Life can get so busy sometimes, and making a quick homemade dinner can be a challenge. That’s when I enjoy making this 3 ingredient easy potato soup, it’s simple and satisfying. It’s amazing how a few basic ingredients with proper cooking techniques can come together to create something so warm and comforting to enjoy for dinner.

Especially on a hectic weeknight or when I’m trying to make the most of what I have in my kitchen without having to run to the store.

Ingredients You Will Need

It can’t get any easier; only 3 simple ingredients are needed to create this flavorful potato soup.

Bowls on a marble surface contain ingredients for cooking: a pot with vegetable stock, a square dish with chopped onions, and a round bowl with diced white potatoes. Each is labeled accordingly.
  • Oil or Butter: Unsalted butter or high-quality olive oil – for better flavor and seasoning control.
  • White Potatoes: Yukon Gold or Russet – firm, smooth, and free of green spots or sprouts.
  • Onion: Yellow onion – with dry skin and no soft or moldy spots.
  • Vegetable Stock: I use store-bought boxed vegetable broth.
  • Salt and Pepper: To taste

Variations and Substitutions

Extra Creamy: Alternatively, making it a 4 ingredient soup by adding a splash of heavy cream at the end of your cooking time results in added richness.

Make Homemade Veggie Broth With Srcaps: A homemade vegetable stock adds depth without added cost. By simmering onions and vegetable scraps in water for a few hours. Sometimes I toss all the veggie scraps in my crock pot, add water and set it on low in the morning. I create a vibrant stock that keeps well in the freezer.

Stock Options: It can be a delightful alternative for those who prefer chicken stock. I also have used boxed chicken bone broth as a nutritious alternative.

Make Creamy Potato Soup: If a creamy texture is desired, blending the soup partially or completely with a stick blender can achieve this.

How To Make Easy Potato Soup

Heat 1 tablespoon of butter in a large soup pot over medium heat. Add the diced potatoes and onion. Cook for about 10 minutes, stirring occasionally, until softened.

Gina’s Tips For Recipe Sucess

  • Sautee Veggies: When making this simple potato soup, I start by sautĂ©ing the onions and potatoes in a touch of oil. This process draws out their flavors and reduces cooking time.
  • Cutting Uniform Potato Cubes: Dicing potatoes evenly ensures they cook at the same rate. Use a sharp knife and a stable cutting board for precision.
  • Taste as You Season: Add salt gradually and taste as you go to avoid over-salting, especially if using salted stock.
  • Optional Garnishes: For extra flavor and texture, garnish with a drizzle of olive oil, croutons, or grated cheese like Parmesan.
