Soups & Stews
This Ninja Foodi potato soup delivers restaurant-quality velouté with crispy celery crowns—all in one pot. The secret lies in using your pressure cooker’s sauté function to develop deep, caramelized flavors before sealing the lid, creating a creamy base that’s rich without being heavy.
What sets this apart is the air-fryer finish: after pressure cooking, the celery tops crisp to golden perfection while the soup remains silky-smooth below. The beauty of this method is efficiency: 30 minutes total, with minimal prep.
You’ll start by sautéing onions and garlic until fragrant, then add potatoes, broth, and herbs before sealing the lid. The pressure cooker does the heavy lifting, infusing flavors while keeping the potatoes perfectly tender. No need for separate pots or blenders—just one seamless process.
What you’ll end up with is a creamy herb-infused soup topped with crispy celery crowns that add texture and visual appeal. The velouté is velvety without being greasy, thanks to a touch of cream and a pinch of nutmeg for warmth.
This is the kind of soup that feels indulgent yet balanced—ideal for chilly evenings or hearty lunches. The Ninja Foodi’s dual functions make this recipe foolproof. Whether you’re using the pressure cook setting for speed or the air-fryer for crispy tops, the results are consistently professional.
Serve with crusty bread to soak up every last drop of that creamy goodness.
Ingredients for potato soup recipe ninja foodi
Pantry staples and fresh herbs—this Ninja Foodi magic creates velvety soup with crispy celery crowns.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Onions 🧅 | 1 whole | Diced into small pieces |
| Garlic Cloves 🧄 | 4 cloves | Minced for fragrant base |
| Russet Potatoes 🥔 | 2 lb | Peeled, cut into 1-inch cubes |
| Celery Stalks 🧅 | 3 whole | Cut into 1-inch pieces for soup |
| Celery Stalks 🧅 | 4 whole | Whole, for crispy crowns |
| Chicken Broth 💧 | 4 cups | Low-sodium preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
| Ground Nutmeg 🌶️ | ¼ tsp | Freshly grated preferred |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Olive Oil 🫒 | ¼ cup | For sautéing vegetables |
| Butter 🧈 | 2 tbsp | Unsalted, for extra richness |
The potatoes are the heart of this soup, so Russet potatoes are your best bet—they hold their shape while cooking. Costco or Walmart usually have them in bulk, and they’re worth the extra trip if you’re making a big batch. For the celery crowns, grab fresh, firm stalks—avoid any with wilted tops. Thyme and parsley can be fresh or dried (use half the amount if dried), but fresh herbs really elevate the flavor. The chicken broth should be low-sodium—you can always add more salt at the end if needed.
No heavy cream? Full-fat coconut milk works in a pinch, though it’ll have a slightly different flavor. Running short on thyme? Dried thyme or even oregano at half the amount will do. The celery crowns are the showstopper—if you don’t have enough whole celery, substitute with leeks or fennel for a similar effect. For the butter, European-style unsalted adds the most richness, but any unsalted butter will work. If you’re avoiding dairy, olive oil or vegan butter can replace the butter in the sauté step.
This soup tastes even better the next day—3-4 days in the fridge, no problem. For crispy celery crowns, air-fry them fresh after reheating the soup. Freeze portions without the celery crowns—they won’t crisp well after thawing. If you’re prepping ahead, store the celery crowns separately and crisp them right before serving. The velouté keeps well, so make extra for lunches all week.

Step-by-step instructions for creamy potato soup with crispy celery crowns
Here's how to create velvety potato soup with perfectly crispy celery crowns in your Ninja Foodi.
Sauté the Vegetable Base
Heat the 0.25 cup olive oil in the Ninja Foodi pot over medium heat. Add the diced yellow onions and cook for 3-4 minutes until they become translucent and just start to soften. This is your flavor foundation—don't rush it.
Add the minced garlic cloves and cook for another 30 seconds until fragrant. Here's the thing—garlic burns quickly, so keep an eye on it. Immediately add the 3 whole celery stalks cut into 1-inch pieces and the 2 lb russet potatoes cut into 1-inch cubes. Stir to coat everything in the oil, then sprinkle with 1 tsp salt and 0.25 tsp black pepper. This seasoning will infuse into the potatoes as they cook.
