Step-by-Step Instructions
Preparation Steps
To start, gather your ingredients. This soup needs two cans of crushed tomatoes, one medium onion, two cloves of garlic, one carrot, and one celery stalk. Chop the onion, mince the garlic, and finely chop the carrot and celery. This helps all the flavors mix well.
Next, grab your slow cooker. Add the crushed tomatoes, chopped onion, minced garlic, carrot, and celery. Pour in four cups of vegetable broth. This broth adds depth and richness to the soup. Now, stir in one teaspoon of dried basil and one teaspoon of dried oregano. Add salt and pepper to taste. If you like a sweeter flavor, add one tablespoon of sugar.
Cooking Instructions
Now it’s time to cook! Cover the slow cooker and set it to low for 6-8 hours or high for 3-4 hours. The goal is to make the vegetables soft and full of flavor. You can go about your day while this soup cooks.
Blending and Final Touches
Once the cooking time is up, it’s time to blend. If you have an immersion blender, use it to puree the soup directly in the slow cooker. If you don’t, carefully transfer the soup in batches to a regular blender. Blend it until it’s smooth.
Now, stir in one cup of heavy cream or coconut cream. This will make your bisque rich and creamy. Taste the soup and add more salt and pepper if needed. Let the bisque simmer on low for another 30 minutes. This helps the flavors come together perfectly.
For presentation, serve your bisque in bowls. Garnish with fresh basil leaves and a drizzle of cream. Don’t forget some crusty bread for dipping!
Tips & Tricks
Enhancing Flavor Profiles
To make your bisque sing, focus on fresh herbs. Fresh basil adds a bright note. You can also toss in some fresh parsley or thyme for depth. Another tip is to roast your garlic before adding it. This brings out its sweet flavor. If you want a little zing, add a splash of balsamic vinegar or a pinch of red pepper flakes. These small changes can make a big impact!
Common Mistakes to Avoid
One common mistake is rushing the cooking time. Slow cooking lets all the flavors blend well. If you cook too fast, the soup may taste flat. Also, avoid skipping the sugar. It balances the acidity of the tomatoes. Lastly, be careful when blending. If you over-blend, you may lose that lovely texture. Aim for a creamy yet slightly chunky feel.
Adjusting Consistency and Thickness
The texture is key for a great bisque. If your soup is too thick, add more broth or cream. Mix it in slowly until it reaches the right smoothness. If it’s too thin, let it simmer longer with the lid off. This will help it thicken up. You can also add a little cornstarch mixed with water for a quick fix. Remember, it’s all about your taste and texture!

Variations
Vegan and Dairy-Free Options
To make the bisque vegan, just swap the heavy cream for coconut cream. This gives the soup a rich, creamy texture without dairy. Coconut cream adds a hint of sweetness, which works well with the tomatoes. You can also add a splash of lemon juice for extra brightness.
Spice it Up: Adding Heat
If you enjoy some heat, try adding red pepper flakes or diced jalapeños. Start with a small amount and taste as you go. This way, you control the spice level. Another option is to add a splash of hot sauce right before serving. This adds a nice kick without changing the soup’s main flavors.
Adding Protein for a Heartier Soup
To make the bisque more filling, consider adding protein. Cooked lentils or chickpeas work well. They boost nutrition and add texture. You can also add shredded chicken or turkey if you want meat. Just stir in the protein during the last 30 minutes of cooking. This ensures everything heats through nicely.
Storage Info
How to Store Leftovers
After enjoying your slow cooker tomato basil bisque, store leftovers in airtight containers. Make sure the soup cools first. This helps keep the flavor fresh. Place the containers in the fridge. The bisque stays good for up to five days. Always label your containers with the date. This way, you know when to eat it.
Freezing Instructions
To freeze the bisque, let it cool completely before packing. Use freezer-safe bags or containers. Remove as much air as possible to avoid freezer burn. The soup can last up to three months in the freezer. When you’re ready to eat, thaw it in the fridge overnight. This ensures safe and even thawing.
Reheating Guidelines
Reheat the bisque on the stove over medium heat. Stir it often to prevent sticking. If it’s too thick, add a splash of broth or water. You can also reheat it in the microwave. Just place it in a microwave-safe bowl and cover it. Heat in short bursts, stirring in between, until hot. Enjoy your warm, comforting soup!
FAQs
Can I use fresh tomatoes instead of canned?
Yes, you can use fresh tomatoes. Start with about 10-12 ripe tomatoes. First, peel and chop them. You want them to be juicy. Fresh tomatoes give a bright taste. If you choose fresh, cook the soup longer. This helps the flavors blend well.
What can I substitute for heavy cream?
You can use coconut cream for a vegan option. It will add a nice sweetness. Another option is to use whole milk or half-and-half. These will change the flavor a bit but still taste great. Silken tofu blended until smooth is also a good choice.
How long does the bisque last in the fridge?
The bisque lasts about 4-5 days in the fridge. Store it in an airtight container. Make sure to cool it down before putting it away. If you want to keep it longer, freeze it. It can last up to 3 months in the freezer.
