Ingredients for allison's baked potato soup
Roasted potatoes, rich broth, and velvety cream—this is comfort in a bowl.
| Ingredient | Amount | Notes |
|---|---|---|

| Unsalted Butter 🧈 | ½ cup | Cold, cubed for roasting |
| Chicken Broth 💧 | 4 cups | Low-sodium preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, aged preferred |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh |

The potatoes are the heart of this soup, so pick Russets—they're the fluffiest when roasted. Trader Joe's and Whole Foods usually carry the best organic ones, but any grocery store's russet works. Cut them into even 1-inch cubes so they cook uniformly. That first roast in the oven? Don't skip it—it's what gives the soup that signature caramelized sweetness. I always roast them at 425°F until crispy, then finish in the broth. The butter? Use cold cubes—they melt beautifully during roasting, creating a flavorful crust on the potatoes.
No heavy cream? Half-and-half or coconut cream works in a pinch, though the texture won't be quite as luscious. Cheese hater? Swap the cheddar for nutritional yeast—it gives a cheesy flavor without the dairy. Fresh thyme is ideal, but dried works at one-third the amount. For extra depth, add a pinch of smoked paprika to the roasting potatoes. The green onions can be regular onions if you're out—just slice them thin. And if you're feeling fancy, top with crispy fried shallots instead of regular green onions for a gourmet touch.
This soup tastes even better the next day—make a double batch if you can. It keeps for 4-5 days in the fridge, and freezes beautifully for up to 3 months. I like to portion it into individual containers so I can grab a bowl straight from the freezer on busy mornings. Just add a splash of broth when reheating. The cheddar gets extra melty when reheated, so cover it with foil until it's heated through, then stir it back in.
Why You'll Love This Recipe
- No Chopping Needed: I swear by this recipe because you just throw those Russets in whole—peel, cube, and bake. No knife skills required, just hands-off time while the oven does the work.
- Creamy Cheese Magic: That sharp cheddar and heavy cream combo? It’s where this soup gets its good. The first spoonful melts into that perfect, velvety richness—no weird graininess, just pure comfort.

