Instructions

  1. Step 1: Preheat oven to 375°F. Toss diced beetroots with 1 tbsp olive oil and roast on a parchment-lined baking sheet for 25 minutes until tender and slightly caramelized, stirring once halfway through.
  2. Step 2: In a medium bowl, whisk flour, 1/4 tsp salt, and 1 tbsp thyme leaves. Cut in cold butter until mixture resembles coarse crumbs, then add ice water and mix until dough just holds together. Form into a disk, wrap in plastic, and refrigerate for 30 minutes.
  3. Step 3: Roll dough into a 12-inch circle on a floured surface. Arrange roasted beetroots and apple slices in the center, leaving a 2-inch border. Sprinkle with lemon zest and 1 tbsp thyme, then drizzle with maple syrup.
  4. Step 4: Fold the dough edges over the filling, pleating as you go. Brush the crust with remaining 1 tbsp olive oil and bake for 35-40 minutes until golden brown and the filling is bubbling.
