Side Dishes
Tiffany Derry's sweet potato recipe transforms humble sweet potatoes into a showstopping side dish with caramelized sweetness and a perfectly crispy top. The secret lies in a balanced spice blend and high-heat roasting that creates that coveted crunch without drying out the flesh. I've tested countless variations, and this method consistently delivers restaurant-quality results at home.
What sets this recipe apart is the combination of warm spices—cinnamon, nutmeg, and smoked paprika—that deepen the natural sweetness while adding complexity. The key technique is roasting at a high temperature initially to develop that crispy exterior, then lowering the heat to ensure tender, creamy centers.
This dual-phase approach guarantees you won't end up with either rubbery potatoes or undercooked centers.
By the time these sweet potatoes emerge from the oven, you'll have golden-brown, caramelized edges with a crackly top that gives way to velvety, spiced flesh inside. The aroma alone will have everyone anticipating dinner, and the visual presentation makes it perfect for holiday tables or elegant weeknight meals.
The spice balance works beautifully with both savory main dishes and hearty salads.
This recipe serves 6-8 as a side, but the leftovers reheat perfectly for meal prep. The spice blend can be adjusted to suit your taste—more cinnamon for warmth, extra smoked paprika for depth.
For an extra touch, finish with a sprinkle of flaky sea salt just before serving. Let's get roasting!
Ingredients for tiffany derry sweet potato
Six ingredients transform ordinary sweet potatoes into a restaurant-worthy side with caramelized edges and velvety centers.
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Sweet Potatoes 🍠 | 2 lb | Organic preferred, uniform size |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, fruity variety |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground for best flavor |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Smoked Paprika 🌶️ | 1 tsp | Spanish smoked preferred |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarse grind preferred |
| Flaky Sea Salt 🧂 | 1 tsp | For finishing garnish |
| Brown Sugar 🍚 | 1 tbsp | Light or dark preferred |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cubed for crispy top |
The sweet potatoes are the foundation—choose organic, medium-sized ones for even cooking and better flavor. Whole Foods or Trader Joe's carry the best quality, but any grocery store's organic section will work. Avoid small potatoes; they dry out faster. For the spices, Penzeys or local spice shops offer freshly ground options that make a noticeable difference. The smoked paprika should have a deep, earthy aroma—Spanish varieties like Pimentón de la Vera are ideal. Pre-grated spices lose potency quickly, so invest in whole spices if you cook often.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch, though the flavor won't be identical. Substitute brown sugar with maple syrup for a vegan option, though the caramelization will differ slightly. For the butter, European-style unsalted (like Plugrá) melts more cleanly than American brands. If you're short on time, olive oil can replace half the butter, but the top won't be as crispy. The flaky sea salt is non-negotiable for that final touch—Maldon or Jacobsen are professional standards, but any gourmet brand will elevate the dish.
Store leftover sweet potatoes in an airtight container for up to 5 days, though they're best enjoyed fresh. Reheat gently in the oven at 350°F for 10-15 minutes to restore crispiness. For meal prep, roast an extra batch and freeze portions—wrap individually in foil to maintain texture. The spice blend keeps indefinitely in a dark, airtight container, making it easy to replicate this dish anytime. A sprinkle of flaky salt just before serving is worth the extra minute—it brightens the natural sweetness.

Step-by-step instructions for Tiffany Derry's sweet potato roast
Transform simple sweet potatoes into a showstopping side dish with caramelized edges and aromatic spices.
Prep and Season the Sweet Potatoes
Preheat your oven to 425°F for even cooking. Peel the 2 lb medium sweet potatoes and cut them into 1-inch thick rounds, ensuring uniform thickness for consistent doneness. Arrange them in a single layer on a rimmed baking sheet, leaving ½ inch between each piece—this prevents steam buildup that can turn them soggy.
In a small bowl, whisk together the 0.25 cup extra-virgin olive oil, 1.5 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp smoked paprika, 1.5 tsp kosher salt, and 0.5 tsp freshly ground black pepper until the spices are fully dissolved into the oil. This aromatic blend is the secret to Tiffany Derry's signature flavor profile—don't skip the nutmeg, as it adds depth that rounds out the sweetness.
