Ingredients
For the crispy sweet potato roast, you’ll need:
- 3 tablespoons salted or unsalted butter, melted
- 3 tablespoons olive oil
- Coarse salt and freshly ground black pepper or red pepper flakes, to taste
- 5 pounds sweet potatoes, peeled and thinly sliced
- 2 shallots, peeled and thinly sliced (optional, for aromatic flavor)
Optional: Herby Salsa Verde
- 1 scant cup parsley leaves
- 1 tablespoon fresh rosemary
- 1 generous teaspoon each of fresh thyme and sage leaves
- 1 small garlic clove
- Zest of 1/2 a lemon
- 2 teaspoons capers (rinsed and drained if salted)
- 7 tablespoons olive oil (or as needed)
- Salt and red pepper flakes, to taste
Step-by-Step Instructions
1. Prepare the Sweet Potatoes and Baking Dish
- Preheat the oven to 375°F (190°C).
- Mix the melted butter and olive oil together.
- Pour 2 tablespoons of this mixture into the bottom of a 2-quart baking dish, ensuring even coverage. (A 9.5-by-12-inch dish works well.)
- Sprinkle the base with a pinch of salt and pepper.
- Peel and thinly slice the sweet potatoes with a sharp knife or mandoline for even, crisp results.
2. Assemble the Roast
- Arrange the sweet potato slices vertically in the prepared dish. Pack the slices snugly in rows or a swirl pattern for maximum crispiness and visual effect.
- Slide thin shallot slices between some of the sweet potato slices for extra aromatic flavor, if desired.
- Brush the tops generously with the remaining butter and olive oil mixture.
- Season well with more salt, black pepper, or red pepper flakes for a gentle kick.
3. Roast, Cover, and Crisp
- Cover the dish tightly with foil and bake for 45 to 50 minutes, until the potatoes are tender but not fully golden.
- Remove the foil and increase oven heat to 450°F (230°C).
- Continue roasting, uncovered, for an additional 10 to 20 minutes until the tops are beautifully crisp and browned.
4. Optional: Prepare the Salsa Verde
While the potatoes finish roasting, make a festive herb sauce for a burst of color and tang.
- Combine parsley, rosemary, thyme, sage, garlic, lemon zest, and capers in a food processor or blender.
- Pulse until finely chopped.
- With the machine running, slowly drizzle in olive oil until the mixture is loose and spoonable.
- Season generously with salt and red pepper flakes to taste.
5. Serve
- Present the roasted sweet potatoes hot, either drizzled with the salsa verde or served with it on the side for guests to add as they like.
- Garnish with fresh herbs for a festive finish.
Tips for Success
- Uniform slices ensure even cooking and crisping—use a mandoline if you have one, but a sharp knife works too.
- A snug fit in the baking dish creates the best texture as the potatoes steam and crisp simultaneously.
- Butter and oil combination improves browning and keeps the potatoes from sticking or drying out.
- Increase oven heat at the end to crisp the potato edges without overcooking the centers.
- Make ahead: Assemble the dish and refrigerate, covered, for several hours before baking. Let come to room temperature before roasting for even cooking.
Variations and Swaps

Serving Suggestions
- Holiday centerpiece: This roast pairs beautifully with turkey, roast beef, or ham.
- Vegetarian main: Serve alongside hearty grain salads or a lentil pilaf for a robust meal.
- Everyday sides: Complement grilled chicken, pork, or a weeknight skillet meal.
- Room temperature friendly: Delicious even after cooling, making it ideal for potlucks and buffets.
Storage and Reheating
- Store leftovers tightly wrapped in the refrigerator for up to 3-4 days.
- Reheat in a hot oven (about 350°F) until warmed through and edges re-crisp.
- Microwaving will soften the crisp edges but is still tasty.
Frequently Asked Questions (FAQs)
Q: Can I make the crispy sweet potato roast in advance?
A: Yes. You can assemble the dish a few hours ahead, refrigerate covered, and bake just before serving. Bring to room temperature first for even roasting.
Q: How do I ensure evenly crispy edges?
A: Slice the sweet potatoes as evenly as possible and arrange them vertically, snugly packed in the dish. Increasing the oven temperature at the end crisps the tops perfectly.
Q: Do I have to use shallots, or can I skip them?
A: Shallots add aromatic depth but are not required. You can substitute with thinly sliced onions, leeks, or omit entirely for a purer sweet potato flavor.
Q: What kind of sweet potatoes work best?
A: Standard orange-fleshed sweet potatoes work best, but you can also use white-fleshed types or garnet yams for color variation and subtle flavor differences.
Q: Is the salsa verde essential?
A: The salsa verde adds brightness and contrast, but the roast is satisfying without it. Consider a simple splash of lemon juice and fresh parsley as an alternative.
