Stuffed Onion Slices on a Plank
This is a fantastic and easy recipe for stuffed onions on the grill. Instead of using a whole onion, they are sliced, placed on to a grilling plank, and topped with a delectable blue cheese filling. They make a great appetizer, side dish, and even served in burgers.
Servings: 6 People
- olive oil
- 2 large wood planks (cherry or red oak)
- salt and black pepper to taste
- For stuffed onions:
- 2 large sweet onions (peeled and sliced 1/2" thick)
- 1 cup blue cheese crumbles
- 1/3 cup walnuts (toasted and chopped)
- 1 1/2 teaspoons fresh thyme leaves
- 1/4 teaspoon black pepper
- Soak wood planks in tepid water for at least 30 minutes before using.
- Preheat grill for medium high heat.
- Toast walnuts in a skillet for 2-3 minutes. Make sure to move them around while in the pan, or else they run the risk of burning. Once they become fragrant, remove from heat and let cool for 2-3 minutes. Chop into smaller pieces and set aside.
- Peel and slice onions. Remove planks from water and dry off really well. Brush olive oil onto plank and carefully place onion slices on, about 3 slices per plank. Brush the tops of onion with oil and season with salt and black pepper.
- Combine blue cheese with chopped walnuts, thyme leaves, and black pepper. Cover and place mixture into refrigerator.
- Place planks with onion slices onto grill. Close lid and cook for 12-15 minutes. Reduce heat if needed. Onions should be almost tender and starting to brown around the edges.
- Scoop a little less than 1/4 cup of blue cheese filling onto each slice. I find it's easier to do this by hand, rather than using a spoon. Close lid to grill and continue cooking for 3 minutes. Remove from grill and serve.
