What Is Frisco Sauce? (Quick Answer)
Frisco sauce is a creamy, tangy condiment created by the American restaurant chain Steak n Shake. It is best known as the signature topping on the Frisco Melt, a double steakburger served with Swiss and American cheese on grilled sourdough bread.
The base is usually a blend of thousand island dressing and french dressing, sometimes mixed with ketchup, Worcestershire sauce, or pickle relish for extra depth. The exact restaurant recipe is not published, but most copycat versions land very close to the original.

Home made Frisco Sauce Recipe (Copycat Version)
This homemade recipe takes less than five minutes and needs no cooking.
Ingredients
- 120 millilitres thousand island dressing
- 60 millilitres french dressing
- 2 tablespoons ketchup
- 1 teaspoon Worcestershire sauce
- Optional: 1 teaspoon sweet pickle relish
Method
- Add all the ingredients to a small mixing bowl.
- Whisk them together until the colour turns a smooth, pale orange.
- Cover the bowl and chill it in the fridge for at least thirty minutes so the flavours settle.
- Give it a final stir before serving on burgers, sandwiches, or as a dip.
This sauce pairs beautifully with a homemade patty melt, and it also works well as a dip for chips or onion rings, much like the sauces served alongside a good sourdough bread starter at a steakhouse.
What Does Frisco Sauce Taste Like?
The flavour is creamy first, then tangy, with a gentle sweetness that lingers at the end. It is smoother and less sharp than plain ketchup or mustard, which is why it works so well on a rich, cheesy burger.
Fans often compare it to other famous secret sauces, such as Big Mac sauce, though Frisco sauce leans a little sweeter and pinker in colour. If you enjoy a good steak sauce or dipping sauce with your meal, this one sits comfortably in that same family.
Frisco Sauce Ingredients
Most copycat recipes use a short, simple ingredient list. Here is the version that consistently gets the closest match:
- Thousand island dressing, half a cup
- French dressing, a quarter cup
- Tomato ketchup, two tablespoons
- Worcestershire sauce, a small splash
- Optional: mayonnaise, sweet pickle relish, or a pinch of paprika for colour
Some versions also add a touch of mustard or hot sauce for a spicier kick. Feel free to adjust the ratio until the flavour matches what you remember from the restaurant.

Storage Tips
Keep homemade Frisco sauce in a sealed container in the fridge. It stays fresh for up to one week, though some thicker versions with vinegar can last up to three weeks. Always give it a quick stir before each use, since the ingredients can separate slightly over time.
Frequently Asked Questions
Is Frisco sauce the same as thousand island dressing?
No, though they are closely related. Frisco sauce usually combines thousand island dressing with french dressing and a little ketchup, giving it a slightly different flavour and colour.
Can I buy Frisco sauce in the UK?
Steak n Shake does not currently operate restaurants in the UK, so the sauce is not sold in shops here. Making a homemade version is the easiest way to try it.
What can I use instead of french dressing?
If you cannot find french dressing, a mix of ketchup, a touch of paprika, and a little extra mayonnaise can create a similar tangy, sweet base.
How long does homemade Frisco sauce last?
Stored in a sealed container in the fridge, it typically lasts around one week, sometimes longer depending on the ingredients used.
