Instructions
Preparation & Roasting
- Place a large, rimmed baking sheet on the middle rack and preheat to 425 F (220 C). A hot pan jump-starts caramelization.
- Cut everything into similar 1/2 to 3/4 inch pieces. Pat vegetables dry with a towel to remove surface moisture.
- In a large bowl, toss vegetables with 2 tbsp olive oil, salt, pepper, thyme, rosemary, and garlic until evenly coated.
- Carefully pull the hot sheet pan from the oven. Spread vegetables in a single layer without crowding. Roast 20 minutes, then toss and roast 10 to 15 minutes more until tender with browned edges.
Glaze & Finish
- While veggies roast, simmer balsamic vinegar, maple syrup, Dijon, red pepper flakes, and remaining 1 tbsp olive oil in a small saucepan over medium heat for 2 to 3 minutes until slightly syrupy. Remove from heat.
- Drizzle the glaze over the hot vegetables and toss on the pan. Return to the oven for 3 to 5 minutes to set the glaze. Sprinkle with flaky salt, parsley, and nuts if using.
- Taste and adjust salt or acidity. Serve warm.

- Convection fans on: reduce time slightly and check early.
- Add the glaze at the end so sugars do not burn.

FAQs
Can I roast frozen vegetables?
Yes. Do not thaw. Toss with oil and seasonings, then roast on a preheated pan. Expect a few extra minutes and slightly softer texture.
How do I keep vegetables from getting soggy?
Dry them well, use high heat, preheat the pan, and spread in a single layer with space between pieces.
Which vegetables cook at the same rate?
Brussels sprouts, squash, sweet potatoes, and carrots work well together when cut to similar sizes. More delicate veg like broccoli needs a few minutes less.
Can I make this ahead?
Yes. Roast the vegetables up to 3 days ahead. Reheat until hot, then glaze and return to the oven for a few minutes to set.
Can I substitute honey for maple syrup?
Absolutely. Honey is slightly sweeter, so start with a little less, then adjust to taste.
Final Thoughts
Simple ingredients, a hot oven, and a glossy balsamic finish make these vegetables irresistibly cozy. If you make them, leave a note with your favorite veggie combo. Happy roasting.
