Step-by-Step Cooking Instructions

Cooking Beefy Onion Crockpot Meatballs is easy, especially with a slow cooker. Follow these simple steps to get the perfect results:
- Prepare the Meatballs: In a large bowl, combine ground beef, breadcrumbs, egg, Parmesan cheese, parsley, salt, pepper, garlic powder, onion powder, and Worcestershire sauce. Mix until well combined.
- Shape the Meatballs: Roll the meat mixture into 1-1.5 inch meatballs. You should have about 16-18 meatballs, depending on the size.
- Sear the Meatballs (Optional): For added flavor, you can sear the meatballs in a skillet over medium heat with a tablespoon of oil until browned on all sides. This step is optional but enhances the flavor and texture.
- Prepare the Sauce: In a separate bowl, whisk together the onion soup mix, beef broth, ketchup, barbecue sauce, brown sugar, Worcestershire sauce, and Dijon mustard until smooth.
- Assemble in the Crockpot: Place the meatballs in the crockpot and pour the sauce mixture over them. Gently toss to coat the meatballs evenly with the sauce.
- Cook: Cover and cook on low for 4-5 hours or on high for 2-3 hours. The meatballs should be tender and well-cooked, and the sauce will have thickened slightly.
How to Cook Beefy Onion Crockpot Meatballs: A Step-by-Step Guide
- Mix and Form Meatballs: Start by mixing all the ingredients for the meatballs in a large bowl until fully incorporated. Shape them into evenly sized balls to ensure even cooking.
- Sear for Extra Flavor: If you have time, searing the meatballs in a skillet can add an extra layer of flavor, giving them a slightly caramelized exterior.
- Combine Ingredients for the Sauce: In another bowl, whisk all the sauce ingredients together until fully blended. This ensures the flavors meld together in the crockpot.
- Arrange in Crockpot: Place the meatballs in the crockpot in a single layer, then pour the sauce over them. Stir gently to ensure all meatballs are covered.
- Slow Cook: Set your crockpot to low or high based on your time preference, and let it work its magic. Check occasionally to ensure the sauce doesn’t thicken too much; if it does, add a splash of water or beef broth.
Common Mistakes to Avoid
- Overcrowding the Crockpot: Make sure the meatballs are arranged in a single layer, if possible, so they cook evenly.
- Skipping the Searing Step: Although optional, searing adds depth to the flavor, so try not to skip it.
- Overcooking: Keep an eye on the time. Overcooking can make the meatballs dry. If in doubt, use a meat thermometer to ensure they’re done without drying out.
- Using Too Much Salt: Since the onion soup mix and beef broth are salty, taste the sauce before adding additional salt.
