Ingredients for sweet potato apple cinnamon
Sweet potatoes, apples, and celery transform into a spiced roast with crispy topping—simple ingredients for autumn flavors.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Medium size, peeled and cubed |
| Apples 🍎 | 2 medium | Honeycrisp or Fuji, peeled and cubed |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For tossing vegetables |
| Brown Sugar 🍚 | ¼ cup | Packed light brown sugar |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground for best flavor |
| Salt 🧂 | 1 tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked black pepper |
| Celery Stalks 🥬 | 2 whole | Thinly sliced into crowns |
| Maple Syrup 🍯 | 2 tbsp | Pure grade B for richness |
| Garlic Cloves 🧄 | 2 cloves | Minced for celery crowns |
| Fresh Rosemary 🌿 | ½ tsp | Chopped, for celery crowns |
| Nutmeg 🌶️ | ¼ tsp | Freshly grated for warmth |
The sweet potatoes and apples are the heart of this dish—Honeycrisp or Fuji apples hold their shape best when roasted, and organic sweet potatoes from Whole Foods or your local market have the best texture. Look for sweet potatoes that are firm and heavy for their size. The celery? Organic celery crowns from Trader Joe's are perfect for this—thinly sliced, they crisp up beautifully while keeping their structure. If you can't find organic, regular celery works fine, just give it a good rinse before slicing.
No Honeycrisp apples? Gala or Pink Lady work just as well—they're sweeter and hold up nicely. Running low on maple syrup? Agave nectar or brown sugar glaze gives similar sweetness, though maple adds that unmistakable autumnal depth. Fresh rosemary is ideal, but dried rosemary at half the amount works in a pinch. The cinnamon and nutmeg are non-negotiable for that warm spice profile—Penzeys Spices has the best quality if you're willing to splurge, but the grocery store stuff is fine too. Just make sure it's freshly ground if possible.
This dish reheats beautifully—350°F for 10-15 minutes brings it back to life. Store leftovers in an airtight container for up to 5 days in the fridge, though honestly, it's best enjoyed fresh. For make-ahead prep, roast the sweet potatoes and apples first, then add the celery crowns just before serving so they stay crisp. The flavors actually improve overnight as everything melds together—perfect for meal prep.

Step-by-step instructions for sweet potato apple cinnamon roast
A warm, spiced roast that balances sweet and savory perfectly—crispy on the outside, tender within.
Prep the Sweet Potatoes and Apples
Start by peeling and cubing the 2 lbs sweet potatoes into even 1-inch pieces. Toss them in a large bowl with 0.25 cup extra-virgin olive oil, 2 tsp ground cinnamon, 1 tsp salt, and 0.5 tsp black pepper. Use your hands to coat each piece thoroughly—this ensures even seasoning and crispy edges.
In a separate bowl, peel and cube the 2 medium apples (Honeycrisp or Fuji work best). Toss them with 0.25 cup brown sugar and 0.25 tsp nutmeg—this sweet-spiced mix will caramelize beautifully during roasting. Keep the apples separate from the sweet potatoes for now.
Roast the Sweet Potatoes Until Tender
Preheat your oven to 400°F. Spread the seasoned sweet potatoes in a single layer on a parchment-lined baking sheet, leaving space between pieces for airflow. Roast for 25-30 minutes, stirring halfway, until they're fork-tender but still holding their shape. The edges should be golden brown—this is your cue they're ready.
While they roast, prepare the celery crowns. Thinly slice the 2 whole celery stalks into 1-inch rounds (crowns). In a small bowl, toss them with 2 tbsp maple syrup, 2 minced garlic cloves, and 0.5 tsp chopped fresh rosemary. Let this sit while the sweet potatoes cook—this marinade will add depth to the crispy topping.
Add Apples and Celery Crowns for Caramelization
After the sweet potatoes are tender, remove the baking sheet from the oven. Scatter the apple cubes evenly over the sweet potatoes, then arrange the celery crowns in a single layer on top. Return to the oven and roast for another 15-20 minutes until the apples soften and the celery crowns turn deep golden brown and crispy.
Here's the thing—don't overcrowd the pan. If your baking sheet is full, transfer the apples and celery to a second sheet in the last 10 minutes of roasting. The goal is crispy celery crowns and caramelized apples, not soggy vegetables.
Broil for Extra Crispiness (Optional but Recommended)
For maximum crispiness, switch your oven to broil and place the roasted vegetables 3-4 inches from the heat source. Broil for 2-3 minutes, watching closely to avoid burning. You'll see the celery crowns darken slightly and the apples develop a glossy sheen—this is the moment they transform from good to extraordinary.
Real talk: This step makes all the difference. The broiler intensifies the caramelization and adds that restaurant-quality texture. If your oven runs hot, broil for just 1-2 minutes—you want crispy, not burnt.
Rest and Serve Warm
Remove from the oven and let the roast rest for 5 minutes before serving. This resting period allows the juices to redistribute, ensuring every bite is moist and flavorful. The celery crowns will stay crispy, the apples will be tender, and the sweet potatoes will hold their shape.
