-
Overcrowding the Baking Sheet: When you place too many vegetables on the baking sheet, they can steam instead of roast. Make sure there’s enough space for air circulation.
-
Not Preheating the Oven: Failing to preheat your oven can lead to uneven cooking. Always preheat to 400°F (200°C) before roasting.
-
Ignoring Seasoning: Skipping salt and pepper can result in bland vegetables. Don’t forget to season both the veggies and the vinaigrette well.
-
Using Old Ingredients: Fresh asparagus and radishes yield the best flavor. Check for freshness before using; wilted or old veggies won’t taste as good.

Rushing the Roasting Time: Not giving enough time for roasting can leave your vegetables undercooked. Aim for 20-25 minutes for perfectly tender veggies.
