Brown ground beef in a skillet with olive oil, diced onions and add garlic last 2 minutes until meat is no longer pink. Dump into slow cooker.
Add peeled and cubed potatoes, carrots, and peas. (or could just use 1 cup mixed frozen vegetables). Pour in the broth, add salt and any seasonings you would like, stir.
Set the High for 2 hours, or low for 4 hours (can leave for total of 6 but veggies will just get softer).
1 hour before serving mix 3 tablespoons of cream with cornstarch or potato starch until smooth, then pour into the pot and stir in with remaining cream and grated cheddar. Cover with a lid, again and cook for the remaining hour to thicken.
