How to Make Delicious Oven Roasted Vegetables
Here are my best tips on how to make oven roasted vegetables that are absolutely delicious every single time!

What temperature is best for make oven roasted vegetables?
Essential tools for roasting vegetables.
There are some essential tools that every cook needs in making oven roasted vegetables easily and with the best results. Below is a list of what you need and also a link to my favorite brands and products.
- Extra Large Baking Sheet. Vegetables that are crowded on a baking sheet will steam rather than roast. I have two USA extra-large baking sheets that I use and love. Nordic Ware also has a good jumbo baking sheet that works well.
- Fish spatula. A thin, flexible spatula helps easily turn large amounts of vegetables at one time. I LOVE this OXO fish spatula and have two. They are my go-to spatulas for everything~not just fish.
- Kosher salt. Good kosher salt is essential in roasting vegetables. The 2 best brands are Diamond Crystal and Morton kosher salt. Do not use table salt for roasting vegetables. It will make them overly salted and metallic tasting.
- Extra virgin olive oil. My favorite is Colavita. Costco has one good EVOO but it is in and out of stock.
How to roast fresh vegetables.

When I refer to fresh vegetables, I mean Brussels sprouts, zucchini, summer squash, onions, cauliflower, and bell peppers. Almost every night of the week, I’ll roast these fresh vegetables in the oven for dinner. These vegetables encompass the “red, yellow & green” part of our daily diets. Root vegetables are also wonderful, but they are in a different category. I talk about them below. Below are my tips for roasting fresh vegetables.
Tips for roasting fresh vegetables.
- Heat your oven to 425 degrees F. This is the temperature that works best, as it compensates for the drop in temperature when the oven door opens.
- Toss the vegetables with good extra virgin olive oil and seasonings. Kosher salt + ground pepper are essential seasonings.
- Use your hands to massage vegetables with EVOO, salt & pepper. Your hands are the best tool to massage the oil & seasonings into the vegetables so that they are completely coated.
- Use an extra-large baking sheet. This ensures that the vegetables roast (rather than steam).
- Stir the vegetables halfway through and rotate the baking sheet. This will ensure even browning.
How to add flavor to oven roasted vegetables.
In the short video below, I share a few tips about how to add flavor to roasted vegetables. I share the “essentials” for giving roasted vegetables good flavor, along with some other seasonings that I love to use as well.
How to reheat leftover oven roasted vegetables.
Heat leftover roasted vegetables in the oven so that they will be firm and crisp. A microwave will make them soft and nothing like the original roasted version. Reheat roasted vegetables by spreading them on a baking sheet, spraying them with EVOO, and baking them at 425 until heated and crisped. Since I have a Breville Smart Oven Air, I air fry mine at the same temperature on the air fry setting.
How to roast root vegetables.

When Fall arrives, root vegetables are in season. If you’ve never roasted root vegetables, you don’t know what you are missing!!!! This technique will work with any root vegetables, so you can choose the combination that works for you, whether it be carrots, parsnips, sweet potatoes, beets, or turnips. Celery root and rutabagas also work well. The secret to cooking a variety of vegetables simultaneously lies in the cutting. Be sure to cut the vegetables into uniform sizes. This will ensure that they cook and brown evenly.

THREE BEEF TENDERLOIN RECIPES + SIDES AND DESSERTS TO GO WITH THEM
Hi Cindy!!!! Great questions!!! I add the spices after coating the steaks with EVOO. Do a light dusting so that the steaks get flavored but not “powdery.” Once I overdid the curry/turmeric and that happened.
I would present them on a platter for the company. But for family, I serve off the sheet pan!!!! Hope y’all enjoy!!!
Hey, I have 2,questions. One is on the cauliflower steaks do you add the turmeric and curry before or after you roast the steaks?
The second is how is the best way to serve the roasted vegetables? Straight off the sheet pan?
If I am serving them for company is there a way to serve them in a pretty bowl while they still stay hot and fresh?
Thank you for these recipes!
Oh mercy!!! That is a problem lol!!! Why don’t you try 400 F and put the rack in the upper (not directly under the coils but higher than midway). You can also cut your veggies into smaller chunks so that they cook more quickly on lower heat. Let me know if this works!!!!
I am at a loss! We are in a new house with smoke alarms that are sensitive and connected to our home security system (new at having an alarm system). We also have a gas stove (first time). Every time I have roasted vegetables at 425 degrees, my smoke alarm goes off causing total chaos. I am hesitant to roast vegetables now, but love them. My niece who lives with us as she attends Pharmacy School roasted sweet potato chunks yesterday at 400 degrees. They were crispy on the outside and cooked in the middle. I am wondering if my vegetables would be just as good at a lower temperature just to keep my sanity. Perhaps my oven is a little hotter than my 20 year old electric one.
