What You’ll Need
Ingredients
| Ingredient | Amount | Notes |
|---|---|---|
| Garlic | 1 whole head | Roasted (trust me, don’t skip) |
| Parmesan cheese | 1 cup, finely grated | Go fresh, not the shaker stuff |
| Mayonnaise | ½ cup | The base that keeps it creamy |
| Lemon juice | 2 tsp | For that perfect brightness |
| Olive oil | 1 tsp | Adds richness and helps blend |
| Salt | ½ tsp | Adjust to taste |
| Black pepper | ½ tsp | Freshly cracked is best |
| Crushed red pepper flakes | ½ tsp | Optional kick |
| Italian seasoning | 2 tsp | Adds depth and balance |
Pro tip: Try to get your hands on a good block of Parmesan. It melts better, tastes better, and your sauce will thank you.
Tools You’ll Need
- Oven (for roasting that garlic)
- Foil (to wrap the garlic)
- Sharp knife
- Cutting board
- Food processor or blender
- Measuring spoons + cups
- Spatula
- Airtight container for leftovers
Not a lot of gear, and you probably already have everything in your kitchen.
Pro Tips
1. Roast the garlic like a pro
Slice the top off your garlic bulb, drizzle with olive oil, wrap it in foil, and roast at 400°F for 40–45 minutes. When you take it out, the cloves should be buttery soft. This brings out a sweet, mellow flavor that raw garlic just can’t deliver.
2. Blend while warm
If you add the roasted garlic to the blender while it’s still slightly warm (not hot!), it blends more easily with the mayo and cheese, creating a super smooth texture.
3. Don’t skimp on the Parmesan
This sauce lives and dies by the cheese. Use freshly grated Parm—not the pre-shredded stuff, which doesn’t melt or blend as smoothly.
4. Balance the tang
Too lemony? Add a touch more cheese or mayo. Too thick? Drizzle in a little warm water or olive oil and blend again until silky.
5. Let it rest
This sauce gets even better after it chills for an hour or so. The garlic mellows further and all the flavors come together. Worth the wait.
How to Make It
Here’s the full step-by-step. Once you’ve roasted the garlic, the rest is a breeze.
- Preheat your oven to 400°F.
- Slice the top off a whole head of garlic to expose the tops of the cloves.
- Drizzle a bit of olive oil over the garlic, wrap it in foil, and roast for 40–45 minutes.
- Let the garlic cool slightly, then squeeze the soft cloves out into your blender or food processor.
- Add the Parmesan, mayo, lemon juice, olive oil, salt, pepper, red pepper flakes, and Italian seasoning.
- Blend until smooth and creamy. Scrape down the sides and pulse again if needed.
- Taste and adjust seasoning. More cheese? More lemon? You’re the boss.
- Transfer to an airtight container and store in the fridge until ready to use.
It’ll thicken slightly as it chills—just give it a stir before using.
Substitutions and Variations
Here’s how to make this recipe your own (or tweak it for what you’ve got in the fridge):
| Need To | Swap This | For This |
|---|---|---|
| Go lighter | Mayo | Plain Greek yogurt |
| Make it vegan | Parmesan + mayo | Vegan cheese + vegan mayo |
| Dial up the flavor | Olive oil | Garlic-infused oil |
| Add protein | Nothing | Stir in finely shredded rotisserie chicken |
| Lower sodium | Parmesan | Grated Romano (slightly lower salt) |
Want to go spicy? Add a dash of cayenne. Prefer it super cheesy? Toss in a handful of mozzarella for stretch.
Make-Ahead Tips
This sauce keeps well in the fridge for up to 1 week. In fact, it’s even better the next day. If you want to prep it for a party or dinner later in the week:
- Roast the garlic ahead and refrigerate.
- Grate the cheese in advance and store it in a container.
- Blend everything the day of and chill for at least 1 hour before serving.
What to Eat It With
You can literally put this on everything, but here are a few ideas if you’re feeling stuck:
- Toss with pasta and roasted veggies
- Use as a dip for baked potato wedges
- Drizzle over grilled chicken or salmon
- Slather onto sandwiches and wraps
- Serve as a pizza sauce (yep, it works!)

Leftovers and Storage
Store your garlic parmesan sauce in an airtight container in the fridge for up to a week. Glass containers work best to prevent flavor transfer.
Avoid freezing—it can mess with the texture once thawed.
To reheat: gently warm it in a small saucepan over low heat, stirring constantly. Don’t boil it or it might separate.
FAQ
Can I skip roasting the garlic?
You could, but I wouldn’t. Raw garlic is way more aggressive and can overpower the sauce. Roasting makes all the difference.
What kind of mayo should I use?
Use full-fat for best flavor and creaminess. Light works too, but it won’t be as rich.
Can I make this dairy-free?
Yes. Use dairy-free Parmesan (like Violife) and a plant-based mayo. Just note that the flavor will shift a bit.
How long does this last in the fridge?
Up to 7 days in an airtight container. Give it a stir before using.
Is this sauce keto-friendly?
It sure is. Low in carbs, high in fat. Perfect for keto folks.
