Ingredients You’ll Need
Gathering these few but essential ingredients is all it takes to create the magic of this casserole. Each component plays a vital role in building layers of flavor, texture, and color that make this dish unforgettable.
- 1 pound ground sausage (mild or spicy): Adds rich, savory depth and a satisfying meaty texture that anchors the casserole.
- 1 can (15 oz) cut green beans, drained: Brings a pop of green color and a subtle crunch to lighten the hearty elements.
- 4 medium potatoes, diced (russet or Yukon gold): These tender cubes provide creamy, comforting starch to soak up all the flavors.
- 1 can (10.5 oz) cream of mushroom soup (or any cream soup you prefer): Acts as a luscious binder, adding moisture and earthiness to the dish.
- 1 cup shredded cheese (cheddar works wonderfully): Melts into a gooey, golden topping that brings everything together with its sharp, cheesy goodness.
- Salt and pepper to taste: Essential seasonings that enhance and balance all the flavors.
- Optional: Fresh herbs like parsley for garnish: Adds a burst of fresh color and subtle brightness at the end.
How to Make Sausage Green Bean Potato Casserole Recipe
Step 1: Cook the Sausage and Prepare the Potatoes
Start by browning the ground sausage in a large skillet over medium heat until it’s fully cooked and nicely browned, which brings out its wonderful savory flavor. While the sausage cooks, peel (if desired) and dice your potatoes evenly—using russet or Yukon gold will give you a perfect softness after baking. This step sets the foundation by combining that meaty, rich sausage flavor with tender potato chunks, key to the dish’s comforting vibe.
Step 2: Mix the Ingredients Together
In a large mixing bowl, combine your browned sausage, diced potatoes, drained green beans, and the cream of mushroom soup. Stir everything gently but thoroughly to coat all the ingredients in that creamy soup base. Season with salt and pepper to taste here—getting the seasoning just right at this stage ensures every bite is balanced and flavorful. This blend creates the perfect harmony between the creamy, the crunchy, and the meaty textures.
Step 3: Bake Until Golden and Bubbling
Transfer the mixture into a greased casserole dish and sprinkle the shredded cheddar cheese evenly over the top. Pop it into a preheated oven at 350°F (175°C) and bake for about 45 minutes, or until the cheese is melted, bubbly, and golden brown, and the potatoes are tender when pierced with a fork. This final step transforms the layered ingredients into a beautifully cohesive dish with a crispy, cheesy crust and a tender interior full of flavor.
How to Serve Sausage Green Bean Potato Casserole Recipe

Garnishes
A sprinkle of freshly chopped parsley or other fresh herbs on top adds a lovely pop of green color and a hint of brightness that enhances the rich, savory flavors perfectly. Garnishes can really elevate your presentation and stimulate your palate before you even take a bite.
Side Dishes
This casserole is quite filling on its own, but pairing it with a crisp green salad or some buttery dinner rolls balances the meal beautifully, introducing freshness and texture contrasts. Roasted carrots or a simple cucumber salad would work wonderfully for a complete spread.
Creative Ways to Present
Serve the casserole in individual ramekins for a charming and personal touch, especially for cozy dinner parties. You can also scoop it onto plates alongside a dollop of sour cream or a drizzle of hot sauce for those who enjoy a little extra kick. Presentation can be fun and brings extra delight to this homestyle classic.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer leftover casserole to an airtight container and store it in the refrigerator. It will stay fresh and flavorful for up to four days, making it a perfect next-day lunch or quick dinner solution.
Freezing
This Sausage Green Bean Potato Casserole Recipe freezes beautifully. For best results, assemble but don’t bake it, then wrap tightly in plastic wrap and foil before freezing. When you’re ready to enjoy, thaw overnight in the fridge and bake as directed, adding about 10-15 minutes to the baking time.
Reheating
Reheat leftovers in the oven at 350°F (175°C) to maintain that crispy cheesy top and warm through evenly. If you’re short on time, reheating in the microwave works well too, though the texture of the cheese topping will soften.
FAQs
Can I use fresh green beans instead of canned?
Absolutely! Fresh green beans add a wonderful texture and brightness. Just blanch or steam them briefly before mixing into the casserole to ensure tenderness after baking.
Is it okay to substitute the sausage with another protein?
Yes, you can swap the sausage for ground turkey, chicken, or even a plant-based meat alternative. Just be mindful of cooking times and seasoning adjustments to keep the dish flavorful.
Can I make this casserole gluten-free?
Definitely. Just make sure to use a gluten-free cream of mushroom soup or another type of gluten-free cream soup. The rest of the ingredients are naturally gluten-free.
What cheese works best for this casserole?
Sharp cheddar is a classic choice for its flavor and meltability, but feel free to experiment with mozzarella, Monterey Jack, or a blend for different cheesy notes and textures.
Can I prepare this casserole entirely ahead of time?
You can assemble the casserole a day before baking and keep it covered in the fridge. When ready to serve, just pop it in the oven and bake until bubbly and golden.
