Fresh herbs are expensive and spoil quickly, leaving you with wilted basil or forgotten parsley in the back of your fridge. Freezing is the easiest way to capture peak flavor and have herbs ready whenever you need them—without the guilt of waste. Whether you’re growing your own or buying bundles from the market, these four freezing methods work for nearly every culinary herb and require minimal equipment.
4 Methods for Freezing Fresh Herbs
Each freezing method preserves herbs differently, so choose based on how you plan to use them. Oil cubes work best for cooking, while water cubes suit soups and braises.
What You Will Need
- Fresh herbs (basil, parsley, cilantro, dill, thyme, oregano, mint)
- Ice cube tray or silicone mold
- Good quality olive oil or neutral cooking oil
- Freezer-safe container or resealable plastic bags
- Sharp knife or kitchen shears
- Parchment paper or baking sheet
Steps
Wash and dry herbs thoroughly
Rinse herbs under cool running water and pat completely dry with paper towels or a clean kitchen cloth. Excess moisture will create ice crystals that damage cell structure and degrade flavor. Pat gently to avoid bruising delicate leaves.
Strip leaves from woody stems
For herbs like thyme, rosemary, and oregano, remove individual leaves from thick stems—these stems won’t freeze well. For tender herbs like basil and parsley, you can chop the entire herb including soft stems into small pieces.
Fill ice cube tray with herbs and oil (Method 1: Oil Cubes)
Add finely chopped herb pieces to each compartment of an ice cube tray, filling halfway. Top with olive oil until the herbs are covered. This creates individual portions perfect for sauteing vegetables, finishing soups, or drizzling over finished dishes.
Fill ice cube tray with herbs and water (Method 2: Water Cubes)
Alternatively, fill compartments halfway with herb pieces and top with water or broth. Water cubes work particularly well for herbs going into soups, stews, or sauces where added oil isn’t desired.
Freeze until solid, then transfer to storage containers
Freeze the filled tray for 4-6 hours or overnight until completely solid. Pop the cubes out and transfer to labeled freezer bags or airtight containers. Label with the herb type and freeze date. Cubes will keep for 3-6 months.
Flat-freeze whole sprigs (Method 3: Tray Freezing)
For tender herbs you want to use fresh (not cooked), arrange clean, dry sprigs in a single layer on a baking sheet lined with parchment paper. Freeze for 2-3 hours, then transfer to freezer bags. This preserves appearance and texture better for garnishing.
Vacuum-seal for longest storage (Method 4: Vacuum Sealing)
Place chopped or whole herbs in a vacuum-seal bag, remove air using a vacuum sealer, and freeze. This method excludes oxygen entirely, preventing freezer burn and extending storage life to 8+ months.
- Freeze herbs at peak ripeness—morning after dew dries but before afternoon heat—for maximum flavor concentration.
- Don’t thaw frozen herb cubes before cooking; drop them directly into hot pans or simmering soups so they release maximum flavor.
- Label everything with both herb type and date; frozen herbs lose visual distinction and it’s easy to mix them up.
What to Look For in Freezing Supplies
- Ice Cube Tray Material: Silicone trays are superior to plastic because they release frozen cubes more easily and won’t crack in the freezer. Look for trays with removable dividers so you can customize compartment size for different portions.
- Freezer Storage Containers: Choose airtight, rigid containers or heavy-duty freezer bags that minimize air exposure. Glass containers with snap lids work best for long-term storage, while flat freezer bags maximize space efficiency.
- Vacuum Sealer Quality: A dedicated vacuum sealer creates airtight seals that prevent freezer burn far better than manual bag sealing. Look for models with pulse settings to avoid crushing delicate herbs.
- Oil Quality for Preservation: Use extra virgin olive oil or neutral oils like avocado oil. Avoid butter and coconut oil, which solidify unevenly and can develop off-flavors. Cold-pressed oils preserve more herb aromatics than refined versions.

The best time to freeze fresh herbs is right now—whether you’re harvesting from your garden or buying bundles from the farmers market. Pick a method that matches your cooking style: oil cubes for sauteing, water cubes for soups, flat-freezing for garnishes, or vacuum sealing for maximum longevity. One afternoon of preparation yields three to six months of ready-to-use herbs with minimal waste.
Start small with one batch of your most-used herb. Many gardeners discover they prefer frozen herbs because they’re always perfectly ripe and require zero washing or chopping at cooking time. Within a few weeks, you’ll have a freezer stocked with basil, parsley, cilantro, and oregano cubes that transform weeknight cooking from rushed and basic to flavorful and intentional.
Frequently Asked Questions
How long do frozen herbs last in the freezer?
Frozen herb cubes remain flavorful for 3-6 months with standard freezing, and up to 8+ months with vacuum sealing. Water and oil cubes maintain flavor longer than flat-frozen herbs because the liquid prevents oxidation. Always label with the date so you know when they were frozen.
Can you freeze all herbs the same way?
Most culinary herbs freeze well, but delicate herbs like basil and cilantro are best preserved in oil or water cubes rather than flat-frozen. Hardy herbs like thyme, rosemary, and oregano survive all freezing methods. Avoid freezing fresh mint intended as a garnish—it becomes mushy—but frozen mint is excellent for tea and smoothies.
Do frozen herbs taste different than fresh?
Frozen herbs lose some delicate fresh flavor but retain concentrated taste suitable for cooking. They work beautifully in soups, stews, sauces, and cooked dishes where their slightly softer texture won’t be noticed. Oil-frozen herbs taste closest to fresh because the oil protects volatile compounds from oxidation.
Should you thaw frozen herb cubes before cooking?
No—drop frozen herb cubes directly into hot pans, simmering soups, or sauces without thawing. This preserves maximum flavor and prevents flavor loss that occurs during thawing. Thawing only matters if you’re using frozen herbs as garnish where texture matters, which isn’t recommended.
What’s the best oil for freezing herbs?
Extra virgin olive oil is traditional and flavorful, but neutral oils like avocado or grapeseed oil work well too. Avoid coconut oil and butter, which solidify unevenly and can develop off-flavors. Cold-pressed oils preserve herb aromatics better than refined versions and taste superior in the finished dish.
