If there’s one recipe that has graced my dinner table more times than I can count this year, it’s these Crispy Baked Sweet Potato Rounds with Avocado Cream. The first time I served them, my usually salad-averse nephew asked for seconds—of a vegetable dish. Since then, they’ve become my go-to for everything from casual weeknight suppers to holiday potlucks where I know at least half the guests are vegetarian.
I love how the natural sweetness of the potatoes caramelizes in the oven, creating those irresistible crispy edges, while the avocado cream delivers a cool, tangy counterpoint that keeps everyone dipping until the very last round is gone. They’re gluten-free, dairy-free, and—if you skip the honey in the cream—completely vegan. In short, they check every box and still feel indulgent.
Why This Recipe Works
- Maximum crisp: A light cornstarch toss + high-heat oven equals shatteringly crisp edges without deep-frying.
- Speedy shortcut: ⅛-inch rounds bake in just 18 minutes—no par-boiling required.
- Make-ahead friendly: Roast potatoes up to two days early; reheat at 425 °F for 5 minutes.
- Customizable: Swap chili powder for smoked paprika, or turn the avocado cream into herbed ranch with dill and parsley.
- Balanced nutrition: Complex carbs + healthy fats + 7 g plant protein per serving = satisfied appetites.
- Kid-approved: Mild sweetness and finger-food shape win over picky eaters every time.
Ingredients You'll Need
Sweet potatoes are the star, so start with firm, unblemished ones—ideally the deeper-orange Garnet or Jewel varieties. Their higher moisture and sugar content encourage browning and that candy-like edge we’re chasing. Look for medium-sized tubers about 2 inches in diameter; they yield the most uniform rounds.
For the rounds:
- Sweet potatoes: 2 lb (about 3 medium). Avoid the pale Hannah variety—they’re too dry.
- Cornstarch: 2 Tbsp. Arrowroot or potato starch work, but cornstarch gives the airiest crust.
- Olive oil: 3 Tbsp extra-virgin. Avocado oil is a fine high-heat substitute.
- Smoked paprika: 1 tsp. Adds subtle campfire flavor without heat.
- Sea salt & black pepper: ¾ tsp and ¼ tsp respectively. Use freshly cracked pepper for the best bite.
For the avocado cream:
- Ripe avocados: 2 medium. Flesh should yield gently to pressure but not feel mushy.
- Lime: 1 large, zested and juiced (about 2 Tbsp juice). Lemon works, but lime’s floral acidity pairs better with sweet potato.
- Garlic: 1 small clove, micro-planed. Omit if serving to true garlic-phobes.
- Plain coconut yogurt: ¼ cup. Unsweetened almond or cashew yogurt keep it dairy-free; Greek yogurt is fine if dairy isn’t a concern.
- Honey or maple syrup: 1 tsp. Optional, but it rounds out the acid.
- Fresh cilantro: 1 Tbsp, plus extra for garnish. Parsley is a milder stand-in.
How to Make Crispy Baked Sweet Potato Rounds with Avocado Cream
Preheat & prep pans
Position racks in upper and lower thirds of oven and preheat to 425 °F (220 °C). Line two large rimmed baking sheets with parchment. Do not use silicone mats—they insulate and reduce crispiness.
Slice evenly
Scrub potatoes but leave the skin on for fiber and structure. Using a mandoline set to ⅛ inch, slice into uniform rounds. Pat completely dry with a lint-free kitchen towel—excess moisture is the enemy of crisp.
Seasoning toss
In a large bowl, whisk cornstarch, smoked paprika, salt, and pepper. Add potato rounds and toss until each slice has a whisper-thin coating. Drizzle with olive oil and toss again until glossy.
Arrange for airflow
Lay rounds in a single layer, barely touching. Overlapping will steam, not roast. Divide between pans; if crowded, bake in batches rather than stacking.
Bake & flip
Bake 10 minutes. Rotate pans front-to-back and switch racks. Bake 6–8 minutes more, until edges are deeply browned and centers have orange-brown spots. They’ll crisp further as they cool.
Blend avocado cream
While potatoes roast, combine avocado flesh, lime zest, lime juice, garlic, coconut yogurt, honey, and cilantro in a mini food processor. Blitz 30 seconds until satin-smooth. Taste; add more salt or lime if needed. Cover surface directly with plastic wrap to prevent browning.
Serve & style
Transfer rounds to a platter. Drizzle (or pipe) avocado cream in decorative stripes, or serve it in a bowl for dunking. Garnish with sesame seeds, lime zest curls, or pomegranate arils for holiday color.
Expert Tips
Use convection if you have it
Convection speeds browning by 2–3 minutes and guarantees even edges. Reduce oven temperature to 400 °F.
Keep the skin on
Nutrients lie just beneath the skin, plus it acts like a built-in bowl for the cream.
Double the batch
Leftovers reheat beautifully and make killer breakfast toppers—just add a fried egg.
Spice swap
For Tex-Mex flair, sub chipotle powder and serve with black-bean salsa.
No mandoline?
Use a sharp chef’s knife and two chopsticks laid beside the potato as a guard for even thickness.
Crisp revival
Pop leftover rounds into an air-fryer at 350 °F for 2 minutes to restore crunch.
Variations to Try
- Mediterranean: swap paprika for za’atar and fold sun-dried tomato paste into the avocado cream.
- Buffalo: brush finished rounds with 2 Tbsp melted vegan butter + 1 Tbsp hot sauce; serve avocado cream blended with 1 Tbsp vegan ranch.
- Everything-bagel: dust rounds with 1 Tbsp everything-bagel seasoning after the oil toss.
- Smoky cheese: sprinkle ¼ cup finely grated smoked vegan cheddar during the last 2 minutes of baking.
Storage Tips
Refrigerate: Cool rounds completely, then layer between parchment in an airtight container up to 4 days. Avocado cream keeps 48 hours when pressed with plastic wrap.
Freeze: Freeze rounds in a single sheet, then transfer to a zip bag for up to 2 months. Reheat directly from frozen at 425 °F for 10 minutes. Do not freeze the cream.
Make-ahead: Blend cream and store in mini jars; slice potatoes morning-of and submerge in salted ice water (prevents browning). Drain and pat dry before seasoning.
