This vibrant herb concentrate transforms any dish with its intense basil flavor. I developed this recipe to capture summer’s essence in a jar, perfect for when fresh basil isn’t available.
The process is simple yet precise: blend fresh basil with oil and a pinch of salt until smooth. This creates a versatile paste that keeps the herb’s bright, aromatic qualities intact for months.
Use it as a base for pesto, stir into soups, or spread on sandwiches. The concentrated flavor means a little goes a long way in enhancing your cooking.
Store in the refrigerator for up to a week or freeze in ice cube trays for longer preservation.
Ingredients for Basil Paste
Six ingredients capture summer in a jar. Bright, bold, and endlessly versatile.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Basil Leaves 🌿 | 4 cups | Packed, stems removed |
| Extra-Virgin Olive Oil 🫒 | 1 cup | High quality for best flavor |
| Sea Salt 🧂 | 1 tsp | Fine grain preferred |
| Garlic Cloves 🧄 | 2 cloves | Peeled, optional for depth |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed preserves color |
| Water 💧 | 2 tbsp | For blending consistency |
The basil is everything here—farmers market bunches have more aroma than grocery store clamshells. Look for bright green leaves with no wilting or black spots. Trader Joe’s and Whole Foods usually have decent options if you’re not growing your own. The olive oil should be something you’d happily drizzle on bread (I splurge on California Olive Ranch for this).
No fresh basil? Frozen basil cubes work in a pinch (thaw and drain well first). Prefer a different herb? Swap in cilantro or parsley for a different vibe. The garlic is optional but adds great depth—skip it if you want pure basil flavor. For a smoother paste, strain out the solids after blending (not necessary but nice for sauces).
This keeps 1 week in the fridge with a thin oil layer on top. For longer storage, freeze in ice cube trays—good for 3 months. Thaw only what you need (don’t waste a drop).

- Keeps Like a Dream: A jar lasts me two weeks in the fridge, and I’ll be real: it’s cheaper than buying those tiny tubes at the store.
Step-by-Step Instructions for Basil Paste
Here’s the method. Simple steps, maximum flavor every time.
Step 1: Prep the Basil and Aromatics
Start by removing the stems from the 4 cups Fresh Basil Leaves. Pack them tightly into your measuring cup—this ensures you have enough leaf volume for a vibrant paste. Give them a quick rinse and pat completely dry with a clean towel.
Peel the 2 cloves Garlic Cloves if using. I like to smash them lightly with the side of my knife first—this releases their oils and makes peeling effortless. Set both the basil and garlic aside while you prep the rest.
Step 2: Blend the Base Ingredients
Add the basil leaves and garlic to your blender or food processor. Pour in 1 cup Extra-Virgin Olive Oil and add the 1 tsp Sea Salt. I always use high-quality olive oil here because it makes up half the paste—you’ll taste the difference.
Pulse for 30 seconds until the mixture starts to break down. Stop and scrape down the sides with a spatula. You’ll notice the leaves turn from bright green to a deeper hue as they release their oils. This is exactly what you want.
Step 3: Add the Finishing Touches
With the blender running on low, slowly drizzle in the 1 tbsp Lemon Juice and 2 tbsp Water. The lemon juice brightens the flavor and preserves that gorgeous green color, while the water helps emulsify the mixture into a smooth paste.
Increase the speed to medium and blend for another 1-2 minutes until completely smooth. Stop and scrape the sides again if needed. The finished paste should be thick but pourable—like a loose pesto consistency.
Step 4: Check and Adjust Consistency
Give the paste a taste and adjust the seasoning if needed. If it’s too thick, blend in a little more water 1 tablespoon at a time until it reaches your desired texture. If it’s too thin, add a few more basil leaves and pulse to thicken.
Here’s the thing—this paste will thicken slightly as it sits, especially in the fridge. So aim for a consistency that’s just a touch looser than your final goal. You can always thin it later with water or olive oil when you use it in recipes.
Pro Tips For Making Basil Paste
- Blanch the Basil: Drop basil leaves in boiling water for 10 seconds then ice bath—keeps the paste bright green instead of that sad brown-gray I got my first five tries.
- Use Room-Temp Oil: Cold olive oil won’t emulsify properly, so pull it out 30 minutes early or microwave for 15 seconds—makes the paste cling better to pasta.
- Skip the Stem: Even small stems taste bitter and turn the texture grainy, so strip leaves only and discard the rest—yes, even the tiny ones.
- Add Lemon Last: Stir in lemon juice after blending; adding it too early can curdle the paste slightly, which I learned the hard way with a split batch.

Frequently Asked Questions
Can I use dried basil instead of fresh?
No, dried basil won’t work for this paste. Fresh leaves contain the moisture and oils needed for the right texture. Dried herbs would create a gritty, uneven mixture.
How long does it keep in the fridge?
Properly stored with a thin oil layer on top, it stays fresh for up to 1 week in the refrigerator. For longer storage, freeze in ice cube trays for up to 3 months.
Why did my paste turn brown?
Browning happens when basil oxidizes. The lemon juice helps prevent this, but blending quickly and storing with oil on top also slows discoloration.
Can I make this without a blender?
Yes! Finely mince the basil and garlic, then mix with the oil and other ingredients. The texture will be chunkier but still full of flavor.
