- 5 ounces (about 8 cups) fresh baby spinach, coarsely chopped
- 6 large eggs
- ¼ cup whole milk
- ¼ cup half-and-half
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh thyme leaves (plus more for garnish)
- ¼ teaspoon salt
- ¼ teaspoon ground pepper

Instructions
- Preheat the Oven
- Preheat your oven to 375°F (190°C).
- Grease a 9-inch pie pan with cooking spray and set it aside.
- Cook the Vegetables
- Heat olive oil in a large nonstick skillet over medium-high heat. Swirl to coat the pan evenly.
- Add mushrooms and cook, stirring occasionally, for about 8 minutes until browned and tender.
- Add onion and garlic, stirring and cooking for 5 minutes until softened.
- Toss in the spinach and cook for 1–2 minutes until wilted. Remove from heat and let cool slightly.
- Prepare the Egg Mixture
- In a medium bowl, whisk together eggs, milk, half-and-half, Dijon mustard, thyme, salt, and pepper until well combined.
- Fold in the sautéed vegetables and shredded Gruyère cheese.
- Assemble the Quiche
- Pour the egg mixture into the prepared pie pan, spreading it evenly.
- Bake for 30 minutes, or until the quiche is set and golden brown on top.
- Cool and Serve
- Allow the quiche to cool for 10 minutes before slicing.
- Garnish with fresh thyme and serve warm.
Notes
- Cheese Alternatives: If Gruyère isn’t available, use cheddar, mozzarella, or Swiss cheese.
- Crust Option: Add a pre-baked pie crust for a more traditional quiche or go crustless for a low-carb version.
- Make-Ahead: Prepare the quiche a day in advance and reheat in a 325°F oven for 15 minutes before serving.
