• 1 cup uncooked long-grain rice: The comforting, fluffy grain that soaks up all the amazing flavors.
• 2 cups beef broth (or chicken broth): Helps cook the rice while adding extra savory notes.
• 1 tsp Italian seasoning: A fragrant herb blend that brings classic Italian flair to the casserole.

How to Make Stuffed Pepper Casserole

Step 1: Preheat Your Oven

Start by getting your oven nice and warm at 375°F (190°C). This sets the stage for perfectly baked rice and gooey cheese, ensuring your casserole finishes with that satisfying bubbly top.

Step 2: Cook the Beef and Vegetables

Heat olive oil in a large oven-safe skillet or casserole dish over medium heat. Toss in the ground beef, diced onion, chopped bell peppers, and minced garlic. Cook everything together until the beef is browned and the vegetables soften, about 7 to 8 minutes. Drain any excess fat to keep the casserole from becoming greasy while letting those flavors shine.

Step 3: Add Rice and Sauce Mix

Now stir in the diced tomatoes, tomato sauce, uncooked rice, broth, and Italian seasoning along with salt and pepper. This combination forms the hearty base, where the rice soaks up all the savory juices as it cooks, becoming tender and flavorful.

Step 4: Bake Until Rice is Done

Cover your skillet or transfer the mixture if needed to a casserole dish, then pop it into the oven. Baking for 35 to 40 minutes allows the rice to properly absorb the broth and the flavors to meld into that classic Stuffed Pepper Casserole taste you love.

Step 5: Add That Melty Cheese Topping

After baking, take the casserole out and give it a good stir to blend everything beautifully. Then sprinkle the remaining shredded cheese evenly over the top. Return it uncovered to the oven for another 5 minutes until the cheese melts into a golden, bubbly crown of comfort.

Step 6: Serve and Enjoy!

Give your casserole a few minutes to cool slightly, then dish it out while still warm. The aroma alone will have everyone gathered around, eagerly digging into this delicious, easy-to-make Stuffed Pepper Casserole.

How to Serve Stuffed Pepper Casserole

Garnishes

A sprinkle of freshly chopped parsley or basil brightens the dish both visually and flavor-wise. A dollop of sour cream or a drizzle of hot sauce can add extra creaminess or a little spicy zing depending on what you prefer. These small touches elevate the casserole and make each bite feel like a special treat.

Side Dishes

Stuffed Pepper Casserole is wonderfully filling on its own but pairs beautifully with crisp green salads, steamed vegetables, or garlic bread. The crunch and freshness of these sides balance the savory richness, creating a well-rounded meal that’s both comforting and vibrant.

Creative Ways to Present

If you want to impress guests or simply shake things up, serve the casserole in individual ramekins for personal portions. You can also top servings with sliced avocado or a sprinkle of toasted pine nuts for unexpected texture and flavor contrasts. These little ideas keep your Stuffed Pepper Casserole fresh and exciting every time.

Make Ahead and Storage

Storing Leftovers

Keep your leftover Stuffed Pepper Casserole in an airtight container and refrigerate for up to 4 days. The flavors continue to meld, and reheating gently on the stove or microwave preserves the dish’s texture and taste.

Freezing

This casserole freezes wonderfully! Let it cool completely, then portion it into freezer-safe containers. It will maintain its delicious flavor and texture for up to 3 months. Just thaw overnight in the fridge before reheating for a quick, satisfying meal.

Reheating

Reheat leftovers in the oven at 350°F (175°C) until warmed through to keep the rice tender and the cheese melty. If using a microwave, cover loosely to retain moisture and stir halfway for even heating. Always check temperature before serving to ensure it’s hot and ready to enjoy.
