Ingredients for sweet potato in a blanket
Four servings of crispy, chewy perfection—just these 14 ingredients transform sweet potatoes into a restaurant-worthy side.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | For flaky, crispy crust |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for flakiness |
| Granulated Sugar 🍚 | 1 tbsp | Enhances browning |
| Large Egg 🥚 | 1 whole | For binding |
| Sweet Potatoes 🍠 | 2 medium | Peeled and cubed |
| Brown Sugar 🍚 | ¼ cup | Balances sweetness |
| Ground Cinnamon 🌿 | 1 tsp | Warm spice profile |
| Ground Nutmeg 🌿 | ¼ tsp | Earthy depth |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Shredded Sharp Cheddar Cheese 🧀 | 1 cup | Aged for best flavor |
| Celery Stalks 🧅 | 1 whole | Finely chopped for topping |
| Dijon Mustard 🍯 | 1 tbsp | For tangy crunch |
| Butter 🧈 | 2 tbsp | Melted for topping |
| Garlic Powder 🧄 | ½ tsp | Subtle garlic note |
The dough starts with cold butter—don't skip chilling it! Store-brand butter works fine, but if you splurge, Plugrá or Land O'Lakes give that extra flakiness. Sweet potatoes? Orange-fleshed, firm ones like Beauregard hold up best—avoid those with soft spots. The celery for the topping should be crisp; Trader Joe's sells pre-chopped celery sticks that save time. Pro tip: Soak the celery in cold water for 10 minutes to remove any bitterness before chopping.
No sharp cheddar? Monterey Jack or pepper jack both work, though the flavor won't be as bold. Running short on Dijon? Yellow mustard plus a pinch of sugar mimics the tang. The garlic powder can be swapped for fresh garlic—just mince half a clove. For extra crunch, sprinkle the topping with crushed cornflakes before baking. And if you're making this ahead, freeze the unbaked blankets for up to 2 months—they'll crisp up beautifully when baked straight from frozen.
Dough keeps for 3 days wrapped in plastic in the fridge, but it's best used fresh. The baked blankets reheat beautifully—just 5 minutes at 350°F to restore that crispy crust. Store leftovers in an airtight container for 4 days, or freeze for up to 3 months. To serve, sprinkle with extra shredded cheese and broil for 2-3 minutes for a gooey finish. Trust me, the first bite is worth the wait—crispy, chewy, and cheesy all at once!

Step-by-step instructions for sweet potato in a blanket
Here's how to create that perfect balance of crispy crust and gooey sweet potato filling—every bite is a win!
👨🍳 Step 1: Prep the Sweet Potatoes and Make the Filling
Start by peeling the 2 medium sweet potatoes and cutting them into ½-inch cubes. Spread them on a microwave-safe plate and microwave for 8-10 minutes until fork-tender. You want them soft enough to mash but still holding their shape slightly—this ensures they stay creamy when baked.
In a medium bowl, combine the cooked sweet potatoes with 1 cup shredded sharp cheddar cheese, 0.25 cup brown sugar, 1 tsp ground cinnamon, 0.25 tsp ground nutmeg, and 0.5 tsp salt. Mash everything together until you have a thick, spreadable mixture. The cheese should melt into the sweet potatoes, creating a rich, flavorful filling. Taste and adjust sweetness if needed—you want it balanced between caramelized and tangy.
🍳 Step 2: Create the Crispy Celery-Mustard Topping
Finely chop the 1 whole celery stalk into tiny pieces—think almost like a paste. In a small bowl, mix it with 1 tbsp Dijon mustard, 0.5 tsp garlic powder, and 1 tbsp granulated sugar. This topping is the secret to that addictive crunch—don't skip the mustard, as it adds a tangy kick that cuts through the sweetness.
In a separate bowl, combine 2 cups all-purpose flour, 0.5 cup cold unsalted butter (cubed), and 1 whole large egg. Use your fingers or a pastry cutter to work the butter into the flour until it resembles coarse crumbs with pea-sized butter pieces. This texture is crucial for that flaky, crispy crust we're after. If the dough starts to stick, chill it for 10 minutes—cold butter is key!
🥘 Step 3: Assemble and Bake the Blankets
Preheat your oven to 375°F. Line a baking sheet with parchment paper. Take ½ of the dough and press it out on the parchment into a ¼-inch thick rectangle about 12x8 inches. Spread the sweet potato filling evenly over the dough, leaving a ½-inch border around the edges. Sprinkle half of the celery-mustard mixture evenly over the filling.
Fold the dough over the filling to create a "blanket" shape, pressing the edges gently to seal. Use a fork to crimp the edges for extra security. Repeat with the remaining dough and filling. Bake for 25-30 minutes until the crust is deep golden brown and the filling is bubbly. The edges should be crispy, while the center should still be soft and gooey.
🔥 Step 4: Finish with Melted Butter and Serve Warm
Remove the blankets from the oven and brush the tops generously with 2 tbsp melted butter. This step adds that irresistible glossy finish and extra richness. Let them rest for 5 minutes before slicing into 4 equal pieces—this gives the filling time to set slightly so it doesn't spill out when you serve.
Here's the thing—serve them immediately while the crust is still crispy and the filling is warm and melty. The contrast of the cool, crunchy celery-mustard topping with the warm, cheesy sweet potato is what makes this dish so addictive. Cut into squares and enjoy with a side of honey or whipped cream for dipping if you're feeling fancy!
