Ingredients for aip shepherd's pie
AIP-friendly ingredients that deliver classic comfort food flavor without restricted components.
| Ingredient | Amount | Notes |
|---|---|---|
| Green Lentils 🌱 | 1 ½ cups | Dried, rinsed thoroughly |
| Coconut Cream 🥥 | 13 ½ oz | Full-fat, canned (not carton) |
| Cauliflower Florets 🥬 | 2 cups | Fresh or frozen, chopped small |
| Coconut Oil 🫒 | ½ cup | Melted, for roasting |
| Coconut Milk 🥥 | 1 cup | Full-fat, canned (not carton) |
| Creamy Coconut Milk 🥥 | ½ cup | For cauliflower mash |
| Garlic Cloves 🧄 | 4 cloves | Fresh, minced finely |
| Creamy Tomato Sauce 🍅 | 1 cup | AIP-compliant, no nightshades |
| Mushrooms 🍄 | 8 oz | Cremini or white, sliced |
| Celery Stalks 🥬 | 2 whole | Diced finely for filling |
| Coconut Aminos 🧂 | 1 tbsp | For umami depth |
| Fresh Thyme 🌿 | ¼ cup | Chopped, or 1 tsp dried |
| Sea Salt 🧂 | 1 tsp | Fine grain preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Coconut Flour 🌾 | 2 tbsp | For binding cauliflower |
The green lentils are the protein backbone here—dried and rinsed thoroughly to avoid bitterness. Costco or bulk bins offer the best price for quality lentils, and they keep for up to 12 months in a cool, dark place. For mushrooms, cremini or white varieties provide the best umami without overpowering the dish. Trader Joe's often carries pre-sliced options, but fresh is ideal if you're willing to chop. The cauliflower should be fresh and bright white—avoid yellowing florets, which indicate age. Frozen works too if fresh isn't available, but thaw and pat dry before roasting to prevent excess moisture in your topping.
No coconut cream? Full-fat canned coconut milk works in a pinch, though the texture will be slightly thinner. Substitute with extra coconut milk (add 2 tbsp more) if needed. The creamy tomato sauce is non-negotiable for that classic shepherd's pie flavor—look for AIP-compliant brands like Primal Kitchen or make your own with coconut milk and fresh herbs. Fresh thyme is ideal, but dried at one-third the amount works if you're short on time. For the cauliflower topping, coconut flour is key for binding without gluten—Bob's Red Mill brand is widely available and reliable. Pre-grated Parmesan? Skip it entirely—this recipe avoids all dairy for strict AIP compliance.
Store leftovers in an airtight glass container for up to 5 days in the fridge, or freeze for 3 months for long-term meal prep. Reheat gently in the oven at 350°F to maintain the cauliflower topping's texture—microwaving can make it soggy. Portion before freezing for easy grab-and-go meals. The filling reheats beautifully, while the cauliflower topping benefits from a quick broil to crisp up the edges. Double the batch if you're feeding a crowd—this freezes exceptionally well and tastes even better the next day as flavors meld.

Step-by-step instructions for AIP shepherd's pie
Follow this method for a hearty yet compliant dish with a creamy cauliflower topping and savory lentil filling.
🍳 Step 1: Cook the Green Lentils Until Tender
In a medium saucepan, combine the 1.5 cups green lentils with 4 cups water (or enough to cover by 1 inch). Bring to a boil over medium-high heat, then reduce to a simmer. Cook uncovered for 20-25 minutes until the lentils are fork-tender but still hold their shape. Drain any excess liquid and set aside.
Here's the thing—lentils should be al dente, not mushy. If they're still firm after 25 minutes, add ¼ cup water and cook another 5 minutes. Overcooked lentils turn to paste, which ruins the filling texture. Season with ½ teaspoon sea salt and ¼ teaspoon ground black pepper while warm.
🍳 Step 2: Build the Savory Lentil Filling
In a large skillet, heat 0.5 cup melted coconut oil over medium heat. Add the 8 oz sliced mushrooms and 2 diced celery stalks, cooking for 5-6 minutes until softened. Add the 4 minced garlic cloves and 0.25 cup chopped fresh thyme, cooking for 30 seconds until fragrant.
Stir in the cooked lentils, 1 cup creamy tomato sauce, and 1 tablespoon coconut aminos. Simmer for 8-10 minutes until the mixture thickens slightly. The filling should be moist but not soupy—if too thin, simmer uncovered another 2 minutes. Season with remaining ½ teaspoon sea salt and ¼ teaspoon black pepper. Transfer to a greased 8x8-inch baking dish.
🥘 Step 3: Prepare the Cauliflower Topping
Preheat oven to 400°F. In a large skillet, heat 0.5 cup coconut oil over medium heat. Add the 2 cups cauliflower florets and roast for 10-12 minutes until golden and tender. Transfer to a food processor and add 0.5 cup creamy coconut milk, 2 tablespoons coconut flour, ½ teaspoon sea salt, and ¼ teaspoon black pepper. Pulse until smooth.
This is where texture matters. The topping should be creamy but pipeable—if too thick, add 1 tablespoon coconut milk; if too thin, add 1 teaspoon coconut flour. Spread evenly over the lentil filling, creating a smooth crust. Use a fork to create decorative ridges for browning.
🔥 Step 4: Bake Until Golden and Bubbling
Bake uncovered for 20-25 minutes until the topping is golden brown and the edges are crisp. The filling should bubble gently—this ensures proper cooking without drying out. For extra browning, broil for 2-3 minutes at the end, watching closely to avoid burning.
