Key Ingredients For Your Homemade Leek and Potato Soup
Crafting this delightful soup requires a selection of fresh, high-quality ingredients that, when combined and roasted in the air fryer, create a symphony of flavors. Here’s what you’ll need:
- 3-4 medium potatoes (about 1 pound): The star of the show, providing a creamy texture and hearty base.
- 2-3 large leeks (white and light green parts only): These add a subtle, sweet oniony flavor that is distinct from regular onions, bringing a delicate balance to the potatoes.
- 2 shallots (or approximately 3 ounces): Shallots contribute a milder, more refined onion flavor compared to larger onions, enhancing the complexity of the soup.
- 3 cloves garlic: Essential for aromatic depth and a classic savory undertone.
- 3 Tbsp olive oil: Used for coating the vegetables, allowing them to roast beautifully and develop a rich, golden crust in the air fryer.
- 2 cups chicken or vegetable stock: The liquid base for the soup. Choose vegetable stock for a vegetarian option.
- 1 cup heavy cream: This is what gives the soup its luxurious, creamy texture and decadent richness.
- 1 tsp salt (or to taste): To season and bring out the natural flavors of the vegetables.
- ½ tsp pepper (or to taste): Adds a touch of warmth and enhances the overall seasoning.
- Fresh chives for garnish (optional): A delightful pop of color and a fresh, mild oniony finish.
Special Equipment Note:
Traditionally, potato leek soup is enjoyed for its smooth, creamy consistency. To achieve this desired texture, you’ll want a blender, a sturdy food processor, or a convenient immersion blender readily available. These tools are indispensable for creating that signature silky smooth finish. That said, if you prefer a more rustic, textured soup or simply don’t have these appliances, feel free to skip the blending step and enjoy a delightful chunky soup instead – it’s equally delicious and satisfying!
Ingredient Tips and Smart Substitutions for Your Soup
- For the best creamy texture and subtle sweetness, I typically recommend using Yukon gold potatoes. Their waxy texture holds up well to roasting and blends beautifully. However, you can certainly substitute them with russet potatoes for a starchier, thicker soup, or red potatoes for a slightly firmer, sweeter result if you’re not blending.
- If shallots aren’t available or you prefer a slightly stronger onion flavor, a small white onion can be a suitable substitute. Just make sure to cut it into roughly quarter-inch pieces to ensure even cooking with the other vegetables.
- Olive oil is my go-to for its flavor and cooking properties, but you can definitely use another high smoke point oil such as grapeseed or avocado oil. While butter or margarine can be used for roasting, be mindful that they have a lower smoke point and can burn more easily, potentially affecting the flavor. I tend to avoid them for the initial roasting phase for this reason.
- When selecting your stock, I highly recommend opting for low-sodium or salt-free varieties. This gives you much better control over the final seasoning of your soup, allowing you to adjust salt levels to your personal preference without risking an overly salty dish. Chicken stock adds a wonderful depth of flavor, but vegetable stock works perfectly for a rich, flavorful vegetarian option.
- To adjust the consistency and richness of your soup, consider your liquid choices. For a slightly thinner, lighter soup without sacrificing much creaminess, milk instead of heavy cream can be used. Alternatively, half and half offers a perfect middle-ground, providing a good balance of richness and a slightly lighter texture than full heavy cream.
Step-by-Step: How to Make Air Fryer Potato Leek Soup
Creating this delicious soup is straightforward with the air fryer. Follow these simple steps for a creamy, flavorful result:
- Preheat your air fryer to a steady 400°F (200°C). Ensuring your air fryer is fully preheated is crucial for achieving that desirable crispy, caramelized exterior on your vegetables.
- Prepare the potatoes: Carefully peel your potatoes (this is optional but recommended for a smoother soup) and then cut them into uniform 1-inch cubes. Uniformity ensures even cooking.
- Season the potatoes: In a large mixing bowl, toss the cubed potatoes with 2 tablespoons of olive oil, ensuring each piece is lightly coated. Season generously with salt and pepper to taste.
- Initial potato roast: Transfer the seasoned potatoes into the preheated air fryer basket, spreading them out in a single layer as much as possible for optimal airflow.
- First cook cycle: Cook the potatoes on the air fry setting for 10 minutes at 400°F (200°C). This head start allows the potatoes to begin softening and browning.
- Prepare aromatics: While the potatoes are cooking, prepare your other vegetables. Remove the skin from the garlic cloves and shallots. Halve the shallots and leeks lengthwise, then slice them into approximately ½-inch crescent moon shapes. Remember to thoroughly wash your leeks, getting into all the layers to remove any trapped dirt.
