Description
These Herby Oven Roasted Vegetables turns a colourful pile of everyday vegetables into a seriously tasty side dish. The garlic, herbs, and a splash of vinegar give everything plenty of flavour, while the hot oven brings out those lovely browned edges.
Ingredients
- 62.5 ml olive oil
- 10 ml minced or grated garlic
- 35 ml pure white vinegar
- 7.5 ml dried thyme
- 5 ml coarse salt
- 2.5 ml black pepper
- 5 – 7.5 ml dried rosemary
- 15 ml dried basil
- 600 g peeled and cubed butternut squash
- 300 g cauliflower florets and broccoli florets
- 100 g Brussels sprouts, halved
- 250 g Mushrooms, cut into quarters
- 200 g Red pepper, cut into chunks
- 130 g white onion, cut into chunks
- 225 g potatoes, cut into chunks
- Fresh parsley, for garnish
Instructions
- Preheat the oven to 450⁰F (230⁰C). Line a large baking sheet with parchment paper and lightly spray it with cooking spray.
- In a large mixing bowl, whisk together 62.5 ml olive oil, 10 ml minced or grated garlic, 35 ml white vinegar, 7.5 ml dried thyme, 5 ml coarse salt, 2.5 ml black pepper, 5 – 7.5 ml dried rosemary and 5 ml dried basil.
- Add 600 g cubed butternut squash, 300 g cauliflower and broccoli florets, 100 g halved Brussels sprouts, 250 g mushrooms, 200 g red pepper, 130 g white onion and 225 g cubed potatoes. Toss really well so the vegetables are coated with the oil and herb mixture. Don’t just give them a quick stir, as the seasoning can settle at the bottom of the bowl.
- Spread the vegetables over the prepared baking sheet in a single layer. Try not to pile them up. If they’re crowded, use two baking sheets instead. That little bit of extra space helps the vegetables roast and brown rather than steam.
- Roast for 30 minutes, then carefully stir and turn the vegetables so they cook evenly. Return the pan to the oven and roast for another 15 minutes, checking near the end. The potatoes and butternut squash should be tender inside, while the edges of the vegetables should have some lovely browned bits.
- If the vegetables are tender but you’d like more colour, broil them for another 3 to 5 minutes. Keep an eye on them at this point because the garlic and smaller pieces can brown quickly.
- Scatter fresh or even dried parsley over the vegetables before serving, if you like.

Additional Information
- Can this be frozen? Yes, you can, but the vegetables will be softer than when freshly roasted, particularly the mushrooms and peppers. I prefer not to freeze this dish
- How long can leftovers be stored? Store cooled vegetables in an airtight container in the refrigerator for up to 4 days. Reheat in a 400⁰F (200⁰C) oven for 10 to 15 minutes or use an air fryer until heated through. Microwaving is fine for convenience, but the vegetables will be softer.
- Can the vegetables be prepared ahead? Yes. Chop the vegetables earlier in the day and refrigerate them in a covered container. For the best roasting results, add the olive oil, vinegar, garlic and herbs shortly before cooking.
- Why should the vegetables be cut into similar sizes? Vegetables cook at different speeds, so size matters. Cut potatoes and butternut squash into relatively small cubes, while softer vegetables such as peppers can be slightly larger.
- Why aren’t my vegetables browning? The baking sheet may be overcrowded. Vegetables release moisture as they cook, and when they’re packed together, they can steam instead of roast. Use two baking sheets if needed and keep the vegetables in a single layer.
- Should I stir the vegetables while roasting? Yes. Stir after the first 20 minutes so different sides have a chance to brown. Check them again during the final 10 to 15 minutes because smaller pieces can cook faster.
- Can different vegetables be used? Yes. Carrots, sweet potatoes, parsnips, zucchini, green beans and red onion are good alternatives. Harder vegetables should be cut smaller so they finish cooking with the softer vegetables.
- Can I substitute the white vinegar? Apple cider vinegar is a good substitute and gives the vegetables a slightly fruitier note. Red wine vinegar can also work, although it may change the colour of lighter vegetables.
- Can fresh herbs be used instead of dried? Yes. Fresh thyme, rosemary or basil can be substituted. Add delicate fresh herbs towards the end of roasting to reduce the chance of them burning.
- Why is vinegar used in the seasoning? The vinegar adds acidity, which helps balance the sweetness of the butternut squash and roasted vegetables. It also keeps the garlic and dried herbs from tasting too heavy.
- What should I do if the vegetables are tender but not browned enough? Return the baking sheet to the oven for another 3 to 5 minutes. Watch closely at this stage because the garlic and smaller vegetable pieces can brown quickly.

Herby Oven Roasted Vegetables makes vegetables the part of the meal people actually look forward to. Butternut squash, potatoes, mushrooms, Brussels sprouts, broccoli, cauliflower and peppers roast until tender with browned edges, while garlic, herbs and vinegar add plenty of savoury flavour. It’s colourful, filling and straightforward enough to make whenever a good vegetable side is needed.
