How to Make Slow Cooker Irish Potato Soup

Step-by-step guide

Step 1: Prep the vegetables and gather ingredients

I wash and dice 2 pounds of russet potatoes. I finely chop one small onion. I mince two garlic cloves.

I measure 3 cups broth. I measure 1 cup milk. I measure 1 cup cream.

I melt 2 tablespoons butter. I grab thyme, salt, and pepper. Optional: ¼ cup sour cream for extra creaminess.

Step 2: Assemble in the slow cooker and start cooking

I pour the potatoes into the slow cooker. I add minced garlic. I set aside ready to go.

I pour in 3 cups vegetable broth. I drop in butter and thyme. I season with salt and pepper.

Stir to combine and cover. Cook on low for 6 to 7 hours. This Slow Cooker Irish Potato Soup shines with timesaving ease.

Step 3: Tender potatoes and aromatics; adjust cook time if needed

I test tenderness with a fork. Potatoes should be very soft. If not, I extend the time.

For speed, switch to high for 3–4 hours. Check a potato piece with a knife.

Stir once in a while. If you like a chunkier texture, leave some potato pieces unblended.

Step 4: Blend for creaminess or leave chunkier for texture

I blend the soup with an immersion blender. I blend until creamy. For a chunkier texture, blend only half.

Tip: if you don’t own a blender, pulse in batches. Leave some potato pieces unblended for body.

This step helps create the velvety mouthfeel typical of a comforting soup hub.

Step 5: Stir in dairy and finish with cheese

I stir in milk and heavy cream. I add shredded cheddar cheese. I let the cheese melt.

Keep the pot on low heat. Stir until warmed through. Optional: fold in sour cream for extra creaminess.

This step builds the creamy finish you expect in a restaurant-style bowl.

Step 6: Taste, adjust seasoning, and serve with toppings

I taste and adjust salt and pepper. I might add a pinch more salt. I finish with fresh chives; this Slow Cooker Irish Potato Soup is comfort in a bowl.

For serving, ladle into bowls. Garnish with chives and crusty bread.

Relish the cozy aroma and creamy comfort.

Tips for Success

I prep ingredients the night before to save time, always.
I cut potatoes uniformly for even cooking.
I use a liner or spray to prevent sticking.
If you have time, a quick sauté boosts flavor significantly.
Stick to low for depth, high for rush.
I stir gently once, to keep potatoes creamy.
I taste and season at the end; adjust salt.
I top with chives and cheddar just before serving.
I store leftovers airtight and reheat gently for best texture.
