How to Make Easy Stuffed Pepper Casserole
Step 1: Sauté Onion and Garlic
Start by heating the olive oil in a large skillet or Dutch oven over medium heat. Toss in your diced onion and let it cook for two to three minutes, just until it’s softened and smells sweet. Next up, stir in the minced garlic and let that go for about thirty seconds—it’s a tiny step, but it truly unlocks those deep, savory flavors that make this Easy Stuffed Pepper Casserole taste incredible.
Step 2: Cook the Beef and Bell Peppers
Now, add the diced red and green bell peppers, followed by your ground beef. Stir everything together and break up the meat as it cooks. Let this simmer away until the beef is browned and the peppers are just starting to soften, about five or six minutes. Don’t forget to drain any excess fat—this keeps your casserole from feeling greasy while still delivering big, bold flavors.
Step 3: Add the Rice and Saucy Ingredients
Pour in the uncooked rice, beef broth, diced tomatoes with their juice, tomato sauce, Italian seasoning, salt, and black pepper. Stir it all together so that the rice is evenly distributed and ready to soak up every savory drop. Everything should look vibrant and promise a dish packed with comfort.
Step 4: Simmer Until Tender
Bring the whole mixture to a gentle boil, then reduce the heat to low and cover your pan. Let it simmer for twenty to twenty-five minutes. During this time, the rice will absorb the flavorful liquid, the peppers will become deliciously tender, and those tomatoes will meld perfectly with the beef. Give it a peek toward the end, and if the rice is fluffy and most of the liquid has vanished, you’re on the right track!
Step 5: Finish with Cheddar Magic
Remove your pan from the heat, then sprinkle that glorious, shredded cheddar cheese all over the top. Pop the lid back on and let everything sit for about five minutes. This brief wait time lets the cheese melt into a gooey blanket, sealing in the moisture and making the Easy Stuffed Pepper Casserole simply irresistible.
Step 6: Garnish and Serve
Just before serving, scatter some chopped fresh parsley over the top for a fresh, herby kick. Now you’re ready to dish up hearty spoonfuls that will win over any crowd—hungry kids, busy adults, or anyone in need of serious comfort food!
How to Serve Easy Stuffed Pepper Casserole

Garnishes
Garnishing is the fun part that takes your Easy Stuffed Pepper Casserole from homey to truly inviting. A sprinkle of chopped fresh parsley or even a handful of sliced green onions adds a lovely pop of color and a fresh bite. You could also grate a bit of Parmesan on top for an extra punch of savory goodness if you like!
Side Dishes
This casserole is definitely a meal on its own, but it plays nicely with simple sides. Serve with a crisp mixed green salad to add freshness, or warm up some crusty bread to soak up every bit of the saucy goodness. Roasted broccoli or green beans always makes a happy partnership too.
Creative Ways to Present
If you’re serving a crowd or planning a potluck, spoon the Easy Stuffed Pepper Casserole into individual ramekins or small bowls for a charming, personal presentation. Top each with a colorful bell pepper ring or a dollop of sour cream—no one will guess how simple it was to make!
Make Ahead and Storage
Storing Leftovers
Leftover Easy Stuffed Pepper Casserole stores like a dream. Just scoop the cooled casserole into an airtight container and refrigerate it for up to four days. The flavors meld and deepen overnight, making your next meal even tastier!
Freezing
This casserole is wonderfully freezer-friendly. Freeze individual portions or the whole batch in airtight containers for up to three months. Just be sure everything is completely cool before freezing to prevent freezer burn and keep that texture spot-on.
Reheating
For best results, reheat portions in the microwave or on the stovetop, adding a splash of broth or water to loosen things up if needed. Sprinkle on a little extra cheese before heating if you want an especially gooey, fresh-from-the-oven experience!
FAQs
Can I use brown rice instead of white?
Absolutely! Just know that brown rice takes a bit longer to cook and you may need to add a little extra beef broth to keep things nice and saucy. The nutty flavor is a delicious twist!
Is this recipe gluten-free?
Yes—Easy Stuffed Pepper Casserole is naturally gluten-free as written, provided your broth and other packaged ingredients are certified gluten-free. It’s a fantastic option for family members avoiding gluten.
Can I make this vegetarian?
You bet! Simply use your favorite plant-based ground “meat” or even cooked lentils instead of ground beef, and swap in vegetable broth. You’ll still get all the hearty texture and flavor.
How do I make it spicier?
If you like a little heat, stir in a generous pinch of red pepper flakes or a diced jalapeño when cooking the vegetables. A dash of hot sauce right before serving also works wonders.
