Dice the onion, carrots, and parsnips into small, uniform cubes to ensure even cooking.
Heat the olive oil in a large cast-iron skillet over medium-high heat until shimmering.
Add the ground beef to the skillet, breaking it apart with a spatula until browned and cooked through.
Remove the beef from the pan and set aside, leaving the rendered fat in the skillet.
Add the onion, carrots, and parsnips to the skillet, sautéing for 8-10 minutes until the vegetables are tender and slightly caramelized.
Stir in the minced garlic, sea salt, black pepper, and dried thyme, cooking for 1 minute until fragrant.
Return the beef to the skillet and pour in the beef bone broth and coconut aminos.
Simmer for 3-5 minutes until the liquid has reduced and coated the beef and vegetables in a light glaze.
Serve hot in a shallow bowl for a comforting and nutrient-dense meal.
