Rinse the split peas under cold water and pick out any debris.
Add the rinsed peas, sliced carrots, diced onion, minced garlic, diced potatoes, vegetable broth, bay leaf, and dried thyme to the slow cooker.
Stir the ingredients to combine them evenly.
Cover and cook on low for 7 to 8 hours until the split peas are soft and the vegetables are tender.
Remove the bay leaf. Season with salt and black pepper to taste, then stir well before serving.
