Caramelized Onion and Sweet Potato Quiche

Caramelized Onion and Sweet Potato Quiche

Ingredients

• 2 T butter
• 2 T heat-safe oil (We used olive oil.)
• 3 cups chopped onions (about 2 large)
• 2 cups sweet potatoes, peeled and diced into 1/2-inch cubes
• 2 cups chopped fresh baby spinach, chard, kale (stems removed), or other greens
• 4  eggs
• 1 cup milk
• 1/2 cup half-and-half or cream
• 1/2 tsp Kosher salt
• dash black pepper (to taste)
• 1 1/2 tsp Herbs de Provence (or another herb blend like Italian seasoning)
• 1 T flour
• 1/2 cup shredded fresh Pecorino-Romano or Parmesan cheese
• 1/2 cup Swiss or Gruyere cheese

• 1 9-inch pre-baked pie crust

Directions

1. Add oil and butter to a large skillet over medium-high heat. Add onions and cook for about 5 minutes until onions soften and turn translucent. Reduce heat to medium-low, cover, and cook onions for about 20-25 minutes, stirring occasionally, until deep golden brown.
2. Add cubed sweet potatoes and spinach to skillet. Cook for 3-4 minutes until spinach is wilted. Remove from heat and set aside to cool.
3. Preheat oven to 325 degrees F.
4. In a large mixing bowl whisk together eggs, milk, cream, salt, pepper, and herbs. In a small bowl combine the cheeses with the flour, tossing until combined, then put cheese/flour mixture into the large bowl with the egg mixture; add also the onion mixture (when it has cooled enough to not scramble the eggs, slightly warmer than room temperature). Stir everything together until combined, then pour into the pre-baked pie crust.
5. Bake for about 40 minutes or until a knife inserted into the quiche comes out clean and it doesn't jiggle when you nudge the pan.
6. Makes 6-8 Servings

It made to much for one pie but not enough for two pies. So next time I need less of the recipe or a bigger pie crust.
