How Long Does Tzatziki Last?

Storage times and freshness tips for tzatziki in different conditions.

Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.

Opened in Refrigerator
5-7 days after opening for commercial products; 3-5 days for homemade tzatziki.

Signs of Spoilage

Visible mold (green, black, pink, or fuzzy spots), significant liquid separation beyond normal whey (excessive wateriness), discoloration (yellowing, greyish tint), bubbles or fizzing on the surface, a strong sour/yeasty/rancid/ammonia-like odor, slimy or gritty texture.

How to Check

  1. Visual Inspection: Look closely for any signs of mold growth on the surface or sides, unusual colors, or excessive liquid pooling.

  2. Smell Test: Take a small whiff. If it has a strong sour, 'off', yeasty, or ammonia-like smell that is not its fresh tangy aroma, it's likely spoiled.

  3. Texture Check: Use a clean spoon to scoop a small amount. If it feels slimy, gritty, or unusually curdled, discard it. Safety Warning: If any of these signs are present, discard the tzatziki immediately. Avoid taste-testing if spoilage is suspected.

Storage Tips

Always use clean utensils when serving to prevent introducing bacteria. Keep tzatziki in its original, tightly sealed container or transfer to an airtight container to minimize air exposure. Store on a middle or upper shelf in the refrigerator, where temperatures are more consistent. Never leave tzatziki at room temperature for more than 2 hours.

Unopened in Refrigerator
Up to the 'best by' or 'use by' date printed on the packaging, typically 1-2 weeks for commercial products if no date is present.

Signs of Spoilage

Expired date, bulging or swollen container (indicating gas production from spoilage), visible mold through the packaging, unusual liquid separation not typical for the product.

How to Check

  1. Check Date: Always adhere to the manufacturer's date.

  2. Visual Inspection: Look for any signs of container damage, bulging, or obvious mold growth. If the container looks compromised or smells 'off' even unopened, do not consume.

Storage Tips

Always store tzatziki at or below 40°F (4°C) in the refrigerator. Avoid purchasing containers that are already bulging or damaged.

Frozen
1-2 months for best quality, though it remains safe indefinitely. Texture will degrade significantly after this period.

Signs of Spoilage

Significant freezer burn (ice crystals, dried-out appearance), and most notably, a very watery, separated, or grainy texture upon thawing. It may also taste bland or have an 'off' freezer taste.

How to Check

  1. Visual: Check for freezer burn before thawing.

  2. Texture After Thawing: Upon thawing, observe the consistency. If it's completely separated, watery, or curdled, its quality is compromised. Stirring vigorously might help somewhat, but the original creamy texture will not return.

  3. Taste (Optional): If visual and texture checks are acceptable, taste a small amount. If it tastes bland or has an unpleasant 'freezer' flavor, it's best to discard or use in cooked applications.

Storage Tips

Freezing is generally not recommended for tzatziki because its dairy base (yogurt) and high water content (cucumber) lead to significant textural changes upon thawing, resulting in a watery, grainy product. If you must freeze, portion into small, airtight, freezer-safe containers, leaving headspace for expansion. Thaw slowly in the refrigerator. It's best used in cooked dishes (like marinades or sauces) where texture is less critical, rather than as a fresh dip.
