Shepherd’s pie is probably my all-time favorite winter casserole. It’s simple and takes no more than 45 minutes to put together. You can enjoy half the recipe now and freeze the other half for later.
So, with Thanksgiving 1 week away, I officially have my first dish made (happy dance).
Let me start by saying, this is a versatile recipe. You can use any ground meat you like: turkey, bison, beef, or lamb (even french lentils for a vegan version). I opted for grass fed beef and lamb.
Rosemary compliments the flavor of the lamb and stands up against the sweetness of the yams. Then there’s peas, carrots, mushrooms and bone broth, making for one nutritious meal!
While I love a good Thanksgiving sweet potato casserole as much as the next person, I thought I’d offer a savory way to make use of the gigantic yams that are in season. Now, if you don’t like the sweetness of yams, feel free to top instead with herb infused mashed potatoes.
Can you freeze shepherd’s pie?
Yes! Making this the perfect Thanksgiving make-ahead dish!
Freezer instructions: After assembling, wrap the dish tightly with plastic wrap and place in the freezer up to 1 month. Reheat from frozen (covered tightly with foil) for approx. 2 hours in a 370 ºF oven or until warmed through.
How to Make Sweet Potato Shepherd’s Pie – Step by Step
Get all the prep work done first – chop the mushrooms, onion, garlic, and carrot then sweat the onion, garlic, carrot, and peas in a skillet (photos 1 & 2).
Stir in the mushrooms and cook until softened. In a separate pan cook the ground beef and lamb, stirring in the tomato paste (pictures 3 & 4). While the filling cooks, you can peel and cut the yams into large chunks (photo 5).
Spread the filling into a baking dish and top with a layer of sweet potato. Bake or wrap and freeze for later (photo 8).
I serve this shepher’s pie just as it is for a complete meal but if you wanted to add a light lemon and olive oil kale salad, that would be great too!
Top Tips for Making Sweet Potato Shepherd’s (Cottage) Pie
- When chopping the vegetables, aim for roughly the equal size cuts. I prefer medium size pieces, slightly larger than a pea.
- Don’t overfill your pan when sweating or it will take longer to cook. This is a large recipe so works best with 1 pan for the veg and 1 pan for the meat.
- You can peel and simmer the yams while the vegetables/meat cook.
- You can prepare the entire pie and refrigerate for baking same day or freeze and reheat from frozen.
- If cooking for 1-2 people, you can distribute the recipe into as many baking dishes as you like, or use ramekins for single-serve meals – great for meal prep!
- It’s easier to mash the sweet potatoes if they are very tender and still warm.
- If you are looking to up the nutritional value of this dish even more, you could add up to 4 oz of chopped liver, a great way to enjoy the benefits of organ meat!
