Ingredients (serves 4–6)

4–5 cups mixed vegetables (broccoli, carrots, bell peppers, zucchini, cauliflower, red onion)
2–3 tbsp olive oil
¾ tsp salt (adjust to taste)
½ tsp black pepper
½ tsp garlic powder or minced garlic
Optional: dried herbs (thyme, rosemary, Italian seasoning), paprika, chili flakes

Essential Tools and Equipment

Large rimmed baking sheet
Parchment paper or foil
Large mixing bowl
Sharp knife
Spatula or tongs

Step-by-step process (detailed)

1. Preheat the oven

Preheat oven to 425°F (220°C). Line a large baking sheet with parchment paper. High heat is essential for browning and caramelization.

2. Prep the vegetables

Wash and dry all vegetables thoroughly. Cut into uniform, bite-sized pieces so everything cooks evenly. Drier vegetables roast better.

3. Season generously

Add vegetables to a large bowl. Drizzle with olive oil, then sprinkle with salt, pepper, garlic, and any optional seasonings. Toss well until every piece is evenly coated.

4. Arrange for roasting

Spread the vegetables on the baking sheet in a single layer, leaving space between each piece. Overcrowding causes steaming instead of roasting—use two pans if needed.

5. Roast until caramelized

Roast for 30–40 minutes, flipping or stirring once halfway through. Vegetables should be golden-brown with crisp edges and tender interiors.

6. Adjust and finish

Remove from oven, taste, and adjust seasoning if needed. Add fresh herbs, a squeeze of lemon, or grated cheese if desired.

7. Serve hot

Serve immediately as a side dish, or use as a base for bowls, salads, or pasta.

Mistakes to avoid

Overcrowding the pan — soggy vegetables
Skipping drying — poor browning
Too little oil — dry, uneven roast
Low oven temperature — bland results
Uneven cuts — inconsistent doneness
