Ingredients for Maple Dijon Roasted Vegetables – Crispy, Caramelized

Exact amounts are in the printable recipe card below — here's what you'll need at a glance.

Main Ingredients

• 1 lb Brussels sprouts, trimmed and halved
• 1 lb carrots, peeled and cut into 2-inch batons
• 1 lb sweet potatoes, peeled and cut into 1-inch cubes
• 1 large red onion, cut into thick wedges

Seasonings & Flavors

• 3 Tbsp pure maple syrup
• 2 Tbsp Dijon mustard
• 2 Tbsp olive oil
• 1 Tbsp apple cider vinegar
• 1 tsp kosher salt
• 1/2 tsp black pepper
• 1/4 tsp crushed red pepper flakes

Optional Toppings

• (Optional) Toasted pecans
• (Optional) Crumbled goat cheese
• (Optional) Fresh thyme leaves
• (Optional) Flaky sea salt

Ingredient Notes

• Brussels sprouts: The cut side must face down on the pan. That flat surface makes deep browning.
• Carrots: Cut them smaller than sweet potatoes so all pieces finish at the same time.
• Sweet potatoes: Their natural sugar burns fast. Keep the cubes at least 1 inch.
• Red onion: Wedges soften and sweeten. Thin slices would blacken.
• Maple syrup: Use pure maple syrup, not pancake syrup. Pancake syrup thins out and burns.
• Dijon mustard: Smooth Dijon helps the glaze cling. Whole grain works but adds texture.
• Olive oil: Oil carries heat and helps browning. Do not skip it or the vegetables dry out.
• Apple cider vinegar: A small splash wakes up the sweet glaze without making it watery.

How to Make Maple Dijon Roasted Vegetables – Crispy, Caramelized Step by Step

Preheat the oven and prepare the pan

Set oven to 425°F. Line a large rimmed baking sheet with parchment paper. Watch for dark pans, which can burn the maple glaze faster.

Cut the vegetables

Cut Brussels sprouts in half through the stem. Peel and cut carrots into 2-inch batons. Cube sweet potatoes into 1-inch pieces. Cut onion into thick wedges. Watch for uneven pieces; they will cook at different speeds.

Whisk the glaze

In a large bowl, whisk maple syrup, Dijon mustard, olive oil, apple cider vinegar, salt, pepper, and red pepper flakes until smooth. The glaze should cling to a spoon, not run off.

Coat the vegetables

Pour the glaze over the vegetables. Toss with your hands until every piece is glossy. Watch for puddles of glaze at the bowl bottom; toss again if needed.

Arrange on the sheet pan

Spread vegetables in a single layer. Place Brussels sprouts cut side down. Leave space between pieces. Watch for overcrowding, which causes steaming and soggy edges.

Roast and stir

Roast for 22–26 minutes. At 12 minutes, remove the pan and flip the vegetables with a thin spatula. Look for sizzling edges and deep brown spots. Watch for dark corners; move pale pieces to the edge.

Finish and serve

Roast 10–14 more minutes until vegetables are tender and deeply caramelized. You should smell a sweet, nutty aroma. If the glaze darkens too fast, drop the oven to 400°F. Let rest 3 minutes before serving.

Pro Tips for the Best Maple Dijon Roasted Vegetables – Crispy, Caramelized

• Ingredient prep: Cut root vegetables to the same thickness. Soft vegetables like onion can be larger. This keeps cook times even.
• Common mistake and fix: Overcrowding the pan is the #1 failure. Wet vegetables sit too close and steam instead of brown. Use two sheet pans if needed. If they already came out soggy, return them to a 425°F oven for 8–10 minutes on a dry pan to crisp.
• Timing or temperature: Start at 425°F for browning. If the glaze is getting too dark before the vegetables are tender, drop to 400°F and add 5 minutes.
• Make-ahead or storage: Chop vegetables up to one day ahead. Store them dry in a sealed container. Do not add the glaze until just before roasting.

Storing and Reheating Maple Dijon Roasted Vegetables – Crispy, Caramelized

Reheating in the Microwave

Microwave at 70% power for 45–60 seconds. Place a damp paper towel over the bowl to prevent sogginess.

Frequently Asked Questions about Maple Dijon Roasted Vegetables – Crispy, Caramelized

Why are my Maple Dijon Roasted Vegetables soggy?

Soggy vegetables usually mean the pan was overcrowded. When pieces touch, they release steam instead of browning. Spread the vegetables in a single layer with space between pieces. If they are already soggy, put them on a dry sheet pan and roast at 425°F for 8–10 minutes.

Can I make Maple Dijon Roasted Vegetables ahead of time?

Yes. Chop the vegetables up to 24 hours ahead and store them dry in a sealed container. Whisk the glaze and keep it in a separate jar. Toss and roast just before serving. The texture is best fresh, but leftovers hold for a few days.

How long do Maple Dijon Roasted Vegetables last in the fridge?

Store them in a shallow glass container with a fitted lid. They stay safe for 3–4 days. The edges soften over time. Reheat in the oven to bring back some crispness.

What vegetables work best for Maple Dijon Roasted Vegetables?

Brussels sprouts, carrots, sweet potatoes, and red onion work best. You can also use parsnips, butternut squash, or cauliflower. Cut dense vegetables smaller so they finish at the same time. Avoid watery vegetables like zucchini unless you add them later.

Can I make Maple Dijon Roasted Vegetables for Thanksgiving?

Yes. This is a strong Thanksgiving side dish because it roasts at high heat while the oven is already hot. Double the recipe and use two sheet pans. The maple-Dijon glaze feels festive without being heavy.
