Frequently Asked Questions
What are Creamy Garlic-Parmesan Glazed Onions?
They are a gourmet side dish featuring tender boiling onions in a rich garlic and Parmesan cheese sauce.
What kind of onions should I use?
Use 3 lbs of small boiling onions for the best texture and presentation.
Can I use regular onions instead of boiling onions?
While you can use pearl onions, boiling onions are preferred for their size; regular large onions would need to be chopped and wouldn't have the same effect.
How do I peel 3 lbs of boiling onions quickly?
Blanching them in boiling water for a minute and then shocking them in cold water makes the skins slip right off.
Why should I use a non-aluminum saucepan?
A non-aluminum pan prevents the sauce from reacting with the metal, ensuring it stays beautifully pale.
What is a roux?
A roux is a mixture of equal parts fat and flour used as a thickening agent for sauces.
Why shouldn't the roux brown?
For this specific creamy sauce, keeping the roux pale ensures the final glaze remains light and white rather than brown.
How long should I cook the roux?
Cook it for 2-3 minutes until it resembles cake frosting to remove the raw flour taste.
Why do I use cold milk with a hot roux?
Using cold milk with a hot roux creates a temperature contrast that helps produce a smooth, lump-free sauce.
Can I use hot milk?
Yes, if your roux has cooled down, you should use hot milk to achieve the necessary temperature contrast.
What type of milk is best for this recipe?

How do I prevent lumps in the sauce?
Whisk the milk in gradually and ensure the temperature contrast between the roux and the milk is maintained.
When do I add the Parmesan cheese?
Add the Parmesan cheese and garlic powder after you have whisked the milk into the roux.
Can I use fresh garlic instead of garlic powder?

How long do the onions need to boil?
Boil the onions for about 15-20 minutes in a separate pot.
How do I know when the onions are done?
