The primary ingredients in Italian sausage are ground pork, garlic, and various herbs and spices, which can vary by region and producer. Typical seasonings include fennel, paprika, black pepper, and red pepper flakes, giving Italian sausage its signature savory and slightly spicy profile.

There are several distinct types of Italian sausage, including sweet, hot, and mild varieties. Sweet Italian sausage is flavored with fennel and garlic, while the hot version incorporates more red pepper for a spicier kick. Mild Italian sausage offers a more subtle flavor profile, making it a versatile option for many recipes.

Different types of Italian sausage

There are three main types of Italian sausage that is available in the grocery stores. Sweet Italian sausage, mild Italian sausage and hot Italian sausage.If you have tried my pasta con salsiccia or sausage broccolini pasta, you know I love using mild and hot Italian sausage for my recipes. Mild Italian sausage will have a little heat but nothing that is spicy.

Italian sausage can be used in many ways, from classic pasta dishes and pizza toppings to hearty soups, stews, and breakfast scrambles. Its bold taste pairs exceptionally well with complementary ingredients like tomatoes, peppers, onions, and herbs. Sliced or crumbled Italian sausage can also be a flavorful addition to stuffing, casseroles, and even sandwiches.

Exploring the nuances of Italian sausage and its many culinary applications can inspire home cooks and professional chefs to incorporate this beloved ingredient into diverse recipes.

Sweet vs. Hot Italian Sausage

The type of sausage that we are referring to here is fresh pork sausage that is made with Italian seasonings. “Hot” Italian sausage has red pepper flakes added, whereas “sweet” does not contain any hot pepper. Italian sausage may or may not contain whole fennel seeds as well.

There is another form of Italian sausage called Italian ring sausage, or chevalatta. It is made with a sheep casing and is, therefore, much thinner than traditional Italian sausage. It’s often seasoned with parsley and Pecorino Romano cheese and is generally only found at Italian butchers and shops. This type of sausage can be baked according to the recipe below, but will take less time since it is so much smaller.

I love to bake Italian sausage for a last minute dinner–a great reason to always have some on hand in the freezer! In a pinch, you can use it in lots of recipes, such as Artichoke Sausage Pasta with Lemon and Basil, to really cut down on cooking time.

Preparing Italian Sausage for Oven Cooking

When preparing Italian sausage for oven cooking, there are a few key steps to ensure optimal flavor and texture.

First, remove the sausage from its casing. This allows the sausage to cook more evenly and develop a nice crust. If you prefer to keep the casing on, prick it with a fork to allow the juices to escape during cooking.

Next, season the sausage as desired. A classic Italian seasoning blend of garlic, fennel, paprika, and red pepper flakes works well. You can also try marinating the sausage in olive oil, red wine vinegar, and herbs for extra flavor.

Once seasoned, arrange the sausages in a single layer on a baking sheet or a shallow roasting pan. Leave a bit of space between each piece to allow for even browning.

Roast the sausages in a preheated oven at 400°F for 20-25 minutes, flipping halfway through, until they reach an internal temperature of 165°F. This oven method produces juicy, flavorful Italian sausage that pairs perfectly with pasta, peppers, onions, or crusty bread.
