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.

This was amazing! The flavours played with each other so well, and it was almost sad to see an empty plate at the end of it all. I love how simple it is to prep the onions ahead of time though; making this a simple weekend prep for a go-to weeknight meal!

Had to cook on a lower temp setting - burned the first sandwich! But yummy and easy - LOVE the brussels sprouts.

Very good! I added some roasted sweet potatoes too and my husband grilled the steak so it was extra good. The caramelized onions really put it over the top.

These sandwiches were delicious! I tried fig butter on one and strawberry jam on another. Both were tasty. My onion was pretty big, so next time, maybe less onion or more cheese.

I don't personally like onions but decided to give this a shot anyway. It was definitely not onion-y and I was pleasantly surprised. I think it'd be better with a more flavorful cheese (I used swiss).
