Ingredients You’ll Need
Italian sausage links (2 packages, 19-ounce each): These serve as the star of the dish, providing rich, bold flavors that are essential for a classic taste. You can use sweet or spicy sausage based on your preference. Turkey or chicken sausage works well for a lighter version, too.
Olive oil (1 tablespoon): Used for searing the sausage links, this oil adds depth to the dish through its rich flavor. If you prefer, you can substitute it with grapeseed oil or avocado oil.
Bell peppers (6, mixed colors, sliced into strips): A mix of red, green, yellow, and orange peppers creates a vibrant dish that not only looks appealing but also contributes various sweetness levels. Feel free to swap in other colors or varieties for a unique twist.
Onions (2, sliced into strips): Onions bring a flavorful aromatic base that complements the sweetness of the bell peppers beautifully. Vidalia or sweet onions can add a lovely, mild sweetness, whereas yellow onions yield a more robust flavor.
Garlic (4 cloves, minced): Garlic enhances the dish with its savory essence, elevating all the flavors. If you’re short on fresh garlic, garlic powder can work in a pinch–use about half a teaspoon.
Marinara sauce (1 1/2 cups): This adds moisture and a medley of flavors that bind the ingredients together. Opt for your favorite jarred marinara or make your own for a fresher taste.
Italian seasoning (1 tablespoon): A blend of herbs including oregano, basil, and thyme, this seasoning rounds out the flavor profile. You can also create your own blend if you wish to personalize it.
Salt and pepper (to taste): Basic seasonings that allow you to elevate the dish further by enhancing the other flavors.
How to Make Slow Cooker Sausage and Peppers

Preheat and Sear
Start by heating a large skillet over medium-high heat and add the tablespoon of olive oil. Once the oil is shimmering, carefully place the Italian sausage links in the skillet. Sear each side for about 2-3 minutes or until they’re beautifully browned and crisped, giving them that charred flavor that contrasts wonderfully with the tender vegetables later on. This step is crucial as it caramelizes flavorful compounds, enhancing the taste of your dish.
Combine Peppers and Onions
While the sausages are searing, go ahead and prepare your veggies! In your slow cooker, add the sliced bell peppers, onions, and minced garlic. The combination of these veggies adds both texture and sweetness to your dish. Pour in the marinara sauce, followed by the Italian seasoning, salt, and pepper. Give everything a gentle stir to blend those gorgeous flavors. It’s a lively and colorful mixture that seems to come to life in the slow cooker.
Arrange Sausages
Next, once your sausage links are perfectly seared, nestle them on top of the pepper and onion mix in the slow cooker. Don’t worry about fully cooking them; the slow cooking process will finish the job, allowing their flavors to meld beautifully with the marinara sauce and vegetables. Just imagine the succulent juices from the sausages mingling with the sauce as they cook away.
Set and Slow Cook
Cover the slow cooker and set it to cook on low for about 5 hours or on high for about 3 hours. During this time, the peppers and onions will become tender, while the sausages are fully cooked through. You’ll want to check on it occasionally and savor the aromatic scents wafting through your home—the anticipation is half the fun!
Stir and Serve
When the cooking time is finished, remove the lid and stir everything gently to combine the sausage and peppers with the marinara sauce. At this point, you might consider warming some hot dog buns in the oven, as they are perfect for serving alongside this dish. The warmth of the buns paired with the hearty sausage and peppers is sure to be a crowd favorite.
Tips for Success
Don’t Skip the Searing: Searing the sausages before adding them to the slow cooker creates a rich flavor that enhances the overall dish, so don’t rush this step!
Use a Variety of Peppers: Mixing colors adds visual appeal and varying flavors, making each bite a delight.
Monitor the Cooking Time: If using tougher sausage or different models of slow cookers, keep an eye on the dish toward the end of the cooking time to ensure everything is perfectly tender without overcooking.
Experiment with Marinara: Try different marinara sauces or even flavored versions. Homemade marinara can be an excellent option if you want to control the ingredients.
Let It Rest: Allow your dish to sit for a few minutes after cooking before serving. This allows the flavors to settle and infuse together.
Serve It With
To make your meal even more delightful, consider pairing it with a crusty baguette for dipping, a side salad drizzled with vinaigrette, or a glass of hearty red wine. You can even serve the sausage and peppers on top of creamy polenta or rice for a comforting bowl of goodness. For a fun twist, place everything inside warm hot dog buns for a satisfying sausage sandwich that’s perfect for casual dining.
How To Store & Reheat Leftovers
If you happen to have leftovers (though I doubt they’ll last long), allow them to cool completely before transferring to an airtight container. At room temperature, it’s best to consume leftovers within 2 hours. Refrigerate for up to 4 days. For longer storage, you can freeze the dish for up to 3 months. Just make sure to separate it into smaller portions for more manageable reheating. To reheat, simply pop it in the microwave for 2-3 minutes or warm it in a skillet until heated through. The wonderful flavors will still be intact; just remember that the texture of the peppers may soften further with each reheating.
Tips & Variations
Spice It Up: For those who enjoy a bit more heat, consider adding red pepper flakes to the marinara sauce or using spicy sausage links.
Add More Veggies: Feel free to throw in other vegetables like zucchini or mushrooms to create an even heartier dish.
Swap the Main: For those wishing to go meatless, replace the Italian sausage with eggplant or even tofu for a plant-based alternative.
Seasonal Variations: During the fall, consider adding butternut squash or sweet potatoes for a seasonal spin that adds sweetness and texture.
Cheesy Option: Once fully cooked, sprinkle some shredded mozzarella cheese on top, cover, and let it melt for a cheesy twist.
