The Ingredients
Italian Sausage: I use sweet Italian sausage for extra flavor, but hot sausage works great if you like spice.
Bell Peppers: A mix of red, yellow, and green peppers adds color and sweetness—slice them into strips.
Yellow Onion: Two small sweet onions, sliced, add heartiness and depth.
Marinara Sauce: Use a 24 oz. jar of your favorite marinara.
Garlic: Four cloves give this dish bold, savory flavor.
Seasonings: A simple sprinkle of salt and pepper ties everything together.
How to make Crockpot Sausage and Peppers
- Prep your ingredients by slicing the veggies and gathering everything you need.
- Add it all to the crockpot—the sausage, peppers, onions, garlic, and sauce.
- Let it slow cook until the sausages are tender and the flavors have melded.
- Slice and serve over rice, mashed potatoes, or however you like.
Sarah’s Tips and Varitations
- Two cans of diced tomatoes can be used instead of the marinara.
- Turkey sausage, spicy Italian sausage, hot Italian sausage, ground sausage, or beef sausage would all be great substitutions.
- The sausage can be browned in a skillet before adding to the slow cooker.
- Mushrooms, zucchini, or even cherry tomatoes can be tossed in with the peppers and onions.
- A splash of beer or red wine will add depth of flavor to the dish.
- Add some Italian flavor by adding dried basil, dried oregano, red pepper flakes, or Italian seasoning.
Serving Suggestions
- One of the most popular ways to serve this pepper recipe is over mashed potatoes or white rice.
- A drained helping can also be put onto a hoagie roll or hoagie buns.
- Turn it into a pasta dish by mixing it with cooked penne pasta.
