Ingredients
Biscuit Topping
- 1/2 cup heavy whipping cream
- 1 tbsp white vinegar
- 1 cup Wholesome Yum Superfine Almond Flour
- 1/4 cup Wholesome Yum Coconut Flour
- 1/2 tsp pink salt
- 1 tbsp gluten-free baking powder
- 2 large eggs
- 4 tbsp unsalted butter (melted)
Filling
- 4 tbsp unsalted butter
- 1 cup onion (1/2 of a medium onion, diced)
- 1 large stalk celery (diced)
- 1 large carrot (diced)
- 3 cloves garlic (minced)
- 1 tbsp poultry seasoning
- Pink salt (to taste)
- Cracked black pepper (to taste)
- 1 lb boneless skinless chicken thighs (cubed)
- 1 cup heavy whipping cream
- 1/2 cup chicken bone broth
- 1 tsp ground thyme
- 1 tsp rubbed sage
- 1/2 tsp xanthan gum
- 1/2 cup frozen peas
- Fresh flat-leaf parsley (chopped for garnish)
Instructions
- Prepare the biscuit topping: Stir the vinegar into the heavy whipping cream and set aside for 10 to 15 minutes to allow it to thicken and curdle slightly, creating a keto-friendly buttermilk substitute.
- Mix dry ingredients: In a large bowl, whisk together the almond flour, coconut flour, pink salt, and gluten-free baking powder until well combined.
- Add wet ingredients: Add the eggs, prepared heavy cream mixture, and melted butter to the dry ingredients. Whisk thoroughly until a smooth batter forms. Set the biscuit dough aside.
- Preheat oven and start filling: Preheat your oven to 350 degrees Fahrenheit. Heat the butter in a large skillet over medium heat.
- Sauté vegetables and seasonings: Once the butter has melted, add diced onion, celery, carrot, minced garlic, poultry seasoning, salt, and cracked black pepper. Cook, stirring occasionally, until vegetables begin to soften, about 5 minutes.
- Cook chicken: Add the cubed chicken thighs to the skillet. Season again with salt and pepper, then sauté until the chicken is fully cooked, about 5 to 7 minutes.
- Add sauce ingredients: Stir in the heavy cream, chicken bone broth, ground thyme, rubbed sage, and xanthan gum. Bring the mixture to a boil over medium-high heat, then reduce to low and let simmer for 5 minutes to thicken the sauce.
- Adjust seasoning and add peas: Taste the filling and adjust salt and pepper as needed. Stir in the frozen peas and simmer for an additional 2 minutes before removing from heat.
- Add biscuit topping: Using a cookie scoop lightly sprayed with olive or coconut oil, drop scoops of the biscuit dough evenly over the surface of the hot filling. Spread the dough gently with a spatula or your fingers to slightly flatten.
- Bake the casserole: Place the skillet or transfer to a baking dish and bake for 30 to 35 minutes, or until the biscuit topping is golden brown and springs back lightly when touched.
- Cool and garnish: Let the casserole cool for 10 to 15 minutes to set. Before serving, sprinkle with chopped fresh flat-leaf parsley for a bright, fresh finish.
Notes
- The xanthan gum helps thicken the sauce without adding carbs.
- Make sure to use bone broth that is low in sodium to control the salt content.
- If you prefer, swap the chicken thighs for chicken breasts but ensure they are cooked through.
- Use gluten-free baking powder to keep the recipe keto-friendly and gluten-free.
- Scooping the biscuit dough with a cookie scoop ensures even topping portions and helps them bake uniformly.
- Allowing the cream and vinegar mixture to sit creates a perfect acidic environment for the biscuits to rise and tenderize.
