Ingredients:
- 4 large Sweet Potatoes (about 3 lbs), peeled and chopped
- 2 Tbsp Unsalted Butter
- ½ cup Milk or Heavy Cream (Warmed)
- Salt and Black Pepper, To taste
- ¼ tsp Nutmeg (optional)
- 1 Tbsp Olive Oil
- 1 large Yellow Onion, finely diced
- 2 medium Carrots, finely diced
- 2 stalks Celery, finely diced
- 4 cloves Garlic, minced
- 5 lbs Ground Turkey (93% lean)
- 2 Tbsp Tomato Paste
- 1 tsp Dried Thyme
- ½ tsp Dried Rosemary (optional)
- 1 tsp Smoked Paprika
- 1 Tbsp All-Purpose Flour (or cornstarch)
- 5 cups Chicken or Vegetable Stock (low sodium)
- 1 cup Frozen Peas
- 1 tsp Worcestershire Sauce
- Kosher Salt and Freshly Ground Black Pepper, To taste
Instructions:
- Place peeled and roughly chopped sweet potatoes in a large saucepan. Cover with cold water and add a generous pinch of salt. Bring to a boil, then reduce heat and simmer until fork-tender (about 15-20 minutes).
- Drain the potatoes thoroughly. Return them to the hot pan to steam for 1 minute to remove excess moisture—this is crucial for a non-soggy topping.
- Add butter, warm milk/cream, and seasonings (salt, pepper, optional nutmeg). Mash until smooth and creamy. Taste and adjust seasoning and set aside.
- Preheat a large skillet or Dutch oven over medium-high heat with olive oil. Add the diced onion, carrots, and celery. Cook for 5-7 minutes, until the vegetables are softened and the onions are translucent.
- Add the ground turkey to the skillet. Break it up with a wooden spoon. Cook until the turkey is browned and no pink remains. Drain any excess fat, if necessary.
- Stir in the minced garlic, tomato paste, thyme, rosemary, and smoked paprika. Cook for 1 minute, stirring constantly, until the paste deepens in colour.
- Sprinkle the flour (or cornstarch) over the turkey mixture and stir well for 1 minute to coat everything. This helps thicken the sauce.
- Pour in the chicken stock and Worcestershire sauce. Bring the mixture to a simmer, scraping up any browned bits. Reduce the heat and let it simmer gently for 5-8 minutes, or until the sauce has thickened nicely.
- Stir in the frozen peas. Season aggressively with salt and pepper. The filling should taste vibrant and flavourful.
- Preheat the oven to 375°F (190°C). Transfer the hot turkey filling into a 9x13 inch casserole dish, spreading it in an even layer.
- Carefully spoon the sweet potato mash over the turkey layer. Spread it gently to cover the filling completely. Use a fork to create ridges on the surface.
- Bake for 25-30 minutes, or until the filling is bubbling at the edges and the sweet potato topping is lightly golden brown and heated through.
- Allow the casserole to rest for 5 minutes before serving. This allows the filling to settle, preventing a runny mess when portioned.
