Unstuffed Pepper Casserole

This Unstuffed Pepper Casserole replicates the flavors of stuffed peppers without the hassle of filling individual peppers. It combines roasted bell peppers, onions, mushrooms, and a mix of rice and vegetarian grounds baked in a tomato-rich broth and seasoned with Italian herbs and Worcestershire sauce. A crunchy breadcrumb and vegan cheese topping adds texture and richness to the dish.

Description

Unstuffed Pepper Casserole uses red and green bell peppers, onions, and mushrooms roasted first to develop flavor and texture. The vegetables are combined with soaked white rice, a tomato puree base, vegetarian grounds or cooked legumes, and vegan parmesan cheese. The mixture is seasoned with Italian herbs and red pepper flakes and cooked covered in the oven to allow the rice to absorb the savory tomato broth and meld with the vegetables. A topping of vegan breadcrumbs and mozzarella, drizzled with olive oil and sprinkled with red pepper flakes, is baked on at the end to provide a golden, crispy crust.

The casserole offers a rich, satisfying texture that echoes the classic stuffed pepper filling but is easier and faster to prepare. It fits well as a hearty main dish for a vegetarian meal. The recipe includes options for gluten-free and soy-free adaptations by adjusting breadcrumbs, Worcestershire sauce, and vegetarian ground choices.

Storage instructions suggest refrigerating in a closed container for up to 3 days and freezing for longer preservation. Reheating can be done in the microwave or by baking to restore the crisp topping. Using precooked brown rice is an option by adjusting added liquid and baking time, allowing more flexibility.

  • 1/2 teaspoon salt
  • 4 ounces tomato puree canned
  • 1/2 cup tomato chopped
  • 1 1/2 cups water or veggie stock. Not necessarily boiling, but it should be hot, hot
  • 3/4 cup white rice washed, soaked for 5 minutes, and then drained ( I use Indian basmati)
  • 3/4 cup vegetarian grounds or use 3/4 cup of cooked lentils, chickpeas, or other beans
  • 1/4 cup vegan parmesan cheese

  • 1/2 cup vegan mozzarella or a mix of vegan mozzarella and vegan parmesan
  • salt generous pinches
  • red pepper flakes generous pinches
  • 1 teaspoon olive oil

Instructions

Make the peppers.

  1. Preheat the oven to 415° F (213° C).
  2. Chop the veggies, if you haven't already, then add the oil to an 8 1/2” x 10 1/2” or similar-sized baking dish.
  3. Add the onion, garlic, bell peppers, mushrooms. Sprinkle the salt, and pepper and toss well to coat. Bake for 15 -20 minutes, so that some of the peppers can start to sear.

Meanwhile prepare the rest of the casserole.

  1. Wash the rice and soak for 5 minutes, if you haven't already, then remove the baking dish from the oven, mix in the Italian herbs, Worcestershire sauce, salt, tomato puree, and tomato.
  2. Mix in the hot water or stock, then mix in the rice, the veggie grounds, and vegan parmesan. Even out the top, then cover the dish with parchment paper, and bake for another 20 to 25 minutes. Check at the 20-minute mark. If the rice is done, then remove it from the oven. The rice should be just al dente, because we're going to put it back into the oven with the topping, and you don't want the rice to overcook.

Make the topping while the casserole bakes.

  1. In a bowl, mix the breadcrumbs, vegan mozzarella, salt, and pepper flakes, and sprinkle this all over the casserole. Drizzle the olive oil all over the top, and then bake for 2 to 3 three more minutes.
  2. Broil for a minute to brown(optional) and then remove the casserole dish from the oven. Garnish with some fresh herbs and serve with toasted sourdough or top it with salsa or hot sauce. You can also add unstuffed peppers to tacos, burrito or wraps or serve it however else you like.

Notes

  • To make gluten-free, use gluten-free breadcrumbs and soy-free Worcestershire sauce or tamari for soy-free or nut-free versions.
  • Store leftovers in a closed container in the refrigerator for up to 3 days or freeze for longer storage; reheat in the microwave or oven.
  • If using brown rice, add only 1/4 cup water or stock and top with the breadcrumb mixture before baking briefly to finish.
