Recipe Ideas for Fermenting 9 Summer Vegetables

Take advantage of the abundance of summer vegetables with these recipe ideas for fermenting them!

We love summer vegetables which come sun-kissed to the market stalls. It’s a celebration of flavour, colour, and freshness!

Fermentation increases the nutritional values of vegetables while developing new flavours. Fermenting your vegetables also allows you to extend the harvest season, so you can enjoy the summer a little longer.

Through fermentation, rediscover the emblematic summer vegetables, such as cucumbers, tomatoes, and beans, but also vegetables that we would never think of fermenting, such as garlic flowers and aromatic herbs!

Here are 22 recipes and ideas for fermenting summer vegetables. To learn more about fermenting vegetables, check out our complete guide to lacto-fermentation or all of our fermented vegetable recipes.

Summer garlic to ferment (recipe ideas)

Garlic

Although available year-round, Canadian garlic is usually harvested in early August. In lacto-fermentation, garlic reigns in strength. It lends its pronounced taste to many recipes: pickles, kimchi, carrots, Lebanese turnips, etc.

However, we also like to ferment it on its own! Garlic cloves can be left to ferment in brine for several weeks or even years. Over time, the garlic softens and becomes almost sweet.

Note: is your garlic turning blue or green? It’s perfectly normal and harmless. This is a chemical reaction due to the acidity of the fermentation. Learn more : Why Does Fermenting Garlic Turn Blue (or Green)?

Recipe for Lacto-Fermented Garlic Cloves

1. Stack the garlic cloves in a jar and cover them with 3% salt brine.
2. Let it ferment for at least 1 month, or forget about it in a cupboard until the next time you move.

Eat the garlic cloves like candy (or almost…)

Recipe for Lacto-Fermented Garlic Paste

1. In a food processor, puree the garlic cloves and 2% of their weight in salt.
2. Place in a jar and let it ferment for a week at room temperature.

Recipe for Fermented Garlic With Honey (or Fermented Honey With Garlic)

Small Summer Cucumbers to Ferment

Cucumbers (Pickles)

Lacto-fermented pickles are a classic in fermentation and for a good reason! They’re crunchy, tasty, and will enhance any burger or sandwich.

However, since cucumbers contain a lot of water, they are more likely to soften during fermentation.

Here are some tips for successful pickling:

● Use Kirby type cucumbers for pickling
● Add a source of tannins (grape leaves, tea, horseradish)
● Remove the ends to avoid softening by the enzymes
● Plunge the cucumbers into an ice water bath
● Let it ferment for a few days only

Recipes for Lacto-Fermented Dill Pickles

1. Stack the cucumbers in a jar with flavourings (garlic, pepper, dill).
2. Cover with 4% salt brine.
3. Let it ferment for 4 to 7 days.

For details, check out our lacto-fermented pickles recipe.

1. Cover with 4% salt brine.
2. Let it ferment for 4 to 7 days.
3. Slip into your next martini.

Cucumber Kimchi Recipe

Stuffed cucumber kimchi (oi sobagi) is a very popular side dish in Korea.

2. Let it ferment for one day at room temperature.

Fennel to Ferment

Fennel

Fennel shines in fermentation! It retains its crispness and delicate aniseed flavour, while becoming slightly tenderer and tangier. Try it on its own in brine, or with other vegetables (cabbage, cauliflower, carrots).

We like to combine it with lemon, cilantro, or Indian flavours, for an unusual experience. A vegetable to discover!

Fennel leaves can also be used as seasoning with carrots or pickles. The bulb can be cut into chunks or chopped and added to sauerkraut or chutney. However, remove the stalk and stems, which are too fibrous.

Sauerkraut and Fennel Recipe

Add a fennel bulb (or two) to your favourite sauerkraut recipe!

1. Thinly slice the fennel bulb and the cabbage head.
2. Massage with 2% salt to draw out the water.
3. Place in a jar, pack well, add weight and lid.
4. Let it ferment for 2 to 4 weeks.

Recipe for Fennel Chutney

The aniseed flavour of fennel is particularly interesting in chutney.

1. Mix chopped fennel with onions, cranberries, apples, and 2% salt.
2. Let it ferment for a fortnight.

Enjoy with your favourite grilled meat.

Recipe for Lemon Lacto-Fermented Fennel

2. Cover with 2% salt brine.

Fresh Herbs on a Stall

Aromatic Herbs (Basil, Cilantro, Parsley, Etc.)