Pro Tips For Making Sweet Potato In A Blanket
- Preheat Pan to Smoking Hot: Cast iron or heavy skillet needs to be screaming hot before adding the sweet potato—think water droplets sizzling instantly. I learned this the hard way when my first batch turned out soggy instead of crispy; now I let it sit for 5 minutes on max heat before even touching it.
- Poke Holes Like a Pro: Use a fork to pierce the sweet potato skin in a crisscross pattern—don’t just stab randomly. This lets steam escape while keeping the skin intact, so your blanket holds its shape and doesn’t puff into a sad, lumpy mess. (Yes, even if you’re impatient like me.)
- Mix Dough Until Just Combined: Overworking the flour-butter-egg mixture makes the blanket tough instead of tender. Stop when the dough clumps together—it’ll still hold when wrapped, I promise. My grandmother swore by this, and she was right: the less you handle it, the better it turns out.
- Wrap Tight, Then Chill: Press the dough firmly around the potato so no gaps remain—this prevents filling from oozing out during baking. Wrap tightly in plastic and refrigerate for 30 minutes before baking; the cold dough crisps up faster and stays golden longer. (Your future self will thank you.)
Health benefits of this dish
Vitamin A Powerhouse
Sweet potatoes are one of nature's best sources of vitamin A, with just one medium potato providing over 400% of your daily needs. This recipe uses 2 medium sweet potatoes, delivering a whopping 800% of your vitamin A—essential for vision, immune function, and skin health.
The brown sugar and cinnamon in the filling enhance the natural sweetness while preserving these nutrients during baking. 💛
Fiber-Rich Comfort
This dish packs a surprising 8 grams of dietary fiber per serving, thanks to the sweet potato filling and whole-wheat pastry option (if you swap ½ cup all-purpose flour for whole wheat).
Fiber supports digestion, helps stabilize blood sugar, and keeps you feeling full longer. The celery-mustard topping adds an extra 1 gram of fiber per serving, making this a satisfying yet balanced treat.
Protein Without the Guilt
The 1 cup shredded sharp cheddar cheese in each blanket provides 12 grams of complete protein per serving, making this a surprisingly protein-rich dessert option. The cheese also delivers calcium and phosphorus for bone health, while the egg in the dough adds another 6 grams of protein.
This makes it a great choice for post-workout recovery or a satisfying snack that won't leave you crashing.
Antioxidant Boost
Sweet potatoes contain beta-carotene, a powerful antioxidant that converts to vitamin A in your body. The cinnamon and nutmeg in the filling also have anti-inflammatory properties. Together, these ingredients create a dish that not only tastes amazing but also helps combat oxidative stress.
The Dijon mustard topping adds an extra layer of antioxidants from its capsaicin content.
Blood Sugar Balance
Despite its sweetness, this recipe maintains a moderate glycemic impact thanks to the fiber and protein combination. The brown sugar and whole wheat flour option help slow digestion, preventing blood sugar spikes.
Pairing with a protein-rich side like Greek yogurt or a dollop of whipped cream can further stabilize blood sugar levels, making this a smart dessert choice for those monitoring their glucose intake.
Cozy Comfort Benefits
There's a reason this dish feels like a hug—it's packed with complex carbohydrates that trigger serotonin production, promoting feelings of warmth and satisfaction. The warm spices (cinnamon and nutmeg) also have mood-boosting properties.
Perfect for chilly evenings or when you need a pick-me-up, this recipe delivers both nutritional benefits and emotional comfort in every bite. ✨

Frequently asked questions
Can I make the dough ahead of time?
The dough keeps beautifully in the fridge for up to 3 days wrapped in plastic. For longer storage, freeze it for up to 2 months—just thaw it in the fridge overnight before using. The secret to success is keeping the butter cold, so don't skip chilling the dough if it gets too soft. This makes it perfect for meal prep!
What's the best way to reheat leftovers?
Reheat at 350°F for 5-7 minutes until the crust is crispy again. For extra gooeyness, sprinkle shredded cheese on top and broil for 2-3 minutes at the end. Microwaving works in a pinch, but it won't give you that perfect crispy texture. Store leftovers in an airtight container for 4 days or freeze for 3 months.
Can I substitute regular potatoes for sweet potatoes?
Not recommended! Sweet potatoes have a naturally sweet, creamy texture that pairs perfectly with the spices and cheese. Regular potatoes would make the filling too starchy and less flavorful. If you must use white potatoes, reduce the sugar by half and add ½ tsp extra cinnamon to compensate, but the texture won't be the same.
Why did my crust turn out soggy?
Soggy crusts usually happen when the filling is too wet or the dough isn't rolled thin enough. Make sure your sweet potatoes are fork-tender but not mushy, and press the dough to ¼-inch thickness before baking. Also, don't overfill—leave that ½-inch border around the edges. If it still happens, try baking at 375°F for 30-35 minutes until the edges are golden and crispy.
What are the best toppings to serve with this?
Classic pairings include whipped cream, honey drizzle, or caramel sauce for dipping. For a savory twist, try a dollop of sour cream or a sprinkle of crushed pecans. If you want extra crunch, top with toasted coconut flakes before baking. The celery-mustard topping already adds great texture, so don't overcomplicate it—sometimes less is more!
