Preheat your oven to 325°F. Generously spray a nonstick or silicone muffin pan with cooking spray. (I used a silicone pan. So easy to clean and the egg bites pop right out.)
You can cook the bacon on the stovetop or in the microwave:Skillet method: In a small pan over medium-high heat, cook the diced bacon, stirring occasionally, until crispy (about 5–6 minutes). Drain on a paper towel.Microwave method: Place bacon pieces between two paper towels on a microwave-safe plate. Microwave on high for 3–4 minutes, checking at 30-second intervals until crispy. In a large bowl, whisk together the eggs, cottage cheese, Gruyère, cornstarch, salt and pepper, until smooth and well combined. Stir in the cooked bacon.
Divide the mixture evenly among the muffin cups, filling each about ¾ full.
Bake on the middle rack for 20–25 minutes, or until the egg bites are set and just beginning to pull away from the sides.
Let rest in the pan for 5 minutes before removing.
