Béarnaise Mayo
This béarnaise mayo is a twist on the classic steak sauce. This makes a great burger or sandwich sauce & is flavoured with tarragon, mustard & lemon juice.

All the flavours of a classic béarnaise steak sauce, in a punchy mayonnaise!
This béarnaise mayo is packed with a whole load of flavour! There’s intense tarragon, tangy Dijon mustard & sharp lemon juice (to cut through the creamy mayo!). This stuff works great in steak sandwiches, in burgers with grilled meats & pan fried fish. It’s seriously tasty!

What You’ll Need
- Mayonnaise – Any mayo will work for this recipe. I used Hellmann’s! You could use homemade mayonnaise as well.
- Tarragon – Tarragon is used to flavour béarnaise sauce so it’s what we’re using for our mayo. You’ll need to pick the leaves from the stalks then finely chop them.
- Dijon Mustard – Mustard gives our mayo more depth of flavour. Make sure to use Dijon!
- Lemon Juice – Lemon juice adds acidity to our mayo, cutting through the creaminess.
How To Make Béarnaise Mayo
This mayonnaise is super easy to make & comes together in just a few minutes! To make, we simply mix together mayonnaise, Dijon mustard, lemon juice & chopped tarragon. We give the mayo a taste to check the seasoning then add in salt & pepper as needed.
Once mixed, béarnaise mayo can be used straight away or stored in the fridge for up to 3 days.
Serving Suggestions
Our béarnaise mayo is based on the classic steak sauce so goes great with beef, especially in a steak sandwich or a burger! However, béarnaise mayo will also work really well with other meats such as chicken & pork and fish, like salmon (pan fried!).
