How to Make Cheesy Baked Egg Muffins

Step 1 - Preheat and prep the pan: Set your oven to 350 degrees F and allow it to fully preheat before the muffins go in. While it heats, grease a standard 12-cup muffin tin generously with butter or non-stick spray, covering every surface including the rims. If you are using silicone muffin cups, place them on a flat baking sheet for stability — silicone bends when full of liquid and a baking sheet underneath prevents spills.

Step 2 - Cook the bacon: Cook the bacon strips in a skillet over medium heat until crisp, then transfer to a paper towel-lined plate to drain. Once cool enough to handle, chop the bacon into small pieces. Pre-cooking the bacon before it goes into the muffin cups is essential — raw bacon releases a large amount of fat and water during baking, which will pool at the bottom of the cups and prevent the egg mixture from setting properly.

Step 3 - Whisk the egg mixture: Crack all twelve eggs into a large mixing bowl or a blender, add the milk, garlic powder, smoked paprika, salt, and pepper, and whisk vigorously until the yolks and whites are completely combined and slightly frothy. If you have a blender, this is the step where it pays off — blending the eggs on high for thirty seconds incorporates air into the mixture, which contributes to a lighter, fluffier texture once baked. Stir in half of the shredded cheddar and reserve the remaining half for topping.

Step 4 - Fill the cups: Distribute the chopped bacon, diced bell pepper, and green onions evenly among the twelve muffin cups, filling each about one-quarter of the way. Then carefully pour the egg mixture over the fillings in each cup, filling each one to about three-quarters full to leave room for the eggs to expand slightly as they cook. Sprinkle the reserved cheddar over the top of each cup.

Step 5 - Bake until just set: Place the muffin tin in the center rack of the preheated oven and bake for 20 to 24 minutes. The muffins are done when the centers are fully set and no longer jiggle when you gently shake the pan, and the tops are lightly golden. Do not overbake — the muffins will continue to cook slightly from residual heat after they come out of the oven, and an extra five minutes in the oven will push them past the point of ideal texture into rubbery territory.

Step 6 - Cool before removing: Let the muffins rest in the pan for five full minutes before attempting to remove them. This resting period allows the protein structure to firm up completely and the muffins to pull slightly away from the sides of the cups on their own, which makes releasing them clean and easy. Run a thin knife or offset spatula around the edge of each cup if needed, then lift them out gently. Allow them to cool completely on a rack before storing in an airtight container.
