Step‑by‑Step Instructions for Ham and Cheese Breakfast Casserole

Step 1: Prepare Egg Mixture
In a large mixing bowl, whisk together 12 large eggs, 2 cups of 2% milk, and season with salt and pepper to taste. Continue whisking until the mixture is smooth and well combined, creating a rich and creamy base for your Ham and Cheese Breakfast Casserole. Set aside while you layer the other ingredients.

Step 2: Layer Ingredients
Grease the slow cooker insert generously to prevent sticking, then begin layering your casserole. Start with one-third of the 30 oz. of thawed, shredded hash brown potatoes, followed by one-third of the 2 cups of cubed fully cooked ham, a third of your chopped onion, and a third of the 4 cups of shredded cheddar cheese. Repeat this layering process two more times, finishing with a layer of cheese at the top.

Step 3: Combine Ingredients
With the layers complete, pour the prepared egg mixture evenly over the layered ingredients in the slow cooker. Gently press down on the layers with a spatula to ensure the egg mixture seeps throughout the Ham and Cheese Breakfast Casserole, coating all components and enhancing the flavors.

Step 4: Chill
Cover the slow cooker insert with plastic wrap and place it in the refrigerator overnight. Letting the casserole sit overnight allows the flavors to meld beautifully, creating a savory dish that is bursting with flavor when you wake up to cook.

Step 5: Cook
On the day you’re ready to serve, remove the insert from the refrigerator and place it into the prepped slow cooker. Cover and cook on low for 4 to 5 hours. You’ll know the casserole is done when the edges are set and lightly browned, and the center has a slight jiggle but is cooked through.

Step 6: Rest & Serve
Once your Ham and Cheese Breakfast Casserole is ready, turn off the slow cooker and let it rest uncovered for about 30 minutes. This resting period helps set the casserole and improves its texture. Serve it warm, cut into squares, and enjoy the delightful layers of flavor with your favorite breakfast sides!

What should I do if my casserole is too soggy?
If your casserole comes out too soggy, it might be due to excess moisture from undrained hash browns or eggs. To avoid this, make sure your hash browns are fully thawed and drained. You can also let the casserole rest longer after cooking, which helps firm up the texture.

Is this casserole pet-friendly?

Certainly! For dairy allergies, substitute the milk with a non-dairy alternative like almond or oat milk, and use a dairy-free cheese option. For egg allergies, a mix of silken tofu and nutritional yeast can sometimes replace eggs; however, this might alter the texture and flavor. Always check for other specific allergens in the ingredients used!
