I still remember the first time I served these crispy smashed sweet potatoes at our annual Friends-giving potluck. The platter disappeared in under ten minutes, and I spent the rest of the evening scribbling the recipe on napkins for people who’d never thought to treat sweet potatoes like the best steak-house potato. Since then, these burnished, caramelised coins have become my signature side that doubles as a vegetarian main. They’re the bridge between the marshmallow-topped holiday casserole of my Midwestern childhood and the garlicky-crispy roast potatoes I fell for while living in London. Whether you need a show-stopping centrepiece for Meatless Monday or a make-ahead side that reheats like a dream for Thanksgiving, this recipe delivers sweet-salty crunch with zero stress.

Ingredients You'll Need

Start with 2 lbs (about 4 medium) orange-fleshed sweet potatoes—Garnet or Beauregard varieties strike the best balance of sweetness and dryness. Look for firm, unblemished skins; avoid the refrigerated aisle because cold converts starches to sugars and they’ll turn mushy. Medium width (2–2½ inches) ensures every slice smashes into a two-bite coin that gets maximum crisp edge.

Extra-virgin olive oil adds fruity depth, but avocado oil works for high-heat purists. You’ll need 3 tablespoons total—enough to coat without turning greasy. Melted ghee or brown butter push the flavour into toffee territory if you eat dairy.

For the glaze, reach for raw, floral honey (clover or wildflower) rather than dark buckwheat; its lighter flavour lets the cinnamon sing. Ceylon “true” cinnamon is warmer and less aggressive than cassia, but use what you have. A pinch of flaky salt balances sweetness and accentuates caramelisation.

Optional but game-changing: ½ teaspoon of Aleppo pepper or mild Korean gochugaru introduces a gentle, wine-like heat that blooms under the broiler. Finish with toasted pepitas for crunch and a shower of fresh thyme leaves for colour contrast.

How to Make Crispy Smashed Sweet Potatoes With A Honey Cinnamon Glaze

Preheat & Prep Pan

Position rack in lower-middle of oven; heat to 425 °F (220 °C). Line a rimmed sheet pan with parchment. The slight overhang prevents honey drips from cementing to the metal.

Steam Whole Potatoes

Scrub but do not peel. Place in steamer basket over 1 inch simmering water; cover and steam 18 min until tip of paring knife meets slight resistance. Steaming, not boiling, keeps flavour from leaching out.

Cool & Flatten

Transfer to cutting board; let stand 5 min so starches set. Place a sheet of parchment on top; press the bottom of a heavy skillet to smash each potato into ¾-inch-thick disks. Ragged edges = more crunch.

Season & First Roast

Brush tops generously with olive oil; sprinkle with 1 tsp kosher salt, ½ tsp black pepper. Roast 20 min until bottoms are deep golden. Resist flipping—undisturbed contact equals crust.

Flip & Brush with Glaze

Whisk 2 tbsp honey, ½ tsp cinnamon, 1 tsp oil, pinch Aleppo. Flip potatoes; brush tops with half of glaze. Return to oven 8 min.

Broil for Lacquer

Switch oven to broil. Drizzle remaining glaze; broil 2–3 min until edges bubble and darken. Rotate pan halfway for even colour. Watch closely—honey burns fast.

Expert Tips

Steam, Don’t Boil

Boiling waterlogged potatoes never crisp. A 18-min steam yields fluffy interiors that stay intact when smashed.

Skip the Microwave

Microwaves gelatinise starch unevenly, giving rubbery centres. Steamer basket is hands-off and fool-proof.

Double-Smash Trick

For extra surface area, chill smashed potatoes 10 min, then gently press again before roasting.

Oil the Edges

Use a pastry brush to sweep oil onto the parchment around each potato; this fries the periphery.

Overnight Method

Steam and smash a day ahead; refrigerate on tray uncovered so surfaces dry for even more crunch.

Convection Boost

If your oven has convection, reduce temp to 400 °F and shave 2 min off each roast for extra even browning.

Variations to Try

Storage Tips

Refrigerate: Cool completely, then layer in airtight container between parchment up to 4 days. Reheat on a dry skillet over medium 2 min per side to restore crunch; microwaves soften them.

Freeze: After first roast (before glazing), cool, freeze on tray until solid, then bag 2 months. Bake from frozen 12 min at 425 °F, then proceed with glaze and broil.

Make-Ahead: Steam and smash up to 48 hrs ahead; keep uncovered in fridge so surfaces dry. Bring to room temp 20 min before roasting for even cooking.

Frequently Asked Questions

True yams are starchier and drier; they’ll work but need an extra 2 min steam. In U.S. groceries, what’s labelled “yam” is usually a red-skinned sweet potato—perfect here.

Dilute honey with 1 tsp water and apply only during final 8 min of roasting; broil no more than 3 min watching constantly.

Yes—use half sheet pan but keep potatoes in single layer; timing stays identical.

Steam a minute less next time, cool completely before smashing, and use flat-bottomed glass instead of skillet for gentler pressure.

Air-fry smashed potatoes 12 min at 400 °F, shaking once; brush glaze, then 3 min more. Work in batches for single-layer placement.

Pile on whipped feta, drizzle pomegranate molasses, or stack inside slider buns with arugula and chipotle mayo for a vegetarian pulled-“pork” vibe.
