How to Make Italian Sausage with Peppers and Onions in the Oven

Italian sausages are delicious and come in a wide range of flavor options. Although they are mainly made using pork meat, you can also find them in chicken or turkey meat. Sausages are versatile and go well with many things. However, you can use them to make a quick, easy, and delicious meal. All you have to do is pair them up with bell peppers and onions and cook them in the oven.

Sausages with peppers and onions are a delicious dish that is an excellent choice for both lunch and dinner, and you can use the leftovers for breakfast as well. Although most people make this dish over a stovetop in a skillet, the easiest way to cook Italian sausages with peppers and onions is by using an oven. It is quick, convenient, and effortless.

Substitutes and variation ideas

Here are just a few ideas if you want to vary or substitute any of the ingredients in our sausage, onions, and peppers recipe.

Sausages: Although we have used mild Italian sausages for this recipe, you can replace these with sweet Italian sausages or hot Italian sausages. Sweet Italian sausages have a slightly sweet flavor, whereas hot Italian sausages are spicy. You can use chicken or turkey sausages as well. Whatever you love will work. Also, I prefer slicing the sausages before cooking the dish in the oven, but you can cook them whole.
Vegetables: You can use red, green, or yellow bell peppers or all three for this recipe. Plus, add your favorite seasonal vegetables for even more flavor. Potatoes are also delicious in this dish.
Red Wine Vinegar: Replace red wine with red wine vinegar. It will add a tangy flavor to the dish.
Pasta sauce/ crushed tomatoes: If you want to add a bit of sauce or gravy to this dish, add pasta sauce or canned crushed tomatoes for a rich, tomatoey flavor.
