Slow Cooker Sausage and Peppers

Jump to Recipe

This slow cooker sausage and peppers recipe lets everything simmer together for hours until the sausage is tender and the peppers have softened into the sauce. Set it and forget it, mostly.

It's a good weeknight meal for a busy day, served over rice or on a hoagie roll. Brown your sausage first if you have time — it adds real depth.

Pro Tips

  • Searing the sausages first adds a layer of flavor the slow cooker alone can't achieve.
  • Use a mix of colored peppers for visual appeal — red, yellow, and green.
  • The peppers become silky and sweet after hours of cooking. That's the whole point.

Substitutions

Italian sausage → bratwurst or chicken sausage Chicken sausage is lighter; bratwurst is a German twist.
hoagie rolls → polenta, rice, or pasta Serve over polenta for a more refined presentation.
diced tomatoes → marinara sauce for a saucier version More sauce means better sandwich dripping.

Storage Instructions

Refrigerate for up to 4 days. Reheat gently.

Make Ahead

Prep all vegetables the night before. Assemble in the slow cooker in the morning.

Freezing

Yes. Freeze the cooked sausage, pepper, onion, and tomato mixture in airtight portions. Thaw in the refrigerator, reheat thoroughly, and serve it on fresh hoagie rolls.
