Ingredients for Biscuits and Gravy Casserole Recipe
Gluten-free breakfast sausage: A savory sausage that is free from gluten, providing the main protein for the dish.
Gluten-free all-purpose flour: A versatile flour blend that thickens the gravy while keeping it gluten-free.
Milk: Adds creaminess to the gravy, balancing the flavors.
Salt: Enhances the overall flavor of the dish.
Pepper: Adds a touch of spice and depth to the gravy.
Gluten-free biscuit mix: The base for the biscuits, ensuring they are fluffy and gluten-free.
Shredded cheddar cheese: Adds a rich, cheesy topping to the casserole.
Technique Tip for This Casserole
When making the sausage gravy, be sure to cook the gluten-free flour with the sausage for at least 1-2 minutes before adding the milk. This step helps to eliminate any raw flour taste and ensures a smoother, more flavorful gravy.

Alternative Ingredients
gluten-free breakfast sausage - Substitute with ground turkey: Ground turkey is a leaner option and can be seasoned to mimic the flavors of breakfast sausage.
gluten-free all-purpose flour - Substitute with cornstarch: Cornstarch is a great thickening agent and works well in gravies, providing a smooth texture.
milk - Substitute with unsweetened almond milk: Unsweetened almond milk is a dairy-free alternative that maintains the creamy texture needed for the gravy.
gluten-free biscuit mix - Substitute with gluten-free pancake mix: Gluten-free pancake mix can be used to create a similar doughy texture for the biscuits.
shredded cheddar cheese - Substitute with shredded mozzarella cheese: Shredded mozzarella cheese melts well and provides a mild flavor that complements the dish.

How to Store / Freeze This Casserole
- Allow the biscuits and gravy casserole to cool completely before storing. This prevents condensation, which can make the biscuits soggy.
- Transfer the casserole to an airtight container. If the baking dish has a tight-fitting lid, you can store it directly in the dish.
- Store the casserole in the refrigerator for up to 3-4 days. This ensures the sausage gravy and biscuits remain fresh and safe to eat.
- For longer storage, consider freezing the casserole. Wrap the entire dish tightly in plastic wrap, then cover with aluminum foil to prevent freezer burn.
- If you prefer to freeze individual portions, cut the casserole into serving sizes and wrap each piece in plastic wrap before placing them in a freezer-safe bag or container.
- Label the container with the date to keep track of its freshness.
- When ready to enjoy, thaw the casserole in the refrigerator overnight. This gradual thawing helps maintain the texture of the biscuits and gravy.
- Reheat in the oven at 350°F (175°C) until warmed through, approximately 20-25 minutes. Cover with foil to prevent the biscuits from over-browning.
- Alternatively, you can reheat individual portions in the microwave. Place a piece on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power until hot, about 2-3 minutes.
- For a crispier top, you can finish reheating individual portions in the oven or under the broiler for a few minutes after microwaving.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover biscuits and gravy casserole in an oven-safe dish. Cover with aluminum foil to prevent the biscuits from drying out. Heat for about 20-25 minutes or until warmed through.
For a quicker option, use the microwave. Place a portion of the casserole on a microwave-safe plate. Cover with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking and stirring halfway through to ensure even heating.
If you have an air fryer, preheat it to 350°F (175°C). Place the casserole in the air fryer basket, ensuring the biscuits are not overcrowded. Heat for about 5-7 minutes, checking halfway through to ensure they are not overcooking.
For stovetop reheating, place the casserole in a skillet over medium-low heat. Cover with a lid and heat for about 10-15 minutes, stirring occasionally to ensure even heating. This method helps maintain the biscuits' texture while warming the gravy thoroughly.
If you prefer a toaster oven, preheat it to 350°F (175°C). Place the casserole on a baking sheet and cover with foil. Heat for 15-20 minutes, checking to ensure the biscuits are not over-browning.
