Baking Instructions

  • Preheat your oven to 180°C (350°F).
  • In a baking dish, add halved cherry tomatoes, minced garlic, 2 tbsp green pesto, xanthan gum (if using), and water. Mix until well combined.
  • Place halved chicken breasts on top of the tomato mixture. Spread additional green pesto over each piece of chicken.
  • Sprinkle grated cheese evenly over the chicken.
  • Prepare the topping by combining ground Brazil nuts, breadcrumbs (or keto substitute), olive oil, smoked paprika, salt, and pepper.
  • Spread the nut topping over the cheese layer.
  • Bake for 35 minutes or until the chicken is cooked through and the topping is golden and crisp.
  • Let the dish rest for 5 minutes before serving to allow the juices to settle.

Notes

  • Use keto-friendly alternatives like almond flour or pork rinds for a fully low-carb version.
  • Feel free to swap Brazil nuts with almonds or walnuts if needed.
  • Xanthan gum helps create a slightly thickened base but can be omitted.
  • This dish reheats well and is perfect for meal prep.
