Golden Roasted Sweet Potato Bake with Garlic and Rosemary Recipe
Introduction
This Sweet Potato Bake is a flavorful and easy side dish that combines tender, fragrant sweet potatoes with garlic, rosemary, and a touch of butter and olive oil. Baked until golden and slightly crisp on top, it’s perfect for any meal and sure to impress your family or guests.

Ingredients
- 1.25 kg / 2.5 lb sweet potatoes (4-5 medium)
- 30g / 2 tbsp unsalted butter, melted
- 2 garlic cloves, finely minced
- 2 tbsp olive oil, plus extra for brushing the skillet
- 3/4 tsp kosher or cooking salt
- 1/4 tsp black pepper
- 1 tbsp rosemary leaves, finely chopped, plus more for garnish
Instructions
- Step 1: Preheat your oven to 180°C (350°F). Lightly brush the base and sides of a skillet with olive oil to prevent sticking.
- Step 2: Slice the sweet potatoes into 3-4mm thick rounds. Using a mandoline makes this faster and ensures even slices.
- Step 3: In a large bowl, combine the sliced potatoes with melted butter, 1 tablespoon olive oil, minced garlic, chopped rosemary, salt, and pepper. Toss gently with your hands to coat each slice evenly, separating them as you mix.
- Step 4: Arrange the potato slices in the skillet in a circular, overlapping pattern to cover the base completely.
- Step 5: Cover the skillet with foil and bake for 30 minutes. The potatoes should be soft but not fully browned yet.
- Step 6: Remove the foil and increase oven temperature to 220°C (430°F) or 200°C (fan). Brush the potato surface with the remaining 1 tablespoon of olive oil.
- Step 7: Bake uncovered for another 20 minutes until the top is golden and slightly crisp. Test doneness by piercing a slice with a knife or skewer—it should slide in easily.
- Step 8: Garnish with extra rosemary leaves, a sprig of rosemary, and a pinch of sea salt flakes if desired. Serve immediately for the best texture, as the crispiness softens as it cools.
Tips & Variations
- For extra flavor, try adding a sprinkle of smoked paprika or a dash of cayenne pepper to the seasoning mix.
- If you don’t have a mandoline, use a sharp knife and steady hands to slice the potatoes evenly.
- Swap rosemary for thyme or sage for a different herbal note.
- Use a cast iron skillet if available for better heat distribution and an extra crispy edge.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a low oven or toaster oven to restore some crispiness. Avoid microwaving, as it can make the potatoes soggy.

FAQs
Can I prepare this dish ahead of time?
Yes, you can assemble the potatoes in the skillet and refrigerate covered overnight. Bake as directed, adding a few extra minutes to the cooking time if baking straight from the fridge.
Can I use regular potatoes instead of sweet potatoes?
Yes, regular potatoes can be used, but baking times may vary. They typically take a bit longer to become tender and crispy, so check doneness carefully and adjust baking time as needed.
