Low Carb Cube Steak
Low-carb eating doesn’t mean giving up all comfort food. Many people assume ketogenic or low-carb diets must be limited to eggs and bacon, but variety and practical shortcuts are what make a plan sustainable. This recipe embraces that idea by pairing cube steak with a creamy, mushroom-forward gravy. The canned cream of mushroom soup is a pantry shortcut many people rely on—a single can contains carbohydrates, but when diluted into a sauce across multiple servings it contributes only a few carbs per portion while adding a comforting, familiar taste.
What is cube steak?
- Cube steak is typically a tenderized cut—often top round or top sirloin—that’s been pounded with a tenderizer, leaving small indentations that resemble cubes. The flattening and tenderizing help make a leaner cut cook more evenly and become more tender.
- It is sometimes sold as “minute steak” or “fast fry steak.” These thin, tenderized steaks can be treated the same as cube steak in recipes, though cooking times and methods may vary based on thickness.
Which Instant Pot should I use to make Instant Pot Cube Steak & Gravy?
A 6-quart Instant Pot or larger is recommended for this recipe. A 6-quart model has enough capacity to brown the meat in batches and finish the sauce without crowding the pot. The method should work in any comparable electric pressure cooker; adjust quantities and layering if using a smaller device.

My Top Five Instant Pot Accessories That I Think Are Worth The Money!
Helpful accessories that many home cooks find useful: an extra stainless steel inner pot, a tempered glass lid for reheating without pressure, a silicone lid for storage, extra sealing rings, and a stackable steamer rack or trivet. These items improve versatility and make cleanup easier, especially when you use your Instant Pot frequently.
How do you make cube steak tender?
- The name “cube steak” comes from the small square indentations left by the tenderizer. Those marks are a sign the meat has been flattened and tenderized to break down muscle fibers.
- Cube steak benefits from longer, gentler cooking so the connective tissue can soften—pressure cooking or slow cooking are both good approaches. Quick fast-fry methods can leave it tough if the meat is not given enough time to break down.
- Minute steak and cube steak are similar in appearance, but minute steak is generally just thinly sliced and lightly pounded. Labels vary by butcher and region, so pay attention to texture and thickness when you buy steak for this recipe.
Is cube steak the same as ground beef?
No. Cube steak is a whole-muscle cut that has been tenderized and flattened. It can sometimes look textured in photos because of the tenderizer marks, but it is not ground or processed like ground beef.

Recipe Notes
You can swap beef or brown gravy mix for the mushroom gravy packet if you prefer, though the mushroom mix enhances the mushroom flavor when paired with canned mushrooms. Choose low-sodium soup and gravy products to reduce the overall sodium content.
