Ingredients :
1 large bell pepper, cored and cut into strips
2 medium zucchini, sliced into 1/2-inch thick rounds
1 medium sweet potato, peeled and cut into 1/2-inch cubes
1 red onion, cut into wedges
2 cups broccoli florets
2 tablespoons olive oil
1 tablespoon Dijon mustard
1 teaspoon Italian seasoning
1/2 teaspoon garlic powder
Salt and pepper, to taste
1/4 cup grated Parmesan cheese (optional)
Parmesan cheese pairs well with many dishes like garlic butter chicken with lemon Parmesan linguine if you want a full meal idea.
Directions :
- Preheat your oven to 400°F (200°C). Line two baking sheets with parchment paper to prevent sticking and facilitate easy cleanup.
- In a large bowl, combine the bell pepper strips, zucchini rounds, sweet potato cubes, red onion wedges, and broccoli florets, ensuring all are evenly mixed.
- Drizzle olive oil and Dijon mustard over the vegetables. Sprinkle with Italian seasoning, garlic powder, salt, and pepper. Toss thoroughly until every piece is evenly coated with the mixture.
- Spread the vegetables in a single layer on the two prepared baking sheets, making sure they are not overlapping to allow even roasting and caramelization.
- Place the baking sheets in the oven and roast for 20 minutes. This initial roasting softens the vegetables and begins browning.
- After 20 minutes, rotate the pans for even heat distribution. Flip the vegetables with a spatula to expose all sides, then roast for another 10-15 minutes until they become golden and tender.
- During the last 5 minutes of roasting, sprinkle the grated Parmesan cheese evenly over the vegetables to melt slightly and add a savory crust.
- Once roasted to desired tenderness and golden color, transfer the vegetables to a serving bowl. Serve warm as a delicious side dish or incorporate into salads, sandwiches, or grain bowls for extra flavor and texture.

FAQs
Q: Can I roast these vegetables at a different temperature?
A: Yes. You can roast at 425°F (220°C) for a shorter time (about 20–25 minutes) to get more browning. Watch them so they do not burn.
Q: Can I skip the Dijon mustard?
A: Yes. Dijon adds a little tang, but you can skip it or use a teaspoon of lemon juice instead.
Q: How do I keep sweet potato from being too hard?
A: Cut sweet potato into small, even cubes and make sure the pan is hot enough. You can par-cook sweet potato in the microwave for 2–3 minutes before roasting.
Q: Can I use frozen vegetables?
A: Fresh gives best texture. If you use frozen, thaw and pat dry so they roast instead of steam.
Q: Is Parmesan required?
A: No. Parmesan adds a savory crust, but the dish is good without it.
