How to Freeze Fresh Herbs in Souper Cubes Trays for Year-Round Flavor

Fresh herbs add a burst of flavor to any dish, but they can wilt, spoil, or lose their potency within days of being picked. Whether you grow your own basil, cilantro, parsley, or mint, or you buy bundles from the store, finding a way to preserve them without sacrificing taste is a game-changer for home cooks and meal preppers alike. Freezing herbs in silicone trays is one of the simplest and most effective methods—and Souper Cubes trays are perfectly suited for the job.

In this guide, we’ll walk you through the best techniques for freezing fresh herbs in Souper Cubes trays, from choosing the right herbs to storing them for maximum flavor. You’ll learn how to make herb cubes, herb-infused oils, and even herb butter portions that you can pop out and use directly in soups, stews, sauces, and more. Plus, we’ll highlight a few Souper Cubes products that make the process even easier.

Why Freeze Fresh Herbs in Silicone Trays?

Freezing herbs in silicone trays offers several advantages over drying or refrigerating. First, silicone is non-stick and flexible, making it easy to pop out perfectly portioned cubes without any waste. Unlike plastic containers, silicone trays are freezer-safe, dishwasher-safe, and reusable, which aligns with a sustainable kitchen. Souper Cubes trays, in particular, are made from high-quality, food-grade silicone that resists stains and odors, so your herb cubes won’t pick up any unwanted flavors.

Another key benefit is portion control. When you freeze herbs in standard ice cube trays, the cubes are often too small for a full recipe. Souper Cubes trays come in various sizes, including the popular 1-cup option, allowing you to freeze larger portions that are ideal for soups, curries, or braises. This means you can grab one or two cubes and have exactly the amount you need, reducing waste and saving time during meal prep.

• Silicone trays are non-stick and flexible for easy removal.
• Portion control with larger cubes (e.g., 1-cup) suits most recipes.
• Freezing preserves the herb’s flavor better than drying for many varieties.

Choosing the Right Herbs for Freezing

Not all herbs freeze equally well. Soft, tender herbs like basil, cilantro, dill, mint, and parsley freeze beautifully because they have high moisture content. Woody herbs like rosemary, thyme, oregano, and sage also freeze well, but they benefit from being chopped or minced before freezing to release their oils. For best results, always use fresh, clean herbs—avoid any that are wilted or browning.

When preparing herbs for freezing, wash them gently in cold water and pat them completely dry with a clean towel or salad spinner. Excess moisture can cause ice crystals to form, which may dilute the flavor. Once dry, remove any tough stems (especially for herbs like rosemary or thyme) and chop the leaves to your desired size. For whole-leaf freezing, you can leave small leaves like thyme or oregano intact.

• Soft herbs: basil, cilantro, parsley, mint, dill.
• Woody herbs: rosemary, thyme, oregano, sage (chop first).
• Always dry herbs thoroughly to prevent ice crystals.

Step-by-Step: How to Freeze Herbs in Souper Cubes Trays

Start by selecting your Souper Cubes tray. For herb cubes, the Freezer Tray - 1-Cup is an excellent choice because it holds a generous portion—perfect for adding to a pot of soup or a pan sauce. If you prefer smaller portions, you can use the MyMilk Breast Milk Trays (which come in 1-ounce compartments) for single-serving herb cubes. Simply fill each compartment about three-quarters full with chopped herbs.

Next, choose your liquid base. You can freeze herbs in water, olive oil, or broth. Water is neutral and works for most herbs, but oil helps preserve the flavor of delicate herbs like basil and also prevents freezer burn. Broth adds extra flavor and is ideal for savory dishes. Pour the liquid over the herbs until they are just covered, leaving a little space at the top for expansion. Gently tap the tray to release air bubbles.

Place the tray in the freezer for 4–6 hours or until fully solid. Once frozen, pop the cubes out and transfer them to a labeled freezer bag or airtight container. For easy identification, use a Water-Based Paint Kitchen Marker to write the herb name and date on the bag. This step is crucial if you freeze multiple herb varieties, so you can grab the right cube without guessing.

• Use Freezer Tray - 1-Cup for large portions, MyMilk trays for small cubes.
• Liquid options: water, olive oil, or broth—choose based on intended use.
• Label bags with a Water-Based Paint Kitchen Marker for easy identification.

Creative Ways to Use Frozen Herb Cubes

Frozen herb cubes are incredibly versatile. Toss a basil-oil cube into a simmering tomato sauce for instant flavor, or drop a parsley-water cube into a pot of chicken soup. Herb cubes also work well in marinades, salad dressings, and even cocktails—try a mint cube in lemonade or mojitos. For roasted vegetables, melt a rosemary-broth cube over the veggies before roasting.

Another favorite method is making herb butter cubes. Mix softened butter with chopped herbs (like garlic chives, parsley, and thyme), then spoon the mixture into a Souper Cubes tray. Freeze, pop out, and store in a bag. These butter cubes are perfect for spreading on bread, melting over steak, or adding to mashed potatoes. The No Mess Serving Utensils can help you scoop and portion the butter mixture cleanly.

• Basil-oil cubes for pasta sauces and pesto.
• Mint-water cubes for beverages and desserts.
• Herb butter cubes for quick flavor boosts.

Tips for Long-Term Storage and Best Results

For maximum freshness, use your frozen herb cubes within 6 to 12 months. While they will remain safe to eat beyond that, the flavor may gradually fade. Always store the cubes in airtight freezer bags or vacuum-sealed bags to prevent freezer burn. If you have a vacuum sealer, you can use it with Souper Cubes vacuum seal bags for an extra layer of protection.

When cooking, add frozen herb cubes directly to hot dishes without thawing. This prevents sogginess and releases the flavor gradually. If a recipe calls for fresh herbs, use about twice the volume of frozen cubes (since freezing concentrates the flavor slightly). For example, if a recipe needs 2 tablespoons of fresh basil, use 1 frozen basil cube (if your cube is about 1 tablespoon).

• Store cubes in airtight bags or vacuum-sealed bags.
• Add frozen cubes directly to hot dishes—no need to thaw.
• Adjust quantities: frozen herbs are slightly more concentrated.

Freezing fresh herbs in Souper Cubes trays is a simple, efficient way to enjoy garden-fresh flavor all year long. With just a little prep, you can have basil, cilantro, rosemary, and more ready to drop into your favorite recipes.
