- Cooking spray
- 1 cup fresh or frozen shredded russet potato
- 2 tablespoons butter
- ½ cup diced onion
- 1 clove garlic, minced (about 1 teaspoon)
- 1 bunch Swiss chard, stemmed and finely chopped
- 7 large eggs
- ¾ cup plain Greek yogurt
- 1 tablespoon flaxseeds
- ¼ teaspoon salt
- 3 or 4 large fresh basil leaves
- ½ teaspoon chopped fresh rosemary leaves
- ½ cup loosely packed fresh parsley leaves
- 1 tablespoon chopped fresh chives
- 1 cup shredded Swiss cheese
Preheat the oven to 350°F. Coat a standard nonstick muffin tin with cooking spray.
Rinse the shredded potato in a sieve and squeeze all the moisture out by hand.
In a large sauté pan, melt the butter over medium-high heat. Add the onion, potato, and garlic. Cook, stirring occasionally, until the onion is soft and the potato starts to color, 4 to 5 minutes. Add the chard and sauté until wilted, about 1 minute. Remove from the heat.
In a blender, combine the eggs, yogurt, flaxseeds, salt, basil, rosemary, parsley, and chives and pulse until the mixture is smooth and green.
Divide the vegetable mixture among the cups of the prepared muffin tin, filling each about halfway. Pour the egg mixture on top of the vegetables, filling each muffin cup about three-quarters full. Give the contents of each muffin cup a quick stir to make sure the egg and veggies are combined.
Bake until the egg is completely set and no longer wet on top, 12 to 15 minutes, then carefully remove the pan from the oven and sprinkle each mini-frittata with about 2 tablespoons of the cheese. Bake for 3 minutes more to melt the cheese, then remove from the oven.
Serve the frittatas hot from the oven, but they are also amazing (and so portable!) at room temperature.
