You know that moment when you bite into something and immediately think “where has this been all my life?”
That’s what happened to me with roasted sweet potatoes.
I’m not talking about those marshmallow-topped casseroles that show up every Thanksgiving. I’m talking about crispy-edged, caramelized sweet potato wedges that are so good, you’ll find yourself making them three times a week.
Here’s the thing about sweet potatoes: they’re stupid easy to work with, they’re packed with nutrients, and they taste like dessert when you cook them right.
The natural sugars caramelize in the oven, the edges get all crispy and golden, and the inside stays creamy and soft.
I started making these on a random Tuesday night when I was tired of my usual dinner rotation. Now they’re a staple in my house, and I’ve converted at least a dozen friends into sweet potato obsessives.
The secret?
High heat, good olive oil, and knowing when to leave them alone. That’s it.
What You’ll Need
The Sweet Potatoes
| Ingredient | Amount | Why It Matters |
|---|---|---|
| Sweet potatoes | 3 large (about 2.5 lbs) | The star of the show |
| Olive oil | 3 tablespoons | Creates that crispy exterior |
| Smoked paprika | 1 teaspoon | Adds depth and smokiness |
| Garlic powder | 1 teaspoon | Because garlic makes everything better |
| Ground cumin | ½ teaspoon | Earthy warmth that balances sweetness |
| Sea salt | ½ teaspoon | Brings out all the flavors |
| Black pepper | ¼ teaspoon | A little kick |
| Cayenne pepper | ¼ teaspoon | Optional, but I always add it 🌶️ |
The Garlic Herb Drizzle (Optional But Amazing)
- 3 tablespoons olive oil
- 3 cloves garlic, minced
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon fresh rosemary, chopped
- Juice of half a lemon
- Pinch of sea salt
Quick tip: The drizzle is totally optional, but it takes these from “really good” to “I need to make these for every dinner party I host.”
Tools You’ll Need
✓ Large baking sheet (or two)
✓ Parchment paper or silicone baking mat
✓ Large mixing bowl
✓ Sharp knife
✓ Cutting board
✓ Small skillet (for the garlic drizzle)
✓ Measuring spoons
Pro Tips
1. Don’t skip the parchment paper
I learned this the hard way after scrubbing caramelized sweet potato off a baking sheet for 20 minutes.
The natural sugars stick like crazy, and parchment makes cleanup about 10 seconds long.
2. Cut them the same size
This sounds obvious, but I used to be lazy about it and end up with some burnt pieces and some undercooked ones.
When they’re all roughly the same thickness (about ½ inch), they cook evenly and you don’t waste any.
3. Give them space
Crowding the pan = steamed sweet potatoes instead of roasted ones.
You want those edges to get crispy and caramelized, which only happens when hot air can circulate around each piece. If you need to use two baking sheets, do it.
4. Flip them halfway through
I know it’s tempting to just set a timer and walk away, but flipping them once ensures you get crispy edges on multiple sides.
It takes 30 seconds and makes a huge difference.
5. Let them cool for a minute before eating
They come out of the oven hot hot.
Like, burn-the-roof-of-your-mouth-for-three-days hot. Give them 2-3 minutes to cool down just enough so you can actually taste them instead of just experiencing pain.
How to Make Crispy Roasted Sweet Potatoes
Step 1: Prep Your Oven and Baking Sheet
Preheat your oven to 425°F (220°C). Line your baking sheet with parchment paper.
This temperature is key. Too low and they’ll be soft but not crispy. Too high and the outside burns before the inside cooks.
Step 2: Cut the Sweet Potatoes
Wash and scrub your sweet potatoes. You can peel them if you want, but I never do. The skin gets crispy and adds texture.
Cut them into wedges or rounds, about ½ inch thick.
Try to keep them relatively uniform so they cook at the same rate.
Step 3: Season Them
Toss the sweet potato pieces into a large bowl.
Drizzle with olive oil and add all your spices: smoked paprika, garlic powder, cumin, salt, pepper, and cayenne if you’re using it.
Mix everything with your hands. It’s messy, but it’s the best way to make sure every piece gets coated evenly.
Step 4: Arrange on the Baking Sheet
Spread the sweet potatoes in a single layer on your prepared baking sheet.
Make sure they’re not touching or overlapping.
This is where a lot of people mess up. If they’re crowded, they’ll steam instead of roast, and you’ll lose that crispy texture.
Step 5: Roast
Pop the baking sheet in the oven and roast for 15 minutes.
After 15 minutes, take the pan out and flip each piece with a spatula. Put them back in for another 15-20 minutes, until the edges are dark and caramelized and a fork slides through easily.
The total time is usually 30-35 minutes, but it can vary based on how thick you cut them.
Step 6: Make the Garlic Herb Drizzle (Optional)
While the sweet potatoes finish roasting, heat 3 tablespoons of olive oil in a small skillet over medium heat.
