Wash the potatoes and carrots.
Quarter the potatoes.
Quarter the onion, and then slice thickly.
Place the potatoes, carrots and onion in the slow cooker and then toss with the olive oil.
Add the seasonings and stir through.
Add the broth, carefully around the edges; you don’t want to wash the seasonings off of the potatoes.
Cook on low for 4-6 hours, or high for 2-3 hours, stirring halfway through.
Check that the potatoes and carrots are tender and cooked through.
Sprinkle with fresh parsley and serve.
