I really wanted to make an out-of-this-world burger and I’m pretty sure I succeeded! I didn’t want to make it too over the top, with a bunch of insane flavors, so I put together some classics and knocked it out of the park!

I had a friend coming over for our usual dinner, movie and catch up night last week and I wanted to make something yummy for us. We don’t see each other often enough, so I made it special. It’s funny that you can live practically next door to someone and only see each other a couple of times a month. Adulthood is just too busy! I wish that I could be a kid again so I had no worries and play with my friends all day. If I could go back to being a kid again, I would be the best kid a parent could ask for! I’d take naps (many naps), eat all the food put in front of me (hello, it’s food appearing in front of you!), and do all my chores because it’s the easiest way I’ve ever earned money.

Anyway, I went off topic again, back to this fabulous burger

This was actually my first experience with making buffalo burgers and I loved it! Paiting it with smooth, creamy Monterrey Jack cheese and caramelized onions was perfect. Pretzel bun was a last minute decision as I was walking through the bakery section of the store but it turned out to be a great choice. Now the Demi Glace…oh boy! This is like a “cherry” on a beautiful burger sundae. This is an easier recipe for the sauce and it takes much less time. I will have to share a true recipe for Demi Glace some time but for today, we will stick to this one. You can also prepare it ahead of time and just refrigerate it until ready to use.

I hope you will enjoy this burger and let me know how much!

You can make caramelized onions and Demi Glace at the same time to save time. If you have the stove-top space, cook burgers, sauce and onions at the same time, just note that burgers take the least amount of time.
Serves: 1 cup of Demi Glace / 2 burgers
  • Easy Red Wine Demi Glace:
  • 2 cups of beef stock (veal stock of you can find it)
  • 1 cup of red wine
  • 2 medium, chopped shallots
  • 2 tsp thyme
  • Fresh cracked peppercorns
  • 1 bay leaf
  • Roux = 2 Tbsp soft butter + 2 Tbsp flour
  • Burgers:
  • 1 lb ground buffalo meat
  • ⅓ cup minced yellow onion
  • ¼ cup bread crumbs
  • salt, pepper
  • Caramelized Onions:
  • 1 medium yellow onion, sliced
  • 2 Tbsp olive oil
  • salt
  • pinch of sugar
  • __
  • Pretzel rolls
  • Monterrey Jack Cheese
  1. Easy Red Wine Demi Glace:
  2. In a small pot, combine stock and red wine, bring to boil over medium-high heat. Lower the heat to medium and add sliced shallots, bay leaf, thyme, salt and peppercorns. Simmer for 45-55 minutes until reduced in a little more than half, stirring occasionally. Stir soft butter and flour into paste and add it to the sauce. Slowly stir until thickened. Set aside.
  3. Caramelized Onions:
  4. Preheat frying pan with olive oil on medium heat. Add sliced onions and sprinkle with a little bit of sugar and some salt. Stir well. Cook slowly (medium to medium-low heat), stirring often, as the onions caramelize to nice brown color. Set aside when done.
  5. Burgers:
  6. Mix buffalo meat, onion, bread crumbs, salt and pepper until all evenly combined. Divide into two patties and cook over medium heat until reached desired temperature.
  7. Add slices of Monterrey Jack cheese on top to let the cheese melt.
  8. Assemble burgers by spreading some Demi Glace on the bottom bun and adding burger patties with cheese, caramelized onions and some more sauce on top.
