What do roasted grapes taste like?

Roasted grapes are flavorful and more robust than fresh grapes typically. The roasting process breaks the skin of the grapes and the inside turns to an almost jam-like consistency. The flavor is juicy and sweet, which makes it a perfect compatible ingredient for pairing with savory spices like rosemary and goat cheese!

Fun facts about Grapes from California

Did you know that 99% of grapes grown in the United States are grown in California? 

  • They have been grown for over 200 years in two regions: the Coachella Valley and the San Joaquin Valley.
  • Grapes from California are in season May-January.
  • There are 80 different varieties and California grapes come in three colors – green, red, and black – in both seeded and seedless options.
  • There are approximately 340 table grape operations in California.

And, what’s great is that all colors of grapes – red, green, and black – are a natural source of antioxidants and other polyphenols, which contribute to heart health.

And most importantly, grapes can absolutely be part of a blood sugar friendly diet or eating pattern. If you want to read more about how I use California grapes and why it’s ok and encouraged for people with diabetes to eat grapes, check out this recipe and blog post!

Additionally, we know people with diabetes should eat a diet that promotes a healthy heart, so it’s great that California grapes are a heart healthy food and may help maintain a healthy heart! Adding grapes to the diet every day helps support heart health in both men and women.

While many factors affect heart disease, diets low in saturated fat, cholesterol, and sodium may reduce heart disease risk; and grapes are also a good source of vitamin K which promotes heart health. Grapes also support heart health by helping to maintain healthy circulation.

How to roast grapes

So, how do you roast grapes? There’s many different ways to approach roasting grapes, but they all result in a delicious end product! I prefer to bake at a higher temperature of 400 degrees F for about 15-20 minutes, though you can roast them for shorter or longer depending on the flavor or texture you want. 

You can also toss them in flavorings or oils, add nuts or seeds to the mixture, and more.

Crostini with roasted grapes recipe

You can use any variety of California seedless grapes for this recipe. To start, we’ll prep our grapes. Toss the grapes, walnuts, and balsamic glaze together in a bowl until fully coated. Then, we’re going to spread the grape and walnut mixture in a greased baking dish into one even layer and bake/roast them for about 15-20 minutes until the grapes start to wrinkle and caramelize.

Once we’ve roasted our grapes and walnuts, we just add those onto some sourdough bread and goat cheese, sprinkle with our seasonings and pop them back in the oven for a bit to toast up! And, that’s it!
