A wonderful comfort food casserole, with meal prep option, Paleo AIP Shepherd's Pie is nightshade-free, cozy and full of good for you gentle ingredients.
Prepare Mashed Parsnips recipe. (Don't make the topping from the recipe, unless you'd like that garnish on the casserole. Only complete through mashing the parsnips, Step 1 after the heading "Mashed Parsnips continued...") While parsnips are cooking, begin meat filling below.
In large sauté pan, add beef or lamb + 1 teaspoon sea salt. Cook over medium heat, breaking up meat with a spatula, until pink is gone, about 8 minutes. Cook another minute. Then, use a slotted spoon to remove meat to a bowl. Set aside.
If there's a lot of rendered fat, as is often the case with lamb, pour some of it off, and retain for another use. Keep about 2 Tablespoons rendered meat fat in the pan. If needed (with lean beef), add 1 to 2 Tablespoons avocado oil or other preferred fat as needed for next step: Add onion (or green beans for VAD) and celery to pan, with remaining 1/2 teaspoon sea salt. Sauté over medium heat 5 minutes. Add carrot (or parsnip) + herbs and ginger; reduce heat to medium low, and sauté 10 more minutes.
Preheat oven to 350° F.
Add meat back to pan, sautéing it into the veggies. Remove from heat. Transfer to casserole dish and spread out evenly. Use the back of the spatula or a spoon to flatten and press slightly, so meat filling is compressed a bit.
Top with completed Mashed Parsnips recipe. Smooth top surface. Optionally, use the tines of fork to create traditional Shepherd's Pie markings on the top surface. Bake in preheated oven about 40 minutes, until piping hot, crispy brown around the edges and perhaps bubbling out a bit at one corner.
