Ingredients

Here’s the magic of this casserole—it’s made with simple, everyday ingredients that come together to create something truly irresistible. Let’s break it down:

Italian Sausage

The star of the show! The savory, juicy sausage brings so much flavor and depth to this casserole. You can use mild or spicy, depending on your preference. The sausage infuses the whole dish with its rich, herby goodness.

Bell Peppers

Sweet, tender bell peppers add a burst of color and a hint of sweetness that pairs perfectly with the savory sausage. You can use red, yellow, or green—whichever you prefer!

Onion

A little bit of onion brings out that comforting, savory flavor that ties everything together. When it’s cooked, it softens and becomes sweet and aromatic.

Mozzarella Cheese

Cheese, glorious cheese! Mozzarella adds a melty, gooey layer of perfection. It melts beautifully over the sausage and peppers, making every bite so satisfying.

Marinara Sauce

Rich, tomatoey marinara sauce is the glue that holds everything together. It’s the perfect complement to the savory sausage and veggies, giving the casserole a luscious, saucy texture.

(Note: The full ingredients list, including measurements, is provided in the recipe card directly below.)

Instructions

Now let’s get cooking! Here’s how to make this flavorful casserole:

Preheat Your Oven

Start by preheating your oven to the right temperature. This ensures everything cooks evenly and comes out with the perfect texture.

Cook the Sausage

In a skillet, cook your Italian sausage until it’s nice and browned. Break it apart as it cooks, so you get those crispy, savory bits that make this dish even more irresistible.

Sauté the Vegetables

In the same skillet, toss in your bell peppers and onions. Sauté them until they’re tender and just starting to caramelize. The aroma will be enough to make your stomach growl!

Layer the Casserole

In a greased baking dish, layer your sausage, peppers, onions, and marinara sauce. Top it off with a generous amount of mozzarella cheese. Trust me, the more cheese, the better!

Bake to Perfection

Pop the casserole in the oven and bake until the cheese is melted and bubbly. The casserole will come out golden and delicious, with all the flavors beautifully melded together.

Let It Cool

As tempting as it is to dig in right away, give the casserole a few minutes to cool. This helps the flavors settle and makes serving a bit easier.

Serve and Enjoy

Scoop yourself a hearty portion, and enjoy this comforting meal that’s sure to warm your heart!

How to Serve Italian Sausage and Pepper Casserole

This casserole pairs wonderfully with a variety of sides to round out the meal. Here are a few ideas to make your dinner complete:

Fresh Salads

Pair it with a light, refreshing green salad. The crispness of the salad contrasts perfectly with the richness of the casserole.

Crusty Bread

Serve with some warm, crusty bread to soak up all the extra sauce. A baguette or garlic bread works wonders here.

Creamy Accompaniments

A dollop of sour cream or a drizzle of ranch dressing on the side can add a creamy touch that complements the casserole’s savory flavors.

Roasted Vegetables

A side of roasted vegetables—like carrots, zucchini, or asparagus—adds color and nutrition to the meal, making it even more satisfying.

As a Standalone

Sometimes, this casserole is hearty enough to stand on its own. Serve it with a simple garnish of fresh herbs like basil or parsley to add a pop of color.

Additional Tips

Here are a few extra tips to make your Italian Sausage and Pepper Casserole even better:

Prep Ahead

Save time by chopping and measuring your ingredients the night before. That way, when it’s time to cook, all you need to do is assemble and bake!

Spice It Up

Feeling adventurous? Add some chili flakes, smoked paprika, or even a bit of cayenne pepper to give the casserole a little kick.

Dietary Adjustments

If you need to make this dish a bit lighter, you can use turkey sausage instead of pork sausage. For a dairy-free version, swap out the cheese for a non-dairy alternative.

Storage Tips

Store leftovers in an airtight container in the fridge for up to 3-4 days. Reheat in the oven for the best results.

Double the Batch

This recipe freezes beautifully. Make a double batch and freeze one for a busy night when you don’t feel like cooking!
