This easy high-protein chicken recipe is a great low-carb dinner option in under 30 minutes! It's a recipe adapted from the Creamy Tarragon Chicken with Cabbage & Crispy Bacon from my latest cookbook, The New Mediterranean Diet.

We've got juicy and tender chicken thighs cooked with mushrooms, onions, garlic, lemon and tarragon, and finished with some creme fraiche.

Recipe Tips

We are serving it with some steamed asparagus which won't take more than 3 to 5 minutes to cook. Apart from asparagus, you could use other vegetable sides such as green beans, zucchini noodles or cauliflower rice.

If you're not low-carb, or making this for the whole family, you can serve it with some pasta or even rice.

Xanthan gum in this recipe acts as a thickener. If you're sensitive to xanthan gum, try glucomannan powder or skip the thickener altogether. Reducing the sauce further (cooking without a lid for a few more minutes) will thicken it more.

For a lower fat option, swap the creme fraiche with cream cheese or reduced fat sour cream. You can also use chicken breasts instead of thighs although the difference won't be significant.

Ingredients (makes 4 servings)

  • 2 tbsp virgin avocado oil or olive oil
  • 1 small yellow onion (70 g/ 2.5 oz)
  • 2 cloves garlic, minced
  • 1 kg skinless and boneless chicken thighs (2.2 lbs)
  • 3/4 tsp sea salt, or to taste
  • 1/4 tsp black pepper
  • 2 cups brown mushrooms, sliced (144 g/ 5 oz)
  • 2 tbsp fresh lemon juice (30 ml)
  • 1 cup chicken stock (240 ml/ 8 fl oz)
  • 1 cup creme fraiche or sour cream (240 g/ 8.5 oz)
  • Optional: 1/2 tsp xanthan gum or glucomannan powder
  • 2 tbsp chopped tarragon
  • 600 g trimmed asparagus, to serve (1.3 lbs)

  2. Meanwhile, cut the chicken thighs into small chunks. Season with salt and pepper. To the skillet with the browned aromatics add the chicken and cook for about 5 minutes, until opaque from all sides. Creamy Low-Carb Tarragon Chicken
  3. Add the sliced mushrooms, lemon juice and chicken stock. Stir to combine and bring to a boil. Once boiling, reduce to medium and cover with a lid. Cook for about 10 minutes, until the chicken is tender and cooked through. Creamy Low-Carb Tarragon Chicken
  4. Add the creme fraiche (or sour cream) and stir to combine. Cook uncovered over a medium-high heat for another 5 minutes, or longer if you wish to reduce the sauce and thicken.
    Note: You can optionally thicken the sauce with 1/2 tsp xanthan gum or glucomannan powder. To do that, simply sift over the surface using a fine mesh sieve while stirring to prevent clumps from forming. Creamy Low-Carb Tarragon Chicken
  5. Take off the heat and stir in chopped tarragon. Creamy Low-Carb Tarragon Chicken
  6. Serve while still warm with any low-carb vegetables of choice. Steamed asparagus, green beans, zucchini noodles or cauliflower rice work best.
  7. To store, let it cool down and refrigerate for up to 4 days. (Sauces with creamy dairy-based sauce don't freeze well as the sauce may split once reheated.) Creamy Low-Carb Tarragon Chicken

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Well it wasn't terrible, but its not good enough to make again.

I though it was delicious but I don't like tarragon so I used basil instead :-D Also no xanthan gum which was optional anyway.

Absolutely delicious! What can I say, we made this tonight for a quick weeknight dinner, exactly as written, and the only thing I skipped was the thickener because I don't enjoy the texture of xanthan gum in anything but baked goods. Glucomannan may have worked, but we were happy with the thinner sauce, and it's didn't matter one bit because it tasted sooooo good! Thank you so much, Martina, this is a fabulous recipe and I'm so as we have something new to add to our go-to weeknight meals now 😊

Thank you so much for your lovely feedback Anu!
