Sometimes you can make a very tasty dish from the simplest ingredients. Here I have a regular recipe for baked vegetables for many years, I pay attention to it only when guests ask for a recipe. One nuance can completely change the usual taste.
Cut into slices using a food processor.
So beautifully cuts carrots.
Also cut the potatoes.
Cut the onion into 8 pieces and mix everything on a baking sheet.
Put in a preheated 180 gr. oven for 20-30 minutes without watering anything.
When the vegetables are almost ready, you need to sprinkle them with salt (spices if desired). Stir, drizzle with oil, and mix again. Bake until tender.
