Ingredients for sweet potato appetizer
Sweet potatoes, crispy celery, and cheesy dip—simple ingredients for a showstopper appetizer.
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Sweet Potatoes 🍠 | 3 whole | Organic preferred, skin-on for texture |
| Celery Stalks 🥬 | 8 whole | Fresh, crisp, for crowns |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, aged for best flavor |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Mayonnaise 🥫 | ¼ cup | Duck or regular preferred |
| Garlic Cloves 🧄 | 2 cloves | Minced for dip flavor |
| Dijon Mustard 🍯 | 1 tbsp | For tangy depth |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for roasting |
| Smoked Paprika 🌶️ | ½ tsp | For garnish and depth |

Sweet potatoes are the star here—organic if possible, but any medium-sized ones work. Look for firm, smooth skins at Whole Foods or your local market—they roast best. The celery should be crisp and vibrant, not rubbery or yellowing. I grab a bunch and keep some for soups later. For the cheddar, sharp aged is ideal—it melts beautifully and adds depth. Pre-shredded gets clumpy, so grate your own if you can. The heavy cream and sour cream? Full-fat versions make this dip truly velvety, so don't skimp there.
No sharp cheddar? Pepper jack or Gouda work in a pinch, though the flavor won't be identical. Running out of celery? Green onions or radish slices make decent crowns—just slice them thinner. The dip can be made ahead and chilled for up to 3 days, while the sweet potatoes are best roasted fresh. For extra crunch on the crowns, dip the celery in beaten egg before toasting. The smoked paprika? Trust me on this—it adds a subtle smokiness that ties everything together. And if you're feeling fancy, swap regular mayo for avocado mayo.
Roasted sweet potatoes keep well in the fridge for 4 days if stored in an airtight container, but they're best served warm. The dip? It actually tastes better the next day as the flavors meld. Portion the dip into small containers so you can grab it straight from the fridge and serve it cold or at room temperature. For parties, I like to make a double batch of dip and keep it in a slow cooker on warm setting—no one goes home hungry. The celery crowns stay crisp for about 1 hour after baking, so assemble them last minute for maximum crunch.

Step-by-step instructions for crispy celery crown over creamy cheddar dip
Here's how to create perfectly crispy sweet potato crowns and a velvety cheddar dip that'll have everyone reaching for seconds.
Roast Sweet Potatoes Until Caramelized
Preheat your oven to 400°F and line two baking sheets with parchment paper. Cut the 3 whole medium sweet potatoes lengthwise into ½-inch thick slices, leaving the skin intact. Arrange them in a single layer on the prepared sheets, brushing both sides lightly with 1 tablespoon olive oil.
Sprinkle with ½ teaspoon salt and ¼ teaspoon black pepper, then roast for 20-25 minutes until the edges are deep golden brown and the centers yield slightly when pressed with a fork. The sweet potatoes should be tender but still hold their shape—this ensures they stay crispy when assembled. For extra flavor, I like to sprinkle with ¼ teaspoon smoked paprika during the last 5 minutes of roasting.
Prepare Celery Crowns for Crispy Perfection
While the sweet potatoes roast, wash and dry the 8 whole celery stalks thoroughly. Using a sharp chef's knife, carefully slice off the leafy tops (save for garnish if desired) and trim the bottoms to create flat surfaces. Cut each stalk lengthwise into ¼-inch thick strips, creating a crown shape.
Arrange the celery crowns on a separate baking sheet lined with parchment paper. Drizzle lightly with the remaining 1 tablespoon olive oil and sprinkle with ¼ teaspoon salt. Roast at 400°F for 10-12 minutes until the edges are golden brown and slightly crispy. Watch closely—they cook quickly and burn easily. For extra flavor, toss them with ¼ teaspoon smoked paprika before roasting.
Assemble the Creamy Cheddar Dip
In a medium saucepan, combine the 1.5 cups sharp cheddar cheese, 0.5 cup heavy cream, 0.25 cup mayonnaise, 2 minced garlic cloves, 1 tablespoon Dijon mustard, 0.5 teaspoon salt, and 0.25 teaspoon black pepper. Warm over medium-low heat, stirring constantly with a silicone spatula, until the cheese melts completely and the mixture is smooth.
Remove from heat and stir in the 0.25 cup sour cream until fully incorporated. The dip should be thick and creamy—if it's too thin, warm it for another minute to thicken. For extra flavor, I like to add a pinch more salt and adjust the seasoning to taste. Transfer to a serving bowl and cover with plastic wrap, pressing it directly on the surface to prevent a skin from forming.
Build and Serve the Appetizer
To assemble, place a roasted sweet potato slice on each serving plate. Top with a crispy celery crown, arranging it like a crown on top of the sweet potato. Spoon the cheddar dip generously around the base, creating a pool for dipping. Garnish with chopped 0.25 cup fresh parsley and a sprinkle of smoked paprika for color and extra flavor.
