Instructions

Preheat your oven to 375 degrees F.
In a large oven-safe skillet or casserole dish, heat olive oil over medium heat.
Add the chopped onion and sauté for 3-4 minutes until translucent.
Add the minced garlic and cook for another 30 seconds until fragrant.
Add the chicken pieces to the skillet and cook for 5-6 minutes, stirring occasionally, until they start to brown and are mostly cooked through.
Add the cauliflower florets, stirring to combine evenly with chicken and aromatics.
Sprinkle the dried thyme, oregano, smoked paprika, salt, and pepper over the mixture.
Pour in the gluten-free chicken broth and unsweetened almond milk, stirring to combine all ingredients.
Bring the mixture to a gentle simmer and cook for 5 minutes to allow flavors to meld.
If using nutritional yeast, sprinkle it evenly over the top and stir gently.
Transfer the skillet or dish to the preheated oven and bake uncovered for 15 minutes, until the cauliflower is tender and the top is lightly browned.
Remove from oven and let rest for 5 minutes before serving.
Garnish with chopped fresh parsley if desired, then serve warm.
