Ingredients

• 1 teaspoon salt
• 12 eggs
• salt and ground black pepper to taste
• 1 onion, diced
• 1 cup mascarpone cheese
• 3 tablespoons olive oil, divided, or more as needed
• 4 cups sweet potato slices, 1/2-inch thick
• 2 cups cooked mixed vegetables, chopped
• ½ cup diced scallions, green parts only

Recipe Instructions

Step 1

Preheat the oven to 300 degrees F (150 degrees C).

Step 2

Add 2 tablespoons oil to a frying pan over medium heat. Cook sweet potatoes and salt until starting to brown, 5 to 10 minutes, adding more oil if necessary. Transfer to an 11 x 7-inch rectangular glass baking dish. Press sweet potatoes into the bottom to form a compact layer.

Step 3

Add 1 tablespoon oil to the frying pan and cook onion over medium heat until translucent, about 3 minutes. Add cooked mixed vegetables, season with salt and pepper, and cook until slightly browned, 5 to 10 minutes. Transfer to the baking dish with the sweet potatoes.

Step 4

Beat eggs in a blender until just blended, then add mascarpone cheese. Beat until mascarpone cheese starts to separate into smaller bits, about 1 minute more; it won't fully blend. Pour over the vegetables in the baking dish. Top with chopped scallions and mix them in slightly.

Step 5

Bake quiche in the preheated oven until set and slightly browned, 55 to 75 minutes.
