How to Make It

This casserole comes together with just a few straightforward steps.

Prepare the oven

Preheat the oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish to prevent sticking.

Cook the fillings

Cook bacon in a skillet until crispy, then chop it into smaller pieces. If using raw onion or bell pepper, sauté them for 3–4 minutes to soften and bring out their flavors.

Mix the egg base

In a large bowl, whisk together the eggs, milk, cream (if using), salt, and pepper until well combined to create a smooth egg mixture.

Assemble the casserole

Spread the diced potatoes evenly in the prepared baking dish. Add the chopped bacon, sautéed onion, bell pepper, and half of the cheddar and mozzarella cheeses. Pour the egg mixture evenly over the top. Finally, sprinkle the remaining cheese on top for a golden finish.

Bake

Bake uncovered for 35–40 minutes, or until the center is set and the top is lightly golden brown for that appealing look.

Rest and serve

Let the casserole rest for 5–10 minutes before slicing and serving. You can garnish with chopped green onions if desired for a fresh touch.

How to Store It

Fridge: Store in an airtight container for up to 3 days.
Freezer: Yes, freezes well for up to 2 months.
Reheat: Microwave or bake at 350°F (175°C) for 15–20 minutes.

Tips for Best Results
