Transform simple vegetables into Ragusea-inspired richness with this smoky tomato base and celery crown finish.
| Ingredient | Amount | Notes |
|---|---|---|
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity variety preferred |
| Yellow Onions 🧅 | 1 whole | Medium-sized, finely diced |
| Garlic Cloves 🧄 | 4 cloves | Fresh, peeled and minced |
| Carrots 🥕 | 2 lb | Organic, medium-sized, peeled |
| Celery Stalks 🧅 | 4 whole | Fresh, for crowns and broth |
| Potatoes 🥔 | 2 lb | Yukon Gold, peeled and cubed |
| Canned San Marzano Tomatoes 🍅 | 28 oz | Crushed, high-quality variety |
| Vegetable Broth 💧 | 4 cups | Homemade or low-sodium store-bought |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, finely minced |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, finely chopped |
| Smoked Paprika 🌶️ | 1 tbsp | For smoky depth |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The San Marzano tomatoes and smoked paprika create the signature smoky depth. San Marzano cans are non-negotiable for that perfect balance of sweetness and acidity—Whole Foods or Trader Joe's carry the best brands. Fresh rosemary and thyme should be vibrant, not wilted; Costco sells them in bulk at a fraction of grocery prices. For the celery crowns, select thick, firm stalks—the ones with the widest diameter—since they'll be sliced into rings. The Yukon Gold potatoes are essential for their creamy texture when cooked; avoid russets, which can turn gummy.
No San Marzano tomatoes? Crushed plum tomatoes work in a pinch, but add 1 tsp sugar to balance the acidity. Fresh herbs wilt fast—dried thyme at one-third the amount is fine, but skip dried rosemary (it's too earthy). Substitute smoked paprika with liquid smoke at half the amount, though it's not identical. For a deeper umami kick, add 1 tbsp soy sauce or 1 tsp miso paste to the broth. The celery crowns can be prepped ahead—they'll keep crisp in the fridge for 3 days if stored in a sealed container with paper towels.
This soup tastes even better the next day—3-4 days in the fridge, sealed tightly. For longer storage, freeze portions in airtight containers for up to 3 months. Reheat gently on the stove, adding a splash of broth if needed. The celery crowns reheat best in a dry skillet for 2-3 minutes to maintain their crunch. Double the batch and freeze half; homemade soup is always better than takeout.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this soup—just chop, sauté, and simmer. The onions and garlic caramelize in that rich olive oil while the carrots and celery soften into perfect bite-sized pieces. No extra bowls, no fuss, just pure, satisfying simplicity.
- Umami Bomb: That slow-cooked onion base? It’s the secret weapon. The deeper the onions caramelize, the more complex the flavor becomes—sweet, savory, with just a hint of smokiness. Add the garlic at the end, and it’s like a flavor explosion in your mouth.
- Weeknight Workhorse: Between us, this soup is my go-to when I’m exhausted but still need to feed the family. It reheats beautifully, so I make a big batch on Sundays and have dinner covered all week. (Yes, even on a Tuesday night.)
- Budget-Friendly Hero: Carrots, celery, onions—these are the cheap staples that pack a punch. A single jar of ragusea sauce (or even homemade tomato paste) stretches this into five hearty bowls. No wasted ingredients, just pure, filling goodness.
Step-by-step instructions for Adam Ragusea's vegetable soup
This method delivers a rich, smoky tomato base with celery crown crunch—exactly as Adam Ragusea would prepare it.
Develop the Smoky Tomato Base
Heat the 0.5 cup extra-virgin olive oil in a large Dutch oven over medium heat. Add the 1 whole finely diced yellow onions and cook for 5 minutes until softened and translucent. Here's the thing—don't rush this step. You want the onions to caramelize slightly for deeper flavor.
Add the 4 cloves minced garlic and 1 tablespoon smoked paprika, stirring constantly for 1 minute until fragrant. Pour in the 28 oz crushed San Marzano tomatoes and bring to a gentle simmer. Reduce heat to low and let it cook uncovered for 20 minutes, stirring occasionally. This slow reduction builds the soup's rich, concentrated tomato flavor—the foundation of Ragusea's signature depth.
