Baked French Onion Dip

This warm, savory, and cheesy baked dip captures all the rich flavors of classic French onion soup in a creamy, crowd-pleasing appetizer.

Ingredients

1 tablespoon unsalted butter or olive oil
2 medium yellow onions, roughly chopped (about 2 cups)
8 oz cream cheese, softened
1 cup sour cream
⅓ cup mayonnaise
1 cup shredded Swiss or Gruyère cheese, divided
½ teaspoon onion powder
½ teaspoon garlic powder
1 teaspoon Worcestershire sauce
½ teaspoon freshly ground black pepper
Kosher salt, to taste
Optional garnish: chopped fresh chives or parsley, extra shredded cheese

Instructions

1. Caramelize the Onions

In a skillet over medium-low heat, melt butter.
Add chopped onions and cook, stirring occasionally, until deeply golden brown and caramelized (about 25–30 minutes). Reduce heat if browning too quickly.
Let cool slightly, then roughly chop further if you prefer smaller pieces.

2. Preheat Oven & Prepare Baking Dish

Preheat oven to 375°F (190°C).
Lightly grease a small baking dish or 8-inch oven-safe skillet.

3. Mix the Dip

In a large bowl, beat softened cream cheese until smooth.
Add sour cream, mayonnaise, ¾ cup of the shredded Swiss/Gruyère, onion powder, garlic powder, Worcestershire sauce, black pepper, and a pinch of salt.
Fold in caramelized onions until well combined.

4. Bake

Spread mixture evenly into prepared baking dish.
Top with remaining ¼ cup shredded cheese.
Bake 20–25 minutes, until bubbly around edges and golden on top.

5. Serve

Let cool slightly (5 minutes).
Garnish with fresh herbs if desired.
Serve warm with sturdy chips, sliced baguette, crackers, or fresh vegetables.

📌 Tips for Success

Low and slow caramelization is key—don’t rush the onions for the deepest flavor.
For extra richness, use a mix of Gruyère and Swiss cheeses.
Make ahead: Prepare dip (through step 3) up to 1 day in advance; store covered in fridge. Let sit at room temperature 20 minutes before baking.
Storage: Refrigerate leftovers up to 4 days. Reheat in oven or microwave.
Variation: Add ½ teaspoon thyme or a splash of dry white wine to the onions while cooking.

This baked French onion dip is irresistibly creamy, warmly spiced, and packed with savory-sweet onion flavor—perfect for game day, holidays, or cozy nights in! 🧅🧀🔥
