Rich egg custard combined with potatoes and bacon make this casserole an easy brunch winner.
1. Preheat the oven to 400 degrees F and lightly coat a 9 x 13-inch baking dish with cooking spray.
2. Toss the potatoes with the olive oil, 1/2 teaspoon salt, and 1/2 teaspoon pepper to coat, then place on a baking sheet. Roast for 30 minutes, until lightly browned. Remove the potatoes and lower the oven temperature to 350 degrees F.
3. In a medium skillet, melt the butter over medium heat, then add the onion and garlic and cook until softened.
4. In a large bowl, beat the eggs and milk. Add the cooked potatoes, sautéed onion, bacon, cheese, and cayenne and season with salt and pepper.
5. Pour into the baking dish and bake for 25 minutes, until the egg custard is set. Sprinkle with thyme and serve.
