Slow Cooker Sour Cream Green Bean Tenderloin Tips

This slow cooker recipe delivers tender beef tenderloin tips, green beans, and potatoes in a velvety sour cream gravy with almost no effort. Just layer the ingredients, spoon over the sauce, and let the slow cooker work its magic.

Slow cooker meals are the ultimate convenience, and this one is a standout. Beef tenderloin tips cook low and slow until they are fork-tender, while green beans and russet potatoes absorb the savory gravy.

The sour cream and brown gravy mix create a creamy, deeply flavored sauce that coats every bite. Serve over buttered egg noodles for a complete meal that comes together with just 15 minutes of prep. This is the kind of recipe you will turn to again and again.

Ingredients

Why this recipe works

The slow cooker method transforms relatively lean beef tenderloin tips into exceptionally tender morsels. Cooking them on low heat for several hours allows the connective tissue to break down gently, resulting in meat that practically falls apart.

The low, moist heat also helps the potatoes and green beans cook evenly without becoming mushy, so every vegetable retains its texture.

The sour cream and brown gravy mix form a rich, velvety sauce that thickens as it cooks. The gravy mix adds depth and umami, while the sour cream provides a tangy creaminess that balances the beef. Because the ingredients are layered and not stirred, the sauce melds together slowly, creating a cohesive dish with complex flavors.

Notes and substitutions

Beef tenderloin tips are the star here, but you can also use sirloin steak cut into cubes. The key is to choose a cut that benefits from long, slow cooking.

Fresh green beans are ideal; if using frozen, add them during the last 30 minutes of cooking to prevent them from becoming too soft. Russet potatoes hold their shape well, but Yukon Golds are a great substitute.

Brown gravy mix is a pantry staple that adds instant savory flavor. You can use any brand; just check the label for gluten if needed. The egg noodles are a classic pairing, but mashed potatoes or rice also work. For a thicker sauce, let the slow cooker sit uncovered for a few minutes before serving.
