Cheddar Cheese Soup
Table of Contents
Introduction
Did you know that a single bowl of restaurant-style cheddar cheese soup can pack over 40 grams of carbs, mostly from flour and potatoes? If you’re following a low-carb or keto lifestyle, that number alone might make you swear off soup for good. The good news is that this cheddar cheese soup recipe cuts the carbs dramatically while keeping every bit of the rich, velvety flavor you crave.
This homemade cheddar cheese soup comes together in under 45 minutes, uses simple pantry staples, and delivers a comforting bowl that fits neatly into a low-carb eating plan.

Ingredients
Here’s everything you need to make this creamy cheddar cheese soup:

- 4 tablespoons butter
- 1/2 cup diced onion
- 2 cloves garlic, minced
- 3 cups chicken broth (low-sodium preferred)
- 1 cup heavy cream
- 3 cups sharp cheddar cheese, freshly shredded
- 1 teaspoon xanthan gum (or a tablespoon of cream cheese, for thickening)
- 1/2 teaspoon smoked paprika
- Salt and black pepper, to taste
- Optional: diced cooked bacon, chopped chives, or a pinch of cayenne for garnish
Substitution tip: If you don’t have heavy cream, full-fat coconut milk works well and keeps this cheddar cheese soup recipe dairy-flexible. For a sharper flavor, swap in aged white cheddar.
Timing
- Prep time: 10 minutes
- Cook time: 25 minutes
- Total time: 35 minutes
That’s roughly 30% faster than most traditional cheddar cheese soup recipes, which often call for simmering a roux-based base for over an hour.
Step-by-Step Instructions
Step 1: Sauté the Aromatics
Melt the butter in a large pot over medium heat. Add the diced onion and cook for 3–4 minutes until softened, then stir in the garlic for another 30 seconds until fragrant.
Step 2: Build the Broth Base
Pour in the chicken broth and bring it to a gentle simmer. This forms the savory foundation of your cheddar cheese soup.
Step 3: Add the Cream and Thickener
Stir in the heavy cream and sprinkle the xanthan gum slowly while whisking constantly to avoid clumping. This keeps the soup thick without any flour or cornstarch.
Step 4: Melt in the Cheese
Reduce the heat to low, then add the shredded cheddar cheese a handful at a time, stirring until fully melted. Adding cheese gradually over low heat is the key trick to a smooth, lump-free cheddar cheese soup.

Step 5: Season and Simmer
Add smoked paprika, salt, and pepper. Let the soup simmer gently for 5 more minutes so the flavors meld together.
Step 6: Serve and Garnish
Ladle into bowls and top with bacon bits, chives, or a dash of cayenne for a flavor boost.

This makes it an excellent fit for keto and low-carb diets. According to the USDA FoodData Central database, cheddar cheese itself carries less than 1 gram of net carbs per ounce, and Healthline notes that cheddar is one of the best cheeses for a keto diet thanks to its high fat, moderate protein, and low carb profile a big contrast to a typical cheddar cheese soup made with flour and potatoes, which can carry 25–30 g of carbs per serving.
Healthier Alternatives for the Recipe
- Lower fat option: Use half-and-half instead of heavy cream to reduce fat while keeping the soup creamy.
- Dairy-free version: Substitute coconut milk and a dairy-free cheddar-style cheese.
- Extra veggies: Stir in steamed broccoli or cauliflower for added fiber without significantly raising the carb count.
- Lower sodium: Use homemade broth or a no-salt-added variety.
Each of these swaps keeps the core of the cheddar cheese soup recipe intact while adapting it to different dietary needs.
Serving Suggestions
This cheddar cheese soup pairs beautifully with:
- A side salad with vinaigrette for a light, balanced meal
- Low-carb crusty bread or almond flour biscuits for dipping

Common Mistakes to Avoid
- Adding cheese too quickly: Dumping in all the cheese at once causes clumping. Add it gradually over low heat.
- Boiling instead of simmering: High heat can cause the cream and cheese to separate. Keep the temperature low once dairy is added.
- Using pre-shredded cheese: Bagged shredded cheese contains anti-caking agents that prevent smooth melting. Shred your own for the best texture.
- Skipping the thickener: Without xanthan gum or a similar low-carb thickener, the soup can turn out thin and watery.
- Over-salting: Cheddar cheese and broth are both naturally salty, so taste before adding extra salt.
Storing Tips for the Recipe
- Refrigerator: Store leftover cheddar cheese soup in an airtight container for up to 4 days.
- Reheating: Warm gently on the stovetop over low heat, stirring frequently to prevent separation. Avoid microwaving on high, which can cause the cheese to break.
- Freezing: This soup is not ideal for freezing since dairy-based soups can separate and become grainy after thawing. If you do freeze it, whisk vigorously while reheating to help re-emulsify.
- Meal prep: Chop the onion and garlic and shred the cheese up to 2 days in advance to save time on cook day.