Build the Vegetable Medley
While the tomato base simmers, peel and cut the 2 lb carrots into ½-inch rounds and the 2 lb Yukon Gold potatoes into 1-inch cubes. These even-sized pieces ensure consistent cooking. Add them to the Dutch oven along with the 4 cups vegetable broth and 1.5 teaspoons salt. Bring to a gentle boil, then reduce heat to medium-low and let it simmer for 15 minutes.
Here's where texture matters: Add the 2 lb peeled carrots and 2 lb cubed potatoes to the simmering liquid. The potatoes should cook until tender but not mushy—fork-tender is the goal. The carrots will soften slightly but retain their structure. You'll know they're ready when they pierce easily with a knife but still hold their shape.
Prepare the Celery Crowns
While the vegetables simmer, cut the 4 whole celery stalks into 1-inch pieces and reserve the leaves for garnish. Trim the bottoms of the celery crowns and cut them into ½-inch thick rounds. Blanch these in boiling water for 1 minute, then shock in ice water to maintain their crisp texture. Drain well and set aside.
This blanching step is critical—it preserves the celery's crunch while preventing it from turning mushy during the final cooking. The contrast between the tender vegetables and crisp celery crowns is what makes this soup truly special. Keep them separate until the very end to maintain their texture.
Finish with Herbs and Season
Stir in the 0.25 cup finely minced fresh rosemary and 0.25 cup chopped fresh thyme along with the 0.5 teaspoon freshly ground black pepper. Simmer the soup for another 10 minutes to allow the herbs to infuse their aromatic qualities. Taste and adjust seasoning—this is where you ensure perfect balance. The soup should be rich but not overpowering, with the smoky paprika and fresh herbs shining through.
Real talk: The herbs should be noticeable but not dominant. If it needs more depth, add a pinch more salt or a splash of lemon juice. The goal is a harmonious blend where each element complements the others without competing.
Assemble and Serve
Just before serving, gently fold in the blanched celery crowns. Their crisp texture will contrast beautifully with the tender vegetables. Ladle the soup into bowls and garnish with 0.25 cup chopped fresh parsley. The parsley adds a final pop of color and freshness that ties the entire dish together.
Serve immediately while the celery crowns maintain their crunch. The smoky tomato base will have thickened slightly, coating each bite with its rich, complex flavor. This isn't just vegetable soup—it's a sophisticated dish that showcases how simple ingredients can create something extraordinary when prepared with care.
Pro Tips For Making Adam Ragusea Vegetable Soup
- Sweat the Onions Slowly: The Ragusa soup’s depth starts here—don’t rush the onions. Cook them in the olive oil over medium-low heat for 8-10 minutes until deep golden, almost caramelized, stirring occasionally. I used to blast the heat and end up with bitter, burnt bits that ruined the whole pot. Patience here means flavor that lingers.
- Mince Garlic Like Snow: Ragusa soup needs garlic to shine, but burning it is a fast way to kill the dish. Finely mince the cloves (or pulse in a food processor) and add them after the onions have softened—just before the celery and carrots go in. Too early, and they’ll turn bitter before the soup even simmers. I learned this the hard way after tasting a batch where the garlic tasted like nail polish remover.
- Cut Carrots and Celery Evenly: Ragusa soup is all about texture, so skip the haphazard chopping. Dice the carrots and celery into ¼-inch pieces—small enough to cook through but big enough to stay recognizable. Uneven pieces mean some will turn to mush while others stay crunchy. My grandmother’s trick: Use a mandoline for consistency, or at least take the time to eyeball each cut. It’s tedious, but the result is a soup where every bite has the same harmony.
