Techniques Required

How to brown the sausage: Cook the sausage over high heat in a large non-stick skillet, breaking it up into smaller pieces as it cooks until it is cooked through and browned.

How to sauté the vegetables: In a skillet, heat olive oil over medium heat and add the onions, garlic, and peppers. Sauté for about 6 to 7 minutes until the vegetables are soft.

How to simmer the sauce: After adding the sausage back to the skillet with the vegetables, bring the mixture to a boil, then lower the heat to medium-low and simmer for 10 minutes until the vegetables are soft.

How to assemble the casserole: Spoon just enough of the sausage/vegetable mixture to cover the bottom of a 9x13-inch pan. Cover with uncooked pasta, spoon the remaining sauce mixture evenly over the top, and sprinkle with cheese.

How to bake the casserole: Cover the casserole with foil and bake at 350 degrees F for 50 to 55 minutes. Remove from the oven and let it stand covered for 15 minutes before serving.

Technique Tip for Perfecting Sausage and Peppers Macaroni Casserole

When browning the chicken sausage, make sure to break it up into small pieces as it cooks. This will not only ensure that the sausage is cooked evenly, but also allow it to distribute more evenly throughout the casserole, giving every bite a perfect balance of flavors. Additionally, when sautéing the onions, garlic, and peppers, be patient and let them soften properly. This will bring out their natural sweetness and add depth to the overall flavor of the dish.

Time-Saving Tips for Making Sausage and Peppers Macaroni Casserole

Prep ahead: Chop vegetables and sausage in advance to save time during the cooking process.

One-pot wonder: Consider using a large skillet or pot to cook the entire dish in one vessel, reducing the number of dishes to clean.

Batch cooking: Make a larger portion and freeze individual servings for quick and easy meals in the future.

Use pre-cooked sausage: Opt for pre-cooked sausage to skip the browning step and save time.

Multitask: While the casserole is baking, use that time to clean up the kitchen or prepare a simple side salad.

How To Store and Freeze This Casserole

  • Allow the casserole to cool completely before storing or freezing. This will prevent condensation from forming and making the dish soggy.

  • For short-term storage, cover the casserole tightly with plastic wrap or aluminum foil and refrigerate for up to 3-4 days.

  • To freeze the casserole:

    • Divide the cooled casserole into individual portions or freeze the entire casserole in a freezer-safe container or aluminum tray.
    • If using a container, make sure to leave some space at the top for expansion during freezing.
    • Wrap the container or tray tightly with plastic wrap, followed by a layer of aluminum foil to prevent freezer burn.
    • Label the container or tray with the dish name and date of freezing.
    • Freeze for up to 2-3 months for best quality.
  • To reheat the frozen casserole:

    • If reheating individual portions, thaw the desired number of portions overnight in the refrigerator.
    • For reheating the entire casserole, you can either thaw it overnight in the refrigerator or place it directly in the oven from the freezer.
    • Preheat the oven to 350°F (175°C).
    • Remove the plastic wrap and cover the casserole with aluminum foil.
    • If thawed, bake for 20-30 minutes or until heated through. If frozen, bake for 45-60 minutes or until heated through and bubbly.
    • Remove the foil for the last 5-10 minutes of baking to allow the top to brown slightly.
  • When reheating, ensure that the internal temperature of the casserole reaches 165°F (74°C) to ensure food safety.

  • If you have any leftover sausage, peppers, or onions, you can store them separately in airtight containers in the refrigerator for up to 3-4 days. These can be used as toppings for the reheated casserole or in other dishes like omelets, sandwiches, or quesadillas.

How To Reheat Leftovers

  • Preheat your oven to 350°F (175°C). Place the leftover sausage and peppers macaroni casserole in an oven-safe dish and cover it with aluminum foil. Bake for 20-25 minutes, or until the casserole is heated through and the cheese is melted and bubbly. This method ensures that the casserole heats evenly and the cheese melts perfectly, creating a delicious, comforting meal.

  • If you prefer a quicker reheating method, you can use your microwave. Transfer individual portions of the casserole to microwave-safe plates and heat them on high power for 1-2 minutes, or until the casserole is heated through. Be sure to stir the casserole halfway through the reheating process to ensure even heating. While this method is faster, keep in mind that the texture of the pasta and cheese may change slightly due to the microwave's quick heating process.

  • For a crispy top layer, you can reheat the sausage and peppers macaroni casserole under the broiler. Preheat your broiler to high and place the casserole in an oven-safe dish. Broil for 2-3 minutes, or until the cheese is melted and golden brown. Keep a close eye on the casserole while it's under the broiler, as it can burn quickly. This method adds a delightful crunch to the top of the casserole, making it even more satisfying to eat.

  • If you have a toaster oven, you can use it to reheat smaller portions of the casserole. Preheat the toaster oven to 350°F (175°C) and place a single serving of the casserole in an oven-safe dish. Heat for 10-15 minutes, or until the casserole is heated through and the cheese is melted. This method is perfect for those times when you're craving a comforting meal but don't want to heat up your entire oven.

  • For a stovetop reheating option, transfer the leftover sausage and peppers macaroni casserole to a large skillet or saucepan. Add a splash of water or chicken broth to help loosen the sauce and prevent the pasta from drying out. Heat the casserole over medium heat, stirring occasionally, until it's heated through and the cheese is melted. This method allows you to easily control the moisture content of the casserole and ensures that the pasta remains tender and flavorful.
