The Schlow Burger with Cheddar, Crispy Onions, and Horseradish Sauce

I really never thought I would be writing down this recipe, but everyone with an opinion and a say-so said, “You gotta put it in the book.” So here goes — try this burger once and see if it doesn’t make you change the way you order your burgers. Someday, maybe I’ll open a burger joint and feature this colossal, monster of a sandwich on the menu, but for now I’ll stick to making it in my own backyard.
NotesThe sauce can be made up to three days ahead; the onions can be prepared early on the day they will be served.

Ingredients
- 18 ounces ground beef (Ask the butcher for 80 percent lean. Do not change this part, please!)
- 1 ounce (2 tablespoons) extra-virgin olive oil
- Salt and pepper
- 4 tablespoons mayonnaise
- 2 teaspoons prepared white horseradish
- Juice of half a lemon
- 2 thick slices good quality Vermont or English cheddar cheese
- 2 hamburger buns, split in half (buy the best ones you can get; I like brioche buns)
- Crispy Onions (recipe follows)
- Fresh ground pepper
- 1 large yellow onion, sliced into very thin rings, 1/3- to 1/8-inch thick
- 2 cups canola oil
Instructions
-
Combine the ground beef with the olive oil, salt, and plenty of black pepper.
-
Divide the meat into two 9-ounce patties and refrigerate until the grill is ready. (Don’t do this more than an hour in advance.)
-
Combine mayonnaise, horseradish, and lemon juice in a mixing bowl and season with black pepper. (You can do this ahead of time and store it in the fridge.)
-
Heat the grill to high.
-
Take the hamburgers out of the refrigerator 5 to 7 minutes before you are ready to grill them.
-
Place the burgers on the preheated grill and cook 1½ minutes (for rare).
-
Give the burgers a quarter-turn to “mark” them, and cook 1½ more minutes.
-
Flip the burgers over and cook 1½ minutes.
-
Rotate a quarter-turn to “mark” and cook 1½ more minutes.
-
Transfer the burgers to the grill’s top shelf or to a cooler section of the grill and cover each one with a slice of cheese.
-
Turn the grill off and shut the lid.
-
After 4 minutes, open the lid. The cheese will be melted and the burgers cooked rare to medium rare. Toast the buns, if desired, and place a burger on each.
-
Spread plenty of the horseradish sauce on each burger; it should drip down the sides.
-
Top with Crispy Onions and season with freshly ground black pepper.
-
Slather more sauce on the other half of the bun and place it on top of the burger.
-
Grab a cold beer or iced tea and get ready to make a mess. This is not a dainty meal.
-
For the Crispy Onions:
-
Place onion rings and oil in a small sauce pot. (Don’t worry if the rings break apart; it won’t ruin the final product.)
-
Bring to a boil over high heat, and then reduce heat to a very low simmer. The heat releases the onion’s natural sugars, and in essence, causes them to melt.
-
Turn the onions with a fork every thirty seconds or so, and cook until they turn golden brown, 12 to 15 minutes. Adjust the heat if needed to maintain a low simmer.
-
Remove the onions from the oil and arrange in a single layer on paper towels. (At this point the onions won’t yet be crispy, but I promise you that after a few minutes, as the caramelized sugars cool and harden, the onions will become deliciously crisp.)

This is the definitive burger, in my opinion. I never change a thing about the recipe and it's absolutely mouth watering.