Serve immediately while everything is warm and crispy. The contrast of the crispy celery crowns with the creamy, warm cheddar dip creates a perfect balance of textures and flavors. For extra presentation, I like to arrange them on a large platter and serve with additional dip in the center for sharing. This appetizer is perfect for parties, game days, or any gathering where you want to impress your guests with minimal effort and maximum flavor.
Pro Tips For Making Sweet Potato Appetizer
- CUT POTATOES UNIFORM: Peel and dice those sweet potatoes into even ½-inch cubes—no bigger, no smaller. I learned this the hard way when half my batch stayed raw inside while the edges turned to mush.
- SALT CELERY BEFORE DICING: Toss celery stalks in a pinch of salt and let them sit for 10 minutes before chopping. This draws out moisture so they don’t turn to soup when mixed with the creamy filling.
- DON’T OVERMIX THE FILLING: Stir the heavy cream, mayo, and cheddar just until combined—lumpy is fine. Overworking it turns the filling greasy, and trust me, you don’t want that in an appetizer.
- BAKE AT 375°F, NOT HIGHER: Sweet potatoes brown faster than they cook through at 400°F. Stick to 375°F and check at 20 minutes—this guarantees tender centers every time.
Make-ahead tips for leftovers
Dip Prep Ahead
The cheddar dip is the star of this appetizer, and it actually tastes better when made a day in advance. Whip up the dip the night before and store it in an airtight container in the fridge.
When ready to serve, simply warm it gently in a saucepan over low heat for 5-7 minutes, stirring until smooth. This allows the flavors to meld beautifully, making the dip extra creamy and rich. 🥛
Sweet Potato Storage
Roasted sweet potatoes keep well in the fridge for up to 4 days if stored properly. After roasting, let them cool completely, then transfer to an airtight container or sealed plastic bag. To reheat, pop them in the oven at 350°F for 10-15 minutes until warmed through.
For extra crispiness, broil for 2-3 minutes at the end. This ensures they stay tender inside with crispy edges, just like fresh.
Celery Crown Assembly
Celery crowns are best assembled fresh, but you can prep the celery strips ahead of time. After roasting, let them cool completely, then store in an airtight container with a paper towel to absorb moisture.
Reheat in the oven at 375°F for 5-7 minutes before assembling on the sweet potatoes. This keeps them crispy and prevents sogginess. Trust me, this step saves time and keeps your appetizer looking fresh. 🥬
Make-Ahead Party Hack
For large gatherings, make the dip and roast the sweet potatoes 2 days ahead. Store them separately in airtight containers in the fridge. On the day of your event, simply reheat the sweet potatoes and celery crowns, then assemble the appetizer.
This way, you can spend time with your guests instead of stressing in the kitchen. The dip can even be reheated in a slow cooker on low heat for a crowd-friendly serving option.
Freezer-Friendly Dip
If you're prepping for a future party, the cheddar dip freezes beautifully. Portion it into quart-sized freezer bags, removing as much air as possible to prevent freezer burn. Thaw overnight in the fridge, then reheat gently.
The texture might be slightly grainier after freezing, but the flavor remains rich and delicious. This is a great way to have a ready-to-go appetizer on hand for last-minute gatherings. ❄️
Last-Minute Garnish
Fresh parsley and smoked paprika are the perfect finishing touches, but they can be added just before serving. Chop the parsley and measure out the smoked paprika the night before, storing them in small containers.
This keeps your prep organized and ensures everything looks fresh and vibrant when you're ready to serve. A little garnish goes a long way in making your appetizer look restaurant-worthy. 🌿
Nutrition facts
Frequently asked questions
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 add natural sweetness and a creamy texture that pairs perfectly with the cheddar dip. For the best results, stick with sweet potatoes—but if you're in a pinch, Yukon Golds roasted at 425°F for 15-20 minutes will work in a pinch.
How do I make this appetizer vegetarian?
This recipe is already vegetarian! The cheddar dip and roasted sweet potatoes are completely plant-based. For extra protein, consider adding a side of hummus or vegan sour cream to the dip. The celery crowns add freshness without any animal products.
Why did my celery crowns turn soggy? Soggy celery crowns usually happen from one of two things: overcrowding on the baking sheet or not roasting long enough.
Can I make this gluten-free?
This recipe is naturally gluten-free as long as you use certified gluten-free smoked paprika and check your cheddar cheese label. The celery crowns and sweet potatoes are both gluten-free ingredients. Just be sure to avoid cross-contamination with gluten-containing utensils or surfaces.
What's the best way to reheat leftovers?
For the best results, reheat roasted sweet potatoes in the oven at 350°F for 10-15 minutes until warmed through. The celery crowns can be reheated separately at 375°F for 5 minutes to keep them crispy. The dip reheats beautifully in the microwave for 30-45 seconds or gently in a saucepan over low heat.
