Ingredients
For the Meatballs:
- 1.5 lbs ground beef
- 1/2 cup breadcrumbs
- 1/4 cup finely chopped onion
- 1 egg, lightly beaten
- 2 tablespoons Worcestershire sauce
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon black pepper
- 1/4 teaspoon salt (or to taste)
- 1 tablespoon olive oil (for browning)
For the Salisbury Steak Sauce:
- 2 tablespoons butter
- 1 medium onion, sliced
- 8 oz sliced mushrooms
- 3 tablespoons all-purpose flour
- 2 cups beef broth
- 2 tablespoons tomato paste
- 2 tablespoons Worcestershire sauce
- 1 teaspoon Dijon mustard
- 1/2 teaspoon dried thyme
- 1/4 teaspoon black pepper
- 1/4 teaspoon salt (or to taste)
Let’s Make Some Magic: Preparing the Meatballs
Alright, friend! Let’s get started on these delectable meatballs. Don’t worry, it’s easier than you think!
Mixing the Meatball Mixture:
- In a large bowl, gently combine the ground beef, breadcrumbs, onion, egg, Worcestershire sauce, garlic powder, onion powder, pepper, and salt. Try not to overmix, as this can make the meatballs tough.
- Using your hands (or a cookie scoop for uniformity!), form the mixture into evenly sized meatballs, about 1-1.5 inches in diameter.
Browning for Flavor (Optional, but Recommended):
- Heat the olive oil in a large skillet over medium-high heat.
- Brown the meatballs in batches, turning occasionally, until they are browned on all sides. This step adds a beautiful color and depth of flavor, but if you’re short on time, you can skip it – the slow cooker will still do its job.
- Remove the browned meatballs from the skillet and set aside.
Crafting the Salisbury Steak Sauce
Now, for the star of the show: the Salisbury steak sauce! This is where all the savory goodness comes from.
Sautéing the Aromatics:
- In the same skillet you used to brown the meatballs (don’t worry about cleaning it!), melt the butter over medium heat.
- Add the sliced onion and cook until softened and translucent, about 5-7 minutes.
- Add the sliced mushrooms and cook until they are tender and have released their moisture, about 5-7 minutes more.
Building the Sauce:
- Sprinkle the flour over the onion and mushroom mixture and cook for 1 minute, stirring constantly. This creates a roux that will thicken the sauce.
- Gradually whisk in the beef broth, making sure to scrape up any browned bits from the bottom of the skillet. Those bits are packed with flavor!
- Stir in the tomato paste, Worcestershire sauce, Dijon mustard, thyme, pepper, and salt. Bring the sauce to a simmer, stirring occasionally, until it thickens slightly, about 5-7 minutes.
Slow Cooker Assembly: The Grand Finale
Almost there! Now, let’s let the slow cooker work its magic.
Layering and Cooking:
- Pour about half of the Salisbury steak sauce into the bottom of your slow cooker.
- Arrange the browned meatballs (or unbrowned, if you skipped that step) in a single layer over the sauce.
- Pour the remaining sauce over the meatballs, making sure they are well coated.
- Cover the slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours.
