The Story Behind This Stuffed Pepper Casserole Recipe
Hi, I’m Abby Pinkmann, founder of EAT WELL.
Growing up in a large family just outside Austin, Texas, dinner was always the busiest part of the day. My mom had a way of turning simple ingredients into comforting meals without spending hours in the kitchen. One of her favorite cold-weather dinners was stuffed peppers. The flavors were always wonderful, but stuffing each pepper took time.
Years later, when I started cooking for my own family, I wanted those same savory flavors with a faster approach. That’s how this stuffed pepper casserole recipe became a regular part of my meal rotation.
Instead of filling individual peppers, everything bakes together in one dish. The result is tender bell peppers, juicy ground beef, fluffy rice, rich tomato sauce, and a blanket of melted cheese with lightly golden edges. It delivers all the comfort of traditional stuffed peppers while keeping prep work simple.
If you love classic comfort food casseroles, this recipe deserves a spot in your dinner lineup.

What Is a Stuffed Pepper Casserole Recipe?
A stuffed pepper casserole recipe combines ground beef, bell peppers, rice, tomatoes, seasonings, and cheese into a single baked dish. It offers the same flavor profile as traditional stuffed peppers but requires less preparation and fewer cooking steps.
Traditional stuffed peppers require hollowing peppers, preparing the filling, stuffing each pepper, and baking them individually.
With a casserole, all those ingredients mix together in one pan. The flavors blend beautifully as the casserole bakes, creating a hearty meal that satisfies everyone at the table.
This dish has become popular because it balances convenience with classic comfort food flavor.

It’s the kind of recipe that works equally well for a casual Tuesday night dinner or a weekend family gathering.

How to Make Stuffed Pepper Casserole Recipe
The best stuffed pepper casserole recipe comes together by cooking the beef and vegetables first, mixing them with rice and tomato sauce, then baking everything until bubbly. A layer of melted cheese finishes the dish with rich flavor and a beautiful golden top.
Step 1: Prepare the Oven
Preheat your oven to 375°F.
Lightly grease a 9×13-inch baking dish.
Step 2: Brown the Ground Beef
Heat a large skillet over medium heat.
Add the ground beef and cook until browned.
Break the meat into small crumbles as it cooks.
Drain excess fat if needed.
Step 3: Cook the Vegetables
Add:
- Diced bell peppers
- Onion
- Garlic
Cook for about 5 minutes.
The peppers should soften slightly while still maintaining some texture.
The aroma at this stage is one of my favorite parts of the recipe.
Step 4: Add Tomatoes and Seasonings
Stir in:
- Tomato sauce
- Diced tomatoes
- Salt
- Pepper
- Paprika
- Italian seasoning
- Onion powder
- Garlic powder
Mix thoroughly.
Allow everything to simmer for 3 to 5 minutes.
Step 5: Add Rice
Fold the cooked rice into the mixture.
Stir until every grain becomes coated with the tomato mixture.
Step 6: Transfer to Baking Dish
Pour the mixture into the prepared casserole dish.
Spread it evenly.
Cover with foil.
Bake for 25 minutes.
Step 7: Add Cheese
Remove the foil.
Sprinkle shredded cheddar cheese evenly across the top.
Return the casserole to the oven.
Bake another 10 to 15 minutes.
The cheese should become melted and lightly golden around the edges.
Allow the casserole to rest for 5 minutes before serving.

Why This Is the Best Stuffed Pepper Casserole Recipe
Many casserole recipes taste heavy or one-dimensional.
This one stays balanced because each ingredient serves a purpose.
Bell Peppers Add Fresh Flavor
Bell peppers contribute sweetness and texture.
Using multiple colors creates a more vibrant casserole.
Red peppers add sweetness.
Green peppers add a slightly earthy note.
Yellow and orange peppers bring mild sweetness and bright color.
Rice Creates the Perfect Texture
Rice absorbs the tomato sauce while keeping the casserole filling and satisfying.
Long-grain white rice works especially well.
Brown rice also works if you prefer a slightly nuttier flavor.
Cheese Creates a Golden Finish
A generous layer of cheddar cheese provides creamy richness.
As it melts, the edges become slightly crisp and golden brown.
That contrast between creamy and lightly crisp textures makes every bite more satisfying.
Easy Stuffed Pepper Casserole Recipe Variations
One reason I love this recipe is its flexibility.
You can adapt it based on what you have available.
Easy Stuffed Pepper Casserole Recipe With Ground Turkey
Ground turkey works beautifully.
It creates a lighter casserole while maintaining excellent flavor.
Simply replace the ground beef with an equal amount of turkey.
One Pot Stuffed Pepper Casserole
You can make a true one pot stuffed pepper casserole by using a large oven-safe skillet.
Cook everything in the skillet and transfer it directly into the oven.
Cleanup becomes even easier.
One Pan Stuffed Pepper Casserole
A one pan stuffed pepper casserole is perfect when you want fewer dishes.
Mix everything directly in your baking dish after browning the meat.

Common Mistakes to Avoid
Using Too Much Liquid
Extra liquid can make the casserole soupy.
Measure carefully.
Cooked rice already contributes moisture retention.
Overcooking the Peppers
Bell peppers should remain slightly tender.
Cooking them too long before baking can cause them to become overly soft.
Skipping the Resting Time
Allow the casserole to rest after baking.
This helps the ingredients settle and makes serving easier.
What to Serve With Stuffed Pepper Casserole
