Tools used in the making of this Beef Brisket with Caramelized Onions:
Cast Iron Skillet: This is my most used pan in my kitchen, heavy, keeps heat well and gives the BEST sear ever.

  1. I have never slow cooked a beef brisket before, and this recipe made me feel like a pro! It was easy to prepare (minus the onion crying lol), very low maintenance while cooking, and turned out very delicious! I brought it to a friend’s B-Day party where everyone brought a dish, and this ended up being the party favorite and was gone before I knew it! Got lots of props from it too. Would definitely recommend this, and now I have a go-to dish to bring to get-togethers. Thanks a lot for this gem!

  2. Best easiest recipe! Probably the most tender piece of meat I’ve ever made. A foolproof keeper. I had some homemade chicken broth on hand that I substituted for beef broth and I marinated the brisket in a mix of spices and soy sauce for about 6 hours. I used a 2 lb brisket and cooked it in a cast iron skillet for roughly 3 hours. It was a giant hit!
