If you’re a food blogger with a mega-popular recipe like this Easy Cheesy Zucchini Bake (seen by millions and millions of people on Pinterest), you’ll probably wonder every summer if the recipe will still be popular! But this year I noticed people are starting to visit the recipe again! Have you tried this recipe that’s the most popular zucchini recipe on my blog?

It was my sister Pam who originally found this recipe in Penzeys Back to School Catalog (in 2011!) Pam changed the recipe a bit when she made it, and then I changed it a tiny bit more when I tried it. Pam and I were both so impressed with how this very basic idea of tossing zucchini with a few fresh and dried herbs and cheese and then baking it can produce a cheesy zucchini bake that’s so delicious.

I’ll be honest, I did probably make it a little cheesier than the original recipe, and Jake and I also used a very generous amount of sliced basil. The other change I made was to switch from an 8-inch square casserole dish to one that was 8 inches x 11 inches. I really did like the way this larger dish let the zucchini spread out more so each piece was covered with cheese, but take your choice on that!

And zucchini season is here or neatly here for many of you, so when you get zucchini from your garden or the farmers market, you must try this, or make it again if you’re already a fan!

What ingredients do you need?

  • zucchini, cut in slices or half-moon slices
  • yellow squash, cut in slices or half-moon slices
  • chopped fresh basil (more or less, depending on how much you like the flavor of basil)
  • thinly sliced green onion
  • Dried Thyme (affiliate link)
  • Garlic Powder (affiliate link)
  • grated mozzarella cheese
  • coarsely grated Parmesan, plus a little more for the top if desired
  • salt and fresh ground black pepper to taste

Can you use other types of cheese?

Personally I think the grated Mozzarella and coarsely-grated Parmesan used in this cheesy zucchini recipe is perfect to go with the flavor of basil and fresh zucchini. But if you’d prefer another cheese you can use any white cheese that melts well.

  4. Season with salt and fresh-ground pepper and spread out in the baking dish.
  5. Bake uncovered for 25-30 minutes, or slightly longer. (Until the zucchini is getting tender when you stick a fork into it.)

  7. Serve hot and enjoy.

You'll love this low-carb Easy Cheesy Zucchini Bake which is most popular zucchini recipe of the Top Ten Low-Carb Zucchini Recipes on Kalyn's Kitchen!

Ingredients

  • 2 medium zucchini, cut in slices or half-moon slices
  • 2 medium yellow squash, cut in slices or half-moon slices
  • 4 T chopped fresh basil (more or less, depending on how much you like the flavor of basil)
  • 2 T thinly sliced green onion
  • 1/2 tsp. dried thyme
  • 3/4 tsp. garlic powder
  • 1 cup grated mozzarella cheese (see notes)
  • 1/2 cup coarsely grated Parmesan, plus a little more for the top if desired
  • salt and fresh ground black pepper to taste

Instructions

  1. Preheat oven to 350F/180C.  Spray an 8" x 8" or 8" x 11" baking dish with olive oil or non-stick spray.  (I originally used the small size, but now I prefer a slightly bigger dish.)
  2. Wash the squash and cut in slices or half-moon slices.
  3. Wash basil, spin dry or dry with paper towels and finely chop or slice. (I used a mini salad spinner (affiliate link) to dry the basil and Herb Scissors (affiliate link) to cut into thin slices.)
  4. Slice green onions.
  5. Combine the sliced squash, chopped or sliced basil, sliced green onions, dried thyme, garlic powder, 1/2 grated mozzarella and 1/2 cup coarsely grated Parmesan and stir together until the veggies are coated with cheese and the herbs are well-distributed.  Season with salt and fresh ground black pepper.
  6. Put the mixture in the baking dish and bake uncovered for about 25-30 minutes, or slightly longer. (Pierce a piece of zucchini with a fork to be sure it's mostly tender.)
  7. When the zucchini is nearly cooked through, take the casserole dish out of the oven and sprinkle over the remaining 1/2 cup of grated mozzarella, plus a little more Parmesan if desired.
  8. Put the dish back in the oven and bake 10-15 minutes longer, or until the cheese is melted and nicely browned and zucchini is fully cooked.  Serve hot.
  9. This kept well in the fridge overnight, but mine was gone the next day so I don't know if it would last longer than that!
