Keto Creamy Tomato Basil Soup with Parmesan Croutons
"When the temperature drops, nothing warms the soul like a velvety bowl of tomato‑basil bisque, and this keto version delivers all the comfort without the carb overload. By blending fresh tomatoes, fragrant basil, and a splash of heavy cream, you create a silky base that satisfies cravings for a classic comfort food while keeping you firmly in ketosis. The real star of the show is the crunchy parmesan croutons—tiny cheese nuggets toasted to golden perfection, adding a salty crunch that elevates the soup from ordinary to restaurant‑ready. This recipe is perfect for busy weeknights because it comes together in under an hour, uses pantry staples, and yields four hearty servings that each stay under 10 g net carbs. For extra richness, feel free to stir in a dollop of full‑fat cream cheese, and garnish with a drizzle of olive oil and a few fresh basil leaves for a pop of color. Serve it with a simple side salad or a few avocado slices for a complete low‑carb meal that will keep you fueled and satisfied."
Ingredients
Instructions
Heat olive oil in a large pot over medium heat. Add the diced onion and sauté for 2‑3 minutes until translucent.
Stir in the minced garlic and cook for another 30 seconds, being careful not to burn.
Add the chopped tomatoes and cook, stirring occasionally, for 5‑7 minutes until they soften and release their juices.
Pour in the chicken broth and bring the mixture to a gentle boil. Reduce heat and simmer for 10 minutes.
Blend the soup with an immersion blender (or transfer to a countertop blender) until smooth and creamy.
Return the soup to low heat and stir in the heavy cream, cream cheese cubes, salt, and pepper. Simmer for 5 minutes, allowing the cheese to melt and the flavors to meld.
While the soup simmers, preheat the oven to 400°F (200°C). Toss the grated Parmesan with melted butter on a parchment‑lined baking sheet, spreading into a thin layer.
Bake for 5‑7 minutes, watching closely, until the cheese turns golden and crisp. Remove and let cool, then break into bite‑size croutons.
Stir the chopped fresh basil into the soup just before serving. Ladle into bowls, top with Parmesan croutons, and enjoy.
