Ingredients

Here’s what I use for this recipe and you can always make substitutions if you prefer.

• Italian sausage: Sliced into 1-inch rounds to create hearty pieces with browned edges.
• bell pepper: Cut into strips using red green and yellow peppers for color and sweetness.
• yellow onion: Sliced into strips to add savory flavor as it softens.
• russet potato: Cut into 1-inch chunks that hold their shape during slow cooking.
• crushed tomatoes: Added as the tomato base that coats the sausage and vegetables.
• olive oil: Helps carry seasoning and adds richness to the sauce.
• Italian seasoning: Provides dried herb flavor throughout the dish.
• garlic powder: Adds savory garlic notes without extra moisture.
• paprika: Adds warmth and color to the sauce.
• salt: Balances the flavors of sausage and vegetables.
• black pepper: Adds mild spice and depth.

Tools You’ll Need

• 6-quart slow cooker: A 6-quart slow cooker gives the sausage and vegetables room to cook evenly, while a smaller cooker can crowd ingredients and leave potatoes unevenly tender.
• Sharp chef knife: A sharp chef knife creates clean pepper strips and sausage slices, while a dull blade can crush vegetables and create uneven cooking pieces.

Instructions

Step 1: Slice the vegetables and sausage

Slice 1 pound Italian sausage into 1-inch rounds and cut 3 bell peppers and 1 yellow onion into strips. Work at room temperature around 70°F for 10 minutes. Use a sharp knife with a rocking motion and keep the pieces uneven for a homemade look.

Then place the sliced ingredients into the slow cooker with 1-inch russet potato chunks. You’ll see bright peppers, pale potatoes and sausage pieces layered naturally. Miss this prep window and uneven sizes can cook at different speeds.

Cut evenly at room temperature, consistent pieces cook through together.

Tip: Choose firm bell peppers with smooth skin because softer peppers release extra water during the 6-hour cook.

Step 2: Layer the ingredients with sauce and seasoning

Add 14 ounces crushed tomatoes, 2 tablespoons olive oil, 1 tablespoon Italian seasoning, 1 teaspoon garlic powder, 1 teaspoon paprika, 1 teaspoon salt and 1/2 teaspoon black pepper. Combine everything at 70°F for 5 minutes by folding gently with a large spoon.

The sauce should coat the sausage and vegetables evenly before cooking. You’ll notice the tomatoes become glossy around the peppers and potatoes.

Skip this mixing step and the seasoning won’t spread evenly through the dish. Fold ingredients gently for 5 minutes, even coating builds balanced flavor.

Tip: Keep the potato pieces near the bottom because they need direct contact with the sauce to soften properly.

Step 3: Slow cook until tender and glossy

Cook the mixture at 200°F to 210°F on low heat for 6 to 7 hours. Stir once at the halfway point around hour 3 using a slow folding motion to move the vegetables without breaking them.

You’ll see the peppers soften, the sausage edges deepen to golden brown and the sauce thicken around the potatoes. (I tried cooking only 4 hours first.

The potatoes stayed firm, so the longer window gave the best texture. ) Cook slowly for 6 hours, gentle heat breaks down fibers without drying sausage.

Tip: Avoid lifting the lid during the first 3 hours because the slow cooker loses heat and extends the cooking time.

Step 4: Finish and serve the sausage dinner

Rest the finished Crockpot Sausage and Peppers at 165°F internal temperature for 10 minutes before serving. Use a spoon to gently portion the sausage, peppers and potatoes while keeping the sauce around each serving.

The final dish shows glossy sauce, tender potato centers and browned sausage surfaces. You’ll smell the Italian seasoning and see the peppers holding their shape.

Miss the resting window and the sauce won’t settle into the vegetables as well. Rest 10 minutes before serving, it helps juices redistribute evenly.

Tip: Add fresh parsley after serving for color without changing the slow cooked flavor.

Pro Tips

• Brown the Italian sausage slices before slow cooking at medium-high heat for 3 to 4 minutes per side if you want deeper color and extra savory flavor from the edges.
• Choose firm bell peppers with bright skin and no soft spots because they hold their shape better during the 6 to 7 hour slow cooking window.
• Cut russet potato chunks close to 1 inch so they finish at the same time as the sausage and peppers instead of turning mushy.
• Add the crushed tomatoes evenly over the ingredients before cooking because this prevents dry spots during the first 2 hours.
• Finish each serving with 1 tablespoon chopped fresh parsley after cooking to add a fresh contrast against the rich tomato sauce.
• For a thicker sauce, remove the lid for the final 15 minutes on high heat and let excess moisture escape until the sauce lightly coats the sausage.

• Add 1/2 teaspoon crushed red pepper flakes and 1 cup sliced mushrooms for a spicy mushroom version with deeper earthy flavor.
• Swap the russet potatoes for 1 pound sweet potatoes to create a slightly sweeter fall crockpot recipes variation.
• Add 1 cup sliced green olives during the final 30 minutes for a briny Italian-inspired twist that changes the flavor without changing the cooking method.
• Serve the sausage mixture over 3 cups cooked penne for a pasta-based dinner that turns this into a heartier meal.

Storage Instructions

Store leftover Crockpot Sausage and Peppers in airtight glass containers and keep them in the refrigerator at 40°F or below for up to 4 days. You can also freeze portions for up to 3 months. Just let them cool completely, then place them in freezer-safe containers and wrap them tightly.

Thaw overnight in the fridge before reheating. Warm individual portions in the microwave at 165°F for about 2 to 3 minutes, or heat gently on the stovetop until steaming. If the sauce gets too thick after chilling, stir in 2 tablespoons of water or broth to loosen it up.

Don’t eat leftovers if they have a strange smell, mold or a slimy texture.
