A Taste of Scotland

I grew up on this recipe and can’t get enough of it when it’s chilly outside or I’m feeling a bit under the weather.
🗝️ Key Ingredients & Substitutions
The star of the show, red lentils, cook quickly and bring a lovely, earthy flavor and creamy texture to the soup. They’re a fantastic source of protein and fiber. If you don’t have red lentils on hand, you can substitute them with French green lentils or brown lentils, though the cooking time might vary slightly.
Ham or Vegetable Stock
The base of any good soup, the stock enriches the soup with depth and savoriness. Using ham stock will add a smoky, meaty flavor, while low sodium vegetable broth keeps things plant-based. Chicken broth is a great substitute if needed. Water can also be used in a pinch, though you might want to up the seasonings to compensate for the reduced flavor.
Leftover Ham Bone or Ham Stock Cubes
If you’ve got a leftover ham bone, this soup is the perfect place to use it. It infuses the broth with a rich, meaty essence. No ham bone? Ham stock cubes paired with diced ham or bacon will work wonderfully too. For a vegetarian version, simply omit this and perhaps add a bay leaf for an extra layer of flavor.
Vegetables: Carrots, Turnip/Rutabaga, Onions, and Potatoes
This medley of vegetables adds not only nutrition but also texture and sweetness to the soup. Each one plays its role, from the earthiness of the turnip to the natural sugars of the carrots and onions. Note: Rutabaga is called turnip in Scotland. Not a fan of turnips? Try swapping in half a white cabbage or even some diced butternut squash for a different twist.
Seasonings: Salt and Ground Black Pepper
Simple seasonings let the natural flavors of the ingredients shine through. Salt and pepper can be adjusted to taste, and this is also where you can get creative. A pinch of curry powder, a dash of ground cumin, or even a sprinkle of nutritional yeast can add an extra dimension to your hearty soup.
🥣 How to Make Instant Pot Lentil Soup
Creating this heartwarming bowl of lentil soup in your Instant Pot or electric pressure cooker is a breeze. Follow these straightforward steps, and you’ll have a delectable meal ready in no time.
Assembling in the Instant Pot
Begin by gathering all your ingredients. Chop your vegetables into bite-sized pieces to ensure they cook evenly.
Place the red lentils, chopped vegetables, ham bone and/or ham scraps (or ham stock cubes and diced ham or bacon), and seasonings into the Instant Pot pressure cooker. Pour in your chosen stock—ham or vegetable—ensuring that the ingredients are well submerged. This will be the foundation of your soup’s flavorful broth.
Secure the lid of your Instant Pot and turn the valve to the “sealing” position. Select the ‘pressure cook’ or ‘manual’ setting, then press ‘high pressure’ and set the timer for 10 minutes. The Instant Pot will take a few moments to build up pressure before the cooking time begins. During this time, the ingredients will start to meld together, creating a rich and savory soup base.
Once the cooking time is up, allow the Instant Pot to naturally release pressure for 30 minutes. This gradual release is crucial as it allows flavors to continue to develop. After 30 minutes, carefully turn the valve to “venting” to quick release any remaining pressure.
Blending and Seasoning
Remove the ham bone from the pot, as well as any large chunks of meat. Using an immersion blender, blend the soup to your desired consistency. If you don’t have an immersion blender, you can transfer the soup in batches to a blender or food processor.
Once blended, chop any large meat pieces from the ham bone and stir them back into the soup.
Give it a taste and adjust the seasoning as needed. Your Instant Pot Lentil Soup is now ready to serve!
🪄 Recipe Notes & Tips
The Importance of Natural Pressure Release
One of the key steps in this instant pot recipe is allowing the Instant Pot to naturally release pressure. This might seem like a small detail, but it’s crucial for a couple of reasons. First, it prevents the soup from spurting out of the valve—a messy and potentially dangerous situation. Second, it allows the soup to continue cooking gently, ensuring that every ingredient melds together perfectly.
Achieving the Perfect Consistency
The beauty of this soup is that it can be as chunky or as smooth as you like. If you prefer a chunkier soup, simply blend a portion of it, leaving some of the vegetables and lentils intact for texture. For a creamier soup, blend it thoroughly. Remember, the longer you blend, the smoother your soup will be.
This recipe is wonderfully adaptable to different taste preferences. Feel free to play around with the seasonings. Add a bay leaf for a subtle depth of flavor, or throw in a dash of smoked paprika for a smoky twist. If you like a bit of acidity in your soup, a squeeze of lemon juice can brighten up the flavors beautifully.
The Role of Lentils
Lentils are a fantastic ingredient as they don’t require pre-soaking and cook relatively quickly. Red lentils, in particular, break down and thicken the soup, giving it a creamy consistency without the need for dairy. If you substitute them for green or brown lentils, which hold their shape better, expect a soup with more texture.
Storage Instructions For Leftover Soup
Instant Pot Lentil Soup not only makes a satisfying meal but also stores beautifully, making it perfect for meal prep or enjoying leftovers throughout the week.
Cooling and Storing
Before storing, allow the soup to cool down to room temperature. Transfer the cooled soup to an airtight container. Airtight containers are key in preserving the soup’s freshness and preventing any unwanted fridge odors from seeping in.
Your delicious lentil soup can be stored in the refrigerator for up to 5 days. The flavors often meld and deepen over time, making the leftovers taste even better! When you’re ready to enjoy it again, simply reheat the soup on the stovetop over medium heat or in the microwave.
Freezing for Longevity
For longer storage, freezing is a great option. This easy lentil soup recipe freezes exceptionally well. Portion the soup into freezer-safe containers or freezer bags, leaving some space at the top as the soup will expand when frozen. Properly stored, it can last in the freezer for up to 3 months. Thaw overnight in the refrigerator or use the defrost setting on your microwave when you’re ready to enjoy it.
When reheating, you may notice the soup has thickened. This is completely normal as the lentils continue to absorb liquid. Simply add a bit of water or broth to reach your desired consistency. Warm the soup over medium heat on the stove, stirring occasionally, or use your microwave, stirring every couple of minutes to ensure even heating.
🍽️ What Can I Serve With Lentil Soup?
There’s nothing like a slice of warm, crusty bread to dip into a velvety soup. Whether it’s a gluten-free baguette, sourdough, or a hearty whole-grain loaf, bread is a timeless companion to any soup. And if you’re feeling fancy, spread a bit of garlic butter on your slice and toast it for an extra layer of flavor.
A sprinkle of chopped fresh parsley or fresh thyme can make a world of difference. Not only do these herbs add a burst of color to your bowl, but they also bring in a fresh aroma and taste that contrasts beautifully with the rich depth of the soup.
Dairy and Dairy-Free Toppings
A dollop of yogurt, a drizzle of coconut milk, or a sprinkle of nutritional yeast can add a delightful creaminess to your soup. And for those who enjoy cheese, a few shavings of Parmesan cheese can be absolutely divine.
Salads and Greens
If you’re looking for something light to balance out the meal, a simple green salad with a lemon vinaigrette is a fantastic choice. Alternatively, stir in some baby spinach with a drizzle of olive oil to the soup just before serving. The heat from the soup will wilt the spinach just enough, adding a delightful texture and a boost of nutrients.
For those who like a little kick, red pepper flakes or a dash of curry powder can elevate your bowl to new spicy heights. Remember, it’s all about crafting the perfect bite that suits your taste buds.
