Cheesy Mushroom Puff Pastry Bites Recipe
Ingredients
- Nonstick cooking spray
- 1 tablespoon olive oil
- medium onion, diced
- 8 ounces baby bella mushrooms, chopped
- 2 cloves garlic, minced
- Freshly cracked salt and black pepper, to taste
- 1 sheet frozen puff pastry, thawed
- 2 ounces Gruyre cheese, shredded
- 1 tablespoon grated Parmesan cheese
- teaspoon dried thyme
Directions
Step 1: Preheat the oven to 375F (190C). Lightly spray the cups of two 12-cup mini muffin pans with nonstick cooking spray.
Step 2: In a skillet, heat olive oil over medium heat. Add diced onion and cook for about 3 minutes, until the edges begin to brown and caramelize.
Step 3: Add chopped mushrooms and minced garlic to the skillet. Cook until the mushrooms soften, and season with salt and pepper to taste.
Step 4: Using a slotted spoon, transfer the cooked vegetables onto a paper towel-lined plate to drain any excess moisture.
Step 5: On a lightly floured cutting board, roll out the puff pastry sheet into a horizontal rectangle. Use a pizza slicer to cut the pastry into 24 (2 -inch) squares by cutting 4 rows horizontally and 6 rows vertically.
Step 6: Gently press each pastry square into the cups of the mini muffin pans. Use a fork to prick each square, creating small holes in the dough.
Step 7: Spoon an equal portion of the mushroom mixture into each pastry cup.
Step 8: Top each bite with shredded Gruyre cheese, grated Parmesan cheese, and a pinch of dried thyme.
Step 9: Place the muffin pans in the preheated oven and bake for about 15 minutes, or until the pastry puffs up and the edges turn golden brown.
Step 10: Allow the bites to cool for a few minutes in the pans on a wire rack before transferring them to a serving dish. Serve warm and enjoy!
Cook's Note
If you prefer, you can substitute fresh thyme leaves instead of using dried thyme for a fresher flavor.

History of Cheesy Mushroom Puff Pastry Bites
The origin of puff pastry dates back to ancient times, with early versions appearing in the kitchens of the French and Italian courts. The idea of folding dough with butter to create a flaky, layered pastry was refined during the Renaissance. However, it was in the 17th and 18th centuries in France where puff pastry as we know it today was perfected. The addition of mushrooms and cheese to puff pastry likely evolved as an attempt to create flavorful, savory snacks that would suit various occasions, from family dinners to elegant parties.
Regional Variations
While puff pastry is widely used across many cuisines, the pairing of mushrooms and cheese is particularly popular in European cooking, especially in France, Italy, and Spain. In these countries, mushrooms like cremini, button, and wild varieties are often combined with cheeses such as Gruyre, Brie, and Parmesan. Each region adds its own twist depending on local flavors and ingredient availability. For example, in the French tradition, puff pastry might be used in a more elaborate entre, while in Spain, smaller, bite-sized versions like these are perfect as tapas.
How Does It Differ from Similar Dishes?
Cheesy Mushroom Puff Pastry Bites stand out from similar dishes like quiches, savory pastries, or stuffed mushrooms due to their use of delicate puff pastry, which provides a crisp, flaky texture. Unlike quiches, which are more egg-based and custardy, these bites focus on the savory mushroom-onion filling complemented by melted cheeses. The mini muffin pan shape makes them bite-sized and perfect for parties or casual gatherings, differentiating them from larger, more formal pastries.
Where Are They Typically Served?
These delicious appetizers are typically served as a starter at dinner parties, holiday gatherings, or cocktail events. They are also a great addition to a buffet table, where their small size makes them easy to eat in one or two bites. In Europe, particularly in France and Spain, they are a popular choice for tapas-style meals or as part of a more extensive hors d'oeuvre spread. Due to their versatility and rich flavor, they can be served warm or at room temperature, making them ideal for outdoor gatherings, like picnics or garden parties.
