Step‑by‑Step Instructions for Savoury Sweet Potato Casserole with Crispy Sage and Bacon
Step 1: Preheat and Prepare
Begin by preheating your oven to 180°C (350°F). Line a baking tray with foil for easy cleanup. Next, wash the sweet potatoes thoroughly and place them on the tray. Roast the whole sweet potatoes for 1 to 1.5 hours, or until a fork easily pierces through them, indicating they’re tender and ready for mashing.
Step 2: Prepare the Crispy Sage
While the sweet potatoes roast, melt 4 tablespoons of salted butter in a medium pan over medium heat. Once melted, add fresh sage leaves and cook until they are crispy—about 3-4 minutes. Keep an eye on them to avoid burning, then strain the sage from the butter and set both aside; you’ll need them later for your Savoury Sweet Potato Casserole.
Step 3: Cook the Bacon
In a separate skillet, cook streaky bacon over medium heat until it's crispy, about 5-7 minutes, turning occasionally for even crispiness. Once done, transfer the bacon onto a paper towel-lined plate to absorb excess grease. Once cool, chop the bacon finely, and set it aside for the topping that will add a delightful savory kick!
Step 4: Make the Topping Mixture
In a mixing bowl, combine the crispy sage crumbles, panko breadcrumbs, grated Parmesan cheese, and minced garlic. Pour in the reserved browned butter, stirring well to coat everything. This mixture will form a delightful crunchy topping for your Savoury Sweet Potato Casserole, adding texture and flavor that balances the creamy mashed sweet potatoes below.
Step 5: Mash the Sweet Potatoes
Once the sweet potatoes are cool enough to handle, scoop the flesh into a large bowl. Add in the remaining browned butter, sour cream, and grated Parmesan cheese, followed by a pinch of salt and pepper. Use a potato masher or fork to mash until smooth and creamy, ensuring no lumps remain for that perfectly velvety base in your casserole.
Step 6: Layer the Casserole
In a greased baking dish, layer half of the mashed sweet potatoes first. Drizzle a bit of the reserved browned butter over this layer to enhance flavor. Add the remaining sweet potato mash on top, smoothing it out evenly. This layering will create a gorgeous base for the lovely crispy topping that follows.
Step 7: Bake and Finish
Sprinkle your prepared topping mixture evenly over the sweet potato mash. Bake the casserole in the preheated oven for about 25 minutes, or until the topping turns golden brown and crispy. Five minutes before it’s done, sprinkle the chopped crispy bacon on top for an extra savory punch that everyone will love.
Step 8: Serve and Enjoy
Once baked, carefully remove the casserole from the oven, letting it cool slightly before serving. The flavorful aroma of your Savoury Sweet Potato Casserole with Crispy Sage and Bacon will fill your kitchen, making it impossible to resist. Serve it warm, allowing everyone to dig into this delicious comfort food that’s perfect for gatherings!

Savoury Sweet Potato Casserole with Crispy Sage and Bacon Recipe FAQs
What is the best way to select sweet potatoes for this casserole?
Absolutely! When choosing sweet potatoes, look for firm and smooth-skinned ones without dark spots or blemishes. The sweeter and creamier the sweet potato, the better the flavor and texture for your casserole, so opt for the ones that feel heavy for their size.
