Before you start
Before beginning, ensure that your slow cooker is clean and placed on a stable, heat-resistant surface. Have all ingredients measured out and ready to go.
If your frozen meatballs are stuck together, gently break them apart before adding them to the slow cooker to ensure they cook evenly. Ensure your beef broth is at room temperature to prevent any drastic temperature drops when adding it to the slow cooker basin.
Ingredients at a glance (4)
- 24 oz frozen precooked beef meatballs
- 1 large yellow onion, thinly sliced
- 1 packet au jus seasoning mix
- 2 cups beef broth
Instructions
Preparation and assembly
- Assemble the slow cookerPlace the frozen precooked beef meatballs into the basin of the slow cooker, ensuring they are distributed in an even layer across the bottom for consistent heating throughout the cooking process.Look for Meatballs are arranged in a single, even layer.Tip Using a slow cooker liner can make cleanup significantly easier after the meal is served.
The meatballs should be layered uniformly in the slow cooker basin, providing a solid foundation for the remaining ingredients. The onions should be scattered evenly to ensure they cook down uniformly into the broth, and the seasoning should be distributed across the surface to prevent clumping during the initial heating phase.
Seasoning and broth addition
- Add aromatics and seasoningsScatter the thinly sliced yellow onions over the meatballs. Sprinkle the au jus seasoning mix evenly over the top of the onions and meatballs to ensure the seasoning is well distributed.Look for Onions are spread out and seasoning covers the surface.Tip Do not stir the contents yet to keep the seasoning concentrated on the top layer.
At this stage, the au jus mix should be visibly covering the onion and meatball layer. The beef broth should be poured gently to avoid displacing the seasoning. The slow cooker should be set to the appropriate low heat to begin the gradual infusion of flavors, with the lid secured tightly to retain moisture and heat.
Final cooking and gravy development
- Pour and cookPour the beef broth over the mixture. Cover the slow cooker and cook on low for 4 hours until the meatballs reach an internal temperature of 160°F (71°C) and the onions are soft.Look for Meatballs are heated through and the liquid has formed a savory gravy.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Check the temperature of the largest meatball to ensure it is thoroughly cooked.
The final phase involves letting the ingredients simmer undisturbed. The meatballs should be hot throughout, and the gravy should have a deep, savory aroma.
The onions should be soft and integrated into the broth, and the sauce should appear slightly glossy, indicating that the flavors have successfully melded into a cohesive, delicious sauce.
Common mistakes
A common mistake is over-stirring the ingredients, which can cause the meatballs to break apart before they are fully heated. Avoid opening the slow cooker lid frequently, as each time you lift the lid, heat escapes and the total cooking time increases.
Additionally, do not use a high-heat setting for too long, as this can result in the meatballs becoming tough and rubbery rather than tender and juicy.
How to tell it’s done
The meatballs are done when they are heated through and reach a safe internal temperature of 160°F (71°C). You can verify this by inserting a meat thermometer into the center of one of the larger meatballs.
The onions should be visibly translucent and very tender, and the liquid should be bubbling gently and have taken on a rich, dark brown color characteristic of a traditional au jus.
- Ground meat: 160°F (71°C) in the thickest part
