Perfect Roasted Veggies: Chef Tested Recipe!

In culinary school, we were taught to roast each type of vegetable on its own separate sheet pan. While this is practical in a food service setting for a larger volume of veggies, at home it’s not so. The following test kitchen tried and approved technique of roasting vegetables all together works well as long as you cut the veggies accordingly. Read on for more tips on how to get perfect results!

Why We Love Oven Roasted Vegetables:

  • You can use a blend of vegetables!
  • The veggies cook on one sheet pan, and they are done at the same time.
  • They can be customized with all sorts of seasonings
  • They can be prepped ahead for meal prep and reheat well!
  • They are hands-off! They’re a prep ’em and forget ’em kind of a recipe that requires very little babysitting!

What you’ll need to make Roasted Vegetables in Oven

Here’s one list of the combinations of vegetables you can roast. Keep in mind, you can swap these veggies out for your favorites or whatever you have on hand. I have also tested this with other vegetables. Full measurements are in the recipe card below.

  • Carrots: Peel your carrots and cut them into 1/3-inch slices. 
  • Bell Peppers: Cut them into large dice, or swap them for delicata squash, seeded and cut into half moons. seeded and cut into half-moons
  • Broccoli: Cut the broccoli crown (or cauliflower) into florets.
  • Zucchini: Cut your zucchini into 1-inch chunks, or halve Brussels sprouts instead. 
  • Olive Oil: Use extra virgin olive oil or something neutral like avocado oil.
  • Seasonings: Dried Italian herb blend, Kosher salt, and black pepper. 

Pro Tip For Cutting Veggies for Roasting:

  • Hard Vs Soft: Some veggies cook faster than others. In general, those that are hard (like carrot, parsnips, celery root, beets or butternut squash) will take longer to soften than those that are higher in water content and softer like like bell pepper, green beans, asparagus, summer squash or zucchini.
  • Cut Size: Cut the veggies smaller if they are hard and larger if they are soft
  • Onions and Brassicas: Any color of onion (red, yellow, sweet or white) and cauliflower, broccoli and Brussels sprouts will cook at an intermediate rate – so cut them into bite-size uniform pieces. 

How to Roast Vegetables

Step 1: Preheat

Preheat the oven to 425 degrees F. 

Step 2: Season Veggies

Toss the chopped veggies, oil, herbs, salt and pepper in a large bowl to coat them.

Step 3: Add Vegetables to Sheet Pan

Spread the seasoned veggies in a single layer onto a large, rimmed baking sheet. You can line the baking sheet with parchment paper or aluminum foil for easier cleanup here.

Spacing: It’s important to roast the veggies in an even layer so that they do not overcrowd the pan. They will brown better and cook more evenly this way.

Step 4: Roast Veggies

Transfer to the oven and roast, stirring once or twice, until browned and tender inside when tested with a fork, 30 to 37 minutes (see note.) Serve hot or warm.

What if they aren’t all done at the same time?

This happens sometimes, and don’t worry! Sometimes the softer veggies are starting to dry up or shrivel a bit while the harder veggies are not quite fork-tender. There’s an easy fix!

  1. Simply scrape the veggies into a large baking dish (like a 9 by 13 lasagna pan) and cover with foil.
  2. Pop them back into the oven and roast for another 10 minutes or so.
  3. This will prevent too much additional browning, but give the veg more time to soften.

Roasted Veggies Recipe Tips

Natural Sugars: Veggies with natural sweetness (like carrots, peppers, sweet potatoes and onions) have naturally occurring sugars that darken more quickly than other veggies. While cutting the veggies according to our suggestions will usually ensure all the veggies will be done together it is important to use your cooks intuition and keep an eye on your pan of veggies. If your batch is getting too dark, they’re probably done no matter what the timer says! If yours are too dark before they soften through, cover with foil and reduce the oven temperature to 350 degrees.

Spices: If improvising with seasonings, note that dried herbs can be added to the vegetables in step two. However, we have found that some dry spices, like garlic powder, are better when added later in the roasting. Sprinkle it on in the last 10 minutes of roasting and give a good toss. This will prevent the spices from being scorched.

Using a Convection Oven: Not all ovens have a convection setting. If yours does, feel free to use it. This will circulate the hot air and cook the veggies evenly and quickly. Note it is important to modify the recipe and lower the oven temperature to 400 on the convection setting. Keep an eye on the veg for the last 5 minutes or so and make sure they are not too dark.

