You can enjoy all the flavors of stuffed peppers without going through all the worked of making stuffed peppers by whipping together this easy, hearty lightened up stuffed pepper casserole!
With the passing of Labor Day weekend, people seem to be in two different groups. One group is hanging on to all things summer as hard as they can and one group is charging into all things fall! Whatever group you’re in, I think we can agree on one thing. Comfort food is good.
Quick and easy comfort food is better. Quick and easy comfort food that is healthy (while still tasting good!) is best! One dish that fits all of those requirements is this lightened up stuffed pepper casserole.
Warm, hearty comfort food is always a favorite around here, so I figured it was about time that I lightened up one of our favorites. Stuffed pepper casserole is super easy is to make, can be made ahead of time, and can be switched up to meet everyone’s tastes.
What’s not to like?! It wasn’t hard to give this dish a nutritious makeover while keeping the taste we loved.
Lean ground beef or turkey breast keeps the protein light. Using fresh tomatoes, peppers, onions, and garlic gives the casserole a boost of nutrients.
And for the rice? Make the simple swap of brown rice for white rice. No one will even notice and you’ll get all of the benefits of whole grains instead of refined white rice.
A dish that can be a favorite for both summer and fall lovers!

This recipe is one of my absolute fav! I can eat this everyday that’s how much I love this! Thank you for sharing this. Keep the recipes coming! 🙂

We’ve made this multiple time, we use less cheese and beef up the veggies. We use ground chicken and top with panko breadcrumbs.
This is a winner for even the pickiest eaters. So filling! Very good recipe and super easy to make!
Elicea says
I wanted to make this for my dad, but he is on a liquid restriction plan. Is there something I can do that will use less liquid than pasta sauce? Would tomato paste work as well? I figure that the moisture will cook out of that quite a bit…
Cara says
So happy I found this recipe – I’ll definitely make again.
I swapped the brown rice for cauliflower rice and added Italian seasoning.
Next time I may add mushrooms and some fresh herbs.
Easy, healthy & delicious!
