A delicious blend of fresh mushrooms, bacon, garlic and cream, Boscaiola Sauce is a rich and creamy sauce that you will be pouring on everything! And the good news is that it couldn't be easier to make.

This creamy classic is the perfect sauce to spoon over chicken or steak, or use it to create an indulgent pasta sauce, and everything in between.
I was inspired to make my own version of boscaiola sauce at home because my husband always seems to choose it from the menu if we are eating out. His current favourite (and mine) from a local eatery is crumbed chicken schnitzel, topped with creamy boscaiola and extra shaved parmesan on top. So. Good.

My top tips for the best result
- My tip for cream-based sauces is to turn the pan off when you think the sauce is slightly too thin and runny, this allows the sauce to cool just a little - and it should then come to the consistency you want. If it's still a bit loose, turn the heat back on for a minute or two and repeat. These types of sauces naturally thicken as they cool.
- If your sauce is too thick, you can thin it out with a splash of milk or water, or pasta-cooking water if you are serving this sauce with pasta.
Variations
Want to add more veggies? Stir through some baby spinach or frozen peas when you add the cream.
Add some fresh herbs, like finely chopped rosemary or thyme leaves.
Storage
Any leftovers of this boscaiola sauce can be kept in an airtight container in the fridge for up to 3 days.
Reheat the sauce in the microwave, adding a splash of water or milk as needed to thin it out.

Notes
- For cream-based sauces, turn the pan off when you think the sauce is slightly too thin and runny. This allows the sauce to cool just a little - and it should then reach the desired consistency. If it's still a bit loose, turn the heat back on for a minute or two and repeat. These types of sauces naturally thicken as they cool.
- If your sauce is too thick, you can thin it out with a small amount of milk or water, or some reserved pasta water if you are serving it with pasta.
