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.

This recipe is easy and delicious! I browned the sausage in a pan first then put it in the crockpot for extra flavor and texture. This recipe will be in my regular rotation.
Nancy Young
I made this exactly as directed except I did add a couple left over tablespoons of tomato paste. Cooked it low in my crockpot. What we loved best was the texture of the meat. Needless to say, I had no leftovers and this recipe is going in my rotation for sure!
Samantha
This recipe is a winner! My whole family loves it, and Itโs my favorite go-to meal for a busy weekday. We serve it with quinoa and it is yummy, warm, filling, and makes great leftovers (if you can contain yourself).

Hi. Sounds delicious. Would homemade salsa work instead of marinara?
Abeer Rizvi
I don't see why not. It would just be a different flavor and nothing wrong with that.
Daphne
Fixed this today with some bowtie pasta and it was amazing!!

My husbands family is Italian and naturally are very picky when it comes to good Italian food. I received SO many compliments on it being the best they have had. This was a meal I brought because we had a death in the family so it was extra special for my sister in law to have her favorite dish, and I left her the leftovers. Thank you for this delicious recipe.

Trying this now....however, I scrolled down a little too late to see that the sausages should be the precooked kind. Just fished my raw sausages out to precook them. Maybe it would be helpful to other to mention up front in the ingredients list that the "precooked" links are preferred. Looking forward to the finished product....Thanks!
Tina
I was confused myself but I donโt think the recipe uses pre-cooked sausages because I have never seen pre-cooked Italian sausages especially not cooking in the slow cooker for that length of time. Real Sausage and Peppers is always with uncooked sausages.ย

Why do directions say cook till sausage is cooked thru if sausage is precooked? Haven't made it yet. Asking i n advance.
Abeer Rizvi
I think I didn't word it right. If someone is using uncooked sausages, they need to lightly brown it first on stovetop but it won't be completely cooked through and allow the remainder of the cooking to happen in the crockpot.
That being said, I highly recommend using precooked sausages for convenience.
