Savory Swiss Chard and Caramelized Onion Tart

Ingredients

• Salt (to taste)
• Black pepper (to taste)
• Gruyere cheese (1 cup, grated)
• Milk (1 cup)
• Eggs (3 large)
• Garlic (2 cloves, minced)
• Olive oil (2 tablespoons)
• Onions (2 medium, thinly sliced)
• Swiss chard (4 cups, chopped (stems removed))
• Pie crust (1 (9-inch) store-bought or homemade)

Instructions

1. Preheat the oven to 375°F (190°C).
2. Roll out the pie crust and gently press it into a 9-inch tart pan. Trim any excess crust, leaving a slight overhang for a rustic look.
3. In a large skillet, heat the olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, until the onions are caramelized and golden brown, about 15-20 minutes.
4. Add the minced garlic and chopped Swiss chard to the skillet. Cook for an additional 5 minutes, or until the chard is wilted and tender. Season with salt and black pepper to taste.
5. In a separate bowl, whisk together the eggs and milk until well combined. Add a pinch of salt and pepper if desired.
6. Spread the caramelized onion and Swiss chard mixture evenly over the prepared pie crust.
7. Pour the egg and milk mixture over the vegetable layer, ensuring an even distribution.
8. Sprinkle the grated Gruyere cheese generously on top of the tart.
9. Bake in the preheated oven for 30-35 minutes, or until the tart is set and the top is golden brown.
10. Allow the tart to cool for 5-10 minutes before slicing and serving. Enjoy warm or at room temperature!
