That’s when I reach for my favorite recipe for fresh pesto. Because honestly, to me it’s the best part of summer cooking. But even the biggest pesto lover can’t polish off a whole batch in one go. So, learning how to freeze pesto with fresh basil is one of those practical, old-school tricks that goes a long way.

My mum doesn’t waste a single basil leaf. She whips up her own homemade basil pesto, spoons it into small glass jars, sometimes tops it with a thick layer of olive oil, and tucks them away for the winter months. No fancy tools, no plastic gadgets – just real food and real flavor. Her classic pesto recipe is bright, garlicky, and somehow manages to taste like sunshine; even when there’s frost on the windows.

Now, every time I make a batch of pesto sauce, I think of her. I pour that vibrant flavor into small portions, ready to pull out for pasta nights, salad dressings, or a quick spread on fresh sourdough bread. There’s something deeply comforting about spooning your own delicious pesto – made with love months ago – into a steaming bowl of homemade pasta. It’s a great way to bring a taste of summer back to your table when life gets hectic.

So if you’re wondering how to freeze pesto with fresh basil the traditional way – without it turning dull, losing that bright green color, or tasting like freezer frost – you’re in the right place. Let’s get that flavorful sauce tucked away for later use, the old-fashioned way.

Can I freeze my fresh basil for pesto?

Yes, absolutely! You can freeze basil leaves directly or make fresh pesto first. Turning it into pesto keeps that fresh flavor intact. Just use good olive oil and your favorite hard cheese like Pecorino Romano or Parmesan to seal in the aroma.

What is the best way to freeze pesto?

The traditional way (and still my favorite) is to spoon pesto into an ice cube tray or silicone mold. Drizzle each section with a thick layer of olive oil to prevent browning, then freeze. Once solid, pop out your basil cubes and store them in ziploc bags or jars for easy use.

Can you freeze pesto in ziplock bags?

Yes! After freezing in cubes, you can transfer them to ziploc bags. It’s one of the most convenient ways to store freezer pesto. If you prefer a larger portion, spread the pesto alla genovese flat inside the bag before freezing. It’s quick to thaw and saves space in your freezer.

What’s the best container for freezing pesto?

Small glass jars, silicone molds, or plastic wrap-lined containers all work well. If you like individual portions of pesto for pesto pasta or salad dressings, use mini jars or ice cube trays. For larger batches, fill jars halfway, top with olive oil, and seal tightly.

Will pesto turn brown in the freezer?

Sometimes, yes, but it’s easy to prevent. Air is the enemy! Before freezing, cover the surface of the pesto with olive oil or a piece of plastic wrap pressed directly on top. This old Genovese basil trick helps preserve that bright green color and keeps your delicious sauce fresh-looking.

How to Freeze Pesto: Step-by-Step

Step 1: Gather Your Tools

Before you start freezing your homemade pesto, grab what you need:

Clean ice cube trays, silicone molds, or small freezer-safe jars
Ziploc bags or airtight containers for storage
Extra virgin olive oil
A spoon or spatula
Labels and a marker (trust me, you’ll thank yourself later!)

Whether it’s store-bought pesto, or your own homemade basil pesto, freezing works beautifully as long as you use good-quality containers and keep the air out.

Step 2: Portion the Pesto

Spoon your delicious pesto into the molds or jars in small portions – about one to two tablespoons per cube. This makes it easy to grab the exact amount you need for a single serving, homemade pasta, or a flavorful sauce for cherry tomatoes and roasted veggies.

Step 3: Seal the Surface

This is where the magic happens. Smooth the top of each portion, then drizzle a thick layer of olive oil to completely cover the surface of the pesto. This helps lock in that fresh flavor and prevents oxidation (the main issue behind browning pesto).

Step 4: Freeze Until Solid

Place your trays or jars flat in the freezer. Once they’re fully frozen, pop out the cubes and transfer them to ziploc bags or small containers. Label each with the date and type (like “pistachio pesto” or “pesto genovese”) for easy grab-and-go cooking.

Step 5: Store for Later

Keep your freezer pesto for up to 6 months. When you’re ready to use it, take out what you need and let it thaw at room temperature for 15 – 20 minutes. Or just toss a cube straight into a little hot pasta water or a pan. It’ll melt beautifully into a delicious sauce.

Skip the cheese before freezing if you want the smoothest texture. Just stir it in after thawing.
If your pesto separates after defrosting, stir it gently at room temperature until creamy again.
