Ingredients You’ll Need

This section explains how to choose the best ingredients for Italian sausage, peppers, and onions, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

  • Olive Oil For sauteing the sausages before slow cooking. You can skip the browning if you’re really in a rush, but I promise it’s worth it if you can brown the sausages first. It only takes a couple of minutes and adds so much flavor. Any other cooking oil, such as avocado oil, is fine to use here.
  • Sausages – I used mildly spicy pork Italian sausage links, but any kind of sausage will work, including sweet Italian sausage, turkey sausage, kielbasa, or bratwurst.
  • Bell Peppers – Cut them into strips, like you would for fajitas. I used one each of orange, yellow, and red bell peppers, but any colors you like are great.
  • Onion – This Crock Pot recipe for Italian sausage, peppers, and onions will work great with any type of onion. I used white onion in this dish, but feel free to use what you have on hand – red, white, or yellow. Slice the onion into half moons, the same width as the pepper strips.
  • Garlic – Mince fresh garlic cloves for best flavor, or use jarred garlic for convenience.
  • Italian Seasoning – I used my 5-minute homemade Italian seasoning, which is a combo of dried oregano, basil, marjoram, thyme, rosemary, and sage. Store bought will work just fine, though. If you like some heat, add a dash of red pepper flakes to the seasoning.
  • Sea Salt & Black Pepper
  • Marinara Sauce – I used homemade marinara, which is quick and easy to make, but store bought is fine to use. You can also substitute crushed tomatoes or tomato sauce, but may need to adjust the salt or seasonings.
