Roasting vegetables is a fantastic way to prepare them, offering a delightful alternative to steaming or boiling. The process is simple, requires minimal effort, and results in vegetables with intense flavors and crispy edges that even the pickiest eaters will love. Here's a step-by-step guide to achieving perfectly roasted veggies every time.
What Vegetables Can You Roast?
Root vegetables such as potatoes, parsnips, sweet potatoes, and carrots are classic choices. However, don't limit yourself! Dig through your crisper drawer and you'll find plenty of candidates for roasting, from crucifers like broccoli and Brussels sprouts to surprises like zucchini, onions, bell peppers, and even tomatoes.
Step-by-Step Roasting Guide

Step 1: Prep Your Veggies
Preheat your oven to 425°F (220°C). Peel and chop your selected vegetables into bite-sized cubes or long sticks. Uniformity in size ensures even cooking.
Step 2: Coat with Oil
Toss your chopped veggies with a good-quality oil. Olive oil is versatile for most vegetables, but for an extra touch, consider using goose or duck fat for potatoes. Avocado oil or coconut oil also work well. Use just enough oil to coat the vegetables evenly—usually a couple of tablespoons.
Step 3: Season Well
Sprinkle salt and pepper over the oiled veggies. Feel free to add other spices and herbs according to your taste.
Step 4: Spread Out the Veggies
Arrange the vegetables in a single layer on a baking sheet, ensuring they have space between them. Overcrowding leads to steaming rather than roasting, resulting in soggy vegetables. If needed, use two baking sheets.
Step 5: Roast Until Perfect
Roast the vegetables until they are tender and have crispy edges. Smaller pieces will take around 15-20 minutes, while larger pieces, like chunks of potatoes, may need up to 50 minutes. Stir the vegetables halfway through the roasting time to ensure even crisping.

Secrets to Extra Crispy Roasted Vegetables
To achieve extra crispy vegetables, it's crucial to spread them out in a single layer on the baking sheet, avoiding overcrowding. This allows hot air to circulate around each piece, ensuring even roasting and preventing steaming, which can lead to soggy results. Maintaining a high oven temperature, ideally around 425°F, is essential for most vegetables to achieve that perfect crispiness. For an extra touch of crispiness, consider increasing the temperature to 450°F for the last 5-10 minutes of roasting. Always roast vegetables uncovered, as covering them traps steam and results in a mushy texture. Uncovered roasting facilitates proper air circulation, contributing to the desirable crispy edges that enhance both the flavor and texture of the vegetables.
What Vegetables Can Be Roasted Together?
When roasting vegetables, it's important to pair those with similar cooking times on the same baking sheet to ensure even cooking. For example, carrots and parsnips, or broccoli and cauliflower, roast well together as they require similar durations. However, for vegetables with varying cooking times, such as potatoes and bell peppers, it's best to use separate baking sheets or add them to the oven at different times. This approach allows each vegetable to cook at its optimal pace, preventing overcooking or undercooking.

Some Additional Tips for Perfectly Roast Vegetables
When dealing with vegetables that have different cooking times, it's often best to roast them on separate trays. This way, you can monitor each type individually and remove them from the oven as soon as they reach the desired level of doneness. Once all the vegetables are cooked, you can combine them for serving. Moreover, it's essential to check the vegetables midway through the roasting process. This allows you to adjust the oven temperature or rearrange the trays if necessary, ensuring that each vegetable roasts evenly and achieves the perfect texture.
