Roast Vegetables

Looking for a vegetable side dish that's simple, tasty, and cheap to make? Look no further.

Roast Vegetables are it. It takes very little work, tastes great, and best yet:you can make it with whatever vegetables you have on hand!

My friend Jessika (with a K) gets the credit for this recipe. She showed me how to make veggies so my people would like them.

Why Make This

It's one of the best ways to cook vegetables. Roasting vegetables in olive oil and garlic gives them a delicious depth of flavor and caramelization that's just out of this world.

It's super easy. This recipe is amazingly easy to prepare and uses virtually any vegetables you have on hand.

It's so darn good! I really can't say enough good things about this dish. I cooked it up after lunch one day so that I could take pictures. I left it on the counter, and my people devoured it. As a snack. 'Nuf said?

Here's what you'll need to roast vegetables in the oven:

vegetables – You can use any of your favorite vegetables, including:

onions, leeks, or shallots
garlic, sliced
mushrooms, quartered or sliced
green beans
edible pea pods, like sugar snap or snow
carrots, baby or whole carrots cut into chunks, strips, or chips
eggplant, sliced or cubed
zucchini or yellow squash, sliced
winter squash, peeled and cubed
tomatoes, grape or roma cut into chunks
peppers, hot or sweet, cut into chunks
broccoli or cauliflower, cut into florets
celery, cut into chunks
asparagus, cut into chunks
potatoes, sweet or white, cut into chunks

Any vegetable that you love for cooking is a great candidate for roasting.

oil – I use olive oil, but you can use your favorite cooking oil.

spices and herbs – Use whatever herbs and spices you like. There are so many Spice Mixes to choose from such as Homemade Seasoned Salt or Italian Seasoning Mix.

Step-by-Step Instructions

Preheat the oven to 400°. Spray a glass, 9×13-inch pan with nonstick cooking spray or line a baking dish with parchment paper.
In a large mixing bowl, combine the vegetables with the olive oil, salt, pepper, and herbs.
Transfer the vegetables to the prepared pan and roast for 30 to 45 minutes, until the vegetables are tender and slightly browned on the edges. (The timing will differ depending on what kinds of vegetables you use. If you just use broccoli, it will be done in a much shorter time than potatoes.)

Tips for Success

Slice evenly. Even sized cuts will make sure they roast evenly in the oven.
Group veggies by cooking time. Not all veggies will roast the same time. Cruciferous veggies (like brussel sprouts, broccoli, and cauliflower) will take less time (like 20-25 minutes) than your root veggies (like carrots, potatoes, parsnips, and turnips), about 30-45 minutes.
Use a high heat. We find that 400°F is the perfect oven roasting temperature.
Season well. Make sure to season your veggies well and before you cook them for the best flavor.

FAQs

Can I roast vegetables in a toaster oven?

Oven roasting does involve heating the oven. This is fine in the cooler months, but you may hesitate to do so in summer, even though there are so many great veggies for roasting then.

If you have a toaster oven, you may be able to swing this without turning on the big oven. Another alternative is to do the roasting in the morning or late at night when the temps are cooler.

What can I serve roasted vegetables with?

Roasted vegetables are delicious hot, cold, or at room temperature. They are delicious on their own, alongside grilled or roasted meats, and in bowl meals.

What temperature is best for roasting vegetables?

High temperatures are best to roast vegetables, from between 375 to 450 degrees.
