What to serve with this dish

Because this lasagna is nice and hearty, I like serving it with light and simple sides. Something like this lemony romaine and avocado salad would be a great option.

Have extra zucchini you don’t want to go to waste? Whip up these easy roasted zucchini fries with Parmesan! For even more flavor, try my Mediterranean zucchini noodles with goat cheese.

It’s up to you how complex you want to get with your sides. Personally, next to a big slice of lasagna, some mixed greens are usually all I need.

This dish keeps very well in both the refrigerator and the freezer, which makes it a great option for meal-prepping!

You can store any extra slices in an airtight container in the fridge for up to 4 days or in the freezer for up to 3 months.

To reheat, simply bake the lasagna at 350°F until heated through again. It’s perfect for a quick and delicious meal on busy weeknights!
