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 you freeze this if you make it ahead?
Abeer Rizvi
Yes, you can.
Angelica
This might be a stupid question but is the nutrition facts per serving? Or for the whole crockpot meal?
Abeer Rizvi
It's per serving.
Jeanne
This is the best dinner Iโve made in a long time! Thank you for putting it out there. My husband said he gives it 100 thumbs up!
Abeer Rizvi
Awww! That makes my heart so happy!
Marie
I literally just turned my crockpot off and scooped some out. The flavor is delicious, however I cooked mine on low for 6 hours and 15 minutes and I feel like that was way too long. Again I will say the flavor of everything is so tasty, but it is also much too soft for my liking. ย Iโll make it again on low for 3-4 hours.
Emily
Iโm about to make this for the first time and canโt wait. But what side dish would you do or have done with this?
Abeer Rizvi
Hi Emiliy! If you scroll up, I have included a whole section on sides you can serve with this meal. I have that section, variations and tips in all of my posts.

I browned the sausages before adding them to the crockpot. I like the color it added. The sausages were not done. I also used a good quality marinara sauce. I also spread garlic butter on the rolls and toasted them. The hoagies were great!!
Sunita
Hello Iโve not made it yet but have ย prepared everything for tomorrow. ย I have decided to brown the sausage and deglaze the frying pan with just a little water as I didnโt want to loose the juices. ย Canโt wait to try it ...yummm
Kate A
Thank you! This was so easy and it came out excellent.
Elisha
2 cups of marinara doesnโt seem like enough. Iโm following instructions to the t but afraid for it to burn in the crock pot.
Abeer Rizvi
Trust me... it's enough. I have made it multiple times and so have others and it works perfectly.
Allison
Do you use flavored marinara or plain?
Abeer Rizvi
I used plain but you can use flavored too.
Mariet
This is delicious and sooo easy. Made a smaller version for the 2 of us, 3 Italian sausages, 2 big green peppers and a big cup of pasta sauce, ready in 3 hours, definitely a keeper.ย
