FAQ’s

Can I make this recipe the day before?
YES! Just prepare it up until the instructions tell you to bake it. Cover with a lid or plastic wrap and let sit in your fridge overnight.
Can I use greek yogurt instead of sour cream?
Yes! Go for it; I just prefer the taste of the sour cream in this recipe.
Do I need to use the alcohol in this recipe?
Certainly not, just remove it from the recipe all together or add 2 tbsp of beef broth instead.
Can I serve this dip cold?
You sure can! I would recommend slicing the onions into smaller pieces if you decide to serve this one cold.

French Onion Dip

By Sammy Montgoms
French Onion Dip: imagine sinking a piece of bread into the rich, sweet flavours of brown sugar caramelized onions with a creamy base that includes cream cheese, sour cream, and loads of shredded cheese.
Prep: 15 minutes
Cook: 45 minutes
Servings: 10 people

Ingredients 

  • 2 tbsp olive oil, extra virgin
  • 2 tbsp butter
  • 5 yellow onions, sliced thin
  • 3 tbsp brandy or cognac
  • 2 tsp balsamic vinegar
  • tbsp brown sugar
  • 1 block cream cheese (250 grams), room temperature
  • cups sour cream
  • 1/3 cup mayonnaise
  • cups gruyère, shredded
  • 1 cup mozzarella, shredded
  • 1/2 tsp dried thyme
  • 1/4 tsp garlic powder
  • 1/4 tsp black pepper, to the cream cheese mixture
  • salt

Instructions 

  • Begin by peeling and slicing the onions.
  • To a large non stick pan set to low heat, add the olive oil and butter.
  • Add the sliced onions and begin cooking on low heat for 30-40 minutes, stirring often.
    Sammy's tip: be sure to cook the onions on low heat to avoid them from burning. If you notice the onions have little moisture left and appear to be burning, reduce the heat and deglaze with a tsp or so of water.
  • After the onions have been cooking for about 20 minutes deglaze the pan with the brandy and season with salt and pepper.
  • Allow the brandy to reduce, about 2 minutes.
  • Add the balsamic vinegar and brown sugar and let simmer until the brown sugar has melted and the onions are coated.
  • Once the onions are a deeply golden, thick, and have a jam-like consistency, with most of the liquid evaporated, remove from the heat and set aside until ready to use.
  • To a large mixing bowl combine the cream cheese, sour cream, and mayonnaise.
  • Using a hand blender or large wooden spoon, mix to combine until you reach a smooth creamy consistency.
  • Add the gruyère, mozzarella, dried thyme, garlic powder, black pepper and caramelized onions and gently mix to combine.
    Taste to see if you want to add any salt.
  • Pour into a large baking dish, cover, and bake in a 375 °F oven for 25-30 minutes, or until bubbling.
  • Serve with bread, tortilla chips, or fresh veggies.
  • Enjoy warm.

    This was the hit of the party! I made it in the morning and then sprinkled some Gruyรจre on top and baked it before the party. So delicious and goes with veggies and chips. Thank you for an amazing recipe that I will be making on repeat.

  2. Hi there- this recipe looks incredible!! I want to make it for Xmas eve

    Question : do you think I can make ahead, wrap up and refrigerate and then bake a few hours later?

  3. 5 stars
    I made this for Thanksgiving and it was fantastic! Such a crowd pleaser!

    Iโ€™d love to make it again but my kiddo is allergic to eggs and canโ€™t have the mayo. What substitute would you recommend?

  4. Hi! Hoping to make this for Christmas Eve! Wondering if I can cook it in a crockpot instead of baking it in the oven? Or, could I bake it then transfer to a crockpot to keep warm? Thank you!

    1. Hi Maria! You can totally pop this into a crockpot after assembling! Just keep it on low and allow it to cook for about an hour or 2. Just until it’s warm throughout, and slightly bubbly. I hope you enjoy – Sammy

    If I could give this 10 stars I would. I made this for our friends holiday party and my god, no one could step away, it was that good. I’m making this again for an xmas day app!
