Is Swiss fondue lactose free?

Quick Answer

Traditional Swiss fondue is not lactose free. It is made with cheese, which contains lactose. However, there are lactose-free options available using alternate cheese recipes or lactose-free dairy products.

What is Swiss fondue?

Swiss fondue is a famous dish from Switzerland consisting of melted cheese served communally with bread for dipping. The traditional Swiss fondue recipe calls for mixing together Emmentaler and Gruyère cheeses with white wine and other ingredients. This mixture is heated in a communal pot called a “caquelon” until the cheese melts into a smooth, creamy sauce. Pieces of bread are then speared with long forks and dipped into the warm cheese sauce.

Traditional Swiss fondue ingredients

– Emmentaler cheese: The most commonly used cheese for fondue, made from cow’s milk.

– Gruyère cheese: Adds strong, earthy flavor to the fondue. Also made from cow’s milk.

– White wine: Usually a dry Swiss white wine like Fendant or Chasselas. The acidic wine helps the cheeses melt smoothly.

– Garlic: Adds extra flavor. Usually just a clove or two, rubbed on the inside of the caquelon.

– Kirsch: A clear cherry brandy that enhances the flavor. Just a splash.

– Nutmeg: A dusting of freshly grated nutmeg.

– Cornstarch or flour: Helps bind the melted cheese into a creamy emulsion.

– Pepper

The cheese makes it not lactose free

The problem with traditional Swiss fondue is that both Emmentaler and Gruyère are made from cow’s milk. Cow’s milk naturally contains lactose, a milk sugar.

During cheesemaking, most of the whey is drained off, but some residual lactose remains trapped in the cheese curds. Therefore, cheeses like Emmentaler and Gruyère are not lactose-free.

When these cheeses melt into fondue, the lactose becomes dissolved throughout the cheese sauce. This means any traditional Swiss fondue made with cow’s milk cheese will contain lactose.

Lactose intolerance and dairy allergies

Lactose intolerance and dairy allergies are two medical conditions that require avoidance of lactose or dairy products.

Lactose intolerance

Lactose intolerance is the inability to fully digest lactose due to a deficiency of the enzyme lactase. Lactase breaks down lactose into simple sugars for absorption.

With lactose intolerance, undigested lactose passes through the intestines, causing gas, bloating, cramping and diarrhea. Even small amounts of lactose can trigger symptoms in lactose intolerant individuals.

It’s estimated that 65% of the global population has some degree of lactose intolerance. Rates are higher in some ethnic groups, such as African Americans, Hispanics, Asians, and Native Americans.

Dairy allergy

A dairy allergy is caused by the immune system inappropriately reacting to milk proteins, like casein. With a dairy allergy, even small traces of milk can trigger an immune response with symptoms like:

– Hives, itching, eczema
– Runny nose, sneezing, asthma
– Vomiting, diarrhea
– Anaphylaxis in severe cases

Dairy allergies affect around 2-3% of infants but are usually outgrown by age 3. They persist in less than 1% of adults.

Lactose-free Swiss fondue options

To allow those with lactose intolerance or dairy allergies to enjoy Swiss fondue, there are some lactose-free options:

Lactose-free milk and cheese

Lactose-free dairy products are treated with the lactase enzyme to pre-digest the lactose. These include:

– Lactose-free milk: Can be substituted measure-for-measure for regular milk in recipes.

– Lactose-free cheeses: Specialty lactose-free versions of cheeses like cheddar, mozzarella and Swiss. Work well melted.

– Aged cheeses: Hard cheeses like Parmesan and cheddar naturally lose most of their lactose during aging. Can help reduce the lactose content of fondue.

Non-dairy milks and cheeses

Plant-based milks and cheeses avoid dairy and lactose altogether. Options include:

– Almond milk: Substitute 1:1 for cow’s milk.

– Cashew cheese: Can mimic soft melted cheese when blended with tapioca and agar flakes.

