dish is not only tasty but also packed with nutrients. Mushrooms are low in calories and high in fiber, offering great health benefits such as boosting the immune system and supporting heart health. Leeks are a good source of vitamins A and C, as well as antioxidants. The use of phyllo pastry allows for a lighter option compared to traditional pastry, while still providing that crispy texture. Plus, the addition of cheese and parsley adds calcium and vitamins, making this dish a wholesome meal.

What to Serve With Vegetarian Strudel

Consider serving the strudel alongside a fresh green salad. A simple mix of arugula, spinach, or mixed greens dressed in lemon vinaigrette would be perfect. You could also offer some dipping sauces like garlic aioli or a tangy yogurt sauce for an added flavor dimension. If you want a more filling meal, pair it with roasted vegetables or a side of potato salad.

How to store Vegetarian Strudel

To store leftover strudel, allow it to cool completely before wrapping it in plastic wrap or placing it in an airtight container. It can be kept in the refrigerator for up to 3 days. For longer storage, you can freeze it. Wrap the strudels tightly in plastic wrap and then place them in a freezer-safe bag. Frozen strudels can last for up to 2 months. When ready to eat, thaw overnight in the refrigerator and then reheat in the oven until warmed through.

Tips and Mistakes to Avoid

  • Keep phyllo dough covered: Phyllo pastry dries out quickly, so keep it covered with a damp towel while working to prevent it from becoming brittle.
  • Use enough butter: Don’t skimp on the melted butter when brushing the layers of phyllo. This helps achieve a crispy and golden look.
  • Don’t overfill: It’s easy to be tempted to add too much filling. Stick to the recommended amount to ensure you can roll and seal the strudel correctly.

Variations

You can easily customize this strudel. For a spicier twist, add some red pepper flakes to the mushroom filling. You can also try different vegetables like spinach or kale. For a different flavor, incorporate feta cheese instead of parmesan or add some nuts like walnuts for added texture.

FAQs

Can I make this strudel ahead of time?
Yes, you can prepare the filling and assemble the strudels in advance. Just cover them and store in the refrigerator for up to 24 hours before baking.

Can I use other types of mushrooms?
Absolutely! Feel free to use any mushrooms you like, such as button mushrooms or portobello. Each variety brings a slightly different flavor.

What can I use if I don’t have phyllo pastry?
If you can’t find phyllo pastry, you could use puff pastry instead. Simply roll it out, fill, and bake according to package instructions. Keep in mind that the texture will be slightly different.
