Tennessee Onion Dip Recipe

Introduction

Tennessee Onion Dip is a rich and comforting appetizer perfect for any gathering. Featuring sweet caramelized onions and a blend of creamy cheeses, this dip bakes to golden bubbly perfection and pairs wonderfully with crackers or bread.

A round black skillet holds a thick, golden-brown baked cheese dip with a bubbly, slightly crispy top layer sprinkled with finely chopped green herbs. Underneath the cheesy surface are chunks of soft cooked onions mixed within the creamy dip, which is slightly scooped out on one side, showing its smooth, textured inside with toasted pieces of bread partially dipped in it. Around the skillet, several toasted slices of light golden-brown bread are placed on a white marbled surface, some leaning against the pan. The overall look is warm and inviting, with a mix of melted cheese, soft onions, and crunchy toasts. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 large sweet onions, chopped (Vidalia recommended)
2 tablespoons unsalted butter
1 cup mayonnaise
4 ounces softened cream cheese
1 teaspoon garlic powder
1 teaspoon dried thyme
½ teaspoon salt
1 cup shredded cheddar cheese
1 cup shredded smoked gouda cheese
Chopped parsley (for garnish)

Instructions

Step 1: Preheat your oven to 375°F (190°C). In a large oven-safe skillet, melt the butter over medium heat. Add the chopped sweet onions and cook, stirring occasionally, until they become soft and tender, about 15 minutes.
Step 2: Remove the skillet from heat. Stir in the mayonnaise, softened cream cheese, garlic powder, dried thyme, salt, shredded cheddar cheese, and shredded smoked gouda until well combined.
Step 3: Transfer the skillet to the preheated oven and bake for 25 minutes or until the dip is bubbly and lightly browned on top.
Step 4: Remove from the oven, garnish with chopped parsley, and serve warm with crackers, crostini, or your favorite bread.

Tips & Variations

For a smoky kick, add a pinch of smoked paprika or substitute smoked gouda with smoked mozzarella.
If you prefer a milder onion flavor, use sweet white onions or reduce cooking time slightly.
Make sure the cream cheese is softened to ensure a smooth, creamy texture in the dip.
You can prepare the onion mixture ahead and refrigerate before baking for convenience.

Storage

Store any leftover dip in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through, stirring occasionally to maintain creaminess.
