Why Keto Broccoli Cheese Soup Is the Perfect Low-Carb Comfort Food
What Makes Broccoli Cheese Soup a Keto Favorite
Keto isn’t just about bacon and butter—it’s about balance. That’s where keto broccoli cheese soup fits perfectly. Broccoli is one of the most keto-compatible vegetables, loaded with fiber and vitamins but light on carbs. Combine that with full-fat cheese and cream, and you’ve got a luxurious comfort food that aligns with your keto macros.
This soup delivers big flavor while keeping net carbs in check, making it ideal for lunch, dinner, or even batch prep for the week. Plus, it’s family-friendly and satisfying enough for even non-keto eaters.
Nutritional Benefits of Keto Ingredients Like Broccoli and Cheese
Let’s break it down:
- Broccoli provides fiber, vitamin C, and antioxidants—all while clocking in at only 4g of net carbs per cup.
- Cheddar cheese brings protein and healthy fats, helping you hit your keto targets while staying full longer.
- Heavy cream and butter add a silky texture and high-fat content, essential for staying in ketosis.
Here’s a quick look at the nutrition profile of typical homemade keto broccoli cheese soup:
Ingredient | Net Carbs (per serving) | Fat | Protein |
---|---|---|---|
Broccoli (1 cup) | 4g | 0g | 3g |
Cheddar Cheese (1/2 cup) | 1g | 9g | 7g |
Heavy Cream (2 tbsp) | <1g | 11g | 0g |
Not only is this soup rich and satisfying, but it also checks all the boxes for a keto-approved meal—low in carbs, high in fat, and nourishing.
Ingredients for Keto Broccoli Cheese Soup

Best Keto-Friendly Cheese Options for Soup
Cheese isn’t just a flavor booster in keto broccoli cheese soup—it’s also a nutritional workhorse. Choosing the right cheese helps you maintain ketosis and build creaminess without unwanted carbs.
Here are the top cheese options:
- Sharp Cheddar: The classic choice. Melts smoothly and brings bold flavor with just 1g of carbs per ounce.
- Cream Cheese: Adds rich texture and helps thicken the soup. Choose full-fat versions with <1g net carbs per serving.
- Parmesan: A salty, umami-rich topping that deepens the flavor. Contains nearly zero carbs.
- Gruyère or Swiss: Great for a nutty twist if you want to change things up.
Always check the nutrition label—some pre-shredded cheeses contain anti-caking agents that can sneak in extra carbs.
Broccoli: A Crucial Low-Carb Vegetable in Keto Diets
Broccoli is one of the most keto-friendly vegetables, and it’s not just for texture—it’s loaded with fiber, vitamins, and antioxidants.
Let’s break down why broccoli deserves the spotlight:
- Low in net carbs: About 4g per cup after subtracting fiber.
- High in fiber: Helps with digestion and staying full.
- Rich in micronutrients: Like vitamin C, calcium, and folate.
For soup, use either fresh or frozen broccoli florets. Just avoid pre-mixed frozen blends with added sugars or sauces.
You can even blend part of the broccoli into the soup base to make it thicker and creamier without adding flour or starch.
Hidden Carbs in Soup Ingredients to Avoid
Even in homemade recipes, carbs can sneak in. Here’s what to avoid when building your keto broccoli cheese soup:
- Flour, cornstarch, or roux: Traditional thickeners loaded with carbs.
- Milk: Especially low-fat varieties. Use heavy cream or unsweetened almond milk instead.
- Processed cheese products: Think cheese sauces or dips—they often include starches and sugars.
- Pre-made broths: Check for added sugar or dextrose. Go for bone broth or keto-certified brands.

