Ingredients You’ll Need
Getting the ingredients right is the secret to nailing this Savoury Sweet Potato Casserole Recipe. Each component brings something vital—whether it’s creaminess, a hit of umami, or that satisfying crispy top. Let’s dive into what makes this dish so special.
- Sweet potatoes (1.75kg / 3.5lb): The star of the dish, they offer a natural sweetness and creamy base once mashed.
- Sour cream (1/2 cup / 115g): Adds tangy richness that balances the sweetness perfectly.
- Parmesan cheese (2 parts: 1/2 cup grated and 1/2 cup finely grated): Provides a nutty, salty depth throughout the casserole and topping.
- Garlic cloves (2, finely minced): Infuses a subtle garlicky warmth that lifts the flavor.
- Salt (3/4 tsp plus 1/4 tsp in topping): Enhances all the flavors seamlessly.
- Black pepper (1/4 tsp plus 1/4 tsp in topping): Adds a gentle heat and complexity to keep it interesting.
- Butter (250g / 8oz, salted, cut into 2cm cubes): Crucial for richness and a silky texture in the mash, plus flavor in the sage butter topping.
- Sage leaves (15): The herb that brings an earthy, aromatic note that pairs beautifully with sweet potato.
- Panko breadcrumbs (3/4 cup): For that golden, crunchy topping that makes every bite a delight.
- Bacon (150g / 5oz, streaky, cooked and finely chopped): Adds a smoky, salty punch that takes the dish to another level.
How to Make Savoury Sweet Potato Casserole Recipe
Step 1: Prepare and Cook the Sweet Potatoes
Start by peeling and chopping your sweet potatoes into evenly sized chunks. Place them in a large pot, cover with cold water, and bring to a gentle boil. Let them cook until they’re tender and easily pierced with a fork. This step is the foundation, ensuring that your sweet potatoes mash into a creamy, smooth base that’s essential to the casserole’s texture.
Step 2: Make the Sage Butter
While the sweet potatoes cook, melt your cubes of salted butter in a small pan over medium heat. Add the fresh sage leaves and let them infuse the butter until the leaves become crisp and golden. This sage butter will be folded into the sweet potatoes and also used to flavor the breadcrumb topping. The aroma here is incredible and really sets the tone for the entire dish.
Step 3: Mash and Mix the Sweet Potatoes
Drain the cooked sweet potatoes and mash them thoroughly while still warm. Stir in the sour cream, freshly grated Parmesan, minced garlic, salt, black pepper, and half of the crispy sage butter (reserve the rest for later). This combination creates a luscious, flavorful mash that balances creamy and cheesy notes with that herby butter magic.
Step 4: Prepare the Topping
In a small bowl, toss the panko breadcrumbs with the remaining sage butter, finely grated Parmesan, salt, pepper, and the crispy chopped bacon. This mixture will create a wonderfully crunchy, savory topping that contrasts beautifully with the soft sweet potato base underneath.
Step 5: Assemble and Bake
Spread your sweet potato mash evenly in a buttered casserole dish. Sprinkle the bacon-breadcrumb topping generously over the top. Pop it into a preheated oven and bake at 180°C (350°F) for about 30-40 minutes, or until the topping is golden brown and crispy. The result is a bubbling, beautiful casserole ready to impress!
How to Serve Savoury Sweet Potato Casserole Recipe
Garnishes
For that extra pop of freshness, sprinkle some finely chopped fresh parsley or chives over the top right before serving. A little fresh herb brightens the rich casserole and makes it look inviting on the plate.
Side Dishes
This casserole pairs wonderfully with simple salads or roasted vegetables. Consider a crisp green salad with vinaigrette or tender roasted Brussels sprouts to add contrast in texture and color on your plate.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftover Savoury Sweet Potato Casserole Recipe can be stored in an airtight container in the refrigerator for 3 to 4 days. Make sure it cools completely first to keep that creamy texture intact when you reheat it.
Freezing
This casserole freezes beautifully! Portion it out into freezer-safe containers and freeze for up to 2 months. Just thaw in the fridge overnight before reheating to preserve the flavors and texture.
Reheating
Reheat in the oven at 160°C (320°F) until warmed through and crispy on top, or microwave individual portions for convenience. If the topping softens during refrigeration, a quick blast in the oven will bring back that crunch.
FAQs
Can I make this casserole dairy-free?
Absolutely! Swap the sour cream with a dairy-free alternative like coconut yogurt, and use dairy-free butter and Parmesan substitutes. The sage and bacon flavors still shine through, making it just as tasty.
Is bacon necessary for the recipe?
Bacon adds a smoky, salty element that really enhances the dish, but you can omit it for a vegetarian version. Adding extra sage or a touch of smoked paprika can help build up that depth of flavor without the bacon.
Can I use frozen sweet potatoes?
Fresh sweet potatoes yield the best texture and flavor, but if you use frozen, make sure to thaw and drain them well before mashing to avoid excess moisture in the casserole.
How spicy is the Savoury Sweet Potato Casserole Recipe?
This casserole is mild and more about comforting, savory flavors than heat. The black pepper adds just a subtle warmth that complements the dish without overpowering.
Can I prepare this recipe ahead of time?
Yes, you can prepare the sweet potato mash and topping separately a day in advance. Assemble just before baking for the best texture and flavor. This makes it a great choice for busy holiday meals or entertaining.
