Cheesy Sausage and Potato Casserole
Smoky sausage, tender potatoes, creamy sauce, and plenty of melted cheese make Cheesy Sausage and Potato Casserole the kind of simple dinner everyone wants a second helping of.
The potatoes are partially cooked first so they become perfectly tender in the oven rather than staying hard in the middle.

It works especially well for:
- Busy weeknight dinners
- Sunday supper
- Potlucks
- Cold-weather meals
- Make-ahead dinners
- Family gatherings
- Leftover lunches
Serve it with a simple vegetable or salad and you have a complete comfort-food meal.

Ingredients
Sausage and Potatoes
- 14–16 ounces smoked sausage or kielbasa, sliced
- 2 pounds Yukon Gold potatoes, cut into bite-size pieces
- 1 tablespoon olive oil
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- ½ teaspoon smoked paprika
- ½ teaspoon black pepper
Creamy Cheese Sauce
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- ½ cup chicken broth
- 1 teaspoon Dijon mustard
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- 1½ cups shredded sharp cheddar cheese
- ½ cup sour cream
Topping
- 1 cup shredded cheddar
- ¼ cup grated Parmesan, optional
- Chopped parsley or green onions
Best Sausage to Use
Smoked Sausage
Smoked sausage is my first choice because it is flavorful and convenient.
Slice it into rounds about:
¼ to ½ inch thick
for even browning.
Kielbasa
Kielbasa works beautifully and gives the casserole a slightly garlicky, smoky flavor.
Chicken Sausage
Chicken sausage can make the casserole a little lighter.
Choose a fully cooked variety for the easiest preparation.
Turkey Sausage
Turkey smoked sausage works too.
Because it is often leaner, avoid overbrowning it.
Best Potatoes for the Casserole
Yukon Gold
My favorite choice.
They have a creamy texture and hold their shape well.
Red Potatoes
Red potatoes are also excellent if you want firmer chunks.
Russet Potatoes
Russets work, but they break down more easily.
They create a softer, more casserole-like texture.
How to Make Cheesy Sausage and Potato Casserole
Step 1: Preheat the Oven
Preheat the oven to:
375°F
Lightly grease a 9×13-inch baking dish.
Step 2: Prepare the Potatoes
Cut the potatoes into small, evenly sized pieces.
Place them in a pot of salted water.
Bring to a boil and cook for about:
7–9 minutes
You want them partially tender, not completely cooked.
They should still hold their shape.
Drain well.
Step 3: Brown the Sausage
Heat olive oil in a large skillet over medium-high heat.
Add sliced sausage.
Cook for approximately:
4–5 minutes
until lightly browned on both sides.
Transfer to a plate.
Step 4: Cook the Onion
In the same skillet, add diced onion.
Cook for about:
3–4 minutes
until softened.
Add garlic and cook another:
30 seconds.
Step 5: Make the Cheese Sauce
In a saucepan, melt butter over medium heat.
Whisk in flour.
Cook for about:
1 minute
to remove the raw flour taste.
Slowly whisk in:
- Milk
- Chicken broth
Continue whisking until smooth.
Step 6: Season the Sauce
Add:
- Dijon mustard
- Garlic powder
- Onion powder
- Smoked paprika
- Black pepper
Cook gently until the sauce begins to thicken.
Step 7: Add Cheese
Reduce heat to low.
Gradually add:
1½ cups cheddar
Stir until melted and smooth.
Remove from heat.
Stir in:
½ cup sour cream.
Step 8: Assemble the Casserole
Add the partially cooked potatoes to the prepared baking dish.
Add:
- Browned sausage
- Onion
- Garlic
Pour the cheese sauce over everything.
Gently toss until evenly coated.
Step 9: Add More Cheese
Sprinkle the top with:
- 1 cup cheddar
- Optional Parmesan
Step 10: Bake
Cover loosely with foil.
Bake at 375°F for about 20 minutes.
Remove the foil.
Continue baking another:
15–20 minutes
until the potatoes are tender and the cheese is melted and bubbling.
Step 11: Rest
Let the casserole rest for about:
10 minutes
before serving.
This allows the sauce to thicken slightly.
Step 12: Garnish
Top with:
- Parsley
- Green onions
- Extra black pepper
Serve hot.
The Secret to the Best Sausage Potato Casserole
Partially Cook the Potatoes
This is one of the most important steps.
Raw potato chunks can take much longer than expected to become tender inside a creamy casserole.
Parboiling removes the guesswork.
Brown the Sausage
Even though smoked sausage may already be fully cooked, browning adds extra flavor.
Shred Your Own Cheese
Freshly shredded cheddar usually melts more smoothly.
Keep the Sauce on Gentle Heat
