What Makes This Recipe Truly Exceptional
This isn’t just another casserole; it’s a game-changer for anyone seeking delicious, healthy, and compliant meals. Here’s why this mushroom, chicken, and spiralized potato casserole will quickly become a family favorite:
- Incredible Texture with Spiralized Potatoes: Forget traditional pasta – spiralized potatoes offer a unique, satisfying texture that’s both hearty and delightful. They provide that comforting “noodle” feel while being packed with the nutritional benefits and robust flavor only potatoes can offer. It’s a brilliant way to enjoy your carbs in a new, exciting format.
- Luxuriously Creamy, Completely Dairy-Free: Prepare to be amazed! This dish achieves an astounding level of creaminess without a single drop of butter, heavy cream, or cheese. The secret lies in carefully selected ingredients and cooking techniques that deliver a rich, velvety sauce perfect for Whole30 and Paleo diets.
- Versatile for Any Occasion: Whether you need a quick and easy weeknight dinner solution or an impressive dish for a weekend gathering, this casserole fits the bill. Its robust flavors and comforting nature make it suitable for any meal, any day.
- Nutrient-Dense and Wholesome: Packed with lean protein from chicken, beneficial compounds from mushrooms, and wholesome carbohydrates from potatoes, this casserole is a truly balanced and nourishing meal. It’s free from common allergens and inflammatory ingredients, supporting your health goals without compromising on taste.
- Effortlessly Flavorful: Despite its gourmet taste, this recipe is designed to be straightforward. With a few key ingredients and simple steps, you can create a deeply flavorful dish that tastes like it took hours of intricate cooking.
Essential Recipe Ingredients
Crafting this savory casserole starts with selecting high-quality ingredients. Each component plays a crucial role in building the layered flavors and appealing textures that define this dish:
- Baby Bella Mushrooms: While white button mushrooms can work in a pinch, baby bellas (also known as cremini mushrooms) offer a deeper, more robust, and earthy flavor profile. This enhances the overall richness of the sauce, providing a more complex and satisfying taste.
- Potatoes: For the best spiralizing results and a lovely, creamy interior texture, I highly recommend using large gold potatoes. Their relatively firm flesh holds up well during spiralizing and baking, becoming perfectly tender without turning mushy.
- Freshly Ground Black Pepper: A generous amount of thick-ground black pepper is essential. It contributes a wonderful warmth and subtle kick that perfectly complements the creamy sauce and savory mushrooms. Don’t skimp on this!
- Garlic Powder: For convenience and consistent flavor, garlic powder is a fantastic addition. It blends seamlessly into the sauce, providing a foundational aromatic layer without the need for fresh mincing (though fresh garlic is used elsewhere in the recipe for added depth).
- Chicken: Opt for high-quality chicken breast or tenderloins. Cut into bite-sized pieces, they cook quickly and remain tender within the casserole, absorbing all the delicious flavors of the sauce. Ensuring good quality chicken makes a noticeable difference in the final dish.
- Onion and Garlic: These aromatic powerhouses form the base of our savory sauce. Freshly minced onion and garlic are sautéed to create a fragrant foundation, infusing the chicken and mushrooms with their essential flavors.
- Coconut Cream: The secret to our dairy-free creaminess! Not all coconut creams are created equal. I highly recommend Savoy coconut cream, specifically because it contains no preservatives and has a remarkably neutral flavor profile, tasting far less “coconutty” than many other brands. This allows the mushroom and chicken flavors to shine through beautifully.

Step-by-Step Cooking Instructions
Creating this delicious casserole is a simple process, broken down into four manageable steps. Follow these instructions closely for the best results:
Step 1: Partially Bake the Spiralized Potatoes. Begin by preheating your oven to 350°F (175°C). Carefully arrange your spiralized potatoes in a large oven-safe frying pan. Drizzle them with half a tablespoon of olive oil, then season generously with a quarter teaspoon of salt, a quarter teaspoon of black pepper, and a quarter teaspoon of garlic powder. Toss everything together to ensure the potatoes are evenly coated. Place the pan in the preheated oven and bake for 20 minutes. This pre-baking step ensures the potatoes become tender and slightly crispy, providing a wonderful base for the casserole. Once done, remove them from the oven and set aside in the pan.
