Ingredients for Dairy Free Mashed Potatoes

Cannellini beans, potatoes, shallots, broth, and herbs for slow cooker dairy free mashed potatoes

Of course, this recipe contains some staple mashed potato ingredients such as potatoes, seasonings, broth, and spices and is made vegan with a simple swap of dairy-free milk. However, what makes them truly unique is the inclusion of the white bean sage puree made with Cannellini beans!


Foodie Swap: White Northern beans can be used in place of Cannellini beans to achieve the same buttery taste!

Nutrition Tip: Did you know that white beans are considered to be pulses along with dried peas, lentils, and chickpeas meaning they’re high in fiber, protein, plant-based iron, and folate! 

White Bean Sage Puree Ingredients & Benefits

Made of Cannellini beans, olive oil, vegetable broth, sage leaves, minced garlic, salt, and pepper, the bean puree is my secret weapon to create the creamiest dairy free mashed potatoes ever! Once blended, the puree can be used to replace butter in not only this recipe but any baked good such as cookies or bread, too! 

Plus, it can be used to promote better gut health! The combination of white beans and potatoes that has been cooked and cooled is a great source of resistant starch or prebiotic fiber that helps feed the good bacteria in your gut. This means that this dish can help improve your gut flora which in turn improves your digestion and immune system

  1. Wash and Peel. Definitely make sure to remove any dirt particles from your potatoes by washing them. Then, peel the skin off before cooking to eliminate the chance of any chunks.

2. Mash Well. Make sure to mash and blend the potatoes until smooth using a food processor, hand blender, blender, or immersion blender. 

Pro Tip

Pro-Tip: For extra creamy mashed potatoes, use a blender to combine the potatoes and white bean puree into a smooth consistency. 

3. Thin Out. If your mashed potatoes are too thick, thin them out a bit by adding 2-4 tablespoons more of broth or dairy milk.

Preparation and Storage

For the best texture and flavor, I recommend serving this vegan mashed potatoes recipe right away! However, if you do have leftovers, store them covered in the fridge for 2-3 days

Pro Tip

Note: If your potatoes thicken in the fridge, stir in another dash of dairy free milk or broth, and heat them up in the microwave or oven! 

Common Questions

What are the best potatoes to use?

For the best results, I recommend using golden or yellow potatoes! They have a slightly creamier taste and texture when compared to other potato varieties such as white Russet potatoes, red, or sweet potatoes.

Can I leave the skin on the potatoes?

Yes, the skin will add a bit more texture to this dish, but it’s a great way to add even more fiber!

What can I substitute for dairy free milk?

An easy substitute for both regular dairy and dairy free milk is extra broth! Just keep in mind that the flavor of your mashed potatoes will be slightly altered.

Can I use water instead of dairy free milk?

Due to the fact that milk is used to add flavor and help create a creamy texture, I do not recommend using water to replace it in thes dairy free mashed potatoes.

  • For thinner or extra creamy mashed potatoes, add extra non milk or non dairy cream as needed.
  • If you don’t have an immersion blender, you can continue to mash the beans and potatoes with a masher. Or, place the cooked mashed potatoes in a blender. If using a blender, add liquid, broth or non dairy milk (2-4 Tablespoons), and blend the ingredients until creamy.
