Picnics are so much fun. At least it is when the weather cooperates. I haven’t been on one in far too long. The last time I can recall is when we had our boat many years ago. I would pack a basket and a cooler to take on our day trips to the lake. We always invited friends to join us for fun on the water. After a full morning of water skiing, tubing, and swimming we would stop, drop anchor, and enjoy a picnic lunch.
Water sports can build up a big appetite. I made sure to pack plenty so everyone would get their fill. After lunch we would relax and enjoy sunning while the boat was gently rocking in the water. Once we were re-energized it would be an afternoon of more skiing and boating. Back then the sandwiches were not “fancy”. They were a bun or roll with turkey or ham and some cheese. Fast forward to today and what I would choose for a picnic is a caramelized onion, goat cheese, and tomato sandwich.
A ciabatta roll is my choice for this sandwich. You could use a loaf and slice it. I used a splash of balsamic vinegar at the end of cooking the onions because it goes so well with tomato. A creamy goat cheese is a perfect spread. A fresh-picked, ripe tomato is the best choice. Heirloom tomatoes would be even better. Wrap the sandwiches in parchment and bring plenty of napkins. The onions will to try to escape and drip all over. The sandwiches are messy, sweet, tangy, savory chewy, and oh so good. Perhaps pack brownies for dessert.
When was the last time you went on a picnic? It’s the time of year to get out and enjoy nature. Goodbye cold weather and hello summer! Would you like some more recipes for dining outdoors? Scroll down to see what the talented Sunday Supper bloggers are sharing for our event.

Caramelized Onion, Goat Cheese, and Tomato Sandwich
Ingredients
For the caramelized onions:
- 3 large onions cut in half and sliced
- 2 tablespoons olive oil
- 1 tablespoon unsalted butter
- 1/2 teaspoon sugar
- Salt and fresh ground pepper
- 1 tablespoon balsamic vinegar
For the sandwiches:
- 4 ciabatta rolls about 4 inches wide
- 5 ounces creamy goat cheese
- 1 tomato sliced
Instructions
For the caramelized onions:
-
Heat the olive oil and butter in a wide sauté pan over medium-high heat until the butter melts and the oil shimmers. Add the onions and toss to coat with oil/butter.
-
Spread the onions out evenly in the pan and cook, stirring occasionaly, about 10 minutes. Lower the heat to medium or medium-low if the onions are browning too quickly. You do not want them to burn.
-
Sprinkle the onions with the sugar, salt, and pepper. Stir and continue to cook an additional 30 mintues to one hour, until the onions are evenly browned and caramelized.
-
While the onions are cooking, stir occasionally and add very small amount of oil or water if the onions look too dry or about to burn.
-
Once the onions are evenly brown and caramelized, add the balsamic vinegar to deglaze the pan. Be sure to scrape up the browned bits on the pan. Cook for an additional 1 to 2 minutes.
For the sandwiches:
-
Slice the rolls in half. Spread goat cheese on the bottom half. Top with caramelized onions and a tomato slice. Cover with top half of roll.

I agree – water sports, or just…laying on the beach…works up a big appetite! Must be all that sun or something! I would eat this sandwich on the beach in a heartbeat. And those tomatoes actually look pretty decent for this time of year!

They were good tomatoes for store-bought. I can’t wait for the fresh local ones to be ready.

Those tomatoes look absolutely luscious! Our garden tomatoes definitely aren’t ready yet, and the ones I’m getting from the store still don’t even compare! This is making me crave a perfectly ripe, juicy tomato! I love how simple flavors can be so wonderful when everything is in season.
Nancy @ gottagetbaked says
Renee, I wish you still had your boat – I’d come and visit you in a heartbeat. I’d also expect an amazing day like the one you described in this post – that sounds like so much fun! A delicious sandwich like this one is the perfect meal for resting in-between water sports (although I’d have to swap the goat cheese for another type…curse me for not liking goat cheese!). And yes to the brownie too, please 🙂
Katie says
Oh my goodness oh my goodness…the components of this sandwich are to die for! You had me at goat cheese alone…but with caramelized onions? Heaven.
Jennie @themessybakerblog says
I could easily scarf down two of these sammies. Yummo!
Anita at Hungry Couple says
My mother used to caramelize onions and then put them on bread for me as a snack. I’d forgotten about it till I read your post but I used to just love those. And, as an adult, goat cheese makes me happy, too.
Renee says
You were lucky to have that as a snack. I didn’t discover caramelized onions until a few years ago.