Serve immediately while warm. The contrast of crispy celery crowns, caramelized apples, and tender sweet potatoes creates a perfect balance of textures and flavors. Pair with a dollop of Greek yogurt or a sprinkle of toasted pecans for extra richness.
Pro Tips For Making Sweet Potato Apple Cinnamon
- CUT APPLES IN EVEN SLICES: Thin, consistent slices caramelize faster and soak up the cinnamon-sugar better. I used to eyeball it and end up with some chunks that stayed undercooked—now I aim for ¼-inch thickness with a mandoline. (Yes, it’s worth the extra 30 seconds.)
- ROAST SWEET POTATOES FIRST: Start them at 400°F (200°C) for 20 minutes before adding apples—this jumpstarts the caramelization and prevents soggy potatoes. After burning one batch where I mixed everything in raw, I never went back.
- USE COLD APPLES: Pull apples straight from the fridge for tighter flesh that holds its shape longer. Warm apples turn to mush faster, especially when tossed with sweet potatoes. (Pro tip: Pat them dry first—moisture is the enemy of crisp edges.)
- STIR HALFWAY THROUGH: After 15 minutes, give the pan a quick stir to redistribute the apples and prevent sticking. I learned this the hard way when my first batch stuck like glue, and now I set a timer so I don’t forget. (A wooden spoon helps—metal can shred the sweet potatoes.)
Make-ahead tips for leftovers
Prep Ahead Strategy
Roast the sweet potatoes and apples 24 hours ahead—they actually taste better after resting as the flavors meld. Store them in an airtight container in the fridge. When ready to serve, simply reheat at 350°F for 15 minutes and top with freshly crisped celery crowns.
This two-stage approach saves time while keeping the dish restaurant-quality. 💡
Celery Crown Timing
Celery crowns lose crispness quickly, so add them 30 minutes before serving if prepping ahead. Toss pre-sliced crowns with 2 tbsp maple syrup and ½ tsp rosemary, then roast at 400°F for 15 minutes until golden.
Keep them separate until the final step to maintain crunch. Trust me, this makes all the difference!
Freezer-Friendly Base
For long-term storage, roast the sweet potatoes and apples fully, then freeze them in a single layer on a tray before transferring to an airtight freezer bag.
Thaw overnight in the fridge, then reheat with fresh celery crowns. The texture holds up surprisingly well—just add 1 tbsp water when reheating to prevent drying. ❄️
Batch Cooking Tips
Double the recipe and store components separately: sweet potatoes/apples in one container, celery crown marinade in another. When ready to serve, toss the celery in its marinade and roast alongside the reheated base.
This method works perfectly for family gatherings or meal prep Sundays. The flavors stay vibrant for up to 5 days in the fridge.
Garnish Prep
Toast ½ cup pecans in a dry pan over medium heat for 3-4 minutes and store in an airtight container at room temperature. Sprinkle over the finished dish just before serving for added crunch and richness.
Alternatively, keep fresh parsley chopped and ready to garnish—it adds a bright contrast to the warm spices. 🌟

Frequently asked questions
Can I make this recipe without an oven?
For a stovetop version, use a large skillet with 1/4 cup olive oil and cook the sweet potatoes and apples over medium-low heat for 20-25 minutes, stirring occasionally. Add the celery crowns in the last 5 minutes to keep them crispy. Cover the skillet for the first 15 minutes to help soften the vegetables faster. The flavors will be slightly different but still delicious.
What's the best apple variety for this recipe?
Honeycrisp or Fuji apples work best—they hold their shape when roasted and have a perfect balance of sweetness and tartness. If you can't find them, Gala or Pink Lady are great alternatives. Avoid overly soft varieties like McIntosh, as they'll turn mushy during roasting. The key is an apple that's firm enough to caramelize but sweet enough to complement the cinnamon.
How can I make this dish vegan?
Swap the maple syrup for agave nectar or coconut sugar, and use vegan butter or olive oil instead of regular butter. For the celery crowns, replace the maple syrup with 1 tbsp agave + 1 tbsp apple cider vinegar to mimic the caramelization. The cinnamon, nutmeg, and other spices are naturally vegan, so no other changes are needed. The texture will be just as satisfying!
Why did my celery crowns turn soggy?
Celery crowns lose crispness when exposed to moisture or overcrowding. To fix this, ensure they're arranged in a single layer on the baking sheet with space between each piece. If your pan is full, transfer them to a second sheet in the last 10 minutes of roasting. Also, avoid adding them too early—they should go on top of the sweet potatoes and apples only after the potatoes are already tender.
Can I use regular potatoes instead of sweet potatoes?
While you can use regular potatoes, the flavor and texture won't be the same. Sweet potatoes bring natural sweetness and a creamier texture that pairs perfectly with the apples and cinnamon. If you're set on using regular potatoes, increase the cinnamon to 3 tsp and add 1/4 tsp ground allspice to enhance the spiced flavor. The dish will still be tasty but will lack that signature sweet potato depth.
