Tender round steak with mushrooms and onions in a slow-cooker
If your idea of a perfect steak is a tender cut of juicy, tasty, tender beef, then this slow-cooker recipe will give you perfection. The round steak cooks beautifully; the meat is flavorful and tender. The mushrooms and onions are moist and tasty, and the two infuse the beef perfectly. Typically I prefer steak that is medium rare because of its tenderness and taste, but using a Crock-Pot, you get tender and tasty in a medium-done steak.
Interestingly, I’m not sure of the exact source of the original recipe, but I remember it included canned or jarred mushrooms and canned beef gravy as the liquid. I replaced jarred mushrooms with fresh mushrooms, and beef gravy with beef stock (mixed with cornstarch to make it thicker). The first time I made it, I was a little worried it might not turn out, because I was using fresh ingredients instead of prepared, and because my memory of round steak from childhood dinners was not very positive (sorry Mom).
As I drove home from work, I cursed my Crock-Pot folly and considered other dinner options, worrying that the meat might be tough, the mushrooms disintegrated, or the stock just a runny mess. But it was delicious. I’ve made it a few times since and the meat is always tender and tasty, the mushrooms and onions provide a nice flavorful accompaniment, and the stock forms a light gravy.
I enjoy eliminating prepared foods not only because I am eliminating unnecessary chemicals, but it tastes better too, and is usually much more economical.
- Round Steak - 2 lbs., and about 1 inch thick, cut into “steak” sized pieces
- Mushrooms - 16 oz., sliced, fresh
- Onion - 2 medium, sliced
- Garlic - 3 cloves, minced
- Beef Stock - 2 cups
- Corn Starch - 3 Tblsp.
- Red Wine - 1/2 cup (optional, gives a richer flavor)
- Spray the pot with oil for easier clan-up.
- Place onions in the bottom of the pot, then add the beef and mushrooms.
- Mix the cornstarch with the stock, and then pour over the beef and mushrooms.
- Cover and cook on low for 8-12 hours.
I honestly don’t remember if I added salt, but certainly you can add salt or pepper to taste.






Oh my does that look good! I’m going to get this into a BBQ I am planning… great!
