1-First Step: Preheat and Prep the Celery Start by preheating your oven to 400°F (204°C) to get that perfect roast going. Cut the celery into thirds, drizzle it with 1 tablespoon of oil, and season it with salt and pepper for a flavorful kick. This roasting step, which takes about 30 minutes, brings out the natural sweetness of the celery, making your roasted celery potato soup extra tasty and creamy without any dairy.

2-Second Step: Sauté the Mushrooms While the celery roasts, grab a large pot and heat the remaining 1 tablespoon of oil over medium heat. Add the sliced cremini mushrooms and sauté them for 8-10 minutes, seasoning with salt and pepper as they cook. This step builds a savory base for your potato soup, ensuring every bite is packed with earthy goodness think of it as layering flavors like you would with your favorite grilled meats!

3-Third Step: Add and Cook the Potatoes Once the mushrooms are golden, toss in the diced Yukon gold potatoes and cook them for about 5 minutes, stirring occasionally. Season everything with a bit more salt, pepper, and the 2 teaspoons of dry thyme, letting it cook for another minute until the herbs release their aroma. This process, which takes roughly 5-6 minutes total here, helps meld the flavors in your roasted celery potato soup, creating that comforting warmth perfect for chilly evenings.

4-Fourth Step: Simmer the Soup Base Pour in the 7 cups of water or vegetable stock, bring it to a boil, then reduce the heat to simmer for about 20 minutes until the potatoes are tender. Keep an eye on it to avoid overcooking timing is key for that ideal texture. If you’re adapting for dietary needs, like making it vegan, just ensure your stock is plant-based to keep this roasted soup light and healthy.

5-Fifth Step: Blend and Combine After simmering, scoop out half of the potatoes into a food processor along with the roasted celery and some broth, then blend until smooth. This creates a creamy consistency that makes the soup feel indulgent without extras. For variations, you could add items like carrots or beans at this point, as mentioned in the tips, to customize your roasted celery potato soup based on what’s in your kitchen.

6-Final Step: Finish and Serve Return the blended mixture to the pot, bring the soup back to a boil, and add the 1 cup of elbow pasta. Cook until the pasta is al dente, which takes about 8-10 minutes, then adjust the seasoning to taste.
