Swiss French dressing is a tangy, red French-style salad dressing made with oil, vinegar, ketchup, and finely grated Swiss cheese. This version blends into a savory, lightly creamy dressing that clings well to lettuce and makes a handy dip or sandwich spread, too. The name is used for different variations; this recipe is a practical Swiss-cheese take rather than a claim to one traditional formula.
Ingredients
- 1/2 cup (120 ml) neutral oil, such as canola, sunflower, or light olive oil
- 1/4 cup (60 ml) apple cider vinegar
- 1/3 cup (80 ml) ketchup
- 1 tablespoon (12 g) granulated sugar
- 1 tablespoon (10 g) finely grated yellow onion
- 1 teaspoon (5 g) Dijon mustard
- 1 teaspoon (5 ml) Worcestershire sauce
- 1/2 teaspoon (1 g) sweet paprika
- 1/4 teaspoon (about 1 g) garlic powder
- 1/2 teaspoon (3 g) fine salt
- 1/8 teaspoon (about 0.3 g) freshly ground black pepper
- 1/3 cup (35 g) finely grated Swiss cheese
- 1 tablespoon (15 ml) water, plus up to 1 tablespoon (15 ml) more if needed
Instructions
- Prepare the ingredients. Finely grate the onion and Swiss cheese; a fine grater helps both blend smoothly. Measure the vinegar, ketchup, seasonings, and oil. If the cheese is in slices, cut it into small pieces first, though a block of cheese is easier to grate evenly.
- Blend the flavor base. Add the vinegar, ketchup, sugar, onion, Dijon, Worcestershire sauce, paprika, garlic powder, salt, pepper, and 1 tablespoon of water to a blender or a tall cup suitable for an immersion blender. Blend for about 20 seconds, until the onion is finely dispersed and the mixture looks even. Scrape down the sides if a little seasoning sticks above the liquid.
- Stream in the oil. With the blender running on low, pour in the oil in a thin, steady stream. Take about 30 to 45 seconds to add it rather than tipping it in all at once. Blending gradually disperses the oil into small droplets, giving the dressing a more cohesive texture. Stop once it looks glossy and slightly thickened.
- Add the cheese. Add the grated Swiss and pulse several times, just until it is distributed. Avoid running the blender for a long time after adding the cheese; prolonged blending can warm the dressing and make its texture less pleasant. Taste a small spoonful, then adjust salt, pepper, sugar, or vinegar in small amounts.
- Adjust and serve. If you want a thinner dressing, blend in the remaining tablespoon of water a little at a time. Transfer the dressing to a clean jar or covered container. It can be served right away; if it has been chilled, shake or stir it before dressing the salad.
Tips
- Grate the cheese finely. Fine shreds blend into the dressing more readily than thick shreds and are less likely to leave chewy clumps. Swiss cheese, often sold as a mild, holey cheese in US supermarkets, works well here. Emmentaler is a useful alternative if you want a more pronounced nutty flavor; it may make the finished dressing taste a little sharper.
- Choose a mild oil. Canola or sunflower oil keeps the vinegar, tomato, and cheese flavors in balance. Extra-virgin olive oil is usable, but its peppery taste can dominate the mild Swiss cheese, and olive oil may turn cloudy or firm in the refrigerator. If you use it, let the dressing sit at room temperature briefly and shake well before serving.
- Balance the seasoning after blending. Ketchup, Worcestershire sauce, and cheese all bring their own salt and sweetness, so taste before adding more. If the dressing seems too sweet, add vinegar 1 teaspoon (5 ml) at a time. If it tastes too sharp, add a pinch of sugar or a small splash of water instead of pouring in more oil.
- Fix separation without overworking it. A little separation is normal in a homemade dressing, particularly after chilling. Shake the closed jar firmly or whisk the dressing in a bowl. If it remains thin or looks broken, blend in a teaspoon of Dijon mustard or a teaspoon of water to help it come together again.
Serving Suggestions
Use about 2 tablespoons (30 ml) per serving as a starting point, then add more only as needed. This quantity makes roughly 1 1/2 cups (355 ml), enough for about 12 modest salad portions. Toss it with crisp iceberg or romaine, shredded carrots, cucumber, and tomato for a straightforward side salad. Its tangy, savory flavor also suits chopped salads with lettuce, celery, radish, and extra Swiss cheese; add the dressing shortly before serving so the greens stay crisp.
For a more filling lunch salad, spoon the dressing over sliced turkey, hard-boiled egg, or chickpeas along with crunchy vegetables. Keep any cooked or prepared toppings properly chilled until serving. The dressing is also useful beyond leafy salads: spread a thin layer inside a turkey or vegetable sandwich, drizzle it over a cold pasta salad, or serve it as a dip for raw bell pepper, celery, and cucumber sticks. Start with a small amount on sandwiches because its vinegar and ketchup flavors are concentrated. If using it on warm vegetables, let them cool until just warm rather than hot; the cheese can soften and the dressing may become oily when heated.
