Hamburgers With Mustard Butter Recipes

Steps:

• Build a charcoal fire or heat a gas grill.
• Place the ground beef in a large bowl and add the mustard, olive oil, salt, and pepper. Mix gently with a fork to combine, taking care not to compress the ingredients. Shape the meat into 6 (3 1/2-inch) patties of equal size and thickness.
• When the grill is medium-hot, brush the grill grate with oil to keep the burgers from sticking. Place the burgers on the grill and cook for 4 minutes. Using a big spatula, turn the burgers and cook for another 3 to 4 minutes, until medium-rare or more, or cook longer if you prefer hamburgers more well done.
• Meanwhile, break apart the English muffins and toast the 6 halves cut side down on the grill. Spread each half with mayonnaise and top with a burger and then with a heaping tablespoon of caramelized onions. Serve hot.
• Heat the olive oil and butter in a large shallow pot, add the onions and thyme, and toss with the oil. Place the lid on top and cook over medium-low heat for about 10 minutes to sweat the onions. Remove the lid and continue to cook over medium-low heat, stirring occasionally, for 25 to 30 minutes, until the onions are caramelized and golden brown. If the onions are cooking too fast, lower the heat. Add the vinegar, salt, and pepper and cook for 2 more minutes, scraping the brown bits from the pan. Season to taste (they should be very highly seasoned).

Steps:

• Heat grill to high. In a medium bowl, use a fork to gently combine beef, mustard, and Worcestershire sauce; season with salt and pepper. Gently form mixture into four 1-inch-thick patties.
• Place patties on hottest part of grill; sear until browned, 1 to 2 minutes per side. Move patties to cooler part of grill; continue grilling until desired doneness, 4 to 8 minutes per side.
• Split the hamburger buns and toast on the grill if you like; place a burger on each bun and serve with the desired accompaniments.

Steps:

• Combine butter and mustard until smooth. Chill until semifirm. Toss together tomatoes and onion.
• Start a charcoal grill. Divide the beef and mustard butter into 4 four equal portions. Press butter into the center of each piece of beef and form a ball around it. Gently flatten into a patty. Grill to desired doneness.
• Place a lettuce leaf on the bottom half of each bun and top with a patty. Season the meat with the salt and pepper. Top with the tomato mixture and bun tops. Serve immediately.
