Instructions

How to use this Recipe:

This recipe is written so that every element of the burgers can be made from scratch, using whole ingredients. The buns, burgers, aioli, and even the onions can all be made ahead to save time. Once prepped, this burger recipe takes less than 30-minutes to cook and assemble, less if you do not use a grill. I have provided an FAQ with a timeline to help with cooking order and timing, if you want to make everything at once. I have also added information about store-bought substitutions/options. Enjoy!

Homemade Brioche Buns

Making brioche buns requires about 90 minutes of prep, 25 hours for proofing, and 20 minutes for baking. If you make the buns more than a day ahead of time, immediately freeze them after they bake. They will stay fresh up to 2 months in the freezer, so you can defrost them at your convenience. I do not have a specific burger bun recipe written for the blog, but I do have a recipe that uses brioche dough (Classic Brioche Cinnamon Rolls). So, I suppose the burger bun recipe will live here for the time being. You can make between 8-10 buns from this recipe.
First, begin bringing your butter and eggs to room temperature about 30 minutes before you start in earnest. Next, whisk the milk and honey together and warm them, in a sauce pot on your stove. If you see steam, you've gone too far. Pour the milk and honey into your stand mixer’s bowl and use a thermometer to wait until the temperature has fallen between 110-115°F (43-46°C). Once you are in that window, add in the active dry yeast and let it rest for 10-15 minutes, so it can bloom.
While that’s working, measure out the flour and salt and set aside. Also, very lightly butter a large bowl for proofing the dough later.
When the yeast has bloomed, turn on the mixer with the whisk attachment and add in the eggs. Once incorporated, add in salt and then flour a little at a time until it's about the viscosity of pancake batter.
Switch out the whisk attachment for a dough hook and continue mixing in the flour until it comes away from the sides of the bowl; It may take upwards of 15 minutes. At this point you can begin to add the butter pieces one-at-a-time. Once one mixes into the dough fully, you can add the next until all of the butter has been added.
Continue mixing until the dough gets shiny and smooth and you can gently touch it without it immediately sticking to your fingers. It may need another 10 minutes of mixing to get to this stage. At any point, you can stop to do a windowpane test (see notes), to see if the dough is ready to proof. When it’s ready, scrape the dough into the lightly buttered bowl and cover with cling wrap.
Set it on the counter for 1-2 hours or until it doubles in size. Then, gently (so as not to deflate the rise thus far) place it in the fridge to chill for at least 2 hours. 24 hours is best if you have the time.
After cold proofing, remove the dough from the refrigerator and scrape it onto a generously floured counter. Coat the dough just enough that you can place it onto a kitchen scale. Weigh the dough for a total weight and divide by the number of burger buns you’d like. (9 equal pieces should be ≈ 122g per piece)
Shape the pieces of dough into small balls by pulling the bottom of the dough up and over towards the middle of the ball from all four corners. Then rotate it 45 degrees and fold from the bottom again. Turn the whole thing over making sure the folds stay tucked. Then, gently rotate and shape the dough finalizing your sphere and melting the seams, from the tucking, into the bottom of the spheres. Press gently down on the rounds of dough with your palm until they are about 3in (7.6cm) in diameter. Place the buns about 2in (5cm) from each other on a baking tray. Then, cover and rest the rolls on the countertop for 45-60 minutes for a second proof. They should puff up considerably.
While proofing, pre-heat the oven to 375°F (190°C) and make an egg wash for the rolls. Whisk a whole egg with 1 tablespoon (15ml) of water and a pinch of salt until it’s homogenized. Set the wash aside for at least 15 minutes. Just before the buns go into the oven, brush on the egg wash. Bake the brioche burger buns for 15-20 minutes. The internal temperature of the buns should reach 190°F (88°C).
Let the buns cool before cutting and toasting them for the cheeseburgers.

Homemade Burger Patty

I provided my preferred cuts of meat for the burger mix because I have a meat grinder attachment for my KitchenAid mixer, and once I started using it, I never looked back.
If you’d like to share in the magic that is fresh ground meat, buy these cuts and put them in the freezer when you get home from the store. When the meat is about half-frozen, chop the beef into 1in (2.5cm) cubes.
Attach the meat grinder tool to your mixer using the medium plate (coarse and fine aren’t good for this applications) and place a bowl underneath to catch the ground beef. Turn the grinder on and add meat to the chute. Tamp down on the pieces, to ensure they don’t get stuck. Once all of the meat has been run through the grinder, gently fold and mix the three varieties of beef together to make sure the mix is uniform to the eye. It can be helpful to make a claw with your hand and circle it around the bowl, kind of like washing rice. It helps mix without compression.
Next, weigh and shape the burgers. Each patty should be about .25lbs (113.5g) and 4.5in (11.4cm) in diameter. When shaping the patties, sandwich a weighed sphere of meat between both hands and press downward until you almost have the correct diameter. Then pinch and shape the edges of the patty, so there are no gaps or pieces that could break off while cooking. Set the burger down on a work surface and gently press the center of the burger down, so it goes gradually concave from edge to center, like a very shallow bowl. Place the finished burgers on a tray or plate. If you aren’t cooking them within 15 minutes, place the container in the refrigerator to wait. They don't need to be covered.

