Printable Recipe

4 large red-skinned potatoes or Yukon gold potatoes, diced
4 Tbsp olive oil
2 garlic cloves, minced
4 scallions, white and green parts finely chopped
1 medium green bell pepper, seeded and finely diced
1 medium red bell pepper, seeded and finely diced
5 large eggs
1/2 cup sour cream
1 cup grated Parmigiano-Reggiano or Spanish Rocal cheese
3 Tbsp snipped fresh chives (or about 1 tsp dried chives if you can't find the fresh)
Kosher salt and fresh black pepper, to taste

Preheat oven to 375˚F.

Place diced potatoes in a sauce pan and cover with cold water. Bring to a boil, then reduce heat to low and cook for 5-7 minutes, until the potatoes are tender. Drain and set aside to slightly cool.

Spray a casserole dish (approximately 7x10 inch) with cooking spray; set aside.

Place the 4 Tbsp olive oil, garlic, scallions and bell peppers in a skillet and cook over medium heat, stirring, for 5-6 minutes, or until the onions are softened but not browned. Let cool a bit, then stir in the cooked potato.

In a large bowl, beat the eggs, sour cream, cheese and chives together. Stir in the vegetable-potato mixture, and season to taste with salt and pepper.

Pour the mixture into the baking dish and smooth the top. Bake for 40 minutes, or until golden brown, puffed, and set in the center. Remove from the oven and let cool and set. Run a spatula around the edge, then invert onto a cutting board, browned-side up. If the surface looks a little runny, place it under the broiler to dry out. (I didn't need to do this.)

Let cool completely. Neaten the edges, if necessary, then cut into one-inch squares. Serve on a platter with wooden toothpicks.