Add the minced garlic and cook for about 60 seconds, just until fragrant. You don’t want it to brown.
Remove from heat and stir in the fresh herbs, lemon juice, and a pinch of salt.
Step 7: Serve
Transfer the roasted sweet potatoes to a serving plate.
If you made the garlic drizzle, pour it over the top.
They’re perfect as is, but you can also sprinkle some fresh parsley or a squeeze of lime juice over them.
Substitutions and Variations
Spice It Up (Or Down)
| Instead of This | Try This | Flavor Profile |
|---|---|---|
| Paprika + cumin | Curry powder | Warm, Indian-inspired |
| Paprika + cumin | Za’atar | Middle Eastern, herby |
| Paprika + cumin | Cinnamon + brown sugar | Sweet and dessert-like |
| Paprika + cumin | Italian seasoning | Mediterranean vibes |
Oil Options
Olive oil is my go-to, but these work great too:
- Coconut oil (adds a subtle sweetness)
- Avocado oil (higher smoke point, neutral flavor)
- Melted butter (extra rich, but not as crispy)
Make It a Meal
Want to turn this into a complete dinner? Add these to the pan:
Protein: Chickpeas (last 20 min of cooking)
Veggies: Red onion wedges, bell pepper strips
Greens: Toss arugula on top when serving
Sweet and Spicy Version 🔥
Add 1 tablespoon maple syrup to the oil before tossing. The combination of sweet and spicy is chef’s kiss.
Herb Variations
- Instead of rosemary: Try thyme or sage
- Instead of parsley: Fresh cilantro + lime juice
- No fresh herbs? Use 1 teaspoon dried Italian seasoning
Make-Ahead Tips
| What | When | How to Store |
|---|---|---|
| Cut sweet potatoes | Up to 24 hours ahead | In cold water in the fridge (prevents browning) |
| Spice mix | Weeks ahead | In a small jar or container |
| Cooked potatoes | Not recommended | They lose crispiness |
Pro move: If you’re meal prepping, cut all your sweet potatoes on Sunday, keep them in water, and you’ll have 5-minute prep all week long.
Leftovers and Storage
In the fridge: Store in an airtight container for up to 4 days.
To reheat: Spread on a baking sheet and pop in a 400°F oven for 8-10 minutes. The microwave will make them soggy, so don’t do it unless you’re desperate.
Eat them cold: They’re actually really good in salads or grain bowls straight from the fridge.
Freeze them: Freeze in a single layer on a baking sheet first, then transfer to a freezer bag once solid. They’ll keep for about 3 months. Reheat from frozen at 400°F for 15-20 minutes.
Leftover hack: Chop them up and add to breakfast burritos or scrambled eggs. Game changer.

FAQ
Why are my sweet potatoes soggy?
You probably crowded the pan or didn’t use enough heat.
Make sure they’re in a single layer with space between each piece, and your oven is at least 425°F.
Can I use purple or white sweet potatoes?
Yep! The cooking time and method are the same.
Purple sweet potatoes have a slightly nuttier flavor and white ones are a bit less sweet, but they all work great.
Do I have to peel them?
Nope. I never do.
The skin crisps up nicely and has extra fiber and nutrients. Just scrub them well before cutting.
Can I make these in an air fryer?
Yes! Cook at 400°F for 15-20 minutes, shaking the basket halfway through.
They get super crispy in the air fryer.
How do I know when they’re done?
The edges should be dark and caramelized, and a fork should slide through the thickest part easily.
If you like them extra crispy, give them an extra 5 minutes.
Can I use this method for regular potatoes?
You can, but you’ll need to adjust the cooking time.
Regular potatoes take about 10 minutes longer because they have less sugar and more starch.
What’s the difference between sweet potatoes and yams?
In the US, what we call yams are almost always just orange sweet potatoes.
True yams are a completely different vegetable that’s common in African and Caribbean cooking. They’re starchier and less sweet.
Why do mine burn on the outside but stay hard inside?
Your oven temp is too high, or you cut them too thick.
Stick to ½ inch thickness and 425°F max.
Cooking Time Cheat Sheet
| Cut Size | Oven Temp | Time | Flip At |
|---|---|---|---|
| ½ inch wedges | 425°F | 30-35 min | 15 min |
| ¾ inch wedges | 425°F | 40-45 min | 20 min |
| 1 inch cubes | 425°F | 25-30 min | 12 min |
| Whole (small) | 400°F | 45-60 min | No flip |
Wrapping Up
Look, I’m not going to tell you these will change your life or that you’ll never eat regular potatoes again.
But I will say that once you nail this technique, you’ll have a go-to side dish that works for basically any meal, tastes amazing, and takes about 5 minutes of actual work.
I make these at least once a week, and I’m still not tired of them.
Try them out and let me know what you think in the comments. Do you add any different spices? Serve them with anything unexpected? I’m always looking for new ways to mix things up. 💬
