Dump-and-Bake Italian Sausage Casserole

You don’t even have to boil the pasta for this easy dump-and-bake Italian sausage casserole! With only 5 ingredients and 5 minutes of prep, family-friendly weeknight dinners don’t get much better than this.

So many of you regularly tell me how much you rely on my dump-and-bake recipes to help you get weeknight meals on the table. This Italian sausage casserole is just the latest in our lineup of favorites, which include other family-friendly dinners like dump-and-bake chicken Alfredo pasta, dump-and-bake chicken broccoli rice casserole, and this dump-and-bake meatball casserole.

Do you have to cook pasta before putting it in a casserole?

While most casserole recipes call for cooking the pasta before mixing it into the dish, this particular recipe is designed specifically for uncooked pasta. That means that you do not boil the noodles in a saucepan on the stovetop before adding them to the casserole dish.

Instead, the pasta cooks right in the oven with the rest of the ingredients. This requires extra liquid in the pan (since the pasta absorbs a lot of liquid as it cooks), and extra cooking time to make sure that the noodles are tender.

Serving Suggestions

Serve this easy Italian sausage casserole with any of these sides:

• Garlic bread, homemade focaccia, no-knead cast iron focaccia, breadsticks, or a crusty loaf of no-knead Dutch oven bread
• Green salad with red wine vinaigrette, mixed greens with Dijon vinaigrette or balsamic vinaigrette, creamy Caesar salad, or a classic Caesar salad
• Tomato salad with basil and balsamic
• Cucumber, tomato, and onion salad
• Parmesan roasted cauliflower
• Roasted broccoli or asparagus
• Sauteed asparagus
• 3-ingredient roasted yellow squash or sauteed zucchini
• 2-ingredient Italian sugar snap peas
• Brown sugar glazed carrots
• Fennel salad with apples and creamy cider dressing

Recipe Variations

• Don’t have rotini? You can substitute with other similar short pasta shapes such as penne, rigatoni, ziti, or elbows. Just pick a pasta that has a similar cooking time as the rotini (about 7-8 minutes recommended on the package) — otherwise you’ll need to adjust the casserole’s baking time in the oven.
• Replace some of the water with ½ cup of red wine.
• Stir in some veggies. Good options include sliced fresh mushrooms, thawed frozen broccoli florets, grated zucchini, fresh baby spinach, or oil-packed sundried tomatoes.
• Give the dish more flavor by including 2 teaspoons of Italian seasoning, ½ teaspoon crushed red pepper flakes, ½ teaspoon garlic powder, and ¼ teaspoon onion powder.
• Add buttered breadcrumbs on top for a crunchy texture.
• Instead of Italian sausage, use ground beef (that you brown in a skillet first), or try frozen Italian meatballs (that you thaw first).
• Cooking for a Smaller Family: Cut all of the ingredients in half and bake the casserole in an 8-inch square pan. Check the pasta after 30 minutes, as it may be done slightly sooner than the larger pan.
• If you don’t have a broiler, just return the casserole (uncovered) to the oven and bake for 5-10 minutes until the cheese melts.

Tips for the Best Italian Sausage Casserole Recipe

• Use a large 13 x 9-inch dish with a capacity of at least 3 – 4 quarts so that it can accommodate all of the raw ingredients without bubbling over. Be sure to check out our roundup of the best casserole dishes.
• Pick a high-quality, flavorful marinara sauce. A delicious sauce will yield a delicious meal. I like Rao’s brand, but any similar variety will work.
• Total cooking times will vary depending on the type of pan that you use, your brand of pasta, and your individual oven. Glass or ceramic baking dishes will take longer than metal pans, for instance. To know when your casserole is done, taste a bite of the pasta. The noodles should be tender and much of the liquid should be absorbed.
• Be careful not to overbake the casserole or the pasta will become mushy.
• Garnish the casserole with herbs like fresh basil or fresh parsley for a bright, colorful touch.

Equipment

• 1 9 x 13-Inch Baking Dish

Ingredients

  

1x2x3x

• 3 cups water
• 1 (24 or 25 ounce) jar marinara sauce
• 1 (16 ounce) package uncooked rotini pasta
• 1 lb. fully-cooked Italian sausage links, sliced into rounds (we like Aidell's brand or this Good & Gather brand)
• 8 ounces (about 2 cups) shredded Italian cheese blend or shredded mozzarella cheese
• Kosher salt and ground black pepper, to taste
• Optional garnish: chopped fresh herbs such as parsley, basil, or thyme

Instructions

• Preheat oven to 425°F. Lightly coat a 9 x 13-inch baking dish with nonstick cooking spray.
• In the prepared dish, whisk together the water, marinara sauce, ½ teaspoon of kosher salt, and ground black pepper to taste. Add the uncooked pasta and the sliced sausage. Use your hands or a wooden spoon to combine the ingredients and evenly distribute the pasta and sausage throughout the pan. Cover tightly with aluminum foil and bake for 35 minutes.
  
• Uncover; stir gently with a fork. At this point, you should check the pasta to make sure that it is al dente (tender, but with a firm bite). If the pasta is still too hard, cover the dish and return it to the oven until the pasta is al dente. The move on to the next step.
  
• Sprinkle the cheese over top. Transfer the uncovered dish to the broiler for about 1-2 minutes, just until the cheese melts and starts to brown on top. Keep a close eye on the dish the entire time since the cheese can burn quickly under the broiler.
  
• Garnish with chopped fresh herbs, if desired. Serve immediately.
