Key Ingredients & Substitutions
Biscuit Dough: Refrigerated biscuits are perfect for a quick base. If you want a homemade touch, you can use your favorite biscuit recipe. For gluten-free needs, look for gluten-free ready-made biscuit dough or make your own with gluten-free flour.
Sausage: Breakfast sausage adds great flavor and fat for the gravy. Poultry sausage works well for a leaner option. You can also use plant-based sausage if you want a vegetarian variant, though cooking times may vary.
Milk: Whole milk gives the richest gravy, but 2% or even unsweetened plant milk (like oat milk) can work if you prefer. Avoid flavored milk for best results.
Flour: All-purpose flour thickens the gravy nicely. For a gluten-free option, try a gluten-free blend or cornstarch mixed with water, added gradually to avoid lumps.
Cheese: Cheddar adds a classic sharpness and melts beautifully. Feel free to switch it up with Monterey Jack, Colby, or a blend. If dairy-free, use vegan cheese blends designed for melting.
How Do I Make Sausage Gravy Smooth and Creamy Without Lumps?
Making gravy can be tricky if lumps form. Here’s how I get it smooth:
- After cooking the sausage, sprinkle the flour evenly over the meat and stir constantly for at least 1-2 minutes. This cooks out the raw flour taste and helps prevent lumps.
- Slowly add the milk bit by bit while whisking continually. This gradual mixing helps the flour absorb the milk smoothly without clumping.
- Keep stirring frequently as the gravy thickens over medium heat. If lumps appear, whisk rapidly or break them up gently with a spoon.
- If the gravy gets too thick, add a little more milk while stirring until you reach your desired consistency.
Patience and constant stirring are key. This way, the gravy stays creamy and coats the biscuit base perfectly!
Equipment You’ll Need
- 8-inch round baking dish or casserole dish – perfect size for a cozy breakfast casserole.
- Large skillet – great for cooking the sausage evenly and making the gravy.
- Whisk – essential to mix the flour and milk smoothly, so no lumps form.
- Spoon or spatula – helpful for stirring the sausage and scraping the gravy.
- Measuring cups and spoons – to get your ingredients just right every time.
Flavor Variations & Add-Ins
- Swap breakfast sausage for cooked bacon or ham for a smoky twist.
- Add chopped green bell peppers or sautéed mushrooms for extra veggies and texture.
- Use pepper jack cheese instead of cheddar to add a little spicy kick.
- Stir in chopped fresh herbs like thyme or sage to brighten the gravy’s flavor.

- 2 ½ cups milk (whole or 2%)

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and about 25-30 minutes to bake. Altogether, you should set aside around 40-45 minutes from start to finish, making it a quick, satisfying breakfast or brunch option.
Step-by-Step Instructions:
1. Preheat Oven and Prepare Pan:
Begin by preheating your oven to 350°F (175°C). Lightly grease an 8-inch round baking dish or a similar-sized casserole dish to prevent sticking.
2. Prepare the Biscuits:
Open the can of refrigerated biscuit dough and separate the biscuits. Arrange them evenly in the prepared baking dish, pressing them lightly together to form a close-knit base.
3. Cook the Sausage:
Heat a large skillet over medium heat. Add the ground breakfast sausage and cook, breaking it apart with a spoon, until browned and fully cooked. Drain any excess grease if needed.
4. Make the Sausage Gravy:
Sprinkle the all-purpose flour over the cooked sausage in the skillet. Stir well and cook for 1-2 minutes to eliminate the raw flour taste. Gradually whisk in the milk, stirring frequently until the mixture thickens—approximately 5-7 minutes. Season with salt, black pepper, and optional garlic powder.
5. Assemble the Casserole:
Pour the sausage gravy evenly over the biscuit layer in the baking dish. Sprinkle the shredded cheddar cheese evenly on top of the gravy.
6. Bake:
Place the casserole in your preheated oven and bake for 25-30 minutes or until the biscuits are cooked through and the top is golden brown with melted, bubbly cheese.
7. Garnish and Serve:
Remove the casserole from the oven and allow it to cool for a few minutes. Garnish with fresh chopped parsley or chives if desired. Serve warm and enjoy your comforting breakfast treat!
Can I Use Frozen Biscuits for This Casserole?
It’s best to use refrigerated biscuit dough for this recipe since frozen biscuits may not bake evenly or absorb the gravy properly. If you only have frozen biscuits, make sure to thaw them fully in the fridge before assembling the casserole.
Can I Prepare This Casserole Ahead of Time?
Yes! Assemble the casserole the night before, cover it tightly, and refrigerate. In the morning, bake it directly from the fridge, adding a few extra minutes to the baking time until the biscuits are cooked through and cheese is bubbly.
How Should I Store and Reheat Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave or oven until heated through, adding a splash of milk if the gravy seems too thick.
Can I Substitute the Sausage for a Vegetarian Option?
Absolutely! Use your favorite plant-based sausage or sautéed mushrooms and season them well to mimic the savory flavor. The rest of the recipe stays the same, and it still tastes delicious.