Oven Roasted Vegetables Variations & Substitutions

  • Try different seasonings for a variety of flavor profiles. If you like a little spice, add some chili powder or red pepper flakes
  • If you’re pairing this dish with something like butter chicken, try adding some curry powder to your veggies. 
  • More simple seasonings include garlic cloves and fresh herbs, like fresh rosemary
  • Add a drizzle of vinegar, lemon or balsamic vinegar glaze for a hint of acidity. 
  • Parmesan cheese or nutritional yeast is a great way to add a cheesy layer to this side dish. 
  • Soy Sauce would be great over these vegetables – just be mindful of how much salt you add. 
  • Us any different vegetables that you have on hand, or personally love. We love green beans, turnips, sweet potatoes, red potatoes, onions, and more!  

What to Do with Mixed Roasted Vegetables

Here are some options for what to serve with oven-baked vegetables.

  • Pizza: Freestyle a homemade pizza. Start with our whole wheat pizza dough with a base of pesto, alfredo sauce or marinara and then top with the roasted veggies, mozzarella cheese and or goat cheese. Top with toasted pine nuts once it comes out of the oven.
  • Eggs: I keep them on hand to add veggies to my breakfast too. I’ll either make a roasted veggie breakfast scramble, add to a breakfast pita, breakfast burrito or add to a frittata like our frittata with ham and asparagus.
  • Grain Salad: Add them to a grain salad. For example, our Roasted Sweet Potato Brown Rice Salad would work- just use these veggies instead of the sweets!
  • Seafood: In the summertime, we love a seafood feast. I’ll make steamed lobsters and boiled potatoes. Then I’ll do up a mass of summer roasted vegetables (including red bell peppers, eggplant, zucchini, and corn cut off the cob) I’ll season the veg with Old Bay seasoning instead of the Italian seasonings. It’s an amazing combo! We also love it with Pan Fried Fish and other stovetop seafood recipes.
  • Salad: For lunch I’ll top my salad with leftover roasted veggies, chicken and drizzle with whatever salad dressing I have on hand for the week.
  • Chicken: Serve with classics like chicken. Make a roast chicken, then while the chicken rests, pop these veggies into the oven.
  • Beef: Pair with pan-cooked steak, like our Filet Mignon recipe, or other stovetop beef dishes.
  • Pork: Choose a pan cooked pork chop recipe so the oven can be used for the veg.

Make Ahead, Storage, and Reheating Instructions for this Roasted Veggies Recipe

  • Make Ahead: To prep this recipe, chop the vegetables ahead of time.
  • Leftovers + Storage: Store any leftovers in an airtight container for up to 5 days in the refrigerator.

Roasted Vegetables Recipe FAQs

What is the best temperature to roast vegetables in the oven?

The temperature we recommend to best roast vegetables in the oven is 425 degrees Fahrenheit. The veggies benefit from high temperatures. While it is possible to roast veggies in a hotter oven, like 450 degrees F, we are not recommending it for mixed roast veggies. When blending together soft and hard veggies (and those with a high sugar content) it is a safer bet to opt for 425 so the vegetables do not burn. Use the oven rack in the middle of the oven as the bottom of the oven is often too hot and the bottom of the veggies (where they touch the pan) will scorch.

How long do they take?

Time your veggies depending on what combination you choose. Softer veggies like peppers, broccoli and zucchini will be ready at around 30 minutes, while dense vegetables like delicata squash and brussels sprouts will take a little longer (35 minutes or so.)

What is the best pan to use to roast vegetables in the oven?

Any sheet pan or baking sheet is good for roasting vegetables in the oven, but you want to make sure it’s large enough that you can spread the veggies out in one layer without being too crowded. We do not recommend a dark rosting pan or baking sheet. If you’re making more veggies, use two sheets or bake them in turns.

What veggies are best for roasting?

So many veggies lend themselves to oven-roasting! Root vegetables, cruciferous veggies, bell peppers, red onion, and even some soft vegetables are great when roasted. You can even add in leafy greens (prepped with a coating of oil, salt and pepper) in the last five minutes. It’ll char up a little bit and wilt down with the other veggies.

If you are roasting mostly soft veggies but want to add in slower cooking vegetable you can cook them in sages like the roast veg recipe I developed for Eating Well. Simply give the harder veggie a head start, then stir the remaining vegetables in and continue roasting.

Should vegetables be roasted on parchment paper?

In culinary school, we were taught to roast vegetables directly on the sheet pan. You can add a layer of parchment but it will slightly reduce the amount of browning. Opt for parchment paper to reduce clean-up.
