Step-by-Step Instructions 👩🍳
Prepare the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a 9 × 13-inch baking dish with butter or non-stick cooking spray.
Prepare the Potatoes 🥔
Peel the potatoes if desired and cut them into approximately 1-inch cubes.
Try to keep the pieces similar in size so they cook evenly.
Season the Potatoes 🌿
Place the diced potatoes in a large bowl.
Add the melted butter, heavy cream, garlic powder, onion powder, dried thyme, salt, and black pepper.
Toss thoroughly until the potatoes are evenly coated.
Assemble the Casserole 🥘
Transfer the seasoned potatoes to the prepared baking dish.
Spread them into an even layer.
Arrange the sliced smoked sausage evenly over the potatoes.
Cover and Bake 🔥
Cover the baking dish tightly with aluminum foil.
Bake at 400°F (200°C) for 35–40 minutes, or until the potatoes are tender when pierced with a fork.
Add the Cheese 🧀
Carefully remove the foil.
Sprinkle the freshly grated cheddar cheese evenly over the sausage and potatoes.
Finish Baking
Return the uncovered casserole to the oven.
Bake for another 5–10 minutes, until the cheese is completely melted, bubbling, and lightly golden.
For an extra browned cheese topping, you can broil it for 1–2 minutes while watching carefully.
Rest and Serve 🍽️
Remove the casserole from the oven and let it rest for approximately 5 minutes.
This allows the creamy sauce to settle slightly before serving.
Serve warm and enjoy!
Best Tips 💡
Cut the potatoes into uniform pieces so they cook at the same rate. Pieces that are too large may remain firm while smaller pieces become overly soft.
Freshly grated cheddar cheese generally melts more smoothly than pre-shredded cheese.
Keep the casserole covered during the first part of baking. The trapped steam helps the potatoes become tender.
If you want a crispier top, uncover the casserole for the final baking stage and briefly use the broiler.
Avoid adding too much salt before tasting because smoked sausage and cheddar cheese can already contain a significant amount of sodium.
Best Ingredient Options ⭐
Potatoes: Russet potatoes are excellent because their starch helps create a creamy texture. Yukon Gold potatoes are another great option and provide a naturally buttery flavor.
Sausage: Kielbasa works beautifully for a smoky, savory flavor. Andouille sausage can be used when you want a spicier casserole.
Cheese: Sharp cheddar gives the dish plenty of flavor. You can also use Monterey Jack, Colby Jack, mozzarella, or a Mexican cheese blend.
Cream: Heavy cream creates the richest result, while half-and-half can provide a lighter alternative.
Recipe Variations 🌶️
Cheesy Broccoli Version 🥦
Add broccoli florets during the final 20 minutes of covered baking for extra vegetables and color.
Spicy Sausage Casserole 🌶️
Use spicy Andouille sausage and add a pinch of crushed red pepper flakes or smoked paprika.
Tex-Mex Version 🌮
Use sliced chorizo instead of smoked sausage and replace the cheddar with a Mexican cheese blend.
Top the finished casserole with fresh cilantro, jalapeños, and a spoonful of sour cream.
Loaded Potato Version 🥓
Add green onions and extra cheese for a loaded baked-potato-inspired casserole.
What to Serve With 🥗
Because this casserole is rich and hearty, it pairs especially well with fresh and lighter side dishes.
A crisp garden salad with lemon vinaigrette provides a refreshing contrast.
Steamed broccoli, roasted green beans, or a simple cucumber salad are also excellent choices.
For an especially comforting dinner, serve it with warm crusty bread or homemade dinner rolls.
Make-Ahead Instructions 🕒
The casserole can be assembled up to 24 hours in advance.
Prepare the dish according to the recipe, but do not bake it.
Cover it tightly and refrigerate.
When ready to cook, place the casserole in the oven and add approximately 10–15 minutes to the covered baking time, checking that the potatoes are fully tender before adding the cheese.
Storage 🥡
Allow leftovers to cool before transferring them to an airtight container.
Store in the refrigerator for up to 4 days.
The flavors can become even more developed after a day in the refrigerator.
Reheating 🔥
For individual portions, microwave for approximately 1–2 minutes, or until heated through.
For larger portions, cover the casserole with foil and reheat at 350°F (175°C) for approximately 20 minutes.
Remove the foil during the final few minutes if you want to restore some of the crispy cheese topping.
Freezing ❄️
This casserole can be frozen, although the potatoes may become slightly softer after thawing.
Allow the casserole to cool completely, then wrap it tightly and freeze for up to 2 months for best quality.
Thaw overnight in the refrigerator before reheating.
Common Mistakes to Avoid 🚫
Undercooking the Potatoes
Do not add the cheese until the potatoes are tender. If the potatoes are still firm, continue baking before adding the cheese.
Cutting Potatoes Unevenly
Large and small pieces cook at different speeds. Keeping the cubes close to the same size helps ensure an even texture.
Over-Salting
Sausage and cheddar can already be salty, so season gradually and taste when possible.
Skipping the Resting Time
Allowing the casserole to rest for about 5 minutes helps the creamy mixture settle and makes serving easier.
Burning the Cheese
If using the broiler for extra browning, watch the casserole closely because cheese can go from golden to burnt very quickly.

Frequently Asked Questions ❓
Can I use milk instead of heavy cream?
Yes. Whole milk or half-and-half can be used for a lighter sauce.
The finished casserole will be less rich and may have a thinner consistency than when made with heavy cream.
Do I need to peel the potatoes?
No. Peeling is optional.
If you prefer a more rustic casserole, leave the skins on after thoroughly washing and scrubbing the potatoes.
Can I use Yukon Gold potatoes?
Absolutely. Yukon Gold potatoes are an excellent substitute for Russet potatoes and provide a naturally buttery flavor.
Why is my casserole watery?
Excess moisture can come from the potatoes or from using a thinner dairy product.
Pat washed potatoes dry before using them, and allow the finished casserole to rest for several minutes after baking.
Can I use a different sausage?
Yes. Kielbasa, Andouille, chicken sausage, turkey sausage, or another fully cooked smoked sausage can work well.
If using a raw sausage, make sure it is cooked safely and reaches the appropriate internal temperature.
Can I add vegetables?
Definitely. Broccoli, bell peppers, onions, mushrooms, or green beans can be incorporated to make the casserole more colorful and substantial.
