Ingredients for Keto Broccoli Cheese Soup

This soup uses simple, keto-friendly ingredients that you likely already have in your pantry. Here’s everything you’ll need:

4 cups fresh broccoli florets (about 1 medium-sized head of broccoli)
2 tablespoons unsalted butter (for sautéing)
1 small onion (diced)
2 cloves garlic (minced)
4 cups chicken broth (preferably low-sodium)
1 ½ cups heavy cream (for creaminess)
2 cups shredded sharp cheddar cheese (use good-quality cheese for the best flavor)
1 cup shredded mozzarella cheese (for extra creaminess and stretch)
Salt and pepper (to taste)
1 teaspoon Dijon mustard (adds depth of flavor)
½ teaspoon garlic powder (optional, for extra flavor)
½ teaspoon onion powder (optional, for extra flavor)
Chopped fresh parsley (for garnish, optional)

Step-by-Step Instructions

Now that you’ve got your ingredients, let’s dive into the easy step-by-step process of making this Keto Broccoli Cheese Soup.

Step 1: Sauté the Aromatics

Heat the butter in a large pot over medium heat. Once the butter is melted, add the diced onion and sauté for about 3-4 minutes, until it becomes soft and translucent.
Cook for a further 30 seconds, or until aromatic, after adding the minced garlic. Be careful not to burn the garlic.

Step 2: Cook the Broccoli

Add the broccoli florets to the pot and stir them into the onions and garlic. Sauté for 3-4 minutes, allowing the broccoli to absorb the flavors.
After adding the chicken broth, boil the mixture. Reduce the heat and let it cook for about 8-10 minutes, or until the broccoli is tender and can be easily pierced with a fork.

Step 3: Add the Cream and Seasonings

Once the broccoli is tender, add the heavy cream to the pot, stirring to combine. Allow the flavours to combine by simmering the soup for a further three to four minutes.
Stir in the Dijon mustard, garlic powder, onion powder, salt, and pepper to taste. To suit your tastes, adjust the seasoning as necessary.

Step 4: Add the Cheese

Slowly add the shredded cheddar cheese and mozzarella cheese to the soup, stirring constantly until the cheese melts into the broth, creating a creamy, cheesy texture. You want the soup to be thick and smooth, so take your time with this step.

Step 5: Blend the Soup (Optional)

If you prefer a smoother, creamier texture, you can use an immersion blender to puree part of the soup, leaving some chunks of broccoli for texture. Alternatively, you can blend a portion of the soup in a regular blender and then return it to the pot.
Be careful when blending hot liquids—make sure to let the soup cool slightly before transferring it to a blender, or use an immersion blender directly in the pot.

Step 6: Serve & Garnish

Once your soup is smooth, creamy, and perfectly cheesy, ladle it into bowls.
Garnish with a sprinkle of chopped parsley for a touch of freshness, and maybe an extra handful of shredded cheese if you're a cheese lover (I know I am!).

Serve hot and enjoy your creamy, comforting Keto Broccoli Cheese Soup!

The Greatest Keto Broccoli Cheese Soup Recipes.

Use Fresh Broccoli: Fresh broccoli gives the best texture and flavor, but if you’re in a pinch, frozen broccoli works too. Just be sure to thaw and drain it thoroughly to avoid excess water in the soup.
Add More Veggies: If you want to add more low-carb veggies to your soup, consider adding zucchini, spinach, or cauliflower. Just remember to modify the cooking time as necessary.
Extra Creaminess: For an even creamier texture, you can add a few tablespoons of cream cheese or mascarpone cheese to the soup when adding the heavy cream.
Customize the Cheese: While sharp cheddar is the classic choice, you can experiment with different cheeses. Try adding Gruyère, Parmesan, or Monterey Jack for variations in flavor and texture.
Make it Spicy: Add a pinch of cayenne pepper or red pepper flakes to spice up the soup and add some extra warmth.
