2 tbsp olive oil

Preheat the oven to 400\u00b0F. Grease a deep 10-inch quiche pan. Roll out the pie crust and press into the pan. Line with parchment paper and pie weights. Bake for 10-12 mins, until pastry is cooked but still light in color.
Heat the oil and butter in a large skillet on medium-low heat. Cook the onions, stirring, until tender, light brown and beginning to caramelize. Stir in the thyme leaves. Set aside.
Whisk the cream and eggs in a large bowl and season. Stir in the cheese. Spread onion mixture in the crust. Pour the egg mixture on top.
Bake for 30 to 35 mins, until golden brown. Serve warm or at room temperature. Garnish with microgreens, if desired.
