1. Gather ingredients: To make your own Egg McMuffin, you will need an English muffin, one large egg, a slice of ham, a slice of American cheese, butter, salt, and pepper.

2. Preheat your oven: Set your oven to 350°F (175°C) and let it preheat while you prepare the rest of the ingredients.

3. Toast the English muffin: Cut the English muffin in half and place it on a baking sheet. Put it in the preheated oven for about 5 minutes or until lightly toasted.

4. Cook the ham: In a skillet over medium heat, cook the slice of ham for about 3-4 minutes on each side until heated through and slightly browned. Remove from the skillet and set aside.

5. Prepare the egg: Crack the egg into a small bowl or ramekin that’s roughly the same diameter as your English muffin. Season with a pinch of salt and pepper.

6. Cook the egg: Place the bowl with the egg in the microwave for approximately 60 seconds on high power. It’s important to keep an eye on it – you’re looking for a cooked egg that’s still soft in the center.

7. Assemble your Egg McMuffin: Spread a small amount of butter on both sides of the toasted English muffin. Place the cooked ham on the bottom half, followed by the cooked egg, and top it off with a slice of American cheese.

8. Final Toast: Place your assembled Egg McMuffin on the baking sheet in the preheated oven for an additional 1-2 minutes or until cheese is melted.

9. Close and serve: Remove your completed Egg McMuffin from the oven, place the top half of the toasted English muffin over it and press down slightly.

10. Enjoy: Your delicious homemade Egg McMuffin is now ready to enjoy! Serve immediately with your favorite breakfast sides or wrap it in some foil for an on-the-go meal.
