Ingredients Breakdown

Essentials

  • 2 lbs (900 g) ripe tomatoes, halved or quartered
  • 1 large onion, roughly chopped
  • 4 garlic cloves, peeled
  • 2 tablespoons olive oil, plus more for drizzling
  • 1 tablespoon tomato paste
  • 1 teaspoon sugar (optional, balances acidity)
  • 1 teaspoon dried oregano or thyme
  • 2 cups vegetable broth (or chicken broth)
  • 1/2 cup heavy cream (or coconut milk)
  • 1/4 cup fresh basil leaves, torn + extra for garnish
  • Salt and pepper to taste
  • Pinch of chili flakes (optional)
  • 2 cups bread cubes (day-old or stale preferred)
  • 2 tablespoons olive oil (for croutons)
  • 2 garlic cloves, minced
  • 1/2 teaspoon salt
  • 2 tablespoons parmesan or nutritional yeast (optional)

Pro Tips

  • If your tomatoes are out of season, add a handful of cherry tomatoes for sweetness.
  • Use a mix of herbs—thyme, basil, or even rosemary for added depth.
  • For a richer flavor, roast at 450°F for the last 5–10 minutes.
  • Use gluten-free bread for croutons if needed.
  • For a vegan bisque, substitute the cream with cashew cream or full-fat coconut milk.

Step-by-Step Instructions

  1. Preheat your oven to 425°F (220°C). On a large baking sheet, toss tomatoes, onion, and garlic with 2 tablespoons olive oil, tomato paste, sugar (if using), dried herbs, salt, and pepper.
  2. Roast for 25–30 minutes until tomatoes are blistered and onions are golden and caramelized. Garlic should be soft and fragrant.
  3. Transfer everything into a large pot. Add the broth and bring to a gentle simmer for 10–15 minutes to let the flavors meld.
  4. Stir in fresh torn basil and simmer another 2 minutes. Add chili flakes if you’re going for a little heat.
  5. Blend your soup until velvety smooth using an immersion blender. (Or transfer carefully in batches to a stand blender.)
  6. Stir in cream or coconut milk. Gently warm through, then taste and adjust seasoning. Splash in more broth if you like it thinner.
  7. Meanwhile, lower oven temp to 350°F (175°C). Toss bread cubes with olive oil, minced garlic, salt, and parmesan/nutritional yeast. Spread on a small sheet tray and bake 8–12 minutes, tossing halfway, until crisp and golden.
  8. Ladle soup into bowls, top with croutons, fresh basil, and optional drizzle of olive oil or basil oil. Serve hot and happy.

Chef’s Tips and Tricks

  • Make a double batch and freeze half—your future self will thank you.
  • Blend extra basil into olive oil for a gorgeous drizzle.
  • Let your blender run an extra 30 seconds for that ultra-silky texture.
  • Croutons getting soft? Pop them back in the oven for 2 minutes to re-crisp.
  • A splash of balsamic vinegar can add depth if your tomatoes were a little underwhelming.

Recipe Variations and Serving Suggestions

  • Vegan version: Use cashew cream or full-fat coconut milk instead of heavy cream.
  • Gluten-free: Swap bread for gluten-free or skip the croutons and top with toasted seeds.
  • Spicy twist: Add a dash of hot sauce or a sliced red chili to the roasting tray.
  • Serving idea: Top with a dollop of ricotta or swirl of pesto for extra luxe.
  • Make it a meal: Serve with grilled cheese or a leafy arugula salad with lemon vinaigrette.

FAQs

Can I use canned tomatoes instead of fresh?

Yes! Use high-quality whole peeled tomatoes (about two 14-ounce cans). Roast them right on the tray with onions and garlic just like fresh ones.

How long does it keep?

Store refrigerated in an airtight container for up to 5 days. Reheat gently over the stove or microwave.

Can I freeze this bisque?

Completely! Let it cool, then transfer to a freezer-safe container. Freeze up to 3 months. Just thaw and blend again before serving if texture changes.

Do I have to peel the tomatoes?

Nope! Roasting softens the skins, and once it’s blended, you won’t even notice. That’s one less step to worry about!
