Step 1: Prepare the Mushroom Mixture
Heat olive oil in a large skillet over medium-high heat.
Add diced onions and cook for 3–4 minutes until softened.
Stir in garlic and cook for 30 seconds.
Add mushrooms and sauté for 8–10 minutes until golden brown and most of the moisture has evaporated.
Season with:
- Salt
- Pepper
- Smoked paprika
- Fresh thyme
Cook for another 2 minutes.
Remove from heat and cool slightly.

In a large bowl combine:
- Cottage cheese
- Greek yogurt
- Mozzarella cheese
- Parmesan cheese
Mix until smooth and creamy.
Fold in:

Taste and adjust seasoning if necessary.
The filling should be thick, creamy, and packed with savory flavor.
Step 3: Prepare the Puff Pastry
Preheat oven to 400°F (200°C).
Line a baking tray with parchment paper.
Roll puff pastry slightly to smooth seams.
Cut into 6 equal squares.
Using a knife, score a border around each square, leaving a ½-inch edge.
Do not cut all the way through.
Prick the center area with a fork several times.
Step 4: Fill the Tartlets

Spoon the mushroom protein filling into the center of each pastry square.
Avoid overfilling.
Leave the scored border exposed.
Step 5: Egg Wash
Whisk together:

Brush around pastry edges.
This creates the beautiful golden bakery-style finish.