Can aromatic herbs be lacto-fermented? Of course, they can! It’s a great way to keep the freshness of the abundant summer herbs.

During the lacto-fermentation process, aromatic herbs keep their essential oils, unlike dried herbs. Be careful not to ferment for too long, or you will end up with a mush. Unless, of course, that is the desired texture!

Recipe for Lacto-Fermented Basil

1. Pack basil leaves and 2% salt in a jar.
2. Let it ferment for one to two weeks.

Serve on your homemade pizzas. For more information, see our recipe for lacto-fermented basil.

Serve with your BBQ grilled meats.

2. Place in a jar with 2% salt brine and let it ferment for about a week.

Use on fish or salads.

Fresh Summer Garlic Flower

Garlic Flower

We love garlic cloves, but we can’t get enough garlic flowers! Early summer, garlic sprouts and forms a long, curled stalk with a flower. This stalk tastes a lot like garlic, only fresher. In addition, garlic flowers do not give you bad breath!

Garlic flowers are used everywhere you would use garlic. One of our favourite ways to enjoy them is as a pesto. It goes on our pasta, pizzas, and toast in the morning.

Note: garlic flowers have not been tested against vampires. Use at your own risk.

Green beans to ferment

Beans

To prevent the beans from softening during fermentation, use very fresh beans and keep the fermentation shorter. Different varieties of beans can be used: green, yellow, purple, etc.

Get inspiration from flavourings used for carrots or pickles.

Recipe for Pickled Green Beans

1. As with dill carrots, stack your beans vertically in a jar with garlic, pepper, and dill.
2. Cover with 2% salt brine and a weight to keep the beans submerged.
3. Let it ferment for one to two weeks.

Serve with your favourite Bloody Caesar.

Recipe for Yellow Beans with Lemon

2. Cover with 2% salt brine and a weight.
3. Let it ferment for one to two weeks.

Summer corn ready to ferment

Corn

Lacto-fermented corn is a real discovery! Because it naturally contains high levels of sugar, corn evolves considerably during the fermentation process. Taste it at different stages of fermentation to see how you like it.

To avoid alcoholic fermentation, add a source of lactic acid bacteria. You don’t want to end up with corn wine! (although…)

Recipe for Fermented Corn Cob

1. Cut the corn cobs into chunks.
2. Place in a large jar and cover with 2% salt brine.
3. Let it ferment for 4 to 12 days.

Hot Peppers to Ferment in Summer

Chili Peppers

Ready to enjoy the best hot sauce of your life? Ferment your chili peppers!

During fermentation, chilies lose some of their texture. However, their flavour deepens, and they become ideal for making hot sauces. The acidity of a lacto-fermentation is not as intense as that of a vinegar sauce, and the flavours are more nuanced.

We recommend wearing gloves unless you are adventurous… but avoid rubbing your eyes!

Lacto-Fermented Hot Sauce Recipe

In a jar, stack chili peppers (of your choice), carrots, a clove of garlic, and half an onion.
1. Cover with 2% salt brine and let it ferment for about 3 weeks.
2. Drain and set aside the brine.
3. Puree the vegetables in a blender.
4. Add brine until desired consistency.

For more details, see our fermented hot sauce recipe.

Fermented Chili Paste Recipe, Sambal Oelek Style

1. In a food processor, puree the chili peppers, garlic, lemon juice, and 2% salt.
2. Transfer to a jar and let it ferment for 7 to 10 days.

Put it on everything, everywhere!

Recipe for Lacto-Fermented Jalapeño Slices

1. Cut (with gloves, please) the jalapeños into slices.
2. Stack in a jar with a few cloves of garlic.
3. Cover with 2% salt brine and let it ferment for about a week.

Serve on your next nachos.

Ready to Ferment Tomatoes

Tomatoes

Tomatoes are THE vegetable that you always have plenty of. Try to use them up by lacto-fermenting them!

You can lacto-ferment whole tomatoes or cherry tomatoes in brine. However, the results are moderately interesting. Tomatoes contain a lot of water and become very soft during fermentation.

Therefore, let’s opt for lacto-fermented salsa, where tomatoes can shine.

Recipe for Lacto-Fermented Tomato Salsa

1. Chop all the ingredients for a traditional salsa and add 2% salt.
2. Place in a jar and let it ferment for a week.

For more details, check out the lacto-fermented tomato salsa recipe.
