  • Chopped onion
  • Garlic
  • Worcestershire sauce
  • Dijon mustard

Step 2: Sear The Patties

Heat a large skillet over medium-high heat.

5–7 minutes

  • Fresh thyme

to the skillet.

Scrape the bottom of the pan to release the flavorful browned bits.

Pour the mushroom gravy mixture into the slow cooker.

Step 5: Slow Cook The Salisbury Steak

Place the browned beef patties into the slow cooker.

Spoon some gravy over the top.

Cover and cook:

Low setting: 5–6 hours
High setting: 3–4 hours

The patties are ready when they are tender and fully cooked.

Step 6: Thicken The Gravy

Remove the Salisbury steak patties carefully.

Mix:

  • Cornstarch

to create a slurry.

Stir the slurry into the slow cooker gravy.

Cover and cook for another:

10–15 minutes

until the gravy becomes thick and smooth.
