Ingredients:
- 3 lbs Sweet Potatoes (Peeled and cubed)
- 4 Tbsp Unsalted Butter (Softened)
- 1/4 cup Whole Milk (Warmed)
- 2 Tbsp Fresh Chives (Finely chopped)
- Salt & Black Pepper (To taste)
- 1 Tbsp Olive Oil
- 1 medium Yellow Onion (Diced finely)
- 2 medium Celery Stalks (Diced finely)
- 3 cloves Garlic (Minced)
- 5 lbs Ground Turkey (93% Lean)
- 1 tsp Dried Thyme
- 1/2 tsp Dried Sage
- 1 Tbsp Dijon Mustard
- 1/2 cup Low Sodium Chicken Broth
- 1 Tbsp All-Purpose Flour
- 1 cup Frozen Peas
- 1/2 cup All-Purpose Flour (For topping)
- 1/2 cup Rolled Oats (Old-Fashioned)
- 1/2 cup Pecans (Roughly chopped)
- 2 Tbsp Brown Sugar (Packed)
- 3 Tbsp Unsalted Butter (Cold, cubed)
- 1/4 tsp Salt (For topping)
Instructions:
- Boil the cubed sweet potatoes in salted water until fork-tender (about 15-20 minutes). Drain the potatoes very well.
- Mash the hot potatoes with the softened butter, warmed milk, chives, salt, and pepper until smooth and creamy. Set aside.
- Preheat the oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
- In a large skillet, heat the olive oil. Sauté onion and celery until softened (about 5 minutes). Add garlic and cook for 1 minute more until fragrant.
- Add the ground turkey to the skillet. Break it up and cook until fully browned. Drain off any excess fat.
- Stir in thyme, sage, Dijon mustard, salt, and pepper. Sprinkle the flour over the mixture and stir for 1 minute. Gradually whisk in the chicken broth until the mixture thickens slightly. Stir in the frozen peas. Taste and adjust seasoning.
- Spread the cooked turkey filling evenly across the bottom of the prepared baking dish.
- Gently spoon the sweet potato mash over the turkey filling, spreading it evenly to the edges.
- Prepare the crumble topping: In a medium bowl, combine flour, oats, chopped pecans, brown sugar, and salt. Cut in the cold, cubed butter using your fingertips or a pastry blender until the mixture resembles coarse breadcrumbs.
- Sprinkle the pecan crumble evenly over the sweet potato layer.
- Bake for 40–45 minutes, or until the filling is bubbling and the topping is deeply golden brown and crisp.
- Let the casserole rest for 10 minutes before scooping and serving.
