I am often asked what kind of red wine to use for this recipe. As long as it’s a dry red wine you should be good to go. A Cabernet Sauvignon, Pinot Noir, or Merlot will do just fine.

Heck, I’ve even used a nice Malbec with great success. Just use what you have on hand. Remember, if you wouldn’t drink it, don’t cook with it.

Alcohol Warning

Please take into consideration that some of the alcohol in this recipe may not completely burn off and the remains could be of significant concern to recovering alcoholics, parents, and others who have ethical or religious reasons for avoiding alcohol.

Giardiniera

Whenever I can I like to use a Sweet Brown Onion for this recipe. If you don’t have any you can easily substitute for a regular Yellow Onion.

If you don’t have any Fresh Thyme on hand you either omit it completely or substitute it for some regular or Italian Oregano.

I typically use a chuck roast when making this recipe but you can use other cuts of beef if needed. A Top Round Roast while a little pricier (at least in my area), would make a good substitute when making this slow cooker sandwich recipe.
