How many calories in a half a cup of garlic mashed potatoes?

Quick Answer

A half cup of garlic mashed potatoes contains approximately 115 calories. This is based on garlic mashed potatoes containing 230 calories per cup on average. So dividing 230 calories per cup in half gives us 115 calories per half cup. The exact calorie count can vary depending on factors like the potato type, cooking method, and amount of fat and garlic used. But in general, 115 calories per half cup is a reasonable estimate for garlic mashed potatoes.

Calories in Potatoes

Potatoes are relatively high in calories and carbohydrates compared to other vegetables. Here are some key facts about the calories in different types of potatoes:

  • Russet potatoes: 111 calories per 100g
  • Red potatoes: 89 calories per 100g
  • Sweet potatoes: 86 calories per 100g
  • White potatoes: 77 calories per 100g

As you can see, russet potatoes tend to be higher in calories than red, sweet, or white potatoes. Russets have a drier, fluffier texture that lends itself well to mashing.

The exact calories can vary depending on factors like:

  • Potato variety – Some types are more dense and higher in calories than others
  • Cooking method – Frying adds more fat and calories vs. baking or boiling
  • Preparation – Mashed, fried, baked etc. affects calories
  • Additions – Butter, milk, oil increases calories

But per 100g (about 3.5 ounces), most potatoes range from 70-120 calories depending on the type.

Calories in Mashed Potatoes

When potatoes are boiled and mashed with milk, butter, and seasonings, the calorie count increases. Here are some estimates for calories in mashed potatoes:

  • 1 cup plain mashed potatoes: 220 calories
  • 1 cup milk mashed potatoes: 235 calories
  • 1 cup buttermilk mashed potatoes: 242 calories
  • 1 cup garlic mashed potatoes: 230 calories

Extra ingredients like butter, cream, cream cheese, sour cream, cheese, and bacon can further increase the calories in mashed potatoes. Typical all-in mashed potato recipes end up in the range of 230-320 calories per cup.

So for a half cup serving, you would expect roughly:

  • Plain mashed potatoes: 110 calories
  • Milk mashed potatoes: 117 calories
  • Buttermilk mashed potatoes: 121 calories
  • Garlic mashed potatoes: 115 calories

Again, the exact amount depends on the ingredients used. But a plain half cup of mashed potatoes is around 100-120 calories, while richer preparations would be closer to 140-160 calories.

Calories in Garlic

Garlic adds a negligible amount of calories to mashed potatoes.

Here is the calorie breakdown for garlic:

  • 1 clove of garlic: 4 calories
  • 1 teaspoon minced garlic: 4 calories
  • 1 tablespoon minced garlic: 12 calories

Unless you are adding several tablespoons of garlic to your mashed potatoes, the extra calories from garlic will be minimal. It adds more flavor than calories.

Calories from Fat and Butter

The main additions that increase the calories in mashed potatoes are fat-based ingredients like butter, cream, and oil.

For example:

  • 1 tablespoon butter: 100 calories
  • 1/4 cup heavy cream: 115 calories
  • 1/4 cup olive oil: 240 calories

Just adding a couple tablespoons of butter can add 200+ extra calories to a serving of mashed potatoes.

Replacing some of the butter with lower calorie milk and seasonings is a good way to lighten up mashed potatoes. You can also use lower fat milk or Greek yogurt instead of heavy cream.

Low Calorie Ways to Prepare Mashed Potatoes

Here are some tips for lightening up mashed potatoes:

  • Use lower calorie potatoes like red or white potatoes instead of Russets
  • Replace half the butter with low-fat milk
  • Use Greek yogurt instead of sour cream
  • Season with garlic, herbs, salt, pepper instead of butter
  • Skip adding cheese, bacon, or other high-fat toppings
  • Use a potato masher instead of a food processor for a less smooth texture
  • Substitute cauliflower for up to half the potatoes to reduce calories

Following these tips can help keep the calorie count for a 1/2 cup serving of mashed potatoes to around 100 calories or less.

High Calorie Ways to Prepare Mashed Potatoes

On the other hand, you can easily double or triple the calories in mashed potatoes by adding high-fat, high-calorie ingredients:

  • Use butter and whole milk or heavy cream as the base
  • Mix in sour cream, cream cheese, or ricotta cheese
  • Top with gravy, cheese, crumbled bacon
  • Add in mix-ins like caramelized onions, roasted garlic, or sautéed mushrooms in butter or oil
  • Drizzle with melted butter, olive oil, or truffle oil
  • Garnish with fried shallots or onions

A rich preparation like this could have well over 300 calories in just a half cup serving. That’s fine for special occasion comfort food, but not as an everyday side dish if you are watching your calorie intake.
