Slow Cooker Stuffed Peppers

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

By the end of cooking, you will have a deliciously tender bell pepper that’s loaded with a ground beef filling. The filling is packed with ingredients that have a ton of flavors such as herbs, sauces, onion, cheese, and more.

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.

How to Serve these Stuffed Peppers

These slow cooker stuffed peppers are great 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. However, if you want to do a little extra to go with these peppers, then there are a few suggestions below.

Towards the end, I top 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.

If you want some extra sides to go with these peppers, then something like rice, a salad, or even potato mash will go great with this dish. There are a lot of great options, but I prefer eating these without any accompaniments

Perfecting this Recipe

Picking the best peppers for stuffing is a little more difficult than you might think. The ideal pepper will have firm sides with little to no blemishes and a flat bottom. If the bottom is pointy, then the peppers will just fall over. You don’t need to be picky when it comes to the color of the bell pepper.

To get the best possible filling, you will need to taste and adjust the seasoning. To do this, simply cook a teaspoon of the beef mixture and taste it. Adjust the seasonings accordingly, and you will get one tasty recipe. However, I think it’s perfect without any changes.

Stuffed Peppers with a Ground Beef Filling

Try to find the best tasting marinara sauce as it will heavily impact the outcome of this dish. I prefer to make it myself, but there are plenty of brands that you’re able to buy. A lot of pizza-style sauces will have lots of flavor from the additional herbs and seasonings.

What to do with Leftovers

I love eating leftovers the next day for lunch or dinner as they make for an incredibly easy meal. I simply reheat the stuffed peppers in the oven or microwave.

I haven’t been able to test how these will reheat after freezing. Unfortunately, it’s unlikely the leftovers will heat great due to the cheese and rice.

Leftovers kept in the fridge are still decent enough to enjoy once heated. Discard after a couple of days in the refrigerator.

Recipe 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 will likely lead to the rice not cooking correctly. Uncooked rice will be hard and not appetizing at all.
  • When you pour in the marinara sauce, make sure you don't get any inside the bell peppers. It can make the insides very sloppy.
  • You can use a pasta sauce or beef stock as a replacement for the marinara sauce.
  • Reduce the cooking time by setting the slow cooker to high. On high, this dish should be ready within three to four hours.

      I haven’t tested it, but I would aim for about 3-4 hours on high.

      About 24 minutes on high pressure should cook the peppers nicely.

    I have made this recipe so many times now! My family loves them!!! We use lean ground turkey and I’ve cooked the peppers in beef stock and the marinara/pasta sauce.
