Spicy, tender arugula brings pleasant bite to this baked dish with savory sausage and potato rounds.
8 ounces breakfast sausage
½ pound Sieglinde potatoes, washed and thinly-sliced into rounds
4 cups packed arugula
½ cup Grana-style cheese, grated
¼ cup milk
2 tablespoons olive oil
Sea salt and fresh ground pepper
1. Preheat oven to 350°. In a large bowl, lightly whisk together the eggs, cheese, milk, salt and pepper. Set aside.
2. In an ovenproof fry pan over medium-high heat, warm 1 tablespoon of the olive oil. Toss potato rounds into the pan and sauté until tender, seasoning generously with salt and pepper Add sausage meat to pan and cook, breaking up the meat into small pieces, until nicely browned and cooked, 3-4 minutes. Add the arugula and stir just until evenly wilted, about 1 minute. Add the sausage-potato mixture to the bowl with the egg mixture.
3. Wipe the pan clean and return it to medium-high heat. Add the remaining 1 tablespoon olive oil and spread to coat the pan bottom. When the oil is hot, pour the egg mixture into the pan and smooth the top, making sure the potato slices lay flat.
4. Transfer the pan to the oven and bake until the frittata is set in the center and slightly puffed, 25 to 30 minutes. Let cool for 5 minutes in the pan. Carefully run a paring knife or sharp-bladed spatula around the inside edges to release the frittata. Cut into wedges and serve warm or at room temperature.
