Ingredients
• 2 pounds carrots, peeled and cut into uniform pieces
• 6 whole potatoes, washed and cut into even pieces (skins left on)
• 1 whole sweet onion, peeled and cut into eighths
• 3 cloves garlic, minced
• 6 tablespoons olive oil
• ½ teaspoon dried thyme
• ½ teaspoon dried parsley
• Salt, to taste
• Black pepper, to taste
Instructions
Step 1: Preheat and Prep Vegetables
Preheat your oven to 475°F (245°C).
Peel and cut the carrots into similar-sized pieces to ensure even cooking.
Wash the potatoes thoroughly and cut into small chunks. There’s no need to peel them—keeping the skins on adds flavor and texture.
Peel the onion and cut it into eighths. Mince the garlic.
Step 2: Season the Vegetables
In a large mixing bowl, add the carrots, potatoes, and onion pieces. Drizzle with 6 tablespoons of olive oil.
Sprinkle in the minced garlic, dried thyme, parsley, salt, and black pepper.
Toss well until all the vegetables are evenly coated in oil and seasonings.
Step 3: Roast the Vegetables
Spread the seasoned vegetables in a single layer on a large baking sheet. Avoid overcrowding to ensure they roast rather than steam.
Cover the baking sheet tightly with aluminum foil and roast in the preheated oven for 45 minutes. This allows the vegetables to begin cooking through while retaining moisture.
Step 4: Uncover and Caramelize
After 45 minutes, remove the foil.
Continue roasting uncovered for an additional 30 minutes, stirring every 10 minutes. This encourages caramelization and crispy edges.
The vegetables are done when they’re golden brown, slightly crisp on the outside, and tender on the inside.
Step 5: Finish and Serve
Taste and adjust seasoning if needed—sometimes a little extra salt or black pepper is all it takes to bring out the full flavor.
Transfer to a serving dish and serve hot, garnished with a pinch of fresh herbs if desired.
Tips for Success
• Cut veggies evenly to ensure they cook at the same rate. Large uneven chunks will either burn or remain underdone.
• Don’t skimp on the olive oil—this helps the veggies crisp and brown rather than steam.
• Use a large baking sheet or two smaller ones to avoid crowding. Overcrowding will prevent browning.
• Add fresh herbs at the end for a pop of color and brightness—think chopped parsley or thyme.
• Check for doneness with a fork—if it slides in easily, your veggies are ready.
Storage and Reheating
• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: While you can freeze roasted vegetables, their texture will soften. Store in airtight freezer bags for up to 1 month.
• Reheating: For best results, reheat in the oven at 375°F (190°C) for 10–15 minutes to maintain crispness. You can also reheat in a skillet or microwave, though the latter may soften the edges.
Serving Suggestions
• Pair with roasted chicken, pork loin, or grilled steak
• Serve as a vegetarian main with a dollop of Greek yogurt or a poached egg on top
• Toss with cooked quinoa or lentils for a hearty grain bowl
• Add to a warm salad with arugula and a balsamic glaze drizzle
