Making Spinach Egg Muffins with Cheese is straightforward and requires only a few steps. Simply follow this guide:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C) and greasing a muffin tin with cooking spray or oil.
2. Prepare the Spinach: In a skillet over medium heat, lightly sauté the chopped spinach until wilted. This step helps to enhance its flavor and reduce excess moisture.
3. Mix Eggs and Ingredients: In a large mixing bowl, crack the eggs and whisk them together. Add the milk, salt, pepper, garlic powder, and onion powder. Mix until the ingredients are perfectly combined.
4. Incorporate Cheese and Spinach: Stir in the cooked spinach and cheese into the egg mixture. Ensure it’s well-mixed for even distribution.
5. Fill Muffin Tin: Pour the egg mixture into the prepared muffin tin, filling each cup about ¾ full to allow space for the muffins to rise.
6. Bake: Place the muffin tin in the preheated oven, and bake for 20-25 minutes or until the muffins are set and slightly golden on top.
7. Cool and Remove: Once baked, let the muffins cool in the tin for a few minutes before gently removing them to a wire rack.

These steps will lead you to create scrumptious Spinach Egg Muffins that can be enjoyed any time of the day.
