How to Make the Mushrooms

The first step in making Cheesy Mushroom Pastries is preparing the mushrooms. While you are preparing the mushrooms, preheat the oven to 400°F. To make the mushrooms, melt the butter in a saucepan over medium-high heat. Add the mushrooms and shallots, cooking for about 5 minutes. Next, add the Worcestershire sauce and garlic, sauteeing for about 15 minutes, or until all the liquid has evaporated. Season with salt and pepper.

Assembling the Pastries

Now that you have the mushrooms ready, it’s easy to prepare the pastries.

  1. Cut 16 squares (about 2 inches by 2 inches) out of your thawed puff pastry dough. (You might have some extra dough.)
  2. Place the squares on two lined baking sheets. Brush the egg wash over each square of puff pastry.
  3. Sprinkle each with your shredded cheese, topped with a spoonful of the mushroom mixture.
  4. Bake for about 10 minutes.
  5. Add more cheese and cook for an additional 5 minutes. Sprinkle the tops of the bites with thyme and watch these Cheesy Mushroom Pastries disappear!

Do I Have to Use Gruyere Cheese?

If you want a nice and creamy cheese to top your puff pastry, then yes, you have to use Gruyere cheese for your Cheesy Mushroom Pastries. Plus, Gruyere cheese has an earthy, nutty flavor that should not be confused with regular Swiss cheese you can find at the store. Fortunately, Gruyere cheese is easier to find than it used to be. However, if you MUST use an alternative cheese, look for Comte cheese, Emmental, or Jarlsberg cheese. Any cheese you choose should be a high moisture cheese for better melting.

How to Mince Garlic

Fresh is always better when it comes to ingredients, and garlic is no exception. Please do not go out and buy minced garlic in a jar, thinking you will save time. You will not save enough time for this to be worth it. If you have a fork and a garlic clove, you can have minced garlic. I’m serious! Simply peel the garlic clove and press down with the tines of your fork. Then, press down again in another direction. Keep doing this until you have the clove as minced as you want. (Don’t forget to take out the garlic stem.) You can also smash the clove with the side of a knife and chop from there. You got this!