Build the Soup Base
Pour in the 4 cups chicken broth and stir well to combine. Scrape the bottom of the pot to release any browned bits—those contain flavor gold. Place the lid on the pot and select the Soup/Stew function with High Pressure for 10 minutes. This pressure cooking time transforms the tough potato skins into silky texture.
Once the cooking cycle completes, carefully release the pressure using the quick-release valve. The soup should be completely broken down and creamy-looking at this point. If it's too thick, add a splash of warm water or broth to reach your desired consistency. This is where the magic happens—the potatoes should be tender enough to mash slightly with a fork.
Finish with Cream and Herbs
Reduce the heat to low and stir in the 0.5 cup heavy cream, 0.25 cup fresh thyme leaves, 0.25 tsp ground nutmeg, and the remaining 0.5 tsp salt. The cream will make the soup luxuriously rich, while the nutmeg adds that warm, comforting depth. Let the soup simmer gently for 3-4 minutes—just enough time for the flavors to meld without curdling the cream.
Remove from heat and stir in the 0.25 cup fresh parsley. This herb adds brightness that cuts through the richness. Taste and adjust seasoning—you might need a pinch more salt or pepper depending on your broth. The soup should be creamy, flavorful, and perfectly balanced. Let it sit for 5 minutes before serving to allow the flavors to settle.
Create Crispy Celery Crowns
While the soup simmers, prepare the celery crowns. Preheat your oven to 400°F. Cut the 4 whole celery stalks into 1-inch thick rounds—this creates those beautiful crown shapes. Toss them in a bowl with 1 tbsp olive oil, 0.5 tsp salt, and 0.25 tsp black pepper until evenly coated.
Spread the celery crowns on a parchment-lined baking sheet in a single layer. Bake for 15-18 minutes until they're deep golden brown and crispy. Flip them halfway through for even browning. The key here is patience—they'll crisp up beautifully when they reach this color. Keep them warm in the oven while you serve the soup.
Assemble and Serve
Ladle the warm potato soup into bowls and top each serving with 2-3 crispy celery crowns. The contrast of creamy soup and crispy celery is what makes this dish special. Garnish with additional fresh parsley if desired. Serve immediately while the celery crowns are still crisp and the soup is piping hot.
Here's a pro tip: If you're making this ahead, you can prepare the soup base up to 2 days in advance and reheat it gently before adding the cream. Just store the celery crowns separately and crisp them up fresh before serving. The combination of creamy, velvety soup with those satisfying crunchy crowns is pure comfort food perfection.
Pro Tips For Making Potato Soup Recipe Ninja Foodi
- Sear the Onions First: The Ninja Foodi’s air fry function isn’t just for crisping—use it to caramelize onions and celery before adding liquid. Five minutes at 375°F with a splash of water gets them deep brown and sweet, way better than simmering. (Yes, even if it looks like you’re making onion jam.)
- Cut Potatoes Uniformly: Russets break down unevenly, so slice them into 1-inch chunks—not too thick, not too thin. The Foodi’s pressure cook setting needs consistent sizing to avoid mushy bits in some spots and undercooked lumps in others. I learned this the hard way when my first batch had a rock-hard potato in the middle.
- Salt the Potatoes Early: Add 1 teaspoon of salt to the raw potatoes before pressure cooking. It seasons them from the inside out and prevents blandness, especially if you’re skipping broth. Trust me, you’ll taste the difference—it’s not just about flavor, it’s about texture too.
- Finish with Butter and Roasted Garlic: Skip the raw garlic cloves in the soup—they’ll turn bitter. Instead, roast 4 whole cloves at 400°F for 15 minutes, then mash them into 2 tablespoons of cold butter before stirring into the finished soup. The richness and depth of flavor? Worth the extra 15 minutes. (Your taste buds will notice.)
Essential equipment for this dish
Ninja Foodi Pot
The Ninja Foodi 6-quart multi-cooker is your secret weapon for this recipe—it handles all three cooking phases seamlessly. The sauté function lets you develop deep, caramelized flavors in the onions and garlic without sticking, while the high-pressure cooker transforms tough potatoes into silky velouté in just 10 minutes.
