Step‑by‑Step Instructions for Savory Stuffed Pepper Casserole

Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Savory Stuffed Pepper Casserole will bake evenly and thoroughly. While the oven warms, you can prepare the rest of your ingredients, making the cooking process smoother and more efficient.

Step 2: Brown Beef
In a large skillet, heat a drizzle of olive oil over medium-high heat. Add the lean ground beef and cook, stirring occasionally, for about 6-8 minutes until it is browned and cooked through. As it cooks, use a spatula to break it into small pieces, ensuring even browning and a hearty base for your casserole.

Step 3: Sauté Vegetables
Next, add the diced yellow onion, red bell pepper, and green bell pepper to the skillet with the beef. Sauté these colorful veggies for about 5-7 minutes, or until they are tender and the onion becomes translucent. Stir in minced garlic and let it cook for another minute, releasing its aromatic flavor into the mixture.

Step 4: Season
Now, sprinkle in the Italian seasoning, Worcestershire sauce, salt, and ground black pepper. Stir everything together and let it simmer for about 1 minute. This step enhances the flavors of your Savory Stuffed Pepper Casserole, adding depth and richness as the spices meld with the meat and vegetables.

Step 5: Combine Rice & Liquid
Time to bring the casserole together! Stir in the canned diced tomatoes, uncooked long-grain white rice, and beef broth. Increase the heat until the mixture reaches a boil, then reduce to low, cover, and let it simmer for about 20 minutes. This allows the rice to absorb the flavors and moisture, becoming an integral part of the casserole.

Step 6: Assemble Casserole
Once the rice is tender and has absorbed most of the liquid, transfer the hearty mixture into a greased baking dish. Spread it out evenly and then sprinkle a generous layer of shredded cheese on top. This cheesy topping not only enhances the flavor but will create a beautiful golden crust as it bakes.

Step 7: Bake
Place the baking dish into your preheated oven and bake for 25 minutes. Keep an eye on it, and watch for the cheese to melt and bubble, turning a lovely golden color. Your Savory Stuffed Pepper Casserole will be full of delightful aromas filling your kitchen, creating anticipation for the meal.

Step 8: Rest & Garnish
After baking, remove the casserole from the oven and let it rest for about 5 minutes. This resting period helps the layers settle. Just before serving, sprinkle chopped fresh parsley over the top for a burst of color and freshness, adding a delightful finishing touch to this comforting dish.

Stuffed Pepper Casserole Recipe FAQs

What type of bell peppers are best for this casserole?
Absolutely! While red, green, and yellow bell peppers all work beautifully, I recommend using a mix for added color and flavor. Red peppers provide sweetness, while green ones add a mild crunch. If you want variety, consider orange or even poblano peppers for a touch of heat!

How should I store leftovers from my Stuffed Pepper Casserole?
Store any leftovers in an airtight container in the refrigerator for up to 4 days. Make sure to let the casserole cool completely before sealing, ensuring the best preservation of flavors and texture.

Can I freeze the Stuffed Pepper Casserole?
Very! To freeze, allow the casserole to cool completely, then transfer it to a freezer-safe container. Seal tightly and store for up to 3 months. When you’re ready to enjoy, thaw it overnight in the refrigerator before reheating in the oven at 350°F (175°C) for 20-25 minutes, or until heated through.

What if my rice is still crunchy after cooking?
If your rice is still a bit firm after simmering, it may need a little extra moisture. Simply add a splash more beef or vegetable broth, cover, and continue simmering for another 5-10 minutes. This will help steam the rice and make it tender. Always ensure the lid stays on during this process to keep the steam trapped inside.

Can I make this casserole vegetarian-friendly?
Absolutely! To create a vegetarian version of the Stuffed Pepper Casserole, swap out the ground beef for a can of black beans, kidney beans, or lentils. You’ll maintain that hearty feel while boosting nutritional value! Consider adding extra vegetables like zucchini or corn for even more flavor.
