Balsamic Portobello & Swiss Chard Panini

A hot sammy on a chilly fall day sounds just about right. These Portobello mushroom and Swiss chard paninis are Eric’s and my go-to weeknight dinner. Typically, Eric is all about the meat. Dinner equals meat or else he’s a hungry man! But these paninis are meatless, yet meat is not missed!

For all the vegetarians out there (or those striving to cut down on their meat intake!), these paninis make it easy to be meat-free.

Makes: 3 large paninis

Prep time: 15 minutes

Cook time: 10 minutes

Total time: 25 minutes

The Ingredients

6 ounces Portobello mushrooms, sliced

1 medium bunch Swiss chard, chopped (including stems)

1 small red onion, sliced

1 large garlic clove, thinly sliced

6 slices Swiss cheese

2 1/2 tablespoons good-quality balsamic vinegar

1 tablespoon extra-virgin olive oil, plus more to drizzle on bread

6 slices bread of choice (I like rye Tuscan pane! I also like wheat.)

1/2 teaspoon herbes de Provence (or substitute with thyme, rosemary and/or Italian seasoning blend)

Salt and pepper




The Steps

For Portobello and Swiss chard sauté: In a large skillet over medium-high heat, sauté olive oil, balsamic, Portobello slices, Swiss chard, red onion, garlic, herbes de Provence, salt and pepper for 5-7 minutes until onions just start to soften and Swiss chard just wilts. Remove from heat.

For sandwich assembly: Assemble each sandwich by taking 2 slices of bread and drizzling them with olive oil. Add a generous amount of the Portobello mixture to one slice of bread, using a slotted spoon. Place 1-2 slices of Swiss on top of the mixture, and then place the other slice of bread on top. Grill sandwich in a panini press for 4-5 minutes until the sandwich has nice grill marks.

TIP: if you don’t have a panini press, place sandwich in a large skillet over high heat. Place a cast iron skillet on top of the sandwich to press it down. Toast each side for about 3 minutes until golden.

Slice and serve hot.
