Ingredients for Beefy Onion Crockpot Meatballs

Let’s gather everything we need to make this dish shine:

For the Meatballs:

• 1 lb ground beef (85% lean recommended)
• 1 egg, lightly beaten
• ½ cup breadcrumbs (plain or seasoned)
• 1 packet onion soup mix
• 1 tsp garlic powder
• 1 tsp Worcestershire sauce
• ¼ cup milk

For the Sauce:

• 1 can (10.5 oz) condensed cream of mushroom soup
• ½ cup ketchup
• 1 tbsp Worcestershire sauce
• ½ cup beef broth (or water, in a pinch)
• 1 tbsp brown sugar

Tools You’ll Need

• Large mixing bowl
• Baking sheet (optional, if pre-browning the meatballs)
• Slow cooker
• Small whisk or fork (for mixing the sauce)

Step-by-Step Instructions to Make Beefy Onion Crockpot Meatballs

Let’s break it down so you can make these beauties without a hitch:

1. Prep the Meatballs: In a large mixing bowl, combine the ground beef, egg, breadcrumbs, onion soup mix, garlic powder, Worcestershire sauce, and milk. Use your hands to gently mix until just combined—don’t overwork the mixture, or your meatballs might turn out dense.
2. Shape and (Optional) Brown: Roll the mixture into 1-inch meatballs. You can place them directly in the crockpot, or if you prefer a firmer texture, lightly brown them in a skillet over medium heat or bake them in the oven at 400°F for 10 minutes.
3. Make the Sauce: In a separate bowl, whisk together the cream of mushroom soup, ketchup, Worcestershire sauce, beef broth, and brown sugar until smooth.
4. Assemble in the Crockpot: Pour a small amount of the sauce into the bottom of the slow cooker. Add the meatballs in layers, then pour the remaining sauce over the top.
5. Cook: Cover and cook on low for 6-8 hours or high for 3-4 hours, stirring gently once or twice to ensure even cooking.
6. Serve: Once the meatballs are tender and the sauce has thickened, they’re ready to serve. Spoon them over mashed potatoes, rice, noodles, or enjoy them as-is with a side of crusty bread.

Delicious Pairings for Your Meatballs

• Mashed Potatoes: The creamy texture perfectly complements the savory sauce.
• Buttered Egg Noodles: A simple, classic pairing that lets the meatballs shine.
• Roasted Vegetables: Balance the richness of the dish with something fresh and vibrant—try roasted carrots, green beans, or Brussels sprouts.
• Crusty Bread: Ideal for soaking up every last bit of that amazing sauce!

Tips for the Best Meatballs Ever

• Don’t Overwork the Meat: Gently mix the ingredients to keep the meatballs tender.
• Use a Cookie Scoop: This helps you portion the meatballs evenly for consistent cooking.
• Freeze for Later: Make a double batch and freeze uncooked meatballs on a baking sheet, then transfer to a freezer bag. You can cook them straight from frozen!

Storage Instructions

Have leftovers? Lucky you! Store the meatballs and sauce in an airtight container in the refrigerator for up to 4 days. To reheat, simply pop them in the microwave or warm them in a skillet over low heat, adding a splash of water or broth to loosen the sauce.

For longer storage, freeze the cooked meatballs and sauce for up to 3 months. Thaw overnight in the fridge and reheat as directed.

Frequently Asked Questions

Q: Can I use ground turkey instead of beef?
Absolutely! Ground turkey works well as a leaner option. You may need to adjust the cooking time slightly since turkey cooks faster.

Q: What if I don’t have onion soup mix?
No worries! Use 1 tablespoon of dried minced onion, ½ teaspoon garlic powder, and ½ teaspoon onion powder as a substitute.

Q: Can I make this recipe without a crockpot?
Yes! You can bake the meatballs in a 9×13-inch casserole dish with the sauce at 350°F for 30-35 minutes, or until fully cooked.
