Ingredients
For the Puff Pastry Cups
- 1 sheet frozen puff pastry, thawed
- 1 egg
- 1 tablespoon water
- 1 tablespoon grated Parmesan cheese, optional
- A pinch of black pepper
For the Creamy Mushroom Filling
- 2 tablespoons butter
- 8 oz (225 g) mushrooms, finely chopped
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 2 tablespoons all-purpose flour
- ¾ cup heavy cream
- ½ cup chicken or vegetable broth
- ½ teaspoon dried thyme
- ½ teaspoon Italian seasoning
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ cup grated Parmesan cheese
- 1 tablespoon fresh parsley, chopped
Instructions
1. Prepare the Puff Pastry
Preheat your oven to 400°F (200°C).
Lightly grease a standard 12-cup muffin pan.
Place the thawed puff pastry on a lightly floured surface and gently roll it out just enough to smooth the creases.
Cut the pastry into 12 squares.
Carefully press each square into a muffin cup, gently pushing the dough down and up the sides to form a small cup.
Don’t stretch the dough too aggressively, as this can cause it to become thin and tear.
2. Prepare the Mushroom Filling
Melt the butter in a large skillet over medium heat.
Add the chopped mushrooms and cook for 5–7 minutes, stirring occasionally. Continue cooking until the mushrooms release their moisture and begin to turn golden brown.
Add the diced onion and cook for another 3–4 minutes, until softened.
Stir in the minced garlic and cook for about 30 seconds.
3. Make the Cream Sauce
Sprinkle the flour over the mushroom mixture.
Stir continuously for about 1 minute to cook out the raw flour taste.
Gradually pour in the broth while stirring.
Slowly add the heavy cream and continue stirring until the mixture becomes smooth and creamy.
Add the thyme, Italian seasoning, salt, and black pepper.
Cook for approximately 2–4 minutes, until the filling has thickened.
Remove from the heat and stir in the Parmesan cheese and fresh parsley.
Allow the filling to cool for a few minutes.
4. Fill the Pastry Cups
Spoon the creamy mushroom mixture into each puff pastry cup.
Fill them generously, but don’t overfill them because the filling can bubble over during baking.
If desired, sprinkle a little extra Parmesan cheese over the tops.
5. Add the Egg Wash
Whisk together the egg and 1 tablespoon of water.
Lightly brush the exposed puff pastry edges with the egg wash.
This gives the pastry a beautiful golden-brown finish.
6. Bake
Place the muffin pan in the preheated oven.
Bake for approximately 18–22 minutes, or until the puff pastry is puffed and golden brown and the filling is bubbling.
Keep an eye on them during the final few minutes because puff pastry can brown quickly.
7. Cool and Serve
Remove the pan from the oven and allow the pastry cups to cool for about 5 minutes.
Carefully remove them from the muffin pan.
Garnish with fresh parsley and a little Parmesan before serving.
Tips for Perfect Puff Pastry Cups
Keep the pastry cold: Puff pastry works best when it’s chilled. If it becomes very soft while you’re preparing the cups, place it in the refrigerator for 10–15 minutes.
Cook the mushrooms thoroughly: Mushrooms contain a lot of water. Cooking them until their moisture has evaporated prevents the filling from becoming watery.
Cool the filling slightly: Very hot filling can soften the puff pastry before it has a chance to bake properly.
Don’t overfill: Leave a little room at the top so the creamy filling doesn’t spill over the sides.
Use a muffin pan: It helps the pastry maintain its cup shape while baking.
Delicious Variations
Chicken and Mushroom Puff Pastry Cups
Add 1 cup cooked shredded chicken to the mushroom filling for a heartier appetizer.
Spinach and Mushroom Cups
Stir in 1 cup fresh chopped spinach after the mushrooms have cooked. Continue cooking until the spinach wilts.
Garlic Parmesan Mushroom Cups
Add an extra clove of garlic and increase the Parmesan to ½ cup for a richer garlic-cheese flavor.
Bacon Mushroom Cups
Cook and crumble 4 slices of bacon, then stir them into the finished mushroom filling.
Cheesy Mushroom Cups
Add ½ cup shredded mozzarella or Gruyère along with the Parmesan for an extra cheesy filling.
Make-Ahead Instructions
The mushroom filling can be prepared 1 day ahead and refrigerated in an airtight container.
When you’re ready to bake, assemble the pastry cups with the chilled filling and bake as directed.
For the best texture, assemble the puff pastry cups shortly before baking rather than letting filled pastry sit for several hours.
What to Serve With Them
These little pastry cups pair wonderfully with:
- Green salad
- Tomato soup
- Roasted vegetables
- Grilled chicken
- Fresh fruit
- Cheese and charcuterie boards
- A simple herb salad
They’re especially good as part of an appetizer platter alongside olives, cheese, crackers, and fresh vegetables.
Storage and Reheating
Store leftover pastry cups in an airtight container in the refrigerator for up to 3 days.
For the crispiest result, reheat them in a 350°F (175°C) oven for approximately 8–10 minutes.
An air fryer also works well. Reheat at 350°F (175°C) for about 4–6 minutes, checking frequently.
Avoid microwaving if possible because it can make the puff pastry soft.
