Broccoli is the primary ingredient in this Keto Broccoli Cheese Soup. But don’t let the name fool you – this soup is packed with many powerful antioxidant ingredients that will help heal your body from the inside out, including garlic, olive oil, ginger, parsley, and chicken broth. 

What do we know about broccoli? It is packed with vitamins, minerals, and bioactive compounds. It is so perfectly healthy that nutritionists everywhere claim it to be one of the healthiest foods you can eat. 

What do we know in detail? It is an excellent source of vitamin C. It also contains vitamins A, K, and B9, as well as minerals and fiber.

As a cruciferous vegetable, broccoli has been shown to protect against cancer, thanks to its sulforaphane content. Research shows that sulforaphane has anti-inflammatory and chemoprevention properties that control carcinogenesis (*).

Ginger contains the bioactive compound gingerol, which has also been shown to protect against cancer (*). Ginger is also very soothing on upset stomachs, thanks to its antioxidant properties. 

Eating ginger with broccoli is a good way to soothe digestive upset (such as gas) that sometimes accompanies eating cruciferous vegetables. It will help soothe your digestive system while making you feel great. Roasting the broccoli is also a great way to make broccoli more easily digestible.

The combination of olive oil and garlic has been used as holistic medicine for centuries. Garlic contains a compound called allicin that has been shown to contain antioxidant, anti-inflammatory, and lipid-lowering properties. 

Studies have shown that allicin may help prevent cancer, cardiovascular and metabolic disorders, blood pressure, and diabetes (*). 

The healthy fats in the olive oil help make the bioactive compounds in garlic and the rest of this dish more bioavailable. So don’t think of this soup as just food. It’s medicine! 

How to Make Low Carb Cream of Broccoli Soup

Preheat Your Oven: Set your oven to 400°F (200°C) to get it ready for roasting the broccoli.

Prepare Broccoli and Garlic: In a large mixing bowl, combine 3 cups of broccoli florets and 2 peeled garlic cloves. Drizzle them with 1 ½ tablespoons of olive oil and season with sea salt and black pepper. Toss everything together so the broccoli and garlic are evenly coated.

Roast Broccoli and Garlic: Spread the broccoli and garlic evenly on a baking sheet. Put it in the preheated oven and roast for 30 minutes. The goal is to get the broccoli slightly crispy and golden.

Blend Broccoli and Garlic: After roasting, let the broccoli and garlic cool a bit. Then, transfer them to a food processor, add ½ teaspoon of ground ginger, and blend until you get a smooth puree.

Cook the Soup: Pour 4 cups of chicken broth into a large pot and bring it to a boil. Once boiling, reduce the heat to low and add your broccoli puree into the pot. Stir well to combine.

Add Cream: Add ½ cup of heavy cream to the pot. Stir everything together and let it cook on low heat for an additional 2 minutes, just to heat through.

Garnish and Serve: Serve your soup hot. Sprinkle each bowl with freshly chopped parsley, grated Grana Padano cheese, and, if you like, some chopped almonds for an extra crunch.

Does cream of broccoli soup have carbs?

Yes, the typical cream of broccoli soup typically contains much higher carbs, primarily from the broccoli – and sometimes added potatoes or peas as well as any added thickeners or dairy products such as milk. My keto version significantly reduces the carbs by avoiding high-carb ingredients. It has approximately 5 grams of net carbs per serving.

How do you thicken cream of broccoli soup on keto?
To thicken cream of broccoli soup on a keto diet, use low-carb thickeners like xanthan gum, pureed vegetables, heavy cream, cream cheese, or a small amount of coconut or almond flour. Xanthan gum is particularly effective; use it sparingly and whisk continuously to avoid clumps. Pureeing part of the soup itself can also naturally enhance thickness without additional ingredients.

How do you store leftover creamy broccoli soup?

Store leftover creamy broccoli soup in an airtight container in the refrigerator for up to 3-4 days. You can also freeze the soup for longer storage, up to 2-3 months; thaw in the refrigerator before reheating. Reheat gently over low heat to avoid separation.

How do you reheat creamy broccoli soup?

You can reheat creamy broccoli soup by warming it gently over low to medium heat in a saucepan, stirring occasionally to prevent sticking and ensure even heating. Avoid boiling the soup as high heat can cause dairy-based soups to separate or become grainy. If microwaving, use a microwave-safe container and heat in short intervals, stirring in between.
