Step-by-Step Instructions

Making Slow Cooker Italian Sausage and Peppers is incredibly easy! Follow these steps for a flavorful, hands-off meal.

Step 1: Prep the Ingredients

Slice 2 bell peppers and 1 onion into thin strips.
Mince 3 garlic cloves.
If sausages are in casings, leave them whole or cut into smaller pieces for easier serving.
Tip: Keep veggie slices similar in size for even cooking.

Step 2: Combine in the Slow Cooker

Place 1.5 lbs Italian sausage in the bottom of the slow cooker.
Add sliced bell peppers, sliced onion, minced garlic, 1 can (14 oz) undrained diced tomatoes, 1 tsp dried oregano, 1 tsp dried basil, and a pinch of salt and pepper.
Stir gently to combine, ensuring the sausages are coated and the veggies are evenly distributed.
Tip: Nestle the sausages into the sauce to keep them moist during cooking.

Step 3: Cook

Cover and cook on low for 6–7 hours or high for 3–4 hours, until the sausages are cooked through (internal temperature of 160°F/71°C for pork) and the vegetables are tender.
Stir halfway through if possible to blend the flavors.
Tip: If the sauce is too thin, remove the lid for the last 30 minutes on high to reduce it.

Step 4: Serve

For sandwiches, place a sausage in a crusty roll, top with peppers, onions, and sauce, and garnish with fresh parsley.
For pasta, spoon the sausage, veggies, and sauce over cooked pasta (like penne or spaghetti) and garnish with parsley.
Tip: Sprinkle with grated Parmesan or red pepper flakes for extra flavor.

Assembly

Assembling Slow Cooker Italian Sausage and Peppers is all about creating a hearty, inviting dish. Here’s how to bring it together:

Choose Your Base: For sandwiches, slice crusty rolls (like hoagie or ciabatta) and lightly toast if desired. For pasta, cook al dente pasta (penne, rigatoni, or spaghetti) and drain.
Add the Sausage and Veggies: For sandwiches, place a whole or sliced sausage in the roll, then spoon peppers, onions, and sauce over the top. For pasta, toss the sausage, veggies, and sauce with the pasta or layer them on top.
Garnish: Sprinkle chopped fresh parsley over the dish for a vibrant, fresh finish.
Presentation Tips:
- For sandwiches, serve on a wooden board with a side of sauce for dipping.
- For pasta, use wide, shallow bowls to showcase the colorful peppers and sauce.
- Pair with a side of Caesar salad or garlic bread for a complete Italian meal.

Tip: For a cheesy twist, top sandwiches or pasta with shredded mozzarella or provolone and broil for 1–2 minutes until melted.

Storage and Make-Ahead Tips

Keep your Slow Cooker Italian Sausage and Peppers fresh and ready to enjoy with these tips:

Storing Leftovers:
- Store cooled sausage, peppers, onions, and sauce in an airtight container in the fridge for up to 4 days. Store rolls or pasta separately to prevent sogginess.
- Reheating: Reheat in the microwave (1–2 minutes, stirring halfway) or on the stovetop over low heat, adding a splash of water or broth to loosen the sauce. Reheat pasta or toast rolls separately.
Make-Ahead Tips:
- Veggies: Slice bell peppers, onion, and mince garlic up to 1 day in advance and store in the fridge.
- Assembly: Combine all ingredients in the slow cooker insert the night before, cover, and refrigerate. Start cooking in the morning.
- Pasta: Cook pasta up to 1 day ahead, toss with a little olive oil, and refrigerate. Reheat with hot water or sauce.
Freezing: Freeze cooked sausage, peppers, onions, and sauce (without rolls or pasta) in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating. Veggies may soften slightly after freezing.

Tip: The sauce’s flavors deepen over time, making leftovers perfect for quick meals!

Spicy Kick: Use spicy Italian sausage or add ½ tsp red pepper flakes for extra heat.
Veggie Boost: Include sliced mushrooms, zucchini, or spinach for added nutrition and texture.
Cheesy Upgrade: Stir in ½ cup shredded mozzarella or Parmesan at the end for a creamy, cheesy sauce.
Wine-Infused: Add ½ cup red or white wine for a richer, more complex sauce (reduce broth if adding).
