02 / HOW TO MAKE IT

Let's cook.

01

Brown and crumble sausage

Start by heating a large skillet over medium-high heat. Cook the sausage, breaking it up as it browns and becomes crumbly, which should take about 5 to 7 minutes. Once done, take it off the heat and let it cool for a few minutes before transferring it to a big mixing bowl.

Combine and Layer Ingredients

Add the hash browns, ham, Monterey Jack cheese, dry mustard, and onion powder to the sausage, then give everything a good stir to combine. Spread this mixture loosely into a greased 9x13-inch baking dish. In a separate bowl, whisk together the eggs, evaporated milk, half-and-half, salt, and pepper until smooth. Pour this mixture evenly over the hash browns and sausage. Cover the dish with foil and pop it in the fridge for at least 8 hours or overnight.

Bake and Melt Cheese

When you’re ready to bake, take the casserole out of the fridge about 30 minutes beforehand so it can come closer to room temperature. Sprinkle the Cheddar cheese on top and cover it again. Preheat your oven to 350°F (175°C). Bake the casserole for 45 minutes, then remove the foil and cook for another 15 to 20 minutes until the cheese is melted and bubbly. Let it sit for about 10 minutes before serving so it sets up nicely.

Good to know.

Cook's tip

- Use day-old bread to help soak up the custard without becoming too soggy.
- Let the casserole rest for 10 minutes after baking to make slicing easier.
- Cover tightly with foil when baking to prevent the top from browning too quickly.

Why you’ll love it

This dish is perfect for busy mornings because it can be prepared the night before. It combines eggs, cheese, and bread for a comforting and filling start to the day. Plus, it can easily be customized with your favorite vegetables or meats.

Serving ideas

Serve warm with a side of fresh fruit or a simple green salad to balance the richness. A dollop of sour cream or a drizzle of hot sauce can add extra flavor. This casserole pairs well with a cup of coffee or fresh squeezed juice.

Storage & leftovers

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or oven until warmed through. You can also freeze slices wrapped tightly in plastic wrap and foil for up to 2 months.
