Recipe Highlights
Notes on Ingredients
One of the many things I love about this recipe for Italian veggies, is that it can be made with endless combinations of vegetables and change up the spices based upon what you have and or are craving. Use this recipe as a starting point and let your produce drawer guide you.

- Potatoes: Any variety of potatoes work well. Yukon gold potatoes, russet potatoes, red potatoes, even sweet potatoes.
- Onions: Yellow, sweet, or red onions all work well.
- Other Vegetable Options: I love the combination of bell peppers, zucchini, squash, and tomatoes with the Italian seasonings and potatoes. However, cauliflower, eggplant, mushrooms, and/or broccoli are great ideas to add as well.
- Seasonings: For Italian veggies, obviously this recipe calls for Italian seasoning. I also recommend adding crushed red pepper flakes for a bit of spice, salt, and pepper. I also add both garlic powder and garlic cloves. The garlic powder adds mellow garlic undertones, while the garlic cloves become slightly sweet as they roast and add tremendous flavor to the roasted vegetables.
- Olive Oil: Extra-virgin olive oil has a high-smoking point and the best flavor for Italian roasted vegetables.
- Parmesan: Totally optional, but encouraged if you aren't dairy-free.
How to Make Roasted Italian Vegetables
The following tips are provided to help you achieve perfect results. You will find the ingredient quantities and detailed instructions in the recipe card at the bottom of this post.
- Start with the Potatoes & Onions. Because potatoes take longer to roast than the other vegetables, it is best to season the potatoes and onions and let them roast in the oven while you chop and season the remaining vegetables. This will ensure that the potatoes become tender and caramelize without the other vegetables burning.

- Add More Vegetables. Remove the partially roasted potatoes from the oven and add the seasoned peppers, squash, and tomatoes to the pan. Return to the oven to finish roasting.

- Finish with Cheese. Once the vegetables are tender and slightly caramelized, remove from the oven and if desired, I strongly encourage adding freshly grated parmesan cheese. Afterall, parmesan makes every Italian dish better. 😉

Serving Suggestions
- As a Side Dish: Italian Vegetables pair well with so many entrees. A few of my favorite entrees to serve with these veggies are chicken marsala, Instant Pot Italian beef, chicken piccata, lemon baked cod, and chicken florentine.
- As a Vegetarian Entree: Serve the roasted vegetables with a side of Italian bread and bread dipping oil or over Instant Pot quinoa for added protein.
- Add to Salads, Quiche, or Frittatas: Top a salad with these roasted Italian veggies or use as the filling for a quiche or frittata.

This is perfect for a summer gathering that I have coming up! Love it!
This dish was absolute amazing. We had it for a main dish for dinner. We are vegan so no Parmesan and it was great! We used Newman’s Own organic marinara as that is our go-to.
I am so glad you enjoyed Krista! It does make a delicious vegan option without the Parmesan.
This was delicious!! The marinara sauce gave it wonderful flavor. I did end up peeling the potatoes, since my family doesn't care for the peels. Also, if you let it sit a bit after it comes out of the oven, the vegetables soak up more of the marinara sauce and juice from the tomatoes and get even more flavor. Thank you for a wonderful, healthy recipe.
Oh I am so glad you enjoyed Elaine! I love that you adapted this to meat your family's preferences. And thanks for the tip 😉
Love how versatile this recipe is!
Thank you!! We just had it for a meatless meal last week!
I love roast veggies and often make them with salmon, but I've never tried topping with marinara sauce.
I love that you just pop the whole dish in the oven and let it do its magic.
Trying this very soon. Thank you!
You bet. Enjoy!
This recipe looks delicious! I just started eating vegan, and as long as I use vegan cheese, I can totally eat this! Thanks!
Amy,
This is totally delicious without any cheese. I would leave the vegan cheese off for this recipe. I hope you enjoy.
