It’s All About the Layers!

Each layer of the lasagna is prepared individually, here are some tips for each layer!

Red Sauce- You want to make sure that you simmer the red sauce for 15-20 minutes to let all of the flavors simmer and turn into a delicious sauce. By adding the butternut squash and mushrooms to the sauce, you are starting the cooking process for the butternut squash, so don’t skip the simmer!

When layering the sauce with the noodles be sure you add enough sauce on top of the lasagna noodles, it helps them cook!

Cheese Sauce- We made the cheese sauce with part ricotta, part Greek yogurt, parmesan, mozzarella, thyme, and garlic! You want to combine all the ingredients for this cheese sauce in a bowl and spread it evenly throughout the whole lasagna.

Noodles- Boil the noodles so they still have a little bite to them. This is important because they will continue to cook in the oven.

It is also very important that when you strain the water from the noodles, you lay the noodles out flat and sprinkle them with oil so they don’t stick together.
