6 servings

  • 1 medium potato, peeled and cut into 1/2-inch pieces
  • 1 medium yam, peeled and cut into 1/2-inch pieces
  • 1 red bell pepper, seeded and cut into 1/2-inch pieces
  • 2 carrots, peeled and cut into 1/2-inch pieces
  • 5 tablespoons olive oil
  • 1 red onion, thinly sliced into rings
  • 2 small or 1 large zucchini, cut crosswise into 1/4-inch-thick pieces
  • Salt and pepper
  • 2 large ripe tomatoes, cut crosswise into 1/4-inch thick slices
  • 1/2 cup grated Parmesan
  • 2 tablespoons dried Italian-style bread crumbs
  • Fresh basil sprigs, for garnish

Preheat the oven to 400 degrees F.

Toss the potato, yam, bell pepper, carrots, and 2 tablespoons of olive oil in a 13 by 9 by 2-inch baking dish to coat. Sprinkle with salt and pepper and toss until coated. Spread vegetables evenly over the bottom of the pan.

Arrange the onion slices evenly over the vegetable mixture. Arrange the zucchini over the onion. Drizzle with 2 tablespoons of oil. Sprinkle with salt and pepper. Arrange the tomato slices over the zucchini.

Stir the Parmesan and bread crumbs in a small bowl to blend. Sprinkle the Parmesan bread crumbs over the vegetables in the baking dish. Drizzle with the last tablespoon of olive oil.

Bake uncovered until the vegetables are tender, and the topping is golden brown, about 40 minutes. Garnish with fresh basil sprigs, if desired.

    An amazingly delicious vegetable dish. Takes a while to cut it all up, but it is worth it in the end. I've made this twice already and my mouth is watering just thinking about it!
    Delicious but also not a very substantial dish. Add LOTS of cheese. Could also try adding couscous, quinoa, or some other grain to make this more filling.
    This was delicious. The only thing I did differently was to use a couple of poblano peppers instead of the bell pepper. I also used Panko crumbs and chopped up fresh oregano, thyme and parsley for the topping since I had no Italian bread crumbs. I used a mandolin to slice all the veggies except the tomato. Only the onions failed to cook all the way through after 40 minutes. Since they were red onions it didn't really matter. All and all, a tasty way to use the goodies in the garden!
    Really great dish with amazing flavor, especially for an all-veggie bake. I'd use a bit less olive oil next time, since it tends to pool a the bottom of the dish. Also, I gave it a little extra kick by sprinkling a layer of feta on top of the whole thing after it came out of the oven. A tiny bit less healthy but it added a delicious twist. Highly recommend.
    I bring this with me to potlucks and work parties. Everyone LOVES it and wants the recipe. It is one of my favorite recipes of all time. A great way to use veggies from the garden. Because I live at a high altitude, I bake it for at least 45 minutes. I also use more olive oil than is called for in the recipe. Soooooo yummy!!
    Tasty. Not super flavorful but my kids ate it so I will definitely make it again.
    I was surprised how wonderful this is (I'm not much of a cook But hey, it's got yams and potatoes, how could it miss. Went light on the Olive oil. 
    This recipe was absolutely FANTASTIC! A friend of mine who doesn't even really like vegetables took a second helping! The tastes are wonderful--I will definitely make this again ... it is a WINNER!
    Easy and delicious, I added slices of eggplant on top of everything prior to the tomato slices and sprinkled all with basil before putting in the oven. Great vegetarian side dish
    Wow!!! Amazing! Added extra pram cheese on top of veggie layer. I diced my potatoe, yam, carrot, and red pepper in bit size. Did 42 minutes and it was perfect so don't waste time par boiling veggies, just diced into bit sizes. I want more now. This will be made this Easter Sunday for sure!!
    I love this casserole! I do dice the potatoes and carrots a bit smaller than instructed so that they cook as fast as the zucchini, tomatoes, onion, etc. which take less time to soften. A very good casserole and can be assembled ahead of time and put in the oven to finish if you're entertaining or even if you're not! It is definitely company fare but also good for family meals. I love the combo of all the vege's all in one fell swoop! 
    Delicious! so easy to make. I will make it again!
    Very Good veggie dish! After reading some of the reviews I made sure to cut the potatoes very thin, scallop thin. Also it's important to cut all the veggies about the same size. That way they get cooked evenly. 
    My husband and I enjoyed it. Going to give the rest to my parents and it's a good dish for my diabetic father.  
    Thanks again Giada!
    This received RAVE reviews from our Italian American Ladies organization pot luck dinner. My only modifications,included Italian seasonings with the salt and pepper and with the bread crumb & cheese, again Italian seasons and garlic!
    Will make again - grazie Giada
    Absolutely wonderful! Most of my family avoid vegetables but they devoured this dish. I look forward to making it again.
    This was delicious! I substituded butternut squash for the yam and it turned out great! My husband loved it also. I will definitely make this again.
    good way to use up extra veggies...I agree with other viewers that the root vegtables need to be either parboiled or pre-baked before assembling the dish....and/or carmelize the onions.
    This is very good! I replaced most of the olive oil with non-stick cooking spray to lower the fat and calories, other than that I followed to recipe exactly. Very healthy and easy to make.
    Yum! This is a great staple for your winter menus! The vegetables all come out cooked perfectly and the crunch of the bread crumbs add a nice texture.
    To die for every single time I make it! It is phenomonal just as is, but I usually add an extra layer (or more sometimes of the tomatoes because that is my favorite part!
    The prep can take longer than 15 mins if you are not a super swift chopper, as I am not, but is beyond worth the wait.
    Even people who would normally turn their nose up at the mere mention of "Vegetable Casserole" will love this. The flavors are just awesome!
    Delicious! Did not change a thing and my hubby and I loved it.
    Didn't change one thing in this recipe. Simply put, it's excellent.
    Very good but it took much longer than 40 minutes to cook. I also had to add some liquid to it to help it cook. I probably cooked it for an hour at 450 and it still wasn't completely done. Will make again but start it earlier.
    All I can say is WOW. I am not a veggie eater unless it is covered in a thick fattening sauce, so I basically avoid vegetables. This is awesome. Great flavor, easy to make and a nice variety of vegetables. I was skeptical that a recipe can get a 5 star rating from so many people. Now I know why. If you're reading this and haven't tried it....try will NOT be disappointed.
    FANTASTIC! My favorite is to use the leftovers the next day in a scramble for breakfast. Simply heat up leftovers in a skillet for a few minutes, add eggs, and scramble together. Delicious with fruit and bread for brunch.
    Smell great cooking, tasted good, and very easy. Personally, my wife loved it but I thought it could have used a few more spices.
    This was SOOOOO Yummy! I love to find new ways to cook all kinds of vegetables, because I LOVE my veggies, and this is my new favorite dish. I absolutely loved it. I did pre-bake my potatoes and carrots for 20 minutes before I added the rest of the ingredients. Just to soften them. And the Parmesan....OMG! Delish! Next time I will sprinkle some parmesan on the bottom layer to get the parm flavor all throughout the dish. I highly recommend, you won't be dissapointed. *** I also put foil down for easy cleanup :)
    Our family and a dinner guest I loved it. We made a substitution (shitake and crimini mushrooms instead of zucchini) only because I forgot to buy the zucchini,but we still found everything blended well and offered max flavor.
    this is wonderful! Second time I made, softened carrots in water/microwave for a minute prior to putting together. Served for company - no leftovers!
    just perfect. 40 min and ready