Step 2: Expertly Brown the Mushrooms. While the potatoes are baking, heat another large frying pan over medium-high heat with half a tablespoon of olive oil. Add the sliced baby bella mushrooms to the pan and mix to coat them in the oil. Cook the mushrooms for approximately 15-20 minutes, stirring occasionally. You’ll notice they will first release their moisture (“sweat”), then this liquid will evaporate, and finally, they will begin to turn a beautiful golden brown. This browning process is crucial for developing deep, umami-rich flavors. The cooking time may vary depending on your pan size; larger pans cook faster. Once beautifully browned, remove from heat and set aside in the pan.
Step 3: Prepare the Flavorful Chicken. In a separate frying pan (or the pan used for mushrooms after removing them), combine half a cup of minced onion and one heaping tablespoon of minced garlic with half a tablespoon of olive oil. Cook over medium-high heat for about 3 minutes until fragrant. Add the bite-sized chicken pieces to the pan. Season the chicken with a quarter teaspoon of salt, a quarter teaspoon of ground black pepper, and half a teaspoon of Herbes de Provence. Mix well and cook for about 5 minutes, stirring frequently, until the chicken is lightly browned and mostly cooked through. Set the chicken aside.
Step 4: Assemble and Finish the Casserole. Bring the pan of cooked mushrooms back to medium-high heat. Add one cup of Savoy coconut cream, three-quarters of a teaspoon of black pepper, and half a teaspoon of salt. Incorporate the cooked chicken into the mushroom mixture, making sure to scrape in all the delicious minced garlic and onion from the chicken pan. Stir everything together thoroughly and bring to a gentle boil for approximately 3 minutes, allowing the sauce to thicken slightly and flavors to meld beautifully.
Finally, pour this creamy, rich mushroom and chicken mixture evenly over the pre-baked spiralized potatoes in their pan. Return the entire pan to the oven and bake at 350°F (175°C) for another 15 minutes. For an extra touch of golden-brown perfection, switch your oven to the broiler setting for a few minutes at the end. Keep a very close eye on it during this step to prevent burning! Serve immediately and enjoy this wholesome, satisfying casserole.
Expert Tips for Casserole Perfection
Achieving the best possible casserole experience means paying attention to a few crucial details. These tips will help you elevate your dish from good to absolutely outstanding:
- Spiralizer Blade Choice and Cooking Times: The thickness of your spiralized potatoes significantly impacts cooking time and texture. This recipe specifically calls for the “chipper” or “chipping blade” from a Paderno Spiralizer, which yields thicker, more pasta-like strands. If you use a different blade that produces thinner strands, reduce the initial baking time for the potatoes to prevent them from becoming overcooked or mushy. Always test for tenderness.
- Selecting the Right Coconut Cream: The quality and flavor of your coconut cream are paramount for a delicious dairy-free sauce. Many brands can impart a strong coconut flavor, which might not be desired in a savory dish. I cannot stress enough the importance of using a good quality, preservative-free coconut cream that you genuinely enjoy the taste of. Savoy coconut cream is my top recommendation, as it has a clean, mild flavor that blends beautifully into savory applications.
- Proper Mushroom Browning: Don’t rush the mushroom cooking process! It’s essential to allow them to “sweat” thoroughly. This means they will release a lot of water, then that water needs to evaporate completely before they start to brown. Patience here is key; fully browned mushrooms develop a deep, umami-rich flavor that significantly contributes to the overall deliciousness of the casserole. If they don’t brown properly, they can taste watery and lack depth.
- Seasoning Throughout: Season your ingredients at various stages of cooking – the potatoes, the mushrooms, and the chicken. This layering of seasoning ensures that every component of the casserole is flavorful, rather than just relying on the final sauce.
- Oven-Safe Pan: Using a single oven-safe frying pan (like a cast-iron skillet or a T-FAL 12 inch oven safe pan) for both the stovetop cooking and baking simplifies the process and reduces dishwashing. This casserole is designed to be a one-pan wonder!
