Step-by-Step Instructions

- In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until smooth.
- Mix in the sautéed veggies, diced potatoes (or hash browns), shredded cheese, and cooked sausage or bacon. If using spinach or mushrooms, add them now and stir until combined.

- Bake for 30–35 minutes or until the eggs are set and the top is golden brown.
- Allow to cool slightly before slicing and serving.
How to Serve Potato Breakfast Casserole
For an appetizing presentation, slice the casserole into squares and serve it warm. Pair it with a light green salad for a refreshing contrast or some homemade salsa for a tangy kick. Want to elevate your brunch? Serve alongside mimosas or freshly brewed coffee. Each bite will pair wonderfully with a sip of your favorite morning beverage, making breakfast feel like a special occasion.
Keeping Leftovers Fresh
Storing leftovers is a breeze with this casserole! Place any uneaten portions in an airtight container in the fridge. It will keep well for up to 4 days. For longer storage, consider freezing individual slices. When you’re ready for a quick meal, simply reheat in the oven or microwave until warmed through.
Helpful Cooking Tips
- Ensure your eggs are well-whisked for a fluffy texture throughout the casserole.
- Don’t overcrowd the baking dish; a sufficiently spaced casserole allows even cooking and browning.
- Feel free to experiment with different cheeses—think pepper jack for a spicy twist or feta for a Mediterranean flair.
Creative Twists
Want to switch things up? Here are some fun variations to consider:
- Swap out the bell pepper for diced zucchini or squash for a garden-fresh feel.
- Add herbs like rosemary or thyme for an aromatic boost.
- Try using sweet potatoes instead of regular potatoes for a subtly sweet flavor.