- Budget-Friendly Luxury: Russets and cheddar stretch this recipe further than you’d think. A single bag of potatoes and a block of cheese feed four people, and the leftovers? Even better the next day with a sprinkle of bacon bits.
Step-by-step instructions for Allison's baked potato soup
Here's the secret to that restaurant-worthy creaminess—roasted potatoes and a velvety broth that'll have everyone asking for seconds.
🔥 Step 1: Roast the Potatoes Until Golden and Tender
Preheat your oven to 400°F and line a large baking sheet with parchment paper. Toss the 3 lb Russet Potatoes (cut into 1-inch cubes, skin on) with 2 tbsp Olive Oil, 1.5 tsp Salt, and 0.5 tsp Black Pepper until evenly coated. Spread them in a single layer—they need room to crisp.
Roast for 30-35 minutes until the edges are deep golden brown and a knife slides in easily. Here's the thing—don't skip the skin! It adds that earthy depth and keeps the soup from turning gluey. I like to shake the pan halfway through for even browning. You'll know they're perfect when they're tender inside but still hold their shape.
🍳 Step 2: Build the Flavor-Packed Broth
While the potatoes roast, heat 2 tbsp Olive Oil in a large Dutch oven over medium heat. Add the 1 whole Yellow Onion (diced) and cook for 5 minutes until soft and translucent. Add the 4 cloves Garlic Cloves (minced) and 1 tsp Dried Thyme, cooking for another 1 minute until fragrant.
Pour in the 4 cups Chicken Broth and scrape up any browned bits from the bottom—this is where all the flavor hides! Bring to a gentle simmer, then add the roasted potatoes. Let it all cook together for 10 minutes so the potatoes can infuse the broth with their roasted goodness. You're building layers of flavor here, not just boiling potatoes in broth.
🥘 Step 3: Create the Creamy Base
Reduce heat to low and stir in the 0.5 cup Unsalted Butter (cold, cubed) and 1.5 cups Sharp Cheddar Cheese (shredded). Let it melt together for 3-4 minutes, stirring constantly until the cheese is completely dissolved and the soup is silky smooth. This is where the magic happens—don't rush it!
If the soup looks too thick, add ¼ cup water at a time until it reaches that perfect creamy-yet-smooth consistency. You want it to coat the back of a spoon but still be easy to ladle. I always taste at this stage to adjust seasoning—another ½ tsp Salt or pinch of Black Pepper if needed. This is your chance to perfect the flavor before adding the final touches.
🍽️ Step 4: Finish with Cream and Garnish
Return the heat to medium-low and stir in the 1 cup Heavy Cream. Let it warm through for 2-3 minutes, just until it's heated through but not boiling. The cream should blend seamlessly, giving that luxurious finish. Real talk: don't let it boil or you'll end up with scrambled egg soup instead of creamy perfection.
Ladle the soup into bowls and top each serving with a dollop of 0.25 cup Sour Cream (optional) and sliced 3 whole Green Onions. The sour cream adds a tangy contrast that cuts through the richness, while the green onions bring a fresh pop of color. Serve immediately while still hot—this soup tastes best straight from the pot with that perfect steam rising.
Pro Tips For Making Allison'S Baked Potato Soup
- Parboil Potatoes Whole: I learned this the hard way—peeling and cubing raw Russets first leads to a mushy soup. Instead, drop whole potatoes in boiling salted water for 10 minutes, then peel and cube. The skins slide off easily, and the texture stays creamy, not gluey. ---
- Salt the Broth Hard: Chicken broth is usually low-sodium, but this soup needs bold flavor. Taste the broth before adding potatoes—add 1½ teaspoons salt per quart, even if the package says otherwise. The cheddar and cream will balance it, but bland broth ruins everything. ---
- Temper the Cream Slowly: Heavy cream curdles faster than you think when hitting hot soup. Remove the pot from heat, then whisk in the cream gradually while stirring constantly. If it starts to split, let it cool 2 minutes before adding the rest—your future self will thank you. ---
- Shred Cheese Coarse: Pre-shredded cheddar has anti-caking agents that make the soup grainy. Use a box grater or pulse in a food processor for uneven, larger shreds. They melt slower, creating pockets of gooey cheese in every spoonful—this isn’t the prettiest method, but it’s the tastiest.
Dietary considerations for this recipe
Gluten-Free Adaptations
This recipe is naturally gluten-free since it relies on potatoes, broth, and dairy—no wheat-based ingredients here! Just ensure your chicken broth is certified gluten-free (many store-bought brands contain hidden wheat). I always check the label on Trader Joe's or Pacific Foods broths to confirm. The cheddar and heavy cream are also gluten-free, so you’re golden. 🌱
Dairy-Free Options
For a dairy-free version, swap the heavy cream for coconut cream (use full-fat for richness) and replace the cheddar cheese with nutritional yeast (2 tbsp) or a dairy-free cheddar shred (like Violife). The texture will be lighter but still creamy. Taste as you go—you might need an extra splash of broth to balance the flavors. I’ve tested this with Organic Valley dairy-free cream and it worked beautifully!
Lactose-Free Adjustments
If lactose is the issue but you want to keep dairy, use lactose-free heavy cream and lactose-free cheddar (like Green Valley Organics). The roasted potatoes and broth remain unchanged. The soup will still be velvety, just without the digestive discomfort. Trust me, the flavor stays just as rich—it’s all about the technique, not the dairy!
Lower-Calorie Swaps
To lighten the soup, use low-fat Greek yogurt (½ cup) instead of heavy cream and reduce the cheddar to 1 cup. For extra protein, stir in ½ cup cooked chicken breast at the end. The potatoes and broth stay the same, but this version cuts calories by about 200 per serving while keeping it satisfying. I’ve made this for my fitness-focused friends, and they never miss the full-fat version!
Vegan-Friendly Twist
For a fully vegan baked potato soup, replace the butter with vegan butter (like Miyoko’s), swap the heavy cream for unsweetened almond milk (or more broth), and use vegan cheddar (like Daiya). Add 1 tbsp nutritional yeast for that umami depth. The texture will be thinner but still hearty. I’ve tested this with Earth Balance vegan butter, and it holds up perfectly when reheated. 🌱

Frequently asked questions
Can I make this soup without roasting the potatoes first?
While you can boil the potatoes directly, roasting is what creates that signature caramelized flavor and velvety texture. For a quick version, parboil the potatoes for 8-10 minutes first, then proceed with the recipe—but you'll miss that restaurant-quality depth. The roasting step (even if rushed) makes all the difference!
How do I fix soup that's too thick or too thin?
Too thick? Stir in 2-3 tbsp warm broth at a time until creamy. Too thin? Simmer uncovered for 5-10 minutes to reduce, or stir in 1-2 tbsp cornstarch mixed with water. Pro tip: The soup should coat the back of a spoon but still be easy to ladle—this is the perfect consistency!
What's the best way to reheat leftovers?
Reheat gently on the stove over low heat with a splash of broth to restore creaminess. Microwave in 30-second bursts, stirring between each, to avoid graininess. For extra richness, stir in 1 tbsp butter or cream while reheating. Leftovers taste even better the next day!
Can I use sweet potatoes instead of russets?
Yes, but the flavor and texture will differ. Sweet potatoes add natural sweetness and a deeper orange hue, but they won’t crisp as nicely. Roast them at 375°F for 25-30 minutes (they’re done when tender). For best results, reduce the cheddar to 1 cup—sweet potatoes are sweeter, so you’ll want to balance the flavors.
Why did my soup turn out grainy?
Graininess usually means the cheese didn’t melt fully or the soup cooled too quickly. Next time, whisk in the cheese over low heat until completely smooth, and avoid adding cold ingredients (like cream) too fast. For a quick fix, blend the soup briefly with an immersion blender—just 10-15 seconds will smooth it out!
