Potato Wedges Overview

Potato wedges are thick-cut potatoes roasted or fried with oil and seasoning. They are a high-carb starchy side that can raise blood sugar quickly, especially in large servings. Potato wedges are not suitable for low-carb, keto, or diabetic-friendly eating. For a lower-carb “wedge” style side, roasted turnips, radishes, or zucchini wedges work better.
