Prep: 20 minCook: 4 hrTotal: 4 hr 20 minServes: 6
Ingredients
- 1 1/2 lb bulk sweet Italian sausage
- 6 large bell peppers, halved lengthwise and cored
- 1 1/2 cups cooked white or brown rice
- 1/2 cup sun-dried tomatoes in oil, drained and chopped
- 2 cups fresh baby spinach, coarsely chopped
- 1 cup marinara sauce, divided
- 1 1/2 cups shredded mozzarella cheese
- 2 cloves garlic, minced
- 1 tsp dried Italian seasoning
- 1/2 tsp salt
- 1/4 tsp crushed red pepper flakes
Instructions
- Pour 1/2 cup of marinara sauce into the bottom of a 6-quart crockpot slow cooker.
- In a large bowl, combine the uncooked bulk Italian sausage, cooked rice, chopped sun-dried tomatoes, chopped baby spinach, minced garlic, Italian seasoning, salt, crushed red pepper flakes, and the remaining 1/2 cup of marinara sauce. Mix until thoroughly combined.
- Spoon the sausage mixture evenly into each hollowed bell pepper half, pressing gently to pack the filling.
- Arrange the stuffed pepper halves upright in the slow cooker, nesting them closely so they remain upright.
- Cover and cook on LOW for 3 1/2 to 4 hours (or HIGH for 2 to 2 1/2 hours) until the pepper shells are fork-tender and the internal temperature of the meat filling reaches 160 F on a meat thermometer.
- Sprinkle shredded mozzarella cheese evenly over the top of each pepper, cover, and let cook for an additional 10 minutes until melted and bubbly before serving.
Tips
- To prevent soggy peppers, place a clean paper towel directly under the slow cooker lid during the final 30 minutes of cooking to absorb excess condensation.
- You can assemble the stuffed raw peppers in the insert, cover, and refrigerate overnight, then pop the insert into the crockpot base in the morning.
- Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat gently in the microwave or oven.
