Ingredients List: Everything You’ll Need

Meatball Ingredients

These ingredients create the juicy, flavorful base of the dish:

1½ lbs ground beef (80/20 blend recommended)
½ cup breadcrumbs (Italian-style or plain)
1 egg (for binding)
2 tablespoons milk (adds moisture)
1 tablespoon Worcestershire sauce
1 teaspoon garlic powder
1 teaspoon onion powder
½ teaspoon salt
½ teaspoon black pepper
1 tablespoon chopped parsley (optional for freshness)

French Onion Sauce Ingredients

For that iconic taste, you’ll need:

2 large yellow onions, sliced thin
2 tablespoons butter
1 tablespoon olive oil
2 cups beef broth (low-sodium preferred)
1 tablespoon Worcestershire sauce
1 teaspoon dried thyme
1 bay leaf
1½ cups shredded Gruyère or Swiss cheese (optional topping)

Step-by-Step Cooking Instructions

The process is easy to follow. Each step builds layers of flavor and texture.

1. Prepare the Meatball Mixture

Start by mixing your meatball ingredients in a bowl. Follow these simple tips:

Use a fork or your hands to combine the meat gently.
Don’t overwork the mixture—it keeps the meatballs tender.
If the mixture feels too wet, add more breadcrumbs.

Tips for success:

Make meatballs uniform in size (1½ inches).
Refrigerate for 15 minutes if the mix feels sticky.
Optional: sear them briefly for added depth.

2. Caramelize the Onions

This is the heart of the flavor. Here’s how:

Heat butter and olive oil in a skillet.
Add onions and a pinch of salt.
Cook low and slow—stir frequently for 20 minutes.

What to look for:

Onions should be golden brown and soft.
Deglaze with a splash of beef broth to pick up flavor from the pan.

3. Assemble in the Crock Pot

Layering everything properly makes a difference:

Place caramelized onions at the base.
Pour in beef broth, Worcestershire, thyme, and bay leaf.
Gently place the meatballs on top.

4. Slow Cook to Perfection

Set your slow cooker:

Low for 5–6 hours
High for 2½–3 hours

Resist opening the lid too often—heat loss slows cooking.

5. Add Cheese and Serve

In the last 15 minutes:

Sprinkle cheese over the top.
Let it melt into a gooey, irresistible topping.

Plate and garnish with fresh parsley or green onions for a pop of color.
