Ingredients

1 lb spaghetti

¼ cup (½ stick) unsalted butter

1 large (or 2 small) Vidalia onion, thinly sliced (about a cup)

3 cups fresh spinach, packed

1 cup smoked gouda, grated

10 eggs

kosher salt and freshly ground pepper, to taste

Preparation

Cook spaghetti according to package directions, until al dente. Drain through a colander. Preheat oven to 350°F. In a large cast iron skillet (or a large ovenproof, nonstick sauté pan), melt unsalted butter over medium-low heat. Add sliced onion, season with salt and pepper, and cook until onions are soft, about 6 minutes. Add fresh spinach, toss to wilt the spinach, then stir in the cooked spaghetti and 1 cup grated smoked gouda. Whisk together 10 eggs, salt and pepper and pour over the spaghetti mixture. Bake at 350°F until the eggs are set, about 20 minutes. Cool slightly, then cut into wedges to serve.
