Slow Cooker Sausage And Peppers

Slow cooker sausage and peppers is the kind of recipe that makes dinner feel effortless. Once the peppers, onions, seasonings, tomato sauce, and sausage are in the crockpot, the slow cooker does almost all of the work. The result is a comforting meal with rich, savory flavor and very little hands-on time.

The tomato sauce simmers with the sliced bell peppers and onions, creating a flavorful base that coats the sausages as they cook. The peppers become tender, the onions mellow, and the sausage adds a deep, satisfying taste to the sauce. Browning the sausages first is optional, but it gives them extra color and flavor before they finish cooking in the crockpot.

For a classic sausage and peppers sandwich, pile the sausage, peppers, onions, and sauce onto a sturdy steak roll or hoagie bun. The bread soaks up the sauce without needing much else on the plate. If you prefer a plated dinner, slice the sausages into bite-size pieces and serve them over rice, pasta, or mashed potatoes.

For a lighter or low-carb meal, serve crockpot sausage and peppers over cauliflower rice, alongside a salad, or simply enjoy the sausage and vegetables on their own. This recipe is flexible, filling, and easy to adapt to the way your family likes to eat.

How To Make Crockpot Sausage And Peppers

Tomato sauce is poured over peppers and onions in slow cooker.

Step One: Spray the bottom and sides of the crockpot with non-stick cooking spray.

Step Two: Cut the peppers and onion in half, then slice them lengthwise. Keep the slices at least 3/4 inch wide so they hold their shape during slow cooking. Add the sliced peppers and onion to the crockpot.

Step Three: Sprinkle the pepper, salt, dried basil, and dried oregano over the vegetables. Toss lightly with tongs to distribute the seasonings.

Step Four: Pour the tomato sauce evenly over the peppers and onions.

Step Five: Turn the crockpot to Low while you prepare the sausage.

Step Six: Heat the oil in a medium skillet over medium-high heat. Add the sausage links, cover, and cook for about 2 minutes per side, turning to brown as much of the sausage as possible. This step is optional, but it adds excellent flavor.

Step Seven: Place the browned sausage links on top of the peppers, onions, and tomato sauce in the crockpot. Cover and cook on Low for 3 to 4 hours, or until the peppers and onions are tender to your liking and the sausage is cooked through.

Step Eight: Turn the crockpot to Warm. Serve the sausage and peppers on steak rolls, hoagie buns, rice, or pasta.

Sandra’s Tips
  • Browning the sausages before slow cooking adds a caramelized, savory flavor that the crockpot alone cannot create. It is an extra step, but it is worth doing when you have time.
  • If you skip browning, make sure the sausage is fully cooked before serving.
  • To cook this recipe faster, set the crockpot to High and cook for 1 1/2 to 2 hours. Watch the peppers and onions closely so they do not become too soft.
  • Sausage links often shrink as they cook. Steak rolls can be a better fit than large sub rolls because they keep the sausage from getting lost in the bread.
  • If needed, slice the cooked sausage into 1/2-inch pieces and spoon it into rolls with plenty of peppers, onions, and sauce.
  • For game day parties or tailgating, cook the sausage and peppers at home and keep them warm in the crockpot until ready to serve.

Storage And Reheating Instructions

Store leftover crockpot sausage and peppers in an airtight container in the refrigerator for 2 to 3 days.

To reheat on the stove, place the sausage, peppers, onions, and sauce in a pan over medium heat. Add a small splash of broth or extra sauce if needed, then heat for 5 to 7 minutes, turning the sausage once, until warmed through. You can also reheat individual portions in the microwave in 30-second intervals until hot.
