BEST breakfast casserole!!

This is the BEST breakfast casserole I have ever had!!  It's a sausage, egg, and biscuit casserole and it's amazing!  I made it when my family was in town for Jackson's birthday (and am just getting around the putting the recipe up) and everyone gobbled it up.

1 lb bulk breakfast sausage (I always buy Jimmy Dean)
7 eggs
1 1/4 cup whole milk
3/4 cup heavy cream
1 tsp salt
1 tsp pepper
8 frozen buttermilk biscuits, partially thawed, halved
1 1/2 cups shredded cheddar cheese, divided

For the gravy:
3 Tbsp unsalted butter
3 Tbsp all purpose flour
2 cups whole milk
1 Tbsp chopped fresh sage
1/2 tsp red pepper flakes
salt and pepper to taste

Preheat oven to 375 degrees.  Coat a 7 x 11 inch baking dish with nonstick spray.  For the casserole, brown the sausage in a sauté pan over medium heat, breaking into chunks.  Transfer to a paper towel-lined plate.  Reserve drippings for gravy.

Whisk together eggs, milk, cream, salt and pepper in a large measuring cup.  Set aside.

Layer biscuit bottoms in prepared dish.  Sprinkle half the sausage over biscuits.  op with half of the cheddar and add biscuit tops.  Pour egg mixture over top.  Bake 30 minutes.  Sprinkle remaining cheddar over top and bake until center is set, 10-15 more minutes.  Let sit 10 minutes.

For the gravy, melt butter in reserved sausage drippings in a sauté pan over medium heat.  Whisk in flour until smooth, cook 2 minutes.  Slowly whisk in 2 cups milk until mixture is smooth.  Cook gravy until slightly thickened, 5-8 minutes.  Stir in sage and pepper flakes.  Season with salt and pepper to taste.

ENJOY every delicious bite!!!