– Nutritional yeast: Adds nutty, cheesy flavor to fondue when blended with plant milk and seasonings.

Tips for lactose-free fondue

– Use a 50/50 blend of lactose-free Swiss cheese and aged Swiss cheese for flavor.

– Mix in small amount of plant-based cheese like cashew cheese.

– Use lactose-free milk instead of regular milk if recipe calls for it.

– Add extra garlic, kirsch and spices to boost flavor if omitting dairy.

– Prepare cornstarch slurry with non-dairy milk or water instead of regular milk.


Here is a nutrition comparison between traditional Swiss fondue and lactose-free versions.

Nutrition Facts Per 1/2 Cup Serving Traditional (with dairy) Lactose-Free Non-Dairy
Calories 330 330 150
Fat 27g 27g 9g
Carbs 1g 1g 6g
Protein 16g 16g 4g
Calcium 327mg 327mg 100mg

Key points:

– Lactose-free versions with lactose-free dairy have similar nutrition to regular dairy fondue. Still high in fat and calories.

– Non-dairy fondue is significantly lower in fat, calories and protein. Also less calcium since no dairy.

– Any fondue should be eaten in moderation as part of a healthy diet. Dip veggies instead of just bread for more nutrition.

Cost Comparison

Here’s how the costs of traditional vs. lactose-free Swiss fondue typically compare:

Version Cost
Traditional $15-$20 for ingredients
Lactose-free dairy $20-$25
Non-dairy $15-$25

Key points:

– Lactose-free dairy products tend to cost 20-30% more than regular dairy.

– Non-dairy options can cost about the same or slightly more depending on ingredients used.

– Making your own fondue at home is cheaper than dining out. Restaurants mark up fondue prices significantly.

Taste Comparison

How does lactose-free Swiss fondue compare taste-wise?

Version Taste
Traditional Rich, decadent, complex flavor
Lactose-free dairy Very similar taste and texture
Non-dairy Comparable but simpler, less nuanced flavor

Key points:

– Lactose-free dairy fondue is nearly identical in taste and texture to traditional.

– Non-dairy fondue can mimic cheese flavor but is less complex.

– Spice blends, wine, kirsch all still add lots of flavor.

– Overall deliciousness comes down to recipe and cooking method, not just ingredients.

Making It At Home vs. Eating Out

If you need to eat lactose-free, making Swiss fondue at home has some advantages compared to ordering it in a restaurant:

Homemade Restaurant
Control ingredients Yes No
Ensure lactose-free Yes Risk of cross-contact
Cost Lower Higher
Portion size Adjustable Fixed

Key points:

– Making your own allows you to control the ingredients and ensure it’s lactose-free.

– Restaurants can’t guarantee no cross-contact with lactose.

– Homemade costs a fraction of dining out.

– At home you can adjust recipe and portion size to your needs.

Cooking Tips

Here are some handy cooking tips for making lactose-free Swiss fondue successfully at home:

– Use a real fondue pot or caquelon if you have one. The thick enamel holds and distributes heat evenly.

– If you don’t have a fondue pot, use a heavy stainless steel pot. Avoid nonstick types.

– Stir frequently to prevent burning and help incorporate starch slurry.

– Add liquids slowly and check consistency before adding more to avoid being too thin.

– Keep flame or heating element on very low to keep fondue smooth and creamy, not clumpy or separated.

– Provide lactose-free dipping options like sourdough bread, apples, pears, broccoli, potatoes.

– Plan for about 6 oz fondue per person if serving as main dish, or 2-4 oz as an appetizer.


While traditional Swiss fondue contains lactose, with some ingredient tweaks and substitutions it can be made lactose-free and just as delicious. Opt for lactose-free dairy products or venture into non-dairy cheeses. Make it at home to control ingredients and avoid cross-contact. With the right recipes and techniques, you can enjoy all the ooey, gooey cheesy goodness of fondue even with dairy restrictions. Just be sure to keep your fork for dipping if you want to uphold fondue tradition!
