Ingredients
Method
- Melt the butter: Add butter to a small saucepan over low heat. Let it melt gently without browning.
- Add the cream: Pour in the heavy cream and whisk to combine. Keep the heat on low to medium-low and warm until you see steam, not bubbles.
- Season the base: Whisk in the Dijon, garlic powder, onion powder, and smoked paprika. This builds flavor before the cheese goes in.
- Lower the heat and add cheese: Reduce heat to the lowest setting. Sprinkle in the cheddar and Parmesan gradually, whisking constantly. Let each handful melt fully before adding more.
- Adjust thickness: If the sauce is too thick, whisk in 1 tablespoon of warm water or unsweetened almond milk at a time until smooth and pourable.
- Taste and finish: Season with salt and pepper. Keep the sauce warm on the lowest heat, stirring occasionally, or remove from heat if serving right away.

Ingredients
- 2 tablespoons unsalted butter
- 3/4 cup heavy cream
- 1 cup freshly grated sharp cheddar cheese (about 4 ounces)
- 1/2 cup grated Parmesan cheese (freshly grated for best melt)

Storage Instructions
- Refrigerate: Store in an airtight container for up to 4 days.
- Reheat gently: Warm in a small saucepan over low heat, stirring frequently.
Thin with a splash of water, cream, or almond milk if it’s too thick.
- Freezing: Not ideal. Cheese sauces can separate after thawing. If you must freeze, thaw overnight in the fridge and whisk vigorously while reheating with extra liquid.
Why This is Good for You
- Low in carbs, high in satisfaction: The fat content helps you feel full and keeps cravings in check, which can support a low-carb or keto lifestyle.
- Protein and calcium: Cheese contributes protein and essential minerals like calcium and phosphorus for bone health.
- Minimal additives: Made with whole, familiar ingredients instead of starch-heavy or sugary sauces.
- Customizable for your needs: You can control the sodium, spice level, and richness to fit your goals.
Pitfalls to Watch Out For
- Overheating the sauce: High heat can cause cheese to separate and turn grainy.
Keep it low and slow.
- Pre-shredded cheese: Many bagged cheeses contain anti-caking agents that affect melting. Freshly grate for the smoothest texture.
- Too much salt: Parmesan is salty. Taste before adding extra salt.
- Skipping the whisk: Constant whisking helps the cheese emulsify into the cream for a silky finish.
- Thickness issues: If it’s too thick, add warm liquid a little at a time.
If too thin, let it simmer on very low heat, whisking, until it thickens naturally.
Recipe Variations
- Jalapeño Popper Style: Stir in finely chopped pickled jalapeños and a bit of crumbled bacon. Swap half the cheddar for pepper jack.
- Broccoli Cheddar: Fold in steamed, chopped broccoli. Great for topping chicken or as a side.
- Fondue-Inspired: Replace cheddar with 3/4 cup Gruyère and 1/4 cup Swiss.
Add a splash of dry white wine or apple cider vinegar for brightness.
- Blue Cheese Boost: Add 1/4 cup crumbled blue cheese at the end for a tangy, steakhouse-style sauce.
- Herb and Garlic: Stir in 1 tablespoon finely chopped chives, parsley, or basil. Add a pinch of extra garlic powder if you love garlic.
- Spicy Buffalo: Mix in 1–2 tablespoons buffalo hot sauce and a pinch of cayenne. Great for dips and cauliflower “wings.”
- Dairy Adjustments: For lighter texture, replace 1/4 cup cream with unsweetened almond milk and add 1 ounce cream cheese to keep it silky.
FAQ
Can I use a different cheese?
Yes.
Cheddar, Monterey Jack, pepper jack, Gruyère, Swiss, or a blend work well. Avoid very aged or very dry cheeses on their own, as they can turn grainy. Use at least half a good melting cheese.
How do I fix a grainy or separated sauce?
Remove from heat and whisk in a splash of warm water or cream.
Keep whisking until it comes together. If needed, add a small knob of butter or 1 ounce of cream cheese to re-emulsify.
Is this sauce gluten-free?
Yes. There’s no flour or cornstarch, and the ingredients are naturally gluten-free.
Always check labels on cheese and seasonings just to be safe.
Can I make it without heavy cream?
You can use half heavy cream and half unsweetened almond milk. For extra body, whisk in 1–2 ounces of cream cheese before adding the shredded cheese.
What should I serve it with?
Steamed or roasted broccoli, cauliflower mash, grilled steak or chicken, bunless burgers, zucchini noodles, omelets, and roasted Brussels sprouts are all excellent matches.
How many carbs are in this sauce?
Exact numbers vary by brand, but this sauce is typically very low in carbs, usually around 1–2 net carbs per serving. Check your ingredient labels for the most accurate count.
Can I make it in the microwave?
Yes.
Combine butter and cream in a microwave-safe bowl and heat in short bursts, whisking between each. Add the cheese gradually, whisking until smooth. Keep the power low to avoid overheating.
Why is Dijon mustard in a cheese sauce?
Dijon adds a subtle tang and helps balance the richness.
It won’t make the sauce taste like mustard. You can leave it out, but it adds depth.
How do I keep it smooth for a party?
Keep it warm in a small slow cooker on the “warm” setting. Stir occasionally and add a splash of warm liquid if it starts to thicken too much.
In Conclusion
Keto cheese sauce is a simple, reliable way to make everyday meals more satisfying.
With just a few pantry staples and low heat, you’ll have a smooth, restaurant-quality sauce in minutes. Keep the technique gentle, grate your own cheese, and season to taste. Once you nail the basics, you can spin it into endless variations and pair it with almost anything.
It’s the kind of kitchen staple that earns a permanent spot in your weekly rotation.
