Deviled Swiss Steak sounds like something Beaver’s mom would’ve made in heels and a frilly apron. But this slow-cooked version, filled with chuck steak, carrots, onions, tomatoes, and a touch of dry mustard, is just as comforting today as it was at Sunday dinner when I was growing up.
My mom didn’t wear heels, but she made this regularly—long before slow cookers were a thing. Now, with a Crockpot and a few pantry staples, you can let the magic happen while you’re off doing something else.

“I just finished making this in the crockpot and wow! it is good! And if you, like me, find out your onion has gone bad, onion powder worked just fine. if it’s this good right now, I can’t wait to taste it tomorrow! (Dry mustard is a miracle ingredient, just saying. Deviled eggs, this recipe. and it goes on. Yum!)” — CEE O.
What Do “Swiss” and “Deviled” Mean?
“Swiss” refers to pounding the meat to tenderize it—common with round steak. My mom used a mallet, but with slow cooking, the meat becomes fall-apart tender either way.
“Deviled” is an old-school culinary term for adding spicy or zesty seasoning. Here, it comes from the dry mustard—more flavor than fire. It’s the same ingredient that makes deviled eggs so good.

Frequently Asked Questions
Can I make this ahead of time?
Yes. It keeps well for 2–3 days in the fridge. Reheat in the microwave for best flavor and moisture.
Can I make this in the oven instead of a slow cooker?
Absolutely. Cover tightly and bake at 325˚F (163˚C) for 2½ to 3 hours, depending on steak thickness.
📌 Tip: Check occasionally and add water if it’s getting dry—especially if your pan doesn’t seal well.
What cut of meat works best?
Chuck steak, chuck roast, or round steak all work. Chuck eye or stew meat are good alternatives if you’re using what you have.
What should I serve with it?
Mashed potatoes, rice, or polenta are classic. For low-carb, try mashed cauliflower or cauliflower rice. My current favorite? Corn polenta—no tomatoes on top.
What can I do with leftovers?
Chop the beef and use it in:
– Weeknight Shepherd’s Pie
– Vegetable Beef Soup
– Homemade pot pie (even if you’re winging it)
