How to Make Luxe Mushroom & Thyme Puff Squares
Start by preparing your ingredients: Gather all your items on the counter so you’re ready to go without scrambling later.
Sauté the Aromatics: In a skillet over medium heat, melt butter until bubbly. Add diced onions and minced garlic; cook until onions are translucent and fragrant.
Add the Mushrooms: Toss in your sliced mushrooms and fresh thyme. Sauté until mushrooms release moisture and turn golden brown—about 5 to 7 minutes.
Season to Perfection: Stir in salt, pepper, and any additional herbs you love (like rosemary for an extra kick). Let that mixture cool slightly while prepping the pastry.
Roll Out the Pastry: On a floured surface, roll out your puff pastry until it’s about 1/8 inch thick. Cut into squares—aim for about 4 inches each so they’re perfectly bite-sized.
Assemble Your Squares: Place a spoonful of the mushroom filling onto one half of each square. Brush edges with egg wash before folding over to create little pockets of goodness. Seal edges well by pressing with a fork.
Bake Until Golden: Preheat your oven to 400°F (200°C). Arrange squares on a baking sheet lined with parchment paper and brush tops with more egg wash. Bake for 20-25 minutes or until puffed and golden brown.
And there you have it! Your Luxe Mushroom & Thyme Puff Squares are ready to be devoured by you and anyone lucky enough to be nearby! Enjoy every flaky bite as you bask in culinary glory!
