Crock Pot Sausage and Peppers has always been one of those comfort dishes that transforms an ordinary day into something warm and satisfying.
The moment the slow cooker lid lifts and that rich, tomato-soaked aroma fills the kitchen, it feels like a meal that has been simmering in anticipation all day.
When I made this Crock Pot Sausage and Peppers, the combination of sweet Italian sausage, tender peppers, and savory marinara created a nostalgic smell that reminded me of family gatherings and easy weeknight dinners.
What I love most is that Crock Pot Sausage and Peppers requires minimal effort but delivers maximum flavor—the kind that feels like it cooked itself while you went about your day.
As the sausages slowly softened and absorbed all those flavors, I knew this Crock Pot Sausage and Peppers recipe would become one of those dependable dishes I’d keep coming back to, especially when I want something hearty yet incredibly easy.
Why Crock Pot Sausage and Peppers Is the Ideal Recipe
When I prepare Crock Pot Sausage and Peppers, I always appreciate how perfectly it fits into busy days without sacrificing taste.
The slow cooker does most of the work. Searing the sausage beforehand gives the Crock Pot Sausage and Peppers a deep, caramelized flavor, and the long slow cook blends every ingredient seamlessly.
The peppers soften into silky ribbons, the onions melt into the sauce, and the sausage becomes unbelievably tender.
Key Ingredients in Crock Pot Sausage and Peppers Recipe
Here are the standout ingredients that make this Crock Pot Sausage and Peppers truly shine:
Sweet Italian sausage (3½–4 lbs): I like using Johnsonville because the flavor is consistently rich and the sausages hold up beautifully during slow cooking.
Bell peppers (3 small or 2 large): Any color works, and each brings a different sweetness. Sliced thin, they cook down into the sauce perfectly.
Yellow onion: Thinly sliced so it softens quickly and blends into the marinara.
Salt and pepper: Simple seasonings that balance the richness of the sausage.
Garlic (4 cloves): Freshly minced garlic deepens the flavor of the sauce.
Red chili pepper flakes: Optional, but they add a subtle heat that elevates the whole dish.
High-quality marinara sauce (2 jars): The sauce acts as the foundation of the entire recipe, so using a good brand makes a noticeable difference.
Sub rolls, provolone, mozzarella, or pasta for serving: These serving options turn the dish into a meal that suits everyone at the table.

Description
Crock Pot Sausage and Peppers Recipe combines tender sweet Italian sausage, sliced bell peppers, onions, garlic, and rich marinara sauce slow-cooked to perfection for an easy, flavorful, and satisfying family-style meal.
Ingredients
- 3–1/2 – 4 lbs sweet Italian sausage links, cut in half, Johnsonville recommended
- 3 small or 2 large bell peppers, any color, seeded then thinly sliced
- 1 large yellow onion, cut in half then thinly sliced
- salt and pepper
- 4 cloves garlic, pressed or minced
- pinch red chili pepper flakes, optional
- 2, 24-26oz jars high-quality spaghetti or marinara sauce, see notes
For serving:
- Sub or hoagie rolls
- Thinly sliced provolone or mozzarella cheese
- Cooked pasta
Instructions
Line a prep cup with foil then set aside.
Heat a large, 12”+ skillet with high sides over medium-high heat. Once hot, spray with nonstick spray then add as many sausage halves as will fit in the bottom. Sear the sausages until golden brown on all four sides (sausages do not need to be fully cooked through) then transfer to a 6-quart crock pot. Pour the fat into the foil-lined prep cup then repeat with the remaining sausages, turning the heat down slightly if necessary to prevent burning.
After the last batch of sausages, pour out all but ~1 Tablespoon fat from the skillet then turn the heat up slightly. Add the peppers and onions to the skillet, season with salt and pepper, then saute until the vegetables begin to soften, 3-5 minutes. Add the garlic and red chili pepper flakes, if using, then saute for one more minute. Scrape the vegetables into the crock pot with the sausages.
Pour the spaghetti/marinara sauce into the crock pot. Add a couple Tablespoons of water into each jar then shake to loosen up any sauce on the sides and pour into the crock pot. Stir to combine all the ingredients then place a lid on top and cook on LOW for 5-6 hours or until the sausages are extremely tender. Use a spoon to scoop off the fat that rises to the top of the crock pot.
Butter and toast rolls or buns under the broiler then place the cooked sausage and peppers plus a little sauce on top. Add a slice or two of cheese then broil until melted. Alternatively you can serve the sausage, peppers and sauce over cooked pasta.

How to Make Crock Pot Sausage and Peppers Recipe Step-by-Step
-Line a prep cup with foil and set it aside. This makes it easier to collect and discard excess fat later.
-Heat a large skillet over medium-high heat. Spray with nonstick spray once it’s hot, then add as many sausage halves as you can fit. Sear each piece until golden on all sides. They don’t need to be fully cooked—just browned for flavor. Transfer the browned sausage to the crock pot. Pour the fat from the skillet into the foil-lined cup.
-Continue browning the remaining sausages in batches. If the skillet starts to darken too quickly, turn the heat down slightly. Transfer each batch to the crock pot.
-When the last batch is done, pour off all but about one tablespoon of fat from the skillet. Increase the heat slightly and add the sliced peppers and onions. Season with salt and pepper. Sauté for 3–5 minutes until the vegetables begin to soften.
-Add the minced garlic and the optional chili flakes. Cook for about one more minute until fragrant. Scrape everything into the crock pot, making sure no flavorful bits remain behind.
-Pour in both jars of marinara sauce. Add a couple tablespoons of water to each empty jar, shake them well to loosen the remaining sauce, and pour that into the crock pot too. Stir everything so the sausages are nestled well into the sauce and vegetables.
-Cover and cook on LOW for 5–6 hours, or until the sausages are extremely tender and the sauce has deepened in flavor. Skim off any fat that rises to the surface.
-Toast your rolls under the broiler if serving as sandwiches. Add sausage, peppers, and a spoonful of sauce. Top with provolone or mozzarella and broil again until melted. Alternatively, spoon the mixture over warm cooked pasta for a comforting bowl meal.
