Keto Stuffed Peppers are simple and delicious and use bell peppers (colours of choice), cauliflower rice, onion, garlic, and beef.


Units Scale

Olive oil (for greasing ovenproof skillet)

4 bell peppers, halved and cored

1/2 pound cooked cauliflower rice* 

2 tablespoons olive oil, divided

1/2 large onion, finely chopped

1/2 cup chopped mushrooms (optional)

24 cloves garlic, minced

1 pound ground beef (grass-fed for Keto Healthy Heart)

1 teaspoon dried oregano

Freshly ground black pepper

1.5 cups no sugar added tomato sauce

1/2 cup freshly grated Parmigiano-Reggiano 

1 1/2 cups shredded partly-skimmed mozzarella 


  • Preheat oven to 400° F (204 C). Grease ovenproof skillet with olive oil. Place eight halved peppers in skillet. Set aside. In a large pot of boiling salted water, cook cauliflower rice until just al dente. Drain and set in a bowl. 
  • In another large skillet over medium heat, heat 1 tablespoon olive oil. Add onion and cook until soft, about 5 minutes. Stir in garlic, then add ground beef, breaking up the meat with a wooden spoon. Cook until no longer pink.  Add tomato sauce. Let simmer 10 minutes, then remove from heat. Let cool.  Fold in cooked cauliflower rice and parmesan.
  • Drizzle peppers with more olive oil and season with pepper.  Fill each half pepper with cauliflower rice/meat sauce mixture. Bake for 25 minutes, until peppers soften and rice/sauce mixture is heated.
  • Remove from the oven. Top peppers with mozzarella. Broil for 5 minutes until cheese is melted. Serve hot.

  • The recipe baking temperature and time is an estimate.  Follow your own oven’s temperature and cooking time. It takes a gas oven 10-15 minutes to reach the desired temperature. Electric ovens can take 10 minutes longer than that.  The age of your oven will also determine the temperature, time for roasting or baking, and where you want to place your dish in the oven.  The bottom of your oven may be hotter than the top, depending on its condition.  This also includes where to set your dish under the broiler.  So use your own best judgment based on the type, condition, and age of your oven.  Prep times will also vary depending on how slow or quickly you like to work.