Very high heat can make cheese sauces grainy.
Let the Casserole Rest
A few minutes of resting makes the sauce thicker and easier to serve.
Extra-Cheesy Sausage Potato Casserole
Increase the cheese to:
- 2 cups cheddar in the sauce
- 1½ cups cheddar on top
You can also add:
½ cup Monterey Jack
for extra meltiness.
Creamy Sausage Potato Casserole
For an even creamier casserole, add:
4 ounces cream cheese
to the sauce.
Whisk until smooth before adding the cheddar.
This creates a richer, thicker sauce.
Cheesy Kielbasa Potato Casserole
Replace smoked sausage with kielbasa.
Add:
- Extra garlic
- Black pepper
- Sharp cheddar
Kielbasa and potatoes are especially good together.
Sausage Potato Casserole With Broccoli
Add:
2–3 cups broccoli florets.
Blanch them briefly with the potatoes during the final few minutes.
Drain well before assembling.
This turns the casserole into more of a complete one-dish meal.
Sausage Potato Casserole With Green Beans
Add:
2 cups green beans.
Fresh or frozen both work.
If using frozen, thaw and drain first so they don’t release too much water.
Sausage Potato Casserole With Peppers
Add diced:
- Red bell pepper
- Green bell pepper
Cook them with the onion.
Peppers add sweetness and color.
Bacon Sausage Potato Casserole
Cook:
6 slices bacon
until crisp.
Crumble half into the casserole.
Sprinkle the rest over the top after baking.
For an extra-loaded version, add:
- Sour cream
- Green onions
- Cheddar
Ranch Sausage Potato Casserole
Add:
1 tablespoon ranch seasoning
to the cheese sauce.
Reduce extra salt because ranch seasoning can already be salty.
Top with:
- Cheddar
- Bacon
- Green onions
Garlic Butter Sausage Potato Casserole
Increase garlic to:
5 cloves
and add:
2 tablespoons melted garlic butter
to the potato mixture.
Finish with Parmesan.
Spicy Sausage Potato Casserole
Use spicy smoked sausage or andouille.
Add:
- Cayenne
- Red pepper flakes
- Pepper Jack
A little heat balances the creamy cheese sauce.
Cajun Sausage Potato Casserole
Use andouille sausage.
Season with:
- Cajun seasoning
- Smoked paprika
- Garlic
Use cheddar and Pepper Jack for the cheese.
Ham and Potato Casserole Variation
Replace the sausage with:
2 cups diced cooked ham.
This variation is especially useful after holiday dinners.
Chicken Sausage Potato Casserole
Use sliced fully cooked chicken sausage.
Good flavors include:
- Garlic herb
- Roasted pepper
- Mild Italian
Add spinach or broccoli for extra vegetables.
Sausage Hash Brown Casserole
Instead of diced potatoes, use:
frozen hash browns.
Thaw them first and squeeze out excess moisture.
Mix with:
- Sausage
- Cheese sauce
- Cheddar
Bake until golden and bubbly.
Sausage Tater Tot Casserole
Replace the potato chunks with frozen tater tots.
Prepare the sausage and creamy sauce.
Spread them in the casserole dish.
Arrange tater tots over the top.
Bake until crisp and golden.
Add cheese during the final portion of baking.
Cheesy Sausage and Potato Casserole Without Canned Soup
The main recipe uses a homemade sauce rather than condensed soup.
Butter, flour, milk, broth, cheese, and sour cream create a creamy base without needing canned soup.
If you prefer a shortcut version, you can use a condensed cream soup instead.
Shortcut Version With Cream Soup
Combine:
- 1 can cream of chicken or mushroom soup
- ½ cup sour cream
- ½ cup milk
- 1½ cups cheddar
Mix with the potatoes and sausage.
Top with extra cheese.
Bake as directed.
High-Protein Sausage Potato Casserole
To increase protein:
- Use extra sausage
- Choose chicken or turkey sausage with higher protein
- Add Greek yogurt instead of some sour cream
- Add cottage cheese blended into the sauce
- Serve with broccoli
You can also slightly reduce the amount of potatoes and increase the sausage.
Budget-Friendly Casserole
This recipe is naturally easy to stretch.
Use:
- Extra potatoes
- Store-brand cheese
- Frozen vegetables
- Less sausage
- More onion
Adding broccoli or green beans can increase the number of servings while keeping the meal affordable.
What to Serve With Cheesy Sausage Potato Casserole
Good sides include:
Green beans
Broccoli
Roasted Brussels sprouts
Garden salad
Coleslaw
Dinner rolls
Roasted carrots
Because the casserole is already rich, a simple vegetable side works best.

You can assemble the casserole up to a day ahead.
Prepare:
- Potatoes

Assemble in the baking dish.
Cover and refrigerate.
When ready to cook, let the dish sit out briefly while the oven preheats.
