Essential Ingredients for Your Stuffed Pepper Casserole
This Stuffed Pepper Casserole truly shines because of its simple yet robust ingredient list, designed to deliver maximum flavor with minimal fuss. Here’s a closer look at what makes this dish so deliciously easy:
- Ground beef: The foundation of this hearty casserole, ground beef provides rich, savory flavor and a satisfying texture. For a healthier option, you can choose leaner ground beef (90/10 or 93/7) or even opt for ground turkey.
- Bell peppers: We use a vibrant mix of red and green bell peppers. Red peppers bring a touch of sweetness and beautiful color, while green peppers offer a classic, slightly bitter counterpoint that is traditional in stuffed peppers. Dicing them ensures they cook evenly and blend seamlessly into the casserole.
- White rice: Uncooked white rice is a star here, absorbing all the delicious savory liquids and cooking directly in the dish. It creates a wonderfully tender base that soaks up every bit of flavor, contributing to the casserole’s comforting consistency.
- Worcestershire sauce: This secret weapon adds a crucial layer of rich, umami depth to the ground beef mixture. Its complex, savory notes elevate the overall flavor profile, making the casserole truly irresistible.
- Colby Jack cheese: The ultimate topping! Colby Jack cheese is known for its excellent melting properties, creating a gooey, creamy, and golden-brown crust over the casserole. Its mild, buttery flavor perfectly complements the other ingredients without overpowering them.

Step-by-Step: How to Make Stuffed Pepper Casserole
Creating this delicious Stuffed Pepper Casserole is surprisingly simple. Follow these easy steps to bring this comforting dish to life in your kitchen.
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly from the moment it enters the oven.
Step 2: Brown the Beef and Veggies
In a large skillet, place over medium heat. Add the ground beef along with the diced yellow onion and bell peppers. Cook, breaking up the beef with a spoon as it browns, until it’s no longer pink and the vegetables have softened. This typically takes about 8-10 minutes. Once cooked, drain any excess grease to prevent the casserole from becoming oily. A well-browned beef adds significant flavor to your casserole.
Step 3: Combine and Assemble
Lightly spray a 9×13 inch baking dish with nonstick cooking spray to prevent sticking. Transfer the cooked beef and vegetable mixture into the prepared baking dish. Add the uncooked white rice, Worcestershire sauce, diced tomatoes (including their juice), beef broth, water, salt, pepper, paprika, Italian seasoning, and ½ cup of the shredded Colby Jack cheese. Stir all ingredients thoroughly until everything is well combined and evenly distributed. This ensures every bite is flavorful.
Step 4: Initial Bake (Covered)
Cover the baking dish tightly with aluminum foil. Place it in your preheated oven and bake for 40 minutes. Covering the dish is crucial for allowing the rice to steam and cook perfectly, absorbing all the wonderful liquids and flavors.
Step 5: Add More Cheese and Finish Baking
After 40 minutes, carefully remove the foil from the baking dish. Give the casserole a gentle stir to redistribute the ingredients and check on the rice. Then, evenly sprinkle the remaining 1 cup of shredded Colby Jack cheese over the top of the casserole. This will create that irresistible gooey, cheesy layer.
Step 6: Final Bake (Uncovered)
Return the uncovered casserole to the oven and bake for an additional 15 minutes. Continue baking until the rice is perfectly tender, and the cheese on top is beautifully melted, bubbly, and slightly golden brown. This step brings all the elements together into a cohesive, comforting dish.
Step 7: Check Rice Tenderness (Optional Adjustment)
If, after the final bake, the rice is still a bit firm or crunchy, don’t worry! Simply add 1 more cup of water or beef broth to the casserole, stir it in, and cover the dish again with foil. Return it to the oven and continue baking in 10-15 minute increments until the rice is fully cooked and tender to your liking.

Stuffed Pepper Casserole Variations for Every Taste
One of the best things about this Stuffed Pepper Casserole is how easily it adapts to different dietary preferences and ingredient availability. Feel free to get creative with these delicious variations:
- Swap Your Protein: For a lighter take on this comforting dish, you can easily substitute ground turkey or ground chicken for the ground beef. When using poultry, you might want to add a touch more olive oil when browning and consider adjusting seasonings slightly, as ground poultry can be milder in flavor.
- Alternate Grains: While white rice cooks perfectly in this casserole, you can use brown rice for an added fiber boost and a nuttier flavor. Keep in mind that brown rice typically requires a longer cooking time and more liquid. Expect to add about 15-20 extra minutes to the initial covered baking time and potentially a bit more broth or water.
- Boost Your Veggies: Enhance the nutritional value and texture by incorporating more vegetables. Diced zucchini, mushrooms, or even spinach can be added to the beef mixture during the browning stage. Make sure to sauté them briefly to release some moisture before adding other ingredients.
- Spice It Up with Cheese: If you enjoy a little heat, swap out the Colby Jack cheese for pepper jack cheese. Its subtle kick will add an exciting dimension to the casserole, while still providing that fantastic melty texture. For an extra rich flavor, a blend of Gruyère and cheddar also works wonderfully.

