This will take you through how to make this delicious spaghetti with kielbasa, peppers, and onions step-by-step. Let’s get started!

Ingredients for Spaghetti with Kielbasa, Peppers, and Onions

Kielbasa – Use whatever kind of kielbasa you like. Depending on what brand you choose the package size can vary from 12-16 ounces.

Peppers – I like to use a red and green bell pepper but you can also use two green peppers or whatever color you prefer.

Onion – A large onion adds a mild sweetness.

Garlic – This recipe calls for 3 cloves of fresh garlic, and it gives the sauce a lot of its flavor. You can certainly use more than this if you really like garlic!

Basil, Cayenne pepper, and Salt – The basil adds flavor and the cayenne adds a subtle heat. You can adjust these to taste.

Oil – I use olive oil, but any cooking oil will do.

Spaghetti – I usually use plain spaghetti but feel free to experiment with other pasta shapes.
