Ingredients You’ll Need
The best recipes don’t need to be complicated. Here’s all you need for this savory, golden-baked dip:
- 4 cups thinly sliced sweet onions (like Vidalia or any mild variety)
- 1 cup mayonnaise
- 1 cup shredded sharp cheddar cheese
- ½ cup grated Parmesan cheese
- ½ teaspoon garlic powder
- Salt and pepper to taste
These everyday ingredients combine beautifully to create a dip that’s creamy, tangy, and rich with flavor.

Step-by-Step: How to Make Tennessee Onion Dip
Follow these steps to create a cheesy dip that’s golden, bubbly, and packed with flavor:
1. Preheat Your Oven
Start by preheating your oven to 375°F (190°C). Grease a medium-sized baking dish or oven-safe skillet with non-stick spray or a light coat of oil.
2. Combine All Ingredients
In a large bowl, mix together the thinly sliced onions, mayonnaise, cheddar cheese, Parmesan cheese, garlic powder, salt, and pepper. Stir until everything is evenly combined and well-coated.
3. Transfer to Baking Dish
Transfer the mixture to your baking dish and smooth it into an even layer. For a little extra indulgence, you can top it with a handful of extra shredded cheddar.
4. Bake Until Golden
Bake uncovered for 25 to 30 minutes, or until the top is golden brown and the edges are bubbling. The onions will soften and slightly caramelize, blending perfectly with the melted cheese.
5. Serve Warm
Let the dip cool slightly before serving. Serve it warm, straight from the oven, for the best flavor and texture.
What to Serve with Onion Dip
This dip pairs well with a wide range of dippers. Here are some tasty options:
- Crackers – Buttery, crunchy, or whole grain.
- Toasted baguette slices – Adds crisp texture and rustic charm.
- Tortilla chips or pita chips – Perfect for scooping every last bit.
- Fresh vegetables – Carrots, celery, bell pepper strips, or cucumber for a lighter pairing.
Whether you’re hosting or snacking solo, this dip makes a satisfying centerpiece.
Tips for the Best Flavor and Texture
- Use sweet onions: Vidalia onions or any mild yellow onion work great.
- Slice onions thin: Thin slices blend and bake more evenly into the dip.
- Grate your own cheese: Pre-shredded cheese contains anti-caking agents that don’t melt as well. Freshly grated sharp cheddar melts beautifully and adds bold flavor.
- Let it rest briefly after baking: This allows the dip to set slightly and makes scooping easier.
Variations to Try
Want to add your own spin to this classic dip? Try one of these easy variations:
- Add green onions or scallions: For a slightly sharper bite.
- for softened cream cheese to make the dip extra rich and creamy.
- Go spicy: Add a dash of cayenne pepper, red pepper flakes, or diced jalapeños.
- Make it lighter: Use light mayo or a mayo-Greek yogurt blend to cut calories.
It’s easy to customize and still keep that delicious balance of sweet, savory, and creamy.
Storage and Reheating
This dip stores well and tastes just as good the next day.
- To Store: Let leftovers cool and place in an airtight container. Refrigerate for up to 3 days.
- To Reheat: Warm in the oven at 350°F until heated through, or microwave in 30-second bursts. Add a splash of milk or cream if needed to loosen the texture.
Perfect for Every Occasion
From casual nights in to festive gatherings, this dip fits the mood every time:
- Family movie nights
- Game-day snacking
- Holiday parties
- Birthdays or potlucks
- Or just a comforting weekend treat
It’s the kind of recipe that brings people together—and gets eaten fast.
