Buttermilk Potato Soup Recipe

This recipe brings out the best in a few simple ingredients. It’s designed for easy preparation and yields a rich, velvety bowl of soup. Whether you’re an experienced cook or a beginner, you’ll find this recipe approachable.

Ingredients Needed

• 5 medium-sized potatoes (russet potatoes work best)
• 1 medium onion (diced)
• 2 tablespoons of butter
• 3 cups of vegetable broth (or chicken broth if preferred)
• 2 cups of buttermilk (full-fat gives the best results)
• 1 cup of milk (whole milk preferred)
• 2 cloves garlic (minced)
• Salt and pepper to taste
• Fresh herbs (optional, but thyme or parsley work well)
• 1 tablespoon of flour (optional, for thickening)
• 1/2 cup of shredded cheddar cheese (optional, for garnish)
• Crumbled bacon bits (optional, for garnish)

Cooking Instructions

1. Prepare the potatoes: Start by peeling and dicing the potatoes into small chunks. This helps them cook evenly and allows the flavors to really soak into the potatoes.
2. Sauté the aromatics: In a large pot, melt the butter over medium heat. Add the diced onion and cook, stirring occasionally, for about 5-7 minutes, until the onion is soft and translucent. Add the garlic and cook for another 1-2 minutes until fragrant. This step builds the flavor base of your soup.
3. Cook the potatoes: Add the diced potatoes to the pot with the onions and garlic. Pour in the vegetable broth and bring to a boil. Once it boils, reduce the heat to low and simmer for about 15-20 minutes, or until the potatoes are fork-tender.
4. Blend (optional): If you like a smoother soup, use an immersion blender to puree the potatoes directly in the pot. Alternatively, transfer half the soup to a blender and puree, then return it to the pot. This will create a creamy texture with some chunks remaining for added heartiness.
5. Add the dairy: Stir in the buttermilk and milk. Bring the soup back to a low simmer. This is where the soup gets its creamy and tangy texture.
6. Season and thicken: Taste your soup and season it with salt and pepper. If you want the soup to be thicker, you can make a quick roux by melting a tablespoon of butter in a separate pan, whisking in a tablespoon of flour, and then adding it to the soup. Stir until the soup thickens.
7. Final touches: Once the soup is the right consistency, remove from heat. Serve it hot, and optionally garnish with shredded cheddar cheese, crumbled bacon, and fresh herbs.

Ingredient Insights

The ingredients in Buttermilk Potato Soup are simple, yet each brings its own distinctive element to the dish. Let’s break down some of the key ingredients and why they work so well together:

• Potatoes: The heart of this soup, potatoes offer a starchy texture that thickens the soup naturally. Russet potatoes are ideal because they break down easily and create a smooth consistency when cooked.
• Buttermilk: The star of the show. Buttermilk adds a pleasant tang that cuts through the richness of the potatoes and butter, creating a balanced flavor profile. It’s also lighter than cream but still brings a creamy texture to the soup.
• Butter: Butter not only adds richness but also enhances the flavors of the onions and garlic when sautéed. It provides a base layer of taste that ties all the other ingredients together.
• Onion & Garlic: These two ingredients are foundational to creating a savory depth of flavor in most soups. They add aromatic richness that works beautifully with the earthy flavor of potatoes.
• Broth: The vegetable broth adds a savory backbone to the soup, providing depth without overwhelming the natural potato flavor. It’s the ideal liquid to create a flavorful base for the soup.

Expert Tips

To elevate your Buttermilk Potato Soup, here are a few expert tips that will take your soup from good to great:

• Use an immersion blender for better control: An immersion blender lets you control the texture of the soup better than a regular blender. Blend to your desired level of smoothness or leave some potato chunks for a heartier soup.
• Fresh herbs: Fresh thyme or rosemary can be added while the soup is simmering. It will infuse the broth with herbal notes and elevate the overall flavor.
• Don’t overcook the potatoes: Keep an eye on your potatoes as they simmer. Overcooking them will cause them to break down too much, which can make your soup overly mushy. Aim for fork-tender potatoes that still hold their shape.
• Go for full-fat buttermilk: For the creamiest texture and the best flavor, opt for full-fat buttermilk. It adds a rich creaminess without being overly heavy, unlike heavy cream.
• Make ahead: This soup actually tastes better the next day as the flavors meld together. So, if you have the time, make it in advance and reheat it slowly.

Recipe Variations

While this buttermilk potato soup recipe is perfect as it is, there are plenty of ways you can tweak it to suit your taste or dietary preferences. Here are a few ideas:

• Vegan version: Swap the butter for olive oil and use a non-dairy milk (such as almond or oat milk) and a vegan alternative for the buttermilk. You can also skip the cheese and bacon for a fully plant-based version.
• Bacon lovers: For an added smoky flavor, cook some bacon until crispy, crumble it, and add it into the soup just before serving. You can also use the bacon drippings to sauté the onions and garlic for extra flavor.
• Spicy kick: For a spicy twist, add a chopped jalapeño or a pinch of cayenne pepper to the soup. The heat will complement the creamy, tangy buttermilk perfectly.
• Cheesy version: Stir in more shredded cheese, like cheddar or Gruyère, into the soup for extra creaminess and flavor. A cheesy buttermilk potato soup is a true indulgence.
• Add vegetables: If you want to boost the nutritional content, consider adding other vegetables like carrots, celery, or spinach to the mix. Simply chop them into small pieces and cook them along with the potatoes.

Final Words

Buttermilk Potato Soup is the kind of dish that transforms a simple meal into something memorable. It’s perfect for any season, but especially satisfying on cold nights when you want a meal that’s both comforting and flavorful. With its balance of creamy and tangy flavors, this soup is guaranteed to become a staple in your recipe rotation. And the best part is, it’s so adaptable.
