Here are the ingredients you'll need to make this sausage and peppers Crockpot recipe:
Please see the recipe card for exact quantities.

Equipment and tools needed to make this recipe:
- 4 Quart Slow Cooker
- Cutting Board

Here are a few ways you can vary or make substitutions to this recipe:
- You can use mild, hot, or sweet Italian sausage. If you are following keto or watching your sugar intake do not use the sweet Italian sausage.
- Give this a cajun spin instead. Substitute a cajun sausage, use cajun seasoning, and instead of marinara sauce use diced tomatoes with onion and bell peppers. Due to the salt in cajun seasoning, do not add salt and pepper until you are ready to serve and only if needed.
- Is the sauce too runny? Thicken it with a little cornstarch or xanthan gum. If using xanthan gum use about 1/4 teaspoon dissolved in 1 teaspoon of olive oil. A little goes a long way!
