Easy Oven Roasted Vegetables (Crispy & Healthy Side Dish)

This sheet-pan side is easy and comforting and goes with just about anything. The veggies are tender in the middle with crisp golden edges, and the herbs give the whole thing a fresh taste.

It’s also an easy way to clean out the fridge: Use similar vegetables that you have, keep the seasoning and voilà!

Ingredient Notes & Substitutions

Potatoes: Baby potatoes or Yukon Gold are perfect for this. If using larger potatoes, halve or quarter them so they roast evenly.

Parsnip: If you can’t find parsnips, substitute sweet potato, turnips or extra carrots.

Red onion: Yellow is cool also. It’s better to add the onion later so it doesn’t dry out too much.

Dried thyme: Italian seasoning or dried rosemary both are fine (use less if you think the rosemary might be very strong).

Fresh basil + parsley: Work with what you’ve got (cilantro, dill or chives are great here, too).

Olive oil: Avocado oil makes a good neutral but somewhat more expensive substitute for higher-heat roasting.

How to Make Roasted Vegetables

  • Preheat the oven to 425 degreesF (220 degreesC). Line a rimmed sheet pan with parchment paper and set aside.
  • Prepare the vegetables: Chunk potatoes, slice carrots thick and chop parsnip into chunks the size of the potatoes. Peel and crush the cloves of garlic Waterbubble. Cut red onion into wedges.

Expert Tips

  • Cut everything the same size so that it finishes cooking at the same time.
  • Don’t not overcrowd the pan: veggies want some room to brown, rather than steam.
  • Toss in onion toward the end, because it will taste sweet and remain supple, not parched.
  • You may need to drop your oven temperature to 400°F (205°C) and roast a few minutes more, depending on how hot your oven runs.
  • For additional browning, broil for 1-2 minutes at the end (watch very close).
  • Taste at the end and season with a final pinch of salt if needed.
  • Fresh herbs are added after roasting so they remain bright.
  • If the veggies appear dry halfway through roasting, drizzle with 1–2 tsp oil and stir.

Storage & Freezing

  • Fridge: In an airtight container and for 4 days.
  • Reheat: Reheat in a 400°F (205°C) oven or air fryer until hot and crisped. Works in the microwave, but edges get soft.
  • Freezing: Cool roasted veggies and store in a freezer-safe container, freeze for up to 2 months.
  • Thawing: Thaw in the refrigerator overnight and reheat in oven to restore texture.

Variations

  • Add bell peppers last 15 minutes.
  • Toss in smoked paprika for a more complex flavor.
  • If you like, add cherry tomatoes during the last 10 minutes for a juicy finish.
  • And to keep things nice and bright, let’s finish with some lemon zest + a squeeze of its juice.
  • Sprinkle with Parmesan just after roasting for a savory twist.
