Ingredients You’ll Need
This easy 3-ingredient dinner keeps it simple with just potatoes, broth, and a flavorful from-scratch spice mix. If you prep the blend ahead of time, you’ll have a true dump-and-go 3 ingredient slow cooker recipe ready any time.
Potatoes: This is the heart of the soup. I like to use gold potatoes for their creamy texture and mild flavor. Leaving the skins on gives it a rustic, homey feel—and one less prep step for you.
Chicken Broth: Broth adds both flavor and moisture, helping the potatoes cook down and create that silky, comforting base. Feel free to use homemade chicken bone broth if you have it on hand—it’s even better! Just be sure to reserve 1 cup of broth before cooking so you can mix it with the spice blend to thicken the soup at the end.
Homemade Seasoning Blend: This is what sets this soup apart from every other 3 ingredient crock pot recipe. Instead of using canned soup or a store-bought mix with added preservatives, this blend uses pantry spices and cornstarch to add flavor and body. I mix up several jars ahead of time to keep in my pantry.
Optional Toppings: You can keep it simple or dress it up with bacon, cheese, chives, sour cream, or even a splash of cream to turn it into loaded potato soup.
- Chopped crispy bacon
- Shredded cheddar cheese
- Fresh chives
- Dollop of sour cream
- Splash of heavy cream
How to Make 3 Ingredient Potato Soup
Step 1: Dice the potatoes
Dice your potatoes into ½-inch cubes. Add them to the bottom of your Crock Pot or slow cooker.
Step 2: Add the broth
Pour 5 cups of chicken broth over the potatoes. Reserve 1 cup of broth for later.
Step 3: Cook
Cover and cook in your slow cooker (or Crock Pot):
- On LOW for 7.5 hours
- Or HIGH for 3.5 hours
Step 4: Mix the seasoning blend
Whisk the seasoning blend into the reserved 1 cup of broth until smooth.
Step 5: Thicken the soup
Pour the seasoned broth into the bubbling slow cooker. Stir and cook for 30 more minutes, uncovered, until thickened.
Step 6: Blend (Optional)
Use an immersion blender for a smooth, creamy soup or leave it chunky for soft potato bites.
What Makes This Recipe Different
Most potato soup recipes call for a can of condensed soup or a store-bought seasoning packet filled with preservatives, thickeners, and ingredients you can’t pronounce. Not this one. This 3-ingredient crock pot potato soup skips the shortcuts and goes straight for the real stuff.
You’ll use fresh potatoes, real broth, and a homemade seasoning blend that you can mix up in advance. It’s just as convenient as a packet—but better tasting and made with ingredients you actually recognize. This is comfort food the way it should be: simple, wholesome, and from-scratch.

Variations & Add-Ins
There are so many ways to customize this 3-ingredient crock pot potato soup and make it your own:
- Make it vegetarian: Use vegetable broth instead of chicken broth.
- Add protein: Stir in cooked, diced ham toward the end of cooking for a heartier, protein-packed version.
- Corn chowder twist: Add a couple cups of frozen corn during the last hour of cooking to transform it into a cozy corn chowder.
- Extra creamy: Mix in a splash of heavy cream, half and half, or even a bit of cream cheese right before serving.
- Loaded potato style: Top with shredded cheese, crispy bacon, sour cream, or chives—just like a baked potato.
- Try different potatoes: Gold potatoes are my go-to for creaminess, but russet potatoes break down for a thicker, blended texture. Red potatoes hold their shape better if you like it chunky.
Tips for Easy Prep
When I mix up the dry Potato Soup Mix seasoning blend, I like to use half-pint mason jars and prep 2 or 3 batches at a time. That way, the next time I want to make this easy 3 ingredient dinner, all I have to do is dice the potatoes and dump everything into the slow cooker. It’s seriously that simple.
Label the jars and keep them in your pantry for a grab-and-go shortcut that still keeps everything homemade. It’s a little prep now for a no-stress meal later—and what busy homemaker doesn’t need more of those?

FAQs
Yes! Bring the potatoes and 5 cups of broth to a boil in a large pot, then reduce heat and simmer for about 30 minutes or until the potatoes are tender. While the soup simmers, whisk the seasoning blend into the reserved 1 cup of broth until smooth. Pour the mixture into the pot, stir well, and continue simmering for another 5–10 minutes, or until the soup thickens to your liking.
Yes! You can use a 28-ounce bag of frozen diced potatoes (like hash browns) in place of fresh. Just reduce the broth to 3 cups and cut the seasoning blend in half. Frozen potatoes are partially cooked, so they’ll soften faster—check for doneness after about 2.5 hours on HIGH or 6 hours on LOW.
Simply use vegetable broth in place of chicken broth. It’s just as flavorful and makes this soup an easy meatless option.
Definitely. The base recipe is dairy-free—just skip any creamy toppings or stir-ins like cheese, sour cream, or heavy cream.
