Slow cooker stuffed peppers are a fantastic dish that you can prepare early in the day and have them ready for when you sit down for dinner.

Slow Cooker Stuffed Peppers

There are so many variations on stuffed peppers as it’s effortless to change the recipe to suit your taste buds. Just make sure you don’t add too many wet ingredients otherwise the filling will become sloppy.

You can cook these stuffed peppers in either some marinara sauce or in beef stock. Both will impart a unique flavor to your peppers. Personally, I prefer tomato-based sauce, so I tend to use marinara sauce.

Towards the end, I topped the peppers with a bit of cheese. This addition of cheese not only makes it look appealing but also adds that lovely cheesy texture and flavor. I use cheddar cheese, but mozzarella or even parmesan will work great too.

These slow cooker stuffed peppers are great just on their own and won’t require any extras. Out of a single batch of this recipe, you will feed about four to six people. If you want some extra sides to go with it then something like rice, a salad, or even potato mash will go great with this dish.

Stuffed Peppers

I haven’t been able to test how these will reheat after freezing however it’s unlikely they will heat great. Leftovers kept in the fridge are still decent enough to enjoy once heated. Discard after a couple of days in the refrigerator.

Cooking Tips

  • It’s important to use lean ground beef as you don’t want too much fat in the slow cooker. If you can’t get your hands on some lean ground beef, then brown and drain it before mixing with the other ingredients.
  • Using uncooked rice in the beef mixture may lead to the rice not cooking correctly. Uncooked rice will be hard and not appetising at all.
  • When you pour in the beef stock or marinara sauce, make sure you don't get any inside the bell peppers. It can make them get very sloppy.
