Servings: 6 peppers
Calories: 416kcal


  • 1 tablespoon olive oil
  • 1 pound ground beef
  • 4 cups cauliflower rice
  • 1 clove garlic * minced
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 15 ounces tomato sauce * I prefer Rao's for less carbs and sugar
  • 1 teaspoon Italian seasoning
  • 6 bell peppers * any color, tops and seeds removed
  • 6 ounces mozzarella * fresh


  • Preheat oven to 350°F.
  • Add the olive oil to a large skillet over medium high heat.
  • Add the ground beef, cauliflower rice, and garlic. Season with salt and pepper.
  • Cook, stirring occasionally, until the beef is brown and no longer pink, about 5-7 minutes.
  • While the beef and cauliflower are cooking, mix together the tomato sauce and Italian seasoning in a bowl.
  • Add half of the sauce to the ground beef and cauliflower. Mix thoroughly.
  • Spoon the beef mixture evenly into the prepared peppers and place upright in a casserole dish.
  • Pour the remaining sauce over the tops of the stuffed peppers.
  • Cover and bake, basting occasionally, until the peppers are tender - about an hour.
  • Uncover and top evenly with the mozzarella cheese. Bake an additional 3-5 minutes until the cheese is melted and browned (you can also use the broiler for 1-2 minutes, watching closely).


Tips and Techniques for the Best Keto Stuffed Peppers

  • You can use any combination of peppers you prefer – green, red, orange, and yellow bell peppers are usually larger and easiest to fill.
  • You can reference this post on How to Rice Cauliflower, if needed or use pre-rice cauliflower from the produce or frozen food section of the grocery store.
  • It is NOT recommended to use pre-shredded mozzarella. It typically doesn't melt as nicely due to the additives to prevent it from sticking together in the package.
  • Store leftovers in an air-tight container in the refrigerator. Use within 3-5 days.
** Nutritional information is an estimate and may vary. Calculations were made using Rao's Marinara Sauce. Other brands or plain tomato sauce may increase the total net carbs and sugar content.