- Broiling for a Golden Finish: The final broil is optional but highly recommended for a beautiful, slightly crispy top layer. It adds a lovely textural contrast. Just remember to watch it very closely, as broilers can quickly turn food from golden to burnt.

55 mins
Ingredients
- 1 1/2 Tbs olive oil, divided
- 16 ounces baby bella mushrooms, sliced
- 3 medium potatoes, spiralized (yields approx. 5 cups spiralized potatoes – recommend using the Chipper/Chipping Blade of a Paderno Spiralizer for best texture)
- 1 tsp salt, divided
- 1 1/4 tsp black pepper, divided
- 1/4 tsp garlic powder
- 1 pound chicken tenderloins, cut into bite-sized pieces
- 1/2 cup minced onion (approx. 1/2 of a medium onion)
- 1 heaping Tbs minced garlic (approx. 4 cloves)
- 1/2 tsp Herbes de Provence (or 1/4 teaspoon thyme and 1/4 teaspoon rosemary)
- 1 cup canned coconut cream, without preservatives (Savoy is highly recommended for best flavor)
Instructions
- Preheat the oven to 350°F (175°C). This casserole is prepared in four main steps.
Step 1: Bake the Spiralized Potatoes.
- Spiralize your potatoes using the Chipper/Chipping Blade of a Paderno Spiralizer for thicker strands.
- Place the spiralized potatoes into a large oven-safe frying pan (such as a T-FAL 12 inch oven safe pan). Drizzle with 1/2 Tbs olive oil, 1/4 tsp salt, 1/4 tsp black pepper, and 1/4 tsp garlic powder. Mix thoroughly to coat. Bake in the preheated oven for 20 minutes. Remove from oven and set aside in the pan. While potatoes are baking, proceed to Step 2.
Step 2: Start Cooking the Mushrooms.
- In a separate large frying pan, heat 1/2 Tbs of olive oil over medium-high heat. Add the sliced baby bella mushrooms and mix them into the oil. Cook for 15-20 minutes, stirring occasionally, until they are golden brown. The mushrooms will first release moisture, which will then evaporate before they begin to brown. Adjust cooking time based on pan size; a larger pan will cook them faster. Once browned, remove from heat and set aside in the pan.
Step 3: Prepare the Chicken.
- In a clean frying pan, combine 1/2 cup minced onion, 1 heaping Tbs minced garlic, and 1/2 Tbs of olive oil. Cook over medium-high heat for 3 minutes until fragrant. Add the bite-sized chicken pieces to the pan. Season with 1/4 tsp salt, 1/4 tsp ground black pepper, and 1/2 tsp Herbes de Provence. Mix well and cook for 5 minutes, stirring often, until the chicken is lightly cooked. Set the chicken aside.
Step 4: Put It All Together.
- Return the pan of cooked mushrooms to medium-high heat. Add 1 cup of coconut cream, 3/4 tsp of black pepper, 1/2 tsp of salt, and the cooked chicken (ensure all minced garlic and onion from the chicken pan are added). Mix everything together thoroughly and bring to a gentle boil for about 3 minutes to allow flavors to meld.
- Pour the creamy mushroom chicken mixture evenly on top of the baked spiralized potatoes in their pan. Return the pan to the oven and bake for 15 minutes at 350°F (175°C). For a golden-brown finish, set your oven to broil for a few additional minutes, watching carefully to prevent burning. Serve hot and enjoy your delicious Whole30/Paleo casserole!
Notes
- Cooking times for spiralized potatoes are dependent on their width. Using a “chipper” blade for thicker strands, as recommended for a Paderno Spiralizer, provides a pasta-like texture. Adjust baking time if using a thinner blade.
- The choice of coconut cream is crucial for the overall flavor. Opt for a high-quality brand like Savoy coconut cream, known for its neutral taste and lack of preservatives, to ensure the casserole’s savory notes truly shine.
- Properly browning your mushrooms is vital for developing rich, deep flavors. Ensure they “sweat” (release moisture) and that the liquid fully evaporates before they begin to caramelize and turn golden brown.
