Follow these simple steps to create your Hash Brown Egg Cups:

1. Preheat the Oven: Preheat your oven to 375°F (190°C). This ensures that your cups cook evenly.
2. Prepare the Muffin Tin: Grease a muffin tin with cooking spray or oil. This will help prevent sticking.
3. Mix Hash Browns: In a mixing bowl, combine the thawed hash browns with salt, pepper, and a sprinkle of cheese.
4. Form Cups: Press the hash brown mixture into the bottom and up the sides of the muffin tin cups, forming nests. Make sure they are even to cook well.
5. Bake Hash Brown Nests: Place the muffin tin in the oven and bake for about 15 minutes, until the hash browns are golden and crispy.
6. Prepare Egg Mixture: In another bowl, whisk together the eggs and milk. Season with salt and pepper.
7. Add Vegetables and Cheese: Fold in your desired vegetables and remaining cheese into the egg mixture.
8. Fill Hash Brown Cups: Remove the muffin tin from the oven. Carefully pour the egg mixture into each hash brown cup, filling them just to the top.
9. Bake Again: Return the muffin tin to the oven and bake for an additional 15-20 minutes, or until the eggs are set.
10. Cool and Serve: Remove from the oven and let cool for a couple of minutes. Use a spoon to gently lift each cup out of the tin. Serve warm.
