Required Ingredients

To create a flavorful keto tomato soup, the selection of ingredients is crucial. Here’s a breakdown of the essential components needed to achieve the perfect low carb tomato soup.

Canned Tomatoes

For the base of the soup, use one can (28 ounces) of whole plum tomatoes, with San Marzano tomatoes being the preferred choice due to their rich flavor and low acidity. These tomatoes are renowned for their sweetness and are less likely to introduce any unwanted bitter or metallic tastes often found in lower-grade canned tomatoes. If San Marzano tomatoes are not available, any high-quality canned tomatoes that are grown and imported from Italy will suffice.

Fresh Basil

Incorporating fresh basil not only infuses the soup with a vibrant, fresh flavor but also complements the tomatoes beautifully, transforming the dish into a delightful tomato basil soup. About 1/4 cup of prepared basil pesto can be added for an intensified basil presence, and additional fresh basil leaves can be used for garnishing.

Additional Spices

To enhance the soup’s flavor profile, consider adding a 1/4 teaspoon of dried basil leaves. For those who enjoy a bit of heat, a spoonful of red curry paste or a pinch of chili can be introduced into the mix. Other spices like black pepper, dried oregano, paprika, cumin, Herbs de Provence, thyme, or oregano are also excellent additions that can be adjusted according to taste to create a more personalized flavor experience.

By carefully selecting these ingredients, one ensures that the keto tomato soup will be both delicious and compliant with a low-carb diet.

Roasting Tomatoes for Enhanced Flavor

Choosing Tomatoes

For roasting, selecting the right type of tomatoes is crucial to enhance the flavor of your keto tomato soup. Roma or plum tomatoes are ideal due to their meaty texture, which results in less watery and more flavor-concentrated roasted tomatoes. These varieties hold their shape better and caramelize beautifully when exposed to high heat. Although Campari tomatoes are a suitable alternative, they are more delicate and may burst during cooking. If available, cherry tomatoes or grape tomatoes can also be used, but they should be monitored closely as they roast quicker, typically taking just 15 to 20 minutes.

Roasting Process

To begin, preheat your oven to 400°F (204°C) and prepare a baking sheet by lining it with parchment paper or aluminum foil. Wash and dry the tomatoes thoroughly before cutting them in half lengthwise. Arrange the tomato halves cut-side up on the prepared baking sheet. Drizzle them with olive oil and season with salt, pepper, and if desired, a sprinkle of Magic Mushroom Powder for an extra flavor kick.

Place the tomatoes in the oven and roast for about 45 minutes. It’s important to rotate the tray halfway through to ensure even cooking. The tomatoes are perfectly roasted when they have browned slightly at the edges and have shrunk a bit, indicating that their flavors have concentrated.

For an added depth of flavor, include all the liquid from the baking sheet when blending the tomatoes for your soup. This not only prevents waste but also incorporates every bit of the roasted essence into your dish. If you have an abundance of tomatoes, consider roasting a larger batch and freezing them. Simply spread the roasted tomatoes on a baking dish and freeze unsealed until solid, then transfer to a sealed container for long-term storage. This method allows you to enjoy the rich taste of roasted tomatoes year-round in your keto tomato soup.

Cooking the Soup

Sautéing Aromatics

Begin by heating the butter in a large saucepan over medium heat until it melts completely. Add the onions with a pinch of salt, allowing them to cook slowly until they start to caramelize and turn a golden brown. This process should take about 5 minutes. Next, introduce the garlic to the pan, sautéing it until it becomes fragrant and lightly browned, about 30 seconds to 1 minute. This step ensures that the foundation of your keto tomato soup is rich in flavor.

Simmering Soup with Broth

Once the aromatics are ready, add the roasted tomatoes along with any juices that have accumulated from the baking dish. Pour in the chicken broth to cover the vegetables and bring the mixture to a simmer. Reduce the heat to maintain a gentle simmer and cook for about 45 minutes, stirring occasionally. During this time, the flavors will meld together, and the tomatoes will break down, creating a rich, hearty base for your soup. For those preferring a smoother texture, an immersion blender can be used at this stage to blend the soup directly in the pot until it reaches the desired consistency.

Blending and Final Touches

Blending Options

Once the cooking process is complete, the next step is to blend the soup to achieve a smooth consistency. One can either transfer the soup to a blender or use an immersion blender directly in the pot, which is the preferred method for its convenience and ease. If using a traditional blender, it’s essential to blend in batches and keep a hand on the lid to prevent any hot soup from splattering due to steam pressure. For those seeking an ultra-smooth texture, passing the soup through a fine sieve after blending can help remove any remaining solids.

Adding Cream and Cheese

After achieving the desired smoothness, return the soup to the pot. At this stage, add the heavy cream or cream cheese, depending on one’s preference for richness. Heavy cream provides a silky texture, while cream cheese offers a thicker, more velvety consistency. Stir in the cream or cream cheese until fully dissolved. For an enhanced flavor profile, consider adding Parmesan cheese, which should be stirred until melted and combined. Taste the soup and adjust the seasoning with additional salt or pepper as needed. To serve, divide the soup into bowls and garnish with a dollop of cream cheese or fresh herbs for an appealing presentation and added flavor.

Expert Tips for Freezing and Storing

To preserve the delightful flavors of keto tomato soup throughout the year, proper freezing and storing techniques are essential. Here are expert tips to ensure your soup remains fresh and delicious:

Freezing Instructions

1. Roasted Tomatoes: If you have an abundance of tomatoes, consider roasting and freezing them. Store the roasted tomatoes in unsealed pint jars until they are frozen solid, then secure the lids. This method helps maintain their flavor and texture.
2. Soup Storage: For the soup itself, it’s advisable to freeze it without cream. Use glass jars or non-toxic plastic containers, leaving some space at the top as the soup will expand when frozen. Freeze the containers with the lids off initially, and once solid, close them securely. This method prevents any spillage or freezer burn and maintains the soup’s quality for up to 6 months.

Reheating Tips

1. Thawing: Always thaw the frozen soup in the refrigerator overnight before reheating. This gradual thawing helps maintain the texture and flavors of the soup.
2. Reheating: Reheat the soup on the stove over low to medium heat. If the soup was frozen without cream, add it during the reheating process. Stir continuously to avoid any separation of ingredients and ensure even warming. For soups that contain cream and have been frozen, heat slowly while stirring frequently to prevent the cream from curdling.

By following these tips, you can enjoy your keto tomato soup any time of the year, ensuring it tastes as fresh as the day it was made.

Frequently Asked Questions
