Caramelised Onion Dip

onion dip and pretzel bites from side

Making a caramelised onion dip recipe has been on my “to-create” list for a while now. This dip is very more-ish and an excellent addition to any cocktail or dinner party spread. This dip has never lasted very long whenever I made it for a party. People just love it!

One thing I learned over the last couple of years working as a chef is that onions are incredibly versatile. And caramelising onions until they’re soft, sweet and golden is probably my favourite way to cook them. Adding the caramelised onions to creamy, blended cashews and fragrant rosemary makes this dip irresistible.

Not sure what to serve the caramelised onion dip with? 🤔

Of course, raw vegetables such as carrot and cucumber sticks go really well, BUT the ultimate most delicious thing to dip into this caramelised onion dip are Pretzel Bites. A match made in heaven!

I hope you love this recipe as much as I do. Please don’t forget to tag me in your creations on Instagram @nothangryanymore. I love seeing them!
