Ingredients:
- 2 kg (2.6 lbs) Sweet Potatoes, peeled and cubed
- 60 ml (1/4 cup) Whole Milk or Cream
- 30 g (2 tbsp) Unsalted Butter or Olive Oil
- 1 tbsp Olive Oil (extra virgin)
- 1 medium Yellow Onion, diced finely
- 1 large Carrot, peeled and diced finely
- 1 Celery Stick, diced finely
- 2 cloves Garlic, minced
- 700 g (1.5 lbs) Lean Ground Turkey (93% lean suggested)
- 2 tbsp All-Purpose Flour or 1 tbsp Cornstarch
- 1 tbsp Tomato Paste (concentrated purée)
- 1 tsp Dried Thyme
- 1/2 tsp Dried Sage
- 500 ml (2 cups) Chicken Stock (low sodium)
- 1 tbsp Worcestershire Sauce (optional)
- Salt and Pepper to taste
- 100 g (3.5 oz) Frozen Peas
- 50 g (1/2 cup) Grated Cheddar Cheese (optional)
- A dusting of Smoked Paprika
Instructions:
- Place the cubed sweet potatoes in a large pot, cover with cold, salted water, and bring to a boil. Cook until fork-tender (about 15-20 minutes).
- Drain the potatoes thoroughly. Return them to the hot pot. Add butter, milk, salt, and pepper. Mash until smooth and creamy. Set aside.
- Heat olive oil in a large skillet over medium heat. Add the diced onion, carrot, and celery. Cook gently for 8–10 minutes until softened. Add the minced garlic and cook for 1 minute until fragrant.
- Push the vegetables to one side. Add the ground turkey to the pan and break it up with a spoon. Cook until the turkey is fully browned. Drain off any excessive rendered fat.
- Stir in the tomato paste, dried thyme, and sage. Cook for 1 minute. Sprinkle the flour (or cornstarch) over the mixture and stir well for 30 seconds to coat everything.
- Pour in the chicken stock and Worcestershire sauce. Bring to a simmer, then reduce heat and gently bubble for 5–7 minutes until the sauce thickens and the flavours meld. Season generously with salt and pepper.
- Stir in the frozen peas. Remove the skillet from the heat.
- Preheat the oven to 200°C (400°F). Lightly grease a 9x13 inch casserole dish. Pour the turkey mixture evenly into the bottom of the dish.
- Carefully spoon the sweet potato mash over the filling. Spread evenly, sealing the edges. Create peaks or texture marks on the surface with a fork.
- Optional Finish: Sprinkle the grated cheddar cheese (if using) and a light dusting of smoked paprika over the topping.
- Bake for 25–30 minutes, or until the filling is bubbling hot around the edges and the sweet potato topping is golden brown and slightly crisp on top.
- Allow the casserole to rest for 5–10 minutes before serving.
