Ingredients for Cozy Breakfast Casserole
- 1 pound breakfast sausage (or substitute with beef bacon, turkey bacon, or chicken strips)
- 6 green onions, chopped (reserve some tops for garnish)
- 1 red bell pepper, chopped
- 10 large eggs
- 1 1/4 cups heavy cream (or you can use whole milk for a lighter option)
- 1 tablespoon Dijon mustard
- 2 teaspoons Tabasco sauce (optional for those who enjoy a little heat)
- 1 1/2 teaspoons salt
- 1 teaspoon black pepper
- 3 cups sharp cheddar cheese, shredded
- 1 (30 ounce) package frozen shredded hash browns, thawed
Ingredient Notes
When sourcing your ingredients, feel free to mix and match based on what you have on hand or dietary preferences. For the sausage, you can easily opt for a non-pork variant that fits your family’s needs, and the heavy cream can be switched out for lighter alternatives without compromising on creaminess.

How to Make It
Step 1 – Preheat the Oven and Prepare Your Baking Dish
To kick things off, preheat your oven to 350°F (175°C). While the oven is warming up, take a 9-by-13-inch baking dish and generously spray it with nonstick spray. This will ensure that your delicious casserole slides right out once it’s time to serve—no one wants a sticky situation!
Step 2 – Cook the Sausage Mixture
Heat a large skillet over medium-high heat and add in your breakfast sausage (or whichever meat substitute you’ve chosen). Toss in the chopped red bell pepper along with the white and light green segments of the green onions. As the sausage cooks, use a wooden spoon to crumble it into smaller pieces. It should take about 6 to 8 minutes for the sausage to turn golden brown and the vegetables to become tender. Once they’re done, remove the skillet from the heat and let the mixture cool slightly while you prepare the next components.
Step 3 – Whisk the Egg Mixture
In a large mixing bowl, crack open your 10 eggs like you’re unleashing a little sunshine. Add the heavy cream, Dijon mustard, a few dashes of Tabasco (if you’re feeling adventurous), salt, and black pepper. Grab a whisk and blend everything together until it’s smooth and just begging to be poured into your casserole dish. This mixture is what will hold everything together, bringing a creamy dreamy texture to each bite.
Tips for Success
- Make it your own: Add in your favorite veggies or cheeses to the mix—spinach, mushrooms, or even crumbled feta can take this dish to new heights!
- Make it ahead: This casserole can be assembled the night before; just pop it in the fridge and bake it in the morning. Perfect for those busy mornings!
- Check for doneness: Baking times may vary based on your oven; just ensure the center is set and slightly jiggly when you take it out.
Recipe Variations
- Mediterranean Casserole: Add chopped spinach, kalamata olives, and feta cheese for a Mediterranean twist.
- Tex-Mex Casserole: Switch in chorizo for the sausage and add some diced tomatoes and jalapeños. Top with avocado and cilantro before serving.
- Garden Veggie Casserole: Mix in zucchini, bell pepper, and fresh herbs of your choice for a garden-fresh flavor.
- Sweet Potato Delight: Replace hash browns with shredded sweet potatoes for a delicious sweet and savory combination.
- Cheesy Broccoli Casserole: Stir in steamed broccoli to boost the nutritional value and add some vibrant color.
Serving Ideas
This Cozy Breakfast Casserole is perfect on its own, but I love to serve it with a side of fresh fruit or a vibrant green salad to brighten the plate. Pour a little hot sauce on top for those who like extra kick, or drape it with a dollop of sour cream. You can also pair it with freshly baked biscuits or crusty bread to soak up all that deliciousness.

Storage and Freezing
If you have leftovers (which can be rare with this dish), don’t fret! The casserole will keep well in the refrigerator for up to 3 days. Just cover it tightly with foil or transfer it to an airtight container. You can also freeze it before baking. Just assemble everything in your baking dish, freeze it before cooking, and then you can bake it straight from the freezer when you’re ready, adding an additional 15–20 minutes to the cooking time. It’s a lifesaver for those busy mornings when you want something homemade but don’t have time to cook.

FAQ About Cozy Breakfast Casserole
Can I use fresh hash browns instead of frozen?
Absolutely! If you have freshly grated potatoes, you can use those instead. Just be sure to squeeze out excess moisture before mixing in.
How can I make this casserole vegetarian?
Omit the meat, and add in your favorite sautéed veggies. Plant-based sausage options can also provide that savory flavor without the meat.
Can I use egg substitutes?
Yes! If you prefer to avoid eggs, you can try using a commercial egg substitute or a flaxseed meal mixed with water as a binder.
How do I know when my casserole is done baking?
The casserole should be puffed up and look set in the center. A knife inserted into the center should come out clean, and the edges should be golden.
Is this casserole good for meal prep?
Definitely! You can prepare it ahead of time, refrigerate it overnight, and bake it fresh in the morning. This allows flavors to marry beautifully, making it even more delicious.
