Hollandaise sauce lasts 1 to 2 days in the fridge when homemade, provided you store it in an airtight container at 40°F (4°C) or below.
Commercially packaged hollandaise, such as a Knorr sachet or a jarred sauce, keeps up to one week unopened, but once opened it follows the same 1-to-2-day window as the homemade version.
Because the sauce is a warm emulsion of egg yolks, butter, and lemon juice, it is highly perishable: never leave it at room temperature for more than two hours, and refrigerate any leftovers promptly.
Under proper refrigeration at 40°F (4°C) or below, hollandaise keeps only a short time because its egg yolks and butter are both perishable.

How Long Can Hollandaise Sauce Last in the Fridge?
Under proper refrigeration at 40°F (4°C) or below, hollandaise keeps only a short time because its egg yolks and butter are both perishable. Homemade sauce should be used within one to two days. Commercially packaged hollandaise contains preservatives and lasts longer while sealed, but the clock resets to one to two days once the seal is broken.

Fridge Shelf Life (at 40°F / 4°C or below)
Always transfer the sauce to a sealed container immediately after preparing or opening it, and place it in the coldest part of the fridge (the back of the bottom shelf) rather than the door, where the temperature fluctuates.

What Is Hollandaise Sauce?
Hollandaise is a classic French emulsion sauce known for its smooth, buttery flavor and delicate consistency, most famously served over Eggs Benedict as well as vegetables and fish. Its short shelf life comes directly from its ingredients, each of which plays a specific role:
Ingredient
Purpose
Egg yolks
Provide richness and act as the emulsifying agent
Melted butter
Adds flavor and creates a velvety consistency
Lemon juice (or vinegar)
Cuts through the richness and adds brightness
Salt
Enhances the overall flavor profile
Cayenne / white pepper
Introduces a subtle heat
The raw or barely-cooked egg yolks are exactly why hollandaise must be refrigerated promptly and used quickly, unlike shelf-stable condiments.
To keep hollandaise safe and prevent it from absorbing fridge odors, follow these steps:
Cool quickly: Let the sauce cool from serving temperature before sealing it, but do not leave it out longer than two hours total.
Use a sealed container: Transfer the sauce into a clean, dry airtight container to limit exposure to air and contaminants.
Label and date: Mark the container with the preparation or opening date so you can track the 1-to-2-day window.
Avoid cross-contamination: Use clean utensils every time you scoop the sauce to keep bacteria out.
Placement inside the fridge matters. Store the container at the back of the bottom shelf, the coldest and most temperature-stable spot, and keep it away from the door. Do not stack heavy items on top of the container, which can crush it or cause leaks. Expect the chilled sauce to firm up and possibly look slightly grainy; gentle reheating restores it.
Because hollandaise carries a real risk of foodborne illness once it turns, check it before every use. Discard the sauce if you notice any of the following:
Indicator
What to look for
Smell
Sour or off odor
Color
Discoloration, such as a grayish hue
Mold
Any visible mold or spores on the surface
Texture
Separation or curdling that will not whisk back together
Taste
An unusual or off taste (a last-resort check only)
Freezing hollandaise is possible but not generally recommended, because the cold breaks the emulsion and separates the butter, leaving the thawed sauce grainy or split. If you must freeze it to avoid waste, it will keep for up to about one month. Follow these steps:
Cool the sauce before packaging.
Transfer to a freezer-safe airtight container or heavy-duty freezer bag, pressing out as much air as possible to prevent freezer burn. Freezing in an ice-cube tray lets you portion small amounts.
Label and date the container, and use it within a month.

To use frozen sauce, thaw it overnight in the refrigerator, then reheat gently while whisking vigorously to bring the emulsion back together as much as possible. See also how long can food stay in a freezer without power.
How to Reheat Hollandaise Sauce
Reheating is the trickiest part, since high heat scrambles the yolks and splits the emulsion. Keep it gentle:
Use gentle, indirect heat: Warm the sauce in a heatproof bowl set over simmering water (a double boiler) rather than directly on the burner.
Whisk constantly: Continuous whisking keeps the sauce emulsified as it warms and helps it re-combine if it has separated in the fridge.
Add liquid sparingly: If the chilled sauce is too thick, thin it with a few drops of warm water or lemon juice, added drop by drop while whisking.
Do not rush: The sauce should be warm to the touch, not hot.
For safety, reheat the sauce until it reaches an internal temperature of 165°F, which kills bacteria that may have grown during storage, and use a food thermometer to confirm. Reheat only the portion you plan to eat: each reheating cycle raises the risk of foodborne illness, so never reheat the whole batch more than once. If the sauce has already been in the fridge longer than the recommended one to two days, do not reheat it at all.

Because the sauce keeps only a day or two, put leftovers to work quickly. It is versatile well beyond brunch:
Eggs Benedict variations: Spoon it over classic, smoked-salmon, or vegetable Benedict, or stir a little into scrambled eggs or an omelet.
Vegetable drizzle: Pour over steamed or roasted asparagus, broccoli, cauliflower, or Brussels sprouts.
Seafood sauce: Add a dollop to poached fish, grilled shrimp, or a seafood crepe.
Sandwich and burger spread: Use it in place of mayonnaise for a rich, buttery, tangy twist.
Potato and baked dishes: Transform boiled or baked potatoes, or fold it into casseroles and gratins for a luxurious texture.
When repurposing it, adjust the consistency by warming gently for drizzling, balance its richness with light or acidic ingredients, and brighten it with fresh herbs such as dill or chives. The table below summarizes some pairings:
How long is hollandaise sauce good for in the fridge?
Homemade hollandaise is good for 1 to 2 days when refrigerated promptly in an airtight container at 40°F (4°C) or below. Opened commercial hollandaise lasts the same 1 to 2 days.
How long does packaged or Knorr hollandaise sauce last in the fridge?
Sealed commercial hollandaise, including brands like Knorr, can last up to one week in the fridge because it contains preservatives. Once opened, use it within 1 to 2 days, just like homemade sauce. Always follow the printed use-by date if it is sooner.
Can you keep hollandaise sauce in the fridge, and will it keep?
Yes. Refrigeration is the correct way to store hollandaise and is essential for safety, since its egg yolks and butter are perishable. Keep it in a sealed container at the back of the bottom shelf and use it within 1 to 2 days.
Can hollandaise sauce be frozen?
You can freeze it, but it is not recommended because freezing breaks the emulsion and the thawed sauce often turns grainy or separates. If necessary, freeze it airtight for up to one month, thaw overnight in the fridge, and whisk hard while reheating gently.
How do you store hollandaise sauce?
Cool it briefly, transfer it to a clean airtight container, label it with the date, and refrigerate it immediately at 40°F (4°C) or below in the coldest part of the fridge. Never leave it at room temperature for more than two hours.
How do you reheat hollandaise sauce safely?
Reheat it slowly over a double boiler, whisking constantly, until it reaches 165°F. Thin it with a few drops of warm water or lemon juice if needed, and reheat only the portion you will use, once.
How can you tell if hollandaise sauce has gone bad?
Discard it if it smells sour or off, shows discoloration or a grayish hue, develops mold, or curdles and will not whisk smooth again. When in doubt, throw it out.
