This recipe shines because of its straightforward, fresh ingredients that each add a unique dimension to the casserole. From the spicy kick of Italian sausage to the sweet crunch of bell peppers, every element plays a vital role in crafting this delicious dish.

• 1 pound Italian sausage (mild or spicy): The star protein that adds rich, savory flavor and a satisfying texture.
• 2 bell peppers (red and green), sliced: These provide a colorful, sweet contrast and a tender bite.
• 1 medium onion, sliced: Adds depth and subtle sweetness when sautéed.
• 2 cloves garlic, minced: Offers bold aromatic notes that enhance the overall flavor.
• 1 can (14.5 oz) diced tomatoes, drained: Brings a juicy, tangy balance to the richness of sausage.
• 1/2 cup marinara sauce: Adds Italian flair and helps bind the ingredients together.
• 1/4 cup chicken broth: Keeps things moist and helps meld all the flavors without overwhelming.
• 1/2 teaspoon dried oregano: Infuses a classic hint of Mediterranean herbiness.
• 1/2 teaspoon dried basil: Contributes a sweet, fragrant note for authentic Italian taste.
• 1/4 teaspoon crushed red pepper flakes (optional): For those who love a little extra heat and spice.
• 1 tablespoon olive oil: Used to brown the sausage and sauté the veggies, enhancing flavor.
• 1/2 cup shredded mozzarella cheese: Melts beautifully to create a gooey, cheesy topping.
• 1/4 cup grated Parmesan cheese: Adds a sharp, savory finish to the casserole.
• Fresh parsley, chopped (for garnish): Provides a bright, fresh contrast and a pop of color.
• Salt and pepper to taste: Essential seasoning to bring all the flavors together just right.

How to Make Italian Sausage and Pepper Casserole Recipe

Step 1: Brown the Sausage

Begin by heating olive oil in a large skillet over medium heat. Add the Italian sausage and cook it until it is browned and crumbled, which takes around 7 to 8 minutes. Browning the sausage first not only deepens its flavor but also creates a wonderful texture contrast in the casserole. Once cooked, drain any excess grease and set the sausage aside temporarily.

Step 2: Sauté the Vegetables

In the same skillet, toss in the sliced bell peppers, onion, and minced garlic. Sauté them for about 5 minutes until they start to soften and release their natural sweetness. Using the same pan for the vegetables captures all the leftover sausage flavors in the veggies, tying the dish together.

Step 3: Add Tomatoes and Sauce

Next, stir in the drained diced tomatoes, marinara sauce, chicken broth, dried oregano, dried basil, and crushed red pepper flakes if you love a bit of spice. Bring this mixture to a gentle simmer for 5 to 7 minutes. Letting it simmer helps the flavors meld, creating an irresistibly rich sauce base for the casserole.

Step 4: Combine Sausage and Vegetables

Return the cooked sausage to the skillet and mix everything thoroughly. Taste and then season with salt and pepper as needed. This step ensures that all the ingredients harmonize beautifully before baking.

Step 5: Transfer to Baking Dish

Grease a 9×13-inch baking dish and pour the sausage and pepper mixture into it, spreading it evenly. This even layer is key to getting perfect baking results with melty cheese on top.

Step 6: Top with Cheese

Sprinkle shredded mozzarella and grated Parmesan cheese generously over the top. The combination of these two cheeses gives you a melty, salty crust that melts during baking to create that irresistible casserole finish.

Step 7: Bake to Perfection

Preheat your oven to 375°F (190°C). Bake the casserole for roughly 20 minutes or until the cheese is bubbly and golden. The hearty, savory scent filling your kitchen will practically invite everyone to the table.

Step 8: Serve

Once baked, garnish the casserole with freshly chopped parsley to add brightness and a lovely color contrast. Serve hot and enjoy the wonderful medley of Italian flavors that makes this dish unforgettable.

How to Serve Italian Sausage and Pepper Casserole Recipe

Garnishes

Adding a sprinkle of fresh parsley at the end not only enhances the look of your dish but also adds a fresh, slightly peppery note that balances the richness of the sausage and cheese toppings. If you want to take it up a notch, a light drizzle of good-quality extra virgin olive oil just before serving can elevate the flavors even more.

Side Dishes

This casserole pairs wonderfully with classic Italian sides like garlic bread, crusty baguettes, or a simple pasta tossed in olive oil and herbs. For something lighter, a crisp green salad with a zesty vinaigrette complements the hearty casserole beautifully.

Creative Ways to Present

For a fun twist, serve the casserole in individual ramekins or mini cast iron skillets. This presentation looks fantastic on a dinner table and makes each serving feel extra special. You can also sprinkle some toasted breadcrumbs on top before baking for an added crunchy texture.

Make Ahead and Storage

Storing Leftovers

Leftover Italian Sausage and Pepper Casserole Recipe can be stored in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen a bit as it rests, making for delicious leftovers that reheat well.

Freezing

If you want to prepare this casserole in advance, it freezes beautifully. After assembling but before baking, cover tightly with plastic wrap and foil, then freeze for up to 2 months. When ready to eat, thaw overnight in the fridge to ensure even reheating.

Reheating

Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through and the cheese is bubbly again. Alternatively, a microwave will work for a quicker option but the oven keeps the texture intact better.

FAQs

Can I use spicy Italian sausage for this casserole?

Absolutely! Spicy Italian sausage adds an extra kick to the dish, but if you prefer milder flavors, mild sausage works just as well. You can also adjust the crushed red pepper flakes to suit your heat preference.

Is this casserole gluten-free?

The recipe itself is naturally gluten-free as long as you choose gluten-free marinara sauce and broth. Always double-check ingredient labels if you have dietary restrictions.

Can I add other vegetables?

Definitely! Feel free to toss in mushrooms, zucchini, or even eggplant to boost the veggie content and introduce new flavors that complement the sausage and peppers.

What can I substitute for mozzarella cheese?

If mozzarella is not available, provolone or Monterey Jack cheese are great alternatives because they melt well and have a mild flavor that won’t overpower the dish.

How long does the casserole take to bake?

It takes about 20 minutes at 375°F (190°C) for the cheese to melt and become bubbly. If you like a crispier top, you can broil for an additional 2 to 3 minutes—just keep a close eye to avoid burning.
