FAQ
Before you opt out of cottage cheese, know that it has a very different texture when blended in the food processor. It becomes smooth and creamy, adding a delicious richness to the lasagna. But if you’d rather use another cheese, we recommend ricotta!
The main difference between Tuscan seasoning and Italian seasoning is that Tuscan seasoning has added red pepper flakes, dried bell peppers, and minced garlic.Â
We don’t recommend it, as you end up with a very oily lasagna. Use at your own risk!

here’s a tip!
Make sure not to overprocess, as some grittiness is great for pesto’s texture. If your pesto is too thick, add more olive oil by the teaspoon and pulse until smooth. Set aside.Â
try it!
Homemade Pesto
We don’t recommend making this lasagna with store-bought pesto! Which means you’ll need to whip up a batch of our super flavorful 5-minute pesto.
If you have any leftovers, store them in an airtight container in the refrigerator for up to 3-4 days. To reheat, place slices of lasagna in the microwave or bake in a 350ºF oven until warmed through.
