Stuffed pepper casserole with beef takes the same ground beef, rice, and bell pepper filling used in classic stuffed peppers and bakes it together in one pan instead of individually stuffed shells. It comes together faster, holds up well as leftovers, and tastes just as rich as the original version. This one uses browned beef, diced peppers, rice, and a tomato-beef sauce finished with melted cheddar.
The first time I tried making traditional stuffed peppers, I spent close to forty minutes cutting tops, scooping seeds, and propping peppers upright so they wouldn’t tip over in the oven. Halfway through, I gave up on the shape entirely and dumped everything into one skillet instead. That kitchen shortcut turned into the recipe I make now, and it’s the one my family actually asks for.
This casserole works well for busy weekday dinners, meal prep, or feeding a crowd without babysitting individual peppers. If you like beef and rice stuffed peppers but not the fuss of stuffing them, this recipe gives you the same flavor with far less effort.

Before You Get Started
- Use a large oven-safe skillet or Dutch oven with a tight-fitting lid. If you don’t have one, cook everything on the stovetop, then transfer it to a covered casserole dish before baking.
- Dice the peppers into pieces around 1 inch across so they hold their shape but still cook through easily.
- I tested this once with instant rice, and it turned mushy long before the peppers were tender. Stick with regular long-grain white rice for the best texture.
- Brown the beef in batches if your skillet feels crowded. Too much meat at once steams it instead of browning it, and browning is where a lot of the flavor comes from.
- Swap ground beef for ground turkey or Italian sausage if you want a different flavor profile — see the substitution table below for how each option changes the dish.
- Let the casserole rest for 10 minutes after baking. This gives the rice time to fully absorb the liquid so the filling holds together when you serve it.
Ingredients
- 4 large bell peppers, diced into 1-inch pieces (mixed colors work well)
- 1 pound ground beef (85/15)
- 1 tablespoon olive oil
- 3 cloves garlic, minced
- 1 teaspoon smoked paprika
- 1/2 teaspoon garlic powder
- 1/4 teaspoon cayenne pepper
- 1/2 teaspoon black pepper
- 1 teaspoon kosher salt, plus more to taste
- 1 tablespoon Worcestershire sauce
- 1 cup uncooked long-grain white rice
- 2 cups tomato sauce
- 1 1/2 cups beef broth
- 2 cups shredded cheddar cheese, divided
- 2 tablespoons chopped fresh parsley, for garnish
Instructions
Step 1: Prep the Peppers
Cut the top and bottom off each bell pepper. Slice down one side, lay each pepper flat, and cut away the ribs and seeds. Dice into pieces roughly 1 inch across and set aside.
In my kitchen, I cut the peppers into long strips first, then slice across the strips into pieces. It’s faster than dicing straight from a whole pepper and easier to keep the pieces an even size.
Step 2: Brown the Beef
Heat the olive oil in a large oven-safe skillet over high heat. Add the ground beef and a pinch of salt. Break it apart with a spatula and cook for 5 to 6 minutes, stirring occasionally, until deeply browned.
I learned this step matters more than it looks after rushing it in my first batch. The beef stayed pale, and the finished casserole tasted flat. Give it the full time and don’t stir too often.
Step 3: Add Garlic and Spices
Reduce the heat to medium-high. Stir in the garlic and cook for about 1 minute, until fragrant. Add the smoked paprika, garlic powder, cayenne, and black pepper, then stir for another minute to toast the spices in the fat.
Step 4: Cook the Peppers and Rice
Add the diced peppers to the skillet and cook for 2 to 3 minutes, just until they start to soften. Stir in the uncooked rice and cook for 1 minute so it picks up some of the fat in the pan.
In my testing, this one extra minute made a real difference. The rice held its shape much better after baking compared to batches where I skipped it.
Step 5: Add Liquid and Simmer
Pour in the Worcestershire sauce, tomato sauce, and beef broth. Stir everything together and raise the heat to high. Bring the mixture to a steady simmer, then remove it from the heat.
