What goes well with Kielbasa?

If you would like to serve this low carb Kielbasa with Peppers & Onions in Spaghetti Sauce with a side dish for a bigger meal I would suggest:

Can This Kielbasa Recipe Be Made Ahead?

Sure it can! Simply cook it as this healthy Kielbasa recipe shows. If you will be eating it within a couple hours, it can remain on the stove top, covered.

But if you need to cook it the day before or even longer, it will need to be kept in the refrigerator. It will keep safely in the frig for 3-4 days.

Just pour it into a large bowl with a lid and store.

Can You Freeze Kielbasa with Pepper & Onions in Spaghetti Sauce?

Of course! I do it all the time. My husband travels a lot and I prepare his meals to take with him on the road.

To freeze, line a freezer safe container with freezer paper (this is only to keep the bowl from getting so nasty). Put a single serve size in the bowl, pull the freezer paper over the top, label and place on container lid, place in freezer.

You can leave it in the container and it will keep for 6-7 months. I go a step further, since his travel refrigerator has limited space.

Once it has been in the freezer for a couple of days. Take it out, and place into a Ziploc bag & it will freeze for about 1 year. But I use this Foodsaver machine and it will freeze safely for 2-3 years because all the air is vacuumed out.

How to Reheat Kielbasa with Peppers & Onions Recipe

If I’ve left this quick meal on the stove top for just couple hours, we normally pop it in the microwave in single serve sizes and be done with it. Be sure to use a microwave safe dish.

But, if it has been in the frig over night, I don’t like to put it in the microwave. I get my iron skillet out, heat the skillet on the stove top and pour this homemade Kielbasa recipe in it. Heat for about 15 minutes or until it begins to bubble. And then serve.

Doesn’t this quick and easy Kielbasa recipe with Peppers and Onions sound delicious?

It’s perfect as a quick meal recipe that can be served instantly or made ahead to serve later.
