Roasted Vegetable Soup

Featured in: Vegetarian Favorites

This velvety roasted vegetable soup transforms simple seasonal produce into something extraordinary through oven roasting. The high heat caramelizes carrots, sweet potatoes, bell peppers, and red onions, drawing out their natural sugars and creating deep, complex flavors.

After roasting to golden perfection, the vegetables simmer in aromatic broth before being blended into silky smoothness. Dried thyme, rosemary, and smoked paprika add warm, savory notes that complement the sweetness of the roasted vegetables.

The result is a nourishing bowl that's both hearty and elegant—ideal for cold weather meals but satisfying any time of year. Best of all, it comes together in just one hour and uses one baking sheet for minimal cleanup.

Recipe FAQ

What vegetables work best for roasting?

Root vegetables like carrots, sweet potatoes, and parsnips caramelize beautifully. Bell peppers, zucchini, onions, and garlic also develop wonderful sweetness. Choose vegetables that roast at similar rates for even cooking.

Can I make this soup ahead of time?

Absolutely. This soup actually tastes better the next day as flavors have time to meld. Store in an airtight container in the refrigerator for up to 3 days. Reheat gently over medium-low heat, stirring occasionally.

How do I get the smoothest texture?

An immersion blender works well directly in the pot. For ultra-smooth results, use a high-speed countertop blender in small batches, venting occasionally to release steam. Strain through a fine-mesh sieve after blending if you want restaurant-quality silkiness.

Can I add protein to make it more filling?

Stir in canned white beans or chickpeas during the last 5 minutes of simmering for added protein and fiber. You can also serve with crusty bread, grilled cheese sandwiches, or top with toasted nuts and seeds for extra sustenance.

What can I substitute for fresh herbs?

Dried herbs work perfectly here since they withstand roasting temperatures. Use 1 teaspoon dried for every tablespoon fresh. Thyme, rosemary, and oregano are excellent choices. Add fresh herbs as garnish right before serving for bright flavor.

Is this soup freezer-friendly?

Yes, freeze in portion-sized containers for up to 3 months. Leave a bit of space as liquids expand when frozen. Thaw overnight in the refrigerator, then reheat gently. The texture remains perfectly smooth after freezing and thawing.
