Begin by heating the olive oil in a skillet over medium heat. Add the chopped onions and sauté until soft and translucent, about 5 minutes. This step enhances their natural sweetness and depth but can be skipped if you’re short on time. Meanwhile, peel (if desired) and dice the potatoes into bite-sized pieces.
In a large mixing bowl, combine the ground turkey, eggs, panko bread crumbs, half of the salt, pepper, ketchup, and the sautéed onions. Mix everything gently until just combined—overmixing can make the meatloaf dense.
Lightly grease the bottom of your crock pot. Spread the diced potatoes and baby carrots evenly across the base. Sprinkle the remaining salt over the veggies for seasoning. Shape the turkey mixture into a loaf that fits comfortably on top of the vegetables, pressing gently to shape.
Spread an additional layer of ketchup over the top of the meatloaf for that classic tangy glaze. Cover and cook on low for 6-8 hours, or on high for 3-4 hours, until the meatloaf is cooked through and the vegetables are tender.
Once cooked, carefully remove the meatloaf from the crock pot. Use a slotted spatula to lift portions of the vegetables alongside each meatloaf slice. Enjoy the delicious, juicy meat paired with perfectly cooked veggies.
