French Onion Sliders for #SundaySupper

It’s that time of the year! I’m bringing these fabulous French Onion Sliders to the Red Carpet party todays Sunday Supper theme. Pretty designer dresses, interviews, and amazing awards are being talked about this weekend as we gear up for the 87th Annual Academy Awards or better known as the Oscars tonight! Don’t you just love a good Red Carpet Party? Thanks so much to Katie of Ruffles & Truffles for hosting this smashing party. It’s time to gather good friends, drool worthy food and break open the wine to see who will win what awards tonight. I am a huge movie buff. If it’s a new release of a comedy, action packed, drama filled or even a good thriller kind of movie, you can bet I’ve seen it. I like to laugh at the dresses that some people wear. I’m not big on “designer” wears, what’s in and what’s out and though some of these dresses are gorgeous beyond belief, there are plenty that are just giggle worthy to me! However it’s fun to watch actors and actresses win awards for all of the hard work they do, lets face it, acting is no easy job!

So what are we going to eat during this fine event of awards, dresses and performances? We have plenty to share with you! I decided to take a favorite soup of mine and turn it into a cute little slider! It was a big hit in my house!

This soup turned mini sandwich will be the hit to any party. Caramelized onions combined with melted provolone cheese will leave you coming back for more!
Cuisine: Appetizer
Serves: 12
  • 4 large yellow onions, sliced
  • 1 large yellow onion, minced
  • ½ stick of butter
  • 2 tbsp. of butter
  • 1 tsp. of sugar
  • Salt
  • 2 tbsp. of olive oil
  • 3 tbs. of Dijon Mustard
  • 2 tsp. of Worcestershire Sauce
  • 1 pkg. of slider buns or Hawaiian rolls (I used 12 small slider buns)
  • 6-8 slices of provolone cheese
  1. Preheat oven to 350F.
  2. Heat the olive oil and butter over medium hight heat until the mixture shimmers.
  3. Add the onion and coat them thoroughly and spread the mixture out evenly in the pan. Depending on your stove you may need to turn it down to medium to prevent the onions from burning.
  4. Let the onions cook for 10 minutes and then sprinkle the sugar and salt on top.
  5. Cook onions for another 20 minutes stirring throughout but not too much, you want them to slowly brown. If they get to dry add a little more oil. Continue cooking and scraping until they turn a good shade of brown.
  6. While the onions are caramelizing in a smaller pan melt the ½ a stick of butter over medium heat swirling it around. Once it's almost melted add the minced onions.
  7. Coat the onions with the butter and then add the dijon mustard and Worcestershire sauce.
  8. Mix to combine the flavors and cook for 5 minutes or until the onions are done. Set aside.
  9. Line a 13x9 baking dish with tinfoil. Cut the sliders in half (it's easy if they are combined, just slice right down the middle) add the bottoms to the baking dish.
  10. Spread the caramelized onions on top of the slider bottoms.
  11. Place the cheese on top overlapping if needed.
  12. Place the slider tops on top of the cheese.
  13. Using a spoon scoop some of the minced onion mixture on the top of each slider.
  14. Bake for 20 minutes or until the cheese is melted.
