Step‑by‑Step Instructions for Italian Sausage & Pepper Casserole

Step 1: Prep Ingredients
Begin by chopping your bell peppers and onion into bite-sized pieces, and mince the garlic to unleash its aroma. Preheat your oven to 375°F (190°C), ensuring it's ready for the final bake. Gather all your ingredients and equipment, including a large skillet and a baking dish, for a seamless cooking experience.

Step 2: Sauté Sausage
In a large skillet, place the sliced Italian sausage over medium heat. Cook for 5-7 minutes, stirring occasionally, until the sausage is beautifully browned and crispy, releasing its savory oils. This browning process is key to adding depth of flavor to your Italian Sausage & Pepper Casserole.

Step 3: Add Vegetables
Once the sausage is browned, mix in the chopped bell peppers and onions. Sauté the mixture for another 4-5 minutes, observing how the vegetables soften and become more vibrant in color. This step enhances the casserole's flavor, ensuring each bite is filled with deliciousness.

Step 4: Incorporate Flavors
Add the minced garlic and canned diced tomatoes to the skillet, stirring everything together. Allow the mixture to simmer for 3-4 minutes, letting the flavors meld beautifully. Keep an eye on the mixture as it cooks; you'll know it's ready when the tomatoes are heated through and fragrant.

Step 5: Season & Transfer
stir in the Italian seasoning, along with salt and pepper to taste, adjusting based on your preference. If you wish, mix in your favorite cheese for extra creaminess. Once well combined, pour the savory mixture into a baking dish, spreading it evenly to prepare for baking.

Step 6: Bake
Place the baking dish in the preheated oven and bake uncovered for 25-30 minutes. Keep an eye on it as it cooks, waiting for the top to become bubbly and golden brown. This final step is crucial for achieving that irresistible casserole finish, bringing the comforting Italian Sausage & Pepper Casserole to life.
