Let’s get slicing!

What Are Sweet Potatoes

Before we slice and dice, let’s talk about what makes this root vegetable so special! Sweet potatoes are starchy, sweet-tasting root vegetables native to the Americas. Despite common confusion, sweet potatoes are completely different from yams and ordinary white potatoes:

• Nutrient Density: They are packed with fiber, vitamin C, potassium, and beta-carotene. This gives orange-fleshed varieties their vibrant color.
• Varieties: While orange-fleshed varieties like Beauregard and Jewel are most commonly found in grocery stores. You can also find purple sweet potatoes and white-fleshed Japanese sweet potatoes.
• Prep Safety Tip: Because sweet potatoes are naturally firmer than standard russet or red potatoes, always use a sharp Chef’s knife and create a flat side on your potato right away to prevent rolling.

How to Prep Sweet Potatoes (Washing & Peeling)

Properly prepping your sweet potatoes before slicing ensures clean cuts, great texture, and maximum kitchen safety. Follow these simple steps to get your potatoes board-ready!

1. Scrub & Wash Thoroughly: Because sweet potatoes grow underground, their outer skin carries dirt and debris. Simply wash: Hold your potato under cool running water and scrub it gently with a produce brush. Skip the soap or chemical washes. Plain water and gentle scrubbing are all you need!

2. Dry Completely: Pat the sweet potato completely dry with a clean kitchen towel or paper towel. Moisture is the enemy of knife safety! A slippery potato makes your knife more likely to slip while cutting.

3. Peel or Leave the Skin On: Optional based on your recipe. Decide whether to peel based on your dish:

• To Peel: Hold the potato firmly at one end and use a sharp vegetable peeler (a Y-peeler works wonders here!) working in long strokes away from your body.
• Keep the Skin: Leaving the skin on adds extra fiber, nutrient value, and delicious texture. It is especially great for rustic wedges and crispy roasted rounds!

4.Trim Blemishes & Ends: Slice off a tiny sliver at both tapered tips, and use the tip of a vegetable peeler or paring knife to nick out any dark spots, eyes, or bruised areas.

How To Cut Sweet Potatoes: Wedges

Sweet potato wedges are hearty, rustic, and perfect for dipping into your favorite sauces or serving as a wholesome side dish.

How to Cut Wedges:

1. Trim the ends: Slice off both tips of the sweet potato.
2. Cut lengthwise: Cut the sweet potato in half end-to-end to create two long pieces.
3. Halve again: Lay each half flat-side down on your cutting board for stability, and slice lengthwise again so you have four long quarters.
4. Angle into wedges: Place each quarter flat-side down, angle your knife toward the center ridge, and slice down the middle to form thick, classic wedges.

How To Cut Sweet Potatoes: Diced

Diced sweet potatoes are incredibly versatile. It is ideal for hash, breakfast scrambles, grain bowls, soups, and chili.

How to Cut Diced Sweet Potatoes:

1. Trim & Stabilize: Cut off the ends and slice a thin strip off one side of the potato to make a flat base.
2. Slice into Planks: Place the flat side down and cut the potato lengthwise into even slabs (around ½-inch thick for medium dice, or ¼-inch thick for small dice).
3. Cut into Sticks: Stack 2–3 slabs at a time and slice lengthwise to create long matchsticks (julienne).
4. Dice into Cubes: Turn the matchsticks horizontally and slice across to form uniform cubes.

How To Cut Sweet Potatoes: Rounds

Slicing sweet potatoes into rounds (or coins) is the easiest cut of all! Rounds are ideal for making scalloped dishes, baking into homemade sweet potato chips, or roasting as a simple side.

How to Cut Rounds:

1. Trim: Slice off both ends of the sweet potato.
2. Slice Crosswise: Hold the potato firmly with your non-dominant hand using the “claw” grip (fingertips curled inward).
3. Choose Your Thickness: Cut straight across the potato horizontally:
   • Thin Coins (⅛-inch): Best for crispy chips (a mandoline works great here!).
   • Thick Rounds (½-inch to ¾-inch): Best for roasting or topping with savory spreads.

How To Cut Sweet Potatoes: Fries

Who doesn’t love crispy, golden sweet potato fries? The secret to restaurant-quality fries at home starts with cutting them into long, uniform sticks so they bake evenly without burning.

How to Cut Fries:

1. Trim & Create a Flat Base:Prerequisite for knife safety. Slice off both ends of the sweet potato. Trim a thin slice off one side lengthwise so the potato sits completely flat on your cutting board.

2. Slice into Even Planks: With the flat side down, slice the sweet potato lengthwise into slabs that are ¼-inch to ½-inch thick, depending on your preferred fry size.

3. Cut into Sticks (Fries): Stack 2 slabs at a time and slice lengthwise into long, uniform fries matching the thickness of your planks.

4. Soak for Extra Crispiness: Optional pro tip. Soak your cut fries in cold water for 30 minutes to remove excess starch. Pat thoroughly dry with a towel before tossing with cornstarch, oil, and seasonings before baking!

Now that you know how to cut sweet potatoes into wedges, diced cubes, rounds, and fries, adding fresh produce to your weekly meal plan is easier than ever! Remember to keep your knife sharp, use a stable cutting board, and always start with a flat edge for safety.
