How to Make Oven Roasted Vegetables Recipe
Step 1: Prepare the Oven and Vegetables
First things first: preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper for easy cleanup. While the oven warms, chop all your vegetables into similar-sized pieces to ensure they cook evenly and look pretty together.
Step 2: Toss the Vegetables with Seasonings
In a big mixing bowl, combine the broccoli, cauliflower, both colors of bell peppers, zucchini, and red onion. Drizzle with olive oil and sprinkle garlic powder, dried Italian herbs, salt, and pepper over the top. Toss everything well so each bite will be perfectly seasoned and coated in oil that helps with caramelization.
Step 3: Arrange and Roast
Spread your seasoned vegetables in a single layer on the prepared baking sheet. Taking care not to overcrowd them allows the hot air to circulate and the veggies to get those irresistible browned edges. Pop the pan into the oven and roast for about 25 to 30 minutes, stirring once halfway through for even cooking.
Step 4: Finish and Garnish
When the vegetables are tender and beautifully roasted, remove them from the oven. If you fancy, sprinkle freshly grated Parmesan and some chopped parsley over the hot vegetables to add brightness and a touch of indulgence. Serve immediately to enjoy that perfect blend of textures and flavors.

Side Dishes
This Oven Roasted Vegetables Recipe is incredibly versatile and complements a wide range of mains – from grilled chicken or fish to hearty grain bowls and pasta dishes. It can also star as a wholesome plant-based entrée atop a bed of quinoa or wild rice, making your meals both balanced and vibrant.
Creative Ways to Present
Want to impress? Serve these roasted veggies over creamy mashed potatoes or swirl them through garlic-infused pasta. You can also toss them into warm pita pockets with hummus for a quick, delicious lunch or scatter atop homemade pizza before the final bake to add color and texture.
Make Ahead and Storage
Storing Leftovers
If you have leftovers (which might be unlikely because they are that good), store them in an airtight container in the refrigerator for up to four days. This keeps them fresh and ready for quick reheating or even chilling to eat as a cold salad.
Freezing
While freezing is possible, it’s best to consume this Oven Roasted Vegetables Recipe fresh or refrigerated. Freezing can alter the texture of some vegetables, making them a bit mushier when thawed. If you do freeze, use within a month and thaw gently in the fridge before reheating.
Reheating
To reheat, spread the vegetables on a baking sheet and warm them in a 350°F (175°C) oven for 10-15 minutes to bring back some crispness. Microwaving is quicker but may result in softer veggies. A quick sauté in a hot pan also revives their texture nicely.
FAQs
Can I add other vegetables to this Oven Roasted Vegetables Recipe?
Absolutely! Carrots, potatoes, sweet potatoes, or Brussels sprouts make excellent additions. Just chop them to similar sizes and note that heartier vegetables might need a bit longer to roast, so add them accordingly.
Is this recipe suitable for vegans and gluten-free diets?
Yes! This Oven Roasted Vegetables Recipe is naturally vegan and gluten-free as long as you skip the optional Parmesan or substitute it with a plant-based alternative.
How do I ensure even roasting of the vegetables?
Cut all vegetables into pieces of similar size and avoid overcrowding the pan on the baking sheet. Stirring once halfway through cooking also helps promote even browning.
Can I prepare this recipe ahead of time?
You can prep and chop the vegetables a few hours in advance, but for best flavor and texture, toss them with oil and seasonings just before roasting.
What can I use instead of olive oil?
Olive oil adds its own mild, fruity flavor and helps with browning, but you can substitute other oils with high smoke points like avocado oil or grapeseed oil if you prefer.
