Ingredient Notes

Here’s what you’ll need to make this cozy, one-pot steak and potatoes dinner.

Sirloin steak: Slow cooking makes it fall-apart tender, bringing bold, beefy flavor to every bite.
Baby Honey Gold potatoes: These little potatoes soak up the juices and turn creamy, like soft bites of mashed potato in every forkful.
Worcestershire sauce: Just a splash adds tang and depth, tying everything together with a savory kick.
Minced garlic: Builds a cozy, roasted flavor that blends right into the steak and buttery sauce.
Dried onion soup mix: Packs big flavor in a small packet, seasoning the whole dish with rich onion taste.
Beef broth: Soaks into everything, adding savory depth and keeping the meat and potatoes perfectly tender.
Butter: Melts down into the broth, giving the dish a rich, homey, comforting finish.

Julie’s Tips From The Kitchen

Optional: If you want a rich, caramelized crust on the meat, sear it on all sides in a skillet with a tablespoon of butter before adding it to the slow cooker.

To make gravy from the Crock Pot juices, melt two tablespoons of butter in a saucepan over medium heat. Stir in two tablespoons of all-purpose flour—it’ll look lumpy at first. Slowly whisk in the cooking liquid and let it simmer until smooth and thickened.

I purchased the steak bites in smaller chunks to save time, instead of cutting them at home. Most meat counters will do this for you at no extra charge.

Add a dipping sauce on the side. Garlic aioli, horseradish cream sauce, steak sauce, or even chimichurri go great with this steak.

Storage, Freezing, And Reheating Instructions

Store any leftovers in an airtight container and keep them in the refrigerator. To reheat, place the steak and potatoes in a covered skillet or saucepan with a splash of broth or water, and warm over medium-low heat until heated through. You can also microwave it in 1-minute intervals, stirring in between, until hot.

You can freeze the steak and potatoes for up to three months. Allow the dinner to cool and then place it in an airtight container or freezer bag and freeze. When ready to use, thaw it in the refrigerator overnight.

  I haven’t tried it, but you definitely can. It might not come out as tender, but it will still be delish!

Looking at the picture, it looks awful greasy. What happens if you leave out the butter or just decrease it.

  Hi BJ,
  
  You can either decrease it or leave the butter out. It will still taste great!

This is a good recipe except seasoning, I added salt and pepper to the meat, and cut up some bell peppers and onions on the meat before I added the garlic, soup mix and Worcestershire sauce, I really like the potatoes, I mashed them up added milk and sour cream, then made a gravy from the sauce. It is very bland without seasonings.
