 Ingredients

You only need a handful of everyday ingredients to make this dish, but together, they create something truly special:

• 2 pounds carrots, peeled and cut into chunks
• 6 whole potatoes, scrubbed and diced (leave the skin on for texture and nutrients)
• 1 large sweet onion, peeled and cut into eighths
• 3 cloves garlic, minced
• 6 tablespoons olive oil
• ½ teaspoon dried thyme
• ½ teaspoon dried parsley
• Salt and black pepper, to taste

Optional Add-Ins:

• A dash of smoked paprika for warmth
• Fresh rosemary or oregano instead of dried herbs
• A splash of balsamic vinegar added during the final 10 minutes of roasting for tang

 Time Breakdown

• Prep Time: 15 minutes
• Cook Time: 1 hour 15 minutes
• Total Time: 1 hour 30 minutes
• Servings: 6 to 8

 Step-by-Step Instructions

1. Preheat the Oven

Begin by preheating your oven to 475°F (245°C). This high temperature is key to achieving beautifully caramelized edges while keeping the insides tender.

2. Prepare the Vegetables

• Peel the carrots and cut them into 1-inch chunks.
• Scrub the potatoes (no need to peel unless preferred) and dice them into evenly sized pieces to match the carrots.
• Cut the sweet onion into eighths. This gives large, flavorful wedges that soften and sweeten in the oven.
• Mince the garlic cloves finely — they’ll infuse the vegetables with rich, aromatic flavor as they roast.

Tip: Try to keep the size of your vegetable pieces relatively uniform for even cooking.

3. Season and Toss

Place all the chopped vegetables in a large mixing bowl. Add:

• 6 tablespoons of olive oil
• The minced garlic
• Dried thyme and parsley
• Salt and freshly cracked black pepper, to taste

Toss everything together thoroughly until each piece is glistening and coated in the oil and seasoning.

Use your hands or a spatula to really work the oil and spices into the crevices — this is where the flavor lives!

4. Roast to Perfection

Spread the seasoned vegetables onto a large baking sheet (or two if needed) in a single layer. Crowding the pan causes steaming instead of roasting, so give them space!

Cover the pan loosely with foil and roast for 45 minutes. This allows the vegetables to soften without drying out.

After 45 minutes, remove the foil, give the veggies a stir, and continue roasting for another 30 minutes, stirring every 10 minutes to ensure even browning and crispy edges.

You’re looking for golden brown edges, fork-tender potatoes, and a slight sweetness from the caramelized onions.

5. Serve and Savor

Once the vegetables are roasted to perfection, transfer them to a serving dish or platter. Garnish with an extra sprinkle of fresh herbs if you like, and serve warm alongside your favorite entrée.

 Storage & Reheating Tips

• Refrigerate leftovers in an airtight container for up to 4 days.
• Reheat in the oven at 375°F (190°C) for 10–15 minutes, or in an air fryer to restore crispiness.
• Freeze in a zip-top bag for up to 2 months, though texture may soften slightly upon thawing.

 Variations and Add-Ons

• Add parsnips or turnips for more root veggie flavor
• Use baby potatoes and roast them whole for a more rustic look
• Add brussels sprouts halves in the last 30 minutes of roasting
• Finish with a grated Parmesan sprinkle for an umami boost
