Before you start
Before starting, cut the ribeye into 1-inch cubes and season lightly with salt and pepper if desired. Slice the portobello mushrooms thickly and peel the shallots, cutting them in half if large.
Soften the cream cheese to room temperature for easier melting. Shred the Gruyère cheese if not pre-shredded. Have all ingredients measured and ready to layer in the slow cooker. No need to brown the beef first—the slow cooker does all the work.
Ingredients at a glance (6)
- 2 lb ribeye steak, cut into 1-inch cubes
- 8 oz portobello mushrooms, thickly sliced
- 6 shallots, peeled and halved
- 8 oz cream cheese, softened
- 1 1/2 cups shredded Gruyère cheese
- 4 slices toasted garlic brioche slices
Instructions
Layering the Ingredients
- Layer the IngredientsPlace the cubed ribeye steak evenly in the bottom of a 6-quart slow cooker. Scatter the sliced portobello mushrooms and halved shallots over the beef. Drop the softened cream cheese by spoonfuls over the top, then sprinkle with the shredded Gruyère cheese.Look for The slow cooker will be full but not overflowing; the ingredients should be in distinct layers.Tip For even cooking, try to spread the beef in a single layer as much as possible.
At the end of this phase, the slow cooker contains distinct layers: beef on the bottom, mushrooms and shallots on top, and the cream cheese and Gruyère scattered over. The ingredients are raw but arranged for even cooking.
The slow cooker should be about two-thirds full. Check that the beef is spread evenly and the cheese is distributed. This layering ensures the flavors meld as they cook.
Slow Cooking to Tender
- Slow Cook Until TenderCover the slow cooker and cook on LOW for 4 to 5 hours, or on HIGH for 2 1/2 to 3 hours, until the beef is fork-tender and the sauce is bubbling. Stir gently once halfway through if possible, but avoid over-stirring to keep the beef intact. Let it rest for 3 minutes before slicing.Look for The sauce will be thick and bubbly, and the beef should shred easily with a fork.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip If the sauce seems thin at the end, remove the lid and cook on HIGH for 15–20 minutes to reduce.
After 4-5 hours on LOW, the sauce is bubbling and the beef is fork-tender. The cream cheese and Gruyère have melted into a smooth, creamy sauce that coats the meat and mushrooms. The shallots are soft and sweet, and the mushrooms have released their juices. The aroma is rich and savory. Gently stir once to combine, but avoid over-stirring to keep the beef in chunks.
Resting and Serving
- Rest and ServeTurn off the slow cooker and let the dish rest for at least 5 minutes. The internal temperature of the beef should reach 145°F (63°C) for medium-rare, or cook longer for well-done. Serve hot over toasted garlic brioche slices, spooning extra sauce over the top.Look for The beef is fork-tender and the sauce has thickened slightly as it rests.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Letting the dish rest allows the juices to redistribute and the sauce to settle.
After turning off the slow cooker, the dish rests for 5 minutes. The sauce thickens slightly, and the beef reaches its final internal temperature. The beef is tender and easily pierced with a fork, and the sauce is glossy and rich. Serve the beef and sauce over toasted brioche, spooning extra sauce on top. The dish is ready to enjoy.
Common mistakes
One common mistake is overcooking the beef, which can make it dry despite the sauce. Stick to the recommended cooking times and check for doneness early. Another mistake is using pre-shredded cheese, which often contains anti-caking agents that prevent smooth melting—shred your own for the best texture.
Also, avoid lifting the lid frequently, as this releases heat and extends cooking time. Finally, don't skip the resting period; it helps the sauce set and the meat stay juicy.
How to tell it’s done
The dish is done when the beef is fork-tender and the sauce is hot and bubbling. The internal temperature of the beef should reach at least 145°F (63°C) for medium-rare, but many prefer it cooked longer for a more well-done texture.
The mushrooms should be soft and the shallots translucent. Let the dish rest for 5 minutes before serving to allow the sauce to thicken slightly and the flavors to meld.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
