The most complete list of blue colour vegetables, EVER. Including pictures, fun facts, and uses in cooking. From root veggies to mushrooms, seeds, and edible flowers! 💙

Intro and Disclaimer

Seventeen blue vegetables including names, photos, fun facts, and uses in cooking. I guarantee that this is the most comprehensive list you can find on the Internet!

A quick disclaimer is that some of them may not look like real blue, but they do have the word “blue” in their names, whereas others are naturally blue in color. Moreover, I am using the broad definition of vegetables as any edible parts of plants, including seeds and flowers!

Alright, let’s jump right in! 💙

3 Blue Root Vegetables

1. Blue Carrot

A bunch of rainbow colored carrots, arranged to make a circular shape.

Fun fact(s): Blue / purple carrots were the real original color of carrots! What a surprise, given that orange carrots are what we’re used to (which btw, appears in my orange vegetables list)!

Uses: You can eat blue carrots raw in salads and bowls (like in this healthy poke bowl), roasted, or simply paired with dips like this no-garlic hummus or cream cheese dip!

2. Blue Pumpkin

A bunch of blue pumpkins with one big blue pumpkin in the center.

Fun fact(s): Two of the most popular blue pumpkin varieties are the Jarrahdale pumpkin and Queensland blue pumpkin, both grown in Australia.

Uses: Use them the same way you would use regular pumpkins! So think of soups, baked goods, or roasting.

3. Blue Potato

Vitelotte potatoes, some whole and some cut open to show the purplish flesh and the black skin.

Fun fact(s): There are many different kinda of blue potatoes! Starting from Adirondack blue potatoes, salad blue potatoes, and all blue potatoes. They all have a purplish color, similar to the Vitelotte potatoes in the image above.

Uses: Roast, mash, or bake them like regular potatoes for a colorful twist. They also make vibrant potato salads or fries (like in my adobo potato fries)!

6 ‘Common’ Blue Vegetables

1. Blue Corn

An ear of dark blue corn in the middle, with a bunch of other red, black, yellow and white corn around.

Fun fact(s): Blue corn has been grown for centuries by Native Americans, and is now cultivated in some parts of the United States too. Plus, there are other colors of corn too such as red, purple, and pink corn which appear in my red veggies, purple veggies, and pink veggies posts respectively!

And speaking of health benefits, blue corn has been shown to lower risk of some cancers and also helps in lowering blood pressure! (source: Journal of Medicinal Food)

Uses: The most common use is to turn them into blue corn tortillas, cornbread, and in other Mexican recipes!

2. Blue Tomatoes

Fun fact(s): There are so many varieties of blue tomatoes, such as blue bayou (picture above), fahrenheit blue, and indigo ruby tomatoes. Moreover, the blue color comes from anthocyanins which may help with inflammation, protect against diabetes and certain types of cancer, lower heart disease risk, and improve brain health! (source: Healthline)

And if you’re wondering how anthocyanins work, they suck up free radicals, which then results in many of the health benefits above!

Uses: Use them in salads or as a colorful garnish. I highly recommend serving them raw to preserve their beautiful color, such as subbing the red tomatoes in this tomato carpaccio salad or these vegetarian tea sandwiches.

3. Filius Blue Pepper

A bunch of filius blue pepper being arranged in a vertical line, with red small peppers and orange peppers around.

Fun fact(s): Filius blue peppers have a similar spiciness level as cayenne pepper, which is between 30,000 to 50,000 Scoville heat units!

Uses: Use them fresh in salsas, sauces, sandwiches, stir-fries, or pickled for a spicy kick.

4. Blue Cabbage

Fun fact(s): A true blue cabbage is actually really rare and since they aren’t widely cultivated. However, you can turn a red cabbage into blue when you sauté it, as explained in this The Daily Meal article!

Also note that some people just call your red/purple cabbage “blue cabbage”, but there is definitely more than one variety!

Uses: Use them the same way you would use red/white cabbage, so shredded for slaws and sauerkraut, raw in salads or bowls, or in these noodle spring rolls!

5. Blue Kale

Fun fact(s): Some of the most common blue kale varieties include the dazzling blue kale and vates blue curled scotch kale. Both of them have prominently green leaves, with dazzling blue kale having some purplish leaves!

Uses: Use them in any way you would use the regular green kale, such as in salads, soups, roasted, air-fried, or even sneaked into smoothies!

6. Tall Blue Lettuce

Fun fact(s): Nativa Americans use the extract of tall blue lettuce to treat pain, diarrhea, and vomiting! (source: Go Botany)

Moreover, they often grow in the wild, which is why I don’t have a picture that I can display here. But a quick Google search would help if you’re curious!

Uses: They are quite bitter so you can either eat them raw or cook them, especially if you’ve got firm and rigid stalks! If you would like to learn more about this plant, check out this article by Forager Chef.

2 Blue Mushrooms

2. Blue Oyster Mushroom

Fun fact(s): Blue oyster mushrooms start with a vibrant blue cap, which fades to light blue to gray as they mature.

Uses: Use them the same way you would use regular oyster mushrooms, like replacing the shiitake with some blue oyster mushroom in this mushroom sushi!
