Sirloin cubes cook in beef stock and au jus seasoning until a fork goes in with no push. The juices become the sauce, so there is nothing else to make.

Ingredients

2 lb sirloin steak, cut into 1 inch cubes
1 tbsp olive oil, only if you sear
1 packet (1 oz) au jus gravy mix
1 cup unsalted beef stock
1 large yellow onion, cut into thick half-moons
4 garlic cloves, minced
1 tbsp Worcestershire sauce
1 tsp smoked paprika
1/2 tsp black pepper
2 tbsp butter, cut into pieces
1 tbsp cornstarch mixed with 2 tbsp cold water
2 tbsp chopped fresh parsley

Directions

Pat the sirloin cubes dry and season them with the pepper and smoked paprika. Dry meat takes seasoning and browns better.
If you have ten minutes, heat the olive oil in a skillet over medium-high heat and sear the cubes for 1 to 2 minutes per side in two batches. Skip this step and add the beef raw.
Spread the onion and garlic over the bottom of a 5 to 6 quart slow cooker. They lift the beef off the hot base.
Add the beef in an even layer, then sprinkle the au jus mix over the top.
Whisk the stock with the Worcestershire sauce and pour it around the edges so the seasoning stays on the meat.
Dot the butter over the top and cover with the lid.
Cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours. Start checking an hour early if your pot runs hot.
Check a cube in the middle of the pot: a fork should slide in easily, and a probe thermometer should read 195 to 205°F.
Stir the cornstarch slurry into the juices and cook on HIGH with the lid off for 10 to 15 minutes, until the sauce coats a spoon.
Taste for salt, stir in the parsley and serve over mashed potatoes, rice or egg noodles.

Notes

Stir every 30 minutes if you are home, and do not worry if you are not. Onion soup mix or a dry ranch packet can replace the au jus mix, but skip the added salt. Leftovers keep 3 to 4 days in the refrigerator and reheat gently on the stove.

What makes this one low effort

Au jus mix does the seasoning and thickening job in one packet, so the whole dish is stock, onion and beef. Sirloin cubes stay tender because the liquid is limited and the heat is gentle. The finishing butter melts into the juices and rounds everything out.

Searing first adds a deeper color, but it is optional on a busy day.

Swaps worth knowing

Onion soup mix or a ranch packet will stand in for the au jus mix. Cut back on added salt if you do. Chuck works instead of sirloin if you give it the full cook. Avoid sweet marinades, which turn the sauce sticky and heavy.

Serving ideas

Spoon it over mashed potatoes or buttered egg noodles, or pile it into toasted hoagie rolls with provolone for a quick sandwich. A side of roasted carrots keeps the plate balanced.

Make-ahead notes

It reheats best on the stove over low heat. If the sauce tightens up in the fridge, loosen it with a splash of stock or water.

Choose cubes of the same size so the beef finishes at the same time. Stir in the butter and thickener near the end, and give the sauce a few minutes to turn glossy before serving.

Hi, I'm Iren Pavlenko. I read the top-ranked slow cooker recipes for a dish side by side and write down what they disagree on and what they all leave out — the cut, the pot size, and both the LOW and HIGH times. I write these guides so your weeknight dinner doesn't turn into a dry roast because a recipe never said which of those four things mattered.
