Many tomato soups rely on fresh or canned tomatoes, but roasting transforms their flavor in a way that’s rarely celebrated. When you slow-cook tomatoes in the crockpot, the natural sugars caramelize gently, filling your kitchen with a sweet, smoky aroma that’s almost hypnotic. This method turns simple ingredients into a deep, layered masterpiece without much fuss.
Using my crockpot for roasting might seem unconventional, yet it preserves every bit of flavor while freeing up stove space. As the tomatoes simmer, their bright acidity mellows into a rich, velvety base. The process feels almost meditative—a perfect way to embrace the coziness of seasonal cooking.
WHY I LOVE THIS RECIPE?

AVOID MY DISASTER (You’re Welcome)

- MISSED peeling the tomatoes? Strain the soup for a silky finish, or blend with skins for texture.
QUICK FIXES THAT SAVE YOUR DAY

Roasted Tomato Soup in the Crockpot
Equipment
- Crockpot
- Blender
Ingredients
- 2 pounds heirloom or ripe tomatoes roughly chopped
- 4 cloves garlic minced
- 2 tablespoons olive oil for roasting and sautéing
- 1 teaspoon sea salt to taste
- 1/2 teaspoon black pepper freshly ground
- 1 cup fresh basil leaves chopped, optional for garnish
Instructions
- Preheat your oven to 400°F (200°C) and toss the chopped tomatoes with a tablespoon of olive oil and a pinch of salt. Spread them on a baking sheet and roast for about 25 minutes until they are bubbly and slightly caramelized at the edges.
- While the tomatoes are roasting, heat a small amount of olive oil in a skillet over medium heat. Add the minced garlic and cook until fragrant, about 1 minute, until it becomes golden and aromatic.
- Transfer the roasted tomatoes into the crockpot, including any juices from the baking sheet. Add the sautéed garlic, remaining olive oil, salt, and black pepper. Stir lightly to combine.
- Set the crockpot to low and let the mixture simmer uncovered for 4-6 hours. During this slow cooking, the tomatoes will soften further, sugars will caramelize, and flavors will deepen, filling your kitchen with a rich aroma.
- Once the cooking time is complete, use an immersion blender directly in the crockpot to blend the soup until smooth and velvety. If you prefer a silky consistency, strain the soup through a fine sieve, pressing gently to extract all the flavor.
- Taste the soup and adjust seasoning with additional salt and pepper if needed. Ladle into bowls, garnish with chopped fresh basil if desired, and serve hot for a comforting, velvety tomato soup.
