  • ½ tsp. fennel seeds

How to Make Slow Cooker Unstuffed Peppers

Lots of slow cooker recipes start by having you brown the meat and onions with seasoning in a skillet first. This helps you develop some flavor before letting the ingredients simmer in a slow cooker for hours. That's how this one works, too. Once the ground turkey and onion have been browned and combined with the seasonings, they're transferred to the slow cooker along with the bell peppers, rice (uncooked), tomato sauce, chicken broth, and garlic powder. Then you set it on high for 3 to 4 hours, and you're good to go.

How to Store and Serve Slow Cooker Unstuffed Peppers

These are great for meal prepping because you can just store everything in simple single-ingredient containers; no need for little compartments. This dish has all the food groups in one meal! Make sure it's airtight, and keep it in the fridge for 4 to 5 days. You can also really easily freeze this recipe. Just defrost it overnight in the fridge and reheat, or pop it in the microwave, or in a saucepan on a stovetop. Make sure it's totally hot!

This unstuffed peppers recipe is also great with a green salad with a red wine vinaigrette and a loaf of crusty bread. It doesn't really need much though.

Substitutions and Alterations

Use any combination of bell peppers you want here; it will be nice and colorful.

Use brown rice or white rice; either will work. Normally, we love cauliflower rice and recommend it as a swap, but in this case, it will get soggy very fast, so we don't advise that. You could, however, cook it separately and mix it in, once the rest of the unstuffed peppers are ready.

Feel free to substitute ground chicken, beef, or pork with this recipe, instead of the turkey.

If your slow cooker is big enough, you can easily double this recipe and freeze it for a future date. Just leave the cheese off if you're planning to freeze.

We like to brighten this up with a sprinkling of freshly chopped parsley.
