A dry white or red wine works best.

It all comes down to personal preferences.

  • Step one: You will want to slice your onions and then add your butter and olive oil to the instant pot.
  • And turn it on simmer, once the butter has melted you will add in the onions, salt and pepper and 1 package of Knorrs onion soup mix (my secret ingredient)

Yes and it even tastes better the next day. So go ahead and make a BIG old pot and save some for another day! Just make sure that you do not freeze it with croutons or the cheese.

Place those on it the day of serving it!

Notes: Keep in mind, as with all my recipes.

If you want to make more or less of this soup, simple adjust the serving size in the ingredients sectionabove and the servings will automatically adjust for you.

And save yourself time and hassle, and let your food processor chop up your beets and cabbage up.

Also it gives a great consistency to the soup.
