There's something truly comforting about a bowl of warm, roasted vegetable soup, especially when it's brimming with the naturally sweet and smoky flavors that only roasting can bring. You'll want to make this recipe year-round. Let’s explore how to prepare this delicious roasted vegetable soup from scratch!
Ingredients You'll Need
- Fresh vegetables- Eggplant, zucchini, red onion, tomatoes, and carrots.
- Herbs and spices - Fresh basil and thyme, garlic, and aglio olio (Trader Joe's seasoning blend).
- Red lentils - This will add heartiness to the soup. It will also thicken it as the lentils break down and soften.
- Broth - Use chicken or vegetable broth.
- Olive oil - For sauteing + roasting.
- Trader Joe's Toscano cheese - For garnish (optional).
Steps for Making Vegetable Soup
Prepare the Eggplant and Vegetables
Step one: Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
Step two: Peel the eggplant and cut it into 1-inch cubes—place in a bowl. Add ¼ cup of olive oil, then season with salt and pepper. Toss to coat. Spread the eggplant evenly on the prepared baking sheet.
Step three: Add whole tomatoes to the baking sheet. Cut a head of garlic in half lengthwise and place the cut side on the baking sheet. Drizzle tomatoes and garlic with olive oil and season with salt and pepper.
Step four: Roast all ingredients in the oven for 20-25 minutes, or until the eggplant is tender and the tomatoes are slightly blistered.
Help tip: if using a dark baking sheet, roast at 400°F for 20-25 minutes.
Step five: Place the roasted tomatoes, garlic, and fresh basil in a blender. Process until smooth to create a creamy sauce.
Note: If you prefer a chunkier soup, skip this step and chop the tomatoes, garlic, and basil instead.
Step six: Drizzle enough olive oil to coat the bottom of your pot. Add the onion, carrots, zucchini, aglio olio, and thyme.
Step seven: Sautee until the onions have softened, about 5-7 minutes. Add the tomato puree, roasted eggplant, rinsed lentils, and 6 cups of broth. Stir to combine.
Final step: Place over high heat. Bring to a boil, lower the heat, and simmer for 30 minutes, stirring occasionally. Note: You will know when the soup is ready when the lentils have broken down and have completely softened.
How to Serve
Top this vegetable soup with a drizzle of olive oil, fresh basil, a sprinkle of aglio oglio seasoning, and freshly grated Toscano cheese. Serve alongside a fabulous salad like my spinach salad with apples and blue cheese, beet salad with goat cheese, or my red cabbage salad with Greek dressing.

Notes
Want it thicker and chunkier?
Cook longer to reduce the broth.
Don't have fresh tomatoes?
Use Hunt's diced fire-roasted tomatoes.
Want more veggies?
Add yellow squash, butternut squash, celeriac root, fresh summer corn, celery, or even a variety of potatoes. Whatever you choose, do not use cruciferous vegetables!

I’d give it 10 stars if I could! I used cherry tomatoes instead because that was what I had and I added potatoes. So delicious!
Joanne Davidson says
Just made this for dinner tonight, and it was absolutely excellent. Very flavourful and rich. Not difficult to make at all.
I just used regular homemade Italian seasoning and dried thyme, as I didn’t have the others. Will definitely be making this again. I might try adding some spinach at the end, and possibly increasing the red lentils as they are totally gone, but not because it needs it.
Ashley says
Joanne, that sounds delicious! Adding fresh spinach in the end sounds like the perfect finishing touch.
