Ingredients You’ll Need
With only a few essentials, each ingredient in Preserving Summer: Basil in Oil brings something special—be it bold flavor, silken texture, or a burst of gorgeous color. Don’t skip or substitute too much, because their simple magic is what makes this preservation so delicious.
- Basil leaves: Choose vibrant, unblemished leaves for the brightest flavor and deep green color—absolutely key to that “fresh from the garden” taste year-round.
- Olive oil: Use a good quality extra virgin olive oil; it infuses the basil and helps lock in both taste and nutrients.
- Kosher salt: Essential for drawing out a little moisture and enhancing the basil’s natural sweetness—it also helps preserve everything beautifully.
How to Make Preserving Summer: Basil in Oil
Step 1: Prepare the Basil
First, wash your basil leaves gently under cool water to remove any dust or hidden garden guests. Lay them out on a clean towel and pat them completely dry—excess moisture can spoil your oil, so take your time with this step. The brighter and fresher your leaves, the more stunning your finished Preserving Summer: Basil in Oil will be.
Step 2: Layer Basil and Salt in the Jar
Select a clean, dry canning jar with a plastic lid (metal lids can react with the oil). Start by placing a single layer of basil leaves on the bottom, then sprinkle a pinch of kosher salt over them. Continue alternating layers of basil and salt, gently pressing down as you go, until your jar is three-quarters full. This layering isn’t just pretty—it’s key to even preservation and flavor distribution throughout your Preserving Summer: Basil in Oil.
Step 3: Add Olive Oil
Slowly pour olive oil over the stacked basil and salt. Pour gently, letting the oil seep into every nook and cranny until it completely submerges the basil. Don’t rush this step; a good soak ensures the leaves are fully covered, no air bubbles are trapped, and flavors infuse perfectly. This is where the magic of Preserving Summer: Basil in Oil really starts to happen.
Step 4: Seal and Store
Once the basil is covered, seal the jar tightly with a plastic lid. Give it a gentle shake to make sure everything is settled. Store the jar in a cool, dark cabinet for at least one month, allowing flavors to meld and mature. Patience is part of the tradition—when you finally pop the lid, you’ll be rewarded with an aromatic, emerald-hued oil worthy of any summer memory.

Make Ahead and Storage
Storing Leftovers
Once opened, always keep your Preserving Summer: Basil in Oil in the refrigerator, ensuring the basil remains submerged in oil. It should stay fresh for two to three months—as long as the leaves remain below the oil line, you’re in good shape!
Freezing
If you want to extend its life even longer, freeze the basil oil in small silicone molds or ice cube trays. Once solid, pop them out and store in freezer bags—each cube delivers instant flavor to soups, sauces, or sautés. Freezing is a brilliant way to enjoy Preserving Summer: Basil in Oil months after the garden is gone.
Reheating
Let refrigerated or frozen portions return to room temperature naturally. Never microwave the oil, as direct heat can muddle the delicate basil aroma. A gentle stir is all it takes to revive any separation—just be sure to use a clean spoon each time for best flavor and safe storage.
FAQs
How do I keep the basil from turning dark in the oil?
Thoroughly drying your basil before layering and keeping the leaves entirely submerged in oil are key. Exposure to air can cause discoloration, so check occasionally to push any stray leaves back under the oil.
Can I use other types of salt?
For best results, stick to kosher salt. It melts and seasons evenly without overpowering the tender flavor of the basil. Table salt can sometimes make the mixture too salty or cause clumping.
Does Preserving Summer: Basil in Oil need to be refrigerated?
After the initial month-long infusion in a cool, dark place, move the jar to the refrigerator after opening to keep it fresh, aromatic, and safe from spoilage.
How can I use the leftover basil leaves after the oil is gone?
The basil leaves themselves become soft, salty, and fully infused—you can finely chop them to stir into dressings, pasta, or even whipped into compound butter for a burst of basil flavor.
Can I mix in other herbs?
Absolutely! Try adding a little fresh oregano, thyme, or even chili flakes for a personal twist, but keep basil as the star to maintain the unique taste of Preserving Summer: Basil in Oil.