Cooking Instructions and Simmering Techniques
Here’s the ultimate keto-approved way to make broccoli cheese soup that’s smooth, rich, and low-carb:
Ingredients (Serves 4–6)
Ingredient | Quantity |
---|---|
Broccoli florets (fresh or frozen) | 4 cups |
Sharp cheddar cheese, shredded | 2 cups |
Cream cheese | 4 oz |
Heavy cream | 1 cup |
Chicken or bone broth (low-carb) | 3 cups |
Butter | 2 tbsp |
Onion, finely chopped (optional) | ¼ cup |
Garlic, minced | 2 cloves |
Salt and pepper | To taste |
Xanthan gum (optional, for thickening) | ½ tsp |
Instructions
- Sauté Aromatics
In a large soup pot, melt butter over medium heat. Add chopped onions and garlic. Cook until soft and fragrant (about 3–4 minutes). - Add Broccoli and Broth
Stir in broccoli florets and pour in the broth. Cover and simmer for 10–15 minutes until the broccoli is very tender. - Blend the Base
Use an immersion blender to partially blend the soup. Leave some chunks for texture, or blend it completely smooth—your choice. - Add Dairy and Melt the Cheese
Reduce the heat to low. Stir in cream cheese until fully melted, then add heavy cream and shredded cheddar. Stir constantly until cheese is melted and soup is smooth. - Adjust Thickness (Optional)
For a thicker soup, sprinkle in xanthan gum and stir well. Let simmer for 2–3 minutes until it thickens. - Season and Serve
Add salt and pepper to taste. Serve hot, garnished with extra cheese, a dollop of sour cream, or crispy bacon bits if desired.

Keto Store-Bought Options — Are They Truly Keto?
Is Campbell’s Broccoli Cheese Soup Keto Friendly?
Short answer: Not really.
While it sounds like a good fit, Campbell’s Broccoli Cheese Soup doesn’t qualify as a true keto broccoli cheese soup. The condensed version may look similar but contains hidden carbs from starches and added sugars that make it a poor choice for a ketogenic diet.
Here’s a breakdown of one ½-cup serving:
Nutrient | Amount |
---|---|
Total Carbs | 12g |
Sugar | 3g |
Protein | 2g |
Fat | 6g |
These numbers may not seem outrageous, but if you’re sticking to a daily carb limit, even one bowl could kick you out of ketosis. The presence of cornstarch, food starch, and sugar disqualifies this soup from the keto-friendly list.
If you’re craving a safe, filling option, you’re better off preparing a homemade keto broccoli cheese soup where you control every ingredient—no thickeners, no added sugars, just clean keto-friendly comfort food.
Best Store-Bought Brands vs Homemade Version
Some brands market their soups as low-carb, but they still don’t compare to a homemade keto broccoli cheese soup in terms of freshness, fat content, or carb control.
Brand | Net Carbs | Keto-Friendly? | Notes |
---|---|---|---|
Campbell’s | 12g | ❌ No | High in starch and sugar |
Kettle & Fire | 4g | ✅ Yes | Uses bone broth and clean fats |
Proper Good | 5g | ✅ Yes | Shelf-stable, clean label |
Homemade | 4–5g | ✅ Yes | Ultimate control and flavor |
A bowl of freshly made keto broccoli cheese soup gives you all the creamy comfort you want without compromising your low-carb lifestyle.

FAQ
Can I eat broccoli cheese soup on keto?
Yes, you absolutely can—as long as it’s made with keto-friendly ingredients. Traditional recipes often include flour or starchy thickeners, which are high in carbs. However, keto broccoli cheese soup uses low-carb vegetables like broccoli, full-fat dairy like heavy cream and cheese, and no flour. It’s a perfect keto-compliant comfort food when prepared correctly.
How many carbs are in cheesy broccoli soup?
That depends on the ingredients. A typical homemade keto broccoli cheese soup has around 4 to 6 grams of net carbs per serving, while store-bought versions can contain 15 to 20 grams or more, mostly due to added thickeners and starches. Always check nutrition labels or make it at home to keep your carb intake in check.
Is Campbell’s broccoli cheese soup keto friendly?
Not really. Campbell’s Broccoli Cheese Soup contains modified food starch, wheat flour, and other high-carb additives, making it unsuitable for a strict keto diet. One serving can have over 15g of net carbs, which may use up your entire carb limit for the day. It’s better to make your own version at home using keto-friendly ingredients.
Are broccoli and cheese considered keto?
Yes, both are keto-approved! Broccoli is a low-carb, high-fiber vegetable, rich in vitamins and antioxidants. Cheese, especially full-fat varieties like cheddar or cream cheese, is high in fat and low in carbs—ideal for keto. Together, they make a delicious and nutritious combo for any low-carb meal.
Conclusion
Keto broccoli cheese soup is the kind of meal that proves you don’t have to sacrifice comfort food when eating low carb. Rich, creamy, and full of nutrients, this soup is not only satisfying but also easy to prepare and customize. Whether you’re trying to lose weight, manage blood sugar, or just enjoy a healthy meal, this recipe belongs in your kitchen rotation.
