How many calories in a baked stuffed mushroom?

Quick Answer

A medium baked stuffed mushroom contains around 15-20 calories. The exact calorie count depends on the size of the mushroom and what it is stuffed with. Stuffings with cheese, meat or oil will be higher in calories than veggie-based fillings. On average, a 3-4 inch wide stuffed mushroom has 15-20 calories.

Calories in Different Types of Stuffed Mushrooms

The calories in a baked stuffed mushroom can vary greatly depending on the ingredients used in the stuffing. Here are some estimates for common stuffed mushroom recipes:

Cheese Stuffed Mushrooms

Cheese stuffed mushrooms are one of the most popular options. One medium mushroom stuffed with cheese has around 20-30 calories. Stuffings with higher fat cheeses like cheddar or Monterey Jack will be higher in calories than low fat cheeses like mozzarella or feta.

Sausage Stuffed Mushrooms

Sausage stuffed mushrooms have more calories due to the high fat content of sausage meat. Each mushroom stuffed with a meat-based sausage filling will have around 30-40 calories.

Seafood Stuffed Mushrooms

Seafood like shrimp or crab adds calories to stuffed mushrooms. Expect around 25-35 calories per mushroom stuffed with a seafood filling.

Veggie Stuffed Mushrooms

Mushrooms stuffed with lower calorie veggies like spinach, tomatoes and onions will be lower in calories. Each veggie stuffed mushroom has around 15-20 calories.

Vegan Stuffed Mushrooms

Vegan stuffed mushroom recipes replace meat and cheese with plant-based ingredients like nuts, lentils and chopped veggies. A vegan stuffed mushroom may have around 20-25 calories each.

Stuffed Mushroom Serving Sizes

As you can see, the calorie counts provided above are just estimates per mushroom. The specific calorie count will depend on the size of the mushroom cap and how much stuffing is used.

Here are some typical serving sizes for stuffed mushrooms and the calories in each:

Serving Size Calories*
2 small stuffed mushrooms (2-3 inches wide) 30-40
3 medium stuffed mushrooms (3-4 inches wide) 45-60
4 large stuffed mushrooms (4-5 inches wide) 60-80

*Using a cheese stuffing as a benchmark

As you can see, those enjoying stuffed mushrooms as an appetizer should plan for 30-50 calories per 3 mushrooms depending on the size and stuffing.

Factors That Increase Calories in Stuffed Mushrooms

Certain preparation methods and ingredients can add calories to stuffed mushrooms:

High Fat Stuffing Ingredients

The highest calorie stuffings include fatty meats like sausage or bacon, full fat cheeses and creams or oils. Opting for low-fat ingredients like chopped veggies will reduce the calories.

Large Mushroom Caps

The bigger the mushroom cap, the more space there is for stuffing. More stuffing equals more calories. Select smaller to medium mushroom caps to control calories.

Breading or Batter

Some recipes call for coating or battering stuffed mushrooms before baking. Breading or battering adds extra calories from carbohydrates and oil. For lower calories, avoid this extra coating.

Deep Frying

While baking is standard, you can also find recipes for deep fried stuffed mushrooms. Deep frying can almost double the calories compared to baking.

Tips for Lightening Up Stuffed Mushrooms

Here are some easy ways to reduce the calories in stuffed mushroom recipes:

– Use small or medium mushroom caps instead of large caps.

– Choose low-fat cheeses like feta or goat cheese for the stuffing.

– For a meaty flavor, use chopped mushrooms stems instead of sausage or bacon.

– Load up on nutrient-packed chopped veggies like spinach, bell peppers, onions and tomatoes.

– Skip breading or battering the mushrooms before cooking.

– Opt for healthy cooking methods like roasting, baking or air frying instead of frying.

– Go easy on oils or butter – a light spritz or brushing is likely enough.

– Serve stuffed mushrooms as a side dish instead of an appetizer so the portion is smaller.

Nutrition Benefits of Stuffed Mushrooms

While they aren’t the lowest calorie appetizer option, stuffed mushrooms do provide important nutrients, including:


Raw mushrooms contain antioxidants like ergothioneine and selenium. These compounds help reduce inflammation and oxidative stress. Many antioxidants are maintained after cooking.

B Vitamins

Mushrooms provide B vitamins like riboflavin, folate, thiamine, niacin, and biotin. B vitamins help convert food into energy and play a role in nervous system function.


Mushrooms are high in potassium, an essential mineral for fluid balance, nerve signaling and heart health. A 3.5 ounce serving of mushrooms contains around 16% of the recommended daily potassium.

Vitamin D

Exposure to UV light boosts levels of vitamin D in mushrooms. Vitamin D promotes strong bones by helping the body absorb calcium.

Immune Support

Research suggests compounds like polysaccharides and beta glucans in mushrooms can support immune function by boosting cell-mediated immunity.


Mushrooms are one of the best non-animal sources of choline, an essential nutrient for liver function, brain health, nerve function and metabolism.

Lean Protein

Protein makes up about 3 grams of every 100 grams of raw mushrooms. Though not a complete protein, this provides healthy support for muscle tissue.


There are around 2 grams of dietary fiber in a cup of mushrooms. The fiber aids digestion and gut health.

So in addition to being low in calories, stuffed mushrooms provide an array of important vitamins, minerals and antioxidants. Keep this nutrient density in mind when preparing stuffed mushrooms for a healthy appetizer.
