Step‑by‑Step Instructions for Ham and Cheese Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350ºF (175ºC). This ensures that the Ham and Cheese Breakfast Casserole bakes evenly and achieves that golden-brown perfection you’re looking for. As the oven is warming up, gather your ingredients and prepare your baking equipment to streamline the cooking process.
Step 2: Whisk the Egg Mixture
In a large mixing bowl, whisk together 8 large eggs, 1/2 cup of milk, 1 tablespoon of stone ground mustard, and a pinch of salt and pepper. Mix until the ingredients are well combined and frothy, taking about 2–3 minutes. The goal is a smooth mixture that will provide richness to the casserole, perfectly complementing the ham and cheese.
Step 3: Prepare the Casserole Base
In another large bowl, take 2 cans of Grands biscuits that you’ve cut into quarters and add 1/4 lb of chopped deli ham along with half of the 8 ounces of shredded tri cheddar cheese. Toss these ingredients together gently until coated. The biscuit pieces will provide a fluffy base, while the ham contributes savory flavor to your Ham and Cheese Breakfast Casserole.
Step 4: Combine Egg and Biscuit Mixtures
Pour the egg mixture over the biscuit mix, using a spatula to gently fold everything together. This step should take about 1–2 minutes to ensure that the biscuits and ham are well-coated with the egg mixture. You’ll see the biscuits become moist, making them ready to soak up all that deliciousness during baking.
Step 5: Transfer to Casserole Dish
Grease a 9×13-inch casserole dish to prevent sticking, then pour the combined mixture into the dish, spreading it evenly. Cover the dish tightly with aluminum foil to ensure the casserole steams as it bakes, helping the biscuits become tender. Place it in the preheated oven once it’s all set.
Step 6: Bake Covered
Bake the casserole for 30 minutes covered in the foil. This helps everything cook through while retaining moisture. After 30 minutes, carefully remove the foil and sprinkle the remaining shredded cheese on top, allowing it to melt beautifully in the final baking stage.
Step 7: Bake Uncovered
Return the casserole to the oven and bake uncovered for an additional 15 minutes, or until the cheese is golden and bubbly. Keep an eye on it to avoid over-browning. The aroma filling your kitchen will signal that your Ham and Cheese Breakfast Casserole is nearly ready!
Step 8: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for 5-10 minutes. This resting period makes it easier to slice and serve. Top with sliced green onions for garnish and pair with a light sauce, such as honey or hollandaise, to elevate your hearty breakfast that’s sure to impress!

Make Ahead Options
This Ham and Cheese Breakfast Casserole is perfect for busy home cooks looking to save time! You can assemble the entire casserole up to 24 hours in advance by pre-mixing the egg and biscuit components. Simply cover the dish tightly with aluminum foil to prevent drying out and refrigerate. If you prefer, you can also prepare the ingredients (chopping ham and measuring cheese) up to 3 days ahead. When you’re ready to bake, just pop the casserole into the preheated oven, adding an extra 5-10 minutes to the cooking time for a perfect finish. This way, you can impress your family with a delicious breakfast casserole without the morning rush!