Step 6: Bake
Stir 1 cup of the shredded cheese into the skillet. Cover tightly and transfer the pan to a 375°F oven. Bake for 45 minutes, or until the rice is tender when you test it with a spoon.
Step 7: Finish and Serve
Remove the lid and sprinkle the remaining 1 cup of cheese over the top. Broil for 2 to 3 minutes, until the cheese melts and turns lightly golden. Let the casserole rest for 10 minutes, then top with chopped parsley before serving.
How To Make (Quick Reference)
- Dice bell peppers into 1-inch pieces.
- Brown ground beef in olive oil, 5 to 6 minutes.
- Stir in garlic and spices; cook for 1 minute.
- Add peppers, cook 2 to 3 minutes; stir in rice, cook for 1 minute.
- Add Worcestershire sauce, tomato sauce, and beef broth; bring to a simmer.
- Stir in 1 cup cheese, cover, and bake at 375°F for 45 minutes.
- Top with remaining cheese, broil 2 to 3 minutes, rest 10 minutes, and serve.
Tips for Best Results
- Stick with long-grain white rice instead of instant rice. I tried it instant once, and it turned to mush well before the peppers were tender.
- Use an oven-safe skillet if you have one. Moving hot liquid into a separate casserole dish is messier than it needs to be.
- Taste the sauce before baking and adjust the salt. Tomato sauce brands vary quite a bit in sodium.
- If the rice looks slightly underdone at the 45-minute mark, cover it again and bake for another 5 to 10 minutes rather than pulling it early. I rushed this once and ended up with crunchy rice in the center of the pan.
- Broil in short bursts and watch closely. Cheese can go from golden to burnt in under a minute.
Ingredient Substitutions
| Original Ingredient | Substitute | Effect on Taste/Texture |
| Ground beef | Ground turkey | Lighter flavor, slightly drier; add an extra tablespoon of oil |
| Long-grain white rice | Brown rice | Chewier texture; needs 15–20 extra minutes covered in the oven |
| Cheddar cheese | Monterey Jack | Milder flavor, melts smoother with less oil separation |
| Beef broth | Chicken broth | Slightly lighter sauce; flavor difference is minor |
| Bell peppers | Poblano peppers | Adds mild heat and a deeper, smokier flavor |
Storage & Reheating
Store leftover stuffed pepper casserole with beef in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1 to 2 minutes, stirring halfway through.
For a larger batch, reheat covered in a 350°F oven for about 15 minutes, until warmed through. This casserole also freezes well for up to 3 months — thaw it overnight in the refrigerator before reheating.
FAQs
Can I make stuffed pepper casserole with beef ahead of time?
Yes. Assemble the casserole up to the point of baking, cover it, and refrigerate for up to 24 hours. Add about 10 extra minutes to the covered baking time since the ingredients start out cold, then finish with cheese and broil as directed.
Why is my rice still hard after baking?
This usually means the rice needs more time, or the lid wasn’t sealed tightly enough and let liquid evaporate too fast. Cover the pan again and bake in 10-minute increments, checking each time, until the rice turns tender.
Can I use cooked rice instead of uncooked rice?
Yes, but reduce the beef broth by about 1 cup since cooked rice won’t absorb as much liquid. Add the cooked rice during the last 15 minutes of baking so it doesn’t turn mushy from the extra oven time.
What can I serve with a stuffed pepper casserole?
A simple green salad balances the richness of this dish nicely. Garlic bread or steamed vegetables like green beans also work well alongside it, since the casserole itself is fairly hearty on its own.
Can I freeze stuffed pepper casserole with beef?
Yes, it freezes well for up to 3 months in an airtight, freezer-safe container. Thaw it in the refrigerator overnight, then reheat covered in a 350°F oven for about 20 minutes, or until heated through.
