How to make garlic herb roasted vegetables

1. Prep the oven

Preheat your oven to 400°F (200°C) and place a rack in the middle. Line a large baking sheet with parchment paper or lightly grease it.

2. Start with the hearty vegetables

In a large bowl, toss the potatoes, carrots, and red onion with 3 tablespoons olive oil, salt, and pepper until well coated. Spread them out on the baking sheet in a single layer.

Roast for 20 minutes, giving them time to soften and start browning.

3. Add zucchini and herbs

While the vegetables roast, toss the zucchini with the remaining olive oil and a small pinch of salt.

After the first 20 minutes, remove the tray from the oven. Add the zucchini, garlic, thyme, and rosemary. Toss everything together and spread evenly again.

4. Finish roasting

Return the pan to the oven and roast for another 20 minutes, or until all the vegetables are tender with lightly crisped edges.

Serve warm and enjoy.

Helpful tips for best results

• Don’t overcrowd the pan – space helps the vegetables roast instead of steam.
  
• Add zucchini later so it stays tender and doesn’t turn mushy.
  
• Fresh herbs give the best flavor, but dried herbs work if needed (use about half the amount).
  

Variations & swaps

• Replace zucchini with yellow squash, bell peppers, or broccoli
  
• Sprinkle grated parmesan over the vegetables during the last 5 minutes
  
• Sprinkle a small amount of red pepper flakes for mild spiciness
  

What to serve with roasted vegetables

These veggies pair beautifully with:

• Roast chicken or grilled steak
  
• Baked salmon or other fish
  
• Eggs for a hearty brunch plate
  
• Hummus or yogurt sauce for a vegetarian meal
  

Storage & reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days.
Warm them in a 350°F oven or use a skillet to restore their crisp texture. Freezing is not recommended, as the texture will soften too much.
