Ingredients for Stuffed Pepper Casserole

Gathering the right ingredients is the first step towards whipping up this cozy meal. Here’s what you’ll need:

Olive oil: A staple in my kitchen, this oil adds flavor and helps brown the meat.
Ground beef: Juicy and satisfying, it’s the heart of this dish. Feel free to use lean beef for a healthier option.
Ground mild Italian sausage: This brings a flavorful kick that perfectly complements the beef. You might use turkey sausage for a leaner alternative.

Yellow onion: Diced and sautéed, onions add a sweet depth to the casserole.
Bell peppers: I love using a medley of red, yellow, and green. Their colors make the dish pop and their sweetness balances the savory flavors.
Garlic: Fresh minced garlic adds aromatic goodness. You can always substitute with garlic powder if you’re in a pinch.

Italian seasoning blend: A mix of herbs that enhances the flavor, making every bite delightful.
Salt and black pepper: Essential seasonings to enhance all the other flavors in the dish.
Tomato paste: It adds richness and depth. I often keep some in my pantry for last-minute cooking!

Low-sodium beef broth: Using low-sodium versions allows you to control the saltiness while still keeping the casserole moist.
Crushed tomatoes: They add a lovely acidity and bulk to the dish. Canned tomatoes work just as well!
Worcestershire sauce: Just a splash adds a wonderful umami flavor that takes this casserole over the top.

Jasmine rice: This fragrant rice cooks beautifully, absorbing all the yummy flavors.
Monterey jack cheese: Melting this cheese on top creates an irresistible cheesy crust. Feel free to experiment with other cheeses like cheddar!
Chopped fresh parsley: This optional garnish adds a fresh note and a pop of color to your finished dish.

How to Make Stuffed Pepper Casserole

Getting from ingredients to a steaming plate of stuffed pepper casserole is a culinary journey that’ll spark joy. Let’s break it down, step by step, so you can serve this crowd-pleaser with confidence!

Step 1: Brown the Meats

Start by heating a tablespoon of olive oil in an extra-large skillet over medium-high heat.

Add in the ground beef and the mild Italian sausage, breaking them into smaller pieces with a spatula.

Cook until the meat is nicely browned, about 6 to 7 minutes, and don’t forget to stir it occasionally.

Once there’s no pink left, use a slotted spoon to transfer the meat to a plate.

This allows the flavorful fat to remain in the skillet for the next step.

Step 2: Sauté the Vegetables

Now, it’s time to add a rainbow of flavor!

In the same skillet, toss in the diced yellow onion, bell peppers, and minced garlic.

Sprinkle in the Italian seasoning blend, salt, and black pepper, too. Sauté these veggies for about 5 to 6 minutes until they’re tender and fragrant.

Step 3: Add Tomato Paste

Next, it’s time to give your veggies some extra flavor.

Stir in the tomato paste, blending it into the mixture.

Allow this to cook for another minute, letting the flavors meld together and creating a rich base for your casserole.

Step 4: Incorporate Liquid Ingredients

Now we’re ready to bring it all together!

Pour in the low-sodium beef broth, crushed tomatoes, and Worcestershire sauce.

Carefully add back the cooked meat from the plate, stirring everything to ensure even distribution.

Bring this delightful mixture up to a gentle boil.

Step 5: Add Jasmine Rice

Once boiling, it’s time to add the star of our show—jasmine rice!

Sprinkle it evenly into the boiling mixture and give it a good stir to incorporate.

This will help the rice soak up all those wonderful flavors.

Step 6: Cook and Cover

Reduce the heat to low and cover the skillet with a tight-fitting lid.

Allow it to simmer gently for 20 to 22 minutes.

Resist the urge to lift the lid too often; the steam is essential for perfectly cooked rice!

Step 7: Melt the Cheese

Once the rice is light and fluffy, remove the lid.

Stir the casserole to combine all the delicious layers, then sprinkle the shredded Monterey jack cheese evenly on top.

Place the lid back on and remove the skillet from the heat.

Let the cheese melt beautifully, creating a gooey, dreamy topping.

Step 8: Garnish and Serve

Finally, once the cheese has melted, it’s your time to shine!

Garnish your stuffed pepper casserole with chopped fresh parsley for a burst of color.

Serve it warm, and watch as it disappears faster than a magician’s rabbit!

Tips for Success

Equipment Needed

Extra-large skillet: If you don’t have one, a large pot works just as well.

Measuring cups and spoons: Essential for accuracy; you can use any available measuring tools.
Slotted spoon: Perfect for transferring meat; a regular spoon will suffice in a pinch.

Variations of Stuffed Pepper Casserole

Vegetarian version: Substitute the meats with quinoa or black beans for a heartier plant-based meal.
Spicy twist: Add diced jalapeños or crushed red pepper to kick up the heat!

Mexican-inspired: Stir in black beans and corn, topping with taco seasoning instead of Italian herbs for a flavorful twist.
