👩‍🍳 Variations

This baked breakfast casserole is easily adaptable.

Using different types of cheese, such as mozzarella or swiss adds amazing flavor. For an even creamier consistency, try using Gruyere or Monterey Jack.
I've had best results using half & half, but both whole and 2% milk can be substituted. If using heavy whipping cream, this sausage egg bake will need to cook a bit longer.
Want to add some veggies? Chopped mushrooms, peppers, zucchini, and onions taste great! If adding asparagus and spinach, add while cooking the sausage to help soften the texture.
Substituting turkey sausage or bacon tastes great in this sausage and egg casserole.

📋 Step-By-Step Recipe instructions

Start by preheating the oven to 425°F. In a skillet, cook the raw sausage over medium heat until done. Ensure there are no traces of pink. Set aside.

Using a cheese grater, freshly grate the Pepper Jack and mild cheddar cheese. Place the shredded cheese in separate bowls and set aside.

Place the raw Grands biscuits in the center of a 9x13 baking dish. Using your hands, gently spread the raw biscuit dough until each biscuit is evenly spread across the baking dish. Using your fingers, firmly press and pinch the corners to seal along the sides and in the middle.

Next, evenly sprinkle on the cooked sausage, the shredded Pepper Jack, and cheddar cheese over the raw biscuits. Set aside.

In a large bowl, whisk the eggs, half and half, dry mustard, salt, and pepper until well combined.

Expert Tip! While hand whisking works well, using a standing or hand held electric mixer works better to ensure the ingredients are well combined and the ground mustard does not clump.

From there, evenly pour the egg mixture on top of the biscuits, sausage, and cheese.

Place the sausage egg casserole in the oven and bake for 25-30 minutes or until set.

Expert Tip! You'll know it's done when the top is golden brown and the sides are bubbling. There should be no soft egg batter consistency at the top of the casserole.

🙋 Recipe FAQs

Can Sausage Egg Casserole be frozen?

Yes! After cooking and letting it completely cool, wrap the individual pieces in plastic wrap and place in the freezer for up to 3 months.

Is it better to freeze this casserole cooked or uncooked?

Either method works well. I covered how to freeze cooked pieces above. For uncooked, prepare the casserole in a 9x13 freezer safe dish and cover with aluminum foil. Place in the freezer for up to 3 month. To thaw, place the casserole in the refrigerator. Once completely thawed, cook according to instructions in the recipe card.

How long does Sausage Egg Casserole last in the fridge?

Place any leftovers in an airtight container with a lid in the refrigerator for up to 3 days.

💭 Expert Tips

To save time, use pre-crumbled and cooked pork sausage.
Substitute HOT sausage if you want more of a kick. For more of a sweet and savory flavor, use maple pork sausage.
Freshly grated cheese tastes better than packaged shredded cheese. Fresh is always best.
When cooking, one corner of the casserole will bubble up. This is normal. As it cools, it will fall.
Don't use frozen biscuits. Use the biscuits in the refrigerator section of the grocery store so the dough expands properly.
Do not cover when cooking.
You can make this sausage egg casserole 24 hours ahead of time before cooking. Simply layer the biscuit dough on the bottom of the baking dish and add the cooked sausage and shredded cheese. Combine the egg mixture and pour on top of the casserole. Cover with aluminum foil and store in the refrigerator until ready to cook.
Reheat individual slices in the microwave for 30-seconds or until hot. To reheat the entire casserole, cover it with aluminum foil and bake it in the oven at 350°F for 20 minutes.
