Sweet Potato Bake with Rosemary and Garlic Recipe
Introduction
This Sweet Potato Bake is a simple and flavorful side dish featuring tender, golden slices infused with garlic and rosemary. It’s perfect for cozy dinners or holiday meals, offering a delightful combination of crispy edges and soft centers.

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). Brush the base and sides of your skillet with a little olive oil to prevent sticking.
- Step 2: Slice the sweet potatoes into 3-4mm thick slices. Using a mandoline will make this step faster and ensure even slices.
- Step 3: Place the sliced potatoes in a large bowl. Add the melted butter, 1 tablespoon of olive oil, minced garlic, chopped rosemary, salt, and pepper. Toss well with your hands, making sure each slice is coated and separated.
- Step 4: Arrange the potato slices in the skillet in a circular, overlapping pattern for an attractive presentation.
- Step 5: Cover the skillet with foil and bake for 30 minutes, until the potatoes are nearly soft and almost cooked through.
- Step 6: Remove the foil and increase the oven temperature to 220°C (430°F) or 200°C for a fan oven. Brush the potatoes with the remaining tablespoon of olive oil.
- Step 7: Bake uncovered for another 20 minutes until the tops are golden brown and slightly crisp, and the potatoes are fully cooked. Test doneness by piercing with a knife or skewer.
- Step 8: Garnish with extra rosemary leaves, a sprig of rosemary, and a pinch of sea salt flakes if you like. Serve immediately to enjoy the crispy texture.
Tips & Variations
- Use a mandoline slicer to get even, thin slices which cook more uniformly.
- Add a sprinkle of Parmesan cheese before the final bake for a cheesy twist.
- Swap rosemary for thyme or sage for a different herb flavor.
- Include a pinch of smoked paprika in the seasoning for a subtle smoky note.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 180°C (350°F) to help restore some crispness, as the bake tends to soften in the fridge.

FAQs
Can I use regular potatoes instead of sweet potatoes?
Yes, regular potatoes can be used, but cooking times may vary slightly. Choose starchy varieties like Russet for the best texture.
How do I keep the top crispy after baking?
Serve the bake immediately after the final crisping step. The crispiness diminishes as it cools, but reheating in a hot oven can help revive some of the texture.

Ingredients
Sweet Potatoes
- 1.25 kg / 2.5 lb sweet potatoes (4–5 medium-sized)
Seasoning & Oil
- 30 g / 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
- Preheat Oven and Prepare Skillet: Preheat your oven to 180°C (350°F). Brush the base and sides of a skillet or oven-safe pan with a little olive oil to prevent sticking and add flavor.
- Slice the Sweet Potatoes: Using a sharp knife or mandoline slicer, slice the sweet potatoes into thin rounds about 3-4mm thick to ensure even cooking and layering.
- Toss with Seasonings: In a large bowl, combine the sliced sweet potatoes with the melted butter, 1 tablespoon of olive oil, minced garlic, chopped rosemary, kosher salt, and black pepper. Toss gently with your hands to coat each slice thoroughly and separate to avoid sticking.
- Layer in Skillet: Arrange the potato slices in the prepared skillet in a circular, overlapping pattern, creating an even layer that is both compact and aesthetically pleasing.
- Bake Covered for Initial Cooking: Cover the skillet with foil and bake at 180°C (350°F) for 30 minutes until the potatoes are soft but not fully cooked through.
- Increase Oven Temperature and Brush with Oil: Remove the foil, increase the oven temperature to 220°C (430°F) (or 200°C fan), and brush the potatoes with the remaining 1 tablespoon of olive oil to encourage browning and crispiness.
- Bake Uncovered to Finish: Bake the sweet potatoes uncovered for an additional 20 minutes until the tops turn golden brown and slightly crisp. Check doneness by piercing with a knife or skewer to ensure softness throughout.
- Garnish and Serve: Sprinkle additional fresh rosemary leaves and, if desired, a pinch of sea salt flakes on top. Serve immediately as the potatoes will lose crispiness as they cool.
Notes
- Using a mandoline slicer helps achieve uniformly thin slices for even cooking.
- Butter and olive oil together add depth and richness to the dish.
- Covering the dish during the first bake ensures the potatoes steam and soften evenly.
- Increasing oven temperature and brushing oil on top helps create a crispy, golden crust.
- Serve immediately for best texture, as the topping tends to soften when cooled.
- Rosemary can be adjusted or substituted with thyme for a different herbal aroma.
