Ingredients Needed
- Fresh Tomatoes – 6 large, ripe tomatoes (or use canned, but fresh is best for flavor).
- Butter – 3 tablespoons (or you can use heavy cream for an even richer taste).
- Olive Oil – 2 tablespoons (extra virgin works wonders for depth of flavor).
- Onion – 1 medium-sized yellow onion, finely chopped.
- Garlic – 3 cloves, minced (or more if you love garlic).
- Vegetable or Chicken Broth – 3 cups (make sure it’s low-sodium and free of added sugars).
- Heavy Cream – 1 cup (adds creaminess without the carbs).
-
Herbs & Spices
- 1 teaspoon dried basil
- 1 teaspoon dried oregano
- Salt and pepper to taste
- A pinch of red pepper flakes – Optional, for a hint of spice.
- Parmesan Cheese – 1/4 cup grated (optional, for garnish).
Cooking Instructions
- Prep the tomatoes: If you’re using fresh tomatoes, score the tops with an “X” and blanch them in boiling water for about 30 seconds. Transfer to an ice bath and peel off the skins. Once peeled, chop them into small chunks. If using canned tomatoes, skip this step and simply chop them up if needed.
- Sauté the aromatics: In a large pot, melt the butter and olive oil over medium heat. Add the chopped onions and cook until translucent (about 4-5 minutes). Add the garlic and cook for another 1-2 minutes, stirring frequently to prevent burning.
- Simmer the soup base: Add the tomatoes to the pot, stirring them into the onions and garlic. Let them cook down for about 5 minutes to release their juices.
- Add the broth and spices: Pour in the vegetable or chicken broth and stir in the dried basil, oregano, salt, and pepper. Bring the soup to a simmer and cook for 15-20 minutes, allowing the flavors to meld together.
- Blend the soup: Once the soup has simmered, use an immersion blender to blend it until smooth. If you don’t have an immersion blender, carefully transfer the soup in batches to a blender. Be sure to let it cool a bit before blending.
- Finish with cream: Once the soup is smooth, stir in the heavy cream and let it heat through for another 3-5 minutes.
- Serve and garnish: Pour into bowls, and if desired, top with grated Parmesan cheese and a sprinkle of red pepper flakes for some extra flavor.
Ingredient Insights
Understanding the ingredients that make up this keto-friendly tomato soup is essential for appreciating its flavor profile and health benefits:
- Tomatoes: Tomatoes are naturally low in carbs, especially when compared to other fruits, and are a rich source of antioxidants like lycopene, which supports heart health. Fresh tomatoes tend to have a more vibrant flavor, but canned tomatoes are a great substitute and can be even more convenient.
- Butter and Olive Oil: These two fats not only add richness and flavor but also supply the necessary healthy fats that keep you full and satisfied. Olive oil, in particular, is packed with monounsaturated fats, which have been linked to reduced inflammation and heart health.
- Heavy Cream: The heavy cream contributes to the soup’s rich, velvety texture while keeping the carb count low. It’s a keto favorite, as it adds delicious creaminess without raising blood sugar levels.
- Herbs and Spices: Basil, oregano, and garlic are keto-friendly flavor-boosters that add complexity to the soup. Garlic has powerful antioxidant properties and may help lower blood pressure, while basil and oregano provide an aromatic punch that elevates the dish.
Expert Tips
- Adjust the consistency: If you prefer a thicker soup, add less broth. If you like it more on the watery side, add extra broth. Just be sure to taste as you go to ensure the flavors stay balanced.
- Add some protein: For a heartier meal, you can add cooked chicken, bacon, or ground turkey. This will elevate your soup, making it a complete meal while keeping things keto-friendly.
- Roast your tomatoes: For an even richer tomato flavor, consider roasting the tomatoes with olive oil, salt, pepper, and herbs before adding them to the soup. Roasting caramelizes the tomatoes, bringing out their natural sweetness and depth of flavor.
- Blending the soup: If you don’t have an immersion blender, you can also use a regular blender. Just be cautious when blending hot liquids to avoid spills or burns.
Recipe Variations
- Spicy Keto Tomato Soup: Add a dash of cayenne pepper or a few fresh chopped jalapeños for some heat. This adds a fun layer of flavor without adding carbs.
- Creamy Tomato Basil: Stir in fresh chopped basil just before serving for a fresh, herbal twist.
- Keto Tomato Soup with Mozzarella: Top the soup with a handful of shredded mozzarella cheese, letting it melt into the soup for an extra cheesy goodness.
- Roasted Garlic Tomato Soup: For an even deeper flavor, roast the garlic alongside the tomatoes in the oven before adding it to the pot. It will mellow the garlic’s sharpness and bring out a richer flavor profile.
Final Words
Keto Tomato Soup is the perfect combination of comforting, rich, and healthy. Whether you’re sticking to a strict low-carb diet or just looking to enjoy a satisfying meal, this recipe is a great way to satisfy your cravings without the carbs. The creamy texture, the depth of the tomato flavor, and the aromatic herbs make it a dish you’ll want to come back to again and again. Plus, it’s easy to make, requiring only a handful of ingredients.
This soup is also incredibly versatile. It can be eaten on its own as a meal or paired with keto-friendly sides like cauliflower bread or a simple green salad. You can even use it as a base for other low-carb creations, like a creamy casserole.
