Why Breakfast Sausage Casserole Is a Game-Changer
Let’s be honest, most of us don’t have time to cook an elaborate breakfast every morning. That’s why Sausage Cheese Breakfast Casserole is a lifesaver. It’s:
- Ridiculously easy to make (if you can crack an egg, you can do this).
- Make-ahead friendly (which means more sleep for you).
- Perfect for feeding a crowd (because nobody likes cooking pancakes one by one).
- Customizable (picky eaters? No problem. Add what you love, skip what you don’t).
Plus, it just tastes amazing—like a warm, cheesy hug in casserole form.
The Ingredients: Simple & Delicious
To make Egg Quiche Recipes Breakfast Casserole, you don’t need anything fancy. Just the breakfast essentials:
- Sausage – Go for classic breakfast sausage or spice it up with chorizo.
- Eggs – The glue that holds this masterpiece together.
- Cheese – Because breakfast without cheese is just wrong. Cheddar, mozzarella, or pepper jack all work.
- Milk & Sour Cream – Makes it extra fluffy and creamy.
- Bell Peppers & Onions – Adds a little color and crunch.
- Salt, Pepper, & Garlic Powder – Because seasoning is everything.
Got leftovers in the fridge? Throw ‘em in. Mushrooms, spinach, diced potatoes—this casserole welcomes all ingredients with open arms.
How to Make Breakfast Sausage Casserole
Step 1: Cook the Sausage
Start by cooking your sausage in a large skillet over medium heat. Break it into crumbles as it browns, and don’t forget to drain the grease—unless you enjoy your casserole swimming in oil.
Step 2: Sauté the Veggies
Toss the chopped bell peppers and onions into the same pan. Let them cook for a few minutes until they soften and smell amazing.
Step 3: Whisk Up the Eggs
Crack your eggs into a big bowl, add the milk and sour cream, and whisk until combined. This is your chance to work on that arm strength you’ve been neglecting.
Step 4: Assemble the Casserole
Grease a 9×13-inch baking dish and layer in the sausage, veggies, and a generous handful of cheese. Pour the egg mixture over everything, letting it fill in the gaps. Sprinkle more cheese on top—because, obviously, more cheese = better.
Step 5: Bake to Perfection
Pop it into a 375°F oven for 35-45 minutes. You’ll know it’s ready when the edges are golden, the center is set, and your kitchen smells like pure breakfast heaven.

- Make-Ahead Option: Assemble everything the night before, cover it, and stash it in the fridge. Bake it fresh in the morning while you enjoy your coffee.

Tips for the Best Breakfast Sausage Casserole
- Use fresh cheese, not pre-shredded – Those bagged shreds don’t melt as well because of anti-caking agents.
- Don’t overbake – Dry eggs are nobody’s friend. Take it out when the center still has a slight jiggle.
- Let it rest before slicing – This makes cutting and serving way easier.
What to Serve with Breakfast Sausage Casserole
This dish is almost a full meal on its own, but if you want to round it out, try these:
- A side of crispy bacon – Because more meat is always a good idea.
- Fresh fruit – To balance out all the cheesy, sausagey goodness.
- Hashbrowns or toast – For a little extra crunch.

Common Questions About Breakfast Sausage Casserole
Can I use bacon instead of sausage?
Absolutely. Or ham. Or chorizo. This casserole is an equal-opportunity breakfast dish.
How do I make it vegetarian?
Skip the sausage and load it up with mushrooms, spinach, and more cheese.
Can I add potatoes?
Yes! Either diced hashbrowns or shredded potatoes will work great.
Why is my casserole watery?
Probably excess moisture from veggies. Try sautéing them first to remove extra liquid.
Can I make this dairy-free?
Yep! Use almond milk and skip the cheese, or swap in a dairy-free alternative.
