Ingredients

  • pounds ground beef
  • ½ cup diced onion
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 10.5-ounce can French onion soup
  • 1 packet French onion soup mix
  • 1 cup beef broth
  • pounds baby potatoes halved
  • 1 tablespoon cornstarch
  • 2 tablespoons water
  • 4 slices provolone cheese
  • Parsley for garnish

Instructions

  • Step 1: Brown the Beef - In a skillet over medium heat, cook the ground beef until it is fully browned. This step builds flavor and prevents excess grease in the slow cooker. Drain any remaining fat.
  • Step 2: Transfer to the Slow Cooker - Carefully transfer the cooked ground beef into the slow cooker, spreading it evenly across the bottom.
  • Step 3: Add the Potatoes and Onion - Add the halved baby potatoes and diced onion to the slow cooker. These ingredients will absorb the rich flavors as they cook.
  • Step 4: Prepare the French Onion Mixture - In a mixing bowl, combine the salt, black pepper, garlic powder, French onion soup, French onion soup mix, and beef broth. Stir until well blended.
  • Step 5: Combine Everything - Pour the onion mixture over the beef and potatoes. Stir gently to ensure everything is evenly coated.
  • Step 6: Slow Cook to Perfection - Cover and cook on low for 4 to 5 hours, or until the potatoes are fork tender and infused with flavor.
  • Step 7: Thicken the Gravy - In a small bowl, whisk together the cornstarch and water until smooth. Stir the mixture into the slow cooker.
  • Step 8: Allow the Sauce to Thicken - Cover and cook for an additional 10 to 15 minutes, allowing the sauce to transform into a rich and velvety gravy.
  • Step 9: Stir Before Serving - Gently stir the contents so the potatoes and beef are coated in the savory French onion gravy.
  • Step 10: Add Cheese and Garnish - Top with slices of provolone cheese and allow them to melt. Finish with a sprinkle of fresh parsley before serving.
