Sour Cream Pearl Onion Sirloin Tips: Easy Crockpot Dinner Step-by-step instructions

Before you start

Before starting, pat the sirloin tips dry with paper towels. If the pearl onions are not pre-peeled, blanch them in boiling water for 1 minute, then slip off the skins.

Crinkle-cut carrots can be found pre-cut in the produce section, or cut regular carrots into thick coins. Measure the sour cream and gravy mix so everything is ready to layer. No other prep is needed—no browning, no sautéing.

Instructions

Layer and Cook

1. 1Layer the Ingredients
   Place the sirloin steak tips in the bottom of a 7-quart slow cooker in an even layer. Scatter the pearl onions and crinkle-cut carrots over the beef. Dollop the sour cream over the top, then sprinkle the brown gravy mix evenly over everything. Do not stir.
   Look for The ingredients should be layered in the order added, with the gravy mix on top.
   Tip Keep the sour cream in dollops rather than spreading it; this helps it melt into the gravy as it cooks.
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 reaches an internal temperature of 145°F (63°C) or higher. The sauce will thicken as the sour cream melts and combines with the gravy mix. Let it rest for 3 minutes before slicing.
   Look for The beef should be easily pierced with a fork and the sauce should be bubbling gently around the edges.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Avoid lifting the lid during cooking to keep the heat and moisture consistent.

After layering, the raw beef, onions, carrots, sour cream, and gravy mix sit in distinct layers. As it cooks, the sour cream melts, and the gravy mix dissolves, creating a bubbling sauce.

The aroma of beef and onions fills the kitchen. The beef should be fork-tender and the sauce thickened by the end of this phase.

Rest and Noodles

3. 3Rest the Beef
   Once the beef is cooked through, turn off the slow cooker. Let the beef rest in the sauce for at least 3 minutes before serving. This allows the juices to redistribute and ensures tender slices.
   Look for The beef should rest in the warm sauce; the gravy will settle slightly.
   Tip Resting is quick but important—don't skip it.
4. 4Cook the Noodles
   While the beef rests, cook the egg noodles according to package directions in salted boiling water. Drain and toss with butter. Keep warm until serving.
   Look for Noodles should be tender but still firm to the bite.
   Tip Reserve a little pasta water to loosen the noodles if they stick.

The beef rests in the warm sauce, allowing the juices to redistribute. The noodles cook in salted water until tender. The kitchen smells of rich beef and butter. The noodles are drained and tossed with butter, ready to serve.

Serve and Enjoy

5. 5Serve Over Noodles
   Spoon the warm buttered noodles onto serving plates. Ladle the sirloin tips, vegetables, and gravy over the top. Serve immediately.
   Look for The gravy should coat the beef and noodles generously.
   Tip For a prettier plate, twirl the noodles into a nest before adding the beef.

The final dish features tender beef and vegetables coated in a glossy, mahogany gravy over buttered noodles. The sauce is creamy and savory, with a slight tang from the sour cream. Everything is hot and ready to eat.

Common mistakes

One common mistake is lifting the lid to check on the food, which releases heat and extends cooking time. Another is using low-fat sour cream, which can curdle.

Also, avoid stirring the ingredients during cooking—this can break up the beef and make the sauce cloudy. Finally, don't skip the rest time; cutting into the beef too soon will cause the juices to run out.

How to tell it’s done

The beef is done when it is fork-tender and shreds easily, and an instant-read thermometer inserted into the thickest piece registers 145°F (63°C) for medium-rare, or higher if you prefer well-done.

The sauce should be thick enough to coat the back of a spoon, and the vegetables should be soft but not mushy. Let the beef rest at least 3 minutes before serving to lock in the juices.