- Season aromatics: In the same bowl used for potatoes, toss the sliced shallots, leeks, and garlic cloves with the remaining 1 tablespoon of olive oil. Season these vegetables with salt and pepper.
- Combine and continue cooking: After the initial 10 minutes, carefully remove the air fryer basket. Add the seasoned shallots, leeks, and garlic cloves to the basket with the par-cooked potatoes. Stir everything together well to ensure an even distribution.
- Final roast: Return the basket to the air fryer and cook for an additional 15-20 minutes at 400°F (200°C). Make sure to stir the vegetables every 5 minutes to promote even browning and tenderization. Continue cooking until the potatoes are fork-tender and the leeks and shallots are beautifully browned and slightly caramelized, signaling a rich depth of flavor.
- Blend the base: Carefully transfer your perfectly roasted vegetables to a blender, food processor, or into a deep bowl if you’re using an immersion blender.
- Achieve creaminess: Blend the vegetables until they are completely smooth and free of any large lumps. Then, gradually add the heavy cream and chicken or vegetable stock. Blend again until all liquids are thoroughly incorporated, resulting in a wonderfully smooth and creamy soup.
- Garnish and serve: Pour your hot, creamy potato leek soup into serving bowls. For an extra touch of freshness and flavor, garnish generously with chopped fresh chives. Serve immediately and enjoy!

Frequently Asked Questions About Air Fryer Potato Leek Soup
Can You Cook Potato Soup Directly in the Air Fryer?
While you cannot cook liquid soup directly in the air fryer basket, you absolutely can use the air fryer to perfectly cook and roast all the essential vegetables that form the delicious base of your potato soup. This method caramelizes the vegetables beautifully, adding immense depth of flavor. Once your vegetables are roasted, you then transfer them to a blender or pot to combine with liquids and finish the soup. Additionally, for convenience, you can easily heat up pre-made, canned, or leftover potato soup in the air fryer. Simply pour the soup into an oven-safe bowl, cover it with foil to prevent any splattering, and air fry it for about 10 minutes at 375°F (190°C). Cooking times may vary depending on the size and material of your bowl, so keep an eye on it.
Is It Necessary to Peel Potatoes for Potato Soup?
If your intention is to achieve a luxuriously smooth, creamy potato soup through blending, then it is highly recommended to peel the potatoes. Leaving the skins on can result in small, undesirable fibrous bits in the final blended texture. However, if you prefer a rustic, chunky soup where the potatoes remain in distinct pieces, then peeling is entirely optional and comes down to personal preference. In a classic dish like potato leek soup, which is traditionally known for its silky consistency, peeling the potatoes is customary to ensure that signature smooth mouthfeel.
What is the Best Thickener for Potato Soup?
The most natural and effective thickener for potato soup is actually the potatoes themselves! Potatoes are naturally rich in starches that, when cooked and blended, release and contribute significantly to thickening the soup. When these starches are combined with a healthy fat, such as butter or heavy cream, they create an incredibly rich, thick, and velvety consistency without the need for additional flour or cornstarch. If, however, you find your soup still needs a little extra body after blending, a simple cornstarch slurry (cornstarch mixed with a small amount of cold water) is an excellent and virtually flavorless next best option to achieve your desired thickness.
Does Roasting Vegetables In An Air Fryer Improve The Flavor Of The Soup?
Absolutely! Roasting vegetables like potatoes and leeks in an air fryer significantly elevates the flavor profile of the soup. The dry, circulating heat of the air fryer promotes the Maillard reaction, which caramelizes the natural sugars present in the vegetables. This process develops a deeper, richer, and more complex taste compared to simply boiling or steaming them. The resulting slight char and intense browning contribute an irresistible savory depth that truly sets this air fryer soup apart. It delivers a similar profound flavor to traditional oven roasting but achieves it in a significantly shorter amount of time and with less energy consumption.
What Are The Benefits Of Using An Air Fryer For Potato Leek Soup?
Utilizing an air fryer for potato leek soup offers several distinct advantages that make the cooking process more efficient and the end product more flavorful. Firstly, it considerably speeds up the vegetable cooking and roasting process compared to a conventional oven, making it ideal for weeknight meals. Secondly, the air fryer requires less oil than traditional deep-frying or pan-roasting, contributing to a healthier dish. Most importantly, it imparts a rich, roasted, and slightly smoky flavor to the potatoes and leeks that significantly enhances the soup’s overall depth. Furthermore, the air fryer is wonderfully convenient, demanding less constant attention compared to active cooking on a stovetop, allowing you to multitask or relax while your vegetables roast to perfection.
