Ok, I know I say this every year, but how is it that summers are sooo incredibly busy?! Despite the extra sunlight, it just seems like there aren’t enough hours in the day!  The house is a disaster. The fridge is a barren wasteland.  The laundry overflow-eth.  Cue our new favorite summer recipe: Grilled Parmesan Garlic Tomatoes!

Ingredients Needed

a bowl of tomatoes.

Fresh tomatoes – This summer we grew some beautiful San Marzano tomatoes which are perfect for this recipe.
Fresh Garlic – Don’t let my recipe tell you how much to use, you measure that with your heart!
Parmesan cheese – This is one of our favorites to use, but you could also use Romano, Asiago, Mozzarella, or a mixture of any of them!
Olive Oil – Or your other favorite neutral-flavored oil.
Seasonings: Onion powder, Garlic powder (because is there ever too much garlic?), Rosemary, Salt, and Pepper. See recipe notes for using fresh vs. dried.

Best Tomatoes to Use

Our favorites for this recipe are Plum Tomatoes (also known as Paste Tomatoes or Romas). This is because they have low moisture, fewer seeds, and denser flesh which means you can just slice them in half and toss them on the grill and they’ll hold up to the heat.

The best varieties to use:

  • San Marzano
  • Amish Paste
  • Viva Italia
  • Big Mama
  • Golden Mama

Avoid using: 

  • Beefsteak
  • Cherokee Purple Tomato 
  • Brandy Sweet Plum

Basically, stay away from big and juicy tomatoes. While perfect for many other recipes, they won’t work for this one.

    i just LOVE tomato season and am so excited about it! It’s the only time of year i really eat tomatoes. these look incredible – great idea to make them on the grill!

    1. They’re one of the best! I also like romas for this recipe too – just make sure they’re not too ripe otherwise they’ll fall apart on the grill. Enjoy!

    They look fantastic, such great flavours… We have a dozen San Marzano tomato plants in the garden so I’ll be keeping this recipe until they start to bare fruit ๐Ÿ™‚
