Best Crock Pot Recipe for Sirloin Steak!

Tender. Sirloin steak is the perfect steak for a crock pot. It does so much better when it's cooked low and slow - and given time to tenderize.

Delicious. The combination of ranch seasoning, gravy mix, and balsamic vinegar, gives this steak the most awesome flavor.

Easy. Mix the sauces then dump it all in my friends! No special trick. Thicken the gravy if needed by adding more cornstarch at the end.

Ingredients You'll Need To Make This Slow Cooker Sirloin Steak

5 ingredients for making crock pot sirloin steak laying on a white wooden table.

Here are the ingredients you will need to make this top sirloin steak in crock pot recipe:

  • Top Sirloin Steak: thinly sliced. Round steak or flank steak may also be used.
  • Low-Sodium Beef Broth: Beef broth or beef stock may be used. It is best to use low-sodium because the ranch seasoning and brown gravy have a higher salt content.
  • Ranch Seasoning Mix: a simple ready-made seasoning mix.
  • Balsamic Vinegar: helps to tenderize the meat and give it a little tang. Worcestershire can also be substituted.
  • Brown Gravy Mix: any brand of dried brown gravy mix. I used brown gravy mix over an au jus mix for the thickening ingredients that it contains.
  • Cornstarch: used to thicken the gravy.

For exact ingredient quantities, please see the recipe card below!

  • Bump up the flavor with garlic powder or onion powder.
  • Butter can be added to give it even more richness and flavor.
  • Sliced fresh carrots and potatoes can be added directly to the pot to cook alongside the sirloin steak.
  • Onion soup mix can be substituted for the brown gravy mix. Additional cornstarch will be needed.

Notes

For more helpful hints, substitution ideas, cooking tips, and other delicious recipes check out my post above.
TIPS: Slice the steak thinly so it cooks evenly and stays tender. Use low-sodium broth because the ranch and gravy mixes are already salty. Don’t lift the lid for the first 4 hours, since each peek adds about 20 minutes of cooking time. To thicken the gravy, remove the steak, turn the crock pot to HIGH, whisk 1 tablespoon of cornstarch with 2 tablespoons of cold water, stir it in, and cook uncovered until thickened. Store leftovers in the fridge for up to 4 days or freeze for up to 4 months.
VARIATIONS: Add sliced carrots and halved baby potatoes to cook with the steak. Add red pepper flakes for heat, or garlic powder or onion powder for more flavor. Stir in a pat of butter for an even richer gravy. Serve over mashed potatoes or rice with sweet corn or peas.
SUBSTITUTIONS: Use Worcestershire sauce instead of balsamic vinegar. Round steak or flank steak can replace the sirloin. Onion soup mix can replace the brown gravy mix, but you will need a little more cornstarch. Regular beef broth or stock works if you cut back on salt.

    For high cook do you do 3 hours?

      Hi Sara! Yes, if you’re cooking on high, about 3 hours is just right for the sirloin to get tender and soak up all that cozy gravy flavor. Hope you enjoy it! 😊

      This recipe calls for thinly sliced steak. As long as it's thinly sliced you should be fine. If it's not then I found that it's best to partially thaw the steak - just enough so I could slice through it.
