Sabrina’s Tips
To ensure an even cook, I recommend you cut your vegetables into similar sizes and don’t overcrowd the pan. Dense veggies (carrots, squash, broccoli) can be cut slightly smaller.

About this Recipe
The idea for eating the rainbow may seem like a candy slogan, but since each vegetable brings different vitamins and flavors to the table this recipe is actually a great way to add a lot of depth to your meals without making multiple dishes.
Pairing Suggestions
This recipe makes a great side dish to a protein main. I love pairing it with a simple chicken recipe like buttermilk chicken or Baked Ranch Chicken. It would also pair well with pork recipes like BBQ pork chops or Ultimate Garlic Pork Loin Roast.
Variations
- Red: If you’re not a fan of red bell pepper, you can make this recipe with beets, radishes, red potatoes, or tomatoes.
- Orange: For more orange vegetables try orange bell pepper, butternut squash, pumpkin, acorn squash, or sweet potatoes.
- Yellow: Yellow bell pepper, yellow beet, yukon potatoes, and yellow tomatoes also taste delicious roasted.
- Green: You can sub out the green vegetables with Brussels sprouts, green bell pepper, asparagus, green beans, zucchini, or snow peas.
- Purple: You can sub out the purple vegetables with eggplants or purple carrots.

Hi Sabrina,
Do you think I could substitute butternut squash for the yellow squash in this recipe?
You sure can; however, butternut squash take longer to cook than yellow squash so keep that in mind. Let us know how your Roasted Vegetables turn out!
So easy, yet so good! I made a huge pan of a variety of veggies and it was gone immediately. A great way to use up whatever’s in the fridge.
Sabrina, these are delicious! Instead of plain salt and pepper, I use Famous Dave’s Meat Seasoning. I know it sounds crazy, but give it a try and tell me what you think. Also great that way on the grill!
Thanks for the suggestion.
Just wondering if you could use purple, green or orange cauliflower for one of the colors, or if the cauliflower would need to roast a lot longer than the other veggies. We love cauliflower but I’ve never roasted it, don’t really know how long it would need to cook.
You could totally use one or more of it.
I only have regular vegetable oil on hand. Can I substitute the canola oil with it?
Yes 🙂
This was and will remain helpful to all of us. Loved it 🙂
Thanks
How do you suggest reheating?
Reheat them at 425 degree f oven for 15-20 minutes.
We loved these veggies – even my son, who can be real picky about some things. Planning on making them again soon!
Its a lovely dish, that’s for sure! I cut the calories by cutting way down on the oil. I use real evoo and lightly oil my fingers and pick up each piece to allow a fine coat on the veggies. I don’t like oily roasted vegetables. But with this one change it’s just as pretty and good!
I’m glad you enjoyed and were able to make it fit to your taste!
The idea is fun and it is healthy so I gave it a two. I used coconut oil because I know that roasting veggies with regular oil isn’t a fam favorite. We love the taste of the other. But with just salt and pepper it was very bland. I added some more spices to kick it up. I also cooked chicken on our cast iron with coconut oil and made a quick sauce using lemon juice, zest, cornstarch and some broth. Thank goodness I did because the sauce saved the meal. They ate it and I would do it again with the changes I made but it’s not something we will keep on the mix as written.
I’m trying this recipe tonight!! Can you send the link to the knife you are referring to, please?
Sure, the knife I loved is the curved rock and chop one from this set.
Served this over rice, with homemade tahini sauce and (accidentally) some ghost pepper hot sauce. This’ll go into our weekly rotation – easy to make, and delicious for sure.
That sounds amazing!
This looks amazing! Could it be done with extra virgin olive oil? Or is that too a high a temperature?
No, EVOO would be fine to use!
FINALLY – an easy, versatile roast vegetable recipe that is quick and, well, “one size fits all”-style!
This was so easy, tasty, and pretty!
I made it with red bell pepper, carrots, garlic (yellow-ish, right?), zucchini, and cabbage.
I will be making this again and again…and again. 🙂
Thanks for sharing!
Thanks Zofia!
I made this for my wife last night, reducing the quantity obviously. We both loved it. My broccoli was on the thick stalk so I peeled that and sliced the tender inside into 1/2″ pieces and used it too. Delicious!
Coincidently I bought mushrooms the other day just before I received your garlic butter mushrooms email. I’m looking forward to that.
Thank you for coming back to let me know how much you guys enjoyed it! I think it was serendipitous that you bought mushrooms 😉
Roasted veggies are my absolute favorite….I love the rainbow!

Gorgeous pan of veggies! I love being able to cook it all on one pan!
Oh, yes! Easy clean up is a bonus!!
I love these rainbow roasted vegetables more than I can say. Isn’t Mother Nature glorious?
Definitely!
Gorgeous and what a great idea! This would be a fun cooking project to involve my kids with!
