Why You’ll Love My Summer Roasted Vegetables
- They’re a meal prep lover’s dream. Instead of cooking one veggie at a time, you can cook a whole bunch together! Then, simply reheat any leftovers to enjoy with a variety of meals throughout the week.
- It nudges you to eat more veggies. There’s just something about roasted vegetables that tastes SO good. And when they taste good, you eat more of them.
- It’s the perfect healthy side dish. You can add these veggies to a plate with virtually any main course or use them as the base of a healthy macro bowl. Just add rice and the protein of your choice.
A giant sheet pan of beautifully colorful roasted veggies is truly my happy place. My motto has always been to sneak in veggies at every meal, and this is definitely one of the easiest ways to do that. Instead of boiling or sautéing them individually, just roast an assortment like this!
Truth be told, the inspiration for this came from my Greek sheet pan chicken. For YEARS you guys have been requesting a recipe for just the veggies. And while I did make a few tweaks to this version, it highlights that same fresh, bright, seasonal flavor.
Just toss a few summer veggies in a simple olive oil and herb seasoning, then roast them on a sheet pan until they’re juicy and slightly blistered. The recipe is simple to make, and I’ll often enjoy these veggies on a plate with grilled salmon or grilled chicken breast. I’ve even been known to reheat a portion and top them with two poached eggs for breakfast—sooo good!
Summer Vegetables I’m Using

- Summer squash: I’m using a mix of zucchini and yellow squash, but feel free to use just one kind if you’d like.
- Cherry tomatoes: When tomatoes are in season, let’s make the most of them! I love roasting them until they’re super soft, almost jammy, and blistered. But you can always roast them to your liking.
- Bell peppers: I’m using yellow bell pepper for color variety, but any color works!
- Red onion: I love the way red onions taste after they’ve been oven-roasted. They’re always beautifully sweet!
- Seasoning: The seasoning on the veggies is a simple blend of olive oil, fresh garlic, dried oregano, dried thyme, salt, and black pepper. This gives them just enough flavor without overpowering them.

How To Make Summer Roasted Vegetables


First, season the vegetables. I like adding all the veggies into a large mixing bowl for easier tossing, but you can also season everything directly on the sheet pan. Then drizzle with olive oil and add the garlic, oregano, thyme, salt, and pepper. Toss until everything is evenly coated.

Second, it’s roasting time. Spread the vegetables onto your baking sheet and roast for 25 to 30 minutes at 425°F (220°C). The veggies should be tender and caramelized around the edges, and the tomatoes should be slightly blistered.
How to enhance them for serving: You can add a sprinkle of freshly chopped basil or parsley, top with crumbled feta or goat cheese, and/or add a light drizzle of my balsamic glaze. Lots of ways to make them extra delish!
A Few Roasting Tips
- Cut the vegetables into similar-sized pieces. This ensures they roast more evenly on the sheet pan.
- Avoid overcrowding the pan. If your veggies are piled on top of each other they’ll steam rather than roast. Side note: I usually fail at this one, lol! But it really is best to use two sheet pans rather than one super crowded one.
- Broil for more caramelization. If you love a little char and extra caramelization (as I do), you can switch the oven to broil in the last minute or two. Just make sure to keep a close eye on them.

How I Use These Veggies in Meals
- For an easy, healthy dinner: I love pairing them with simple baked, grilled, or air-fried proteins! A few favorites (in addition to the grilled ones I mentioned in the intro) are baked chicken, baked salmon, air fryer chicken breast, or air fryer salmon.
- For a balanced breakfast: I’ll often serve them up alongside scrambled eggs, poached eggs, or oozy jammy soft-boiled eggs. This is my favorite way to eat more veggies and boost my breakfast fiber!
Storage Tip
Leftovers of these roasted vegetables can be stored in the fridge for 4 to 5 days. Just note that they’ll soften a bit more over time and when reheated (though I don’t mind them that way).

Lisa’s Tips
- If your sheet pan feels a bit too crowded, you can use two separate sheets pans.

Should I Make This a Series?
I’ll admit, after I made this recipe the first thing I thought to myself was… this should be a series. I should make another one for fall, winter, and spring! Because while we typically think of roasted veggies in the cold fall and winter months, they really are great year-round. So what say you? Should I keep this going?
















Personally I would use mushrooms instead of yellow squash.
You can do that as well, Rob! It’s a recipe you can easily customize :)
So easy and delicious. My 4 year old even approved. Great for meal prep and ate all the leftovers.
Glad this got approved by the kids! Enjoy, Courtney :)
I made this tonight, adding small gold potatoes and mushrooms, along with salmon filets toward the end. Turned Temp down to 350⁰ to finish. It was wonderful! Thank you for all of your wonderful recipes!
What a wonderful sheet pan dinner you made, Nancy! Happy to hear these roasted veggies were perfect for it.
Lisa, I love your recipes. I am making this tonight and realized that you did not include the tomatoes in the directions when mixing all of the veggies together before adding the oil. Minor error but thought you might want to edit that. Thank you for your great recipes. You do not need to post my comment I just sent It was just a note to letherknow.
Hi Georgia – Thanks for catching that! I just updated that step in the recipe card :)
No grain needed for a bowl. Use potatoes, plantains, sweet potatoes, rutabagas or even carrots to starch out the bowl.
U can cut potatoes or sweet potatoes into strips after slicing and steam a bit then finish with a quick fry (w/s&p) for a noodle type starch.
You’ve become my favorite online recipe source.
Your recipes tend to be very healthy. In these days of horrible additives and preservatives one needs to know how to cook delicious and healthy things like God intended for us to eat. I keep an old fashioned 3 ring notebook with my favorite recipes from you.
Thank you for sharing your talent. It is appreciated.
Aww, thanks so much, Janice! I’m so glad you’ve been enjoying my recipes! :)
Have not made recipe yet, but will soon. Can you use parchment paper or tin foil on the bottom of the pan? Will it effect the caramel or crispness of the vegetables?
Hi Molly – In general, it’s best not to use parchment paper for a crispier outer layer. But, you can certainly use parchment paper if you’d like!
Yes please make this a series…I love your video content and watch on repeat.
Wonderful, will do! Thanks so much for your support and kind words, Sheila. :)
