AVOID MY DISASTER (You’re Welcome)

FORGOT to oil the roasting pan? The tomatoes stuck, but a splash of broth loosened the caramelized bits.
DUMPED the whole batch into the crockpot? It overfilled and spilled—use a large spoon to transfer, then lower heat.
OVER-TORCHED the garlic? It turned bitter; add a splash of cream or stock to mellow the flavor.
FORGOT to peel the tomatoes? No worries—blending smooth gets rid of the skins, no one notices.

Splash a little of your favorite olive oil on top while serving for extra shine and aroma.
Patch bitterness by stirring in a teaspoon of honey or maple syrup.

When in doubt, add a pinch of smoked paprika to deepen the smoky flavor—cracky and rich.

Ingredients Equipment Method Notes

Ingredients

2 pounds ripe tomatoes halved
2 cloves garlic minced
2 tablespoons olive oil for roasting and drizzling
1 teaspoon smoked paprika optional, for smoky depth
to taste salt and pepper
4 cups vegetable broth or chicken broth

Equipment

Oven or toaster oven
Slow Cooker
Blender or immersion blender

Method

Preheat your oven or toaster oven to 400°F (200°C). Arrange the halved tomatoes on a baking sheet, drizzle with olive oil, and sprinkle with a pinch of salt and pepper. Roast for about 30-40 minutes until the tomatoes are blistered and fragrant, filling the kitchen with a sweet, smoky aroma.
Once cooled slightly, transfer the roasted tomatoes to your slow cooker. Pour in the vegetable broth and add the minced garlic, smoked paprika (if using), and another pinch of salt and pepper. Stir gently to combine all the ingredients.
Cover the slow cooker and set it to low. Let the soup simmer for 2 to 3 hours so the flavors meld and the tomatoes break down further, filling your home with a cozy scent.
After simmering, use an immersion blender directly in the slow cooker to blend the soup until it's smooth and velvety. Alternatively, transfer the mixture in batches to a blender, then return it to the slow cooker.
Taste the soup and adjust the seasoning with more salt, pepper, or smoked paprika as desired. For an extra touch, drizzle with a little olive oil before serving for added shine and richness.
Serve the soup hot in bowls, garnished with fresh herbs or a swirl of cream if you like. Enjoy the rich, smoky flavor and creamy texture that makes this simple dish so satisfying.

Notes

For a hint of sweetness, stir in a teaspoon of honey or maple syrup if desired. You can also top with croutons or a sprinkle of grated Parmesan for extra flavor.
