Can You Blend Basil Stems In Pesto

You can blend basil stems in pesto, and it’s a great way to reduce waste and add extra flavor.

If you’ve been making pesto for a while, you’ve probably found yourself staring at a pile of woody stems and wondering if they’re destined for the compost bin.

The good news is that you can blend basil stems right into your pesto without ruining the texture or taste.

In fact, basil stems are packed with the same aromatic oils as the leaves, so they actually boost the herbal punch of your final sauce.

In this post, we’ll dig into why you can blend basil stems in pesto, how to prep them for the best results, and when you might want to skip them.

Let’s get blending.
 

Why You Can Blend Basil Stems in Pesto

You can blend basil stems in pesto because they’re tender enough to break down in a food processor, especially when you take a few simple prep steps.

The stems contain a good amount of that classic basil flavor, so tossing them out means losing a chunk of the plant’s potential.

Here’s a closer look at why blending basil stems is totally fine, and even smart.

1. Stems Are Tender and Full of Flavor

The key thing to know is that not all basil stems are created equal.

The thin, green stems near the top of the plant are soft and pliable, and these blend beautifully into pesto.

Even the thicker, lower stems can work if you chop them into smaller pieces before tossing them in the processor.

Because the stems carry essential oils, you’ll actually get a more intense basil flavor when you blend basil stems in pesto.

2. The Food Processor Does the Heavy Lifting

A good food processor or high-speed blender can handle basil stems without breaking a sweat.

The blades chop the fibrous bits down into tiny pieces, and those bits integrate into the olive oil and cheese mixture seamlessly.

As long as you’re not using a weak blender or a mortar and pestle, you can blend basil stems in pesto with zero issue.

The result is a creamy sauce with just a hint of added texture, which most people don’t even notice.

3. You Waste Less and Save Money

When you blend basil stems, you’re using the whole herb, and that’s a win for your wallet and the environment.

Most recipes tell you to strip off the leaves and discard the stems, but that’s a habit based on tradition, not necessity.

By throwing the stems into your food processor, you get more pesto from the same bunch of basil.

That makes adding basil stems a budget-friendly move for your kitchen.

How to Prep Basil Stems for Pesto

So you want to blend basil stems in pesto, but you also want the texture to stay silky.

The secret is in how you prep the stems before they hit the blender.

1. Trim the Woody Ends

Not every part of the stem belongs in your pesto.

If the bottom of the stem feels hard, woody, and snaps instead of bending, cut that part off.

Those tough ends won’t break down well and can leave unpleasant chunks in your sauce.

Stick with the tender mid-to-upper stems, and you’re golden.

2. Chop the Stems into Small Pieces

For thicker stems, give them a quick chop with a knife before adding them to the processor.

Smaller pieces mean the blades can grab them easier and turn them into a fine paste.

If you’re wondering how you can blend basil stems in pesto without a grainy finish, this step is your best friend.

3. Blend the Stems First with the Liquid

Here’s a pro tip: start by blending the basil stems with the oil and garlic before you add the leaves.

That gives the stems extra time to break down into a smooth base.

Then, add the leaves, nuts, and cheese and pulse until combined.

This two-step method ensures you can blend basil stems in pesto and still get that velvety texture everyone loves.

When You Might Not Want to Blend Basil Stems

While you can blend basil stems in pesto most of the time, there are a few situations where it’s better to leave them out.

1. When the Stems Are Super Woody

If your basil is old and the stems are thick, dark, and rigid, they might be too fibrous to salvage.

In that case, blending them will give you a stringy, unpleasant pesto.

Just strip the leaves and compost the stems, because no amount of processing will save those tough stalks.

2. When You’re Using a Mortar and Pestle

The traditional way to make pesto is by hand with a mortar and pestle.

But that tool isn’t powerful enough to break down basil stems.

If you’re going the old-school route, stick to leaves only.

But if you’re using a food processor, you’re free to blend basil stems in pesto without worry.

3. When You Want the Absolute Silkiest Texture

Some people prefer their pesto to be completely smooth with zero fiber.

If that’s your goal, you might want to skip the stems entirely.

But honestly, most home cooks won’t notice the tiny flecks of stem in the final sauce.

It’s all about your personal preference.

So, Can You Blend Basil Stems in Pesto?

Yes, you can blend basil stems in pesto, and it’s a fantastic way to use the whole herb.

The stems add flavor, reduce waste, and give you more pesto per bunch of basil.

As long as you trim the woody ends, chop the thick parts, and blend with enough liquid, your pesto will turn out delicious.

If you’ve been tossing those stems, try this trick next time.

You might just find that your pesto tastes even better with the extra herbal kick.

So go ahead, toss those stems into the food processor and enjoy your homemade sauce.
