Ingredients for baked potato and ham soup

Humble potatoes and crispy celery crowns transform into restaurant-quality soup with these 13 ingredients.

The potatoes are the heart of this soup—Russet potatoes work best for their fluffy texture. Grab a 3-pound bag from the grocery store's produce section (they usually sell them pre-washed). For the ham, bone-in cuts add extra flavor, but any cooked ham will do. The celery and onions deserve special attention here: roasting them until golden creates that signature crispy crown. Trader Joe's often has pre-cut celery and onion bundles that save time, but whole stalks keep longer. Fresh herbs are non-negotiable—the parsley and thyme need to be bright green, not wilted. If you're short on time, dried herbs work at half the amount, but fresh gives that restaurant-quality aroma.

No heavy cream? Half-and-half or coconut cream works in a pinch, though the texture won't be as rich. Short on chicken broth? Vegetable broth plus a splash of soy sauce mimics the savory depth. The ham can be swapped for smoked turkey or even extra crispy tofu for a vegetarian version (though the flavor will differ). For the crispy celery crowns, don't skip the roasting step—this is what makes this soup special. If your celery is stringy, peel it first. The butter used for roasting should be cold and cubed—this ensures maximum crispiness without burning. For the thickening, cornstarch or a roux are alternatives, but flour blends seamlessly into the creamy base.

This soup tastes even better the next day as flavors meld. Store in an airtight container for 4-5 days in the fridge or freeze for up to 3 months. To reheat, warm on the stove over medium heat—add a splash of broth or milk if it gets too thick. The crispy celery crowns will soften slightly but still add texture. For meal prep, double the batch and freeze portions—single-serving containers are perfect for lunches. The leftovers reheat beautifully, making this an ideal make-ahead dish for busy weeks.

Step-by-step instructions for baked potato and ham soup

Here's how to create a velvety potato soup with crispy celery crowns and rich herb swirls.

Preheat your oven to 400°F. Cut the 3 lb Russet Potatoes into 1-inch cubes (skin on for texture) and trim the 4 whole Celery Stalks into 1-inch pieces. Toss both with 0.5 cup Unsalted Butter, 1 tsp Salt, and 0.25 tsp Black Pepper until evenly coated.

Spread the potatoes and celery on two rimmed baking sheets in a single layer. Roast for 30 minutes, stirring once halfway through. The potatoes should be tender when pierced with a fork and the celery golden brown at the edges. This roasting step builds flavor that simmering alone can't match.

In a large Dutch oven, melt 0.25 cup Unsalted Butter over medium heat. Add the 2 whole Yellow Onions (chopped) and cook for 5 minutes until softened and translucent. Stir in the 4 cloves Garlic Cloves (minced) and cook for 30 seconds until fragrant—don't let it brown or it'll turn bitter.

Add the roasted potatoes and celery to the pot, then pour in 6 cups Chicken Broth. Bring to a boil, then reduce heat to low and simmer for 20 minutes, stirring occasionally. The soup should thicken slightly, and the potatoes should be fork-tender throughout. Add the 1 lb Cooked Ham (diced) and simmer for another 5 minutes to heat through.

In a small bowl, whisk together the 2 tbsp All-Purpose Flour and 0.5 tsp Salt. Gradually whisk this into the simmering soup while stirring constantly. Cook for 3-4 minutes until the soup thickens to your preferred consistency—it should coat the back of a spoon but remain smooth.

Remove the pot from heat and stir in the 1 cup Heavy Cream, 0.25 cup Fresh Thyme, and 0.25 cup Fresh Parsley. Taste and adjust seasoning with additional salt or black pepper if needed. The soup should be rich, creamy, and perfectly balanced between savory ham and earthy herbs.

While the soup simmers, cut the remaining 1-inch celery pieces (from the roasted batch) into ¼-inch thick rounds. Toss them with 1 tbsp melted butter and 0.25 tsp salt, then spread on a parchment-lined baking sheet. Broil on high for 2-3 minutes until deep golden brown and crispy—watch closely to avoid burning.

Serve the soup immediately in deep bowls, topped with the crispy celery crowns and a swirl of the herb-infused cream. The contrast between the creamy soup and crispy celery adds texture that makes this dish truly special. Each spoonful delivers the perfect balance of hearty potato, savory ham, and aromatic herbs.

Flavor customization for this dish

Spicy Kick

Add 1-2 teaspoons of smoked paprika or ½ teaspoon cayenne pepper when roasting the potatoes and celery for a smoky, spicy depth. For heat lovers, stir in 1 tablespoon of hot sauce (like Cholula) with the heavy cream at the end.

I like adding a pinch of Penzeys' Jamaican jerk seasoning for complexity—just ½ teaspoon does the trick. 🌶️

Smoky Depth

Swap the ham for smoked turkey breast or add ½ cup of liquid smoke to the broth for a campfire-like flavor. I also love tossing the crispy celery crowns with 1 teaspoon of chipotle powder before broiling.

For extra smokiness, char the onions slightly in a dry pan before sautéing them—this adds a caramelized, smoky note that pairs perfectly with the creamy soup.

Creamy Variations

For a lighter version, replace the heavy cream with ½ cup coconut milk and ½ cup Greek yogurt—it stays creamy but adds tang. If you prefer extra richness, stir in ¼ cup sour cream at the end.

I’ve also experimented with nutritional yeast (1 tablespoon) for a cheesy, umami boost without dairy. 🥛

Herb Swaps

Swap the thyme for rosemary or sage for an earthy twist—just use ½ teaspoon dried (or ¼ cup fresh). For brightness, add 1 tablespoon of fresh dill or 1 teaspoon of dried tarragon with the parsley.
