How to Make Flavorful Italian Sausage & Pepper Casserole
Prepare Your Ingredients: Start by chopping your bell peppers and onion into bite-sized pieces while mincing fresh garlic. Preheat your oven to 375°F (190°C) so it’s hot and ready when needed.
Sauté the Sausage: In a large skillet over medium heat, cook the sliced Italian sausage until browned and crispy, about 5-7 minutes. This step releases those irresistible flavors that waft through your kitchen.
Add the Veggies: Toss in your chopped bell peppers and onion once the sausage is nicely browned. Sauté until they soften, about 4-5 minutes, keeping an eye out for that lovely caramelization.
Incorporate Garlic & Tomatoes: Stir in minced garlic along with canned diced tomatoes—let this simmer for about 3-4 minutes until everything melds together beautifully.
Add Seasoning & Cheese: Sprinkle in Italian seasoning along with salt and pepper to taste; stir well. Then mix in shredded cheese if you desire extra creaminess before transferring everything to a baking dish.
Bake Until Golden: Spread your mixture evenly in a baking dish and top with more cheese if you like—bake uncovered for 25-30 minutes until bubbly and golden brown on top. Enjoy watching it transform into a mouthwatering masterpiece!
