Instructions

  1. Step 1: Preheat oven to 350°F. Grease a 6-cup muffin tin with 1 tbsp butter to prevent sticking.
  2. Step 2: In a large bowl, whisk 6 large eggs with 2 tbsp heavy cream until fully combined and slightly frothy. Stir in 1 cup chopped fresh spinach, 1/2 cup shredded cheddar cheese, 1/2 tsp salt, and 1/4 tsp black pepper until evenly distributed.
  3. Step 3: Pour the egg mixture evenly into the prepared muffin cups, filling each about 3/4 full. Bake for 18-20 minutes until the egg muffins are set and slightly golden on top.
  4. Step 4: Let cool 5 minutes before removing from the tin. Serve warm or refrigerate for a quick keto-friendly breakfast throughout the week.
