1-First Step: Preheat and Prepare Muffin Tin Preheat your oven to 400°F (200°C). Line a 12-cup muffin pan with silicone liners or grease it well with non-stick spray or oil to prevent sticking.

2-Second Step: Whisk Eggs and Seasonings In a large bowl, vigorously whisk together the eggs, sea salt, black pepper, garlic powder, and dried basil until fully combined and slightly frothy for a light texture.

3-Third Step: Incorporate Spinach and Cheese Stir in the chopped fresh spinach and grated Parmesan cheese evenly into the egg mixture. For added flavor and texture, fold in cooked crumbled bacon if desired.

4-Fourth Step: Fill Muffin Cups Divide the mixture evenly among the prepared muffin cups, filling each about two-thirds full. Optionally, sprinkle extra grated cheese atop each muffin for a golden, cheesy crust.

5-Fifth Step: Bake Muffins Bake in the preheated oven for 12 to 15 minutes, or until the muffins are fully set and lightly golden on top. A toothpick inserted into the center should come out clean.

6-Final Step: Cool and Store Allow the muffins to cool for a few minutes before removing from the pan. Serve warm or at room temperature. Store leftovers in an airtight container in the refrigerator for up to 4 days or freeze individually wrapped for up to 3 months. To reheat, microwave for 30-40 seconds or warm in an air fryer or oven at 375°F (190°C) for about 5 minutes.
