Why Rainbow Vegetables Make for a Healthy Plate

Studies show it’s important to eat a variety of color-rich vegetables because the nutrients responsible for each color have different protective properties. For example, red foods, like tomatoes, contain antioxidants like lycopene. Orange foods, like carrots, are high in carotenoids, including alpha-carotene and beta-carotene.

So, if you’re looking to fight disease and free radical damage, include this rainbow roasted vegetables recipe on regular rotation. Here’s a little bit more about each vegetable included:

Peppers: Bell peppers are an excellent source of vitamin A, vitamin C, and potassium. They also contain a healthy dose of fiber, folate, and iron.

Carrots: Carrots are a particularly good source of beta carotene, fiber, vitamin K1, potassium. They also contain carotenoids and antioxidants.

Zucchini: Zucchini is a great source of vitamin C, and also contains vitamin b6, riboflavin, and manganese.

Broccoli: Broccoli is a nutrient powerhouse! It’s rich in fiber, vitamin C, vitamin K, iron, and potassium. It also has magnesium! It’s also a cruciferous vegetable that helps support estrogen and hormone metabolism.

Onions: Onions are a great way to support gut health, as they are one of the only foods rich in prebiotics (what help support and feed probiotics). They also contain antioxidants, flavonoids, vitamin C, folate, vitamin B6, and potassium.

How to Make Sheet Pan Rainbow Roasted Vegetables

Making sheet pan rainbow roasted vegetables couldn’t be easier!

First, cut your vegetables into 1-inch slices or cubes. If you’re new to sheet pan roasted vegetables, this is the most important thing to remember when it comes sheet pan dishes. In order for the vegetables to all cook evenly, everything needs to be sliced and cut into the exact same size. In this recipe, all vegetable peices should be about 1-inch in size.

Arrange your vegetables on your sheet pan following the color of the rainbow—red peppers, orange carrots, yellow peppers, green zucchini and broccoli, and purple onions. Pour the coconut oil over your vegeatbles, and season with the garlic, Itailian seasoning, salt, and pepper.

Roast the vegetables until tender, about 20-25 minutes.

Remove the vegetables from the oven and drizzle the roasted vegetables with lemon juice directly on the pan before serving.

Making Vegetable Swaps

You can customize this recipe so that it includes a variety of vegetables. Depending on the time of year, consider swapping the veggies for whatever is in season. You can easily tell this by noting what’s on sale at the grocery store, or by shopping at a local farmer’s market.

Thus far, I’ve swapped in zucchini for asparagus pieces, diced butternut squash for yellow pepper, and I’ve used purple and orange sweet potatoes. When you’re swapping in other vegetables, be sure they are equal in size to the other vegetables on the tray, especially when doing potatoes and squashes.
