☑️ Storage Instructions

Fridge: Store leftover Tomato Bisque in an airtight container in the fridge for up to 4 days.

Freezer: Freeze the soup in a freezer-safe container for up to 3 months. Let it cool completely before freezing, and thaw in the fridge overnight before reheating.

Reheating: Warm the bisque on the stovetop over medium heat, stirring occasionally until heated through. If the soup thickens too much, you can simply add a splash of broth or cream.

💡 Tips for Making Low Carb Tomato Bisque

Roasting is key – Roasting the tomatoes, garlic, and onions deepens their flavor and adds a subtle caramelization that makes the bisque extra rich. Don’t skip this step, and be sure to stir halfway through for even roasting.

Use the right tomatoes – Campari tomatoes are ideal because they’re naturally sweet and low in acidity, giving the bisque a balanced, smooth flavor. If using other tomatoes, make sure they’re ripe to avoid a tart or bitter soup.

Don’t add cream too early – Wait until the end to add the heavy cream. Adding it too soon can cause it to break or curdle, especially if the soup is still too hot.

Let it simmer – After adding the broth and fresh basil, let the soup simmer to meld the flavors together. This step gives the bisque a richer depth that’s worth the extra few minutes.

🔄 Substitutions and Additions

  • Dairy-free: Use unsweetened coconut milk or almond milk instead of heavy cream if you’re looking for a dairy-free option.
  • Smoky twist: Mix in a bit of smoked paprika for a subtle, smoky flavor.
  • Other herbs: Try thyme or rosemary instead of basil for a different flavor.
  • Cheese: Use shredded mozzarella, cheddar, or gouda in place of parmesan for a cheesier bisque.
  • Spinach or kale: Stir in fresh spinach or kale during the final simmer for added greens.
  • Crumbled bacon: Top with crispy bacon for a salty, crunchy topping.
  • Sun-dried tomatoes: Add chopped sun-dried tomatoes before blending for an extra concentrated tomato flavor.
  • Fresh pesto: Swirl in a spoonful of fresh, homemade Pesto for a flavorful topping.

Can I Make the Bisque in Advance?

Absolutely! This Tomato Bisque can be made ahead of time and stored in the fridge for up to 4 days. The flavors will deepen as it sits, making it even tastier.

What If I Can’t Find Campari Tomatoes?

If Campari tomatoes are unavailable, you can substitute them with any fresh, ripe tomatoes, like Roma or beefsteak tomatoes. Just make sure to core and cut them into similar sizes for even roasting, and adjust the roasting time if using larger tomatoes.

Can I Use Canned Tomatoes Instead of Fresh?

You can, but trust me, fresh tomatoes provide the best flavor. If you can’t find rip and juicy tomatoes you can substitute with two 28-ounce cans of whole peeled tomatoes. Just drain the tomatoes and roast them.

Can I Freeze the Bisque with the Cream in it?

Yes, you can freeze the bisque with the cream added, but be sure to let it cool completely before freezing. When reheating, warm it slowly and stir frequently to avoid the cream separating.

What Can I Do If My Soup Tastes Too Acidic?

If your bisque tastes too acidic, try adding a pinch of granulated sugar substitute or a bit more cream to balance it out. Roasting ripe tomatoes also helps mellow out their acidity.

Can I Make this Bisque Without a Blender?

Yes! If you don’t have a blender, you can use a food processor, and immersion blender or even mash the roasted ingredients by hand for a chunkier texture. Just be sure to cook everything down well so it’s soft.

Do I Need to Peel the Tomatoes?

No need to peel the tomatoes before roasting. The skins blend up smoothly when puréed, especially if you use a high-powered blender.
