The Best Way to Flavor Roast Chicken

Flavored and non flavored whole chicken

Since whole chicken can be flavorless, I like to stuff it with fresh thyme, sage, rosemary, lemon, onion, and garlic. I simply add salt and pepper and a little lemon zest for seasoning.

To get the chicken skin nice and crispy, I take a pastry brush and coat the chicken with a thin layer of oil.

So, when roasting, the skin will turn a nice golden brown and get extra crispy. I skip the basting, as I want the vegetables to absorb all the delicious juices.

Making Keto Gravy

When the roasted chicken is done cooking, I put it aside to rest as I make the keto gravy.

Since the vegetables absorbed most of the drippings, you’ll want to use chicken stock to make your gravy.

You’ll need to combine butter, tapioca flour, and chicken broth over a hot pan and cook for 1-2 minutes.

For the Chicken:

  • One 6-pound whole chicken 
  • 1 ½ lemon, cut into half
  • 1 ½ onion, cut into quarters
  • 1 garlic clove, cut in half
  • 8-10 sprigs of herbs such as thyme, rosemary, and sage
  • 1 ½ tablespoon of kosher salt
  • 1 ½ tablespoon of black pepper

For the Vegetables:

  • 1 ½ yellow onion, sliced
  • 620g of brussels sprouts
  • 590g of radishes
  • 3 teaspoons of olive oil (or avocado oil)
  • 3 teaspoons of salt
  • 3 teaspoons of pepper


Putting chicken inside an oven
  1. Preheat the oven to 425ºF and place the oven rack on the lower third shelf.
  2. Take out the gizzards and rinse the outside and inside with water. Once clean, use paper towels to pat the chicken completely dry. If any water is left, the skin won’t crisp. Place the chicken on a cutting board and adjust to room temperature.
  3. Prepare your vegetables by cutting the radish and Brussel sprouts in half and slicing the onions.
  4. Grab your cooking dish (could be a roasting pan, cast iron skillet, or glass baking dish) and place the vegetables inside. Ensure the layer is even, then drizzle with three teaspoons of oil, salt, and pepper. 
  5. Take the onion, lemon, garlic, and fresh herbs and stuff them inside the chicken. Brush the outside of the chicken with a thin layer of oil and season with salt and pepper. Put the chicken on top of the vegetables inside your cooking dish.
  6. Roast the chicken for 60-90 minutes. The outside should be crispy and golden. You’ll know the roasting chicken is finished when it reaches 165ºF (use a meat thermometer to check the temperature). It usually takes about an hour [1].
  7. Remove the roasted chicken from the oven, tilting it so the pan juices cover the vegetables. Let it rest for 10 minutes. 
  8. Place the vegetables back inside the oven and let cook for a further 20 minutes. 
  9. To serve, carve the chicken and serve warm with roasted vegetables. Pour the keto gravy and enjoy.

Can You Use Chicken Breasts Instead of a Whole Chicken?

Yes, you can use chicken breasts instead of a whole chicken. However, if you’d like to substitute whole chicken with chicken breast or chicken thigh in some keto chicken recipes, you’ll have to adjust the cooking time accordingly. Both the thigh and the breast take less time to cook than an entire chicken.

How Do You Marinate Chicken?

You marinate chicken by mixing your marinate ingredients inside a small bowl. This usually consists of garlic powder, lemon juice, soy sauce, and other ingredients.

Place the meat inside of ziplock bag and shake to coat. Refrigerate the mixture for 4 - 6 hours for best results.
