Uniform sizing ensures even cooking and consistent timing—no peeling needed, just a good scrub. Spread in a single layer on a baking sheet.
Quick hack: Start slower-cooking veggies first; add quick ones like asparagus later to avoid over-browning. Sprinkle garlic, onions, thyme, or rosemary toward the end for max flavor.
Slide into the preheated oven and stir once or twice during roasting. This simple step guarantees even browning and texture—trust me, it's transformative.
Let them roast until golden, crispy outside, and tender inside. Use this time to prep the rest of your meal or unwind. Serve hot and savor!
