Wholesome Ingredients for This Paleo Chicken Casserole

Each ingredient in this easy paleo chicken recipe was chosen for its health benefits and flavor. Here’s a closer look at a few key components:

• Chicken breasts: A lean source of protein that’s versatile and satisfying. For convenience, pre-cooked chicken or rotisserie chicken works wonderfully.
• Mushrooms: Rich in antioxidants, vitamins, and minerals, mushrooms bring an earthy flavor and meaty texture to the dish.
• Zucchini: A low-carb, fiber-rich replacement for traditional pasta. Choose smaller zucchinis for less water content and firmer “noodles.”

Substitution Tips: Don’t have zucchini? Swap with spaghetti squash or use sautéed spinach. Almond butter can replace cashew butter for a slightly nuttier sauce.

Ingredients for Paleo Chicken Casserole

• 2 medium chicken breasts (cubed)
• 2 Tbsp avocado oil
• 1/2 small yellow onion (chopped)
• 16 oz. mushrooms (sliced)
• 2 medium zucchini (spiralized into noodles)
• 1 tsp garlic powder

• 3/4 cup unsweetened almond milk
• Salt and pepper (to taste)

How to Make Paleo Chicken Casserole

1. Preheat your oven to 375°F (190°C).
2. Season chicken breasts with salt, pepper, and your desired spices. Bake on a lined sheet for about 30 minutes until fully cooked.
3. While the chicken cooks, heat avocado oil in a skillet over medium-high heat. Sauté the onions and mushrooms for 7-10 minutes, or until the mushrooms are caramelized and tender.
4. Spiralize the zucchini into noodles and gently cook in the skillet with the mushrooms for 5-7 minutes. Do not overcook to prevent sogginess.
5. In a mixing bowl, whisk together garlic powder, cashew butter, almond milk, salt, and pepper until smooth and creamy.
6. Take the chicken out of the oven and let cool slightly. Cube into bite-sized pieces.
7. Combine the cubed chicken, cooked veggie mixture, and cashew butter sauce in the skillet. Stir to coat evenly.
8. Top with grated vegan cheese and crushed walnuts, if using. Transfer the skillet to the oven and bake for 10 minutes.
9. Remove, serve hot, and enjoy every creamy, nourishing bite!
