Ingredients :

• 3 medium yellow onions, thinly sliced
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1/2 teaspoon kosher salt
• 1/4 teaspoon freshly ground black pepper
• 1 teaspoon sugar (optional, enhances caramelization)
• 1/2 cup mayonnaise
• 1/2 cup sour cream
• 1/2 teaspoon garlic powder
• 1 1/2 cups shredded Gruyère cheese
• 1/4 cup grated Parmesan cheese
• Optional: fresh thyme or chopped parsley for garnish

Directions :

• Heat butter and olive oil in a skillet over medium-low. Add sliced onions, salt, and pepper. Cook 30–40 minutes, stirring occasionally, until golden brown. Stir in sugar halfway if using.
• In a bowl, combine mayonnaise, sour cream, garlic powder, half the Gruyère, and all of the Parmesan. Stir in cooled caramelized onions.
• Preheat oven to 375°F (190°C). Transfer mixture to a baking dish, sprinkle with remaining Gruyère, and bake 20–25 minutes until bubbly and golden.
• Remove from oven, cool 5 minutes, garnish with fresh herbs, and serve warm with crostini, crackers, or sliced baguette.

how to serve Caramelized Onion and Gruyère Dip

Serve warm. Put the dip in a shallow baking dish so it stays hot and bubbly. Offer crostini, sliced baguette, crackers, or raw vegetables. Add fresh thyme or parsley on top for color.

how to store Caramelized Onion and Gruyère Dip

Cool to room temperature. Cover and store in the fridge for up to 3 days. Reheat in a 350°F (175°C) oven until warm, about 10–15 minutes. You can also reheat in a microwave in short bursts, stirring between each.

tips to make Caramelized Onion and Gruyère Dip

• Cook onions low and slow for the best sweetness and color.
• Stir occasionally but not too often; let onions brown before moving them.
• Use real Gruyère for the nutty, melty texture. Swiss can work in a pinch.
• Taste before baking and add a bit more salt or pepper if needed.
• Let the dip rest 5 minutes after baking so it firms slightly for easier scooping.

variation (if any)

• Add cooked crumbled bacon for a smoky touch.
• Stir in finely chopped roasted red pepper for color and tang.
• Use caramelized shallots instead of onions for a milder flavor.

FAQs

Q: Can I make the onions ahead of time?
A: Yes. Cook the onions up to 3 days ahead and keep them in the fridge. Mix and bake when ready.

Q: Can I make this dip without mayo?
A: You can use extra sour cream or cream cheese, but the texture will change slightly.

Q: Is there a non-dairy version?
A: For a dairy-free option, use plant-based mayo and a non-dairy cheese that melts well. The flavor will be different but still tasty.

Q: Can I freeze the dip?
A: You can freeze the baked dip, but the texture may change. Freeze in a sealed container for up to 1 month. Thaw in the fridge before reheating.
