Even though vegetables may be the last food group you think of when trying to gain weight, know that there are many surprisingly high-calorie vegetables available on the market that will help you bulk up.
Besides, consuming calorie-dense veggies will also make you have a healthier eating pattern by increasing your daily intake of vitamins and minerals. After all, the American Heart Association recommends 5 daily servings of vegetables for a diet of 2000 calories per day.
To find the vegetables that have the most calories and the greatest impact on your weight gain efforts, we analyzed over 270 common vegetables from USDA’s database.
Here are the top 5 vegetables with the highest number of calories per 100 g (3.5 oz):
Vegetables are generally known for their low-calorie contents, so that is why it's surprising for many people to find out there are many vegetables that can help them gain weight by being pretty high calorie-wise.
Also, because, generally, vegetables contain small amounts of fatty acids, most calorie-dense veggies are high-calorie low-fat foods. So, vegetables are one of your best allies if you're on a low-fat diet.
Typically, the vegetables that make you gain weight are beans, such as pinto beans, starchy vegetables, like yams, and the dried forms of some other veggies, like chile peppers and carrots.
As a bonus, dried vegetables will help you gain weight without filling you because they are low-volume high-calorie foods.
Below you can find a list of 15 high-calorie vegetables ordered by their total calories.
Dried chile peppers are unusually high-calorie compared to other vegetables.
The vegetable with the most calories is the pasilla pepper, a type of dried chile pepper that has 345 calories per 100 g (3.5 oz).
Other examples of high-calorie chile peppers are the sun-dried hot chile peppers, which have 324 calories per 100 g (3.5 oz), and the dried ancho peppers, which are packed with 281 calories per 100 g (3.5 oz).
Pasilla peppers are rich in carbs and have plenty of fats while carrying a decent amount of protein as well.
In terms of micronutrients, they are packed with vitamin B6, iron, and magnesium while featuring some vitamin C and calcium as well.
Most of the calories in dried hot chile peppers come in form of carbs, but these peppers also feature decent amounts of protein and fats. Also, they have a variety of vitamins and minerals.
Even though Ancho peppers contain mainly carbs, they also carry fair amounts of protein and fat.
If you are trying to gain weight, you may want to snack on dehydrated carrots instead of their usual form.
Dehydrated carrots have 8 times more calories than simple carrots, this fact making them a surprisingly high-calorie vegetable that will help you gain weight.
Dehydrated carrots are one of the high-calorie vegetables on this list due to their carb-filled content. Also, dried carrots are chockful of vitamins and minerals.
However, keep in mind that eating too many carrots can trigger carotenemia, a condition that manifests through orange-tinted skin caused by the high amount of beta-carotene absorbed by your body.
Chives are similar to green onions, but, when dried, they transform into a high-calorie vegetable that will definitely help you gain weight. After all, dried chives have over 300 calories per 100 g (3.5 oz).
Although most of the calories in dried chives come from their high-carb content, they are also a good source of protein.
Moreover, 100 g (3.5 oz) of dried chives will overload you with vitamin A, vitamin C, and iron while almost satisfying your daily calcium needs.
Some of the dried varieties of Asian mushrooms, such as shiitake mushrooms or cloud ears fungi, are surprisingly high-calorie vegetables, both containing almost 300 calories per 100 g (3.5 oz).
Dried shiitake mushrooms are rich in carbs and have decent amounts of protein as well.
However, in terms of micronutrients, shiitake mushrooms don’t carry as many vitamins and minerals as other high-calorie vegetables on this list.
As it’s the case with shiitake mushrooms, dried cloud ears fungi are loaded with carbs while carrying fair amounts of protein as well. Micronutrient-wise, dried cloud ears are rich in plenty of minerals and vitamins.

Dried spirulina is a dehydrated seaweed that makes for a high-calorie vegetable due to its rich nutritional content.
Besides helping you gain weight, spirulina has other health benefits as well.
"Spirulina is also good to lower risk of heart disease and helps to manage blood sugar levels. It’s a great source of protein and good for bone health and high in antioxidants as well," says certified nutrition coach Adylia-Rhenee Gutierrez.
Most of the calories in dried spirulina come from its proteins, but it also carries plenty of carbs and a few grams of fats as well.
Besides, dried spirulina is a treasure of iron while offering good amounts of potassium, and some calcium too.
Dried parsley is a high-calorie vegetable with almost 300 calories per 100 g (3.5 oz) that is mostly used as a condiment.
Most of the calories in dried parsley are owed to its high protein and carb content. In addition, dried parsley is a treasure of vitamin C, iron, and calcium while sporting a decent amount of vitamin A.
While simple tomatoes are considered a low-calorie vegetable, sun-dried tomatoes are high-calorie vegetables that have 14 times more calories.
To sun-dry tomatoes, all you need to do is to cut tomatoes in half and leave them under the sun with a pinch of salt on them.
Sun-dried tomatoes are rich in carbs but also offer a fair quantity of protein.
Although they have under 200 calories, chickpeas, also known as garbanzo beans, can still be considered a high-calorie vegetable since they have much more calories than other vegetables that don’t even reach the 50-calorie mark.
The main reason why boiled chickpeas have an increased number of calories is the good number of carbs and protein found in them, which also makes them a great food to add to pre-workout meals for muscle gain.
Mineral-wise, boiled chickpeas offer iron and calcium.
Also known as manioc or yuca, cassava is a starchy high-calorie vegetable with South-American origins that can help you gain weight.
Having almost no fat and proteins, most of Cassava's calories come from the carbs in its composition. However, cassava has a good amount of vitamin C and carries small quantities of vitamin B6 and magnesium.
Being a popular high-calorie vegetable that contains almost 150 calories per 100 g (3.5 oz), garlic has been linked to multiple potential therapeutic effects, such as fighting cardiovascular diseases, tumors, and microbes.
Most of garlic’s calories are owed to the solid quantity of carbs in it. In addition, garlic has some proteins and is rich in vitamin C.
Boiled beans are high-calorie vegetables that will help you gain weight with their solid carb content and fair quantity of proteins.
After all, beans are one of the most effective weight gain foods for women. About 2 in 10 females who successfully manage to gain weight eat beans regularly.
Also, boiled beans and lentils are good sources of fiber.
"The beans, lentils are a great source of fiber that’s so important for everyone’s diet," says certified nutrition coach Adylia-Rhenee Gutierrez.
Here are the different types of boiled high-calorie beans and their calories per 100 g (3.5 oz):
How to eat? Boiled beans are generally eaten as a side dish or as a primary ingredient in a soup or stew. However, that doesn’t stop you to fill a bowl and snacking on this calorie-dense vegetable. Also, you will find that beans go well in classic Mexican dishes, such as burritos or chili.
Pinto beans are also a budget-friendly vegetable since they are the most affordable veggie on our list of cheap high-calorie foods for weight gain.

Popular in Asian cuisine, soybean sprouts are one of the vegetables with the highest calories, so they can help you gain weight.
Moreover, since they have fewer carbohydrates than other veggies but still have plenty of calories, soybean sprouts are the only vegetables on the list of high-calorie low-carb foods.
Soybean sprouts carry proteins, carbs, and fats along with a wide range of minerals and vitamins.
Boiled yams are starchy high-calorie vegetables that make for a more caloric alternative to the classic potatoes.
Boiled yams are mainly carbs and have increased levels of vitamin C.
Lentils are lens-shaped high-calorie vegetables that need to be cooked to be safely consumed. Other than that, they are very energizing since they are packed with carbs and proteins.
The increased level of calories in boiled lentils is given by their carb and protein content. Also, lentils are a small treasure of iron.
