Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 375°F (190°C). Prepare a 12-cup muffin tin by greasing it thoroughly or using silicone liners to prevent sticking.
Step 2: Sauté Vegetables
If you are using mushrooms, onions, or spinach, heat a small amount of oil in a pan over medium heat. Add the chopped vegetables and sauté for 3–4 minutes, stirring occasionally, to soften them and reduce moisture, which helps to prevent sogginess in the muffins.
Step 3: Whisk the Eggs
In a large mixing bowl, crack the 8 large eggs and add 1/4 cup of milk along with salt and pepper to taste. Whisk everything together until the mixture is well combined and slightly frothy.
Step 4: Combine Ingredients
Add the sautéed vegetables, 1/2 cup of diced bell peppers, 1/2 cup of chopped spinach (whether fresh or thawed from frozen), 1/4 cup of diced onion, and 1/2 cup of chopped mushrooms to the egg mixture. Also, add 1/2 cup of shredded cheddar cheese and any optional ingredients you desire, mixing gently until everything is evenly distributed.
Step 5: Fill the Muffin Tin
Carefully pour the egg and vegetable mixture into the prepared muffin tin, filling each cup approximately 3/4 full to allow for rising during baking.
Step 6: Bake the Muffins
Place the muffin tin in the preheated oven and bake for 18–22 minutes. The muffins are done when the tops are set, lightly golden, and a toothpick inserted into the center comes out clean.
Step 7: Cool and Remove
Once baked, let the muffins cool in the tin for about 5 minutes. Carefully remove them from the tin and allow them to cool further on a wire rack or a plate.

Whisking Eggs
Ensure the eggs are well combined with milk and seasonings for a fluffy texture. Whisk vigorously until the mixture is uniform in color and slightly frothy.
