Look, we all love a fancy meal, but who has time to stand over a stove stirring things like we’re in a French bistro? Not me. That’s why this slow cooker creamy tarragon chicken is a total game-changer.

It’s rich, indulgent, and full of flavour, yet somehow feels like a cheat code because the slow cooker does all the hard work.

You just chuck in some chicken, a splash of white wine (no judgement if you take a sip first), a good dollop of crème fraîche, and of course, tarragon – the real MVP here.

The result? Tender, melt-in-the-mouth chicken smothered in a creamy, herby sauce that’ll have you licking your plate.

Slow cooker tarragon chicken is great for meal prep, perfect for impressing dinner guests, and most importantly, it means you can go and binge-watch your latest TV obsession while dinner takes care of itself.

What is Slow Cooker Creamy Tarragon Chicken?

Slow Cooker Creamy Tarragon Chicken is a classic French-inspired dish that’s been made outrageously easy. Instead of standing at the stove, you let the slow cooker do the magic, infusing the chicken with a creamy, tarragon-infused white wine sauce.

Tarragon is the secret weapon here – a slightly aniseedy herb that brings a touch of French flair to your plate. Combined with Dijon mustard, white wine, and crème fraîche, the sauce becomes silky, tangy, and utterly divine.

It’s high in protein (so you can pretend you made it for ‘health reasons’) and perfect for batch cooking – meaning leftovers taste even better the next day.

Tarragon Chicken Key Ingredients

Chicken Breasts. Lean, high in protein, and perfect for soaking up all that creamy goodness.

Garlic. Because no respectable dish skips garlic. It's the law.

Onion. Adds a subtle sweetness and makes your kitchen smell amazing.

Dry White Wine. For the sauce, not just for sipping (though no judgement if you multitask).

Chicken Stock. Brings everything together in a savoury, flavour-packed bath.

Tarragon. The star of the show. Slightly aniseedy, totally delicious, and very fancy-sounding.

Dijon Mustard. Adds a little tang and a bit of heat. Basically, it makes everything better.

Cornflour. The secret weapon for a thick, velvety sauce. No one likes a watery disaster.

Crème Fraîche. The finishing touch for that rich, creamy, slightly tangy sauce.

Instructions

Heat olive oil in a pan over medium-high heat. Season the chicken with salt & pepper and sear for 2 minutes per side until lightly golden (don’t cook through). Transfer the chicken to the slow cooker.

In the same pan, add onion and cook for 2 minutes, stirring. Add garlic and cook for another 30 seconds until fragrant. Pour in the white wine and let it simmer for 2-3 minutes, stirring, until reduced by half. Deglaze by scraping up any browned bits for extra flavour. Transfer the onion-wine mixture to the slow cooker.

Add chicken stock, tarragon, and Dijon mustard, salt, some more pepper and the cornflour. Cover and cook on LOW for 4 hours or HIGH for 2 hours, until the chicken is tender.

Stir in the crème fraiche and mix well.

Serve & Enjoy!
