How to Make Slow Cooker Sausage Stuffed Peppers

Step 1: Prepare the Peppers

Wash the bell peppers and slice them in half lengthwise. Remove the seeds and membranes from the inside.

Using halved peppers helps them fit neatly into the slow cooker and cook more evenly.

Step 2: Cook the Sausage Filling

In a skillet over medium heat, cook the Italian sausage until browned. Break it into crumbles while cooking.

Add the diced onion and garlic, cooking until softened and fragrant.

Drain excess grease if necessary.

Step 3: Mix the Filling

In a large bowl, combine:

• Cooked sausage mixture
• Cooked rice
• Diced tomatoes
• Italian seasoning
• Half the mozzarella cheese
• Parmesan cheese

Mix well until fully combined.

Step 4: Stuff the Pepper Halves

Spoon the sausage filling evenly into each pepper half.

Arrange the stuffed peppers inside the slow cooker in a single layer if possible.

Pour marinara sauce around and slightly over the peppers to keep everything moist during cooking.

Step 5: Slow Cook

Cover and cook:

• On LOW for 5–6 hours
  or
• On HIGH for 2½–3 hours

The peppers should become tender while still holding their shape.

Step 6: Add Cheese

During the final 15 minutes of cooking, sprinkle the remaining mozzarella cheese over the stuffed peppers.

Cover again until the cheese melts into a bubbly, delicious topping.

Tips for the Best Stuffed Peppers

Choose Firm Peppers

Fresh, firm bell peppers hold up best during slow cooking.

Pre-Cook the Rice

Cooked rice blends better into the filling and absorbs flavor without becoming mushy.

Use Mild or Spicy Sausage

Customize the heat level depending on your preference.

Don’t Overfill the Slow Cooker

Arrange the peppers carefully so they cook evenly and stay intact.

Delicious Variations

Low-Carb Stuffed Peppers

Replace rice with cauliflower rice for a lighter version.

Mexican-Inspired Version

Extra Cheesy Peppers
