Instructions
Preheat oven to 350°F.
Spray a 12-count muffin pan generously with nonstick cooking spray, or line with silicone baking cups.
Whisk together eggs, milk, and a pinch of salt and pepper in a large bowl until smooth and well combined.
Divide your cooked fillings (veggies, meats, and/or cheese) evenly among the muffin cups as desired.
Pour the egg mixture into each cup, filling about 3/4 full.
Bake for about 20 minutes, or until eggs are fully set and a toothpick inserted in the center comes out clean. The tops will be lightly puffed and the edges will start pulling away from the pan.
Cool in the pan for 2 minutes. Gently slide a thin knife around the edges of each muffin and pop out.
Notes
Pan prep is key. Eggs stick to standard muffin tins, so spray generously with nonstick cooking spray. Silicone baking cups give the cleanest release.
Cook fillings first. The short bake time won't cook raw vegetables or meats. Saute veggies until softened and use fully cooked meats.
Don't overfill. The eggs puff up during baking, so fill each cup only about 3/4 full to prevent overflow.
Don't overbake. Remove from the oven as soon as centers are set. Overbaking makes egg muffins dry or rubbery.
Dairy-free option. Substitute plain unsweetened almond milk, oat milk, or any milk alternative. The small amount won't noticeably change flavor or texture. Skip the cheese or use a dairy-free shredded cheese.
Mini muffin pan. These work in a mini muffin pan too. Reduce bake time to about 8 to 10 minutes and check early.
Meal prep. Bake a full batch on the weekend for easy weekday breakfasts. Store in the fridge for up to 3 to 4 days.
Freezing. Cool completely, wrap individually in wax paper or parchment, and store in a freezer bag for up to 3 months.
Reheating from fridge. Wrap in a damp paper towel and microwave on 50% power for about 1 minute.
Reheating from frozen. No need to thaw. Wrap in a damp paper towel and microwave on 50% power for about 2 minutes. For a batch, reheat on a baking sheet at 325°F for 10 to 15 minutes.
