🍳 Instructions: How to Make Stuffed Pepper Casserole

Browning the Meat & Peppers

Bringing this Stuffed Pepper Casserole to life is surprisingly simple—and it all starts with layering flavors right from the skillet. This quick stovetop prep is what gives your casserole that rich, hearty taste we all crave. 🍴

1️⃣ Preheat your oven to 375°F so it’s ready to go when your filling is complete.
2️⃣ In a large skillet, heat 1 tablespoon olive oil over medium heat.
3️⃣ Place your ground beef or turkey into the skillet to begin cooking. Using a spatula or wooden spoon, break it apart and cook until fully browned and no longer pink—about 5 to 7 minutes.
4️⃣ Mix in the chopped onions, sliced bell peppers, and finely minced garlic. Sauté for another 5–7 minutes, or until the veggies soften and become fragrant. You’ll start smelling that irresistible aroma at this point! 😋

Building Layers of Flavor

With your meat and veggies cooked, it’s time to bring the whole dish together with deep, savory flavor.

5️⃣ Add oregano, smoked paprika, salt, and black pepper to flavor the blend. Stir everything thoroughly so the spices coat each bite.
6️⃣ Pour in the diced tomatoes and tomato sauce. Mix well, then reduce heat slightly and let it simmer for about 5 minutes—this step allows the flavors to blend beautifully.
7️⃣ Now, fold in your cooked rice. Stir until evenly combined. Take a quick taste and adjust seasonings as needed (a pinch more salt or paprika can do wonders!).

Baking to Perfection

Now for the final, bubbly finish:

8️⃣ Pour the mixture into a prepared 9×13-inch baking dish, spreading it into an even layer.
9️⃣ Sprinkle generously with shredded cheese—choose your favorite blend for that gooey, golden topping. 🧀
🔟 Place the dish in your oven and bake uncovered for 20 minutes, or until hot, bubbly, and beautifully melted on top.

Once baked, garnish with fresh parsley for a pop of color and brightness. Serve warm and enjoy—you’ve just made a wholesome, comforting dinner the whole family will love. ❤️

🌀 Variations on Stuffed Pepper Casserole

Mix & Match Ingredients

One of the things I love most about this Stuffed Pepper Casserole is how flexible it is — once you’ve got the base recipe down, you can make it your own with just a few creative twists. Whether you’re cooking for picky eaters or experimenting with flavors, here are some fun ways to switch things up:

Vegetarian Version → Skip the meat and swap in cooked lentils, black beans, or a mix of both for a plant-based protein boost 🌱
Extra Cheesy → Double the cheese or layer extra cheese between the rice and meat mixture for an ultra-gooey, indulgent bake
One-Pot Wonder → Want fewer dishes? Cook the rice right in the sauce with a little extra broth—just simmer until tender
Low-Carb Option → Use cauliflower rice instead of traditional rice for a lighter, low-carb version
Turn Up the Heat → Add red pepper flakes, jalapeños, or even a dash of hot sauce to give it a spicy edge 🌶️

❓ Should peppers be cooked before stuffing?

For this casserole version, there’s no need to pre-cook the bell peppers! Since they’re diced and sautéed briefly with the onions and garlic, they’ll soften beautifully while baking. This keeps the process simple and gives the casserole that tender, slightly crisp texture we love.

❓ Is stuffed pepper casserole healthy?

It can absolutely be a balanced, wholesome meal! With lean protein, bell peppers, tomatoes, and rice, it offers a good mix of nutrients. Want to make it even lighter? Try using ground turkey, cauliflower rice, or adding extra veggies like spinach or zucchini.

❓ What seasoning is good for stuffed peppers?

Classic seasonings like oregano, smoked paprika, garlic, salt, and black pepper are delicious here. You can also add Italian seasoning for a more herb-forward flavor, or red pepper flakes for a little heat. Don’t be afraid to adjust to your family’s taste!

❓ What goes with stuffed peppers as a side?

You have plenty of options! I love serving this casserole with:
A crisp green salad
Garlic bread
Steamed veggies
Or even a light cucumber-tomato salad for something bright and fresh

And if you’re in the mood for something sweet after dinner, our delightful Blueberry Cloud Jello Salad is a fantastic choice — light, fruity, and perfect with any casserole meal!