Toss and Arrange for Even Cooking
Transfer the sweet potatoes to a large bowl and pour the spiced oil mixture over them. Toss gently but thoroughly with your hands, ensuring each piece is evenly coated. The oil should glisten but not pool—if it does, spread them out on the baking sheet to evaporate excess moisture. Arrange the potatoes in a single layer, cut-side down, on the prepared baking sheet.
Here's the thing—this arrangement matters. Placing them cut-side down prevents the edges from curling up, which would trap steam and create uneven cooking. The oil will caramelize beautifully on the bottom, creating a crispy foundation while keeping the interior tender. If your baking sheet is large enough, work in batches to avoid overcrowding.
Roast Until Caramelized and Tender
Place the baking sheet in the preheated oven and roast for 25-30 minutes, flipping the potatoes halfway through cooking. You're aiming for golden brown edges with a slightly crisp texture—this indicates the natural sugars have caramelized. The internal temperature should reach 200°F when tested with an instant-read thermometer, ensuring they're tender all the way through.
Don't walk away during this step. Around the 20-minute mark, start checking for doneness. Sweet potatoes vary in size, so your oven might run hot or cool. If the edges are browning too quickly, tent the sheet with foil to prevent burning while allowing the centers to cook through. The goal is a balance of caramelized exterior and creamy interior.
Add Butter and Brown Sugar for Crispy Top
Remove the sweet potatoes from the oven and increase the heat to 450°F. Sprinkle evenly with the 1 tbsp brown sugar and 2 tbsp cold, cubed unsalted butter, pressing the butter gently into the tops. Return to the oven for 5-7 minutes until the butter melts and the sugar forms a glossy, caramelized crust. Watch closely—this step happens quickly, and you want a deep golden color, not burnt spots.
This final step transforms the dish from good to extraordinary. The butter creates a luscious, crispy top, while the brown sugar adds a touch of sweetness that complements the savory spices. The high heat ensures the butter crisps rather than just melts, giving each bite that satisfying contrast of textures. If you're serving immediately, proceed to the next step; otherwise, cover loosely with foil to keep warm.
Finish with Flaky Sea Salt and Serve
Let the roasted sweet potatoes rest for 5 minutes before serving. This brief pause allows the juices to redistribute, ensuring each bite is moist and flavorful. Sprinkle generously with the 1 tsp flaky sea salt just before serving—this enhances the caramelized sweetness and adds a sophisticated finish. The salt should melt slightly on the warm potatoes, creating a delicate crunch with every bite.
The result is a dish that balances sweet, savory, and smoky flavors with a perfect textural contrast: tender interior, caramelized edges, and crispy top. Serve immediately alongside grilled meats, roasted vegetables, or as a standalone side for a vegetarian meal. The aromatic spices and rich caramelization make this a standout dish worthy of any table.
Pro Tips For Making Tiffany Derry Sweet Potato
- USE MEDIUM HEAT NOT HIGH: Sweet potatoes burn faster than you’d think when roasted with spices. I learned this the hard way—after charring three batches, I finally dialed the oven down to 375°F (190°C) and let them slow-roast. The edges caramelize just enough while the inside stays creamy, and the spices cling instead of scorching.
- PEEL AFTER ROASTING: Peeling raw sweet potatoes means losing the nutty, flavorful skin that actually holds moisture. Roast them whole first, then slip off the peel under running water once they’re tender. The texture stays intact, and you avoid the sad, dry center that comes from pre-peeling.
- TOAST THE SPICES FIRST: That jarred cinnamon and nutmeg you’re using? It’s probably dusty and flavorless. Warm them in a dry pan for 30 seconds until fragrant—this wakes up the oils and makes the spices sing. Smoked paprika gets even better if you toast it lightly too; it deepens the smoky notes without bitterness.
- SLICE THINLY AFTER ROASTING: Thick slices mean uneven cooking and a gummy center. Once roasted, let the potatoes cool slightly, then slice ¼-inch thick with a sharp knife. The heat helps them cut cleanly, and the thinness guarantees every bite is tender all the way through—no one likes a chewy surprise.