My Pro TipS
Expert Tips and Tricks for a Perfect Casserole
Achieving the perfect Stuffed Pepper Casserole is easy with these simple tips:
- Ensure Even Rice Cooking: The key to tender, perfectly cooked rice in a casserole is a tight seal. Always cover the dish tightly with aluminum foil during the initial baking phase. This traps steam and moisture, ensuring the rice cooks thoroughly and evenly without drying out.
- Adjust for Brown Rice: If you opt for brown rice, remember it’s denser and requires more time. Plan to add approximately 15-20 extra minutes to the initial covered bake time to ensure it becomes tender. You might also need a splash more liquid.
- Shred Your Own Cheese: For the absolute best melt and creaminess, I highly recommend shredding your own block of Colby Jack cheese (or whatever cheese you choose). Pre-shredded cheeses often contain anti-caking agents that can hinder smooth melting, resulting in a less desirable texture.
- Let It Rest: Patience is a virtue when it comes to casseroles! Allow the Stuffed Pepper Casserole to rest for at least 5-10 minutes after removing it from the oven. This crucial resting period allows the flavors to meld, the rice to absorb any remaining liquid, and the casserole to set up, making it easier to serve clean portions.
Frequently Asked Questions About Stuffed Pepper Casserole
Here are some common questions to help you master this delightful Stuffed Pepper Casserole:
Absolutely! This casserole is fantastic for meal prep. You can prepare the entire casserole up to the baking step (before covering with foil and baking). Cover it tightly with plastic wrap or foil and refrigerate for up to 24 hours. When you’re ready to bake, simply follow the baking instructions, adding a few extra minutes to the covered bake time if baking from cold to ensure it heats through evenly.
Yes, you can use instant rice for an even quicker cooking time. However, you’ll need to significantly adjust the liquid. Reduce the beef broth and water by about half (start with 1 cup total liquid) and bake the casserole uncovered from the start, as instant rice doesn’t require steaming like regular rice. Keep a close eye on it, as cooking times will be much shorter.
This casserole freezes beautifully! Allow the cooked casserole to cool completely to room temperature. Then, wrap it tightly in a double layer of plastic wrap and a layer of aluminum foil. Freeze for up to 2 months. To reheat, thaw overnight in the refrigerator, then bake covered in the oven at 350°F (175°C) until heated through, typically 30-45 minutes. You can also freeze individual portions for convenient grab-and-go meals.
Colby Jack is fantastic for its smooth melt and mild, creamy flavor. Mozzarella also melts beautifully and provides a lovely stretch. If you prefer a sharper taste, a good quality medium or sharp cheddar cheese works very well and adds a tangy kick. Feel free to experiment with a blend of your favorite melting cheeses!

Perfect Serving Suggestions for Your Casserole
This Stuffed Pepper Casserole is a complete meal on its own, but pairing it with a simple side can elevate your dinner experience. Here are a few ideas:
- Fresh Green Salad: A crisp green salad with a light vinaigrette dressing offers a refreshing contrast to the rich, hearty casserole.
- Steamed Vegetables: Simple steamed vegetables like green beans, broccoli, or asparagus add a healthy and vibrant element to the plate without much fuss.
- Garlic Bread or Crusty Rolls: A slice of warm garlic bread or a crusty dinner roll is perfect for soaking up any delicious juices from the casserole, adding a satisfying texture contrast.
- Optional Toppings: Enhance individual servings with a dollop of sour cream or a sprinkle of fresh chopped parsley or chives for extra flavor and a pop of color.
Make-Ahead, Storage & Reheating Tips for Convenience
This casserole is a dream for meal planning and busy schedules, thanks to its excellent make-ahead and storage capabilities. Here’s how to manage it:
- Make Ahead: Assemble the entire casserole (up to the baking step) in your baking dish. Cover tightly with foil or plastic wrap and refrigerate for up to 24 hours. When ready to bake, add an extra 10-15 minutes to the covered baking time to ensure it heats through.
- Fridge Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. This makes it perfect for delicious lunches throughout the week.
- Freezer Storage: For longer storage, allow the casserole to cool completely. Wrap it tightly in a double layer of plastic wrap, then an additional layer of aluminum foil. It will keep well in the freezer for up to 2 months. For ultimate convenience, consider portioning the casserole into single servings before freezing. This way, you can grab and reheat exactly what you need.
- Reheating: To reheat, simply warm individual portions in the microwave until hot throughout. For a larger portion or if reheating from frozen (after thawing overnight), cover the casserole and reheat in the oven at 350°F (175°C) until it’s piping hot and bubbly. Covering helps retain moisture and prevents the rice from drying out.
