What’s in the Bowl
To create this mouthwatering Tennessee Onion Dip, you’ll need the following ingredients:
- 2 large chopped sweet onions (I used Vidalia for their distinct sweetness)
- 2 tablespoons unsalted butter
- 1 cup mayonnaise
- 4 ounces softened cream cheese
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- 2 teaspoons salt
- 1 cup shredded cheddar cheese
- 1 cup shredded smoked gouda cheese
- Chopped parsley for garnish
Cook’s Kit
Before diving into the cooking process, make sure you have the following kitchen tools:
- Large skillet – for sautéing the onions to perfection.
- Mixing bowl – to combine all the creamy goodness.
- Spatula – for stirring and mixing ingredients.
- Measuring cups and spoons – to ensure accurate ingredient amounts.
- Baking dish – a 9-inch pie dish or similar for baking the dip.
Stepwise Method: Tennessee Onion Dip

Step 1: Sauté the Onions
Start by heating the unsalted butter in a large skillet over medium heat. Add the chopped sweet onions and a pinch of salt. Sauté the onions, stirring occasionally, until they are soft and caramelized, about 15-20 minutes. The goal is to bring out their natural sweetness.
Step 2: Prepare the Creamy Base
In a mixing bowl, combine the softened cream cheese and mayonnaise. Use a spatula to mix until smooth. This will create a rich, creamy base for your dip.
Step 3: Add Flavorings and Cheese
To the creamy mixture, add the garlic powder, dried thyme, and salt. Stir well to combine. Then, fold in the shredded cheddar and smoked gouda cheeses until evenly distributed.
Step 4: Combine Everything
Once the onions have caramelized, let them cool for a minute. Then, fold the sautéed onions into the cheese mixture until everything is well combined.
Step 5: Bake the Dip
Preheat your oven to 350°F (175°C). Transfer the mixture to a baking dish and spread it evenly. Bake for 25-30 minutes, or until the dip is bubbly and golden on top.
Step 6: Garnish and Serve
Remove the dip from the oven and let it cool slightly. Garnish with chopped parsley for a pop of color and freshness. Serve warm with crackers, bread, or fresh vegetables.
Smart Substitutions

If you’re looking to customize this Tennessee Onion Dip, here are a few smart substitutions:
- For a lighter version, consider using Greek yogurt instead of mayonnaise.
- Swap out smoked gouda for regular gouda or even fontina for a different flavor profile.
- Fresh herbs can replace dried thyme – a tablespoon of fresh thyme will add brightness.
- For a kick, add a pinch of cayenne pepper or red pepper flakes to the cheese mixture.
What I Learned Testing
- Patience is key when caramelizing onions. Low and slow ensures maximum sweetness.
- Mixing the cream cheese and mayonnaise first creates a smoother dip.

- This dip is incredibly forgiving—feel free to adjust cheese types based on what you have on hand.

- Cool the dip completely before transferring it to an airtight container.
