Step 1: Preheat Your Oven. Preheat your oven to 375°F (190°C) to ensure even baking.
Step 2: Sauté the Vegetables. Heat 1 tablespoon of olive oil in a skillet over medium heat. Sauté shallots for about 3 minutes until translucent, then add broccoli and 1 cup of water. Cook for another 4–5 minutes until broccoli is tender. Drain excess water and set aside.
Step 3: Whisk the Egg Mixture. In a large mixing bowl, whisk together eggs, milk, salt, and pepper until well combined.
Step 4: Combine Ingredients. Fold the sautéed vegetables into the egg mixture, adding cheese and thyme or chives. Stir gently to combine.
Step 5: Prepare the Pie Dish. Lightly grease your pie dish with olive oil to prevent sticking.
Step 6: Bake the Quiche. Pour the mixture into the prepared dish and bake for 30–35 minutes, until set and lightly golden.
Step 7: Cool and Serve. Allow the quiche to cool for a few minutes before slicing. Serve warm or refrigerate for later.
