FAQs
Can I make this soup without a slow cooker?
Yes, you can prepare this soup on the stovetop. Simmer the vegetables and seasonings in broth over medium heat for about 30-40 minutes until the potatoes are tender, then proceed with mashing and adding cream and butter.
What can I use instead of heavy cream?
Half-and-half or whole milk can be used as lighter alternatives, though the soup will be slightly less creamy. For dairy-free options, try coconut milk or oat milk, but this will alter the flavor slightly.
