Summer Veggie Casserole

{updated recipe}

In the summer we usually take a break from all of those heavy meals we love — but that doesn’t mean you have to compromise on taste. I think summer is the best time of year because we have so many fresh ingredients. This Summer Veggie Casserole is the perfect example of that. It combines all of your favorite summer vegetables and makes a delicious, healthy meal.

I think summer is also a great time of year to experiment with different vegetables.  And the best place to find these veggies is a farmers market.  They can offer you samples and ideas on how to prepare it.

There are many variations of this casserole but I always stick with my favorites like tomatoes, yellow peppers, zucchini and more!

Slices of potatoes make up the base of this casserole. I cut them about a 1/4 inch thick. First, coat the casserole dish with olive oil before placing the potato slices on top. Season with salt and pepper.

In a separate mixing bowl, I combined the onion and yellow pepper slices, the garlic, and thyme.

Place about half of the onion/yellow pepper mixture on top of the potatoes.

Next I just started layering the remaining veggies starting with my tomato slices. I used tomatoes on the vine, I think these are so colorful and the perfect size.

Then the zucchini slices. I added more olive oil, salt & pepper on top to help in the cooking process.

The topping is parmesan cheese. I love fresh parmesan cheese so I shredded the cheese on top. This gets covered up with aluminum foil and cooks for 40 minutes covered on 350 degrees.

Remove the cover after 40 minutes and cook for another 20 minutes uncovered at 425 degrees. This gives the veggies a nice browning.

We usually eat this casserole as a meal but you can pair it with just about anything including chicken and fish.

It’s incredibly tasty and perfect for summer!
