Preparing Stuffed Pepper Casserole
Making a stuffed pepper casserole is both simple and incredibly satisfying. Follow these steps to create a delicious meal that’s perfect for any weeknight dinner.
Gathering Your Ingredients and Tools
Before diving into preparation, make sure you’ve got everything you need. Here’s a list of key ingredients:
- Olive oil
- Yellow onion
- Red and green bell peppers
- Ground beef
- Tomato paste
- Kosher salt, cumin, paprika, and black pepper
- Garlic
- Vine-ripened tomatoes
- Zucchini
- Chicken broth
- Long-grain white rice
- Fresh parsley or cilantro
- Worcestershire sauce
- Pepper jack cheese
You’ll also want to have your trusty skillet and a baking dish (about 3-quarts) ready to go. This is a fun part of cooking; having everything prepped and organized makes the process smoother and more enjoyable.
Preparing the Vegetables and Meat
Start by heating up some olive oil in your skillet over medium heat. Once it’s warm, add your onions, red bell pepper, and green bell pepper. Cook these for about 3 to 5 minutes until they become soft and fragrant. This step really enhances the flavors of your stuffed pepper casserole.
Next, toss in the ground beef and break it up with a wooden spoon. Brown it for about 6 to 8 minutes until it’s no longer pink. At this point, mix in the tomato paste, spices, and garlic. Stir everything around until it’s aromatic — the smell will be mouthwatering!
Combining All Ingredients in a Skillet
After your meat and veggies are ready, it’s time to add the chopped tomatoes and zucchini. Let these simmer for another 3 to 5 minutes until everything is nice and tender. Then, stir in the chicken broth, rice, fresh herbs, Worcestershire sauce, and a cup of cheese.
This mixture is what will give your stuffed pepper casserole its heartiness and flavor. Once everything is combined, remove it from heat.
Transferring the Mixture to the Baking Dish
Grease your baking dish with a little olive oil to prevent sticking. Spoon the flavorful mixture from your skillet into the dish, spreading it out evenly. Cover it with aluminum foil to lock in the moisture — this is crucial for cooking the rice properly.
Baking to Perfection
Now, pop your casserole into the preheated oven at 350°F. Bake it for about 50 minutes to an hour. You’ll know it’s done when the rice is tender and has absorbed most of the liquid.
Broiling for a Cheesy Finish
Once the baking time is up, remove the foil and stir the casserole gently. Sprinkle the remaining cheese on top, and then turn your oven to broil. Let it broil for just 2 to 3 minutes until the cheese is all melty and bubbly. Trust me, this step takes the stuffed pepper casserole from good to absolutely irresistible.
Allow it to cool for a few minutes, then serve up this comforting dish with a sprinkle of fresh herbs on top. Enjoy!

Variations on Stuffed Pepper Casserole
Vegetarian Stuffed Pepper Casserole
For a delightful vegetarian twist, swap out the ground beef for black beans or chickpeas. Add in extra veggies like diced carrots or corn, and use vegetable broth instead of chicken. This variation is packed with protein and flavor, making it a hearty yet healthy option that everyone will enjoy.
Southwest Flavor Twist
Craving something with a kick? Transform your stuffed pepper casserole by introducing spices like cayenne pepper or chipotle powder for a smoky, southwest flavor.
