What You’ll Need:
This Cheesy Breakfast Casserole ingredient list is intentionally simple—because good food doesn’t need to be complicated.
- 8 large eggs
- 1 cup milk (whole or 2% works great; swap with unsweetened almond milk if you’re dairy-free)
- 2 cups shredded cheese (I love sharp cheddar, but mozzarella or Monterey Jack work just as well)
- 4 cups cubed bread (day-old or fresh bread both work; use whole-grain for extra fiber)
- 1 cup cooked veggies (spinach, bell peppers, or mushrooms are my favorites)
- ½ tsp salt
- ¼ tsp black pepper
- 1 tsp garlic powder (optional, but adds a nice depth)
- Optional: 1 cup cooked sausage or bacon, chopped (for extra protein and flavor)
No stress if you don’t have all the ingredients—I often use whatever veggies I have sitting in the fridge for this Cheesy Breakfast Casserole. Frozen spinach or peppers are great shortcuts when fresh isn’t around. You can find bread and eggs easily in any regular full-service grocery store, and cheese is usually in the dairy aisle or specialty cheese section.
Budget-friendly note: This Cheesy Breakfast Casserole keeps costs low by relying on staple ingredients many people already have. Plus, if you’re working with leftovers like bread or cheese, it’s a fantastic way to avoid waste.
For busy days, consider chopping your veggies and cubing your bread ahead of time and storing them in the fridge. Leftovers keep well covered in the fridge for up to 3 days—great for reheating quick breakfast bites that still feel fresh.
I personally love adding extra cheese on top before baking—it melts into a golden, bubbly layer that’s hard to resist!
Let’s Make It Together!
Okay, fellow home cook, here’s how we’ll whip up this Cheesy Breakfast Casserole without stress.
- Preheat your oven to 350°F (175°C). Greasing a 9×13-inch baking dish is a good idea to keep things from sticking.
- Prep your bread and veggies. Cube your bread into bite-sized pieces and chop your cooked veggies if needed. I often use pre-cooked veggies to speed things up, but raw bell peppers or mushrooms work if you sauté them lightly first.
- In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder if you’re using it. This forms the lovely custard base for your cheesy breakfast bake.
- Add the bread cubes, cooked veggies, cheese, and meat if using directly into the egg mixture. Stir gently to combine, making sure every piece gets a little bit of that cheesy egg love.
- Pour the entire mixture into your greased baking dish and spread evenly. It’s okay if it looks a bit packed or rustic—that’s part of the charm.
- Pop your Cheesy Breakfast Casserole in the oven for about 40-45 minutes. You’ll know it’s done when the center is set, and the top looks golden and smells wonderful. Your kitchen will be smelling like a cozy Sunday morning in no time!
- While it’s baking, perfect time to set the table or quickly prep a simple side like fresh fruit or yogurt.
- Once baked, let it cool for a few minutes before slicing. This helps keep those delicious layers intact.
Here’s where I used to overcomplicate my Cheesy Breakfast Casserole—turns out simpler is better! This recipe usually takes about an hour start to finish, but the hands-off baking time is perfect for catching up on a favorite podcast or quickly brushing up on a book.
If you want a stress-free morning, try making this ahead of time. An overnight breakfast casserole version lets the bread soak up all the eggy goodness while you sleep. Check out this tasty overnight sausage and egg breakfast casserole for inspiration.
For those wondering, don’t worry if your Cheesy Breakfast Casserole looks a little jiggly when it comes out of the oven. It firms up as it cools—patience is tasty!
How I Love to Serve This!
This Cheesy Breakfast Casserole becomes a complete meal when I add a side of fresh fruit or a crisp green salad—it balances the richness and adds a refreshing touch.
Some weekends, I pair it with simple homemade salsa or avocado slices to add a creamy, zesty punch. It’s also lovely topped with a dollop of sour cream or Greek yogurt for extra tang.
My go-to Cheesy Breakfast Casserole shines best on relaxed weekends or early morning brunches with friends. It’s an all-in-one dish that lets everyone dig in without fuss.
Presentation tip: Serve your casserole straight from the pan for a homey feel or transfer slices to individual plates with a sprinkle of fresh herbs like parsley or chives. This little touch makes it feel extra special.
Leftovers? No problem! I slice up what’s left and enjoy them cold or reheat small portions in the microwave—still cozy and comforting. For a twist, try folding leftover pieces into a breakfast wrap or sandwich.
Seasonally, I swap in whatever vegetables the farmers’ market is offering. Spring asparagus or summer zucchini bring new life to this baked breakfast dish.