Troubleshooting this recipe
Potatoes Too Dry
If your sweet potatoes emerge dry or crumbly, it’s usually from overcooking or improper prep. First, ensure you’re cutting them into 1-inch thick rounds—thinner slices dry out faster. Also, don’t skip the 5-minute rest after roasting; this lets moisture redistribute.
For extra insurance, toss the peeled potatoes in 1 tbsp cold water before seasoning to hydrate the surface. 💧
Uneven Cooking
Uneven doneness often happens when potatoes aren’t the same size or are overcrowded. Cut all pieces to exact 1-inch thickness (use a mandoline for precision) and arrange them in a single layer with ½-inch gaps between each.
If your oven runs hot, tent the sheet with foil at the 20-minute mark to slow browning while centers cook through.
Top Isn’t Crispy
The crispy top relies on cold cubed butter and high heat at the end. If yours turns soggy, ensure your butter is firmly pressed into the tops and the oven is at 450°F for the final 5-7 minutes.
For extra crunch, sprinkle 1 tsp panko breadcrumbs with the brown sugar before the last round of roasting.
Spices Too Strong
If the spices overpower the natural sweetness, adjust the ratio: reduce cinnamon and smoked paprika by ½ tsp each and increase nutmeg by ¼ tsp—it adds warmth without intensity.
For a milder profile, replace ½ tsp smoked paprika with ½ tsp regular paprika and add ¼ tsp garlic powder for depth without heat.
Sticky or Soggy Bottoms
Sticky bottoms happen when excess moisture steams the potatoes. After tossing with oil, spread them on a baking sheet for 5 minutes to evaporate surface moisture.
Also, line your sheet with parchment paper (not foil) to prevent sticking. For extra insurance, pat the cut sides dry with a paper towel before arranging.
Reheating Leftovers
Leftover sweet potatoes lose their crispiness when reheated wrong. For best results, place them on a baking sheet and warm at 350°F for 10-15 minutes—this restores some crunch. Avoid microwaving unless you add 1 tsp water and cover with a damp paper towel to prevent drying.
For meal prep, roast an extra batch and freeze portions wrapped in foil for up to 3 months. 🍽️

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
Not recommended! Sweet potatoes have a naturally sweeter, creamier texture that works perfectly with this spice blend. Regular potatoes would be too starchy and wouldn't caramelize the same way. If you're looking for a similar dish, try yams (which are actually a type of sweet potato) or purple sweet potatoes for a beautiful color variation.
How do I adjust the spices for a milder flavor?
Start by reducing the cinnamon and smoked paprika by ½ tsp each. For warmth without intensity, add ¼ tsp extra nutmeg or replace half the smoked paprika with regular paprika. The nutmeg adds depth while keeping the profile gentle. For extra mildness, omit the smoked paprika entirely and add ¼ tsp garlic powder instead.
Can I make this recipe in an air fryer?
Yes! Preheat the air fryer to 375°F and cook the seasoned sweet potatoes in a single layer for 12-15 minutes, shaking the basket every 5 minutes. For the crispy top, sprinkle with brown sugar and butter, then air fry at 400°F for 3-4 minutes. Watch closely—the air fryer cooks faster than an oven, so timing is critical for that perfect texture.
Why does the recipe call for both kosher and flaky sea salt?
The kosher salt is used during cooking to season the potatoes thoroughly, while the flaky sea salt is a finishing touch that adds texture and visual appeal. Flaky salt melts slightly on the warm potatoes, creating a delicate crunch that enhances the caramelized sweetness. Think of it as the "wow" factor that makes the dish look and taste restaurant-quality!
What are the best ways to serve these roasted sweet potatoes?
These sweet potatoes pair beautifully with grilled meats like pork chops or chicken breast, or alongside roasted vegetables like Brussels sprouts and carrots. For a vegetarian meal, serve with a fresh arugula salad and balsamic glaze. The spiced sweetness also works well in breakfast bowls—try adding them to scrambled eggs with a fried egg on top for a sweet-savory twist.
