Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish with butter or nonstick cooking spray.
Set the dish aside while you prepare the potatoes and sausage.
Step 2: Prepare the Potatoes
Wash and peel the potatoes if desired.
Slice them thinly or cut them into small cubes.
Thin slices create a layered casserole, while diced potatoes give a heartier texture.
Try to keep the pieces close in size so they cook evenly.
Step 3: Cook the Sausage and Onion
Heat olive oil or butter in a large skillet over medium heat.
Add the sliced sausage and cook for 4–5 minutes, until lightly browned.
Add the diced onion and cook for another 3–4 minutes, until softened.
Stir in the minced garlic and cook for 30 seconds.
Remove from heat.
This step adds extra flavor because browning the sausage creates a richer taste.
Step 4: Make the Creamy Sauce
In a large mixing bowl, combine:
- Heavy cream
- Whole milk
- Sour cream
- Cream cheese
- Chicken broth
- Parmesan cheese
- Dijon mustard
Whisk until mostly smooth.
Add the salt, black pepper, garlic powder, onion powder, paprika, Italian seasoning, and dried parsley.
Mix again until combined.
The sauce should be creamy and pourable.
Step 5: Assemble the Casserole
Place half of the potatoes in the bottom of the prepared baking dish.
Add half of the sausage and onion mixture.
Sprinkle with some cheddar cheese.
Repeat with the remaining potatoes and sausage.
Pour the creamy sauce evenly over the top.
Use a spoon or spatula to gently spread the sauce so it reaches all corners of the dish.
Step 6: Add the Cheese Topping
Sprinkle the remaining cheddar cheese and mozzarella cheese over the top.
Make sure the cheese is evenly spread.
This will create the golden, bubbly topping that makes the casserole so delicious.
Step 7: Bake Covered
Cover the baking dish tightly with aluminum foil.
Bake for 35–40 minutes.
This allows the potatoes to cook through without drying out.
Step 8: Bake Uncovered
Remove the foil.
Bake for another 10–15 minutes, or until the cheese is melted, bubbly, and lightly golden.
The potatoes should be fork-tender.
If you want a darker golden top, broil for 2–3 minutes at the end.
Watch carefully so the cheese does not burn.
Step 9: Rest Before Serving
Remove the casserole from the oven.
Let it rest for 10 minutes before slicing.
This helps the sauce thicken and makes the casserole easier to serve.
Step 10: Garnish and Serve
Sprinkle with fresh parsley if desired.
Serve warm and enjoy.

Bake as directed, adding an extra 5–10 minutes if needed.
Storage
Let leftovers cool completely.
Store in an airtight container in the refrigerator for up to 4 days.
The sauce will thicken as it chills, but it becomes creamy again when reheated.
Reheating
Oven Method
Place leftovers in an oven-safe dish.
Cover with foil.
Reheat at 350°F (175°C) for 15–20 minutes, or until warm.
Remove foil during the last few minutes if you want the top to crisp again.
Microwave Method
Place one portion on a microwave-safe plate.
Heat for 1–2 minutes, or until hot.
Add a splash of milk or cream if needed.
Air Fryer Method
Reheat a small portion at 325°F (160°C) for 5–7 minutes.
This works best if you want the top slightly crispy.

Freeze for up to 2 months.
Thaw overnight in the refrigerator before baking.

The texture may be slightly softer after freezing, but the flavor will still be delicious.
Common Mistakes to Avoid
Cutting Potatoes Too Thick
Thick potato slices take longer to cook.
Slice thinly or dice small for best results.
Not Covering While Baking
Covering helps the potatoes cook through.
If you bake uncovered from the beginning, the cheese may brown before the potatoes are tender.
Using Too Little Seasoning
Potatoes need enough seasoning to taste flavorful.
Season the sauce well.
Skipping the Sausage Browning
Browning adds flavor and improves texture.
It is worth the extra few minutes.
Not Letting It Rest
Resting helps the sauce thicken.
If you cut it immediately, it may look too loose.
