How to Make Roasted Carrots, Potatoes, and Onions Step by Step

Step 1: Preheat the Oven

Preheat your oven to around 400–425°F (200–220°C). A hot oven helps the vegetables roast evenly and develop that golden color.

Step 2: Prepare the Vegetables

Peel and cut the carrots into even pieces. Chop the potatoes into chunks and slice the onions into wedges. Try to keep everything similar in size so they cook evenly.

Step 3: Season and Toss

Place the vegetables in a large bowl, drizzle with olive oil, and season with salt, pepper, and your favorite herbs. Toss until everything is well coated.

Step 4: Arrange on a Baking Sheet

Spread the vegetables in a single layer on a baking sheet. Avoid overcrowding so they roast instead of steam. 1

Step 5: Roast

Roast for about 40–50 minutes, stirring halfway through, until the vegetables are tender and golden brown. 2

Step 6: Serve Warm

Remove from the oven and serve immediately while warm and slightly crisp.

Expert Tips
