The Secret to a Creamy Dairy-Free Sauce

Achieving a rich, creamy sauce without cream or cheese is all about blending wholesome ingredients: creamy coconut milk, chicken broth, and a touch of starch for thickening. Add in aromatic garlic, onion, and fresh herbs for flavor that’s anything but basic. The result is a silky, fragrant sauce that perfectly hugs every bite of chicken and potato.

Effortless Assembly for the Best Casserole

After mixing the velvety sauce, simply toss together diced chicken, potatoes, and onions, layering everything in a casserole dish. Pour the sauce over for even coating and bake until everything is golden, creamy, and bubbling. This hands-off cooking method lets flavors blend for a truly satisfying result with minimal effort.

Instructions

1. Preheat your oven to 400°F (200°C). Lightly grease a 9×13 inch casserole dish with 1 tbsp oil.
2. In a large bowl, toss cubed chicken, potatoes, and onion with remaining 2 tbsp oil, half the salt and pepper, and the dried thyme and parsley. Spread evenly in the casserole dish. If using greens, layer them in now.
3. In a medium saucepan, whisk together the coconut milk, chicken broth, garlic, and 2 tbsp arrowroot starch over medium heat. Simmer 2–3 minutes until slightly thickened.
4. In a small bowl, mix the last 1 tbsp arrowroot starch with 2 tbsp cold water to form a slurry. Slowly whisk this into the saucepan. Continue to stir until the sauce is creamy and smooth, about 1–2 minutes. Season with remaining salt and pepper.
5. Pour the sauce evenly over the chicken and potatoes. Gently toss to distribute.
6. Bake uncovered for 40–45 minutes, until potatoes are fork-tender and casserole is bubbling. If desired, broil the top for 2–3 minutes for a golden finish.
7. Let cool for 10 minutes before serving. Garnish with fresh parsley and enjoy!
