Roasted Garlic White Pizza Sauce with Parmesan
A creamy, umami-rich white pizza sauce built on a classic bechamel base infused with sweet roasted garlic and sharp Parmesan. The slow-roasted garlic mellows into a silky paste that anchors dried herbs for a sophisticated, restaurant-quality sauce. Perfect for white pizza, focaccia, or as a base for creamy pasta dishes. This version prioritizes the garlic as the star ingredient rather than a supporting note, creating depth without heaviness.

Tips
Roast garlic ahead: prepare up to 2 days before and refrigerate in an airtight container. The flavor actually deepens slightly.
Whisk constantly while adding milk to prevent lumps. If lumps form, strain through fine sieve before adding cheese.
Use immediately for thinnest consistency, or let cool 5 minutes for a slightly thicker sauce ideal for spreading.
Good to Know
Refrigerate in airtight container up to 4 days. May thicken as it cools; thin with milk when reheating over low heat.
Roast garlic 1-2 days prior. Prepare full sauce up to 4 days ahead and reheat gently. Freezing not recommended due to sauce separation.
Use warm, immediately after cooking for best texture. Spread on dough before adding toppings for white pizza. Works as dip for breadsticks or base for creamy pasta.
Common Mistakes
Add milk too quickly to avoid lumpy sauce; whisk constantly.
Cook flour-butter roux at least 1 minute to avoid raw flour taste.
Simmer sauce fully to avoid thin, greasy consistency.
Don't overcook after adding cheese to prevent separation and graininess.

FAQ
Can I use pre-minced garlic instead of roasting a head?
Pre-minced garlic won't achieve the same sweet, mellow flavor profile. If necessary, saute 3-4 tablespoons minced garlic in the butter before adding flour, but the sauce will taste sharper and less sophisticated.
What if my sauce breaks or separates?
Remove from heat, whisk in 1-2 tablespoons cold milk to cool slightly, then return to low heat and stir constantly. Breaking usually occurs from too-high heat after cheese is added. If still separated, blend with immersion blender.
How long can I keep this sauce and can I freeze it?
Refrigerate up to 4 days in an airtight container. Freezing is not recommended as dairy-based sauce typically separates and becomes grainy upon thawing. Reheat gently on stovetop with added milk.
