Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Fresh or frozen broccoli florets
Butter
Onion, finely chopped
Garlic, minced
Chicken broth or bone broth
Heavy cream
Shredded sharp cheddar cheese
Cream cheese
Salt and pepper
Ground mustard (optional, for added depth)
Paprika or cayenne (optional, for a little heat)

Directions

I start by melting butter in a large pot over medium heat. I add the chopped onion and garlic and sauté until they’re soft and fragrant.
I add the broccoli and pour in the chicken broth, bringing it to a gentle boil. I let it simmer until the broccoli is tender—usually around 10 to 15 minutes.
I reduce the heat to low and stir in the cream cheese until it melts completely.
Then I pour in the heavy cream and let everything heat through, being careful not to let it boil.
I gradually stir in the shredded cheddar cheese, one handful at a time, until the soup is creamy and smooth.
I season with salt, pepper, and optional spices like ground mustard or a pinch of cayenne.
If I want a smoother texture, I blend part of the soup using an immersion blender—but I often leave it chunky for a heartier feel.

Servings and timing

This recipe makes about 4 to 6 servings, depending on bowl size. It takes roughly 25 minutes from start to finish, making it a perfect quick lunch or dinner for busy days.

Variations

For added protein, I stir in shredded rotisserie chicken or leftover grilled chicken.
I use different cheeses like Gruyère or smoked gouda for a fun flavor twist.
To make it spicier, I add a diced jalapeño or a bit more cayenne.
If I want a thicker soup, I reduce the broth slightly or simmer a bit longer uncovered.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 4 days. To reheat, I warm the soup gently on the stove or in the microwave, stirring frequently to keep it smooth. I avoid bringing it to a boil again to prevent the cheese from separating. This soup also freezes well—I portion it out in containers and thaw it in the fridge overnight before reheating.

FAQs

Is this soup really low in carbs?

Yes, it’s very keto-friendly. Broccoli and cheese are both low in carbs, and there are no starchy thickeners used.

Can I use frozen broccoli?

Absolutely. I’ve made it with frozen broccoli many times—it works just as well. I just adjust the cooking time slightly if needed.

How do I prevent the cheese from clumping?

I make sure to lower the heat before adding cheese and stir it in gradually. This keeps it smooth and creamy.

Can I make it dairy-free?

It’s tough to replicate the same creamy texture, but I’ve used full-fat coconut milk and vegan cheese alternatives for a dairy-free version. It’s different, but still tasty.

What’s the best cheese for this soup?

Sharp cheddar melts well and gives a bold flavor, but I’ve also mixed in Monterey Jack, Parmesan, or gouda depending on what I have on hand.

Conclusion

Keto Broccoli Cheese Soup is one of my favorite go-to meals when I want something warm, comforting, and low in carbs. It’s rich, flavorful, and incredibly easy to make with simple ingredients. Whether I’m on a keto plan or just want a hearty bowl of soup, this one always hits the mark.