- Simmer Gently After Adding Tomatoes: Once you add the tomatoes (or tomato paste), drop the heat to the lowest setting and let the soup bubble softly. Ragusa soup is about letting flavors meld, not racing to evaporation. I used to crank the heat after adding tomatoes, and the soup would either scorch or turn watery. A slow, steady simmer—no higher than a whisper of a boil—keeps the texture rich and the flavors balanced. Trust me, the extra 10 minutes now saves you from starting over.
Troubleshooting this recipe
Broth Too Thin?
If your soup ends up watery, don't panic—simmering reduces the broth naturally. For immediate thickening, mash 1 cooked potato directly into the pot using a potato masher. This creates a natural roux effect.
For future batches, reduce the vegetable broth by ½ cup or add 1 cup diced tomatoes (no liquid) to absorb excess moisture. 💧
Celery Crowns Mushy?
The key to crisp celery crowns is timing—blanch for exactly 1 minute and shock immediately in ice water. If they soften during cooking, try blanching for 45 seconds next time.
For extra crunch, toss them in 1 tsp olive oil and toast in a dry skillet at 350°F for 2 minutes before adding to the soup. 🥬
Flavor Too Mild?
Boost umami by adding 1 tbsp soy sauce or 1 tsp miso paste to the tomato base. For smokiness, increase smoked paprika to 1.5 tbsp or add ½ tsp liquid smoke**. Fresh herbs should be added late—wait until the final 10 minutes of cooking to preserve their bright flavors. 🌶️
Vegetables Overcooked?
Cut potatoes into 1.25-inch cubes and carrots into ½-inch rounds for even cooking. Start checking doneness 10 minutes before the recipe's suggested time. For extra insurance, remove the pot from heat 5 minutes early and let it rest covered—this carries over cooking just enough to reach perfect tenderness. ⏱️
Herbs Too Strong?
Fresh herbs can overpower if added too early. Always stir them in during the final 10 minutes of cooking. For milder flavor, use ½ the amount of dried herbs (if substituting) and remove stems completely. If needed, strain out some of the herb-infused broth before serving. 🌿
Smoky Flavor Missing?
The smoked paprika is crucial—don't skip it! For deeper smoke, add ½ tsp chipotle powder or 1 smoked garlic clove to the tomato base. If your paprika tastes bland, look for Spanish pimentón (like Pimentón de la Vera)—it has more complex smokiness than standard paprika. 🔥

Frequently asked questions
Can I make this soup without San Marzano tomatoes?
Yes, but you'll need to adjust for flavor balance. Use crushed plum tomatoes and add 1 teaspoon sugar to offset the acidity. For extra depth, stir in 1 tablespoon tomato paste with the onions. The smoky character will still shine through, though the sweetness won't be identical.
How do I store leftovers to keep the celery crowns crisp?
Store the soup and celery crowns separately. Keep the soup in an airtight container for up to 4 days in the fridge. Reheat the soup gently, then add the celery crowns fresh from the fridge—toss them in 1 teaspoon olive oil and toast in a dry skillet at 350°F for 2 minutes before serving. This maintains their crunch perfectly.
What vegetables can I substitute if I don't have Yukon Gold potatoes?
Use red potatoes for a waxier texture or sweet potatoes for natural sweetness. For a lighter option, swap in 1 cup diced butternut squash (add it with the carrots). Avoid russets—they'll turn gummy. The key is choosing vegetables that hold their shape when cooked.
Can I make this soup in an Instant Pot or pressure cooker?
Sauté the onions, garlic, and paprika as directed, then add all ingredients except the celery crowns. Pressure cook on high for 8 minutes, then quick-release. Finish with herbs and add the celery crowns just before serving. The pressure method cuts cooking time by half while keeping flavors rich.
Why does the recipe emphasize fresh herbs?
Fresh herbs release their aromatic oils during cooking, creating vibrant flavor that dried herbs can't match. The rosemary and thyme in this recipe should be finely minced to infuse properly. For dried substitutes, use one-third the amount (e.g., 1 teaspoon dried thyme instead of 0.25 cup fresh) and add them with the final 10 minutes of cooking.
