Roasted vegetables are vegetables cut into roughly even pieces, tossed with olive oil and salt, and cooked at high heat (typically 425 to 450 degrees) until the edges caramelize and the centers turn tender. It's the easiest way to make any vegetable taste 100 times better than it does raw or steamed. I roast something at least three times a week as part of lunch or dinner, and this is the bookmark page for every variety I've tested. If you want a single-vegetable deep dive, my Crispy Lemon Roasted Brussels Sprouts are the canonical proof of concept; for a flavor-forward riff, my Cacio e Pepe Roasted Potatoes apply the same high-heat technique to spuds. And if you're staring down a holiday spread, my Complete Guide to Thanksgiving Side Dishes leans on this technique constantly.

First let's start with general rules:
1. High heat! Make sure your oven is at 425-450 degrees F! And it doesn't hurt to get a cheap internal oven thermometer to make sure your oven is running properly! Trust me - it's the best $7 you'll spend.
2. Space. You can't crowd a bazillion chopped vegetables on one baking sheet. They need to have room to breathe and really roast and develop flavor.
3. Olive Oil. Toss the vegetables in olive oil before starting. Just enough, you don't need to douse them and you don't need to skimp, but enough to evenly and lightly coat the veggies. I usually do 3 tablespoons per pound of vegetables.
4. Uniformed size! If you're roasting multiple veggies at the same time, make sure you cut them into the same sized pieces so they can roast evenly.
5. Seasonings. Before I throw anything into the oven it gets a healthy dose of kosher salt, freshly cracked black pepper, some red pepper flakes and one of my favorite seasoning blends. When they are done roasting, I usually hit it with some freshly squeezed lemon juice to give it a touch of acid and really pump up the flavors. It's great on Brussels Sprouts, Broccolini and Cauliflower!
6. Timing. Roast the veggies, uncovered, for at least 20 minutes before peeking into the oven. After 20 minutes, remove the baking sheet, give the veggies a quick toss to ensure even roasting, and place the baking sheet back into the oven to finish off for 5, 10 or 15 minutes. You're looking for golden brown edges because that's where the flavor really develops!
7. Perfection. Perfectly roasted vegetables will be slightly crispy and brown around the edges and perfectly cooked in the middle. That's what is going to give it the best flavor.
8. Location. Heat rises, so roast vegetables on the top baking rack in your oven!
9. Grouping. If you're going to roast multiple kinds of veggies on the same baking sheet, make sure you combine them in groups that make sense. For example it doesn't make sense to roast broccoli and potatoes together since they have such different cooking times. Here are the groups I like to mix together:
- Carrots + Broccolini
- Baby Potatoes + Squash
- Onions + Brussels sprouts
- Cauliflower + Broccoli
- Zucchini + Bell Peppers + Eggplant
- Asparagus + Leeks
10. Parchment - roasting can sometimes make your pans a little dirty and tough to clean, so I ALWAYS roast on parchment. I keep the pre-measured sheets on hand at all times and they are the best!
Okay! Below you'll find the guidelines for the 10 vegetables we're starting with! More added soon 🙂 Prepare to up your veggie game - you'll never make them any other way again.
Carrots
As a general rule for carrots - I like to buy on the small side. Nothing too fat, and if that's all there is, slice them in half of quarters lengthwise. Baby carrots are my favorite - and yes, I like to keep a little bit of the stem on when roasting. It's delicious - you should try it! 450 degrees for approx 30-35 minutes will result in the texture that is pictured below! These are seasoned with my Meat seasoning which is actually epic even not on meat.
Broccolini
Not exaggerating, I make this at least 4 times a week and we eat it by the bucket. 450 degrees (per usual) for 20ish minutes until the florets are a bit crispy. I use Gaby’s Everyday on my broccolini every single time for perfect results!
Cauliflower!
There's nothing worse than sad Cauliflower! Amp yours up with a sprinkle of Meat and then pop it in at 450 degrees for about 25-30 minutes. You REALLY want the brown bits to shine on this one - don't take it out until it's really a deep golden color.
Sweet Potatoes
Most people will tell you it takes 20 minutes to make sweet potatoes, I disagree. I think it takes 30. Dice them up into about ½ - ¾ inch cubes and toss them with olive oil. These are great seasoned with just salt and pepper - or I use Meat on the ones pictured below.
Mushrooms
Be sure to give mushrooms plenty of room to breathe when you're roasting. These are crimini's pictured below - but same principle applies for all mushrooms. I cut them in half, leaving them stem and coat them with plenty of olive oil. A sprinkle of Gaby’s Everyday and then into the 450 degree oven they go. Mushrooms give off quite a bit of liquid so they need time to roast and for that liquid to evaporate! 25-30 minutes until golden brown. And make sure to toss them for even roasting!
Brussels Sprouts!
My favorite! Depending on the size, you should either cut them in half or quarters. The ones below were BIG Brussels, so I quartered them because you want them to get as golden and crispy as possible - trust me - they'll basically turn into candy. Gaby’s Everyday goes on top with some olive oil and into the oven they go. 25-30 minutes should do the trick and then add some fresh lemon juice on top!
Butternut Squash
I keep roasted squash on hand AT ALL TIMES. You never know when you want to whip up a quick soup and having roasted squash takes some of the prep work out of the equation. Lemon Pepper is EPIC on these and goes on top with some olive oil and into the oven they go. 30ish minutes should do the trick and you want a little bit of caramelized color on some of the squash.
Delicata Squash
If you've never made Delicata Squash before - get ready. This is my fav squash to roast because you don't actually have to take the skin off. The delicata skin softens right up in the oven and it's delish. Lemon Pepper is EPIC on these too as is Gaby's Everyday! They only need about 20-25 minutes to roast with some olive oil at 425/450 degrees.
Eggplant
ONE OF MY FAVS!! My papa used to make eggplant dishes all the time and roasted eggplant will forever remind me of him. He used to puree it into a dip and everything about it is amazing (the dip recipe is in my Eat What You Want Cookbook FYI) But today it's just roasted for the perfect easy side dish or addition to a salad. 425 with any of your fav seasonings for 30-40 minutes. Also keep in mind, eggplant needs a decent amount of oil so don't be afraid to really coat it in olive oil before adding the seasoning and roasting.
Onions
Roasted onions are the quickest way to make your house smell like heaven! I roast onions before dinner parties during the holidays so everything smells amazing by the time the guests arrive! I like them to have a decent amount of color so aim for 30-40 minutes and then use them alongside a roasted chicken, add them to salads, turn them into an onion dip! Have at it!
AND WHATEVER YOU DO - Keep your eyes on the veggies!! Every oven is different so make sure you keep your eyes on them and take them out when they look like the above pictures
Is it ok roast veggies in an air fryer
sure! an air fryer is just a small oven on convection bake!
I roast veggies from my Fresh Produce Box on the regular, at least twice a week. They are good in so many things and I could eat the whole pan sometimes all by myself.
Thank you for the other recipes!
Do you ever have issue with the veggies sticking to parchment? My pans get so dirty but I prefer that to leaving behind veggies on parchment. Am I not using enough oil?
I use parchment all the time - and no nothing sticks!! But if you ditch the parchment, just make sure there is plenty of oil and you toss everything to evenly coat before roasting!
Love this! I agree roasted veggies are the way to go. Wish you could somehow make a printable chart with each vegetable and the specific seasoning. Maybe just include the general rules at the top or bottom. Congratulations on baby Poppy!
