Stuffed pepper casserole is one of those weeknight dinners that checks every box: one pan, big flavor, and zero complaints at the table. It brings together bell peppers, seasoned ground meat, rice, and melted cheese in a single skillet that practically cleans itself.
The first time I threw this together on a Tuesday with nothing but pantry staples, I had no idea it would become the most requested dinner in my house. My kids scraped the skillet clean, and I had three texts by the end of the week asking for the recipe.
What makes this stuffed pepper casserole so special is that the rice cooks right in the pan, soaking up all that savory tomato sauce and Italian seasoning as it simmers. No pre-cooking, no extra dishes, no stress. Just one pan and a hot stove.

Ingredients for Stuffed Pepper Casserole
These are simple, everyday ingredients you likely already have on hand. I always keep canned tomatoes, rice, and Italian seasoning stocked in my pantry just for this recipe. Here is everything you need to make a full skillet that serves six.
- 1 tbsp olive oil
- 1 cup yellow onion, chopped
- 1 red bell pepper, chopped – I recommend using a firm, bright red pepper for the best sweetness
- 1 green bell pepper, chopped
- 1 lb ground turkey or ground beef – my preference is ground turkey to keep things lighter, but both work great
- 3 cloves garlic, minced
- 15 oz can petite diced tomatoes – in my experience, petite diced blends in more evenly than regular cut
- 8 oz can tomato sauce (about 3/4 cup)
- 2 tsp Italian seasoning
- 1/2 tsp garlic powder
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 1/2 cups water
- 1 cup long grain white rice, rinsed and drained – I always rinse to remove excess starch and prevent clumping
- 1 cup shredded cheddar, mozzarella, or a mix (about 4 oz), divided
- 2 tbsp fresh parsley, chopped, optional for serving
Step-by-Step Instructions
I recommend having all your ingredients prepped before you turn on the stove. In my experience, this stuffed pepper casserole comes together fast once you start cooking, so being ready makes a real difference.
Step 1: Heat olive oil in a large skillet over medium-high heat. Add the chopped onion, bell peppers, and ground turkey or beef. Cook for 6 to 8 minutes, breaking up the meat as it browns. If you are using ground beef and there is excess grease in the pan, drain it off before moving to the next step. Stir in the minced garlic and cook for 30 seconds until fragrant.
Step 2: Stir in the diced tomatoes, tomato sauce, Italian seasoning, garlic powder, salt, pepper, water, and rinsed rice. Mix everything together well and bring to a simmer. Reduce the heat to maintain a low simmer, cover the skillet with a lid, and cook for about 15 minutes. Stir every 5 minutes to keep the rice from sticking to the bottom of the pan. The rice is done when it is tender and has absorbed most of the liquid.
Step 3: Remove the lid and stir in 1/2 cup of the shredded cheese until it melts into the casserole. Sprinkle the remaining 1/2 cup evenly over the top of the skillet.
Step 4: Cover the skillet again and let it rest off the heat for 5 minutes. This resting time allows the cheese on top to melt fully without overcooking the rice. Sprinkle with fresh parsley if using and serve straight from the skillet. Pro tip: if the rice looks slightly underdone after 15 minutes, add 2 to 3 tablespoons of water, cover, and cook for 3 more minutes before checking again.

Roasted Broccoli: Caramelized roasted broccoli florets pair naturally with the Italian-seasoned tomato base and bring in a nutritious boost that rounds out the dinner plate.
How to Store and Reheat Stuffed Pepper Casserole
Store any leftover stuffed pepper casserole in an airtight container in the refrigerator for up to 4 days. Let it cool completely before sealing the container to keep the texture of the rice from getting mushy.

To reheat, add a splash of water or chicken broth to the portion before microwaving covered for 1 to 2 minutes, stirring halfway through. On the stovetop, warm it over low heat with a lid on, adding a small splash of water and stirring gently every couple of minutes.
Pro tip: this casserole actually tastes better the next day as the flavors deepen overnight. You can also freeze individual portions in sealed containers for up to 2 months. Thaw in the refrigerator overnight before reheating.

FAQs
Can I use brown rice instead of long grain white rice? No. The cook time and water ratio in this recipe are set specifically for long grain white rice. Brown rice requires more water and a longer cook time, which would throw off the whole dish. Stick with long grain white rice for best results.
Can I make this stuffed pepper casserole ahead of time? Yes. You can cook it fully, let it cool, and store it in the refrigerator for up to 4 days. Reheat with a splash of water to bring it back to the right texture. It actually tastes great the next day.
What is the best meat to use in this recipe? Both ground turkey and ground beef work well. Ground turkey keeps it lighter, while ground beef adds a richer, bolder flavor. Use whichever your family prefers or whatever you have on hand.

- Stir in the diced tomatoes, tomato sauce, Italian seasoning, garlic powder, salt, pepper, water, and rinsed rice. Mix well and bring to a simmer. Reduce heat to maintain a low simmer, cover the skillet, and cook for about 15 minutes, stirring every 5 minutes to prevent the rice from sticking. Rice is done when tender and most of the liquid is absorbed.
- Stir in 1/2 cup of the shredded cheese until melted. Sprinkle the remaining 1/2 cup evenly over the top of the skillet.
- Cover the skillet and let rest off the heat for 5 minutes to melt the top layer of cheese. Sprinkle with fresh parsley if desired and serve directly from the skillet. If rice appears slightly underdone, add 2 to 3 tablespoons of water, cover, and cook for an additional 3 minutes before resting.
