Ingredients for baked potato soup recipe with half and half
Simple ingredients that transform into velvety perfection—roasted potatoes, rich broth, and just enough half and half.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Medium-sized, scrubbed clean |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred |
| Half and Half 🥛 | 1 cup | Full-fat for creamiest texture |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Celery Stalks 🥬 | 2 whole | Diced, about 1 cup |
| Butter 🧈 | 3 tbsp | Unsalted, for sautéing |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Sour Cream 🥛 | ¼ cup | For garnish (optional) |
| Chives 🌿 | 2 tbsp | Chopped, for garnish (optional) |
The potatoes are the heart of this soup, so pick firm, unblemished russets—they roast up sweeter and creamier. I always grab the organic ones from Trader Joe's when I can, but regular store-brand works too. Medium-sized potatoes (about 1.5 inches) ensure even cooking. Skip the waxy potatoes—they won’t mash as smoothly. Roasting them first brings out their natural sweetness, which is what makes this soup taste so rich without needing extra sugar. Pro tip: Don’t peel them—the skins add texture and nutrients.
No half and half? Heavy cream plus a splash of milk works in a pinch, but trust me on the full-fat version. The flour is just for thickening, so if you’re gluten-free, swap it for cornstarch (use half the amount). Fresh garlic and celery add depth, but frozen chopped celery from the freezer aisle saves time—just thaw it first. The broth matters too—Pacific Foods or Swanson low-sodium are my go-tos, but homemade works even better. For extra flavor, add a pinch of smoked paprika or a dash of Worcestershire sauce (check for vegetarian-friendly versions if needed).
This soup tastes even better the next day—honestly, the flavors meld into something magical. Keeps for 4-5 days in the fridge, but I usually make a double batch so I can freeze half for 3 months. Store it in airtight containers, and when reheating, add a splash of milk or broth to restore that silky texture. The sour cream and chives are just for topping, but don’t skip them—they add a bright, fresh finish that cuts through the richness. Leftovers reheat beautifully, though I prefer mine fresh out of the pot.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe because it’s literally one pot—no chopping like a fine-diner, no peeling mountains of potatoes. Just dice those Russets (skin on, if you’re lazy), toss ‘em in with the broth, and let the oven do the work. That half-and-half swirl at the end? Pure, effortless luxury.
- Creamy Without the Guilt: The half-and-half makes this soup dangerously rich, but here’s the secret: it’s balanced. The crispy potato edges from baking cut through the creaminess, and the onion-garlic base adds depth without overpowering. It’s the kind of dish that makes you want to lick the bowl—but you’ll still feel good about leftovers.
- Game for Any Occasion: This soup is my go-to for game days, lazy Sundays, or when my kid’s soccer team needs snacks. Serve it with crusty bread for a casual dinner, or pour it into mugs for a cozy brunch. Honestly, I’ve even reheated it cold from the fridge—still delicious, because the flavors hold up.
- Budget-Friendly Luxury: Russets and onions are cheap, and this recipe stretches easily for four servings. The half-and-half makes it feel fancy, but you’re not breaking the bank. Plus, leftovers reheat like a dream—just stir in a splash of broth if it thickens. My wallet and my taste buds win.
Step-by-step instructions for baked potato soup with half and half
Here's how to make this velvety, comforting soup that's smoother than store-bought.
Roast the Potatoes Until Fork-Tender
Preheat your oven to 400°F. Cut the 3 lb Russet Potatoes into 1-inch cubes—no need to peel them, the skins add texture. Toss the potato cubes with 1 tbsp olive oil (not in the ingredients list, but essential for roasting), 1 tsp salt, and ¼ tsp black pepper on a large baking sheet. Spread them in a single layer so they crisp nicely.
Roast for 40-45 minutes, flipping halfway through, until the edges are golden brown and the potatoes are completely tender when pierced with a fork. You want them to fall apart easily—this is the secret to that ultra-smooth texture. If they're not quite done, give them another 5-10 minutes in the oven.
Sauté the Aromatics for Flavor Foundation
While the potatoes roast, melt the 3 tbsp Butter in a large pot over medium heat. Add the 1 whole Yellow Onion (diced) and 2 whole Celery Stalks (diced) to the pot. Cook for 5-6 minutes until the onion is soft and translucent and the celery has just started to brown.
Add the 3 cloves Garlic Cloves (minced) and cook for another 30 seconds until fragrant. You'll smell that sweet, savory aroma—this is your flavor base. Don't let the garlic burn, or it'll turn bitter. If it starts to brown too quickly, reduce the heat slightly. Sprinkle in the 2 tbsp All-Purpose Flour and stir for 1 minute to cook off the raw flour taste.
Build the Creamy Base
Pour in the 4 cups Vegetable Broth and bring the mixture to a gentle simmer. Let it cook for 5 minutes to allow the flavors to meld together. Stir in the remaining ½ tsp salt and ¼ tsp black pepper to taste. Now, carefully add the roasted potatoes to the pot. The potatoes will break apart easily—this is what makes the soup so velvety.
Use an immersion blender to blend about half of the potatoes directly in the pot until the soup is smooth. If you don't have an immersion blender, transfer half the soup to a regular blender, blend until smooth, and then return it to the pot. You want some texture, but the soup should be mostly creamy. Simmer for another 5 minutes to let the flavors meld.
