Slow-Cooker Bourbon Gravy Portobello Ribeye Bites Step-by-step instructions

Before you start

Before you start, cut the ribeye into 1-inch cubes if not already done. Thickly slice the portobello caps and peel the shallots, halving any large ones. Measure the gravy and cut the butter into four pats.

Have your slow cooker ready. There is no need to brown the beef or sauté the mushrooms—everything goes in raw, which keeps prep to just minutes. Set out serving plates and have the cooked rice ready before the cooking time ends.

Instructions

Layer and Start

1. 1Layer the Ingredients
   Place the cubed ribeye bites in the bottom of a 6- to 7-quart slow cooker in an even layer. Scatter the thickly sliced portobello mushroom caps and the peeled, halved shallots over the beef. Pour the mushroom-bourbon gravy over everything, then dot the top with the pats of salted butter. Do not stir.
   Look for The beef, mushrooms, and shallots are layered in the slow cooker with gravy and butter on top.
   Tip Keep the ingredients in distinct layers rather than stirring—they will meld as they cook.
2. 2Cover and Cook
   Cover the slow cooker with the lid. Cook on LOW for 6 to 8 hours, or on HIGH for 3 to 4 hours, until the beef is fork-tender and the mushrooms are silky. The gravy will darken and thicken slightly as the beef releases its juices.
   Look for The beef is fork-tender and the gravy is bubbling gently around the edges.
   Tip Resist lifting the lid during cooking—each peek releases heat and adds time.

At the end of this phase, the slow cooker contains neat layers of raw beef, mushrooms, shallots, gravy, and butter. The ingredients are not stirred, and the butter pats sit on top.

The slow cooker is covered and set to cook. The raw beef is safe as long as it is refrigerated until ready to cook and cooked within the recommended time.

Slow-Cook to Tender

3. 3Check the Beef
   After the minimum cooking time, use tongs to lift a piece of beef from the center of the slow cooker. It should be very tender and easily pull apart with a fork. If not, continue cooking for another 30 minutes and check again. Let it rest for 3 minutes before slicing.
   Look for The beef is tender and shreds easily with a fork.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip If the gravy seems thin, leave the lid off for the last 15 minutes to let it reduce slightly.
4. 4Rest the Meat
   Turn off the slow cooker and let the beef rest in the warm gravy for at least 3 minutes before serving. This allows the juices to redistribute and ensures each bite is moist and tender.
   Look for The beef rests in the hot gravy, absorbing flavor and staying juicy.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting is brief but essential—don't skip it.

The beef is fork-tender and the gravy is bubbling gently around the edges. The mushrooms are silky, and the shallots are soft and translucent. The kitchen smells richly of bourbon and mushrooms. The beef has reached at least 145°F (63°C) and is resting in the hot gravy before serving.

Serve and Enjoy

5. 5Serve Over Rice
   Spoon fluffy white rice onto serving plates. Ladle the beef, mushrooms, shallots, and plenty of bourbon gravy over the rice. Serve hot, ensuring each plate gets a generous portion of the glossy sauce.
   Look for The dish is served steaming over rice with extra gravy spooned on top.
   Tip Warm the plates beforehand to keep the dish hot longer.

The dish is served over fluffy white rice, with the beef, mushrooms, and shallots coated in glossy bourbon gravy. The plates are steaming hot, and the sauce pools around the rice. Each bite is tender, savory, and rich. The remaining portions can be cooled and refrigerated within 2 hours.

Common mistakes

A common mistake is lifting the lid too often to check on the food—each time you do, heat escapes and the cooking time extends. Trust the process and keep the lid on until the minimum time is up.

Another pitfall is using lean beef, which can dry out during long cooking; choose well-marbled ribeye or add a bit of extra butter. Finally, don't skip the resting time after cooking—it ensures the meat stays juicy. If the gravy is too thin, simmer with the lid off to reduce.

How to tell it’s done

The dish is done when the beef is fork-tender and easily pulls apart with no resistance. Use tongs to lift a piece from the center of the slow cooker to test. The mushrooms should be silky and fully softened, and the shallots should be sweet and translucent.

The gravy will be bubbling gently and slightly thickened. For food safety, the beef must reach an internal temperature of at least 145°F (63°C); let it rest for at least 3 minutes before serving to allow the juices to settle.
