🛒 Ingredients

Here’s what you’ll need for one casserole (serves 8–10):

For the Casserole:

• 1 can refrigerated biscuits, chopped into bite-size pieces
• 2 lbs cooked sausage (I like using breakfast sausage, but any ground sausage works)
• 1 cup shredded cheese (cheddar, Colby Jack, or whatever you have)
• 6 eggs
• ½ cup milk

For the Homemade Gravy:

• Sausage drippings (from the cooked sausage)
• ½ cup flour
• 1 tsp salt
• 2 cups milk

Tip: If your sausage doesn’t give off enough grease, you can supplement with butter. The flavor will still be amazing!

👩‍🍳 How to Make It

1. Preheat and Prep

Preheat your oven to 350°F and grease a 9×13 baking dish (or similar size). I like to use a little bit of the sausage drippings for flavor.

2. Layer the Base

Chop the biscuits into quarters or bite-sized pieces and spread them evenly in the bottom of the baking dish.

3. Add the Sausage & Cheese

Sprinkle the cooked sausage over the biscuit pieces, followed by a layer of shredded cheese. Don’t worry if it looks piled high — it all melts together beautifully.

4. Whisk the Eggs

In a small bowl, whisk together the eggs and ½ cup of milk. Pour this mixture evenly over the sausage and cheese layers.

5. Make the Gravy

In the same skillet you cooked the sausage, add the flour to the sausage drippings and whisk to make a roux. Cook for 1–2 minutes, then slowly whisk in the 2 cups of milk. Stir constantly until the gravy thickens (about 5 minutes). Season with salt.

This gravy is rich, creamy, and pulls the whole casserole together. It’s worth the extra step — and so much better than a packet!

6. Top and Bake

Pour the gravy evenly over the casserole. Bake uncovered at 350°F for 35–45 minutes, or until the top is golden and the center is set.

7. Cool & Serve

Let the casserole cool for 5–10 minutes before slicing and serving. The biscuits will be fluffy on the inside, crispy on the edges, and soaked with all that delicious flavor.

📝 Make-Ahead Tips

This casserole is ideal for busy mornings or holiday brunch prep. Here’s how to make it ahead:

• Fully Bake: Assemble and bake the casserole as instructed.
• Cool Completely: Let it cool, then cover and refrigerate overnight.
• Reheat: Cover with foil and bake at 350°F for 15–20 minutes, removing the foil for the last 5 minutes to re-crisp the top.

You can also bake it in advance, slice it into squares, and store individual servings for easy grab-and-go breakfasts throughout the week.

🔄 Variations & Add-Ins

This recipe is super flexible! Here are a few ideas to switch things up:

• Add Veggies: Try sautéed bell peppers, onions, or spinach mixed in with the sausage.
• Swap the Cheese: Pepper Jack, mozzarella, or a Mexican blend all work great.
• Spice it Up: Add a dash of hot sauce to the eggs or mix chopped jalapeños into the sausage.
• Use Homemade Biscuits: If you have time, you can absolutely use scratch-made biscuit dough.
