How to Make Stuffed Pepper Casserole

Creating a Stuffed Pepper Casserole is a straightforward process that yields delicious results. Follow these simple steps, and you’ll have a hearty meal ready in no time!

Step 1: Preheat the Oven

Start by preheating your oven to 350°F. This step is crucial for even cooking. A hot oven ensures that your casserole bakes uniformly, giving you that perfect golden finish.

Step 2: Brown the Meat

In a large skillet over medium heat, add your ground beef or turkey. Toss in the diced onion and minced garlic. Cook until the meat is browned and the onions are translucent. This usually takes about 5-7 minutes. Don’t forget to drain any excess fat! This keeps your casserole from becoming greasy and allows the flavors to shine.

Step 3: Combine Ingredients

Now, stir in the diced tomatoes, tomato sauce, uncooked elbow macaroni, and water. Sprinkle in the Italian seasoning, salt, and black pepper. Bring this mixture to a boil, then reduce the heat and let it simmer for 10–12 minutes, or until pasta is nearly tender; it will finish cooking in the oven. This simmering step is key; it allows the pasta to absorb all those wonderful flavors while becoming tender.

Step 4: Prepare the Bell Peppers

While the pasta mixture simmers, it’s time to prepare the bell peppers. Cut them in half lengthwise and remove the seeds. Arrange the halved peppers cut-side up in a 9×13 inch baking dish. This not only looks great but also makes filling them a breeze!

Step 5: Fill the Peppers

Once your pasta mixture is ready, it’s time to fill those peppers! Spoon the mixture evenly into each halved bell pepper. This ensures every bite is bursting with flavor.

Step 6: Bake Covered

Sprinkle half of the Parmesan cheese over the filled peppers before covering with foil. Cover the baking dish with aluminum foil and pop it in the oven. Baking it covered for the first 30 minutes helps steam the peppers, making them tender while keeping the filling moist. It’s a little trick that makes a big difference!

Step 7: Add Cheese and Bake Uncovered

After 30 minutes, remove the foil and sprinkle remaining half of the Parmesan cheese and the shredded mozzarella on top of the stuffed peppers. Return the dish to the oven and bake uncovered for an additional 10-15 minutes. This final step is where the magic happens—the cheese melts and bubbles, creating a deliciously gooey topping that ties everything together.

Tips for Success

  • Use fresh ingredients for the best flavor—especially the bell peppers and herbs.
  • Use red, orange, or yellow bell peppers for a sweeter flavor; green is more savory and slightly bitter.
  • Don’t overcook the pasta in the skillet; it will continue to cook in the oven.
  • Experiment with different cheeses like cheddar or pepper jack for a unique twist.
  • Let the casserole cool for a few minutes before serving; it helps the flavors settle.
  • If the filling seems too watery after simmering, allow it to cook a few more minutes uncovered to reduce excess liquid before filling the peppers.
  • For leftovers, store in an airtight container for up to three days.

Equipment Needed

  • Large skillet: A non-stick skillet works best, but any large pan will do.
  • Baking dish: A 9×13 inch dish is ideal; you can use any oven-safe dish.
  • Aluminum foil: Essential for covering the dish while baking.
  • Measuring cups: Handy for precise ingredient portions.
  • Wooden spoon: Perfect for mixing and stirring the ingredients.

Variations

  • Vegetarian Delight: Swap the ground meat for a mix of black beans and chopped mushrooms for a hearty vegetarian option.
  • Spicy Kick: Add a teaspoon of crushed red pepper flakes to the meat mixture for an extra layer of heat.
  • Cheesy Goodness: Experiment with different cheeses like sharp cheddar or pepper jack for a unique flavor twist.
  • Quinoa Boost: Substitute elbow macaroni with cooked quinoa for a gluten-free and protein-packed alternative.
  • Herb Infusion: Fresh herbs like basil or parsley can be added for a burst of freshness and flavor.

Serving Suggestions

  • Side Salad: Pair your casserole with a fresh garden salad for a refreshing crunch.
  • Garlic Bread: Serve with warm garlic bread to soak up the delicious sauce.
  • Wine Pairing: A light red wine, like Pinot Noir, complements the flavors beautifully.
  • Presentation: Garnish with fresh parsley or basil for a pop of color.
