Cheesy Baked Zucchini Casserole

Friends, how has August rushed by so quickly? The end of the gloriously hot days, with cool, cool mornings dragging summer away. I love the poem I’m sharing today!

Enjoy this end-of-the-summer Cheesy Baked Zucchini Casserole for an easy weeknight meal! (Or, how about this Summer Squash Casserole made with pesto or these Acorn Squash Sprouted Rice Bowls? YUM! And dessert? These Butternut Squash Granola Parfaits are also delish!)

What you need to make Cheesy Baked Zucchini Casserole

All you need is zucchini, cheese, fresh basil, and big fat heirloom tomatoes.

What I love about zucchini casseroles is you can mix the cheeses, or use different varieties.

We like the crunch of panko bread crumbs on top! So good.

The casserole may be a little watery (always when you cook with squash), so use a slotted spoon or spatula when serving.

Sunriver Skies

Most of our August days have been a whirlwind, with so much activity and summer fun. But then, again, there are days of the week where we intentionally slow down and do almost nothing. We need those days.

“August rushes by like desert rainfall,
A flood of frenzied upheaval,
But still catching me unprepared.
Like a match flame
Bursting on the scene,
Heat and haze of crimson sunsets.
Like a dream
Of moon and dark barely recalled,
A moment,
Shadows caught in a blink.
Like a quick kiss;
One wishes for more
But it suddenly turns to leave,
Dragging summer away.”
– Elizabeth Maua Taylor

Make new connections

Making new connections has been a priority this summer. When I think back to the people we’ve invited over, some we barely knew, it’s been a real blessing to learn about other people’s lives and really get to know them over a shared meal.

Don’t be afraid to ask your guests to contribute to the meal, so you don’t have to do it all.

Building relationships when you might be feeling just a little stuck in your excuses, and maybe even a bit vulnerable, might just be what you need!

Cheesy Baked Zucchini Casserole


  • 2 tablespoons butter
  • 2-3 medium zucchini, sliced thickly
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 2-3 heirloom tomatoes, sliced thickly
  • Gourmet salt, or seasoning
  • 1/2 - 1 cup basil leaves, optional to chop or leave whole
  • 8 oz. mozzarella cheese, sliced thickly - we buy at Costco
  • 1 cup whole wheat panko crispy bread crumbs
  • 1/4 cup Parmesan cheese, optional


  • In a large skillet, heat 2 tablespoons of butter over medium-high heat. Add zucchini; cook 4-5 minutes, stirring frequently, until crisp and tender. Salt and pepper. Remove from heat.
  • Spray a 9x13 pan with cooking spray. Lay the zucchini on the bottom of the pan.
  • Lay the sliced tomatoes on top of the zucchini; place mozzarella slices on top. Sprinkle with your favorite gourmet salt. I used Mountain Mex Sweet Salt Seasoning, but you can use Lawry’s or Trader Joe’s Garlic Salt (in grinder) or whatever flavor you like. Place fresh basil leaves on top (optional to chop or leave whole).
  • Sprinkle bread crumbs on top. (Optional to add Parmesan to the bread crumbs if you want more cheese).
  • Bake at 375 degrees for 25-30 minutes, or until cheese is melted and vegetables are tender.
  • Remove from oven. Allow to sit for at least 5 minutes before serving. Serve with a slotted spoon or spatular because there may be extra liquid on the bottom from the zucchini.
