🍳 Instructions
Step 1: Prep the Ingredients
Slice the bell peppers and onion, mince the garlic, and gather your seasonings. You can leave the sausage links whole, slice them into chunks, or crumble them depending on how you plan to serve the dish.
Step 2: Load the Slow Cooker
Add the sausage to the bottom of the slow cooker. Then layer in the sliced peppers, onions, garlic, diced tomatoes (with their juice), oregano, basil, salt, and pepper.
Step 3: Mix and Cook
Give everything a gentle stir to combine. Cover and cook:
- On low for 6–7 hours
- On high for 3–4 hours
You’ll know it’s ready when the sausage is fully cooked, the vegetables are tender, and the sauce is rich and bubbly.
Step 4: Serve It Up
Serve the sausage and peppers on crusty hoagie rolls, spooned over buttered noodles, or tossed with al dente pasta. Don’t forget to sprinkle with fresh parsley just before serving!

🔥 Pro Tips for Perfect Sausage and Peppers
- Brown the sausage first (optional): For extra depth, you can quickly sear the sausage in a skillet before adding it to the slow cooker. It’s optional, but adds flavor and better texture.
- Use hot Italian sausage for a spicy kick: If you like heat, go with spicy sausage and add a pinch of red pepper flakes.
- Avoid mushy veggies: If you like your peppers with a bit of bite, add them halfway through cooking.
- Make it saucier: Add an extra ½ cup of tomato sauce or crushed tomatoes if you prefer a more saucy consistency.
🍽️ Serving Suggestions
1. Classic Sandwich Style
Slice the sausage and load it into toasted hoagie rolls with a generous helping of peppers and sauce. Add provolone or mozzarella if you’re feeling cheesy!
2. Over Pasta
Serve over penne, rigatoni, or spaghetti for a filling and flavorful meal.
3. Low-Carb Option
Skip the bread and pasta—serve it in a bowl with cauliflower rice or roasted veggies.
4. Rustic Platter Meal
Pair with mashed potatoes or creamy polenta for a cozy, down-home dinner.
