Best Blue Vegetables

1. Blue Bayou Tomatoes

This gorgeous tomato has skin that ranges in hue from deep navy blue to purple. Blue Bayou Tomatoes are utilized as a vegetable even though they are considered a fruit. It is produced on strong stems.

Blue Bayou Tomatoes have a sweet and fruity taste. They are often used in salads. And, although tomatoes are technically a fruit, I’ve included them on this list of the best blue veggies simply because most people consume tomatoes as a savory vegetable.

2. Blue Cabbage

Red cabbage or purple cabbage has a milder, sweeter flavor than other varieties of cabbage. Cooking the cabbage in an alkaline liquid causes the component that gives it its red color to turn blue.

This cabbage is rich in nutrients, may help fight inflammation, may enhance gut health, and has many other health benefits.

Blue Cabbage is typically prepared as a side dish. It can be cooked with butter, onion, green apples, bay leaves, cloves, peppercorns, red wine, and more. Try making Air Fryer Cabbage!

These vegetables are abundant in anthocyanins and beta carotene, which have been shown to boost memory and vision. They also have all the health benefits of regular orange carrots.

For a quick gourmet-looking snack, roast them and serve them with dip. You could also try making Air Fryer Carrots or Instant Pot Carrots for a quick and easy side dish.

4. Blue Corn

Blue Corn is grown in Mexico, the Southwestern United States, and the Southeastern United States. It is one of the main varieties of maize used for a traditional meal called tlacoyo found in Southern and Central Mexico.

The anthocyanins and polyphenolic flavonoids found in blue maize have antioxidant properties and may be good for human health.

Blue corn is typically made into chips and tortillas as well as used in soups and stews.

5. Blue Milk Mushroom

Other names for the Blue Milk Mushroom include the Indigo Lactarius, Indigo Milk Cap, Indigo Milky, and Indigo Milky. It belongs to the Russulaceae family of plants and is a type of agaric fungus.

You can cook blue milk mushrooms to make a vegetable broth, or you can sautee them and eat them alone or as a garnish to another meal.

Always be sure to purchase mushrooms from a qualified source and never forage for your own mushrooms unless you really know what you are doing!

6. Blue Pansy Flowers

Extra-large blue pansy blossoms have robust, thick stems and are edible. Blue Pansy Flowers are high in antioxidants. The stamen, pistil, and sepals of this flower are all edible. This means that you can just cut the bloom from its stem and start eating.

They make great dessert flowers as well. They can be sprinkled in a bowl of fruit or freshly pressed into cake frosting. However, most chefs opt to candy the blossoms since it prolongs their shelf life and gives them a sweeter, more dessert-like flavor.

7. Blue Potato

The potato known as “Adirondack Blue” has skin that has a faint purple tinge and a blue flesh. Anthocyanins are a specific chemical found in blue potatoes. Free radicals are sucked up by these potent antioxidants, which can lower the risk of cancer, heart disease, and stroke.

You can cook blue potatoes the same way you would cook any potato. You can smash them, mash them, boil them, fry them, etc.

Some of the most popular recipes on my site are for Instant Pot Boiled Potatoes, Instant Pot Potato Salad, and Mexican Potatoes.

8. Blue Pumpkins

Select types of round winter squash are called “Blue Pumpkins” and have naturally blue rinds. The Jarrahdale Pumpkin and the Queensland Blue Pumpkin are two well-liked types of blue pumpkins that are native to Australia.

Pumpkins are very healthy and full of vitamins, minerals, and antioxidants.

Blue Pumpkins can be made the same way you would make a regular pumpkin. It is a terrific option for individuals who prefer a more savory taste in their pie filling because the flavor is not excessively sweet.

10. Filius Blue Pepper

Filius Blue Peppers are a traditional Mexican chili, similar to a poblano pepper. It is a small plant that doesn’t become much taller than 2 feet, and because of its blue-tinged foliage and delicate white blossoms, it makes a lovely container plant as well.

You can use Filius Blue Peppers to make delicious salsas and other peppery sauces. You can also use them fresh in salads and sandwiches.
