Detailed Instructions
- 1. Preparation Phase:
- Preheat oven to 350°F. Grease standard 12-cup muffin tin with olive oil spray. Chop vegetables uniformly - small pieces ensure even distribution. Heat olive oil in large skillet over medium heat.

- Bake 20-25 minutes until eggs are set and tops are lightly golden. Test with toothpick - should come out clean. Let cool in pan 5-10 minutes before removing.

Storage and Serving Solutions
Proper storage ensures these egg cups remain fresh and delicious. Store cooled egg cups in an airtight container in the refrigerator for up to five days. For longer storage, freeze individually wrapped cups for up to three months. When ready to enjoy, thaw overnight in the refrigerator. Reheat gently in the microwave for 20-30 seconds or in a 350°F oven until warmed through.
Perfect Pairings
These protein-packed egg cups pair beautifully with morning favorites. Serve alongside fresh fruit salad, whole grain toast, or Greek yogurt parfait. For brunch gatherings, create a spread with avocado toast, roasted potatoes, and fresh orange juice. A hot cup of coffee or herbal tea complements the savory flavors perfectly.
