For pretty much as long as I can remember, I’ve loved stuffed peppers, and my family can make some of the best traditional stuffed peppers, if I do say so myself.

But like most people, I don’t often have the time to actually stuff peppers, prepping the bell peppers, making the rice mixture, then baking it. I don’t mind putting in the extra effort in the kitchen, but I can admit I didn’t and don’t usually have the time to make traditional stuffed peppers.

So, as I often do, I set out to find a way to turn one of my favorite comfort foods into a quick, simple, filling, and delicious home-cooked meal that takes hardly any time to make. And can easily be tossed together on any given night.  

In all fairness, I probably should have called this unstuffed pepper casserole, but for some reason, that name just never stuck. So while the title might be a little incorrect, I can promise that is recipe is super easy to make, tastes amazing, and is sure to be a hit with everyone, even picky eaters.

  • onion, diced
  • Italian seasoning 
  • sea salt
  • freshly ground black pepper
  • fresh garlic, minced

Directions

In a large pot, Dutch oven, or deep skillet, brown your ground beef with your diced onion over medium-high heat. Once the beef is cooked through drain off and discard any excess grease. 

Add the minced garlic and diced pepper bells and cook until the garlic is fragrant and the peppers are soft. about 5 minutes. Add the Italian seasoning, salt, and pepper, and stir to combine. 

Then add the tomato sauce and diced tomatoes, and stir. Add the soy sauce(or Worcestershire sauce) and the beef broth. 

Bring the mixture to a boil, stirring often. Once the mixture is boiling, add the rice, stir, and reduce the heat, to medium-low.

Allow the mixture to simmer, stirring occasionally, until the rice is completely cooked and has soaked up most of the liquid in the pan. About 15 minutes. Remove the pan from the heat and add 1 1/2 cups of the shredded cheese, and stir until the cheese is completely melted. 

Now, there are a couple of ways to finish your casserole. You can either sprinkle the remaining cheese over your rice mixture. Cover and allow the cheese to melt, about 1 minute, and serve.

Or you can transfer your rice mixture to a casserole dish, sprinkle your remaining cheese over the top, and pop your casserole into the oven. I love doing this, as it makes the cheese perfectly melted and golden brown. But you can easily do whatever works best for you!

Serve and enjoy!

Recipe Notes

Any leftover casserole can be stored in an airtight container or covered with aluminum foil and kept in the fridge for up to 5 days! Stuffed pepper casserole can easily be reheated in the oven or on the stovetop!

I usually serve this recipe on its own, but also great with a side salad, and/or a slice of garlic bread.
