Whats sides to serve with Italian sausage and peppers recipe?
This hearty dish can be enjoyed on its own but you can also enjoy it with a salad. A simple green salad without an overpowering dressing is best. Coleslaw also pairs very well.
You can also serve it alongside bread like breadsticks, dinner rolls, crusty artisan bread, pita bread, garlic bread or hot dog buns. Use it as a filling in sandwiches, tortilla rolls and wraps.
Enjoy it with vegetables like mashed potatoes or mashed sweet potatoes or mashed cauliflower.
You can even use it in stuffed peppers or stuffed potatoes.
My family really likes it with pasta. Any type will work fine. A healthier alternatives to that would zoodles (zucchini noddles) and spaghetti squash.
Try it with soup. It tastes delicious with creamy soups.
Some other filling sides are quinoa and rice.
Variations for sausage peppers and onions
Sausage and peppers pasta - Mix in boiled pasta at the end.
Sausage peppers and potatoes - Potatoes pair well with just about every dish. If you want to add in some potatoes, simply slice up about a pound of waxy potatoes and add them in with the rest of the ingredients.
Add chicken - Simply slice up 1 pound boneless chicken breast cubes and add it along with the other ingredients.
Make it spicy - Add some jalapenos or other hotter peppers or red chili flakes for a nice spicy kick. You can also drizzle the finished dish with hot sauce.
Add more veggies - Add other vegetables you like such as eggplant, squash, zucchini, potatoes, mushrooms etc.
Mix up the seasoning - Instead of Italian seasoning, you could use Mexican or even Cajun seasoning for a different flavor profile.

Storage
Refrigerate- In an airtight container in the fridge for up to 3 days.
Freeze - In a sealed container for up to 1 month.
Reheat - In the microwave or stovetop until heated through.
Tips and Techniques
Store-bought vs. Homemade Italian Seasoning - Either can be used. It does not affect the overall flavor whichever one you use.
Mix up the peppers - I like using a combination of colored peppers, but you can use any pepper of your choice.
Use fresh peppers - Avoid using frozen peppers or veggies as they release a lot water when they go through the cooking process. Plus, they lack the flavor needed for this dish.
How to thicken sauce/ gravy? The best way to thicken this dish is to let it cook longer. Sometimes, letting it cool will also thicken it. If you want it very thick, just cook off excess liquid on stovetop.
How to thin out the sauce/ gravy? Simply add some extra broth or water until the desired consistency has been reached.
Cut the peppers and onions thick - If you cut the onions and peppers too thin, they will simply dissolve into the sauce and not be a very prominent part of the dish like they should be.
Adjust quantity of Italian seasoning- Use more or less, based on your preference.

Can I incorporate chicken thighs on the bone with the sausage and green peppers?
Abeer Rizvi
I haven't tried that to know how that would affect the recipe.
sabrina martin
does the sausage need to be cooked before hand?
Abeer Rizvi
I used cooked sausages.
Robert Leeds
I made these last week, but marinara is a little too thin for me. I am trying a thick Prego spaghetti sauce the next time.
Marlie Jesso
This dish I made tonight for date night with my fiancรฉ. And it was a huge hit, had some garlic bread on the side really complimented the dish, only thing I would of done differently was fry the sausages instead of adding it to the crockpot. But other then that absolutely delicious dish will totally make again.
Audrey
Just had polish sausage on hand would that working okay with this recipe..???
Abeer Rizvi
That should work fine.
Pamela
I made this ย for the first time last night and it ย smelled so delicious we had a hard time keeping out of it. Iโm one to add a little bit of this or that to my cooking but didnโt add a thing to this. Cooked on low for 5 hours and turned off so the peppers and onion didnโt get mushy! Thank you so much ย for sharing this wonderful recipe.ย
Abeer Rizvi
Yay for no mushy sausages. Can't stand that myself either...lol.
Pamela
Mushy peppers and onions not sausage.ย
Gracie
This might be a dumb question, but the sausages I bought are Beelerโs precooked kind. Thatโs what this recipe calls for right? Not raw sausages?
Abeer Rizvi
Yes, use cooked sausages. And not a dumb question at all.
Danielle
I have raw sausages for this. I thought they would cook in the slow cooker. Did I buy the wrong kind? Thanks!
Abeer Rizvi
They should be the cooked sausages.
Stacy P
You can use raw italian sausage I do it all the time on low 6-8 hours or high 3-4...You get the same result.
Maddy
Yes, I use raw Italian sausages all the time and they come out fine.
Janice Parker
Thanks for asking Gracie. I had the same question.
Joani
Do you think smoked sausage would work too?
Abeer Rizvi
Yes. It would add a lovely flavor.
