What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without any complicated steps or hard-to-find items. Most of these are pantry staples or fresh produce you can grab easily.

• Sweet Potatoes: Medium-sized, firm, and preferably uniform in shape for even cooking. I like to use organic if I can find them.
• Olive Oil: For brushing the sweet potatoes before air frying to get that lovely crisp skin.
• Salt & Pepper: Basic seasoning to bring out the natural sweetness and balance the marshmallow drizzle.
• Ground Cinnamon: Adds a warm spice note that pairs beautifully with sweet potatoes and marshmallows.
• Mini Marshmallows: You’ll want these for the drizzle topping. I prefer the classic brand for best melting results.
• Butter: Unsalted, melted, to mix with marshmallows for a smooth drizzle (adds richness and helps the marshmallows melt evenly).
• Brown Sugar: Just a touch to sprinkle over the potatoes before cooking for that caramelized finish.
• Optional Toppings: Chopped pecans or walnuts for crunch, a pinch of sea salt to contrast the sweetness, or a drizzle of maple syrup if you want it extra sweet.

If you want a dairy-free option, swap the butter with coconut oil—it works surprisingly well. And if fresh sweet potatoes aren’t in season, frozen pre-cut sweet potatoes can be used, but cooking times might vary.

Equipment Needed

• Air Fryer: Obviously the star here. A basket-style air fryer with at least 3.5 quarts capacity works best for even cooking.
• Sharp Knife: For the Hasselback cuts—make sure it’s sharp to create thin, even slices without cutting all the way through.
• Cutting Board: Sturdy and spacious enough for safe slicing.
• Pastry Brush: To brush olive oil and melted butter evenly on the potatoes and marshmallow drizzle.
• Small Mixing Bowl: For melting butter and mixing in marshmallows.
• Tongs or Spatula: To handle the hot sweet potatoes safely when removing them from the air fryer.

If you don’t own an air fryer yet, a convection oven can be a decent substitute, but cooking times and crisping results will differ. I’ve tried this recipe in both, and the air fryer definitely gives the best texture with less fuss. Also, keeping your knife sharp is key for making clean Hasselback slices without squashing the potato.

Detailed Preparation Method

1. Prep the Sweet Potatoes (10 minutes): Start by washing and drying 3 medium sweet potatoes. Place one on the cutting board and carefully make 1/8-inch thick slices across the potato, stopping about 1/4 inch before cutting all the way through. The goal is to keep the potato intact at the bottom so it fans out like a little accordion.
2. Season (5 minutes): Use a pastry brush to coat the sweet potatoes evenly with 2 tablespoons (30 ml) of olive oil. Sprinkle with 1 teaspoon (5 g) salt, 1/2 teaspoon (1 g) ground cinnamon, and a pinch of black pepper. Don’t forget to sprinkle a tablespoon (12 g) of brown sugar over the top for caramelization.
3. Preheat the Air Fryer (3 minutes): Turn on your air fryer to 375°F (190°C) and let it preheat while you finish prepping.
4. Cook the Sweet Potatoes (25 minutes): Place the sweet potatoes in the air fryer basket, cut side up, ensuring they aren’t touching to allow hot air circulation. Cook for 12 minutes, then flip and cook for another 10-13 minutes until the edges are crispy and the centers tender when poked with a fork.
5. Prepare the Marshmallow Drizzle (5 minutes): While the potatoes cook, melt 2 tablespoons (28 g) unsalted butter in a small bowl. Stir in 1/2 cup (75 g) mini marshmallows until smooth and glossy. If it’s a bit thick, microwave in 15-second bursts, stirring in between.
6. Drizzle and Final Cook (5 minutes): Carefully remove the sweet potatoes from the air fryer. Using the pastry brush, drizzle the melted marshmallow mixture over the potatoes, letting it seep between the slices. Return to the air fryer and cook for an additional 3-5 minutes at 350°F (175°C) until the marshmallow topping is lightly browned and bubbly.
7. Serve: Garnish with optional chopped nuts or a sprinkle of sea salt. Serve warm.

Tip: Don’t rush the slicing—thin, even cuts ensure the potatoes cook evenly and the marshmallow drizzle melts perfectly between them. Also, watch the marshmallow closely during the final cook so it browns but doesn’t burn.

Cooking Tips & Techniques

One of the trickiest parts is getting those Hasselback slices just right—too thick and the potato won’t fan out properly, too thin and it might fall apart. I use chopsticks on either side of the potato as a slicing guide to avoid cutting all the way through. It’s a little trick that saves so much trouble!

When it comes to air frying, don’t overcrowd the basket. The hot air needs to circulate to make those edges crispy. If you have a smaller air fryer, cook the sweet potatoes one at a time or in batches.

For the marshmallow drizzle, melting butter first is key. It smooths out the marshmallows and keeps them from clumping or becoming grainy. If the mixture feels too thick, a splash of milk or cream helps loosen it up, but use sparingly.

Keep an eye on the final browning stage—marshmallows can go from perfectly golden to burnt quickly. I recommend staying close and checking every minute once you put the potatoes back in the air fryer.

Lastly, don’t skip the sprinkle of brown sugar before cooking. It’s a simple step that brings out caramel notes and deepens the flavor beautifully.

Variations & Adaptations

• Vegan Version: Use coconut oil instead of butter and vegan marshmallows to keep it plant-based and still delicious.
• Spicy Sweet: Add a pinch of cayenne pepper or smoked paprika to the seasoning mix for a pleasant kick that contrasts with the marshmallow sweetness.
• Nutty Crunch: Sprinkle chopped toasted pecans or walnuts on top after the final drizzle for added texture and flavor.
• Gluten-Free Option: This recipe is naturally gluten-free as long as marshmallows are certified gluten-free.
• Seasonal Twist: Swap out the marshmallow drizzle for a drizzle of cinnamon-spiced caramel sauce in the fall or a lemon glaze in the spring for a fresh vibe.

A personal favorite variation I tried was adding a smear of almond butter between the Hasselback slices before air frying. It created a rich, nutty surprise inside that paired insanely well with the sweet marshmallow topping.

Serving & Storage Suggestions

Serve these air fryer Hasselback sweet potatoes warm, right out of the fryer, to enjoy the crispy edges and gooey marshmallow at their best. They look lovely on a festive platter garnished with chopped nuts or fresh rosemary sprigs for a pop of color.

This dish pairs wonderfully with roasted chicken or turkey for a comforting meal, or alongside a fresh green salad to balance the sweetness. Hot apple cider or a spiced chai latte also complement the flavors perfectly.

To store leftovers, place cooled sweet potatoes in an airtight container and refrigerate for up to 3 days. Reheat gently in the air fryer at 350°F (175°C) for 5-7 minutes to bring back the crispiness. Avoid microwaving if possible, as it makes the marshmallow topping gummy.

Flavors actually deepen after resting overnight, so if you can resist, try making them a few hours ahead—the marshmallow drizzle sets nicely but stays soft and dreamy.

Nutritional Information & Benefits

One serving of these air fryer Hasselback sweet potatoes (about 1 medium potato with drizzle) offers roughly 250-300 calories, depending on portion size. They provide a good dose of fiber, vitamin A, and potassium thanks to the sweet potatoes.

The olive oil and butter contribute healthy fats, while the marshmallows add sugar, so this is best enjoyed as an occasional treat. Sweet potatoes are known for their antioxidant properties and are a great alternative to regular potatoes for those watching blood sugar.

This recipe is naturally gluten-free and can be adapted for vegan diets with simple swaps. From a wellness perspective, it’s a cozy yet mindful way to enjoy a sweet, satisfying dish without feeling weighed down.