Homemade Aioli

This recipe takes 5 minutes, makes enough for 8-10 burgers, and lasts for roughly 2 weeks in the refrigerator.
For the aioli, add all of the ingredients a wide jar or cup and mix with an immersion blender for 1-2 minutes. It’s best to start at the bottom of the container and slowly lift the blender until the eggs and oil are all properly emulsified. Then, move the blender up and down until the mayonnaise forms into a thick paste the texture of soft peaked whipped cream. (If you don’t have a stick blender, see notes.)

Griddle onions

Find the top of the onion, opposite of the roots, and chop it off to create a flat surface. Set the onion down, root-side up and slice the onion in half. From there, lay the onion down with the center on your cutting surface. Cut off the rooted top of the onion and then, make vertical slices from left to right. Repeat with the other half and then the second onion.
Set the onion slices aside and bring a stainless-steel pan to medium-high heat on your stove top. Once hot, add in a pat of butter and the onions. Sprinkle a pinch of salt over the onions, while mixing, to help pull out their moisture. In roughly 5-7 minutes, the onions will start turning translucent. Continue for another 7-10 minutes and turn the heat down to medium heat if you see too much charring on the edges of the onions. Additionally, if the onions are sticking to the bottom of your pan or a fond (brown crust) starts to form on the bottom of the pan, deglaze it with a little bit of water. The water will help steam and cook the onions faster, incorporate the flavor from the fond, and give the onions their signature brown color.
Stop when the onions have softened considerably, but the centers of the larger pieces still look light in color. The onions should both be floppy but retain their structure enough to not be mushy. They will have just enough sweetness to balance the burger with a slight crunch to their texture still. Set the onions aside for assembly.

Gourmet Burger Assembly

If you plan to grill your burgers, prep your grill before you do anything else, so it has time to pre-heat. If you are cooking your gourmet griddled onion and brie burgers on your stovetop, preheating time isn’t really necessary.
To make a burger, gather the rolls, patties, griddled onions, aioli, arugula, and brie. Set the patties on a plate or pan and sprinkle them with kosher salt and cracked pepper on both sides. Let the patties rest at room temperature for between 15-30 minutes. Now, slice the buns in half and spread butter on the cut sides. To prep the cheese, slice the brie into thin strips (between 1/8-1/4in or .3-.6cm depending on how much you like brie) to top the burgers.
Burgers and buns on the grill: Now that your grill and burger ingredients are prepped, place the burgers, indent side up, on the grill and close the top. Let the burgers cook for 3 minutes and then open the grill lid. The center of the burgers should have juice accumulated there if they are ready to turn. Flip the burgers over and cook for another 3-5 minutes depending on your preferred doneness. In the last 1-2 minutes of cooking, top the burgers with the brie slices. Add the buns, butter side down, to the grill and toast them at this point as well. Remove everything from the grill when ready and assemble the burger.
Burgers and buns on the stovetop: Bring a stainless-steel pan to medium heat on your stove top and toast the buns, butter side down for 30-60 seconds. I like to do a single piece at a time, right in the center of the pan, but if you have the space feel free to toast more. When the buns are done, add 4 burger patties at a time to the pan. Cook them indent up until the centers have accumulated juice, about 4 minutes. Then, flip the burgers over to cook the other side. Cook the patties for another 3-5 minutes, adding the slices of brie in the last 2 minutes of cooking. When done, move the finished burger patties off of the pan and repeat until all of them have been cooked.
Now, you can build your burgers. Spread about 1tbsp (15ml) of aioli onto the bottom half of the bun. Then, add a nice helping of griddled onions. Top the onions with the melted cheese patty and cover that with a small bunch of arugula, topping the whole thing with the rest of the toasted bun. Enjoy!

Notes

Brioche:

If you forget to take the eggs out of the fridge before making the dough, you can add them to a large bowl of tepid water to warm up quickly.
To soften butter quickly, fill a glass jar with tap-hot water for a minute, pour it out, and then place the empty glass over the butter. The air temperature in the glass will help soften the butter without melting it. You can also, cut your butter into 1tbsp (14g) pats and arrange them on a plate with little overlap so they soften faster. More surface area means faster heat transfer between the butter and the ambient air around it.

Burger Patties:

If you don’t want to or you can’t grind your own beef patties, purchase burgers from your local supermarket. Look for ground beef with similar cuts of meat listed, i.e. ground chuck. Or look for the fattiest option available. Where I live, I believe, the best ratio is 75% lean, 25% fat.
When buying meat, make sure you consider the weight of the bones for the oxtail and possibly short ribs. For the oxtail, look for packaging that has the largest ratio of meat and fat to bone, with the fewest amount of smaller segments. You won't have to purchase as much.
To trim oxtail, use a boning knife if you have one (something thin). Remember the vertebrae alternate top and then bottom as you work around the spinal column.

Aioli:

If you don't have an immersion blender for the aioli, here are a few other options: 1. a regular blender; 2. a hand beater; 3. a stand mixer with whisk attachment; 4. a whisk; and 5. shake the ingredients in a lidded jar (yep, that’s an option!).
I have an easier version with storebought mayo in the FAQs.