Finish with Creaminess and Garnish
Reduce the heat to low and stir in the 1 cup Half and Half. Let the soup simmer gently for 5 minutes—this ensures the cream heats through without curdling. Taste and adjust the seasoning if needed. The soup should be creamy, rich, and perfectly seasoned.
Ladle the soup into bowls and garnish with the 0.25 cup Sour Cream and 2 tbsp Chives. The sour cream adds a tangy contrast, and the chives give a fresh finish. Serve immediately while it's hot—this soup is even better the next day, but it's hard to wait!
Pro Tips For Making Baked Potato Soup Recipe With Half And Half
- Boil Potatoes Whole First: I learned this the hard way—peeling and chopping Russets before boiling turns them to mush. Drop them whole into salted boiling water for 15-20 minutes until a knife slides in easy. The skins stay intact, and you’ll get that perfect creamy texture without gummy bits.
- Sweat Onions Low and Slow: Skip the sizzle—cook onions over medium-low heat with a splash of broth until they’re translucent and just starting to caramelize. High heat burns them fast, and you’ll taste that bitter edge when you add the half and half. Patience here makes the soup taste richer.
- Temper the Half and Half: Cold cream straight into hot soup? That’s a curdling disaster. Warm the half and half in a separate saucepan until steaming (not boiling), then whisk it into the soup gradually. This keeps the soup velvety, not lumpy—trust me, your future self will notice the difference.
- Roast Garlic for Depth: Skip the raw minced garlic—roast 4 whole cloves at 400°F for 20 minutes until soft. Squeeze out the pulp and mix it into the soup after simmering. The caramelized sweetness balances the creaminess and cuts through the broth better than raw garlic ever could. (Yes, it’s more work, but it’s worth it.)
Flavor customization for this recipe
Creamy Variations
Swap the half and half for whole milk plus heavy cream (¾ cup milk + ¼ cup cream) if you prefer a lighter texture. For extra richness, use 1 cup heavy cream—it adds decadence but requires simmering at low heat to prevent curdling.
I’ve also tested coconut milk (full-fat) for a dairy-free option, though it gives a subtly tropical twist. 🥛
Spicy Kick
Add 1 tsp smoked paprika or ½ tsp cayenne pepper when sautéing the onions for warmth. For depth, stir in ½ cup diced chipotle peppers in adobo with the broth.
Top with crumbled bacon or green onions for a smoky-sweet contrast. Trust me, the heat balances beautifully with the creaminess. 🌶️
Cheesy Upgrade
Stir in 1 cup shredded cheddar or Gouda during the final 5 minutes of simmering for a melty, gooey texture. For a vegan version, use nutritional yeast (2 tbsp) or cashew cream (blend 1 cup soaked cashews + ½ cup water).
The half and half still shines—just add it last to avoid separation. 🧀
Herb Infusions
Fold in 1 tbsp fresh thyme or rosemary while roasting the potatoes for an earthy aroma. Finish with 1 tbsp chopped chives or parsley for brightness. A pinch of nutmeg (⅛ tsp) during the final simmer adds warmth without overpowering. Herbs elevate the dish without altering the creamy base. 🌿
Protein Boost
Add ½ lb cooked bacon, shredded rotisserie chicken, or crumbled sausage to the pot during the last 10 minutes of simmering. For a vegetarian option, stir in ½ cup cooked lentils or crumbled tofu (pressed and pan-fried first). The half and half’s creaminess complements proteins beautifully. 🍗
Seasonal Twists
In summer, add roasted zucchini or corn kernels for freshness. For fall, swap half the potatoes for sweet potatoes and a dash of cinnamon. Winter calls for caramelized onions and a splash of apple cider in the broth. Each variation keeps the half and half as the star. 🍂

Frequently asked questions
Why does roasting the potatoes first make the soup smoother?
Roasting breaks down the potato starches and creates a natural sweetness that blends seamlessly into the soup. When roasted until fork-tender, the potatoes collapse easily during blending, eliminating the need for heavy cream to mask graininess. The result is that signature velvety texture without lumps.
Can I make this soup without an immersion blender?
Transfer about half the soup to a regular blender first, blend until completely smooth, then return it to the pot. For extra texture, leave some chunks in the pot. Just be careful when blending hot liquids—leave room in the blender and vent the lid. The key is blending only about half the potatoes to maintain some body.
What's the best way to reheat leftover baked potato soup?
Gently reheat on the stovetop over low heat until warmed through, stirring occasionally. For extra creaminess, add a splash of half and half or milk while reheating. Microwave in 30-second intervals, stirring between each, to prevent separation. Never boil—this can cause the soup to curdle.
How can I make this soup dairy-free?
Replace the half and half with coconut milk (full-fat) or cashew cream (blend 1 cup soaked cashews + ½ cup water). For thickening, use cornstarch instead of flour. The flavor will be subtly different but still creamy. For extra richness, stir in 2 tbsp nutritional yeast during the final simmer.
Why does my soup sometimes get grainy?
Graininess usually happens when potatoes aren't fully cooked before blending or when adding cream too early. Always roast potatoes until completely tender first, and blend only half the potatoes for texture. Add cream at the very end and simmer gently to prevent curdling. If it happens, whisk in a little more broth or cream to smooth it out.
