Crockpot Sirloin Tips in Gruyère Cream Sauce Step-by-step instructions

Before you start

Before starting, cut the sirloin tips into 1-inch pieces if not already done. Dice the onion and shred the Gruyère if it's not pre-shredded.

Soften the cream cheese by leaving it at room temperature for 30 minutes or microwaving it briefly. Measure all ingredients and have them ready by the slow cooker. No need to brown the beef—the slow cooker does all the work.

Instructions

Layer and set

1. 1Layer the ingredients
   Place the sirloin steak tips in the bottom of a 6-quart slow cooker. Spread the condensed cream of mushroom soup over the beef, then scatter the diced onion on top. Add the softened cream cheese in chunks and sprinkle the shredded Gruyère over everything. Do not stir.
   Look for The ingredients are layered in the crock, with the cheese on top.
   Tip Cut the cream cheese into smaller pieces so it melts more evenly during cooking.
2. 2Add mushrooms (optional)
   If using fresh mushrooms, scatter the sliced mushrooms over the top of the cheese layer. They will release moisture and cook down into the sauce.
   Look for Mushrooms are evenly distributed over the top.
   Tip Use cremini or button mushrooms for best texture.

The raw ingredients are stacked in the slow cooker: beef on the bottom, soup and onions on top, then cream cheese and Gruyère. The cheese is still in chunks, and the soup is thick and pale. The onions are scattered evenly, and the mushrooms, if used, sit on the cheese layer. Everything looks neat and ready to cook.

Slow-cook and tenderize

3. 3Cook low and slow
   Cover the slow cooker and cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours, until the beef is fork-tender and the sauce is bubbling. Do not lift the lid during the first 4 hours on LOW or 2 hours on HIGH to keep the heat steady. Let it rest for 3 minutes before slicing.
   Look for The sauce is bubbling around the edges and the beef is tender when pierced 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.
4. 4Check temperature and rest
   Verify the beef has reached an internal temperature of at least 145°F (63°C) using an instant-read thermometer. Let the beef rest for 3 minutes before serving to allow the juices to redistribute.
   Look for Thermometer reads 145°F (63°C) or higher.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Insert the thermometer into the thickest piece of beef for an accurate reading.

After several hours, the slow cooker is filled with a bubbling, fragrant sauce. The cheese has melted into a creamy liquid, and the beef is visibly tender, with edges that shred easily.

The aroma of onions, mushrooms, and Gruyère fills the kitchen. The sauce is lightly bubbling around the edges, and the beef is fork-tender.

Finish and serve

5. 5Stir the sauce
   Gently stir the sauce to combine the melted cream cheese and Gruyère into a smooth, creamy gravy. The beef should be fork-tender and easily shred with a spoon.
   Look for The sauce is smooth and creamy, with no visible chunks of cream cheese.
   Tip Stir gently to avoid breaking up the beef too much.
6. 6Serve over toasted brioche
   Ladle the beef and sauce over toasted garlic brioche slices on a plate. Serve hot, with extra sauce spooned over the top.
   Look for The beef is glistening with sauce, and the brioche soaks up the gravy.
   Tip For extra richness, butter the brioche before toasting.

The sauce is smooth and glossy, coating the beef and mushrooms evenly. The beef is fork-tender and easily pulled apart. The toasted brioche is crisp and golden, ready to soak up the rich gravy. The dish looks hearty and inviting, with steam rising and the creamy sauce glistening.

Common mistakes

A common mistake is lifting the lid frequently to check on the dish, which releases heat and extends cooking time. Another is using low-fat cream cheese, which can separate and make the sauce grainy.

Also, avoid overcooking on HIGH for too long, as the beef can become dry and stringy. Stick to the recommended times and resist stirring until the end.

How to tell it’s done

The dish is done when the beef is fork-tender and easily pierced with a fork. The sauce should be thick and bubbling, with the cheese fully melted and smooth.

Use an instant-read thermometer to confirm the beef reaches at least 145°F (63°C) for food safety. Let the beef rest for 3 minutes before serving to allow the juices to redistribute, ensuring moist, flavorful meat.
