Creamy Peppercorn Sauce (Perfect For Steak)
An insanely delicious peppercorn sauce recipe infused with stock and creme fraiche for the best steak sauce ever. Let’s get cooking…

Who doesn’t love steak with homemade peppercorn sauce? It’s my go-to dinner recipe that turns home cooking into restaurant standard, and yes, it impresses everyone!
Not only is it perfect for pouring over steak, but I also like to pour it over chips, chicken and pretty much everything in my sight. Unlike most peppercorn sauce recipes, my one has a little twist, I make it using creme fraiche instead of cream, and I think it tastes way better!
I bought all the ingredients to make this creamy sauce from HelloFresh (including the peppercorns)! That’s why it’s been so easy to make from start to end (you can find out more in my HelloFresh review).


Crème Fraîche Steak Sauce
This sauce does look a little fancy, but trust me, it’s actually very easy to make and put together (I promise). The ingredients I’ve used are quite basic and the recipe is super easy too. I’m not joking when I say this sauce will change your life.
I chose not to include alcohol (like brandy) in my sauce, which means there’s no need to burn it off by igniting it into a flame. This makes the recipe even simpler to make and using creme fraiche instead of creme makes the sauce even creamier.
Recipe Ingredients

Below are the 5 ingredients I used to make this recipe (FYI, all my ingredients came from my HelloFresh box):
- Onion: I used a red onion, but you can also use shallots or white onions. I diced the onions into small square chunks.
- Black Peppercorns: To make the peppercorn sauce, whole black peppercorns are crushed. You can buy cracked black pepper or crush whole peppercorns yourself using a pestle and mortar.
- Stock: I used chicken stock paste, but you can use any stock like beef stock. The stock paste is mixed with water and left to reduce until thickened. You could also buy stock in liquid form rather than dissolving the paste in water.
- Creme Fraiche: If you don’t have creme fraiche you could also make the peppercorn sauce with double cream.
- Salt: I added salt for flavour.
How To Make Creamy Peppercorn Sauce (With Creme Fraiche)
Here’s a summary of how I make this peppercorn sauce. You can get the full recipe instructions on the recipe card below:
Step One:

I start by crushing the peppercorns into small pieces. As I’m also making steak, I season it with salt and black pepper before frying it.
To crush the peppercorns, I either place it in a sandwich bag and gently bash it with a rolling pin or achieve the same result in a pestle and mortar.
