There is something endlessly comforting about a stuffed pepper casserole loaded with ground beef tender rice and melty cheese It packs all the flavors of classic stuffed peppers into one easy bubbling dish perfect for busy weeknights or cozy gatherings This has been a top go to when I want a no fuss hearty family dinner that still feels special
I remember making this for the first time on a chilly evening with barely anything in the fridge My husband was skeptical at first but now he requests it every time bell peppers are on sale
Ingredients
- Ground beef: Choose lean ground beef for less grease and cleaner flavor Brown for rich taste
- Bell peppers: Any color works Use two for a natural sweetness and bright color always pick ones that feel firm and heavy for their size
- Onion: Finely chopped for even flavor throughout Yellow or white onions work best look for a tight dry skin
- Garlic: Minced for robust aroma Use fresh garlic cloves for the best depth skip the jarred kind if you can
- Worcestershire sauce: Adds savory umami Always check your bottle for a deep reddish brown color and no sediment
- Italian seasoning: Brings an herby note Dried blends are best check for mix with visible green specks
- Salt: Helps round out all the flavors Use fine sea salt so it dissolves well
- Ground black pepper: Adds a mild kick Freshly ground is always best for aroma
- Canned low sodium beef broth: Gives moisture and depth Pick a clear amber colored broth with minimal ingredients
- Canned diced tomatoes: Offer acidity and sweetness Use brands with only tomatoes and juice no extra flavors
- Uncooked long grain white rice: Soaks up all the goodness and cooks right in the pan Look for grains that are dry and not cracked
- Shredded mozzarella cheese: Melts perfectly for a smooth pull Use blocks and shred yourself for best melt
- Shredded cheddar cheese: Adds sharpness and golden color Again shred your own for richness and fewer additives
Instructions
- Brown the Beef:
- Heat a large skillet over medium heat Add the ground beef and break it into small pieces with a spatula Cook until mostly browned which draws out maximum flavor and helps the beef stay juicy
- Soften Vegetables:
- Add chopped onions and bell peppers to the skillet Keep the heat at medium and stir often for 5 to 10 minutes until they begin to soften and their color brightens This step deepens their flavor and makes the casserole sweeter
- Bloom the Garlic:
- Add minced garlic to the pan and cook for 1 to 2 minutes You will be able to smell when it hits its peak Keep moving the garlic around so it does not burn
- Combine Seasonings and Liquids:
- Pour in Worcestershire sauce Italian seasoning salt black pepper beef broth canned diced tomatoes and the uncooked rice Stir everything well to fully combine and make sure the rice is covered in liquids This helps it cook evenly later
- Simmer the Casserole:
- Raise the heat to bring the mixture to a soft boil Cover with a lid and lower the heat to a gentle simmer Cook for about 20 minutes stirring it halfway through to keep the rice from sticking Cook until the rice is soft and nearly all the liquid is absorbed
- Melt in the Cheese:
- Take off the lid and stir in half of the mozzarella and cheddar cheeses Keep stirring so the cheese melts into the casserole and makes it creamy and thick
- Finish with Cheese:
- Sprinkle the remaining cheese evenly over the top Recover the skillet until the cheese is melted and gooey If your skillet can go in the oven you can also place it under the broiler for a minute to get golden bubbly cheese
- Serve and Enjoy:
- Take the skillet off the heat Let it cool just briefly so it holds its shape when serving Plate up generous portions and watch everyone dig in

Bell peppers are my favorite part of this casserole I can never decide if I like the red or yellow peppers better When I was little I always reached for the pepper pieces first My mom used to sneak extra in just for me
