I got this zucchini recipe from my mom. It’s one she makes a few nights out of the week when my dad gets his August harvest of summer squash and zucchini. My dad is an avid gardener so they yield lots of zucchini squash and often give them away. I’m usually one of the lucky recipients.
Filled with sliced zucchini, diced onion, garlic, basil and topped with parmesan cheese. This keto side dish is loaded with the flavors of summer.
Yes, zucchini is keto. A medium zucchini has about 6 total grams of carbs and 2 of them are fiber. So one whole zucchini has 4 net carbs. Zucchini is very popular on the low carb diet. Mostly because it is used as a pasta replacement in the form of zoodles.

This turned out incredibly flavorful and I loved how the basil really brought a fresh taste to the dish. The zucchini had the perfect texture and didn’t turn mushy. Great way to use up my garden harvest!
Microwaving for just 6 minutes gave the zucchini a tender bite without getting soggy and that garlic-basil combo smelled amazing while mixing everything up. The Parmesan melted perfectly over the top at the end and added the perfect salty kick. I couldn’t believe how much depth came from such simple ingredients!
I need something different and basic tonight and I enjoyed making it.
