Preheat your oven to 400°F (200°C) and lightly grease a small baking dish with a touch of oil.
Dice the potato and carrots into uniform 1/2-inch cubes to ensure they cook evenly.
In a large skillet over medium-high heat, add the olive oil and ground turkey, breaking it up with a spatula until browned.
Stir in the diced onion, minced garlic, potatoes, and carrots, cooking for 5 minutes until the onions are translucent.
Season the mixture with dried thyme, rosemary, sea salt, and black pepper, tossing well to coat every piece.
Transfer the turkey and vegetable mixture to the prepared baking dish, spreading it into an even layer.
Bake for 25-30 minutes until the potatoes are fork-tender and the edges are beautifully golden-brown.
