Getting the ingredients right is essential to achieving the perfect balance of textures and flavors in this recipe. Each component plays an important role—whether it’s adding sweetness, crunch, or that rich golden finish that makes your vegetables irresistible.

2 medium bell peppers: Red, yellow, or orange peppers add sweetness and vibrant color to the mix.
2 medium zucchini: Trimmed and cut into half-inch pieces, they provide a tender, mildly sweet texture.
1 small sweet potato: Cut into three-quarter-inch pieces, it brings a lovely natural sweetness and a tender bite once roasted.
1 small red onion: Cut into one-inch cubes, it adds a subtle sharpness that mellows beautifully when roasted.
1 small head of broccoli: Cut into florets, or swap with cauliflower or trimmed Brussels sprouts for a twist.
3 tablespoons extra virgin olive oil: Key for coating and bringing out the natural sweetness while ensuring crisp roasting.
1 tablespoon Dijon mustard: Adds a tangy depth; replace with olive oil if you prefer a milder profile.
2 teaspoons Italian seasoning: A fragrant blend that infuses herbal notes throughout.
1 teaspoon kosher salt: Enhances flavors without overpowering.
1/2 teaspoon garlic powder: Introduces a subtle garlic warmth that complements every vegetable.
1/2 teaspoon ground black pepper: Adds a faint kick and balances the seasoning.
3 tablespoons grated Parmesan cheese (optional): Sprinkled on top for a nutty, savory finish once roasting is complete.

How to Make Oven Roasted Vegetables Recipe

Step 1: Preheat and Prepare Your Oven

To start your Oven Roasted Vegetables Recipe on the right foot, preheat the oven to a warm 400 degrees Fahrenheit. Position your racks so you have one in the upper third and another in the lower third if you plan to roast on two baking sheets. This setup helps ensure even roasting with those golden, crispy edges we all love.

Step 2: Season the Vegetables

Place your prepared vegetables into a large bowl or divide them directly on two rimmed baking sheets. Add the extra virgin olive oil and Dijon mustard, which work magic by helping the seasonings adhere while enhancing flavor. Sprinkle Italian seasoning, kosher salt, garlic powder, and black pepper over everything. Then, lovingly toss to coat every piece, paying extra attention to the broccoli florets since they can burn if left dry.

Step 3: Spread and Roast

Spread the vegetables evenly in a single layer on the baking sheets. This gives them space to roast evenly and develop that perfect crispness without steaming. Roast them in the preheated oven for 25 to 35 minutes, or if your oven offers convection, try 375 degrees for 20 to 25 minutes. Remember to toss the veggies, rotate the pans 180 degrees, and swap their positions midway for consistent cooking.

Step 4: Final Touch and Enjoy

Once the vegetables are tender inside with deliciously browned, crispy edges, remove them from the oven. While hot, sprinkle the grated Parmesan cheese on top if you like, which melts slightly and adds a savory layer to the dish. Your Oven Roasted Vegetables Recipe is ready to serve right away, warm or at room temperature.

Creative Ways to Present

Try serving your Oven Roasted Vegetables Recipe on a rustic wooden board with toasted bread and dips like hummus or tzatziki. You can also blend leftovers into creamy soups or chop them to add texture and color to frittatas or omelets.

Make Ahead and Storage

Storing Leftovers

Place any leftover roasted vegetables in an airtight container and refrigerate for up to 4 days. They remain flavorful and can be easily reheated or repurposed into other meals during the week.

Freezing

While roasting is best enjoyed fresh, you can freeze cooled veggies by spreading them in a single layer on a baking sheet first, then transferring to freezer bags once frozen solid. Use within 2 months for best flavor and texture when reheated.

Reheating

Reheat your Oven Roasted Vegetables Recipe in a preheated oven at 350 degrees Fahrenheit for about 10 minutes, or until warmed through and crisp again. Avoid microwaving if you want to maintain their roasted texture.
