Ingredients You’ll Need
This recipe is built around a handful of wholesome, fresh ingredients, each playing a starring role. Roasting transforms every vegetable, coaxing out their natural sweetness and depth, while a few herbaceous touches add sunshine brightness. Trust me, these simple groceries create pure magic!
- Plum Tomatoes: Opt for 24 medium-large plum tomatoes; they roast beautifully and yield a rich, concentrated flavor that forms the heart of the soup.
- Sweet Onion: One large sweet onion adds mellow depth and a touch of natural sweetness.
- Fresh Fennel Bulb: This brings an aromatic, slightly licorice note that gives the soup its lovely complexity.
- Garlic: Four cloves, divided — some roasted, some sautéed — for those nutty and zesty undertones.
- Fresh Chopped Thyme: Three tablespoons; fresh thyme laces every bite with its gentle, earthy aroma.
- Fresh Basil: A quarter cup chopped, stirred in at just the right moment for a bright, herbal lift.
- Salt & Pepper: Essential for amplifying all the beautiful flavors.
- Extra Virgin Olive Oil: For roasting, sautéing, and that final silken drizzle; don’t be shy about using the good stuff.
- Chicken Broth: Adds just enough liquid, body, and savoriness to transform the roasted vegetables into a silky soup (vegetable broth works, too).
- Basil Pesto Mixed With Olive Oil or Grated Parmesan: Take your pick for a decadent, finishing garnish that makes every bowl special.
How to Make Roasted Tomato, Onion, And Fennel Soup
Step 1: Prep Your Oven and Baking Sheets
Before you get your hands messy, preheat your oven to 350 degrees F. Line two large baking sheets with aluminum foil, which will make cleanup way easier and keep your vegetables from sticking as they caramelize. This step sets the stage for roasting the stars of our Roasted Tomato, Onion, And Fennel Soup.
Step 2: Ready the Tomatoes
Slice all your plum tomatoes in half, then lay them cut side up on one of your prepared baking sheets. Mince half of your garlic and fresh thyme together—don’t be afraid to get aromatic here. Sprinkle this fragrant mixture over the tomatoes. Generously drizzle olive oil over the cut side and finish with a dusting of salt and pepper. This early seasoning ensures your tomatoes soak up maximum flavor while roasting.
Step 3: Prepare the Onion and Fennel
Peel your sweet onion and cut it into one-inch slices, keeping the slices as intact as possible. Brush both sides with olive oil so they caramelize rather than burn. For the fennel, trim off the fronds and core the bulb, then slice it up. Toss the sliced fennel with olive oil and place everything—onions and fennel—on the second baking sheet. Give them a sprinkle of salt and pepper for good measure.
Step 4: Roasting Time
Slide both baking sheets into the oven. Your tomatoes will need about 40 minutes, while the onions and fennel might need closer to an hour. Keep an eye on them, looking for those telltale edges of golden brown and tender, jammy flesh. Roasting concentrates the flavors, making every spoonful of Roasted Tomato, Onion, And Fennel Soup taste like pure summer.
Step 5: Blend into a Chunky Base
Once your veggies are soft and beautifully colored, pile them into your food processor. Pulse until you have a thick, chunky mixture. Don’t go too far; you want a bit of texture so the soup doesn’t turn to broth. If you prefer a creamier texture, add a splash of broth and blitz until it’s your perfect consistency.
Step 6: Sauté Garlic and Combine
Heat two more tablespoons of olive oil in a heavy saucepan over medium. Finely mince the remaining garlic cloves and toss them in, cooking until just fragrant. Add in the roasted veggie mixture from the food processor, along with the fresh basil. Pour in enough chicken broth (about one cup) to loosen the soup—add more later if you want it thinner.
Step 7: Simmer and Finish
Bring everything to a gentle boil, then turn the heat down to let it simmer for about 10 minutes. This final simmer unites all the deep flavors of Roasted Tomato, Onion, And Fennel Soup. Taste, and add more salt and pepper if needed. If the soup thickens too much while simmering, just add more broth. Let the soup cool to room temperature for optimal flavor and serving texture.
Step 8: Serve with Garnish
Ladle the soup into bowls once it’s cooled down a bit. Finish each serving with a spoonful of pesto mixed with olive oil for an herby flourish, or simply a shower of grated Parmesan if you want to go extra savory. This finishing touch is what takes Roasted Tomato, Onion, And Fennel Soup utterly over the top.

Garnishes
The crowning glory makes all the difference. For this Roasted Tomato, Onion, And Fennel Soup, try a swirl of basil pesto melted into olive oil, letting the vibrant green ribbon across each bowl. Or sprinkle with freshly grated Parmesan for that salty, nutty finish. For something extra fresh, a few reserved fennel fronds or tiny basil leaves both add elegance and flavor.
Side Dishes
Pairing makes the meal shine. This soup is marvelous with slabs of crusty bread or cheesy garlic toast for dipping. A bright green salad with lemony vinaigrette keeps things light, while a grilled cheese sandwich transforms your bowl into true comfort food. Honestly, Roasted Tomato, Onion, And Fennel Soup adapts beautifully to any meal, from casual lunches to dinner parties.
Creative Ways to Present
Wow your guests by serving the soup in small cups or shot glasses as an elegant amuse-bouche at your next gathering.

For summertime, serve Roasted Tomato, Onion, And Fennel Soup chilled in petite bowls, topped with a dollop of whipped ricotta and a drizzle of pesto.
Make Ahead and Storage
Storing Leftovers
If you find yourself with extra soup, you’re in luck! Once the Roasted Tomato, Onion, And Fennel Soup cools to room temperature, pour it into an airtight container and store it in the fridge. It’ll keep beautifully for up to four days, and the flavors only deepen as they mingle.
Freezing
This soup is a freezer’s best friend. Ladle cooled Roasted Tomato, Onion, And Fennel Soup into freezer-safe containers or zip-top bags (leave a little space for expansion). Label, date, and freeze for up to three months. When the craving strikes, you’ll have a bowl of sunshine ready to go.
Reheating
To reheat, simply transfer your desired amount to a saucepan and warm over low-medium heat until gently simmering. Add a splash of broth or water to loosen if needed. If reheating from frozen, thaw overnight in the fridge first, or gently heat straight from frozen, stirring occasionally for even warmth.
FAQs

What can I do if my soup is too thick?
No worries! Just stir in a little extra broth or even a splash of water until you achieve your desired consistency. This soup is meant to be versatile and forgiving.
Can I serve this soup chilled?
Yes! Roasted Tomato, Onion, And Fennel Soup is surprisingly refreshing when served cold, especially in the summertime. Let it cool completely in the fridge and add your favorite garnishes just before serving.
