Tips for Best Results
- Don’t skip the 10-minute resting time before you slice into it.
- Avoid overcooking the eggs or the edges might become too dry.
- Swap the pork sausage for turkey sausage for a leaner protein option.
- Brown the sausage and chop the veggies the night before to save time.
- Add a handful of fresh spinach for an extra boost of winter greens.
- Use a high-quality parmesan cheese for the most savory flavor profile.
Ways to Switch It Up

- Swap red peppers for sun-dried tomatoes for a deeper Italian flavor.
- Add a pinch of red pepper flakes if you enjoy spicy food.
Common Questions
Can I make this ahead of time?
Yes, you can assemble the entire dish the night before. Cover it tightly and keep it in the fridge until morning. Just add five minutes to the bake time if it is cold.
How do I know when the eggs are done?
The center should be firm and not jiggle when you move the pan. The top will be puffed and golden brown. A knife inserted in the middle should come out clean.
Will kids like this recipe?
Most kids love the mild flavor of mozzarella and savory sausage. You can dice the vegetables very small so they blend right in. It is a picky-eater friendly way to serve eggs.
I hope this cozy breakfast brings your family together this winter. It is such a simple way to make any morning feel special. Happy cooking!
