Ingredient Notes

• Crescent Roll Sheet – Using the seamless version keeps the crust even and easy to work with. If you only have regular crescent rolls, just pinch the seams together.
• Pre-Cooked Sausage – Any fully cooked sausage works here (links or crumbles). Turkey sausage or spicy varieties can switch up the flavor.
• Shredded Cheese – Use your favorite! Cheddar, pepper jack, or a blend all melt well and add richness.
• Milk – Whole milk adds the most creaminess, but 2% works too.
• Eggs – No need to separate—just beat slightly so they mix evenly into the casserole.

Before You Bake

Do I need to cook the sausage first?
Nope! Just make sure you’re using fully cooked sausage. If it’s raw, you’ll need to cook it before adding it to the casserole.

Can I prep this breakfast casserole the night before?
Yes! Assemble everything, cover tightly, and refrigerate overnight. Bake fresh in the morning—just add a few extra minutes to the cook time if it’s cold from the fridge.

What size pan should I use?
A standard 9×13-inch baking dish works best. If using a smaller pan, the casserole will be thicker and may need extra time.
