  5. Finish the roasted veggies with a squeeze of fresh citrus and a drizzle of vinaigrette. Add a pinch of red pepper flakes for heat.

How To Roast Vegetables

Prep the Vegetables

Peel or scrub any veggies needing it, wash, then thoroughly dry with a towel to remove any excess moisture. This helps them brown rather than steam.

Toss with Oil and Seasonings

Add the veggies to a large bowl along with olive oil, salt, pepper and any other seasonings. Toss with your hands until fully coated. It’s okay to get your hands a little dirty!

Roasting Time

Trust your intuition on roast times as they can vary slightly based on veggie size, actual oven temperature and type. Watch veggies closely and check for fork-tenderness and crispy, caramelized exteriors when done.

Almost Done

Once veggies are done roasting, taste and season further if needed, adding a pinch more salt or grinds of pepper to bring out maximum flavor.

Serve and Enjoy! The roasted veggies are now ready to serve while still hot and devour their delicious flavors.

How Long To Roast Vegetables 

Step 1: My favorite blend includes potatoes, red onion, Brussels sprouts, and carrots. Roasting them together works well since they have similar cook times. Cut to similar sizes also helps them cook evenly.

Step 2: Harder, denser veggies like sweet potatoes, parsnips, butternut squash, and beets roast nicely in 35-45 minutes. Brussels sprouts and carrots also fall in this timing range.

Step 3: Softer veggies on the other hand, such as zucchini, bell peppers, sweet corn, and summer squash, need only 15-20 minutes in the oven.

Step 4: More delicate veggies like thin asparagus or green beans may only require 10-20 minutes depending on thickness.

Step 5: When roasting a combination of hard and soft veggies, stagger the roast times. Add quicker-cooking veggies to denser veggies halfway through or leave room to add them in later once space frees up on the pan.


1- Winter Veggies

In winter, try roasting sweet potatoes alongside Brussels sprouts and parsnips for a hearty mix.

2- Spring Veggies

Asparagus and fennel are delicious roasted veggies in spring.

3- Summer Veggies

In summer, roasted cherry tomatoes, zucchini, bell peppers and summer squash are vibrant options.

4- Fall Veggies

For fall, cauliflower florets, broccoli and carrots are wonderful roasted.

5- Spice Options

Play with different spices like thyme, rosemary, Italian seasoning or Herbs de Provence.

6- Blend Your Spices

Try blending spices like cumin, coriander and garlic powder or curry powder for added flavor.

7- Sauces and Garnishes

Drizzle roasted veggies with Honey Jalapeño Lime Vinaigrette or top with a spoonful of Creamy Dill Sauce. Garnish with fresh herbs like basil, parsley or cilantro.

How to Store

Refrigerator: Leftover roasted vegetables can be stored in an airtight container in the fridge for 3 to 4 days.

Freezer: For longer storage, cool fully then transfer roasted veggies to an airtight resealable plastic bag or silicone storage bag. Freeze for up to 3 months. Veggies maintain texture well when frozen. Consider adding some to soup or stew.

Reheating: To serve again, place frozen veggies in a single layer on a baking sheet and warm through in a 400°F (204°C) oven until hot. Or place a serving in a microwave-safe bowl and microwave in 30 second intervals until warmed through.

Storing roasted vegetables properly in the fridge or freezer helps you enjoy the leftovers for several days while maintaining the delicious texture and flavor from the initial cooking process.

7: Are Roasted Vegetables still healthy?

While heating causes some nutrients to be destroyed, roasted veggies retain many of their antioxidants when cooked in heart-healthy olive oil and seasonings. They remain a nutritious addition to any meal.

Seasoning the veggies before roasting helps the flavors develop further with the help of heat. An additional taste test and seasoning once roasted may be needed.

9: How long does it take to roast vegetables at 400 ?

A vegetable blend will typically roast at 400°F (204°C) for 35-40 minutes but timing depends on factors like oven temperature. Leave plenty of room for airflow so they don’t roast overlapping and end up steaming.

The middle rack position is best for even baking and roasting of vegetables. This allows heat to circulate properly.

11: Can you roast frozen vegetables?

While roasting frozen veggies won’t yield results as close to fresh, it’s still a great option when convenience is needed. They may not caramelize as well but can still turn out tasty. Too much liquid in frozen needs to steam off first.

Roasting in a single layer on a baking sheet with space between pieces allows hot air to circulate and vegetables to brown and crisp up without steaming. Oil is necessary for caramelization versus steaming.

This French herb blend typically contains rosemary, thyme, savory, and lavender – herbs that pair beautifully with everything from potatoes and zucchini to brussels sprouts and carrots. A light sprinkling of herb de Provence over vegetables before roasting infuses them with woodsy notes and a subtle flowery aroma. Another easy herbcombo is Italian seasoning, a robust blend of oregano, basil, rosemary and sometimes marjoram or garlic. These dried herb blends require minimum preparation and effort but maximum flavor impact. No matter the blend used, finish roasted veggies with a touch of olive oil, sea salt, and cracked black pepper for balanced yet bold flavor.
