Creamy Low-Carb Mac and Cheese: The Ultimate Cauliflower & Shirataki Guide
Low-carb mac and cheese has become my absolute obsession since ditching traditional pasta three years ago.
Let me guess – you’re staring at another sad, mushy cauliflower disaster thinking “this will never taste like real mac and cheese.”
I get it.
I’ve been there.
I’ve made every mistake in the book.
But here’s what I’ve learned: the secret isn’t trying to replicate traditional mac and cheese.
It’s about creating something even better.
KEY INFO

Total time: 40 minutes
Servings: 6 generous portions
Difficulty level: Easy
Dietary tags: Keto, low-carb, gluten-free, vegetarian
Cost: Moderate ($$)
Net carbs: Less than 8g per serving
EQUIPMENT NEEDED
Essential tools:
- Large pot for boiling
- Heavy-bottomed saucepan
- 9×13 inch baking dish
- Fine mesh colander
- Whisk
Simple alternatives:
- Use a microwave-safe bowl instead of boiling pot
- Any medium saucepan works (just watch the heat)
- Individual ramekins instead of large dish
INGREDIENTS
Base (choose one):
- 2 large heads cauliflower, cut into florets (8 cups) OR
- 1 lb low-carb pasta (I prefer Palmini or Great Low Carb Bakery) OR
- 2 bags (8 oz each) shirataki noodles, thoroughly rinsed
The Cheese Sauce:
- 1¼ cups heavy cream
- 8 oz cream cheese, softened
- 3 cups sharp cheddar cheese, freshly grated (pre-shredded makes it grainy)
- ½ cup Parmesan cheese, grated
- 2 cloves garlic, minced
- 1 tsp Dijon mustard
- ½ tsp smoked paprika
- Salt and black pepper to taste
Optional Toppings:
- ½ cup pork rind crumbs (for crunch)
- Extra cheddar for broiling
- Fresh chives, chopped
METHOD
Prep Your Base
1. If using cauliflower: Boil florets in salted water for 8-10 minutes until just fork-tender.
Don’t overcook – mushy cauliflower ruins everything.
2. If using shirataki noodles: Rinse under cold water for 2 minutes, then boil for 3 minutes.
This removes that weird smell everyone complains about.
3. If using low-carb pasta: Follow package directions but cook 1 minute less than recommended.
4. Drain everything thoroughly and pat dry with paper towels.
This step is crucial – excess water makes watery mac and cheese.
Create the Magic Sauce
5. Preheat your oven to 375°F.
6. In your heavy saucepan, warm the cream over medium-low heat.
Don’t let it boil.
7. Whisk in the cream cheese until completely smooth.
No lumps allowed here.
8. Add garlic, mustard, and paprika.
Whisk for 30 seconds until fragrant.
9. Remove from heat – this is important.
Add cheddar cheese in three batches, whisking constantly.
The residual heat melts it perfectly without breaking the sauce.
10. Stir in Parmesan and season with salt and pepper.
Taste and adjust – this should be boldly flavored.
Bring It Together
11. Fold your prepared base into the cheese sauce.
Mix gently but thoroughly.
12. Transfer to your baking dish and sprinkle with extra cheese.
13. Bake for 20-25 minutes until bubbling and golden on top.
14. Optional: Switch to broil for 2-3 minutes for extra browning.
Watch it like a hawk – it goes from perfect to burnt in seconds.
15. Rest for 10 minutes before serving.
I know it’s torture, but this lets everything set properly.
CRUCIAL TIPS
For perfect texture:
- Never boil the sauce once cheese is added – it will break
- Pat everything bone dry after cooking
- Use freshly grated cheese – it melts so much better
- Don’t skip the resting time
Flavor boosters:
- Add a splash of hot sauce to the cheese mixture
- Mix in cooked bacon or ham
- Try different cheese combinations (Gruyère is incredible)
Storage & Scaling
Storage: Refrigerate covered for up to 4 days.
The cauliflower version holds better than noodle versions.
Reheating: Oven at 350°F for 15-20 minutes, covered.
Add a splash of cream if it looks dry.
Scaling: Double everything for crowds, use two dishes.
Half the recipe works perfectly for smaller portions.
Common Mistakes to Avoid
The big ones I see constantly:
- Overcooking the base (especially cauliflower)
- Using pre-shredded cheese
- Not draining properly
- Boiling the cheese sauce
With shirataki specifically:
- Not rinsing long enough
- Skipping the boiling step
- Expecting pasta-like texture (adjust expectations)
Variations That Actually Work
- Loaded mac: Add crispy bacon, jalapeños, and scallions
- Veggie-packed: Mix in roasted broccoli or spinach
- Spicy version: Use pepper jack cheese and add hot sauce
- Protein boost: Stir in rotisserie chicken or ground beef
The beauty of this low-carb mac and cheese recipe is its flexibility.
I’ve served this to die-hard pasta lovers who had no idea they were eating cauliflower.
The secret is that bold, creamy cheese sauce that coats every bite.
My kids request this over the boxed stuff now.
That’s when you know you’ve cracked the code.
Start with the basic recipe, then make it your own.
Your taste buds (and your waistline) will thank you.
