  • 8 russet potatoes, peeled and sliced into fry shapes (matchsticks)
  • 2 tbs. cooking oil with a high smoke point, such as grapeseed
  • 2 tbs. minced garlic
  • 2 tbs. fresh minced thyme leaves
  • 1 tsp. salt
  • 1 tsp. black pepper

Garlicky Feta Sauce:

  • 1/2 cup feta cheese
  • 1/4 cup full-fat Greek yogurt
  • 1 tsp. minced garlic
  • 1/2 tsp. lemon juice
  • 1/4 tsp. salt
  • 1/4 tsp. black pepper
  • 1/4 tsp. red pepper flakes
  • 1/8 tsp. oregano
  • 1/8 tsp. ground coriander

Sauteed Onion:

  • 1 large yellow onion, chopped
  • 1 tbs. cooking oil

Lamb Burgers:

  • 1 lb. ground lamb
  • 2 tsp. minced garlic
  • 2 tsp. minced fresh flat-leaf parsley leaves
  • 2 tsp. minced fresh thyme leaves
  • 2 tsp. minced fresh tarragon leaves
  • 1/2 tsp. salt
  • 1/2 tsp. black pepper
  • Cooking oil in pan as needed
  • 4 hamburger buns
  • 1 large tomato, sliced


  1. Preheat oven to 400 degrees. Toss potato sticks with the oil, garlic, thyme, salt, and pepper. Spread out on a baking sheet and bake until crispy, about 35 to 40 minutes (flipping fries halfway through to ensure even cooking).

  2. Prepare the feta sauce by adding all of its ingredients to a food processor or blender and processing until smooth. Refrigerate until burgers are ready to assemble.

  3. Sauté the onion by adding it with the oil to a pan over medium heat. Cook, stirring frequently, until softened and browned, about 10 to 12 minutes.

  4. Mix the ground lamb meat with the garlic, parsley, thyme, tarragon, salt, and pepper. Form into four equally-sized patties. Swirl cooking oil around a frying pan; add the burgers and cook over medium-high heat to your desired doneness, flipping halfway through the cooking process. Reduce heat and/or add more oil to the pan as needed. Five minutes of cooking on each side should yield a medium (pink in the center) burger.

  5. Nestle each lamb burger in a hamburger bun, topping it with feta sauce, a tomato slice, and sauteed onion. Serve with the fries - and savor the delicious results of your hard work!
