Swiss steak is a family favorite I’ve been enjoying since I was a little girl. It’s a comforting, filling meal, very easy to make and super delicious. It makes me think of Sunday dinners with my mom. It makes my mouth happy.

I’ve made it several times in the slow cooker for my family but my husband commented that this version in the thermal cooker was his favorite yet.

We decided the difference was that the vegetables don’t get nearly as mushy in the thermal cooker. They aren’t crisp by any means but they also aren’t pulverized.

I chose to make mashed potatoes this time for maximum comfort food. I got them PIPING hot and put them in the smaller nesting pot where they stayed nice and warm for the 6 ½ hours I had the meat cooking in the Saratoga Jacks.

However, this recipe is also really nice with rice or noodles.

I got home from an all-afternoon doctor’s appointment with my daughter, set the table, and when my husband walked in from work five minutes later, we ate. No stress.

Swiss Steak Quick Instructions

To make this meal, you dredge serving-sized pieces of steak in flour with a little salt and pepper. Then you brown them in oil in your thermal cooker pot, pour off excess fat and cover them with canned tomatoes and chopped vegetables. Boil the whole thing for at least three minutes, lid and seal it, and let it cook.
