Prep

  1. Onions / Brussels sprouts - (If prepping right before cooking, get oven heating before continuing with prep.) Prep as directed. Larger brussels sprouts should be quartered. Store separately. (Can be done up to 5 days ahead)
  2. Caramelize onions - Heat up a frying pan over medium heat. Add oil (portion for sandwiches) and then add onions to heated oil. Saute for ~10 minutes, until tender but still crunchy. If it looks like the onions or pan will burn at any point, just add a splash of water. Stir in with vinegar and brown sugar (portions for sandwiches). Cook for another 2 minutes. (Can be done up to 5 days ahead)

Make

  1. Heat oven to 500F / 260C.
  2. Spread brussels sprouts out onto a sheet pan. Cover tightly with foil and then bake for ~6 minutes.
  3. Remove foil and toss brussels sprouts with oil, vinegar (portions for brussels sprouts), and mustard. Roast for another 8 to 10 minutes until crispy. Toss with brown sugar (portion for brussels sprouts) and salt, seasoning with more to taste.
  4. While brussels sprouts roast, butter one side of each piece of bread. Lay out bread, buttered-side down. Layer with jam, onions, cheese and top with bread, buttered-side up. Continue until all sandwiches are assembled.
  5. Heat up a griddle or a skillet over medium heat. Place sandwiches onto heated surface (as many as can fit) and press down throughout the grilling process with a spatula. Flip once the first side is golden, ~ 3 to 4 minutes.
  6. Enjoy sandwiches with brussels sprouts on the side.

Very tasty! I was a little skeptical at first, but after seeing a lot of rave reviews, I decided to give it a go. I used strawberry infused balsamic vinegar, so I omitted all the brown sugar from the recipe since the vinegar itself was sweet. Even my picky husband liked it

Excellent! Never would have thought that jam, onions and cheese would be good in a sandwich. Kudos to cooksmart! Need to increase the amount of sauce for the sprouts.

I really liked this, but next time I will leave out the brown sugar in both the onions and brussel sprouts. It was way too sweet for me, but I liked everything else about it.

This was so good! Chose to go without the jam on the sandwich, went without the brown sugar on the brussel sprouts, and forgot to add the balsamic and brown sugar to the onions. It was still delicious! Definitely recommend if anyone's looking to use a little less sugar!
