Lemon Balm Oregano Pesto

Use up the ever abundant perennial herbs with this lemon balm oregano pesto. It’s easy to make, freezes well, and most importantly is delicious.

Versatile Lemon Flavor

Lemon balm does, of course, impart a lemony flavor to this pesto. The final result is still herbal in flavor but lemon mellows out the oregano nicely. Plus lemon as a flavor is incredibly versatile for pasta, soups, chicken, and more.

Earthy Oregano

Oregano is almost as versatile as lemon. In this pesto, it adds a delightful earthy herbal note that works great in plain in old pasta but will work great with a number of vegetables and of course poulty as well.

Customize the Herbal Ratio

The recipe as written as equal parts lemon balm and oregano. This will create a balanced pesto in flavor that can be used for most any dish where pesto is required.

However, a person could easily use more lemon balm than oregano for say using in a chicken salad dressing. Or use more oregano than lemon balm for a pesto to be used on pasta or rice.

Truly adjust the herb ratio based on personal preference. Heck there’s no reason not to make multiple batches of different ratios, just label appropriately.

Seed or Nut Pesto

Pine nuts are the traditional choice when making basil pesto. They definitely impart a unique and delicious flavor. Pine nuts are also extremely expensive.

Pesto does not need to have pine nuts, however.

Most any nut or seed will do in making this (or any) pesto. I opt for sunflower seed kernels most of the time simply because it is the most frugal bulk choice in my local store.

Use whatever is on hand or frugal. There’s no sense in making the most frugal use of the garden harvest to blow the budget on nut or seed choice.

Smooth or Chunky

Most pestos are a very smooth paste-style sauce. I make mine that way most of the time, too. However, keeping a few small chunks of seeds or nuts adds a delightful crunch and texture to final dishes.

To give the chunkier pesto a try, simply add a little less oil and puree just until the desired texture is reached.

Vegan or Not – Your Choice

To add cheese or not to pesto is a personal choice. I rarely add cheese to pesto itself, choosing instead to add it to the dish if and when cheese is necessary.

If you do add cheese to pesto, taste it befor adding additional salt and add salt slowly to avoid too much.

How to Preserve Pesto

There are no safe and approved methods for home canning pesto. However, it freezes delightfully.

I generally freeze it in half-pint jars as that’s as much as I would use at any one time. However, feel free to freeze it in any size jar that is reasonable.

To freeze, pour the pesto into glass jars with straight sides or plastic containers. Leave at least 1″ headspace to allow for expansion. To prevent drying out, pour a little oil over the top of the pesto to keep it sealed and moist.

Use up frozen pesto within six months. It won’t likely go bad after that time but freezer burn and flavor degradation is common.

How to Use Lemon Balm Oregano Pesto

In short, use it anyway you’d normally use basil pesto.

Mix with pasta or rice for a simple but filling dish. It would be incredible in pasta primavera.

Pesto on spaghetti

Slather it on bread instead of mayo for a delicious sandwich.

Use it instead of tomato sauce on your homemade pizza.

I have so much oregano and lemon balm and don't use the lemon balm at all. This looks amazing and I want to make it this week. Thank you.

I can't do garlic; any substitutions for that? Thanks so much!

I would just skip it - obviously the flavor will be different but there's no real good substitution for garlic but I understand it doesn't agree with everyone.

This sounds amazing! Thank you for sharing.

I have plenty of lemon balm, but my oregano isn't very established yet. Which other herbs would you suggest to use instead of oregano? Would basil work with lemon balm?
