Instructions
1. Prepare the Crust
- Preheat your oven to 325°F (165°C).
- In a bowl, combine the crushed pistachios, crushed crackers, Parmesan, feta, melted butter, garlic powder, thyme, and black pepper.
- Press the mixture firmly into the bottom of a 9-inch springform pan lined with parchment.
- Bake for 10 minutes, then set aside to cool slightly.
2. Cook the Mushroom Mixture
- In a skillet, heat olive oil and butter over medium heat.
- Add the onions and sauté until soft and translucent.
- Add garlic and cook for 30 seconds.
- Add mushrooms, oregano, basil, salt, and pepper.
- Cook until mushrooms release their moisture and it evaporates (about 7–8 minutes).
- Stir in the chopped pistachios, remove from heat, and let cool.
3. Make the Cheesecake Filling
- In a mixing bowl, beat the cream cheese until smooth.
- Add ricotta/mascarpone, Parmesan, and feta; mix again.
- Add the eggs one at a time, mixing gently.
- Fold in the cooled mushroom mixture, parsley, chives, and lemon zest if using.
4. Assemble & Bake
- Pour the filling over the crust in the springform pan.
- Smooth the top with a spatula.
- Bake for 45–55 minutes, or until the center is mostly set but still slightly jiggly.
- Turn off the oven, crack the door open, and let the cheesecake cool inside for 1 hour to prevent cracking.
- Chill in the refrigerator for at least 4 hours or overnight for best texture.
