Who doesn’t love stuffed peppers? It’s old school comfort food at it’s best. It’s a weeknight family meal that’s simple to make with flavorful fillings packed into a rainbow colored edible vessel. They can be stuffed with starches, meats, cheese, beans or all veggies showcasing even different ethnic cuisines.

Needless to say the combinations are endless and for that reason stuffed peppers will be around for a long long time.

I love using an assortment of rainbow colored bell peppers, they still maintain their color and sweetness after baking, and the different colors make for a pretty presentation.

Cutting the peppers lengthwise allows for more of the filling to be packed into them. These peppers are packed tightly with Italian sausage, onions, garlic, mushrooms, chopped kale and I swapped out of white rice ( which you don’t even miss) for healthier cauliflower rice.

Of course some cheese is involved along with marinara which gives these stuffed rainbow colored peppers a delicious depth of flavor with a nice Italian twist!

Did I mention how good the leftovers are? Be sure to make enough so you can heat one up for lunch the next day you’ll be happy you did.

Stuffed Rainbow Colored Peppers with Cauliflower Rice and Italian Sausage
  • 4 rainbow colored bell peppers, cut lengthwise in half, then scoop out seeds and membrane
  • 1 lb. Italian sausage, casings removed and crumbled into small pieces
  • 2 cups frozen or fresh chopped riced cauliflower
  • 1 onion diced
  • 4 cloves garlic, finely chopped
  • 1 handful kale or spinach, chopped
  • 6 large cremini mushrooms chopped
  • a handful of cherry or grape tomatoes, sliced
  • ¾ cup shredded mozzarella plus a little extra for garnishing the tops
  • ½ cup of grated pecorino
  • ½ cup marinara sauce for the filling and enough extra sauce to cover the bottom of a 9x12 baking dish
  • salt and pepper to taste
  • 1 tablespoon each, chopped basil and parsley
  1. Heat oven to 375
  2. Oil the bottom and sides of a 9x12 baking dish.
  3. Pour enough marinara sauce on the bottom of the baking dish to cover it all over.
  4. Place the 8 raw halves of the peppers into the baking dish.
  5. Brown the crumbled sausage in a pan until you see no pink at all, then remove and drain on paper towels.
  6. Wipe out pan of excess grease then add the onion, garlic and chopped mushrooms, riced cauliflower and cook til slightly soft then toss around and add the chopped kale to let it wilt.
  7. In a bowl add the drained sausage, cauliflower, cooked onion, garlic, mushrooms, kale, grated cheese, mozzarella, the sliced cherry tomatoes and the ½ cup of marinara sauce and herbs tossing well to incorporate everything.
  8. Fill each raw pepper with the filling, packing it in.
  9. Cover pan with foil and bake for 30 minutes then remove pan and change oven temp to 400
  10. Take the foil off, sprinkle the tops with a tablespoon or 2 of shredded mozzarella and some grated cheese.
  11. There will be a lot of moisture at the bottom of the pan from the foil being on but the higher temp will reduce it all.
  12. It's finished when you can say the peppers are nice and tender , test with the tip of a sharp knife and cheese is a little golden.
  13. Spoon some sauce on top of each and serve.

    HI Marie!
    These look and sound incredible!! Cant wait to give these a try! Love using the cauliflower instead of rice

    Marie, what a fabulous recipe! My husband, and I loved every bite. I had to improvise a little, didn’t have cauliflower rice, couldn’t get out of my driveway to go to the store to get it. I used Trader Joe’s multigrain rice and vegetables in place of it. So delicious, and satisfying. The good thing is we have enough leftovers for dinner tomorrow. Thank you so much 😊

  5. Marie, I really like your idea of using the cauliflower rice in your stuffed peppers.

  6. This looks absolutely amazing! Can’t wait to make it-

  7. Sounds absolutely wonderful!! A perfect dish for a colorless winter day. I could eat that for lunch or dinner. With Hubby I’d have to add farro, quinoa, or freekeh to give it bulk. I’m make mine just like you did. So beautiful and colorful — great photos of a delicious dish.

    i might have glazed over ( most likely!) but when do you incorporate the riced cauliflower?
