Tomato Zucchini Casserole With Buttery Parmesan Breadcrumbs
Summer is all about tomatoes and zucchini, am I right? How many things can we make with tomatoes (everything) and zucchini recipes searches are happening all day. If you aren't swimming in zucchini and tomatoes from your garden, then hopefully you are swimming in tomatoes and zucchini from your farmers market/local grocery. They are budget friendly this time of year, so load up.
This tomato and zucchini casserole recipe was born out of a desperation for "what to do with all the tomatoes and zucchini". It's simple, fast, and uses both ingredients we have in summer abundance. You can make a big batch in a large casserole dish or divide it into two batches and save one for later. I divided into two (to make two meals) and then ate them both in two days, pretty much by myself.

INGREDIENTS YOU NEED FOR THIS SUMMER TOMATO AND ZUCCHINI CASSEROLE
Tomato and Zucchini Casserole:
- Fresh Tomatoes: Fresh from the garden, or fresh from your local farmer/grocery.

- Olive Oil: Helps to tenderize the vegetables, also flavor.
- Balsamic Vinegar: Gives a little tang.
- Panko Bread Crumbs: Toasted with butter and crushed red pepper = eat them by the spoonful.
- Butter: BFF's with the breadcrumbs.
- Crushed Red Pepper: Optional, but makes for the most yum breadcrumbs of 2020.
- Grated Parmesan: So good and toasty.
- Dried or Fresh Parsley: If I had fresh, I would use fresh.
- Salt & Pepper: Flavor town. Optional and delicious: use our Basil Salt instead of regular salt!

HOW TO MAKE THIS FRESH FROM THE GARDEN SUMMER CASSEROLE
- Start by tossing the tomatoes and zucchini in olive oil, vinegar, garlic, salt & pepper.
- Arrange them in alternating layers in a casserole dish (see above). Either one large or two small.
- Combine panko, parmesan, butter, crushed red pepper, and parsley in a skillet and toast for a couple of minutes. Spoon it into your mouth, just joking. But actually if you do that (me) there is plenty left over.
- Bake it in the oven on 375° for about 35 minutes, watching for the breadcrumbs to get too browned.
