When I first made this Baked Breakfast Potato Casserole, I wasn’t sure how it would turn out, but the result was phenomenal! The combination of crispy potatoes, fluffy eggs, and melted cheese created an irresistible dish that my family couldn't get enough of. I also experimented with adding different herbs and spices, which elevated the flavors to a whole new level.

One of the tips I've found is to par-cook the potatoes before layering them in the casserole. This ensures they are soft on the inside and get perfectly crispy on the outside while baking. You can also prepare this dish the night before; just bake it in the morning for a quick and hearty breakfast!

The Perfect Potato Choice

When it comes to selecting potatoes for this casserole, I recommend using starchy varieties like Russets or Yukon Golds. These types create a fluffy texture once baked, allowing them to absorb the flavors of the eggs and seasonings beautifully. Avoid waxy potatoes, such as red potatoes, as they can become mushy and fail to hold their shape in the casserole. For optimal results, make sure to dice the potatoes evenly to ensure consistent cooking throughout.

Par-cooking the potatoes is essential. This step helps reduce baking time and ensures that the potatoes are tender without becoming mushy. Boiling them just until they are barely tender allows them to finish cooking in the oven while absorbing the flavors of the egg mixture. As a tip, you can test their doneness by piercing a piece with a fork; it should slide in easily but not break apart.

Egg Mixture Essentials

The egg mixture is the heart of this casserole, providing structure and creaminess. Whisking the eggs with milk not only increases the volume but also adds a rich flavor. I like to use whole milk for a creamier texture, but you can substitute with almond milk or any non-dairy milk for a lighter or lactose-free option. Just be sure to choose one that’s unsweetened to keep the savory profile of the dish intact.

Don’t skip the seasoning! The addition of garlic powder and paprika introduces layers of flavor that elevate the entire dish. If you're looking for a bit of heat, consider adding a pinch of cayenne or red pepper flakes to the mixture. Alternatively, fresh herbs like chopped parsley or chives can add freshness, making each bite taste even more delightful.

Instructions

Follow these easy steps to make your Baked Breakfast Potato Casserole.

Preheat the Oven

Preheat your oven to 375°F (190°C).

Par-Cook the Potatoes

In a large pot, boil the diced potatoes for about 10 minutes until just tender. Drain and set aside.

Sauté Vegetables

In a skillet, heat olive oil over medium heat and sauté the bell pepper and onion until soft, about 5 minutes.

Prepare the Egg Mixture

In a bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and paprika.

Assemble the Casserole

In a large baking dish, layer the par-cooked potatoes, sautéed vegetables, and half of the cheese. Pour the egg mixture over the top and sprinkle with the remaining cheese.

Cover the dish with foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the eggs are set and the cheese is bubbly.

Pro Tips

Feel free to add cooked sausage, bacon, or spinach to the casserole for added flavor and nutrition! You can also experiment with different cheeses to suit your taste.

Make-Ahead and Storage

This Baked Breakfast Potato Casserole is an excellent option for meal prep. You can prepare it a day in advance by assembling the casserole without baking it. Once it's layered in the baking dish, cover it with foil and refrigerate. When you're ready to serve, simply increase the baking time by about 10-15 minutes, checking for that golden, bubbly finish as the eggs set.

If you have leftovers, you can store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply place individual portions in the microwave for a minute or two, or for larger servings, pop it back in the oven covered with foil at 350°F for about 15-20 minutes until warmed through.

Serving Suggestions

I love serving this casserole with fresh fruit or a side of avocado slices for a balanced meal. A dollop of sour cream, salsa, or even hot sauce can provide an extra kick, making every serving exciting and unique. Consider pairing it with a simple green salad for a brunch gathering; the freshness of the greens contrasts nicely with the rich casserole.

For an extra touch of indulgence, try adding cooked bacon or crumbled sausage to the layers before baking. You can also switch up the cheese; swapping out cheddar for feta or pepper jack can create a new flavor profile to match your mood. With so many ways to personalize it, this casserole is sure to become a regular in your breakfast rotation.
