Why You'll Love This Recipe

✓ Comfort in a Bowl: The roasted tomatoes give a deep, smoky sweetness that feels like a warm hug on a cool evening.

✓ One‑Pan Simplicity: Roast, blend, and simmer—all in two pans, so cleanup is a breeze.

I first discovered the magic of roasted tomatoes on a rainy night in Tuscany, when the kitchen smelled of caramelized herbs and the soup tasted like sunshine trapped in a bowl.

That experience taught me that a simple technique—roasting—can transform ordinary produce into extraordinary flavor, perfect for a quick weeknight dinner.

This creamy roasted tomato soup captures that depth while staying light, making it an ideal starter or a satisfying main when paired with crusty bread.

1 ½ cup raw cashews (soaked 4 hrs) Use pre‑soaked or boiled for speed
2 tbsp extra‑virgin olive oil For roasting; can replace with avocado oil
1 small onion, diced Yellow or sweet onion works best
2 cloves garlic, minced Adds aromatic depth
1 tsp smoked paprika Optional for extra smokiness
½ cup vegetable broth Low‑sodium preferred
¼ cup fresh basil leaves Torn, added at the end
Salt and freshly ground black pepper To taste

Instructions

creamy roasted tomato soup
1

Roast the vegetables

Preheat oven to 425°F (220°C). Toss tomatoes, onion, garlic, and olive oil on a sheet pan. Sprinkle with salt and smoked paprika. Roast 20‑25 minutes, turning halfway, until tomatoes are caramelized and fragrant.

Pro Tip: For extra depth, add a splash of balsamic vinegar before roasting.
2

Blend the base

Transfer roasted vegetables to a high‑speed blender. Add soaked cashews, vegetable broth, and fresh basil. Blend on high until ultra‑smooth, about 1‑2 minutes. The mixture should be thick yet pourable.

Pro Tip: Blend in batches if your blender is small; scrape sides for even texture.
3

Simmer and season

Pour the blended soup into a saucepan. Warm over medium heat for 8‑10 minutes, stirring occasionally. Adjust salt and pepper, and add a pinch more smoked paprika if desired. The soup should be velvety and hot.

Pro Tip: Do not boil; gentle simmer preserves the creamy texture.
4

Finish with fresh herbs

Stir in the remaining basil leaves just before serving. They add a bright, aromatic lift that balances the roasted richness. Optionally drizzle a teaspoon of extra‑virgin olive oil for glossy finish.

Pro Tip: Garnish with a pinch of flaky sea salt for texture contrast.
5

Serve and enjoy

Ladle soup into warm bowls. Pair with crusty sourdough, a simple side salad, or a grilled cheese sandwich. The soup stays silky for up to an hour, making it perfect for relaxed dining.

Pro Tip: Reheat gently over low heat; add a splash of broth if it thickens too much.

Expert Tips

Tip #1: Soak cashews efficiently

If short on time, pour boiling water over cashews and let them sit for 15 minutes; this yields the same creaminess as an overnight soak.

Tip #2: Roast at high heat

A hot oven (425°F) creates caramelized edges, intensifying tomato flavor without drying the flesh.

Tip #3: Adjust thickness

Add extra broth for a thinner soup or more cashews for a richer, thicker consistency.

Tip #4: Finish with acid

A squeeze of fresh lemon juice just before serving brightens the soup and balances richness.

Storage & Variations

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently, adding a splash of broth if needed. For a spicy twist, stir in a pinch of cayenne or a drizzle of harissa. Swap cashews for silken tofu for a lower‑fat version, or finish with a swirl of coconut cream for tropical flair.
