Roasted Zucchini, Squash & Tomatoes

Oh summer, how I love you and all the fresh fruit and veggies you provide. During the summer I always have a generous stock of fruits and vegetables in my fridge then winter rolls around and that’s a different story.

It’s like that abundance of nutritious, vitamin packed fruits and veggies gets traded in for an abundance of cavity causing, non-diet-friendly holiday sweets, but I won’t complain there. I love my sweets. But I also love a sheet pan full of roasted zucchini, tomatoes and other yummy veggies!Zucchini, Squash and Tomatoes on a sheet pan ready to be roasted

Roasting Vegetables – Ingredients

I love what a good roasting and a fair amount of Parmesan can do for veggies. Turns drab and dull into fab and flavorful! Even my kids loved these veggies – including my one daughter who always says “hey could you get that green stuff off of there?”

Here’s a list of the simple ingredients I used to make these extra delicious veggies;

  • zucchini
  • squash
  • tomatoes
  • parmesan
  • garlic
  • Italian seasoning
  • dried parsley
  • salt and pepper

Try these veggies (+1 fruit if you want to get all technical – I still have a hard time accepting tomatoes as a fruit. Call it stubbornness I guess but they just don’t seem fruity enough to be labeled as such), this simple side dish will not disappoint!

  • Marie: My 1st ever comment on a recipe and I get a LOT of them on the internet but this one must be rated. I’d give it 10 stars if I could. I made as directed but used a 3 cheese blend (asiago, romano, parm) and I cut up a lg onion into 12 wedges. OMG! My husband went crazy. He just asked me what’s for dinner & I said “chicken & coleslaw”. He said don’t we have any leftover vegs from last night? I had checked earlier and couldn’t find them (just stocked the fridge) figured we ate so searched again and here they are! He was so happy. I’m gonna put them in the toaster oven. Oh, I mixed up the oil and herbs and let it sit overnight. July 11, 2019 at 4:31pm Reply

  • Melissa Martin: I just found this recipe; I would love to make it for a 4th of July cookout. Is it reheatable? In other words, is it as tasty after being reheated? July 3, 2019 at 6:41pm Reply

    • Jaclyn: The texture will be different (softer) but they’ll still taste good. For best results I’d make fresh. July 3, 2019 at 9:19pm Reply

  • Jamie: AMAZING!!!!!! We LOVED this recipe!! One question though, I was looking at the nutritional information and what is the serving size? July 1, 2019 at 4:38pm Reply

  • Ms. Jerry Jo Creech: So delicious. I left out tomatoes and added red onion. Fresh grated Parmesan on top after removing from the oven. Great side for grilled chicken. Going to make a batch to take to work today!!! July 1, 2019 at 5:29am Reply

  • Pam: I loved this recipe. I added a little fresh asparagus and it was fabulous! June 30, 2019 at 1:48pm Reply

  • Lindsay: I made these the other night. I also added lemon juice from one lemon which brightened up the flavor as well. It’s a really good recipe, especially this time of year when zucchini and squash are so plentiful but the usual recipes get old fast. It had lots of flavor and made a delightful side for fish.

  • Patti Pharis: Excellent and easy! My husband said it is the best he has ever had. I used farm fresh squash and zucchini. I also used farm fresh tomatoes that I peeled and chopped. June 8, 2019 at 5:42pm Reply
