Keto Tuscan Soup

Keto Tuscan Soup is a rich and creamy low—carb take on the classic Tuscan—style soup. It combines tender chicken, fresh spinach, and a savory creamy broth to create a hearty meal that fits perfectly into any keto lifestyle. This comforting dish is quick to prepare and delivers deep, satisfying flavors with every spoonful.

I remember making this during a chilly evening when I craved something warm and filling. Now it's become a favorite that my friends ask for whenever they visit.

Ingredients

• Olive oil: Olive oil ensures a good cooking base and adds healthy fats—choose extra virgin for the best flavor
• Chicken: Boneless, skinless chicken breasts or thighs provide lean protein—thighs add extra moisture if you prefer
• Onion: Small onion adds sweetness and depth—look for firm onions without soft spots
• Garlic: Garlic cloves bring aromatic warmth—fresh minced garlic is always best for that punch
• Chicken broth: Chicken broth forms the flavorful liquid base—homemade or low sodium store—bought makes the soup richer
• Canned diced tomatoes: Canned diced tomatoes give a subtle acidity and texture—drain well to avoid excess liquid
• Dried basil and oregano: Dried basil and oregano contribute classic Italian herb flavors—always opt for fresh or recently opened dried herbs
• Red pepper flakes: Red pepper flakes add a gentle heat if you want a little kick, but it’s optional
• Fresh spinach: Fresh spinach packed with nutrients and vibrant color—choose crisp leaves and wash thoroughly
• Heavy cream: Heavy cream lends creaminess and richness—full fat works best for keto diets
• Parmesan cheese: Grated Parmesan cheese enriches the texture and adds umami—freshly grated elevates the soup even more
• Salt and pepper: Salt and pepper for seasoning to balance the flavors perfectly
• Fresh herbs: Fresh parsley or basil for garnish brings a fresh herbal note and visual appeal

Instructions

Sear the Chicken:

Heat olive oil in a large pot over medium heat. Add the diced chicken to the hot oil and cook until golden brown on all sides, about five to seven minutes. This browning develops flavor and seals in juices. Remove the chicken and set aside.

Cook the Onion:

In the same pot, stir in the diced onion. Let it cook for two to three minutes until it becomes translucent and soft. This gentle cooking releases the onion’s natural sweetness and builds the base flavor.

Add Garlic:

Add the minced garlic and cook for another one to two minutes until fragrant. Be careful not to brown the garlic or it will become bitter.

Build the Broth:

Pour in the chicken broth and add the drained diced tomatoes. Sprinkle in the dried basil, oregano, and if using, the red pepper flakes. Bring the mixture to a gentle simmer, which helps meld the flavors.

Simmer with Chicken:

Return the cooked chicken to the pot. Let the soup simmer gently for about ten minutes to allow the chicken to absorb the herb—infused broth.

Add Spinach:

Stir in the chopped fresh spinach. Cook for two to three minutes until wilted and vibrant green, adding freshness and nutrients.

Finish with Cream and Cheese:

Lower the heat and slowly stir in the heavy cream followed by the grated Parmesan cheese. Stir constantly until the cheese melts completely and the soup turns creamy and luscious. Season with salt and pepper to taste.

Serve and Garnish:

Ladle the hot soup into bowls and garnish with fresh parsley or basil if you like. Serve immediately for the best flavor.

I have always loved the way the Parmesan cheese melts into the creamy broth, turning a simple soup into a decadent treat. One family night, this soup was the star when everyone needed something warm and satisfying after a long day.

Storage tips

Store leftovers in an airtight container in the refrigerator and consume within three days. Reheat gently on low heat to avoid curdling the cream. This soup does not freeze well because dairy tends to separate when thawed, so enjoy fresh if possible.

Ingredient substitutions

You can swap chicken for Italian sausage or turkey for some variety. Use coconut cream instead of heavy cream for a dairy—free keto option. If you want it thicker, blend a portion of the soup before adding cream and cheese, or reduce the broth slightly.

Serving suggestions

Pair this soup with a simple side salad or some roasted low—carb vegetables like zucchini ribbons or cauliflower. A sprinkle of extra Parmesan or a drizzle of good olive oil on top enhances the richness even further.

This soup is a cozy low—carb meal that still feels indulgent. Adjust herbs and proteins to make it your own.
