Choosing the Right Sweet Potatoes for Roasting
Best Varieties for Crispy Wedges
Not all sweet potatoes are created equal. For the crispiest, most flavorful wedges, choose:
- Beauregard (orange flesh, widely available)
- Garnet (deep color, sweeter)
- Jewel (firm and earthy, less moisture)
These varieties hold their shape and roast beautifully.
Signs of Fresh vs. Starchy or Dried-Out Sweet Potatoes
- Fresh: Smooth skin, no sprouts, firm to the touch
- Avoid: Wrinkled skin, soft spots, or black discoloration
- Keep them in a cool, dark spot, avoid refrigeration.

Ingredient Spotlight – Garlic Parmesan Sweet Potato Wedges
Fresh Garlic Makes the Flavor Pop
Minced garlic caramelizes in the oven, infusing every wedge with sweet, nutty aroma. Pre-minced jars won’t give the same flavor punch, go fresh.
Parmesan Cheese: Grated vs. Shredded
Use grated Parmesan for maximum coverage and melt. Avoid pre-shredded blends with added fillers — they won’t crisp properly.
Best Herbs to Pair
- Rosemary: earthy, savory depth
- Thyme: subtle, floral edge
- Parsley: for a clean, fresh finish
Pair it all with olive oil or melted butter to ensure every bite is evenly coated.
How to Cut Sweet Potatoes into Perfect Wedges
Knife Technique for Uniform Cooking
- Cut potato in half lengthwise
- Slice each half into 3–4 even wedges
- Try to keep skin-on for texture and nutrients
Uniform wedges mean even browning and cooking.
Soaking and Drying for Extra Crisp
Soak raw wedges in cold water for 30 minutes, then dry thoroughly. This removes excess starch and encourages crispier roasting.
The Secret to Crispy Sweet Potato Wedges
Temperature & Oven Setup
- Preheat oven to 425°F (220°C)
- Use a preheated baking sheet for a hot start
- Line with parchment paper, not foil
Crisping Hacks
- Toss wedges in 1 tbsp cornstarch before oil
- Don’t overcrowd the pan, space helps crisping
- Flip wedges halfway through
You can also add Parmesan toward the end of roasting for ultimate melt + crunch combo.
How to Season and Bake for Maximum Flavor
Garlic Butter Toss vs. Oil-Only
- Oil Only: neutral taste, lighter finish
- Garlic Butter: deeper flavor, indulgent texture
- Tip: Toss raw garlic in at the end to prevent burning
When to Add Parmesan
- Half before baking
- Half in the last 5 minutes of roasting
This prevents the cheese from burning while still getting crisp edges.
Roasting Time & Flip
- Bake for 25–30 minutes
- Flip after 15 minutes for even browning
- Broil for the last 2 minutes if needed
