Our roast tomato and sweet onion dip recipe was originally published in 2014 and re-published in 2022 with some updated photos. It’s an oldie but goodie! You’re lookin’ a hot mess or what we call our roast tomato sweet onion dip. And we’re not talking about emotional issues or drama. This cheese dip is so freaking good and the tomatoes add a nice balance to the rich cheese.

It was so hard to not face-plant into this dip when it was bubbly, drippy, hot and messy from the oven. When it comes to cheese dips, our friends are like beasts and un-tamed hungry animals waiting to lick every smear of our sweet onion dip. Our sweet onion dip, aka “Crack-dip”, has made it’s round quite a bit online. We first shared this recipe in 2008 but finally gave it a hero’s welcome in our Bountiful cookbook and re-shared the recipe again last year on this blog post. Since then, it was given new life and enjoyed again on party tables across America.

Adding Roasted Tomatoes to Cheesy Dip

This sweet onion dip is our popular original recipe. Now we added fresh cherry tomatoes on top! It’s was a totally random idea because our garden is giving off some seriously beautiful cherry tomatoes. So we thought it would be nice to have some roasted cherry tomatoes to eat with the dip and rather than roast them separately, we just plopped them on the dip and baked it all together. What resulted was a hot mess of delicious roasted tomatoes on top of the perfectly brown-crusted sweet onion dip.  The tangy roasted tomatoes add a nice balance to the richness of the cheesy dip.

Can you make this dip ahead of time?

Sure, you can make it ahead of time. This is a great make-ahead party dip. You can save time and within an hour your dip will be party-perfect.

  • Mix together all the dip ingredients and lay the cherry tomatoes on top. Store it in the fridge up to 4 days before baking.
  • When you plan on baking it, take it out of the fridge and allow the dip to come to room temperature. This allows the dip to bake all the way through the center.
  • If you put a very cold dip (and vessel) in the oven, the top will burn before the center of the dip cooks.
  • Serve with grilled bread, chops or your favorite crackers. For a low carb/keto version, serve with cucumber slices and other chopped vegetables.

This dip is to die for and you can bet this hot mess will make an appearance at every single gathering we have this Summer, or at least until we run out of cherry tomatoes. Hey, maybe we’ll re-name this dip to “The Hot Mess” and if we were to couple it with the “Crack Dip”, it could be the “Hot Mess Crack Dip”. Yeah? Ok. Let’s dive in.

  • 8 ounces (225g) cherry tomatoes , depending on baking dish you use & how many tomatoes you need to cover the dip
  • 8 ounces (225-g) cream cheese (at room temperature)
  • 1 cup (100g) freshly grated Parmesan
  • 1 cup (240ml) mayo (preferably Best Foods brand)
  • 1 medium sweet onion , diced (about 1 and 1/2 cups)
  • 2 teaspoons freshly cracked black pepper


  • Preheat the oven to 350°F (175°C).
  • In a bowl, mix together the cream cheese, mayonnaise, Parmesan, onion, and black pepper and until everything is thoroughly combined.
  • Spread the cheese mixture into a 6-inch (15-cm) baking dish or any oven-safe dish. Lay cherry tomatoes across the dip.
  • Bake for about 50 minutes to one hour, until the tomatoes are roasted and the cheese is bubbly hot and brown. We like to bake it further to get a really brown crust on the dip.
  • Serve with your favorite crackers, crusty bread or crunchy vegetables such as radishes, jicama, carrots, and celery. To make it gluten free or paleo, don’t serve it with bread. Instead, just serve it with the crunchy vegetables or gluten free bread.
