How to nail the perfect egg texture
For a silky Sausage & Egg Breakfast Casserole Mug, whisk the egg and liquid thoroughly to aerate and avoid dense pockets. Distribute sausage and veggies evenly so your microwave breakfast cooks uniformly. Microwave only until the center barely jiggles, then rest one minute—carryover heat sets the casserole in a mug gently.

These tiny choices add up to a luscious, high-protein egg mug with diner-level coziness in minutes.
