Hands up if you’ve ever been served a disappointing vegetarian panini?

I find that the packaged bread sold as panini bread in the UK and the US can be rather bland, so if you don’t cram it full of intensely tasty filling, the overall effect will just be blandness. And for some reason, it seems a common mistake to put as much filling into a panini as you would a regular sandwich, which is not enough.

This does not apply in Italy, where the bread is totally different and every panino is absolute perfection. Oh, Italy. Always winning at food.I set out to make the perfect vegetarian cheese panini filling and this is the result!

When dealing with our reality of packaged panini bread, when it comes to fillings, we just need more, more, more.

It can be an easier thing for meat eaters with their salami or bacon, because those things pack a lot of taste into a small package and can be mixed with cheese to double up on flavor. But for vegetarians, we need our cheese and vegetables to work a lot harder.

So here is my offering. Bread? Coated in dijon mustard. Cheese? Smoked. Onions? Caramelized.

Result? A rich filling which is nicely offset by the thick, crispy bread, without being drowned out. Just try drowning out this crazy, gooey mix of All Things Umami.

By the way- isn’t it weird that we say “panini” when we refer to a singular, when it’s actually the Italian pluralized version of “panino”? Why can’t we say “panino” too? That’s a way cooler word.

If your panini is not messy- you aren’t doing it right. There is nothing more disappointing than a well contained panini, a sure sign that you’ve skimped on filling. The panini in these photos? I don’t even know what’s going on.

There is going to be melted cheese and stray bits of onion dripping out the sides, and you may stare quizzically at it for a few moments, wondering what your best move is going to be.

This is not your average cheese panini!

Smoky Cheese & Caramelized Onion Panini

Yield: 2 panini
Prep Time: 50 minutes
Cook Time: 5 minutes
Total Time: 55 minutes

I set out to make the perfect vegetarian cheese panini filling and this is the result! Packed with flavor and lots of melty, smoky, cheesy filling, it's a panini recipe that everyone can enjoy.

Ingredients

  • 2 panini bread
  • 2 red onions, thinly sliced
  • 1 tblsp of butter
  • 1/2 Tbsp of mayonnaise or butter
  • 2 tsp of dijon mustard
  • 75g (2.6oz) smoked cheddar cheese , grated
  • 75g (2.6oz) fresh mozzarella, thinly sliced

Instructions

  1. First, caramelize the onions. On a very low heat- the lowest your hob can manage- melt the butter into a pan and stir in the onions. Leave for around 30 minutes to 1 hour (It really depends on how low your heat can go- the lower the heat, the slower they will cook. You want it as slow as possible for a good flavor and texture.)
  2. Slice the paninis, and spread with mayo and mustard.
  3. Add the fillings in this order: 2/3rds of the smoked cheddar, mozzarella, red onions, remaining 1/3rd of the smoked cheddar.
  4. Seal panini and press in a grill or frying pan until the cheese is melted. You can brush the outsides with oil to get extra crispiness but it's not required.

Notes

I used paninis from Costco. They're a bit smaller than the usual ones you get in cafes. I'm not sure whether they are the same as the ones in the US or Canadian Costcos. In any case, you may wish to scale up the ingredients if you think your paninis are a little bigger.
