Yes, I realize a lot of you are still looking for Thanksgiving Recipes, but in the weird world of food blogging I’ve already tested a few recipes for leftover turkey and fallen in love with this Leftover Turkey Shepherd’s Pie Casserole with Garlic-Parmesan Cauliflower Topping.  The days we sampled this recipe my nephew and cooking assistant Jake kept saying “This is really good” every time he took a bite.

The recipe uses turkey gravy, but if you don’t have any leftover gravy from Thanksgiving, you really should buy some gravy (like we did!) and give this recipe a try. And this is definitely a more carb-conscious version than the usual Shepherd’s Pie Recipes you’ll find, even with the purchased gravy!

Cut up the cauliflower and cook with the garlic cloves for 12-15 minutes in boiling salted water. Drain cauliflower very well.

We used a hand beater to whip the cauliflower and garlic like you would potatoes, adding a little milk, Parmesan cheese, and seasoning with salt and fresh ground black pepper. While cauliflower cooks, saute the onion in a little olive oil, then add the poultry seasoning.

I used one cup each of finely diced carrots and frozen peas.  Cook the carrots in the microwave for about 3 minutes to barely soften them. You’ll need about 3 cups diced leftover turkey.  We cut our turkey into chunks about 1 inch square.

I wanted to use turkey gravy to hold the filling together and flavor it, so I looked for the lowest carb gravy I could find and this one that I found at Costco has 3 carbs in 1/4 cup or 21 carbs in the 1 3/4 cups I used in the recipe.  It’s hard to make a diet-friendly recipe that has gravy, but this is definitely not too bad for a dish that makes 8 servings. Add the turkey, partially cooked carrots, peas, and gravy to the pan and simmer a few minutes so the gravy thickens a little more.

Spray an 8″ x 8″ casserole dish with non-stick spray and spread the turkey mixture in the bottom. Then spread the mashed garlic-parmesan cauliflower mixture over that.

Top with grated cheese. Bake uncovered at 375F/190C for about 30 minutes, or until the top is browned and the casserole is bubbly. Serve hot.

Leftover Turkey (or chicken) Shepherd's Pie Casserole with Garlic-Parmesan Cauliflower Topping

This Leftover Turkey Shepherd’s Pie Casserole with Garlic-Parmesan Cauliflower Topping is a great way to use Thanksgiving leftovers, or make it with chicken if you prefer.

Ingredients:

Filling Ingredients

  • 1 onion, chopped in pieces about 1/2 inch
  • 2 tsp. olive oil
  • 2 tsp. poultry seasoning
  • 1 cup raw carrots, diced into 1/4 inch pieces
  • 1 cup frozen peas
  • 3 cups diced leftover turkey or chicken, cut into pieces about 1 inch square
  • 1 3/4 cups turkey gravy (for South Beach Diet, use the gravy with the lowest amount of carbs you can find)
  • 1/2 cup grated cheese blend (I used Four Cheese Blend from Costco)

Topping Ingredients

  • 1 medium-sized head of cauliflower, cut into small pieces
  • 3-4 large cloves garlic
  • 2 T low-fat or skim milk
  • 1/3 cup finely grated Parmesan
  • salt and fresh-ground black pepper to taste

Directions:

  1. Preheat the oven to 375F/190C.
  2. Bring a medium sized pot of salted water to a boil.
  3. Chop cauliflower into small pieces and simmer with the garlic cloves until it’s soft enough to mash easily.
  4. Drain cauliflower very well; then use an immersion blender, food processor, or hand beater to combine the cauliflower with the milk and Parmesan.
  5. Season the mashed cauliflower with salt and fresh ground black pepper to taste.
  6. While the cauliflower cooks, heat the olive oil in a large frying pan and saute the onion 3-4 minutes, then add the Poultry Seasoning (affiliate link) and saute about 1 minute more.
  7. Put the chopped carrots in a glass measuring cup, cover with cling-wrap, and microwave about 3 minutes, or just until barely starting to soften.
  8. Add the partially cooked carrots, diced turkey, peas, and turkey gravy to the pan and simmer on low for 10 minutes, or until the gravy is slightly thickened.
  9. Spray an 8″ x 8″ casserole dish with non-stick spray.  (You need a dish with fairly high sides.)
  10. Spread the turkey-vegetable mixture in the bottom of the dish.
  11. Top with the cauliflower, using a rubber scraper to spread it out so it covers the filling.
  12. Top with the grated cheese.
  13. Bake for 30 minutes, or until the casserole is bubbling and the top is lightly browned.
  14. Serve hot.

Notes:

This freezes well; to reheat, cook in microwave for a few minutes or heat in an oven or toaster oven in a small ovenproof dish covered with foil.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
I used mashed cauliflower in place of potatoes and looked for the lowest-carb variety of turkey gravy I could find to make this a lower-carb dish for the South Beach Diet or other carb-conscious eating plans. Still, even with those changes gravy does contain some flour and the dish has carrots and peas, both of which are high in natural sugar so I’d recommend saving this Leftover Turkey Shepherd’s Pie Casserole with Garlic-Parmesan Cauliflower Topping for a “once-in-a-while-treat” for South Beach phase two. You could skip the peas and carrots and use lower-carb veggies like red peppers and broccoli if you wanted to reduce the carbs.
