Key Ingredients for a Loaded Casserole
Crafting the perfect Cheesy Breakfast Casserole starts with quality ingredients that build layers of flavor and texture. Here’s what you’ll need:
- Breakfast Meats: We love crispy bacon and savory breakfast sausage (1 lb each). Cook and crumble well, then drain all grease thoroughly to prevent a greasy or soggy breakfast casserole. Try turkey sausage or diced ham for variations, creating a delicious sausage breakfast casserole or breakfast casserole with bacon.
- Potatoes: A 20-ounce bag of frozen potatoes with peppers and onions adds flavor and convenience. Alternatives include shredded hash browns, tater tots, or par-cooked fresh diced potatoes for your breakfast casserole with hashbrowns.
- Eggs: 10-12 large eggs are essential for binding and creating a fluffy, rich texture in this egg and cheese casserole.
- Milk: Whole milk provides the best richness for a creamy custard. 2% milk or half-and-half are suitable alternatives for this potato and egg casserole bake.
- Cheese: Sharp cheddar is the classic choice for the best cheese for breakfast casserole. For superior melting, shred your own from a block. Colby Jack, Monterey Jack, or Pepper Jack are also great.
- Seasonings: Kosher salt, fresh ground black pepper, and garlic powder are vital for elevating the flavors of the eggs and overall dish.
Step-by-Step Instructions to a Perfect Casserole
Making this incredible Cheesy Breakfast Casserole is surprisingly simple. Follow these steps for a dish that will impress every time:
- Prepare the Meats: Cook bacon until crispy, crumble, and set aside. Cook sausage breakfast casserole meat until browned and crumbled. Drain all excess grease thoroughly from both meats to avoid a greasy casserole.
- Layer the Base: Lightly grease a 9×13 inch baking dish. Spread the frozen potato mixture (with peppers and onions) evenly. Sprinkle cooked bacon, sausage, and half of the shredded cheese over the potatoes. This is key for a well-distributed casserole with peppers and onions.
- Mix the Egg Custard: In a large bowl, whisk eggs, milk, salt, pepper, and garlic powder until smooth. This liquid gold is the « glue » for your delicious simple egg bake.
- Assemble the Casserole: Pour the egg mixture evenly over the layered ingredients in the baking dish.
- Top and Bake: Sprinkle the remaining cheese generously on top. Bake in a preheated 350°F (175°C) oven for 45-55 minutes, until golden brown, puffed, and a knife inserted into the center comes out clean.
- Rest and Serve: Crucially, let the casserole rest for 5-10 minutes after baking. This allows the eggs to set, ensuring clean, beautiful slices of your holiday breakfast casserole.
Pro Tips for Casserole Success
Achieving breakfast casserole perfection is easy with these expert tips:
- Avoid a Soggy Bottom: Drain all meat grease completely. If using frozen potatoes, pat them dry of excess ice crystals. This minimizes moisture for a perfect potato and egg casserole bake and prevents a soggy breakfast casserole.
- Shred Your Own Cheese: Freshly grated cheese melts much smoother and gooier than pre-shredded varieties, which contain anti-caking agents. For the best Cheesy Breakfast Casserole, shred a block!
- Don’t Overbake: Overbaking yields dry, rubbery eggs. Watch for golden brown edges and a firm center. The internal temperature should be 160-165°F (71-74°C).
- Room Temperature Ingredients: Let eggs and milk sit out for 20-30 minutes. This helps the custard cook more evenly and prevents curdling.
- Check for Doneness: Use the ‘knife test’ (insert near center, comes out clean) or an instant-read thermometer for guaranteed perfect results every time.
Fun Variations & Customizations
The versatility of this Cheesy Breakfast Casserole is endless. Make it your own with these creative ideas:
- Add More Veggies: Sauté mushrooms, spinach (squeezed dry), bell peppers, or jalapeños before adding them to the layers. Creates a vibrant, even more loaded breakfast bake.
- Swap the Meats: Use diced ham (great for leftovers!), Canadian bacon, or spicy chorizo. Make it a dedicated sausage breakfast casserole or breakfast casserole with bacon.
- Change the Cheeses: Experiment with Swiss and Gruyère for a nutty flavor, or Pepper Jack for a spicy kick. A Mexican blend also works wonderfully for a southern breakfast casserole vibe.
- Make it Vegetarian: Omit meat and load up on sautéed vegetables like onions, mushrooms, bell peppers, and spinach. Plant-based sausage crumbles can also be added for a satisfying breakfast casserole without bread.
- For a Low-Carb/Keto Version: Replace potatoes with steamed cauliflower florets or omit them, increasing meat, cheese, and low-carb veggies for a delicious keto egg and cheese casserole.
Make-Ahead, Storage, and Reheating Guide

How to Make it an Overnight Casserole

How to Freeze Breakfast Casserole
Yes, you can you freeze breakfast casserole! Allow the baked casserole to cool completely. Freeze the entire casserole or individual portions wrapped tightly in plastic then foil for up to 3 months. Thaw in the refrigerator before reheating.
The Best Way to Reheat
Reheat individual slices in the microwave (1-2 minutes) or oven. For a whole casserole, cover with foil and reheat in a 300°F (150°C) oven until warmed through.
What to Serve with Your Cheesy Breakfast Casserole
While this Cheesy Breakfast Casserole is a complete meal, a few simple sides can perfectly complement its richness:
- A refreshing fresh fruit salad adds bright, contrasting flavors.

Frequently Asked Questions (FAQ)
How do I keep my breakfast casserole from getting soggy?
To prevent a soggy breakfast casserole, ensure you thoroughly drain all grease from cooked meats. If using watery vegetables (like spinach), sauté them first to release moisture. Using pre-cooked or frozen potatoes also helps, especially when making a potato and egg casserole bake.
Can I use bread instead of potatoes in this recipe?
Absolutely! Substitute potatoes with 6-8 cups of cubed day-old bread (sourdough, challah, or French bread) to create a breakfast strata. Arrange bread cubes before adding other layers and the egg mixture. This is an excellent breakfast casserole without bread option.
Do I need to thaw frozen potatoes before using them?
No, you do not need to thaw frozen potatoes. They can go directly into the baking dish from the freezer, which is a fantastic time-saver. Just break up any large clumps of breakfast casserole with hashbrowns.
Can I make this cheesy breakfast casserole in a slow cooker?
Yes! Brown meats first, then layer all ingredients in a greased slow cooker. Pour the egg mixture over everything. Cook on low for 4-6 hours or on high for 2-3 hours until eggs are set and a knife comes out clean. Perfect for a breakfast casserole for a crowd.
What’s the best way to tell when an egg casserole is done?
The casserole is done when it’s golden brown and puffed, with a firm center that doesn’t jiggle. Insert a thin knife near the center; if it comes out clean, it’s ready. An instant-read thermometer should read 160-165°F (71-74°C) for your egg and cheese casserole.
