Ingredients

You only need three basic ingredients:

• 4 large potatoes (Yukon Gold or Russet work best)
• 2 large onions (yellow onions preferred for sweetness)
• 4 cups broth (vegetable or chicken)

Preparation Steps

1. Prep the Vegetables

Start by washing and peeling the potatoes. Cut them into medium-sized chunks so they cook evenly.

Next, peel the onions and slice them thinly. Don’t worry about making perfect slices—just aim for consistent thickness so they cook down nicely.

2. Layer the Ingredients

Place the chopped potatoes into the slow cooker first. Then add the sliced onions on top.

Pour the broth over everything, making sure the vegetables are mostly submerged. This helps them cook evenly and absorb flavor.

3. Set the Slow Cooker

Cover and cook:

• On low for 6–8 hours
  or
• On high for 3–4 hours

As the soup cooks, the onions will soften and become naturally sweet, while the potatoes will break down and thicken the broth.
