This is one of those dishes that once on the plate, looks (and tastes!) like it was a lot more effort to make than it really was. Slow Cooker Tarragon Chicken is a great recipe when you have guests and are looking for something a little bit special to serve.
It works just as well when you feel like eating something delicious and comforting yourself!

What Is The Flavour Of Tarragon?
Tarragon is a mix of vanilla and aniseed, and as such adds a beautiful sweet taste to any dish it’s used in.
Tarragon is a staple herb in French cooking, and with good reason. It’s aromatic, fresh tasting and compliments a variety of produce where delicate seasoning is required, such as chicken, fish and eggs.
What To Serve With Slow Cooker Tarragon Chicken?
Green vegetables are always a winning combination with Tarragon Chicken. You could use:
- Green beans
- Asparagus
- Broccoli
Also – obviously not a vegetable – but we love to serve a few slices of crusty bread for mopping up any leftover sauce!

Can I Freeze Leftover Crockpot Tarragon Chicken?
Leftovers (if you have any!) can be kept in an airtight container in the fridge for up to three days, or a month in the freezer.
When reheating, ensure that the tarragon chicken is piping hot all the way through before serving. Cook fresh vegetables to serve alongside it.

Hi, what's the reason for not using greek style yoghurt? Just curious! Love your other recipes, looking forward to seeing how this one turns out in a few hours

Hi Adam, we use natural yoghurt as it is thinner and is absorbed by the porridge better than Greek which is thicker.

Have just made this, and will definitely make it again. I couldn’t buy fresh tarragon so had to use dry. I put in one heaped desert spoonful as I also had halved the recipe for two people. Maybe next time would use a little more. It was very delicious. Thank you for this recipe.

How long would you cook on low if using chicken breasts?

Chicken breasts need less time as they have a lower fat content. They will be cooked in 2.5 - 3 hours on high so check they are cooked through at 4 hours if cooking on low. This does depend on the slow cooker though as there are variances in the speed in which they cook.

Loved this. Wonderful herbs and meat which falls apart. I'll definitely use this recipe again.
By the way, Yvette's question was one which I had too, so it was good to see it had already been asked and answered!
