Bake a dozen on Sunday, eat them all week. These spinach and cheese egg muffins are the low carb lunch prep hack that busy people actually stick with.
Preheat your oven to 350°F and grease a 12-cup muffin tin lightly with olive oil for easy removal.
Heat a skillet over medium heat, add olive oil, and sauté fresh spinach for 2–3 minutes until wilted but still bright green. Remove from heat and let cool slightly.
In a large bowl, whisk together eggs, milk, salt, and black pepper until well mixed and slightly frothy for even texture.
Add cooked spinach, shredded cheddar cheese, and green onions to the egg mixture. Gently fold with a spatula to distribute ingredients uniformly.
Portion the mixture evenly into the muffin tin cups, filling each about 3/4 full. Bake in the preheated oven for 18–20 minutes, or until the egg muffins are set and lightly golden around the edges.
Let the muffins cool in the pan for 3 minutes before loosening with a small spatula. Serve immediately or cool completely before refrigerating for meal prep.
