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 your Italian sausage, whether sliced or removed from its casing, and cook until it’s nicely browned and cooked through, about 6 to 8 minutes. The sausage will release flavorful fats that will enrich the dish, so don’t rush this step. Once browned, transfer the sausage to a plate and set aside to rest while you prepare the vegetables.
Step 2: Sauté the Vegetables
In that same skillet, toss in the sliced red, yellow, and green bell peppers along with the red onion. Cook them gently until they’re tender yet still vibrant, about 5 minutes. Then add the minced garlic, Italian seasoning, salt, and pepper, cooking for about one more minute to let those wonderful aromatics bloom and integrate with the vegetables.
Step 3: Combine Tomato Elements
Stir in the drained diced tomatoes and the marinara sauce into the vegetable mixture. Let it simmer for 2 to 3 minutes so the flavors meld together and the mixture slightly thickens. This rich, tomatoey base is what brings everything together in the casserole, giving it a comforting, saucy heart.
Step 4: Mix Pasta, Sausage, and Vegetables
In a large mixing bowl, combine the cooked pasta, browned sausage, and the pepper-tomato sauce mixture. Stir everything thoroughly to ensure every bite is bursting with balanced flavor. This step is crucial for an even distribution of ingredients before baking.
Step 5: Assemble and Bake
Transfer the mixture into a greased 9×13-inch baking dish, spreading it out evenly. Generously sprinkle the shredded mozzarella cheese and grated Parmesan over the top. Pop it into a preheated oven at 375 degrees Fahrenheit and bake uncovered for 20 to 25 minutes until the cheese melts into a golden, bubbly masterpiece that’s hard to resist.
Step 6: Garnish and Serve
Once out of the oven, let the casserole rest for a few minutes. Then, if you like, sprinkle fresh basil or parsley over the top for a gorgeous, fresh touch and slightly herbaceous aroma that brightens each cheesy, sausage-filled spoonful.
How to Serve Italian Sausage and Pepper Casserole Recipe
Garnishes
Fresh herbs like basil or parsley add a delightful burst of color and a fresh, aromatic note that compliments the savory casserole beautifully. A light drizzle of extra virgin olive oil or a pinch of red pepper flakes can also add subtle layers of flavor and heat.
Side Dishes
This casserole is hearty enough to stand on its own, but if you want to round out the meal, consider a simple mixed green salad with vinaigrette or some crusty garlic bread to soak up every last bit of the delicious sauce. Roasted vegetables or a light antipasto plate would also complement the Italian flavors wonderfully.
Creative Ways to Present
For a fun twist, serve the casserole family-style straight from the baking dish in the center of the table. You can also scoop portions into individual ramekins or bake the casserole in smaller dishes for a personalized presentation. Adding a sprinkle of toasted pine nuts or a few olives on top before serving can offer a new texture and flavor dimension.
Make Ahead and Storage
Storing Leftovers
Leftovers are a gift with this Italian Sausage and Pepper Casserole Recipe. Simply cover the casserole tightly with plastic wrap or foil and store in the refrigerator for up to 3 days. The flavors actually deepen overnight, making for even better taste the next day.
Freezing
You can freeze this casserole if you want to save it for an even later date. Assemble the casserole following the recipe, then cover it well with foil and freeze for up to 2 months. Thaw it in the refrigerator overnight before baking, then follow the baking instructions, adding a few extra minutes if needed for thorough heating.
Reheating
Reheat individual portions in the microwave until warmed through, or if you have more time, warm the entire casserole in the oven at 350 degrees Fahrenheit until hot and bubbly again. Adding a sprinkle of cheese before reheating can revive that fresh-from-the-oven appeal.
FAQs
Can I use turkey or chicken sausage instead of Italian sausage?
Absolutely. Using turkey or chicken sausage is a great way to reduce fat without sacrificing flavor. Just opt for good-quality sausages with Italian seasoning to keep the dish authentic and tasty.
What type of pasta works best in this casserole?
Penne or ziti are the traditional choices because their tubular shapes hold onto the sauce well. However, rigatoni, rotini, or even fusilli will work perfectly too!
Is this recipe suitable for meal prep?
Definitely! This Italian Sausage and Pepper Casserole Recipe is perfect for making ahead. Prepare the casserole up to the baking step, then refrigerate or freeze. When ready to eat, just pop it in the oven and enjoy a warm, home-cooked meal with minimal effort.
Can I make this low-carb?
Yes! For a low-carb version, substitute the pasta with roasted cauliflower or zucchini noodles. Both options absorb the flavors wonderfully and keep the casserole hearty yet lighter.
How spicy is this casserole if I use spicy Italian sausage?
The heat level depends on your sausage choice. Spicy Italian sausage gives the casserole a nice kick, balanced by the sweetness of the bell peppers and tomatoes. If you prefer less heat, stick to sweet Italian sausage or adjust with a milder sausage.
