1-First Step: Gather and Prep Your Ingredients Begin by pulling together all your ingredients to make the process smooth. Slice 6 ounces of mushrooms and half a medium yellow onion, then measure out 1 ½ cups of beef broth. For the beef patties, mix 1 ½ pounds of lean ground beef with 1 egg yolk, ¼ cup minced onion, ⅓ cup bread crumbs, 3 tablespoons milk, 1 clove minced garlic, ¾ teaspoon salt, and ¼ teaspoon black pepper in a large bowl. This prep only takes about 10 minutes, setting you up for success!

2-Second Step: Form and Brown the Patties Combine the beef patty ingredients until well mixed, then shape the mixture into six even patties. Heat a skillet over medium-high heat and brown the patties for about three minutes per side until they’re nicely seared. This step locks in flavor and helps them hold shape, and it’s a great spot to adapt for dietary needs, like using ground poultry if you’re watching red meat intake.

3-Third Step: Layer in the Slow Cooker Place the sliced mushrooms and onions at the bottom of your slow cooker for a flavorful base. Carefully layer the browned beef patties on top of the veggies. In a separate bowl, whisk together 1 ½ cups beef broth, 1 packet of brown gravy mix, 2 tablespoons ketchup, 1 teaspoon Dijon mustard, and 2 tablespoons chopped fresh parsley. Pour this mixture over the patties evenly. Cooking on low for five hours will make everything tender and juicy!

4-Fourth Step: Cook and Thicken the Sauce Turn your slow cooker to low and let it cook for five hours, filling your home with amazing smells! After the time is up, remove the patties and set them aside on a plate. Switch the slow cooker to high, mix 2 tablespoons cornstarch with 4 tablespoons cold water to make a slurry, and stir it into the broth. Let it cook for a few minutes until the sauce thickens to a gravy-like consistency. For variations, you could add more herbs here if you’re feeling creative.

5-Final Step: Serve and Enjoy Once the sauce is thickened, return the beef patties to the slow cooker to coat them thoroughly.
