What are Beefy Onion Crockpot Meatballs?
Beefy Onion Crockpot Meatballs are tender, flavorful meatballs made from ground beef and seasoned with a rich onion flavor. These meatballs are simmered slowly in a crockpot, absorbing all the juicy goodness and melding with a delicious sauce. The beauty of this recipe is its simplicity—it requires minimal prep work, and the slow cooker does the rest. The onion flavor comes through in the form of onion soup mix or freshly chopped onions, giving the meatballs a deliciously sweet, savory taste. Let’s dive into the ingredients you’ll need to make these savory meatballs.
Ingredients List for Beefy Onion Crockpot Meatballs
To make the meatballs:
- Ground Beef (1.5 to 2 pounds): Ground beef is the base of this dish. You want a balance between flavor and texture, so using ground beef with around 80-85% lean is recommended.
- Eggs (2 large): Eggs act as the binder, keeping the meatballs together.
- Breadcrumbs (1 cup): Regular or Italian-style breadcrumbs provide the structure for the meatballs.
- Onion Soup Mix (1 packet): This adds a rich, savory onion flavor to the meatballs without needing to chop fresh onions.
- Garlic Powder (1 teaspoon): Adds a subtle but delicious garlic flavor to enhance the taste.
- Milk (¼ cup): Keeps the meatballs moist and tender.
- Salt and Pepper (to taste): Adjust based on your preference.
For the sauce:
- Beef Broth (2 cups): Provides a rich and savory base for the sauce.
- Worcestershire Sauce (2 tablespoons): Adds a deep umami flavor to the sauce.
- Ketchup (¼ cup): Gives the sauce a bit of sweetness and tang.
- Onion (1 medium, chopped): Enhances the onion flavor and adds texture to the sauce.
- Brown Sugar (2 tablespoons): Balances the tanginess of the ketchup with a touch of sweetness.
- Cornstarch (2 tablespoons mixed with 2 tablespoons of water): This slurry thickens the sauce to a nice consistency as it cooks.
Ingredients List for Beefy Onion Crockpot Meatballs (Vegetarian/Vegan Option)
For those looking to enjoy this dish without meat, here’s a quick substitution guide to make a vegetarian or vegan version of beefy onion crockpot meatballs:
To make the meatballs:
- Plant-Based Ground “Meat” (1.5 to 2 pounds): Substitute ground beef with a plant-based alternative like Beyond Meat or Impossible Foods.
- Flax Egg (2 tablespoons ground flaxseed + 6 tablespoons water): Instead of eggs, use flax eggs for binding in vegan versions.
- Vegan Breadcrumbs (1 cup): Look for breadcrumbs that are dairy and egg-free.
- Vegan Onion Soup Mix (1 packet): Ensure the onion soup mix you use is vegan.
- Garlic Powder (1 teaspoon): Garlic adds the same burst of flavor.
- Plant-Based Milk (¼ cup): Use almond, oat, or soy milk to keep the meatballs moist.
- Salt and Pepper (to taste): Season according to taste.
For the sauce:
- Vegetable Broth (2 cups): Use vegetable broth in place of beef broth for a vegan-friendly sauce.
- Vegan Worcestershire Sauce (2 tablespoons): Many Worcestershire sauces contain fish, but there are vegan alternatives available.
- Tomato Paste (¼ cup): A more natural, vegan-friendly option to replace ketchup.
- Chopped Onion (1 medium): Onions are naturally vegan and a must for flavor!
- Brown Sugar (2 tablespoons): Double-check to ensure it’s vegan, as some sugars are processed with bone char.
- Cornstarch Slurry (2 tablespoons mixed with 2 tablespoons water): Cornstarch is naturally vegan and will help thicken your sauce.
Substitutions and Variations
This recipe is very flexible, so you can easily switch up ingredients depending on your preferences or dietary restrictions.
- Turkey Meatballs: If you prefer a lighter option, you can replace the ground beef with ground turkey. This makes the dish leaner but still delicious.
- Gluten-Free Option: To make this recipe gluten-free, use gluten-free breadcrumbs and ensure that your onion soup mix and Worcestershire sauce are gluten-free as well.
- Cheesy Meatballs: For a richer twist, you can stuff the meatballs with a cube of mozzarella or cheddar cheese before rolling them. This adds a delightful cheesy surprise in every bite.
- Spicy Meatballs: If you love a bit of heat, add ½ teaspoon of crushed red pepper flakes or a few dashes of hot sauce into the meatball mixture.
- Herb-Infused Meatballs: Add a tablespoon of chopped fresh herbs like parsley, thyme, or oregano for extra freshness.
Step-by-Step Cooking Instructions
Now, let’s go over how to prepare these delicious Beefy Onion Crockpot Meatballs.

- Prepare the Meatball Mixture: In a large mixing bowl, combine the ground beef, eggs, breadcrumbs, onion soup mix, garlic powder, milk, salt, and pepper. Use your hands or a spoon to mix until all ingredients are well combined. Don’t overwork the meat mixture, or the meatballs can become tough.
- Shape the Meatballs: Scoop out about 1½ tablespoons of the mixture and roll it between your hands to form evenly sized meatballs. Place them on a baking sheet lined with parchment paper. This should make about 20-24 meatballs, depending on the size.
- Brown the Meatballs: (Optional but recommended) In a large skillet, heat a little oil over medium heat. Brown the meatballs on all sides, which seals in the juices and adds extra flavor. You don’t need to cook them through as they’ll finish cooking in the crockpot.
- Prepare the Sauce: In your crockpot, combine the beef broth, Worcestershire sauce, ketchup, chopped onion, and brown sugar. Stir everything together until well mixed.
- Add the Meatballs to the Crockpot: Gently place the meatballs into the sauce in the crockpot. Be sure they are fully submerged in the sauce.
- Cook on Low: Cover the crockpot with a lid and cook on low for 6 to 8 hours. This slow cooking method ensures that the meatballs absorb all the rich flavors of the sauce while staying tender and moist.
- Thicken the Sauce: In the last 30 minutes of cooking, stir in the cornstarch slurry. This will thicken the sauce and give it a nice consistency to coat the meatballs.
How to Cook Beefy Onion Crockpot Meatballs: A Step-by-Step Guide
- Step 1: Mix your ground beef with the binding ingredients (breadcrumbs, eggs, and milk), as well as your seasonings like onion soup mix and garlic powder.
- Step 2: Form the meat into evenly sized balls. Browning is optional, but it adds more flavor and helps the meatballs hold their shape.
- Step 3: Prepare your sauce with beef broth, ketchup, Worcestershire sauce, onions, and a touch of brown sugar for sweetness.
- Step 4: Let the crockpot do its magic, slow-cooking the meatballs to tender perfection.
Common Mistakes to Avoid
- Overmixing the Meatball Mixture: Overworking the meat can result in tough meatballs. Combine the ingredients until just mixed.
- Skipping the Browning Step: While not essential, browning the meatballs adds extra flavor and helps keep them intact in the crockpot.
- Not Using Enough Liquid: Make sure the meatballs are covered in sauce to keep them moist during the slow cooking process.
- Undercooking: Ensure the meatballs cook for the full 6-8 hours to allow the flavors to meld together and the meat to fully cook.
Serving and Presentation Tips
To elevate the dish’s presentation and overall appeal, here are a few tips:
- Garnish: Sprinkle chopped fresh parsley or cilantro over the meatballs before serving. The bright green color contrasts beautifully with the rich sauce.
