There was a year when my garden was overflowing with zucchini. It was a zucchini avalanche! Since I’m never one to waste food, I tried just about every sweet and savory way to cook it up. This recipe managed to stay in my annual summer recipe rotation long after I finished my zucchini bumper crop.
Recipe type: Entree
Cuisine: American
Serves: 6 servings
  • 3 medium zucchini, halved lengthwise and thinly sliced
  • 3 large russet potatoes, halved lengthwise and thinly sliced
  • ¾ cup diced green or red bell pepper (about 1 small bell pepper)
  • ¾ cup nutritional yeast
  • 1½ teaspoons minced garlic (about 3 small cloves)
  • ¾ cup diced red, white, or yellow onion (about 1 small onion)
  • ½ cup dry bread crumbs (gluten-free, if needed)
  • ¼ cup olive oil
  • Salt, to taste
  • Black pepper, to taste
Optional Additions
  • 1 teaspoon red chili flakes added in step 2
  • Pinch paprika added in step 2
  1. Preheat the oven to 400 degrees F.
  2. In a large bowl, combine all the ingredients.
  3. Transfer the potato and zucchini mixture to a large casserole dish.
  4. Bake for 30 minutes, mix the casserole, and then bake for another 30 minutes. Keep an eye on it for the last 10 minutes to prevent burning.
TONI’S TIPS: If you notice the casserole is getting charred on the top, you can take it out, cover it with aluminum foil, and put it back in the oven for the remaining time.
TESTERS’ TIPS: “For added flavor, use Italian-style bread crumbs. Also, sliced mushrooms would be a nice addition for texture and flavor.” —Kathryn H. from Concord, CA

  1. This recipe is just delicious. I had to do some tweaks because of what I had on hand. I did 4 potatoes, one zucchini, 3 carrots & a large shallot. I didn’t have bread crumbs so I put rolled oats in. Didn’t know what that would do but it was so good. I will be making this again! So many options to use up vegetables before they go past their prime. Thanks!

    • It adds cheesy flavor, and there is a lot of it in this dish. So if you leave it out, it will be a different dish, and you will probably need to add some other flavors, adjust ingredient ratios, etc.

    • If you have any type of bread on hand or in the freezer (loaves, bagels, buns, etc) you can turn that into breadcrumbs. If not, you can try crushed chips, ground nuts, crushed crackers, or crushed cereal.

  2. Are you not seeing step 2 for some reason on your view? I’m seeing it here. We haven’t altered the recipe. It looks like an error in the cook time noted at top – I’ve fixed that. It looks like the breadcrumbs are stirred in, not used for topping. But you can try that if preferred. If so, then you’ll want to top with the crumbs after you remove and stir the casserole – otherwise you will just be stirring them back in.

    Where is step two? Does the nooch get mixed in with potatoes or go in step two? I’m guessing the bread crumbs go on top? this takes one hour to cook in the beginning of listing it says 30 minutes?
