Ingredients

Scale

2 medium bell peppers, cut into 1-inch pieces (red, yellow, or orange)
2 medium zucchini, ends trimmed, cut into 1/2-inch pieces
1 small sweet potato, scrubbed and cut into 3/4-inch pieces
1 small red onion, cut into 1-inch cubes
1 small head broccoli (or 8 oz Brussels sprouts), cut into florets
3 tbsp extra virgin olive oil
1 tbsp Dijon mustard (or sub 1 tbsp more olive oil)
2 tsp Italian seasoning
1 tsp kosher salt
1/2 tsp garlic powder
1/2 tsp ground black pepper
3 tbsp grated Parmesan cheese (optional)

Instructions

Preheat oven to 400°F. If using two baking sheets, position racks in upper and lower thirds of oven.
Prepare baking sheets with non-stick spray or parchment paper.
Combine vegetables in a large bowl. Add olive oil and Dijon mustard. Toss to coat.
Add seasoning: Sprinkle in Italian herbs, garlic powder, salt, and pepper. Toss again.
Distribute evenly on two baking sheets in a single layer, giving vegetables space.
Roast for 25–35 minutes, tossing halfway and rotating pans. Look for crisp edges and fork-tender texture.
Add Parmesan during last 5 minutes of roasting or after removing from oven.
Serve hot or at room temperature with extra seasoning to taste.

Notes

💡 Notes

Dijon adds flavor depth but can be replaced with more olive oil if preferred.
For extra crispiness, use convection mode at 375°F.
Mix and match veggies based on seasonality — carrots, parsnips, squash, or asparagus work great.
Make-ahead: Roast early and reheat before serving.

📦 Storage & Reheating

Refrigerate: Store in airtight container for up to 5 days.
