Recipe yields 6 servings
2 tbsp unsalted butter
1 medium yellow onion
1 large bunch Swiss chard
8 large eggs
1/2 cup shredded mozzarella cheese
Salt & ground black pepper, to taste
Preheat the oven to 400F degrees. Slice the onions.
Roughly chop the Swiss chard. Rinse it off and dry it.
To a large skillet, melt your butter and add your sliced onions. Cook on medium-low heat so the onions caramelize and really get a nice flavor without burning.
Add the Swiss chard on top of the onions and stir until they wilt down to about half the original size.
In a mixing bowl, combine your eggs, cheese and some salt and pepper. Whisk it all together.
Pour the egg mixture right over your vegetables. Cook for 5-6 minuntes on medium heat until the edges have set but the top is still a bit runny.
Place the pan right into the oven (make sure your using an oven safe pan!) and cook for an additional 5 minutes to set the top. You will see it really puffs up nice when you pull it from the oven.
Slice the fritatta and serve with some toasty bread. A great way to start the morning with some healthy greens. Enjoy!
