Ingredients
- 2 tablespoons olive oil (divided)
- 1 stalk of celery (about 10 ribs, root part trimmed off and discarded)
- 1 pound Yukon gold potatoes (peeled and diced)
- 5 ounces cremini mushrooms (sliced)
- 2 teaspoons dry thyme
- 7 cups water or vegetable stock
- 1 cup elbow pasta
- Salt and pepper to taste
- Paprika or red pepper flakes
- Fresh dill or parsley
- Extra virgin olive oil
Instructions
- Step 1: Cut the celery into thirds and arrange on a baking sheet. Drizzle with 1 tablespoon of olive oil and season with salt and pepper. Roast in the oven for 30 minutes.
- Step 2: Heat the remaining 1 tablespoon olive oil in a large pot over medium heat. Add the sliced mushrooms and cook for 8–10 minutes until softened. Season with salt and pepper.
- Step 3: Add the diced potatoes to the pot and cook for 5 minutes. Season with salt, pepper, and dry thyme. Stir and cook for 1 minute until fragrant.
- Step 4: Pour in the water or vegetable stock and bring to a boil. Reduce the heat and let it simmer for 20 minutes, or until the potatoes are tender.
- Step 5: Once the potatoes are fork-tender, scoop out half of them along with the roasted celery and place them in a food processor. Add a few spoonfuls of hot broth and blend until smooth.
- Step 6: Return the pot to a boil. Add the elbow pasta and the puréed celery and potatoes back into the soup. Cook until the pasta is al dente. Taste and adjust seasoning with salt and pepper.
- Step 7: Ladle the soup into bowls. Garnish with fresh dill or parsley, a sprinkle of paprika or red pepper flakes, and a drizzle of extra virgin olive oil if desired. Serve warm.
