Ingredients List for Crockpot French Onion Meatballs

Before you get started, gather these simple ingredients. This recipe uses everyday items that you probably already have in your pantry and fridge.

For the Meatballs:

• Ground beef: 1 lb (450g) of ground beef. You can use 80/20 ground beef for a juicy, flavorful result. Ground turkey or pork also work if you prefer.
• Breadcrumbs: ½ cup (60g) of breadcrumbs, either plain or Italian-seasoned.
• Egg: 1 large egg, beaten. This helps bind the meatballs together.
• Onion powder: 1 teaspoon for added flavor in the meatballs.
• Garlic powder: ½ teaspoon for a bit of depth.
• Worcestershire sauce: 1 tablespoon for umami and richness.
• Salt and pepper: To taste. About ½ teaspoon of salt and ¼ teaspoon of pepper should work.
• Parsley: 2 tablespoons of chopped fresh parsley or 1 teaspoon dried, for added flavor and color.

For the French Onion Broth:

• Onions: 2 large yellow or sweet onions, thinly sliced. These will caramelize and give the dish its classic French onion flavor.
• Beef broth: 3 cups (720ml) of low-sodium beef broth to form the base of the sauce.
• Butter: 2 tablespoons of unsalted butter for sautéing the onions.
• Worcestershire sauce: 1 tablespoon to deepen the flavor of the broth.
• Thyme: 1 teaspoon of dried thyme or 1 tablespoon of fresh thyme leaves.
• Bay leaf: 1 bay leaf for an aromatic layer of flavor.
• Flour: 1 tablespoon of all-purpose flour to thicken the broth slightly.

For Topping:

• Gruyère cheese: 1 cup (100g) of shredded Gruyère cheese. Mozzarella or Swiss cheese also work well as a substitute.
• Fresh parsley: Chopped parsley for garnish (optional).

Substitutions and Variations

This Crockpot French Onion Meatballs recipe is versatile, and you can easily adjust it to suit your dietary preferences or available ingredients. Here are some ideas:

• Ground Meat Substitutes: Instead of ground beef, try ground turkey or chicken for a leaner option, or ground pork for added richness.
• Gluten-Free Version: Use gluten-free breadcrumbs and substitute flour with cornstarch to keep this recipe gluten-free. You could also serve the meatballs over gluten-free pasta or rice.
• Vegetarian Option: For a meat-free version, substitute the meatballs with plant-based meat alternatives or make mushroom-based vegetarian meatballs.
• Cheese Options: Gruyère is the classic cheese for French onion soup, but you can use Swiss cheese, mozzarella, or even cheddar for a different flavor profile.
• Spice it Up: Add a pinch of red pepper flakes or a splash of hot sauce for a spicy kick.

Step-by-Step Cooking Instructions

Let’s walk through the steps for making Crockpot French Onion Meatballs. While the slow cooker does most of the work, there’s a little prep required to ensure everything turns out perfectly.

Step 1: Prepare the Meatballs

1. In a large bowl, combine the ground beef, breadcrumbs, egg, onion powder, garlic powder, Worcestershire sauce, parsley, salt, and pepper. Mix everything together gently until just combined, being careful not to overmix as that can make the meatballs tough.
2. Roll the mixture into evenly-sized meatballs, about 1 to 1 ½ inches in diameter. You should get about 20-24 meatballs, depending on the size.

Step 2: Sear the Meatballs (Optional but Recommended)

• Heat a tablespoon of oil in a large skillet over medium heat. Working in batches, brown the meatballs on all sides for about 1-2 minutes per side. This step adds extra flavor and helps the meatballs hold their shape during cooking. Once browned, transfer the meatballs to the slow cooker.

Step 3: Caramelize the Onions

1. In the same skillet, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, for about 10-15 minutes until they are soft and golden brown. This step is key to achieving the deep, sweet flavor that mimics French onion soup.
2. Sprinkle the flour over the onions and stir to coat them evenly. Cook for another minute to get rid of the raw flour taste.

Step 4: Assemble the Crockpot

1. Transfer the caramelized onions to the slow cooker, spreading them evenly over the meatballs.
2. Pour in the beef broth, Worcestershire sauce, thyme, and add the bay leaf. Gently stir to combine.
3. Cover the slow cooker with the lid and cook on Low for 6-7 hours or High for 3-4 hours, until the meatballs are cooked through and tender.

Step 5: Add the Cheese

• About 15 minutes before serving, sprinkle the shredded Gruyère cheese (or your preferred cheese) over the meatballs. Cover the slow cooker and let the cheese melt into a bubbly, gooey topping.

How to Cook Crockpot French Onion Meatballs: A Step-by-Step Guide

1. Mix the Meatball Ingredients: Combine ground beef, breadcrumbs, egg, and seasonings.
2. Form and Brown the Meatballs: Shape the mixture into meatballs and sear them (optional).
3. Caramelize the Onions: Cook onions in butter until golden brown and sweet.
4. Assemble in the Crockpot: Layer meatballs, onions, broth, and seasonings in the slow cooker.
5. Slow Cook: Cook on Low for 6-7 hours or High for 3-4 hours.
6. Add Cheese: Top with cheese 15 minutes before serving to allow it to melt.

Common Mistakes to Avoid

To make sure your Crockpot French Onion Meatballs turn out perfectly, avoid these common mistakes:

• Not Caramelizing the Onions: Don’t rush this step! Caramelizing onions is what gives this dish its rich, sweet flavor. Be patient and cook the onions until they turn a deep golden-brown.
• Overmixing the Meatballs: When mixing the meatball ingredients, be gentle. Overmixing can lead to tough, dense meatballs.
• Skipping the Sear: While you can skip browning the meatballs, this step adds a lot of flavor and helps lock in moisture. It’s worth the extra effort!

Serving and Presentation Tips

When your Crockpot French Onion Meatballs are ready, it's time to think about how to serve and present them for the best effect.

• Serve Over Starches: These meatballs pair wonderfully with mashed potatoes, egg noodles, or even rice. The creamy, savory broth will soak into the starch, making for an irresistible combination.
• Crusty Bread: Serve with slices of crusty French bread to mimic the bread element of French onion soup. The bread can be used to soak up the rich broth.
• Add a Side Salad: Balance the rich, hearty flavors with a fresh, crisp side salad, such as a green salad with vinaigrette or a Caesar salad.

Crockpot French Onion Meatballs Recipe Tips

• Use Low-Sodium Broth: Since both the cheese and Worcestershire sauce are salty, use low-sodium beef broth to control the saltiness of the dish.
