One of my favorite slow cooker Kangaroo recipes is this Kangaroo Ragu, easy, delicious, and simple to make using kangaroo steak, sun-dried tomatoes, onions, carrots, and celery. To make Kangaroo Ragu in your slow cooker or crockpot, simply add all ingredients, cover with red wine, and set to cook on low for 6-8 hours or high for 3-4 hours until the meat is tender and flavors meld.
