Ingredients for baked potato and ham soup

Transform humble pantry staples into restaurant-quality soup with these carefully chosen ingredients.

The smoked ham is the soul of this soup—bone-in and skin-on delivers unmatched depth of flavor. Look for a well-marbled, thick-cut ham from the deli counter, preferably from brands like Hormel or Smithfield. If you can't find bone-in, use a leaner cut but add an extra 1/2 cup broth to compensate. The potatoes should be Russet or Yukon Gold—their waxy texture holds up better to long simmering. For the celery crowns, select stalks with vibrant green tops; these crisp beautifully when roasted. Trader Joe's often carries pre-trimmed celery with perfect crowns, saving you time.

No smoked ham? Substitute with high-quality ham hock or a smoked turkey leg, both of which add incredible depth when simmered. Running low on thyme? Fresh thyme works at a 1:3 ratio with dried, but if you're using dried, ensure it's culinary-grade from Penzeys or Spicewalla—the difference is noticeable. The broth is non-negotiable for flavor; homemade or high-end brands like Pacific Foods make all the difference. For extra richness, swap half the milk for whole coconut milk—it adds a subtle sweetness that pairs beautifully with the smokiness. The celery crowns can be prepped ahead and roasted separately; store them in the fridge for up to 3 days before adding to the soup.

This soup tastes even better the next day as flavors meld further. Store in an airtight container for up to 5 days in the fridge or freeze for 3 months. For meal prep, portion into individual containers—each serving reheats beautifully with a splash of broth or milk. The celery crowns can be reheated separately in a dry pan for 2-3 minutes to restore their crispness. Garnish with fresh parsley and a drizzle of high-quality olive oil to elevate the presentation. Leftovers? Double the batch and freeze half—perfect for lazy weeknight dinners.

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

This method delivers a rich, velvety soup with perfectly tender potatoes and crispy celery crowns.

Preheat your oven to 400°F. Place the 1.5 lb smoked ham on a baking sheet lined with parchment paper, skin-side up. Drizzle with the 2 tbsp extra-virgin olive oil and season with 0.5 tsp black pepper. Roast for 20 minutes until the skin begins to crisp and the ham reaches 145°F internally.

While the ham roasts, cut the tops off the 4 whole celery stalks to create crowns. Toss these crowns with 0.5 tsp black pepper and 0.5 tsp salt, then place them on the same baking sheet as the ham. Return to the oven for an additional 10-12 minutes until the celery crowns are golden brown and crispy. Remove from the oven and set aside.

In a large Dutch oven, heat 1 tbsp extra-virgin olive oil over medium heat. Add the 1 whole yellow onion and cook for 5 minutes until softened and translucent. Add the 6 cloves minced garlic and 1 tsp dried thyme, cooking for another 1 minute until fragrant.

Add the 3 lb russet potatoes cut into 1-inch cubes and stir to coat in the oil. Pour in the 6 cups low-sodium chicken broth and bring to a boil. Reduce heat to medium-low and simmer for 15 minutes until the potatoes begin to soften. Add the 2 whole bay leaves and remaining 1 tsp salt.

Remove the ham from the bone, discarding the bone and skin, and shred the meat into ¼-inch strips. Add the shredded ham to the Dutch oven along with the 1 cup whole milk and 0.5 cup heavy cream. Stir gently and simmer for 10 minutes until the potatoes are fork-tender and the soup has thickened slightly.

Remove the bay leaves and adjust seasoning if needed. The soup should be creamy but not overly thick—if it's too thick, whisk in 2-3 tablespoons of hot broth to reach your desired consistency. Keep warm over low heat.

Ladle the soup into bowls, garnishing each serving with the crispy celery crowns and 0.25 cup chopped fresh parsley. The contrast between the creamy soup, smoky ham, and crunchy celery crowns creates a perfect balance of textures and flavors.

Serve immediately with crusty bread on the side. The soup will continue to thicken slightly as it sits, so adjust seasoning just before serving if needed. Each spoonful should deliver rich, savory ham flavor with a velvety texture and satisfying crunch from the celery crowns.

Dietary considerations for this baked potato and ham soup

Gluten-Free Adaptations

This soup is naturally gluten-free if you use certified gluten-free ingredients. The key is checking your broth—opt for gluten-free chicken broth like Pacific Foods or Imagine Foods, both of which are certified.

Also, verify that your smoked ham is processed in a gluten-free facility, as some brands use gluten as an anti-caking agent. I’ve tested this recipe with Applegate Naturals ham, which is gluten-free and delivers fantastic flavor. 🥔

Low-Sodium Options

To reduce sodium, use low-sodium chicken broth and skip adding extra salt during cooking. The smoked ham already contributes significant sodium, so balance it with unsalted butter or olive oil instead of salted versions.

For extra flavor without sodium, add a pinch of black pepper or a dash of smoked paprika—both enhance the smoky profile. I often serve this with a side of pickled vegetables to add tangy contrast while keeping the soup light. 🧂

Dairy-Free Substitutes

For a dairy-free version, replace the whole milk and heavy cream with full-fat coconut milk or a cashew cream made from blended soaked cashews. I blend 1 cup soaked cashews with 1 cup water until smooth for a rich, creamy texture.

You can also use oat milk for a lighter option, though it may require a splash of lemon juice to balance flavors. The celery crowns and roasted ham will still shine through beautifully. 🥛

Vegetarian Adaptations

Swap the ham for smoked tofu or tempeh, both of which absorb smoky flavors well. Marinate the tofu in 1 tbsp soy sauce, 1 tbsp maple syrup, and 1 tsp liquid smoke for 30 minutes before roasting.

Alternatively, use mushrooms like portobello or shiitake for an umami-rich base. The potatoes and celery crowns will carry the dish, but the smoky depth from the ham substitute is essential. 🍄

Protein Boosts

Add ½ cup cooked lentils or ½ cup chickpeas for extra protein and fiber. These blend seamlessly into the soup and add a subtle earthiness that pairs well with the smoky ham.

For a meatier option, stir in ½ lb shredded rotisserie chicken or crumbled bacon in the final minutes of cooking. I love adding crumbled feta cheese on top for a salty, tangy finish. 💪

Kid-Friendly Tweaks

Make the soup smoother by blending it lightly with an immersion blender for a creamier texture kids love. Reduce the garlic and thyme slightly, and add a pinch of cinnamon or nutmeg for a subtle sweetness.

Serve with buttered noodles or toasted bread cubes for dipping. The crispy celery crowns can be omitted or replaced with roasted carrot coins for a gentler crunch. 👨‍👩‍👧‍👦
