Ingredients
- 1 lb (450g) breakfast sausage (pork or turkey)
- 6 large eggs
- 1 cup whole milk (or half-and-half)
- 1 tsp Dijon mustard
- 2 cups shredded sharp cheddar
- 1 can (16 oz) refrigerated flaky biscuits, cut into quarters
- 1/2 tsp salt
- 1/4 tsp freshly ground black pepper
- Optional: 1 cup diced bell peppers or spinach (for a Healthy Breakfast Casserole)
- Nonstick cooking spray or butter (for greasing)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with spray or butter.
- In a skillet over medium heat, cook the sausage until browned, breaking it into crumbles as you stir. Scoop it onto a paper towel to drain excess fat.
- In a large bowl, whisk together eggs, milk, Dijon mustard, salt, and pepper. This blend adds flavor and keeps the bake extra creamy.
- Add the biscuit pieces and half the cheese to the egg mixture. Stir until every bit soaks up some eggy goodness—this creates those fluffy pockets everyone raves about in Breakfast Casserole Recipes.
- Fold in the cooked sausage (and veggies, if using). Pour the mixture into your prepared dish, spreading it evenly.
- Sprinkle the remaining cheddar on top. Feel free to jazz it up with chopped green onions or a light dusting of smoked paprika.
- Bake for 30–35 minutes, or until the casserole puffs up and the center sets. A knife inserted should come out mostly clean.
- Let it rest for 5 minutes before slicing. This pause helps each piece hold its shape—no crumbly mess on your serving platter!
Variations
Spice things up by mixing and matching ingredients. Here are my top three twists that have earned rave reviews at every Brunch Potluck I attend:
Veggie DelightSwap sausage for crumbled tofu or turkey sausage. Add sautéed mushrooms, spinach, and cherry tomatoes for a Healthy Breakfast Casserole that still feels indulgent.
Hashbrown UpgradeReplace biscuits with 3 cups of frozen hashbrowns (thawed) to create an Overnight Breakfast Casserole With Hashbrowns. Layer half the spuds, pour the egg mix, then top with remaining potatoes and cheese.
Tater Tot TwistCrank up the comfort-game by pressing a layer of tater tots on top during the last 15 minutes of baking—hello, Easy Tater Tot Casserole vibes!
Serving & Tips
Serving Ideas
Slice your bake into squares and plate alongside a Breakfast Basket of fresh fruit, yogurt parfaits, or a light mixed green salad. For a fun brunch spread, offer mini quiches and Mini Quiche Recipes with different fillings—your guests will appreciate the variety.
Storage Tips
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave for about 1 minute, or pop them in a 350°F oven for 10 minutes to bring back that just-baked crispness.
Make Ahead & Freezing
Turn this into a Breakfast Casserole Make Ahead hero by assembling everything in the dish, covering it, and refrigerating overnight. In the morning, just slide it into a cold oven and bake for an extra 5–10 minutes. For long-term storage, freeze pre-baked portions wrapped in foil—thaw in the fridge overnight and reheat as above.
Final Thoughts
I still smile when I remember the first time I served this at a snowy holiday brunch—everyone went back for seconds (and thirds). This Sausage & Biscuit Breakfast Bake fills the kitchen with amazing aromas and wins hearts before you even slice into it. Whether you need Easy Breakfast Ideas for busy weekdays or a show-stopping Brunch Casserole for weekend gatherings, this recipe’s got your back. Give it a whirl, and let me know how many loyal fans you create in your crew!

Let us know how it was!FAQs
Can I make this breakfast casserole overnight?
Absolutely! Assemble the night before, cover it, and refrigerate. In the morning, bake at 350°F for 40–45 minutes. Your oven does the work while you hit snooze one more time. 🙂
Can I use frozen hashbrowns instead of biscuits?
Yes! Swap the biscuit quarters for 3 cups of thawed hashbrowns. Layer half before the egg mix and the rest on top, then bake until golden. This twist creates a crave-worthy crunch.
How can I make a vegetarian version?
Trade the sausage for seasoned crumbled tofu or plant-based sausage. Add extra veggies—bell peppers, mushrooms, and spinach work wonders—and you’ll still score rave reviews from meat-lovers.
What’s the best way to reheat leftovers?
For quick stovetop action, warm a slice in a nonstick skillet over medium heat until the edges crisp up. Otherwise, microwave for about 1 minute or reheat in a 350°F oven for 10 minutes. The casserole retains its charm either way.
