Herb-Roasted Potatoes, Carrots & Onions

Last weekend, I wanted an easy side dish that would make the whole kitchen smell warm and comforting. I tossed some potatoes, carrots, and onions with olive oil, garlic, and herbs, then let the oven do the rest. The vegetables came out beautifully golden, tender in the middle, and slightly crisp around the edges.

It was such a simple dish, but everyone loved it. I especially enjoy making this when I’m cooking a roast, grilled chicken, or even just a simple weeknight dinner because it goes with almost everything.

Why You’ll Love This Recipe

• Simple everyday ingredients
• Crispy, golden edges and tender vegetables
• Full of garlic and herb flavor
• Easy one-pan side dish
• Perfect for weeknight dinners and holidays
• Naturally vegetarian

Ingredients

• 1½ lb baby potatoes, halved
• 4 medium carrots, peeled and cut into chunks
• 1 large yellow onion, cut into wedges
• 3 tbsp extra-virgin olive oil
• 4 cloves garlic, minced
• 1 tsp dried rosemary
• 1 tsp dried thyme
• 1 tsp Italian seasoning
• ½ tsp paprika
• ½ tsp salt
• ¼ tsp black pepper
• 2 tbsp fresh parsley, chopped
• 1 tbsp fresh lemon juice, optional

Instructions

1. Prepare the Oven

Preheat your oven to 425°F (220°C).

Line a large baking sheet with parchment paper for easier cleanup.

2. Prepare the Vegetables

Place the potatoes, carrots, and onion wedges in a large bowl.

Add the olive oil, minced garlic, rosemary, thyme, Italian seasoning, paprika, salt, and black pepper.

Toss everything thoroughly until the vegetables are evenly coated.

3. Arrange on the Baking Sheet

Spread the vegetables across the baking sheet in a single layer.

Try not to overcrowd the pan. Giving the vegetables enough space helps them roast and brown instead of steaming.

4. Roast

Roast for 35–45 minutes, tossing the vegetables once or twice during cooking.

The potatoes should be fork-tender, the carrots soft, and the edges of the vegetables beautifully golden and caramelized.

5. Finish and Serve

Remove from the oven and sprinkle with fresh parsley.

For a little brightness, add a squeeze of fresh lemon juice before serving.

Serve immediately while the vegetables are warm and golden.

My Tips

• Cut the vegetables into similar-sized pieces so they cook evenly.
• Don’t overcrowd the baking sheet.
• Place the potatoes cut-side down when possible for extra browning.
• Use fresh garlic for the best flavor.
• Toss the vegetables halfway through roasting so they brown evenly.
• If your carrots are particularly thick, cut them a little smaller than the potatoes.
• A final squeeze of lemon balances the richness of the roasted vegetables.

Easy Variations

Mediterranean Style: Add oregano, feta cheese, Kalamata olives, and a drizzle of lemon.

Garlic Parmesan: Sprinkle Parmesan over the vegetables during the final 5 minutes of roasting.

Spicy Version: Add crushed red pepper flakes or a pinch of cayenne.

Honey Herb: Drizzle a small amount of honey over the finished vegetables for a sweet-savory flavor.

Extra Vegetable Version: Add zucchini, bell peppers, mushrooms, or Brussels sprouts.

What to Serve With It

These roasted vegetables are incredibly versatile.

Serve them alongside:

• Roast chicken
• Grilled steak
• Baked salmon
• Pork tenderloin
• Turkey
• Meatloaf
• Grilled chicken tenders
• A fresh green salad

They also make a delicious filling for grain bowls or a simple vegetarian lunch.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days.

For the best texture, reheat them in an oven or air fryer at 375°F (190°C) until hot and lightly crisp again.

Microwaving works too, but the vegetables will be softer.

Frequently Asked Questions

Can I prepare these vegetables ahead of time?
Yes. You can chop the vegetables and mix the seasoning ahead of time. Store everything covered in the refrigerator and roast when you’re ready.

Can I use regular potatoes instead of baby potatoes?
Absolutely. Yukon Gold or red potatoes work especially well. Cut them into evenly sized chunks.

Can I make this recipe in an air fryer?
Yes. Air fry the vegetables at about 400°F (200°C) for 18–25 minutes, shaking the basket several times, until the potatoes are tender and golden.

Why aren’t my vegetables getting crispy?
The most common reason is overcrowding. Use a large baking sheet and spread the vegetables into a single layer with some space between the pieces.
