These slow cooker sausage and peppers are one of my favorite don’t-feel-like-cooking meals. You don’t have to do much prep, and I love the combination of fresh ingredients and Italian flavors with the ease of the Crock Pot. Sausage, peppers, onions, and marinara sauce simmer together for a hands-off, healthy dinner that’s bursting with flavor. Grab your slow cooker and make these Crock Pot sausage and peppers with me!
Why You Need My Slow Cooker Sausage And Peppers

- Juicy, browned sausage – Many versions slice the sausage and skip the browning step, but I prefer to spend the time on quick sear instead of slicing — it locks in flavor! And slow cooking leaves the sausage more juicy than other cooking methods.
- Classic Italian flavors – The combination of marinara, sausage, peppers, and onions in the slow cooker is so comforting. (If you love this combo, I also use these flavors in my sausage stuffed zucchini and crustless pizza.)
- 7 simple ingredients – Plus salt and pepper. Doesn’t get much easier than this.
- Hands-off cooking – Like most of my slow cooker recipes, this one needs just 5-10 minutes of prep, and the Crock Pot does the rest. Perfect for busy days!


Ingredients & Substitutions
Here I explain the best ingredients for my Crock Pot sausage and peppers recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Sausages – I used pork Italian sausage links, but any kind works—sweet Italian, chicken, turkey, kielbasa, or bratwurst. You can even slice up extra for sausage and cabbage, or turn them into a sheet pan meal using a similar recipe I have in my Easy Keto Cookbook.
- Olive Oil – To brown the sausages. Any cooking oil is fine.
- Bell Peppers – Slice them into strips, like you would for fajitas. I used a mix of orange, yellow, and red, but green bell pepper works, too.
- Onion – You can use white, yellow, or red. Slice it into half moons, about the same width as the peppers.
- Garlic – Freshly minced garlic gives the best flavor, but you can use a tablespoon of jarred garlic for convenience.
- Italian Seasoning – I usually have my 5-minute Italian seasoning blend on hand, but store-bought is just fine. You can also just use dried basil or oregano alone. For a little heat, toss in some red pepper flakes!
- Marinara Sauce – I love this brand, but it’s a real treat if you’ve got time to make my homemade marinara sauce. You can also make these slow cooker sausage and peppers using crushed tomatoes or tomato sauce.
- Sea Salt & Black Pepper

How To Make Sausage And Peppers In The Crock Pot
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Brown the sausage. Sear both sides in a large skillet with a little olive oil. (If you prefer, you can air fry the sausages to brown them — just do it for half the time, so they don’t cook all the way through.)
- Slice and toss veggies. Place the bell peppers, onions, garlic, and Italian seasoning into your Crock Pot (I have this one), and toss together.


- Add the marinara and sausage. Pour the sauce over the veggies, then nestle the sausages on top.


- Cook sausage and peppers in the slow cooker. They are done when the sausages are cooked through, and the peppers and onions are soft.

My Recipe Tips
- Don’t fully cook the sausages during the browning step. They finish cooking in the slow cooker.
- Can you skip the browning step? Yes, you can. But I highly recommend doing it because it makes the sausages taste better and only takes a couple of minutes.
- Don’t slice the peppers and onions too thin. They will turn out mushy if you do. I aim for a bit wider than 1/4 inch.
- Prefer your veggies more crisp tender? Add them to the Crock Pot in the last hour of cooking instead of in the beginning.
- Drizzle the sauce over your slow cooked sausage and peppers. It’s very liquid, but adds extra flavor and moisture. So good!
- Prefer to use your oven? After browning the sausage, just layer everything in a baking dish and bake at 400 degrees F for 20-30 minutes, until the peppers are soft.
- Want to make it on the stovetop? I recommend my other sausage and peppers recipe that uses just the stove.
- Want to make it cheesy? Sprinkle shredded cheese (I recommend mozzarella) over the sausage and peppers in the slow cooker at the end. Cover with the lid to let it melt.

Storage & Meal Prep
- Store: Slow cooker sausage and peppers store well, though the veggies do get more mushy. Keep leftovers in an airtight container in the refrigerator for up to 3-4 days.
- Meal prep: Slice the vegetables and brown the sausages in advance. Then you can just toss everything in the slow cooker the day-of!
- Reheat: Use the microwave or a skillet on the stove. You can also reheat sausage and peppers in the Crock Pot on the Low or Warm setting.
- Freeze: This dish freezes well for up to 3 months. Thaw overnight in the fridge before reheating.
Serving Ideas
I’ve often served slow cooker sausage and peppers on their own, or with an Italian-inspired salad, like Caprese salad or romaine with Caesar dressing and parm.
If you want something more hearty, sausage and peppers taste amazing over a bowl of rice, cauliflower rice, or roasted potatoes. You can also make sandwiches with them — just stuff the sausage into a roll that fits your lifestyle, and add the peppers and onions.

0Had for dinner tonight. LOVED THEM. Great after working outside all day long❤️
Carisa Diaz
0We don't eat sausage. Is there another meat you'd recommend making this with?
Maya | Wholesome Yum
0Hi Carisa, Yes, you can use chicken or turkey sausage instead.
Marsha N
0If you are using fully cooked sausages, do the sausages require the same amount of cooking time in the crock pot as uncooked sausages? I realize the peppers & onions require the time stated for cooking. Thanks.
Maya | Wholesome Yum
0Hi Marsha, No, you wouldn’t have to cook as long if your sausage is already fully cooked. I’ve only made this recipe with raw sausage so I don’t have an exact time for you, but you can check on them and stop cooking once the peppers and onions are done to your liking. They will be just fine cooked for less time.
Pamela
0How many does it serve?
Wholesome Yum D
0Hi Pamela, This recipe serves 6.
Cathy
0Can you cut up the sausage after browning them so they aren’t whole in the crockpot?
Maya | Wholesome Yum
0Hi Cathy, You can, but I’m guessing the cook time might be different. I haven’t tried that to confirm. We just cut the sausages after cooking.
Maria
