1-First Step: Start by preheating your oven to 350°F (175°C). This step ensures even cooking and helps the casserole develop a golden crust. Take a moment to gather all ingredients, known as mise en place, to make the process smooth for a vegan swap, prepare flax eggs ahead if needed.

2-Second Step: In a large bowl, combine 24 oz. frozen hash browns, 16 oz. cubed ham, and 8 oz. shredded sharp cheddar cheese; toss until well mixed. This mixing step, which takes about 2 minutes, builds the base layer and incorporates flavors evenly. For gluten-free adaptations, confirm your hash browns are suitable before proceeding.

3-Third Step: Transfer the mixture to a 9×13-inch baking dish coated with cooking spray. Spread it out evenly for consistent baking. This layering helps achieve the right texture, and if you’re opting for low-calorie versions, use a light spray to reduce fat content.

4-Fourth Step: In the same bowl, whisk 12 large eggs, 1 cup milk, 1 teaspoon salt, and 1/2 teaspoon ground black pepper until fully combined. This takes roughly 1 minute and creates the liquid base that binds everything. For dietary tweaks, like vegan substitutes, whisk in flax eggs here to maintain the ham breakfast casserole’s structure.

5-Fifth Step: Pour the egg mixture evenly over the hash brown mixture in the baking dish. Gently press down with a spoon to ensure all ingredients are submerged, which promotes even cooking. Allow about 1 minute for this, and note that for low-fat options, using skim milk keeps it light.

6-Final Step: Bake uncovered for 1 hour, or until the center is set and edges are golden brown; check at 50 minutes for doneness, as baking time may extend to 1 hour 20 minutes if needed. Let the casserole rest for 5-10 minutes after baking to set properly before serving it makes 12 portions and reheats well. Adaptations like adding more herbs can enhance flavor without changing the core easy ham breakfast casserole process.
