Ingredients That Make This Recipe Incredible
Ground Beef
Use lean ground beef for the best flavor without excessive grease. An 85/15 or 90/10 blend works beautifully.
White Rice
Long grain white rice cooks directly in the skillet and absorbs all the savory flavor from the broth and tomatoes.
Bell Peppers
Red, yellow, and green peppers add sweetness, texture, and that signature stuffed pepper flavor.
Tomato Sauce + Diced Tomatoes
These create the rich, cozy casserole base.
Cheese
Mozzarella and cheddar create the ultimate melty cheesy topping.
Italian Seasoning
Adds warmth and depth without overpowering the dish.
The Secret to the Best Stuffed Pepper Casserole
The key is allowing the rice to simmer directly in the sauce instead of cooking it separately.
When rice cooks in the seasoned broth and tomato mixture, it absorbs every layer of flavor from the beef, garlic, peppers, onions, and spices.
This creates a casserole that tastes richer and more cohesive than recipes where the rice is cooked separately.
How to Make Stuffed Pepper Casserole

Step 1: Brown the Ground Beef
Start by browning the ground beef in a large oven-safe skillet until deeply caramelized and flavorful.
Step 2: Sauté the Vegetables
Add diced onions and bell peppers directly into the skillet and cook until softened.
Step 3: Add Garlic and Seasonings
Garlic, Italian seasoning, smoked paprika, salt, and pepper build the savory flavor base.
Step 4: Stir in Rice and Tomato Mixture
Add uncooked white rice, tomato sauce, diced tomatoes, and broth.
Step 5: Simmer Until Tender
Cover and simmer until the rice becomes fluffy and tender.
Step 6: Add Cheese and Bake
Top with shredded cheese and transfer the skillet to the oven until bubbly and golden.
Why This Is the Ultimate One-Pot Dinner
This casserole is designed for maximum flavor with minimal dishes.
Using a stovetop-to-oven skillet allows you to:
- brown the meat
- cook the vegetables
- simmer the rice
- melt the cheese
- serve directly from the pan
No extra pots. No casserole dish. No mess.
Use a Caraway Stovetop-to-Oven Skillet
This recipe works beautifully in my favorite Caraway stovetop-to-oven skillet because it distributes heat evenly and transitions seamlessly from the stovetop straight into the oven.
The naturally slick ceramic surface makes browning ground beef and sautéing peppers incredibly easy while also helping prevent rice from sticking during simmering.
The deeper sides are perfect for one-pot meals like this stuffed pepper casserole because everything fits comfortably without overflowing.
Cleanup is also unbelievably easy — especially after cheesy baked casseroles.
If you’ve been looking for cookware that can truly handle weeknight meals from start to finish, Caraway is one of my absolute favorite kitchen upgrades.

Why ButcherBox Ground Beef Works So Well Here

If you make ground beef recipes often, it’s one of the easiest kitchen staples to keep on hand.
Tips for the Best Stuffed Pepper Casserole
Use Freshly Shredded Cheese
Freshly shredded cheese melts smoother and creamier than pre-shredded bags.
Dice Peppers Evenly
Uniform pieces cook more consistently throughout the casserole.
Keep the Lid On While Simmering
This helps the rice cook evenly and prevents excess moisture loss.
Let the Casserole Rest
Allowing the casserole to sit for 5 minutes before serving helps everything set up perfectly.
Easy Variations
Make It Spicy
Add crushed red pepper flakes or diced jalapeños.
Use Ground Turkey
Ground turkey works wonderfully for a lighter version.
Add Extra Vegetables
Mushrooms, zucchini, spinach, or corn all work beautifully.
Try Brown Rice
Brown rice can work, but it requires additional liquid and cooking time.
