Description

This Slow Cooker Steak and Onions recipe transforms inexpensive petite sirloin steaks into a tender, flavorful meal by slow cooking them with onions, garlic, and a savory blend of Italian dressing and brown gravy mix. The result is a comforting, effortless dish perfect for a hearty family dinner.


Ingredients

Scale

Steak and Onions

  • 2 lbs. cheap steaks (such as petite sirloins)
  • 2 white or yellow onions, cut into circles
  • ½ tsp. salt
  • ¼ tsp. pepper
  • 1 Tbsp. minced garlic

Sauce Mixture

  • 0.70 oz. Italian dressing mix packet
  • 0.87 oz. brown gravy mix
  • 1 ½ cups water
  • 3 Tbsp. cornstarch


Instructions

  1. Prepare the Steaks: Place the steaks into the slow cooker. Season evenly with ½ tsp. salt and ¼ tsp. pepper. Layer the sliced onions and minced garlic on top of the steaks to build flavor.
  2. Make the Sauce: In a small bowl, combine the Italian dressing mix packet, brown gravy mix, cornstarch, and 1 ½ cups of water. Whisk vigorously until the cornstarch is fully dissolved and the mixture is smooth.
  3. Cook Low and Slow: Pour the sauce mixture over the steak and onions inside the slow cooker. Cover and cook on the LOW setting for 5 to 6 hours, allowing the meat to become tender and the flavors to meld.
  4. Serve: Once cooked, serve the steak and onions with your preferred sides such as mashed potatoes, steamed vegetables, or a fresh salad for a wholesome meal.

Notes

  • Using inexpensive cuts like petite sirloins works best as slow cooking tenderizes the meat.
  • If you prefer a thicker gravy, you can add an additional tablespoon of cornstarch mixed with water toward the end of cooking.
  • Feel free to substitute Italian dressing mix with your favorite seasoning blends for varied flavor profiles.
  • Ensure the cornstarch is well dissolved to avoid lumps in the gravy.
  • Leftovers can be refrigerated for up to 3 days or frozen for longer storage.
