Gruyere and Egg Burgers

Rating: 4 out of 5.

  • Total Time Prep: 30 min.
  • Cook: 20 min.
  • Makes 8 servings


  • 1/2 cup mayonnaise
  • 2 garlic cloves, minced
  • 1 teaspoon lemon juice
  • 1/2 teaspoon grated lemon zest


  • 2 pounds lean ground beef (90% lean)
  • 1 tablespoon stone-ground mustard
  • 1 tablespoon olive oil
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 8 slices Gruyere or aged Swiss cheese
  • 8 mini pretzel buns, split


  • 2 tablespoons butter
  • 8 large eggs


  • Fresh arugula
  • 2 medium tomatoes, sliced
  • Additional stone-ground mustard, optional


  • Whisk mayonnaise, garlic, lemon juice and lemon zest until blended. Refrigerate.
  • For burgers, combine the next six ingredients, mixing lightly but thoroughly (do not overmix). Shape into eight patties. Grill, covered, over medium direct heat until a thermometer reads 160°, 5-7 minutes on each side. Top with cheese; grill, covered, until cheese is melted, 1-2 minutes longer. Place burgers on bun bottoms. Keep warm.
  • Melt 1 tablespoon butter over medium heat in each of two large skillets (on grill or stovetop). Break eggs, one at a time, into a custard cup or saucer, then gently slide into pans. Immediately reduce heat to low. To prepare eggs sunny-side up, cover pan and cook until yolks thicken but are not hard. To make basted eggs, spoon butter in pan over eggs while cooking. For over-easy, carefully turn eggs to cook both sides but do not cover pan.
  • To serve, spread mayonnaise mixture over bun tops. Add arugula, tomatoes and, if desired, additional mustard to burgers. Top with fried eggs. Replace bun tops.

Test Kitchen tips: Want big burgers? Just make 4 patties instead of 8; you can cut the eggs down to 4 as well. For extra springy flavor, mix fresh dill fronds into the burger patties instead of thyme. For a healthier alternative, use ground turkey in place of ground beef.
