1. Freezing Homemade Basil Pesto Preserves Nutrients
When you freeze homemade basil pesto, you’re retaining most of the nutrients from the fresh basil, garlic, and olive oil.
Basil is packed with vitamin K, antioxidants, and essential oils that stay largely intact during freezing.
Unlike cooking which can degrade some nutrients, freezing homemade basil pesto keeps the health benefits almost as good as fresh.
So every spoonful of that frozen pesto still gives you a nutritional boost.
2. Freezing Homemade Basil Pesto Saves Money
Let’s be real, fresh basil can be pricey, especially out of season.
By freezing homemade basil pesto, you can buy basil in bulk when it’s cheap and preserve it for later.
You’ll never have to shell out for overpriced store-bought pesto again when you can freeze homemade basil pesto.
And since pesto freezes so well, you can take advantage of sales and harvest seasons without any pressure to use it all immediately.
That’s a win for your wallet and your taste buds.
Best Ways To Freeze Homemade Basil Pesto
Now, let’s get down to the nitty-gritty of how to freeze homemade basil pesto the right way.
There are a few different methods, and the one you choose depends on how you plan to use it later.
Here are the most reliable options for freezing homemade basil pesto.
1. Freeze Homemade Basil Pesto in Ice Cube Trays
The most popular and convenient way to freeze homemade basil pesto is using ice cube trays.
Spoon your homemade basil pesto into clean, dry ice cube trays, filling each compartment almost to the top.
Smooth the tops with the back of a spoon to remove any air bubbles.
Then, place the tray in the freezer for a few hours until the pesto cubes are solid.
Once frozen, pop the cubes out and transfer them to a freezer-safe bag or container.
This way, you can grab exactly one or two cubes of frozen homemade basil pesto whenever you need them.
Each cube is roughly one to two tablespoons, perfect for adding to pasta, soups, or sauces.
This is hands down the best method to freeze homemade basil pesto for portion control.
2. Freeze Homemade Basil Pesto in a Jar or Container
If you prefer a bigger batch, you can freeze homemade basil pesto directly in a glass jar or plastic container.
Just leave about half an inch of headspace at the top because the pesto will expand as it freezes.
To prevent browning on the surface, pour a thin layer of olive oil over the top of your homemade basil pesto before sealing the lid.
This creates a barrier that locks out air and keeps the pesto bright green.
When you’re ready to use it, simply thaw the whole jar of frozen homemade basil pesto in the fridge overnight.
This method is great if you’re meal-prepping or planning to use the pesto within a week or two after thawing.
3. Freeze Homemade Basil Pesto Flat in a Bag
Another neat trick to freeze homemade basil pesto is using a freezer bag and laying it flat.
Scoop your homemade basil pesto into a resealable freezer bag and squeeze out as much air as possible.
Then, lay the bag flat in the freezer and let it freeze into a thin, even layer.
Once it’s solid, you can easily break off chunks of frozen homemade basil pesto as needed.
This method stores very efficiently and thaws quickly compared to a thick block.
Pro Tips For Freezing Homemade Basil Pesto
To get the absolute best results when you freeze homemade basil pesto, you’ll want to follow a few simple pro tips.
These little details make a big difference in flavor and texture after freezing.
1. Don’t Skimp on the Olive Oil
When making your batch specifically to freeze homemade basil pesto, use a generous amount of good olive oil.
A higher oil ratio helps protect the pesto from freezer burn and keeps it silky smooth.
The oil acts as a natural preservative, so don’t be shy with it.
2. Skip or Reduce the Cheese if You Want
You can absolutely freeze homemade basil pesto with parmesan cheese, and it’s totally fine.
However, some folks prefer to add the cheese after thawing for the freshest flavor.
If you want to freeze homemade basil pesto without cheese, just omit it and stir in fresh grated parmesan after thawing.
It’s a personal choice, and both methods work great.
3. Label and Date Everything
This might sound obvious, but always label your frozen homemade basil pesto with the date and contents.
Frozen pesto all looks the same, and you don’t want to mix up your basil pesto with something else.
Put the date on the bag or container so you know exactly how long it’s been in the freezer.
How To Thaw Frozen Homemade Basil Pesto
Thawing frozen homemade basil pesto is just as easy as freezing it.
The best, most gentle way is to move it to the fridge and let it thaw overnight.
For a quicker method, you can set the sealed bag of frozen homemade basil pesto in a bowl of cold water for about 15 minutes.
Avoid using a microwave to thaw it, as the heat can cause the oil to separate and ruin the texture.
Once thawed, give your homemade basil pesto a good stir to recombine any oil that may have separated.
You can also use frozen cubes directly in hot pasta, and they’ll melt right into the dish.
This makes it so easy to use frozen homemade basil pesto without even thawing it first.
So, How To Freeze Homemade Basil Pesto?
You can freeze homemade basil pesto easily with ice cube trays, jars, or flat freezer bags, and it’ll stay delicious for months.
The key is to use enough olive oil, remove excess air, and choose a portion size that fits your cooking needs.
Whether you freeze homemade basil pesto in cubes for single servings or in a big jar for family meals, you’ll always have fresh pesto ready to go.
Hope this guide helps you preserve all that amazing basil so you can enjoy your homemade basil pesto all year round.
