What Makes This Recipe Awesome
- Ultra-creamy texture without flour: We use cream, cheese, and a smart simmer to get that luxurious body—no roux required.
- Ridiculously fast: From fridge to bowl in about 20–25 minutes. The real bottleneck is grating the cheese—so buy pre-shredded if you must.
- Low-carb, high-satiety: Broccoli brings fiber. Cheese and cream bring fat.
Your hunger doesn’t stand a chance.
- Flexible AF: Add bacon, swap cheeses, throw in some roasted garlic—this soup plays well with almost anything savory.
- Beginner-friendly: No fancy techniques. Just sauté, simmer, blend, and gloat.
Ingredients
- 2 tbsp butter (or ghee for a nutty note)
- 1 tbsp olive oil (optional, for extra richness)
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 4 cups broccoli florets (fresh or frozen)
- 3 cups low-sodium chicken broth (or vegetable broth)
- 1 cup heavy cream
- 2 cups shredded sharp cheddar cheese (freshly grated for best melt)
- 1/2 cup grated Parmesan (adds salty umami depth)
- 1/2 tsp mustard powder (or 1 tsp Dijon)
- 1/4 tsp smoked paprika (optional but recommended)
- Pinch of nutmeg (classic with creamy soups)
- Salt and black pepper to taste
- Optional toppings: crispy bacon bits, chives, red pepper flakes, extra cheese
Instructions
- Sauté the aromatics: In a heavy pot over medium heat, melt butter with olive oil. Add onion with a pinch of salt and cook 3–4 minutes until translucent.
Stir in garlic for 30 seconds until fragrant.
- Add broccoli and broth: Toss in broccoli, mustard powder, smoked paprika, and nutmeg. Pour in chicken broth. Bring to a simmer and cook 8–10 minutes until broccoli is tender but still bright.
- Blend to your preferred texture: Use an immersion blender for a rustic, slightly chunky soup, or blend in batches for ultra-smooth.
Leave some florets whole if you like a bit of bite.
- Add cream: Return soup to low heat. Stir in heavy cream. Do not boil—gentle heat keeps everything silky.
- Melt the cheeses: Reduce heat to low.
Gradually add cheddar and Parmesan by the handful, stirring constantly until melted and smooth. If it starts to look stringy, you’re too hot; remove from heat and keep whisking.
- Season like you mean it: Taste, then add salt and pepper. Adjust with more paprika or a squeeze of lemon if you want brightness.
- Finish and serve: Ladle into bowls and top with crispy bacon, chives, or extra cheese.

Storage Tips
- Fridge: Store in an airtight container for 3–4 days. Reheat gently over low heat, stirring often. Avoid boiling to prevent cheese separation.
- Freezer: It freezes fine for up to 2 months, but texture may loosen slightly.
Cool completely, portion, and freeze. Thaw overnight in the fridge and whisk while reheating.
- Meal prep hack: Freeze in single-serve portions. Add fresh toppings (bacon, chives) right before serving so they stay crisp.
Why This is Good for You
- Low-carb, high-fat balance: Keeps you in ketosis while delivering serious satiety.
No 3 p.m. snack attacks.
- Broccoli brings the goods: Fiber, vitamin C, vitamin K, and antioxidants. Your body will thank you even if your inner five-year-old protests.
- Protein + fat combo: The cheese contributes protein, while cream and butter deliver fats that help stabilize energy and support hormone health (IMO, underrated).
- No blood sugar rollercoaster: Minimal carbs means steady energy and clear focus. It’s like noise-canceling for hunger.
Don't Make These Errors
- Boiling after adding cheese: High heat can cause separation and graininess.
Keep it low and slow during the melt stage.
- Pre-shredded cheese overload: It often has anti-caking agents that don’t melt as smoothly. Freshly grated cheddar is your best friend.
- Under-salting: Broth and cheese vary. Taste at the end and season properly.
Bland soup is a crime.
- Skipping the aromatics: Onion and garlic are flavor multipliers. Don’t trade them for “speed.” You’ll notice.
- Using too much water: Broth adds flavor. If you must thin, do it gradually.
You can’t un-water a soup.
Different Ways to Make This
- Roasted Broccoli Version: Roast florets at 425°F (220°C) with olive oil and salt for 15–20 minutes. Add to the blended base for smoky depth and charred edges.
- Bacon Lovers: Cook chopped bacon first, remove it, and sauté onion in the rendered fat. Crumble bacon on top to finish.
Flavor jackpot.
- Triple Cheese: Mix cheddar, Gruyère, and a bit of cream cheese for extra silkiness. Adjust salt—Gruyère can be assertive.
- Spicy Kick: Add 1–2 tsp hot sauce or 1/2 tsp red pepper flakes with the broth. It wakes things up, fast.
- Vegetarian Swap: Use vegetable broth and a rennet-free cheese.
Consider a pinch of white miso for extra umami.
- Extra Protein: Stir in diced rotisserie chicken at the end. Heat through without boiling.
- Dairy-Light Option: Sub part of the cream with full-fat coconut milk. Flavor changes slightly, but it’s still rich and keto-friendly.
FAQ
Can I use frozen broccoli?
Yes.
Toss it in straight from the freezer and simmer a couple of extra minutes. It blends beautifully and still tastes fresh if you season well.
What cheeses melt best for this soup?
Sharp cheddar is classic. Add Parmesan for depth and a little cream cheese for extra smoothness.
Avoid super-aged cheeses that get oily when heated.
How do I fix a grainy soup?
Take the pot off heat and whisk vigorously. If needed, blend briefly. Next time, lower the heat before adding cheese and add it gradually.
Is this soup actually keto?
Absolutely.
It’s low in net carbs and high in fat. Check your specific ingredients, but most versions clock in at roughly 4–7g net carbs per serving, FYI.
Can I make it without cream?
You can use half-and-half or unsweetened almond milk, but it won’t be as rich. A spoonful of cream cheese can help restore body.
How do I thin or thicken the soup?
To thin, add warm broth a little at a time.
To thicken, simmer uncovered for a few minutes or melt in an extra ounce of cream cheese.
What if I don’t have an immersion blender?
Use a regular blender in batches. Vent the lid slightly and cover with a towel to avoid steam explosions—because nobody wants a cheddar facial.
