Can You Vary The Recipe With Other Ingredients? 

  • Keto: Replace regular potatoes with a lower-carb option like cauliflower or turnips. Use grass-fed butter instead of margarine and heavy cream for richness.
  • Paleo: Again, substitute regular potatoes with sweet potatoes. Use ghee instead of margarine, almond milk, or coconut milk instead of heavy cream.
  • Gluten-Free: The basic recipe is already gluten-free; ensure that any broth used is certified gluten-free.
  • Whole30: Substitute margarine with ghee and skip the heavy cream; you might add some coconut cream instead.
  • Vegetarian: The basic recipe is already vegetarian. However, you could add some extra vegetables or pulses for more variety and nutrition.

Can I Make Potato and Onion Soup In A Slow Cooker Or Instant Pot?

Slow Cooker

  • Add the butter, onions, leeks, potatoes, water, and salt to the slow cooker.
  • Cover and cook on low for 6-8 hours or on high for 3-4 hours until the potatoes are very tender.
  • Use an immersion blender to blend the soup until smooth, or carefully blend in batches in a regular blender.
  • Stir in additional butter, cream, and chives, and heat for another 15-20 minutes. Make sure the soup does not boil to prevent the cream from curdling.

Instant Pot

  • Use the sauté function to melt the butter and wilt the onions.
  • Add the leeks, potatoes, water, and salt. Seal the Instant Pot and set it to pressure cook on high for 15 minutes.
  • Allow a natural pressure release for 10 minutes, then manually release the rest of the pressure.
  • Blend the soup until smooth, then use the sauté function to heat the soup with the additional butter, cream, and chives. Again, make sure the soup does not boil.

Can I Use Store Broth, Or Should I Make My Own?

  • Store-bought Broth: This is a great option for convenience and time-saving. When buying, opt for low-sodium versions so you can control the salt level of your soup. Also, look for high-quality, organic broths that don’t contain preservatives or additives.
  • Homemade Broth: If you have the time and ingredients, homemade broth can bring a depth of flavor that is hard to match. You can make it from vegetable scraps or bones and leftover meat from a roast. It’s economical and allows for complete control over the ingredients and flavor profile.

How To Serve ?

  • Warm Bread: Serve it hot alongside a slice of crusty Bread, a roll, or even a grilled cheese sandwich. The Bread makes for a hearty addition, especially during cold days, and it’s perfect for dipping!
  • Garnish: Dress up your soup with a sprinkle of fresh chives, a swirl of cream, or a drizzle of good-quality olive oil just before serving. You could also add a few croutons for some crunch.
  • Serve in a Bread Bowl: If you feel fancy and fun, you could serve your soup in a bread bowl. Simply hollow out a round loaf of Bread, pour in your soup, and you have a meal and serving dish in one!
  • Pair with a Salad: For a more balanced meal, serve the soup with a fresh, crisp salad. A simple green salad with a vinaigrette dressing can provide a refreshing contrast to the rich and creamy soup.
  • Wine Pairing: If you enjoy wine with your meal, a white wine like a Chardonnay or Sauvignon Blanc would go well with this soup.

Perfect Side Dishes

  • Crusty Bread: A slice of warm, crusty Bread, perhaps lightly buttered or toasted, is a classic side to any soup. It’s perfect for dipping and soaking up the delicious soup.
  • Green Salad: A light and crisp green salad with a tangy vinaigrette can provide a refreshing contrast to the creamy soup. It could include mixed greens, cherry tomatoes, cucumber, and perhaps some crumbled feta or goat cheese.
  • Grilled Cheese Sandwich: A comforting grilled cheese sandwich pairs wonderfully with soup, and its crunchiness would be a nice texture contrast to the smooth soup.
  • Roasted Vegetables: To complement the soup, roasted veggies like Brussels sprouts, carrots, or parsnips can add additional nutrition and flavors.
  • Quiche or Tart: A small slice of a savory quiche or tart can make the meal more substantial. Consider a simple cheese and onion quiche or a spinach and feta tart.
  • Charcuterie Board: If you’re serving the soup as a starter for a dinner party, consider pairing it with a charcuterie board filled with a selection of cheeses, cured meats, olives, and fruits.

Storage And Make Ahead

  • Storage: Store leftover soup in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop or in the microwave until heated through.
  • Freezing: This soup freezes well. Allow it to cool completely before transferring it to a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
  • Make Ahead: You can make this soup ahead of time and store it in the refrigerator for up to 2 days before serving. This is perfect for planning meals in advance or for busy weeknights. Just reheat gently before serving.

What Can We Do With Leftovers?

  • Reheat and Eat: Reheat the leftover soup on the stove or in the microwave for a quick and comforting meal.
  • Add to Casseroles: Blend the soup until smooth and use it as a base for casseroles, adding a creamy richness.
  • Create a Sauce: Reduce the leftover soup on the stove until it thickens and use it as a savory sauce for grilled meats or roasted vegetables.
  • Mix with Grains: Stir the soup into cooked rice, quinoa, or barley for a tasty, moist side dish.
  • Freeze for Later: Portion the leftovers into freezer-safe containers and freeze them for a future meal.
  • Make a Dip: Thicken the soup with some mashed potatoes or cream cheese, and it becomes a delightful dip for Bread or crackers.
  • Turn into a Chowder: Add corn, bacon, or other ingredients to turn the leftover soup into a new chowder version.
  • Use in Bread Making: Replace some of the liquid in bread recipes with soup for a flavorful twist in your homemade loaves.


  • To save time, chop potatoes and onions into small, uniform pieces.
  • For extra flavor, sauté onions until caramelized before adding potatoes and broth.
  • Add a pinch of smoked paprika for a rich, smoky taste.
  • Blend half of the soup for a creamy texture while leaving the other half chunky.
  • Garnish with fresh herbs like parsley or chives for a burst of freshness.
