Roasted Vegetable Soup

Featured in: Moss-Earthy Weeknight Meals

This roasted vegetable soup transforms simple seasonal produce into a luxurious, velvety bowl of comfort. The secret lies in oven-roasting carrots, sweet potatoes, bell peppers, zucchini, red onion, and garlic at high heat until they caramelize and develop deep, concentrated flavors. After roasting, everything simmers in vegetable broth before being blended into silky smoothness. The result is naturally sweet from the roasted vegetables, with smoky undertones from paprika and earthy notes from thyme and rosemary. Ready in just one hour, this soup stores beautifully for days and adapts easily to whatever vegetables you have on hand.

Recipe Frequently Asked Questions

Can I use different vegetables than what's listed?

Absolutely. This soup works beautifully with parsnips, butternut squash, leeks, cauliflower, or any seasonal vegetables you have available. Keep the total amount roughly the same for consistent results.

How do I make the soup creamier without dairy?

Stir in a splash of full-fat coconut milk before blending for a creamy, dairy-free version. You can also add a peeled potato while roasting for natural creaminess.

Can I freeze this soup?

Yes. Let the soup cool completely before transferring to airtight containers or freezer bags. Freeze for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop.

What's the best way to achieve the smoothest texture?

An immersion blender makes quick work of smoothing the soup directly in the pot. For an ultra-silky result, use a high-speed countertop blender and strain through a fine-mesh sieve after blending.

How long does the soup keep in the refrigerator?

Stored in an airtight container, the soup stays fresh for up to 3 days. The flavors actually deepen and improve after a day or two, making it ideal for meal prep.

Can I make this soup without an oven?

You can sauté the vegetables in a large pot until tender and caramelized, then add broth and simmer. The flavor will be slightly different, but still delicious.
