This is a simple low-carb side recipe made with just five ingredients (or three if you don't count salt and pepper). I wouldn't say it tastes like "real" noodles but it is a great low-carb alternative to pasta.
In this keto recipe I used my Wild Garlic Pesto but you can use any pesto sauce with your preferred herbs, nuts/seeds and spices. Homemade pesto takes just 5 minutes to make so I rarely use ready made.
If you don't have the ingredients to make your own, feel free to use any store bough pesto sauce — just watch out for added fats and ideally choose a product that only uses extra virgin olive oil.
Instead of pesto, you can keep the fennel noodles plain and use them just like you would zucchini noodles or palmini. Try with other sauces such as this easy marinara or our super popular keto cheese sauce.
Now when it comes to fennel, it's not as widely used as zucchini. I'll address some of the most common questions below.
Is Fennel Keto?
Fennel is a tasty low-carb vegetable that's ideal for a keto diet. Fresh fennel contains 4.2 g net carbs per 100 grams. Apart from the low carb count, fennel is packed with nutritional benefits; it can aid digestion and improve bowel movement.
How Does Fennel Taste?
Fennel has a pleasant licoricey flavour and a nice crunch. It can be eaten both raw and cooked. It's perfect in salads such as this crunchy slaw. Apart from using the raw bulbs in salads, fennel can be braised, added to any roast vegetables, soups and stews.
How To Prepare Fennel
Preparing fennel bulbs is easy. First you need to trim off the hard fennel stalks. These are too tough to eat but will be an excellent addition to homemade stocks for a flavour boost. Simply place the stalks in a ziploc bag and freeze until you make the next batch of bone broth.
We are making fennel "noodles" so the next step is to cut the fennel bulbs in half and then each half in quarters. Cut off the hard core (add to the ziploc bag with the stems) and then slice very thin noodles lenghtwise. You can also use a mandolin or a food processor with a grating blade attachement.
Can I Have Fennel on a Low FODMAP Diet?
If you're following a low FODMAP diet, keep the serving size of this meal at half a cup per serve. The pesto doesn't use garlic cloves and instead it uses wild garlic (also known as ramsons) which should be safe for a low FODMAP diet. Similar to leeks and spring onions which are often used to replace onions, wild garlic leaves are used as an alternative to garlic cloves.
