Can I use other types of cheese instead of Parmesan?
Parmesan is my go-to, but mozzarella gives you a gooey, melty finish and cheddar adds a sharper bite. Both work great here.
What can I serve with Cheesy Keto Basil Zucchini?
I usually serve this next to grilled chicken or fish. It also goes well with a simple green salad if you want a lighter dinner.
How can I store leftovers?
Keep leftovers in a sealed container in the fridge for up to 3 days. Reheat in the oven or microwave.
Is this recipe suitable for meal prep?
Yes, this is a great meal prep side. Make it ahead and reheat portions during the week.
Can I add more vegetables to this recipe?
For sure. Bell peppers and spinach both work well mixed in. I sometimes add cherry tomatoes too.

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.
