● 1 tablespoon cornstarch mixed with 2 tablespoons cold water, optional

👩🍳 Instructions
Step 1: Prepare the Ingredients
Start by chopping the onion into small pieces and mincing the garlic. Measure out your seasonings, beef broth, Worcestershire sauce, tomato paste, and other gravy ingredients so everything is ready before you begin cooking.
For extra flavor, you can use sliced mushrooms or add a little Dijon mustard to the gravy. These ingredients bring additional depth without making the recipe complicated.
Step 2: Brown the Ground Beef
Although you can prepare ground beef in a slow cooker, browning it first is recommended for the best flavor and food safety.
Heat a large skillet over medium-high heat. Add the ground beef and break it into small pieces with a wooden spoon or spatula. Cook until the beef is browned and no longer pink, stirring occasionally.
If your beef releases a lot of fat, carefully drain the excess grease. This helps prevent the finished gravy from becoming oily.
Add the chopped onion and cook for another 3–4 minutes, until it begins to soften. Stir in the minced garlic and cook for approximately 30 seconds, just until fragrant.
Step 3: Season the Beef
Sprinkle the salt, black pepper, paprika, onion powder, garlic powder, and Italian seasoning over the browned beef.
Stir everything together until the meat is evenly coated with the seasonings. Add the Worcestershire sauce and tomato paste, mixing well to distribute their rich, savory flavors.
Allow the mixture to cook for another minute before transferring it to the slow cooker.
Step 4: Prepare the Onion Gravy
In a medium bowl, whisk together the beef broth, soy sauce, dried thyme, and flour until the mixture is as smooth as possible.
Pour this liquid over the beef and onions in the slow cooker. Stir gently to combine all the ingredients.
If you are adding mushrooms, arrange them over the beef mixture now. Add the bay leaf if desired, making sure to remove it before serving.
The liquid should create a flavorful base for the gravy as the beef cooks slowly.
Step 5: Slow Cook Until Tender
Cover the slow cooker with its lid and cook on LOW for 4–6 hours or on HIGH for approximately 2–3 hours, depending on your appliance and the quantity of ingredients.
Stir once or twice if convenient, but avoid lifting the lid too frequently because this releases heat and increases cooking time.
Since the beef has already been browned, the slow cooker allows the seasonings, onions, and gravy to develop a deeper flavor while the ingredients gently simmer together.
Use a food thermometer to ensure the ground beef mixture reaches at least 160°F (71°C). Keep the finished dish hot until serving.
Step 6: Thicken the Gravy
When cooking is complete, check the consistency of the gravy. If it is already thick and rich, you can move directly to the next step.
For a thicker sauce, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water in a small bowl. Stir until smooth, then pour the mixture into the slow cooker.
Stir well, cover, and cook on HIGH for another 10–15 minutes, or until the gravy thickens.
For an extra silky finish, stir in a tablespoon of butter just before serving. Taste the sauce and adjust the salt and pepper if necessary.
Step 7: Serve and Enjoy
Remove the bay leaf, if used, and give the beef mixture a final stir. Sprinkle fresh chopped parsley over the top for a little color and freshness.
Serve the juicy ground beef and onion gravy over creamy mashed potatoes, fluffy white rice, buttered egg noodles, or baked potatoes.
Spoon plenty of gravy over each serving to make the meal extra delicious. Add steamed green beans, roasted carrots, or a fresh green salad for a complete family dinner.
🍽️ Serving Suggestions
This versatile slow cooker recipe works with many different side dishes.

For a heartier version, you can also add diced potatoes and carrots to the slow cooker. Cut them into similarly sized pieces so they cook more evenly.
💡 Tips for the Best Results
Brown the beef first. This develops a deeper, richer flavor and allows you to drain excess fat before slow cooking.
Avoid adding too much liquid. Ground beef releases moisture as it cooks, so the gravy should be flavorful without becoming watery.
Whisk the gravy ingredients thoroughly. Mixing the flour with the cold broth before adding it to the slow cooker helps reduce lumps.
Adjust the seasonings at the end. Broths and soy sauces vary in saltiness, so taste the finished gravy before adding more salt.
Make it your own. Add mushrooms, a pinch of chili flakes, or a teaspoon of Dijon mustard to customize the flavor.
Store leftovers safely. Transfer leftovers to airtight containers and refrigerate within two hours. Enjoy within 3–4 days, reheating until the beef mixture reaches 165°F (74°C). You can also freeze portions for up to 3 months for convenient future meals.
