Equipment You’ll Need

• 9×13-inch baking dish
• Large skillet (at least 12 inches)
• Whisk
• Mixing bowl
• Measuring cups and spoons
• Spatula

Ingredients

• 1 lb bulk pork breakfast sausage
• 1/3 cup all-purpose flour
• 4 cups whole milk
• 1 tsp freshly ground black pepper, plus more to taste
• 1/2 tsp salt, plus more to taste
• Pinch of cayenne pepper (optional)
• 1 (16.3 oz) can refrigerated buttermilk biscuits (8 count)
• 8 large eggs
• 1/4 cup milk
• 1 1/2 cups shredded sharp cheddar cheese, divided
• 2 tbsp chopped fresh chives or parsley, for garnish

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. In a large skillet over medium-high heat, cook the pork sausage, breaking it apart with a spoon, until it is browned and cooked through, about 8-10 minutes. Do not drain the fat.
3. Sprinkle the flour over the cooked sausage and its renderings in the skillet. Stir constantly for 1-2 minutes until the flour is fully incorporated and cooked. This creates the roux.
4. Gradually pour in the 4 cups of whole milk while whisking constantly to prevent lumps. Continue to cook, stirring frequently, until the gravy comes to a simmer and has thickened, about 5-7 minutes. Stir in the black pepper, salt, and cayenne (if using). Taste and adjust seasoning as needed. Remove from heat.
5. While the gravy thickens, separate the biscuits and cut each one into quarters. Arrange the biscuit pieces in a single, even layer in the bottom of the prepared baking dish.
6. In a separate mixing bowl, whisk together the 8 large eggs and the 1/4 cup of milk until smooth. Season with a pinch of salt and pepper.
7. Pour the egg mixture evenly over the biscuit pieces in the baking dish. Sprinkle 1 cup of the shredded cheddar cheese over the eggs.
8. Carefully pour the prepared sausage gravy evenly over the cheese and egg layer.
9. Sprinkle the remaining 1/2 cup of cheddar cheese over the top of the gravy.
10. Bake for 25-30 minutes, or until the casserole is hot, bubbly, and the top is golden brown. The center should be set.
11. Let the casserole rest for 10 minutes before slicing. Garnish with fresh chives or parsley before serving.

Expert Cooking Tips

• Don’t drain the sausage grease! The fat is essential for creating a flavorful roux, which is the base of your gravy.
• For the smoothest gravy, warm your milk slightly before adding it to the skillet. Adding cold milk to a hot roux can sometimes cause lumps.
• If you prefer a thicker gravy, allow it to simmer for a few extra minutes. If it gets too thick, simply thin it out with a splash more milk.
• Letting the casserole rest after baking is crucial. It allows the layers to set, ensuring clean, beautiful slices.

Substitutions and Variations

For a different flavor, try using hot Italian sausage or a maple-flavored breakfast sausage. Turkey sausage can be used for a leaner option, but you may need to add 2 tablespoons of butter to the pan to make the gravy roux. Any good melting cheese like Monterey Jack, Colby, or a Mexican blend can be substituted for the cheddar.

Common Mistakes to Avoid

The most common mistake is under-seasoning the gravy. Sausage gravy needs a generous amount of black pepper to achieve its signature flavor. Be sure to taste the gravy before assembling the casserole and adjust the salt and pepper levels. Another pitfall is not cooking the flour long enough in the roux step; cooking it for at least a minute gets rid of any raw flour taste.

Serving Suggestions

This is a hearty, all-in-one meal. To round it out, serve it with a fresh fruit salad to provide a light, sweet contrast to the savory richness of the casserole. A simple green salad with a vinaigrette dressing also pairs nicely. For beverages, a strong cup of hot coffee or a glass of fresh orange juice is classic.

Storage and Reheating Tips

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 1-2 minutes or in an oven preheated to 350°F (175°C) until warmed through. You can also freeze the baked casserole for up to 2 months; thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, this recipe is perfect for making ahead. You can fully assemble the casserole (without baking), cover it tightly, and refrigerate it for up to 24 hours. When ready to bake, let it sit at room temperature for 30 minutes, then bake as directed, possibly adding 5-10 minutes to the total cook time.

Can I use homemade biscuits?

Absolutely. If using homemade biscuit dough, you can either arrange the raw, cut dough in the pan as directed, or for a guaranteed fully-cooked base, you can par-bake the biscuits for about 10 minutes before adding the egg, gravy, and cheese layers.

My gravy seems lumpy. How can I fix it?

The key to preventing lumps is to add the milk slowly and whisk constantly. If you do end up with a few lumps, you can often whisk them out vigorously. For a very lumpy gravy, you can pour it through a fine-mesh sieve before adding it to the casserole.
