Fluffy, protein-packed egg bites baked in a muffin pan and easy to customize with your favorite mix-ins. Perfect for meal prep breakfasts, snacks, or a grab-and-go option.
Preheat oven to 325°F. Lightly grease a 12-cup muffin tin with neutral oil or use silicone liners.
In a large bowl, whisk the eggs, milk, salt, and pepper until very smooth and slightly frothy.
Stir in the cheddar, bell pepper, spinach, and green onions. If using bacon, fold it in now or sprinkle some into each cup.
Divide the mixture evenly among the 12 muffin cups, filling each about 0.75 full.
Bake for 18 to 22 minutes, until the centers are just set and no longer glossy. Do not overbake to keep them tender.
Cool in the pan for 5 minutes, then run a thin knife around the edges and lift out. Serve warm.
Store leftovers in an airtight container in the refrigerator for up to 4 days, or freeze for up to 2 months. Reheat in the microwave until warm.
Notes
Customize with cooked sausage, ham, or swap cheddar for pepper jack or feta. Add mushrooms, broccoli, or tomatoes (pat very dry). For dairy-free, use unsweetened almond milk and skip the cheese. For extra silky texture, blend the egg mixture for 20 seconds before baking.
