01 - Preheat oven to 350°F. Line an 8-inch springform pan with parchment paper.
02 - Pulse crackers in a food processor until fine crumbs form. Mix in melted butter and 1/2 tsp sea salt until combined. Press mixture firmly into the bottom of the prepared pan. Bake for 10 minutes, then set aside to cool.
03 - In a large bowl, beat cream cheese, ricotta, and grated cheese until completely smooth. Add eggs one at a time, mixing thoroughly after each addition. Fold in thyme, lemon zest, black pepper, and salt until evenly distributed.
04 - Pour filling over the cooled crust and smooth the top surface. Bake for 40-45 minutes until the center is just set with a slight wobble. Cool to room temperature, then refrigerate for at least 2 hours or preferably overnight.
05 - Increase oven temperature to 400°F. Toss beetroot wedges with olive oil, balsamic vinegar, salt, and pepper. Arrange on a roasting tray and roast for 30-35 minutes until tender and caramelized. Allow to cool slightly before serving.
06 - Release cheesecake from the springform pan. Arrange roasted beetroot wedges on top. Scatter fresh chives and microgreens over the surface. Drizzle with extra virgin olive oil. Slice and serve chilled or at room temperature.
