Farmers Market Pesto: A Flexible Way to Preserve the Season

One of the easiest ways to preserve the abundance of spring and early summer is by making pesto. Pesto is endlessly adaptable, works with a wide range of greens and herbs, and freezes beautifully for later use. It’s also one of my favorite “clean out the garden basket” recipes — a place for carrot tops, kale stems, arugula, parsley, cilantro, radish greens, spinach, basil, and even edible weeds like chickweed or nettles.At its heart, pesto is less of a strict recipe and more of a preservation method.

Why Pesto Is Such a Good Preservation Recipe

Fresh herbs and greens often come all at once. One week you’re waiting for growth, and the next you have more parsley, kale, or basil than you know what to do with. Turning those greens into pesto helps extend their life while capturing their flavor at peak freshness.Pesto can be:Frozen in jars or silicone traysStored in the refrigerator for short-term useMade dairy-free for longer freezer storageUsed as a sauce, marinade, spread, soup starter, or dipThis is also a wonderful way to reduce food waste and preserve small amounts of greens that might otherwise wilt in the fridge.

Greens & Herb Ideas

This recipe works with almost any combination of greens and herbs, including basil, parsley, cilantro, kale, arugula, spinach, carrot tops, radish greens, beet greens, turnip greens, mustard greens, sorrel, nettles, chickweed, lambsquarters, dandelion greens, chives, chive blossoms, mint, dill, fennel fronds, celery leaves, oregano, marjoram, sage, tarragon, purslane, pea shoots, sunflower shoots, or even a handful of edible flower petals like nasturtium or calendula. Mixing mild greens with stronger herbs often creates the best balance of flavor.

You can also mix and match depending on what’s growing.

Nut & Seed Options

Traditional pesto uses pine nuts, but many local and affordable options work beautifully: Sunflower seeds, Pumpkin seeds, Walnuts, Hazelnuts, Almonds

How to Preserve Pesto

Freeze in Ice Cube Trays

One of the easiest methods. Pour pesto into silicone ice cube trays, freeze, then transfer cubes into freezer bags or containers. This lets you thaw small portions as needed.

Freeze in Small Jars

Use freezer-safe jars and leave headspace for expansion. Label with the date and ingredients.

Skip the Cheese for Long Storage

If freezing for longer periods, consider leaving out cheese and adding it after thawing. This can help preserve flavor and texture.

Add a Thin Layer of Oil

If refrigerating short term, add a thin layer of oil to the top of the pesto to help reduce oxidation and browning.

Ways to Use Pesto
