Instructions

  1. Step 1: Preheat the oven to 350°F (175°C). Lightly grease a 6-cup muffin tin with 1 tsp olive oil.
  2. Step 2: In a mixing bowl, whisk together 6 large eggs and 1/4 cup heavy cream until smooth and slightly frothy.
  3. Step 3: Stir in 1 cup chopped fresh spinach, 1/2 cup shredded sharp cheddar cheese, 3 slices cooked and crumbled bacon, 1/2 tsp salt, and 1/4 tsp black pepper until evenly distributed.
  4. Step 4: Pour the egg mixture evenly into the 6 muffin cups, filling each about 3/4 full.
  5. Step 5: Bake in the preheated oven for 18-20 minutes, or until the egg muffins are set and a toothpick inserted in the center comes out clean.
  6. Step 6: Remove from oven and let cool for 5 minutes before carefully removing the muffins from the tin. Serve warm or store in the refrigerator for a quick grab-and-go breakfast.
