Turkey and cauliflower rice stuffed peppers answer the usual stuffed-pepper problem: how to get tender peppers and a hearty filling without cooked rice. Roasting the pepper halves briefly first softens them, and cooking excess moisture out of the cauliflower rice keeps the filling from turning soupy.
The filling is savory rather than spicy: browned ground turkey, tomatoes, onion, garlic, and Italian seasoning, finished with a little mozzarella. Four large peppers make eight halves, enough for four generous servings. Choose peppers that are similar in size so they finish at about the same time.

Prep: 20 minutes Cook: 40 minutes Total: 1 hour Yield: 4 servings (2 pepper halves each)
Ingredients
- 4 large bell peppers, any colors, halved lengthwise and seeded
- 1 tablespoon olive oil, divided
- 1 small yellow onion, finely chopped
- 1 pound 93% lean ground turkey
- 3 garlic cloves, minced
- 12 ounces frozen cauliflower rice, thawed and squeezed or drained well
- 1 can (14.5 ounces) diced tomatoes, drained
- 2 tablespoons tomato paste
- 1 teaspoon dried Italian seasoning
- 1/2 teaspoon fine salt
- 1/4 teaspoon black pepper
- 3/4 cup shredded part-skim mozzarella
- 2 tablespoons chopped parsley, optional
Directions
- Heat the oven to 400°F. Lightly oil a 9-by-13-inch baking dish. Arrange the pepper halves cut-side up, brush with 1 teaspoon of the olive oil, and roast for 10 minutes while you prepare the filling.
- Heat the remaining olive oil in a large skillet over medium heat. Cook the onion for 3 minutes. Add the ground turkey and break it apart; cook for 6 to 8 minutes until no pink remains and the thickest pieces reach 165°F on an instant-read thermometer.
- Stir in the garlic and cook for 30 seconds. Add the well-drained cauliflower rice and cook uncovered for 4 minutes, stirring, until excess moisture evaporates.
- Stir in drained tomatoes, tomato paste, Italian seasoning, salt, and pepper. Cook for 2 minutes until the filling is cohesive rather than watery. Taste and adjust seasoning.
- Spoon the filling evenly into the eight warm pepper halves. Cover the dish tightly with foil and bake for 15 minutes. Remove foil, sprinkle mozzarella over each half, and bake uncovered for 5 more minutes until the cheese melts and peppers are tender.
- Rest for 5 minutes before serving. Sprinkle with parsley if using. Check that the turkey filling is still hot throughout; leftovers must be reheated to 165°F.
Why this recipe works
A head start for the peppers. Brief roasting gives the shells time to soften while the turkey cooks on the stove.
Less liquid means better filling. Thawed cauliflower rice and canned tomatoes both hold water. Draining and cooking them uncovered prevents a puddle in the baking dish.
Helpful variations
Use a dairy-free cheese alternative or leave off the mozzarella. For a smoky flavor, replace the Italian seasoning with 1 teaspoon chili powder and 1/2 teaspoon ground cumin, then serve with lime. To make the meal more substantial without relying on rice, add 1 cup of chopped mushrooms with the onion and cook until their liquid evaporates. Regular cooked rice can replace cauliflower rice, but that changes the lower-carb intent and nutrition estimate.
Common questions
Can I use fresh cauliflower rice? Yes. Use about 3 cups and cook it in the skillet until dry before adding tomatoes; you do not need to thaw it.
Can these be made ahead? Cook the filling and roast the peppers, then chill them separately for up to 1 day. Assemble and bake from the refrigerator, allowing a few extra minutes until hot throughout.
How do I keep the peppers upright? Cut lengthwise through the stem if possible and nestle the halves against one another in the dish. A small trim on the rounded underside helps if a pepper wobbles.
Storage and food safety
Refrigerate stuffed peppers in shallow airtight containers within 2 hours and use within 3 to 4 days. Reheat in a covered baking dish at 350°F or in the microwave until the center reaches 165°F. Freeze well-wrapped portions up to 2 months for best texture; thaw overnight in the refrigerator. Ground poultry needs to reach 165°F during initial cooking. See USDA leftover guidance.