Variations
Make it without cheese: Leave out the Swiss and add 1 tablespoon (15 ml) of water to keep the dressing pourable. The result is brighter and more like a classic red French-style vinaigrette, with less of the mild, nutty flavor that defines this version. For a slightly creamier texture without dairy, blend in 1 teaspoon (5 g) of extra Dijon mustard.
Make it more savory: Replace the Swiss with finely grated sharp cheddar or a small amount of Parmesan. Cheddar gives the dressing a more pronounced, tangy cheese note; Parmesan tastes saltier and more assertive, so begin with 1/4 cup (25 g) and taste before adding more salt. For a vegetarian version, check that the Worcestershire sauce is labeled vegetarian, or substitute 1 teaspoon (5 ml) soy sauce. Soy sauce adds a deeper, saltier taste, so reduce the added salt at first.
Adjust the sweetness and spice: For a less sweet dressing, start with 2 teaspoons (8 g) sugar, then add more only after tasting. For a warmer flavor, increase the paprika to 3/4 teaspoon (about 1.5 g), or use smoked paprika for a gentle smoky note. A pinch of cayenne adds heat without changing the dressing’s basic character. Add spicy ingredients sparingly and blend again before deciding whether you want more.
Make it thicker for dipping: Use only 1 tablespoon (15 ml) water, then blend in an extra tablespoon of finely grated Swiss. The dressing will be richer and less pourable, so it works better as a vegetable dip or sandwich spread than as a light salad coating. For a thinner dressing, add cold water a teaspoon at a time until it reaches the consistency you want.
Storage and Reheating
Transfer the dressing to a clean, airtight container and refrigerate it promptly. Because this recipe contains fresh grated cheese and onion, do not leave it at room temperature for more than 2 hours; refrigerate it sooner if the room is particularly warm. Keep it chilled and use it within 3 to 4 days. The cheese may settle or the oil may separate during storage, so shake the container well or stir before each use. If the dressing has an unusual smell, visible mold, or an unexpected change in texture, discard it rather than tasting it.
This is a cold dressing and does not need reheating. Warming it can separate the oil and soften the cheese into an uneven texture. If it becomes firm or cloudy in the refrigerator, let the amount you plan to use stand at room temperature for 10 to 15 minutes, then shake it. Do not leave the whole jar out for an extended period; return it to the refrigerator after serving. For best quality, make only the amount you expect to use within a few days rather than trying to store it long term.
Frequently Asked Questions
Is Swiss French dressing the same as regular French dressing?
Not necessarily. French dressing commonly refers to a red, tangy dressing made with oil, vinegar, and a tomato ingredient such as ketchup. Recipes vary in sweetness and seasoning. This version adds grated Swiss cheese, giving it a more savory flavor and a slightly fuller texture. If you prefer a simpler dressing, omit the cheese and add a little water as described in the variations.
Can I make the dressing without a blender?
Yes. Finely grate the onion and cheese, then whisk the vinegar, ketchup, sugar, seasonings, and mustard together in a bowl. Whisk continuously while adding the oil in a very slow stream. Stir in the cheese at the end. The result may be less smooth than a blended dressing, but careful whisking still makes a good pourable version. A jar with a tight lid also works: shake the base ingredients and oil vigorously, then stir in the cheese.
What kind of Swiss cheese should I use?
A mild Swiss-style cheese from the supermarket is convenient and gives the dressing a gentle, nutty taste. If you can find Emmentaler, it is a good alternative with a more distinct flavor. Use a block and grate it finely when possible; pre-shredded cheese may contain anti-caking ingredients that can make the dressing slightly grainy. Avoid using a very strong cheese unless you want its flavor to take the lead.
Can I make Swiss French dressing ahead of time?
Yes. Make it up to 3 or 4 days ahead, store it covered in the refrigerator, and shake or stir it before serving. The onion and cheese flavor may become a little more noticeable as it sits, so taste it again before pouring it over a salad. If it has thickened, loosen it with a teaspoon of cold water at a time. Keep it refrigerated and follow the 2-hour room-temperature limit when serving.
Why did my dressing separate or turn thick?
Oil and vinegar naturally separate, and chilling can make the oil look cloudy or the cheese settle. These changes do not always mean anything is wrong. Shake the jar or whisk the dressing to recombine it; if needed, blend in a teaspoon of water or Dijon mustard. If it is too thick, add cold water gradually. If it is newly made and very oily, the oil may have gone in too quickly, so blend again while adding a teaspoon of water slowly.
