You’re going to love this recipe because it takes the humble can of tomato soup and turns it into something truly special. Roasting the tomatoes first gives them a deep, almost sweet flavor that you just can’t get from a pot on the stove. And honestly, it’s so much easier than you’d think. We’re talking about throwing some things on a sheet pan and letting your oven do most of the work. It’s a healthy dinner recipe that feels indulgent, and it’s a fantastic base for all your favorite comfort soup recipes.
Equipements Needed
- Large rimmed baking sheet
- Large pot or Dutch oven
- Blender or immersion blender
- Cutting board and a good knife
Ingredients
- 3 lbs Roma tomatoes, halved (they have less water and more flavor)
- 1 large yellow onion, chopped (for a sweet, savory base)
- 6 cloves garlic, peeled (because is there ever too much garlic?)
- 3 tbsp olive oil (helps everything get roasty and delicious)
- 1 tsp dried oregano (adds that classic Italian herb flavor)
- 1 tsp salt, plus more to taste
- 1/2 tsp black pepper
- 4 cups vegetable broth (use chicken broth if you prefer)
- 1/2 cup fresh basil leaves, packed (for that bright, fresh finish)
- 1/2 cup heavy cream or half-and-half (makes it luxuriously creamy)
Step By Step
- Heat your oven to 400°F. On that large rimmed baking sheet, toss your halved tomatoes, chopped onion, and garlic cloves with the olive oil, oregano, salt, and pepper. Make sure everything is in a single layer.
- Roast for 30-35 minutes, until the tomatoes are soft and have some lovely browned spots. Your kitchen will smell amazing.
- Carefully scrape the entire contents of the baking sheet into your large pot. Add the vegetable broth.
- Bring the mixture to a simmer over medium heat and let it cook for about 10 minutes, so the flavors can get to know each other.
- Turn off the heat. Stir in the fresh basil leaves. Now, use your immersion blender right in the pot to puree the soup until it’s completely smooth. If you’re using a countertop blender, work in batches and please be careful with the hot liquid.
- Stir in the heavy cream. Taste it and add more salt or pepper if it needs it. And that’s it! So good.
Comforting Fall Soup Ideas
This roasted tomato basil soup is a star on its own, but it’s also the perfect start to a whole menu of fall soups and stews. For a real feast, serve it with a classic grilled cheese sandwich for dipping. It also pairs beautifully with a simple side salad for a lighter meal. If you’re looking for more fall dinner ideas, a hearty chili or a creamy potato soup would round things out perfectly on a chilly night.
Crockpot Cooking Instructions
Want to make this one of your easy crockpot soup recipes? You absolutely can. After roasting the tomatoes, onion, and garlic, scrape it all into your slow cooker. Add the broth. Cover and cook on LOW for 6-7 hours or on HIGH for 3-4 hours. Then, blend and stir in the basil and cream. It could not be simpler.
Variations & Substitutions
This recipe is wonderfully flexible. For a dairy-free version, swap the heavy cream for canned coconut milk. It adds a slight sweetness that’s just lovely. If you want a little kick, add a pinch of red pepper flakes with the oregano before roasting. And if fresh basil isn’t in the fridge, a tablespoon of pesto stirred in at the end is a great backup plan.
Storage & Reheating
Let the soup cool completely before storing. It will keep in an airtight container in the refrigerator for up to 4 days. You can also freeze it for up to 3 months, though I’d leave the cream out if freezing—add it when you reheat. To reheat, warm it gently on the stove over medium-low heat, stirring occasionally, until it’s hot all the way through.
Frequently Asked Questions
- Can I use canned tomatoes? You can, in a pinch! Use two 28-oz cans of whole, fire-roasted tomatoes if you can find them. Drain them well and skip the roasting step. Just sauté the onion and garlic in the pot before adding the canned tomatoes and broth.
- Is this one of those healthy soup recipes? It sure is! By roasting the vegetables, we’re building a ton of flavor without needing to add a lot of extra fat or salt. It’s packed with vitamins and, honestly, feels good to eat.
- My soup is a bit too acidic. What can I do? A tiny pinch of sugar or a drizzle of maple syrup can help balance the acidity of the tomatoes beautifully. Start with just 1/4 teaspoon and go from there.
