FAQs & Tips
What type of sausage should you use?
This easy crockpot recipe calls for smoked sausage. Smoked sausage is already cooked. When it comes to the type of smoked sausage, that’s up to you. I use a generic smoked sausage but other suggestions include kielbasa or andouille sausage. Note, the type of sausage you use may alter the taste of the dish. For a list of Whole30 compatible sausages, see HERE.
What type of bell peppers should you use?
You do not need to use 3 different colored bell peppers. All green bell peppers will work just fine.
Is this enough liquid?
It may not seem like there is enough liquid in the slow cooker when it starts cooking because the food will not fully be submerged. This is normal. Trust me, you do not need to add any additional broth or tomatoes. Unless you want to turn this into a soup.
How do you serve this?
I served mine with rice but it will all depend on your dietary restrictions. For Whole30, paleo, or low-carb I suggest serving this over cauliflower rice, zoodles, or mashed cauliflower. Other options include mashed potatoes, rice or pasta.
How do you store leftovers?
Store leftover slow cooker sausage, bell pepper, and onions in the refrigerator for up to 4 days.
What size slow cooker should you use?
I used a 6-quart slow cooker or Instant Pot.

Is this a keto friendly diet ???
Hi! Will be making this tomorrow. Just curious have you ever made it in a dutch oven? If yes, how long did you cook it and what setting on the stove? Thanks ??
Am I reading correctly that in an instantpot this only cooks for 7 minutes?
Sausage onion peppers started and I cant wait to sit down with the family later to enjoy it. Will let you know how it turns out!. Thanks for a great recipe!
I have made this twice now and I have to tell you, my family absolutely loves it! I serve it over rice. It’s in regular rotation, thank you!
You’re welcome! I’m so happy to hear you & the fam enjoy it!
Hi, I have the Insta pot Duo Nova, am I reading correctly that it only take about 7 minutes to make this meal?
Just got this one going in the crockpot! I did not have the chicken broth so I just used water. So far everything I’ve tried from this site is amaze!
I hope you enjoyed it!
Absolutely amazing!
When you say slow cooker are you using the instapot on the slow cooker setting or using a different crock pot all together?
No, I do not use the IP’s slow cooker function. When I say slow cooker I mean an actual slow cooker yes like the brand Crock-pot.
This looks hearty & healthy! NICE
