STEP-BY-STEP INSTRUCTIONS:
-
Preheat the oven: Set the oven to 425 degrees F.
-
Prepare the asparagus: Toss the asparagus with 1 tablespoon olive oil, 1/2 teaspoon kosher salt, and 1/4 teaspoon black pepper on a sheet pan. Spread the asparagus into a single layer. Roast for 8 minutes until the asparagus turns bright green. Reserve about 10-12 asparagus tops to garnish the soup.
-
Sauté the onion and garlic: In a large saucepan or Dutch oven, heat 1 tablespoon olive oil over medium heat. Add the chopped onions and sauté for 5 minutes until they start to soften.
-
Add garlic and seasonings: Stir in the minced garlic, 1/2 teaspoon kosher salt, and 1/4 teaspoon black pepper. Continue cooking for about 1 minute until fragrant.
-
Combine remaining ingredients: Add the roasted asparagus, diced potatoes, baby spinach, and vegetable broth to the saucepan. Bring the mixture to a boil, then reduce the heat and let it simmer for 15-18 minutes, or until the potatoes are tender.
-
Blend the soup: Carefully transfer the soup in batches to a blender and puree until smooth. Alternatively, you can use an immersion blender directly in the pot.
-
Reheat and serve: Return the pureed soup to the saucepan to reheat if necessary before serving. Divide the soup into bowls and garnish with the reserved asparagus tops, chopped parsley, flaky sea salt, and additional black pepper as desired.
HOW TO SERVE Roasted Asparagus Soup
This roasted asparagus soup can be served warm for a comforting meal. If you want to keep things healthy, pair it with a side salad or whole-grain crackers for added fiber. Portion control is also key—aim to serve yourself just one bowl at a time to help manage calorie intake, especially if you’re focused on weight loss. A portion size of about 1 to 1.5 cups is a balanced amount that allows you to enjoy the soup without overindulging.
STORAGE & FREEZING: Roasted Asparagus Soup
If you have leftovers, you can store the soup in an airtight container in the fridge for up to 4 days. Alternatively, this soup freezes beautifully! Just make sure to let it cool completely before transferring it to a freezer-safe container. When properly stored, it can last up to 3 months in the freezer. To reheat, simply thaw overnight in the fridge and warm on the stove over medium heat before serving.
SERVING SUGGESTIONS
This soup pairs well with a variety of healthy side options. For a balanced meal, consider serving it with a slice of whole-grain bread for extra fiber or a light arugula salad dressed with lemon vinaigrette. For added protein, try adding a small side of grilled chicken or a handful of chickpeas for a vegetarian twist.
VARIATIONS
-
Healthier Version: For an even healthier version, skip the olive oil during the sautéing process and use vegetable broth instead. You can also include more vegetables such as carrots or celery for added nutrition.
-
High-Protein or Low-Carb Version: To boost protein, you can add cooked lentils or white beans to the soup. This not only elevates the protein content but also makes the soup heartier. If you want a low-carb option, replace the potato with cauliflower to keep it low in carbs and high in fiber.
-
Air Fryer Version: For an air fryer version, use the air fryer to roast the asparagus at 400 degrees F for about 7 minutes, tossing halfway through. Follow the same sautéing and soup-making instructions as above.
