There’s something truly comforting about waking up to the aroma of a warm Cheesy Breakfast Casserole baking in the oven. I remember the first time I made this delicious breakfast bake—it was one of those busy weekend mornings where I needed something hearty but hands-off. The smell of melted cheese mingling with eggs and savory sausage was like a cozy hug for my whole family. From that moment, this cheese breakfast casserole became our go-to morning treat for holidays, sleepovers, or simply when life was a little too hectic for anything fancy.
What You’ll Need for This Cheesy Breakfast Casserole

Alright girlfriend, here’s a quick rundown of what you’ll want to gather before we dive into this cheesy breakfast casserole magic. I’m always sure to use quality sharp cheddar for a bold flavor, but sometimes I mix in mozzarella for that extra melty stretch. Also, for my easy breakfast casserole, I like to stick to simple ingredients—you know, things you might already have stocked.
- 1 pound breakfast sausage (I always go for the mild, but spicy works if you like a kick!)
- 6 large eggs (room temperature is best for fluffy texture)
- 1 cup whole milk (half-and-half works too if you want it richer)
- 3 cups shredded sharp cheddar cheese
- 4 cups bread cubes (day-old or lightly toasted bread holds up better)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon garlic powder (a little goes a long way for depth)
- Optional: 1 cup diced bell peppers or spinach (secret veggie boost for the kids!)
When making this cheesy breakfast casserole, try to find your bread from the bakery section for the freshest taste—you can also use a good-quality sandwich loaf. I’ve learned the trick of toasting bread cubes lightly beforehand to avoid sogginess in the final casserole. For the sausage, I buy in bulk from the meat department and freeze in portions—perfect for multiple casserole breakfasts without breaking the bank.
If you ever have leftovers from your cheese breakfast casserole fixings, like extra shredded cheese or eggs, I keep them in airtight containers in the fridge. It’s such a great way to cut down on food waste and have ready ingredients for a fast egg and cheese casserole next week. For more tips on how to prep ingredients efficiently, I love this guide on Cheesy Overnight Hash Brown Egg Casserole from The Food Charlatan, which also gives terrific ideas for ingredient variations.
Let’s Make This Cheesy Breakfast Casserole Together
Ready to get your hands a little messy and make this cheesy breakfast casserole come alive? I’ll walk you through each step just like I do in my kitchen, where this breakfast bake usually takes me about 45 minutes from start to finish.
- Brown the Sausage – Grab a skillet and cook your breakfast sausage over medium heat until nicely browned and cooked through. Drain any excess fat. I learned the hard way that skipping this step makes the casserole greasy and less flavorful, so take your time here. While the sausage is cooking, preheat your oven to 350°F (175°C).
- Prepare the Bread Cubes – If you didn’t toast your bread cubes ahead of time, you can spread them on a baking sheet and toast in the oven for about 10 minutes just until slightly golden. This little breakfast casserole trick helps soak up the egg mixture better without turning mushy.
- Mix the Eggs and Milk – In a large bowl, whisk together your eggs, milk, salt, pepper, and garlic powder. Don’t worry if your mixture looks thin; it will puff up as it bakes, creating that fluffy texture we love.
- Assemble the Casserole – Combine the browned sausage, toasted bread cubes, and optional veggies if you’re using. Pour them into a greased 9×13 baking dish. Sprinkle about two cups of that shredded cheddar evenly over the top, saving the rest for a melty finish later.
- Add the Egg Mixture – Slowly pour the egg mixture over everything, making sure to coat all bread pieces. This step is where your casserole starts coming together. Trust me, if you let it sit for just a minute or two, the bread will soak up the custard wonderfully.
- Bake – Cover the casserole with foil and bake for 35 minutes. Then, remove the foil and sprinkle the remaining cheese on top. Bake uncovered for another 10 minutes or until the cheese is bubbling and golden brown. Your cheesy breakfast casserole should smell heavenly by now—that’s a sure sign it’s ready!
I usually multitask while the casserole is baking—tidying up the kitchen or setting the table. And if you ever want to make this ahead, it works beautifully as an overnight breakfast casserole; just refrigerate it covered after assembling and bake when you wake up.

How I Love to Serve This Cheesy Breakfast Casserole
Serving up this cheesy breakfast casserole is one of my favorite parts of the day because it brings everyone together around the table. My family always loves this dish best with a side of fresh fruit—something like sliced oranges or berries really brightens up the rich flavors of the casserole.
I also often pair it with crispy bacon or a fresh green salad when I want to add a little crunch and freshness.

If you find yourself with leftovers, don’t panic! Leftover cheesy breakfast casserole packs perfectly for weekday breakfasts or even lunch. Reheat it in the oven or microwave, and it tastes just as good the next day. A fun twist I tried recently was adding a dollop of sour cream or salsa on top for some extra flavor.
