Love stuffed peppers like I do? This hearty casserole dish takes all the flavors you love about stuffed peppers but without all the messy prep! Hearty meal-prep or perfect dish for the whole family, either way your can't go wrong with this meaty casserole!
This dish really is a complete meal with all of the vegetables. I like to finish off the meal with a keto chocolate chip cookie or almond butter cookie!

I love the flavor of stuffed peppers but they require a lot of work and the ratio of pepper to meat is just too much pepper. I love how this casserole is full of protein but still has lots of veggies.
This recipe really couldn't be more simple. I love the combo of the ground beef and the Italian sausage for extra spice.
Recipe Tips and Notes
- You can use any color bell pepper you like. I really like green but sweet bell peppers would also be great.
- Use frozen chopped vegetables to make this recipe even easier.
- Divide this unstuffed pepper casserole into meal prep containers for easy meal prep

Made this tonight - YUMMY and filling!! Used ground chicken and chicken sausage for the meats. Added an extra green pepper (from other reviews) and added a bit of leftover spinach. Because chicken needs a bit more "Umph" than beef, I also added some paprika (based on other reviews), basil and doubled the oregano & Worcestershire. Made an extra one from this recipe and now have one if the freezer for another day - it's a win-win! SO happy I found your recipe because it was almost impossible to find stuffed peppers without rice. THANK YOU!

Normally when I make stuffed bell peppers, the kids just eat the filling and leave the pepper. Made this and kids ate everything on their plate and asked for seconds. The only thing I changed was adding one more bell pepper (I did one of each color) and I used a little less cheese. This will be added to my regular rotation!
