How to make herb salts at home, with three preparation method options. Plus, a rosemary salt recipe that requires just 5 ingredients, a few minutes to prepare, and has tons of uses!

As is probably fairly obvious to anyone who pays attention to my blog, I love to make things from scratch and have dedicated the last 2-3 years to food DIYs. There are homemade 1-ingredient butter,  Super Easy Homemade Cream Cheese, Powdered Milk, not to mention tons of vegan alternatives, and – recently – items like this homemade Italian seasoning. I have even made flaky salt and chili salt. Now, it’s the turn of herby flavored salt and this homemade rosemary salt. 

Flavored salts are a quick and simple way to pack tons of flavor into meals – not to mention that they are a great way to preserve fresh herbs from your garden (other than drying them or preserving them in oil, as I mention here). I’ve found that homemade flavored salts tend to get even better as they sit/age over time (though they do eventually start to lose flavor, but that’s months away!).

Plus, herb salts also make a great homemade gift option for foodies or even party/wedding favors and work out much more cost-efficient than store-bought options!

The Ingredients

• Salt – I use coarse sea salt. Kosher salt also works very well.
• Rosemary – I use rosemary from my garden. Use fresh or dried.
• Sage – use fresh or dried.
• Oregano – use fresh or dried.
• Garlic flakes or powder – you could also use fresh garlic if drying the salt out.

Other Flavored Salt Herb Options

• Lemon Zest/Orange Zest/Lime Zest
• Basil/Thai basil
• Bay Leaf
• Celery
• Cilantro (Coriander)
• Coriander
• Dill
• Fenugreek
• Lavender
• Marjoram
• Mint
• Parsley
• Thyme
• Tarragon
• Zaatar Mix

You can also use dried chili and chili flakes or ingredients like minced garlic (for when you’re drying the salt!). You can also experiment with spices such as paprika, curry powder, or even vanilla (vanilla salt is actually delicious).

How To Make Rosemary Salt

Technically there are three ways to prepare any herb salt: the first is to use fresh herbs and store the salt in the fridge (for short-term use), the second is to use fresh herbs and dry them with salt in the oven (or at room temperature), the third is to use dried herbs (home-dried or store-bought).

Below I’ll provide options for all three methods.

Step 1: Prepare the herbs

First, wash the herbs (rosemary/sage/oregano) and pat dry with a kitchen towel. Then separate the stems from the leaves. We are only using the leaves. The stems give a bitter taste to the salt so you can discard/compost them.

If you’re using dried herbs then skip this step.

Step 2: Blend the flavored salt

For finely ground salt

Put the salt, herbs, and garlic together in a mixer or grinder. Blend till it is a nice smooth refined green salt.

At this point, you can decant it into a glass jar and put it away. If you used fresh herbs, you can also continue with step 3.

For more coarse/chunkier salt

First put only the herbs in a mixer or grinder. Blend till you achieve a texture you like – it can be a little finer or chunkier.

Then add the salt and pulse just a couple of times to combine the mixture. Doing this allows you to keep bigger salt crystals for a more coarse salt texture.

Pour into a glass jar and put it away. Or, if you used fresh herbs, you can also continue with step 3 and dry the salt.

Step 3: Dry the salt mixture

To prolong the shelflife of salt mixed with fresh herbs, it’s best to dry the mixture. Spread the salt mixture over a large baking sheet (or multiple sheets, if making a large batch).

To dry at room temperature: leave in a well-ventilated area, near a window if possible. This can take several days to dry completely depending on the weather/humidity (best for warmer climates).

To dry in the oven: place the baking tray in the oven and allow the salt to dry at 230ºF/110ºC. The time will vary depending on the herbs you use – I suggest paying attention between the 30-45 minute marks and then increasing time as needed, until dry to touch.

Top Tip: Allow the salt to sit for 1-2 days before using it to allow all the flavors to develop. Though you can also use it immediately.

How To Store

When using fresh herbs, without drying the mixture, store it in an airtight container in the fridge, and use within 2-3 weeks.

If dried, then this salt will last well up to a year (technically, it will keep indefinitely if completely dry – but the flavor will eventually decrease).

How To Use

• Rubbed over proteins – tofu or grilled meat/chicken/fish.
• Mixed into homemade butter – to make compound butter.
• Roasted potatoes – like these Rosemary Garlic Crispy Roasted Potatoes or Roasted Purple Potatoes.
• Mashed potato and other potato dishes.
• Other roasted veggies (and dishes like corn on the cob or Simple Veggie fries).
• Over pasta dishes – like this Creamy Vegan Mac and Cheese, or Vegetarian One-Pot Pasta bake.
• Sprinkle over popcorn!
• Sprinkled over and into bread recipes – like this Simple Homemade Multigrain Bread Recipe or flatbreads like focaccia.
• Use with eggs – like these Fluffy Cloud Eggs, a Veggie Omelette, or even this tofu scramble.
• Over pizza – like this Butternut Squash Pizza or Homemade Neapolitan pizza.
• With fresh salad veggies like tomatoes and cucumber.

Top Tips/Notes

• The color and flavor of the rosemary salt will fade over time (months after making), so you may want to top it up with some additional herbs.
• Sturdier herbs work best for simple herb salts and create the best results. Delicate leafy herbs like cilantro, parsley, and dill work best as part of a blend (in my experience).
• If you don’t have a food processor/blender, you can finely chop the herbs by hand and/or use a mortar & pestle.
• Top Tip: You can dry herbs out in the microwave too. This is something a reader actually let me know – so it isn’t something I’ve tried – but I’m told to spread them over a few layers of paper towel and dry for between 1-2 minutes, in spurts of 20-30 seconds.
