September is the season for zucchini–courgettes in French. There are so many kinds, and so many ways to prepare them.
In the raw: Zucchini and chickpea salad
I’ve eaten zoodles (zucchini noodles) all my life. My grandma used to make a wonderful creamy tomato soup with zucchini noodles. No spiralizer for Grandma. She was all about the knife, the wooden spoon and the arm muscles, though I think she did have a mandoline. 
Following in her footsteps, use a mandoline to make fettuccini of 3-4 medium-size courgettes, about 6-8 inches long. (Grandma grew everything in her garden to size XXL, but you’d do well to avoid baseball-bat zucchini, with their big seeds.) Salt and let sit a while in a colander to soften them up and become more noodle-like. Rinse and pat off some of the water with a paper towel.
In a large bowl, mix the zoodles with a drained 15 oz. can of chickpeas (you can cook up a batch from dried, but that requires planning, whereas this recipe is quick and dirty), some chopped fresh herbs (parsley, mint, basil–your choice), a swirl of olive oil, a splotch of red-wine vinegar and some pepper. Because the zoodles were salted, taste before adding any more.
I’m usually of the opinion that more is more when it comes to salads, and I tend to include anything and everything that’s in the fridge. But I left this salad simple and it was delicious, the zucchini and chickpeas both being mild and not in combat for dominant flavor. I’ve also done it with halved cherry tomatoes, which add color.
Les courgettes sont cuites
(Actually, the saying is “les carottes sont cuites”–meaning “all is lost” or “the jig is up.” I saw many dubious explanations for the origin of this phrase–dubious, because if one can’t spell correctly in a piece about etymology, well, les carottes sont cuites. Fortunately, the book Légumes d’hier et d’aujourd’hui–Vegetables of yesterday and today–says it’s because in a mix of root vegetables, carrots are the last to be done.)
The first time I ever had French food was in a fancy restaurant in the Midwestern city where I grew up. I was still in high school, being high-falutin’ going there. I remember the white-washed brick walls, which were SO radical in the ’70s, the simple black furniture, and the zucchini. Considering I could peer through the windows and see that interior regularly over the years, I suspect that ALL I really remember about that meal is the zucchini. Simple matchsticks of zucchini, sautéed in butter. Nothing haute about it, but you need to use good butter (NOT margarine). The zucchini caramelize in the browned butter and then melt in your mouth.
Here you have it:
Cut some small zucchini into matchsticks. You want smallish ones so they aren’t full of seeds. Count on at least one per person–they melt down. You can peel them, but that (1) has less nutrition, (2) is more work and (3) is wasteful (a future post is coming on a French cookbook about using peelings and scraps). The easiest way to make matchsticks is to first cut coins and then make little stacks of the coins and cut them into slivers.
Brown a tablespoon or two of butter in a skillet. If your skillet is big and you have a lot of zucchini, add more. When the bubbles subside, add the zucchini and stir. It should be hot enough that the zucchini brown without getting mushy. Almost seared. That’s it. A little salt and pepper. A perfect side to any main.
Yes, you can vary this by sautéeing minced garlic or onions before adding the zucchini. And you can add fresh or dried herbs, whether oregano, basil, parsley or rosemary. But sometimes, the simple version is a revelation, especially when the brown butter makes the zucchini sing.
May I add that the great Prosper Montagné, native of Carcassonne and author of the original Larousse Gastronomique, has a similar recipe in his book Les Delices de la Table that I translate here as closely as possible to word-for-word: cut three peeled zucchini into coins not too thin. Salt them and sauté in a skillet with butter. Let them brown well. Sprinkle with chopped parsley. Serve in a vegetable bowl (légumier).*
He goes on to note: Habitually, one sweats them by lightly sprinkling with salt, and one dredges the courgettes, as well as eggplant, in flour before sautéing them. We discourage this system. Zucchini and eggplant sautéed in oil or butter cook perfectly put into the skillet as they are. 
Far be it from me to argue. By the way, for those first chilly days of fall, check out this great zucchini soup recipe.
*Do you notice that there’s exactly one measurement in his recipe, and it’s three zucchini? But of indeterminate size. All the old recipes are like this!