Can You Make A Creamy Potato Leek Soup With An Air Fryer?
Yes, absolutely! The air fryer is an excellent tool for preparing the foundation of a wonderfully creamy potato leek soup. After expertly roasting the potatoes and leeks in the air fryer to achieve optimal tenderness and flavor, you’ll then transfer these caramelized vegetables to a blender. There, you’ll combine them with rich broth and heavy cream, blending until you achieve a luxuriously smooth and velvety consistency. Depending on your preferred serving temperature, you may wish to gently reheat your blended soup after adding the liquids. This can be done quickly in the microwave for a rapid warm-up, or slowly on the stovetop for a more controlled heat.
Recipe Pro Tips For the Best Air Fryer Leek and Potato Soup
To ensure your air fryer potato leek soup turns out perfectly creamy, flavorful, and hassle-free every time, keep these expert tips in mind:
- Thoroughly Clean Your Leeks: Leeks are notorious for trapping dirt and grit between their layers. If you’re not accustomed to cooking with leeks, take extra care to wash them thoroughly. Slice them open lengthwise, then rinse them under cold running water, fanning out the layers to ensure all dirt is removed before chopping. This prevents any unwanted grittiness in your smooth soup.
- Adjust Temperature After Blending: After blending your roasted vegetables with the cool cream and stock, the soup’s temperature might drop. If you prefer a piping hot bowl, simply reheat your soup for a minute or two in the microwave. Alternatively, you can return it to the air fryer in an oven-safe bowl, covered with foil to prevent splashes, and heat for 5-6 minutes at 400°F (200°C) until warmed through.
- Customize the Consistency: This recipe yields a delightfully thick and creamy soup, perfect for cold days. If you prefer a thinner consistency, simply add more chicken or vegetable stock, or even a splash of milk, until it reaches your desired soupiness. Adjust gradually and taste as you go.
- Air Fryer Models Vary: My personal Ninja Dual Zone air fryer yielded perfectly cooked vegetables at the 15-minute mark during the second cooking phase. However, air fryer models can differ in their heating efficiency. Always use the suggested cooking times as a guideline and check for doneness (fork-tender potatoes, browned leeks) to adjust cooking duration as needed for your specific appliance.
Storage and Reheating Your Delicious Potato Leek Soup
One of the best things about homemade soup is enjoying the leftovers! Here’s how to store and reheat your air fryer potato leek soup to maintain its deliciousness:
- Storage: Any leftover creamy potato leek soup should be stored in an airtight container and kept refrigerated. It will maintain its quality and flavor for approximately 3-4 days, making it perfect for meal prepping easy lunches throughout the week.
- Reheating: For reheating, I actually find the microwave to be the most efficient and recommended method. Heat individual portions for about 1 minute on high, or adjust the time based on your portion size and microwave wattage until it’s warmed through. While you can also heat it on the stovetop over medium heat, this takes longer (though it’s a perfectly good option if you don’t have a microwave). The air fryer, unfortunately, isn’t ideal for reheating liquids or semi-liquids, as it can take 15-20 minutes to heat thoroughly, potentially drying out the soup or not heating evenly. It’s generally not worth the effort unless you genuinely have no other options available.

Notes
- I usually use Yukon gold potatoes for this, but you can sub in russet or red potatoes as well.
- The shallots may be substituted by a small white onion (use quarters instead of halves) if preferred.
- Instead of olive oil, you can sub another high smoke point oil (grapeseed, avocado, etc). Butter or margarine can work, but they burn easier so I tend to avoid them.
- Use low sodium or salt free stock so that you can better control the amount in the soup. Chicken adds nice flavor, but vegetable stock is great if you’re keeping this vegetarian.
- For a thinner soup, use milk instead of heavy cream. Alternatively, half and half may be used here as well.
- Leeks are naturally very dirty. Make sure to wash your leeks thoroughly, including between layers to remove dirt.
- When adding the liquids, it may cool the soup down too much. Reheat your soup for a minute or two in the microwave, if needed. Alternatively, you can heat it in the air fryer in an oven-safe bowl covered in foil for 5-6 minutes at 400°F (200°C).
- This recipe makes a nice, thick, creamy soup. If you want it thinner, add some additional stock or milk to make it soupier.
