Authentic Paleo Lamb Shepherd's Pie with Garlic Cauliflower Mash

Ingredients

For the Savory Lamb Filling:

• 2 lbs 100% grass-fed ground lamb
• 1 tbsp grass-fed ghee or avocado oil
• 1 large yellow onion, finely diced
• 3 medium carrots, diced into small 0.25-inch cubes
• 3 stalks celery, finely diced
• 4 cloves garlic, minced
• 2 tbsp organic tomato paste
• 1 tbsp organic coconut aminos
• 1 tsp Red Boat fish sauce
• 1 cup rich beef bone broth
• 1 tbsp fresh rosemary, finely chopped
• 1 tbsp fresh thyme leaves
• 1 tbsp arrowroot starch (dissolved in 2 tbsp cold water)
• 1.5 tsp coarse Celtic sea salt
• 0.5 tsp freshly ground black pepper

For the Creamy Garlic Cauliflower Mash Topping:

• 1 large head organic cauliflower (approx. 2 lbs), cut into florets
• 3 tbsp grass-fed clarified butter (ghee)
• 3 cloves roasted or steamed garlic
• 2 tbsp nutritional yeast (adds rich savory cheesy depth without dairy)
• 0.75 tsp coarse sea salt
• Fresh cracked black pepper and chopped chives (for garnish)

Step-by-Step Instructions

1. Steam Cauliflower: Place cauliflower florets and 3 cloves garlic in a large steamer basket over 1 inch of boiling water. Cover and steam for 10 to 12 minutes until completely fork-tender. Drain well and let steam dry for 2 minutes to eliminate excess moisture.
2. Puree the Mash: Transfer hot steamed cauliflower and garlic to a food processor or blender. Add 3 tbsp ghee, nutritional yeast, and 0.75 tsp sea salt. Blend on high for 60 seconds until silky, thick, and pillow-soft. Set aside.
3. Brown the Lamb: Heat 1 tbsp ghee in a large 12-inch oven-safe cast-iron skillet (or Dutch oven) over medium-high heat. Add ground lamb and cook for 6 to 7 minutes, breaking it into small crumbles with a wooden spoon, until browned. (Drain off excess fat if desired, leaving 1 tbsp).
4. Sauté Mirepoix: Add diced onion, carrots, celery, and minced garlic to the lamb. Sauté for 5 to 6 minutes until the vegetables soften.
5. Simmer Gravy: Stir in tomato paste, coconut aminos, fish sauce, chopped rosemary, thyme, 1.5 tsp sea salt, and black pepper. Cook for 2 minutes. Pour in 1 cup beef bone broth and the arrowroot slurry. Bring to a simmer and cook for 3 to 4 minutes until the gravy is glossy and thick.
6. Top & Broil: Spread the creamy garlic cauliflower mash evenly across the top of the lamb filling in the skillet. Use the tines of a fork to create rustic decorative ridges across the mash.
7. Bake to Golden Perfection: Bake in a preheated oven at 375°F (190°C) for 20 minutes until the filling bubbles at the edges. Turn the broiler on HIGH for 2 to 3 minutes to toast the cauliflower peaks to a gorgeous golden brown.
8. Rest & Serve: Let stand for 10 minutes to allow the layers to settle. Garnish with chopped fresh chives and serve in generous rustic squares.

Chef's Paleo Nutritional Science

Pasture-raised lamb is one of the densest dietary sources of bioavailable L-carnitine, zinc, and heme iron, accelerating oxygen transport to working skeletal muscle. Replacing high-glycemic white potatoes with sulfur-rich cruciferous cauliflower provides sulforaphane and indole-3-carbinol, supporting Phase II hepatic detoxification while stabilizing glycemic response.
