Grilled Mac and Cheese

Grilled Mac and Cheese

Working along side USA Onions has been a fun adventure over the last 2 years.  I have been able to learn so much from them about onion types, growth, harvesting, sizing but most important, which onions work best when grilling. All of that knowledge is important, however grilling onions got me most excited. 

For instance, take this Mac and Cheese recipe from USA Onoins.  I love the idea but it was missing one important ingredient…a grill! So I translated the recipe for the grill because it brings way more flavor to the dish and makes the process way more fun.  Take a look at the tips and recipe below and get grilling!

Tips for grilling the onions:

  • Use a vegetable basket to grill the onions.
  • Preheat the basket on the grill for 10-15 minutes.
  • Use olive oil, salt and pepper to season the onions.
  • Grill the onions in the vegetable basket at 375-400 degrees direct heat for 15-20 minutes.
  • Grill the onions in two to three batches for maximum flavor.
  • After grilling the onions, let them cool before adding them to your Mac and Cheese.

How to bake on a grill:

  • Set your grill up for indirect heat placing the pan with the Mac and Cheese directly in the center of the grill grates.
  • For gas grills, turn the outside burners on medium heat and keep the center burner on off.
  • For charcoal grills, place 25 lit briquettes on each side of the kettle.

Tips:

  • Instead of heating up your house, use a side burner to boil the noodles.
  • The cheese sauce makes for a great dipping sauce. If you have extra, warm it up and use it as an appetizer at your next party at home. 

Hopefully you can use some of the tips above to get more flavor out of this delicious Mac and Cheese recipe, all while having fun in your own backyard.
