Ingredients

Why this recipe works

The slow cooker is the ideal tool for sirloin tips. The low, moist heat breaks down the connective tissue in the meat, turning it from a tough cut into spoon-tender bites.

Cooking the beef low and slow also allows the flavors to meld—the beef juices mix with the sour cream and gravy mix, creating a deeply savory sauce that you can't get from a quick sear.

Layering the asparagus on top of the beef means it steams rather than boils, so it keeps its bright color and a slight snap. The garlic cloves soften and mellow as they cook, infusing the sauce with a gentle aromatic sweetness. This method ensures every component is cooked perfectly without any extra steps.

Notes and substitutions

For the best results, use top sirloin steak tips—they're already cut into bite-sized pieces and have good marbling. If you can only find a whole sirloin, cut it into 1-inch cubes yourself.

The asparagus should be fresh and trimmed; thick spears hold up better to the long cooking time. Smashed garlic cloves release more flavor than whole cloves, but don't chop them too finely or they might burn.

The brown gravy mix is the secret to the rich, glossy sauce. It thickens the sour cream as it heats, preventing it from curdling.

You can use any brand of brown gravy mix, or substitute with a homemade mix of flour and beef broth. If you prefer a thicker sauce, you can stir in a cornstarch slurry at the end, but the video doesn't show that step.