I’ve tested this recipe in both the FXC901 (6-quart) and FXC902 (6-quart with air fryer lid)—both work perfectly, but the air fryer lid gives you that crispy celery crown finish without transferring to the oven. 🌡️
Air Fryer Lid
If you have the Ninja Foodi air fryer lid (included with FXC902 models), use it to crisp the celery crowns directly in the pot. Preheat the lid to 400°F for 3 minutes, then place the celery rounds on the rack and cook for 8-10 minutes, flipping halfway.
This saves oven space and keeps everything in one appliance. The lid’s even heat distribution ensures crispiness without burning. Pro tip: Line the rack with parchment paper for easy cleanup.
Immersion Blender
While the Ninja Foodi creates a naturally creamy texture from the potatoes, an immersion blender (like the Ninja BN601) ensures ultra-smooth velouté if you prefer it extra-silky. Pulse the soup after pressure cooking for 10-15 seconds—just enough to break down the potatoes while keeping some texture.
Avoid over-blending, or you’ll lose that comforting potato chunkiness. I keep one in my kitchen solely for soups and sauces. ✨
Measuring Cups
Precision matters with this recipe, especially for the heavy cream and chicken broth. Use liquid measuring cups (like the OXO Good Grips set) for the broth and cream to avoid spills, and dry measuring cups for the potatoes and onions.
I swear by the OXO stainless steel cups—they’re durable and easy to read. For the nutmeg, a microplane gives you the freshest, most flavorful grates without clumping. 💡
Baking Sheet
For the celery crowns, a half-sheet pan (13x18 inches) works best, but any rimmed baking sheet will do. Line it with parchment paper (not foil—it sticks!) for effortless cleanup.
If you’re short on space, use a wire cooling rack on top of the sheet to elevate the celery and promote even browning. I keep a half-sheet pan in my oven at all times for crispy toppings like these.
Tongs for Flipping
Use kitchen tongs (like OXO Good Grips) to flip the celery crowns halfway through baking—they grip better than spatulas and prevent crushing. For the sauté step, a wooden spoon** helps scrape up those flavorful browned bits from the Ninja Foodi pot.
I’ve ruined more celery crowns with a spatula than I’d like to admit, so tongs are a game-changer. 💪

Frequently asked questions
Can I make this potato soup without heavy cream?
For a lighter option, substitute the 0.5 cup heavy cream with 0.5 cup full-fat coconut milk or 0.25 cup Greek yogurt. The soup will still be creamy, though the texture will be slightly tangier. If you prefer a dairy-free alternative, cashew cream (blend soaked cashews with water) works beautifully too. Just reduce the broth by 0.25 cup to maintain balance.
Why does my Ninja Foodi potato soup turn out watery?
Watery soup usually happens when the potatoes release too much starch. After pressure cooking, let the soup sit for 5 minutes before adjusting—it thickens as it cools. If needed, simmer uncovered for 3-5 minutes to reduce. For extra thickness, mash 1-2 potato cubes against the pot sides with a wooden spoon to release starch. Never add flour or cornstarch—they make the soup gluey.
Can I use the Ninja Foodi air fryer lid for the celery crowns?
Yes! Preheat the air fryer lid to 400°F for 3 minutes, then place celery rounds on the rack. Cook for 8-10 minutes, flipping halfway. This keeps everything in one pot and saves oven space. Line the rack with parchment paper for easy cleanup—just don’t overcrowd or they’ll steam instead of crisp. The air fryer lid gives perfectly golden, crispy crowns without transferring to the oven.
How do I make this soup ahead of time?
Prepare the soup base up to 2 days in advance—just store it in the fridge without the cream or celery crowns. Reheat gently on the stove or in the microwave, then stir in the cream and herbs. For the celery crowns, crisp them fresh before serving (they won’t stay crispy when reheated). The velouté actually tastes better the next day as flavors meld! Freeze portions without the celery for up to 3 months.
What if I don’t have fresh thyme or parsley?
No problem! Use 0.125 tsp dried thyme (half the fresh amount) or 0.25 tsp dried oregano for depth. For parsley, swap with 0.25 cup fresh chives or 0.125 cup dried parsley. The key is balance—if using dried herbs, add them with the nutmeg at the end to preserve flavor. Fresh herbs brighten the dish, but dried versions work in a pinch for a similar aromatic profile.