Here's the critical checkpoint: the internal temperature of the filling should reach 160°F. If unsure, let it rest 5 minutes before serving—the residual heat will finish cooking it. Garnish with extra thyme sprigs for freshness.
Pro Tips For Making Aip Shepherd'S Pie
- SOFTEN LENTILS RIGHT: Cook your green lentils until they’re tender but still hold shape—think al dente pasta, not mushy. Overcooking turns them into glue, and that’s when your pie starts falling apart. A quick taste test mid-cook saves you from mushy disappointment later.
- SAUTE CAULIFLOWER FIRST: Get those florets golden in coconut oil before adding anything else. I learned this the hard way—raw cauliflower soaks up coconut milk like a sponge, making the filling watery. High heat for 5 minutes first locks in flavor and texture.
- DON’T SKIP THE COCONUT CREAM LAYER: Spread a thin, even layer of coconut cream under the cauliflower top before baking. It acts as a glue and keeps the pie from drying out. Too thick? It’ll steam instead of crisp. Too thin? You’ll get sad, dry cauliflower. Aim for a whisper-thin coat.
- PRESS THE TOP HARD: After assembling, press the cauliflower florets into the filling with your palm—no gaps, no half-hearted patting. I used to rush this, and the pie would end up lopsided or undercooked in spots. A firm press guarantees even baking and a unified texture.
Make-ahead tips for this aip shepherd's pie
Prep Ahead Components
The lentil filling and cauliflower topping can be prepped separately up to 2 days in advance, making this a perfect meal prep dish. Cook the lentils first, then store them in an airtight container in the fridge.
The cauliflower mash can be made ahead too—just roast and blend it, then refrigerate until ready to assemble. This saves you 30-45 minutes of active prep time on busy weeknights. 💛
Assemble the Day Of
For the freshest texture, assemble the pie the morning you plan to bake it. Spread the pre-cooked lentil filling in your baking dish, then top with the chilled cauliflower mash.
This keeps the topping from getting soggy while you're preheating the oven. I like to let everything sit at room temperature for 10 minutes before baking to ensure even cooking.
Freezer-Friendly Filling
The lentil filling freezes exceptionally well for up to 3 months. Portion it into single-serving portions in airtight containers or freezer bags, then thaw overnight in the fridge before assembling your pie.
The cauliflower topping, however, doesn't freeze as well due to its texture—it's best made fresh or refrigerated for up to 4 days.
Baking in Advance
You can bake the entire pie 1 day ahead and store it in the fridge. Reheat it at 350°F for 15-20 minutes to restore the crispy topping. The flavors actually deepen overnight, making it even more comforting the second time around.
For a quick meal, this is a game-changer—just pop it in the oven and enjoy without any extra prep. ✨
Portion for Meal Prep
Divide the baked pie into individual portions before storing to make grab-and-go meals. Use a sharp knife to cut through the center, then wrap each portion in parchment paper before refrigerating.
This keeps the cauliflower topping from drying out and makes it easy to reheat just one serving when you need it. Perfect for busy mornings or lunches at work!
Reheating Tips
For the best results, reheat the pie in the oven at 350°F for 15 minutes—this helps crisp the cauliflower topping without drying out the filling. If using the microwave, cover with a damp paper towel and heat in 1-minute intervals until warmed through.
Avoid reheating in the microwave more than once, as it can make the topping soggy. 🔥

Frequently asked questions
Can I make this AIP shepherd's pie without lentils?
Yes! For a meat-free version, swap the lentils for 1.5 cups cooked chickpeas (rinsed well) or 1 lb finely chopped mushrooms sautéed with coconut aminos. If you're not strict AIP, you could also use ground turkey or beef cooked with AIP-compliant spices like thyme and garlic. The key is maintaining the savory texture contrast with the cauliflower topping.
Why does my cauliflower topping turn out watery?
This usually happens when the cauliflower isn't fully drained after roasting or the coconut flour isn't properly incorporated. First, ensure you pat the roasted cauliflower dry with a clean towel before blending. Then, pulse the coconut flour in 2 batches while blending to avoid clumping. If it's still too thin, add 1 extra teaspoon coconut flour and blend again.
Can I use sweet potatoes instead of cauliflower for the topping?
Sweet potatoes work beautifully and add natural sweetness that pairs well with the savory filling. Use 1.5 cups peeled and diced sweet potatoes (roasted instead of steamed) and blend with 0.25 cup coconut milk and 1 tablespoon coconut flour. The texture will be slightly denser but still creamy. Roast at 400°F for 15-20 minutes until golden.
How do I prevent cross-contamination with AIP ingredients?
Use separate prep surfaces and utensils for AIP ingredients (like coconut oil and cauliflower) versus any non-AIP items in your kitchen. Wash cutting boards, knives, and bowls thoroughly with hot soapy water between uses. For extra caution, designate a specific area of your counter for AIP prep or use disposable parchment paper as a clean surface. Always cook AIP dishes last if sharing kitchen space.
Can I make this recipe in a slow cooker?
While not traditional, you can adapt it! Cook the lentil filling in your slow cooker on Low for 4-5 hours or High for 2-3 hours, then transfer to a baking dish. For the topping, spread the cauliflower mash on top and bake at 400°F for 15 minutes to crisp it. The slow cooker method works best for the filling only—don't try to cook the topping in it.
