A plate with a slice of zucchini casserole and a fork.The days this week are so gorgeous that makes me wish I could leave my work every day at 3 pm and lie down on the green grass of a beautiful park. Unfortunately, this is not possible, but I am already pretty satisfied spending my one-hour lunchtime having lunch with my coworkers in the small green space we have close to the office.

I think this little break is essential to clear up our minds and get more energy to keep working in the afternoon. I also don’t complain about my office, because it has a huge window with a beautiful view of the city.

I hate when you look at the windows and just see buildings in front of you. It is sad not to be able to see some beautiful views from the window, but that’s not my case.

Ricotta cheese mixture in a bowl with a spoon. As I said I normally bring my lunch from home and I usually cook on the weekends to save time or if it is a quick recipe or salad I just prepare everything before going to work.

For this dish since it is so easy to make I woke up 1.5 hours before leaving and I made this recipe. I had my ingredients all ready the day before and in the morning I just assembled it.

While I was getting ready (taking a shower, changing, putting on makeup…) this delicious zucchini casserole dish was baking in the oven. Then when it was ready I put a piece in my lunch bag and ate it outside with my colleagues that day. Set of two photos showing zucchini slices with sauce and then covered with the ricotta mixture.So, this zucchini, ricotta, Parmesan, and tomato sauce casserole recipe makes a delicious summer recipe. I love recipes that only require the use of one casserole instead of many pots to prepare because it is much more practical and they are usually full of flavor too.

I really hope you can give this recipe a try. Enjoy!

Ingredients 
 

  • 2 cups fresh law-fat ricotta cheese
  • 1 cup parmesan cheese grated
  • 3 eggs
  • 3 zucchinis sliced ⅛" thick
  • 2 ½ cups homemade tomato sauce

Instructions 

  • Preheat oven to 375°.
  • In a medium bowl mix ricotta cheese, ½ cup Parmesan cheese and eggs. Stir well.
  • In a small casserole layer 5 or 6 zucchini slices.
  • Spread some tomato sauce on the top of the zucchinis.
  • Next, place some of the ricotta cheese mixture.
  • Repeat the layers until all your ingredients are all used up.
  • Top with sauce and the other half of Parmesan cheese.
  • Bake 30 minutes covered and 10 minutes uncovered.
  • Let stand about 10 minutes before serving.

Notes

  • The amount of zucchinis you need will depend on the size of them. While larger ones are great, they are a bit more watery than small zucchinis. 
  • Freshly grated parmesan does melt better than pre-grated parmesan cheese. But in a rush, you can use pre-grated!
  • To store: Keep in mind that zucchini is a watery vegetable so the longer you store it, the more the texture changes (this is why I don't recommend freezing this). So, I suggest eating it immediately or only keeping it for 2-3 days in the fridge in an airtight container.
  • To reheat: Reheat the leftover casserole in the microwave until warmed through.

    This looks so yummy and I want to make today. Question, your recipe states 3 eggs but your instructions indicate add ‘an’ egg. Does the recipe call for 3 eggs or one egg? Thanks. 🙂
