How to Make a Breakfast Potato Casserole – Step-by-Step Guide

Step 1: Prepare Your Ingredients
If you’re using fresh potatoes, peel and dice or shred them. For quicker preparation, frozen hash browns work perfectly and save time. Cook your choice of breakfast meat until browned and crispy. Chop onions, peppers, or any veggies you plan to add.
Step 2: Mix the Egg Mixture
In a large bowl, whisk together eggs, milk or cream, and seasonings. This mixture will soak into the potatoes and other ingredients to create a custard-like texture when baked.
Step 3: Combine Everything
Add the potatoes, cooked meat, veggies, and half the cheese to the egg mixture. Stir well to evenly distribute all ingredients.
Step 4: Assemble the Casserole
Grease a baking dish (9×13-inch works great). Pour the mixture into the dish and smooth it out. Sprinkle the remaining cheese on top.
Step 5: Bake
Bake in a preheated oven at 350°F (175°C) for about 45-60 minutes. The casserole should be golden brown on top and set in the middle (a knife inserted should come out clean).
Step 6: Serve and Enjoy
Let the casserole cool for a few minutes before cutting into squares. Serve with fresh fruit, toast, or a side of salsa.
Tips for Making the Best Breakfast Potato Casserole

- Use Day-Old Potatoes: For a firmer texture, leftover roasted potatoes work well.
- Don’t Overmix: Stir just enough to combine ingredients without breaking down the potatoes.
- Customize Your Cheese: Sharp cheddar offers bold flavor, but mixing cheeses can add creaminess or spice.
- Add Fresh Herbs: Chopped parsley, chives, or green onions on top brighten the dish.
- Try Different Meats: Substitute sausage with turkey bacon, chorizo, or keep it vegetarian.
