Ingredients (Serves 4)

• 4 cups broccoli florets (fresh or frozen)
• 2 cups chicken broth (low sodium recommended)
• 1 cup heavy cream
• 2 cups shredded cheddar cheese (sharp or medium)
• ½ cup cream cheese
• 2 garlic cloves, minced
• ½ tsp onion powder

Tip: For best results, use freshly grated cheddar—it melts smoother than pre-shredded varieties.

How to Make Keto Creamy Broccoli Cheddar Soup

1. Simmer the Broccoli

In a large pot, combine:

• Broccoli florets
• Chicken broth
• Garlic
• Onion powder

Bring everything to a boil over medium-high heat. Then reduce the heat and let it simmer for 8–10 minutes, or until the broccoli is very tender.

2. Blend to Your Liking

Once the broccoli is cooked, use an immersion blender directly in the pot to puree the soup to your desired texture.

Want it silky-smooth? Blend completely. Prefer a chunky texture with bites of broccoli? Just pulse it a few times.

No immersion blender? Transfer the soup carefully to a countertop blender and blend in batches. Just be cautious with the hot liquid.

3. Stir in the Creamy Goodness

Add:

• Heavy cream
• Cream cheese
• Cheddar cheese

Stir over low heat until the cheeses are fully melted and the soup is thick and creamy. This step gives the soup its signature richness and a velvety finish.

4. Season and Serve

Taste and season with salt and pepper as needed. Spoon into bowls and serve warm.

Top with extra shredded cheese, a dash of paprika, or crispy bacon crumbles if you’re feeling indulgent.

Variations and Add-Ins

This Keto Creamy Broccoli Cheddar Soup is incredibly versatile. Try adding:

Crumbled bacon: For a smoky crunch
Shredded rotisserie chicken: To turn it into a full meal
Cauliflower: Add half broccoli, half cauliflower for a veggie blend
Spice it up: A pinch of cayenne or chili flakes
More veg: Wilted spinach, chopped kale, or sautéed mushrooms

What to Serve With This Keto Soup

• Keto garlic bread or low-carb rolls
• Chopped salad with lemon vinaigrette
• Parmesan crisps for dipping
• Grilled sausage or chicken for a protein boost

Tips for Success

• Simmer gently—don’t boil the cream once it’s added to avoid curdling
• Use sharp cheddar for bold flavor
• Adjust the thickness—add more broth if too thick or simmer longer to reduce
• Reheat gently on the stovetop or microwave in short bursts

Storage & Reheating

Refrigerator: Store in an airtight container for up to 4 days
Freezer: Freeze in portions for up to 2 months. Thaw overnight in the fridge before reheating
Reheating: Warm gently over low heat, stirring often. Add a splash of broth if needed to loosen
