- Prep Time : 15 min
- Cook Time : 30 min
- Ready Time : 45 min
- 1 red potato, diced
- 1 tablespoon olive oil
- 1 small yellow onion, thinly sliced
- 1 clove garlic, minced
- 1 bunch Swiss Chard, leaves removed and roughly chopped
- 8 eggs
- pinch salt
- black pepper, to taste
- 1/2 cup grated sharp cheddar cheese
- 1/4 cup grated parmesan cheese
- 1 tablespoon butter
The ingredients in this one are classic: some cooked-down greens with a little onion and garlic, cubed potato, and shredded cheddar cheese to add a salty tang. I like to use a small pan to make the frittata taller, finishing it in the oven; by the time the center is solid, the sides develop a crusty, caramelized edge. But it can also be spread out in a larger skillet and cooked under a broiler to speed things along.
Preheat the oven to 400°F. Put the diced potato in a small bowl, cover with a plate, and microwave on high for 3 to 4 minutes, until tender when pierced with a fork.
In a large (12-inch) skillet, heat the olive oil over medium heat until shimmering. Add the onion and cook until softened, about 3 minutes, then add the garlic and cook for a minute more. Add the chard and a splash of water, cover, and cook until the chard is completely soft. Add more water if necessary if the skillet is too dry and the chard is still tough. Before proceeding, cook off any leftover moisture, and allow to cool.
In a large bowl, whisk the eggs with the salt and cheeses, then stir in the chard and onion mixture and the potatoes.
Heat the butter in a medium skillet or small pan over medium heat until foaming, then add the egg mixture. Cook until the bottom and sides begin to set, then transfer to the oven and continue cooking until the center is solid, 5-15 minutes depending on the shape of the pan. Allow to cool somewhat before serving.
