Here are the Main Ingredients you will Need:

Step-by-Step Instructions:

Preheat to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.

Cook potatoes- Place potatoes in an air fryer and spray lightly with cooking oil. Sprinkle them with salt and pepper. Bake in the air fryer at 400 degrees for approximately 15 minutes until fork tender.

While the potatoes are cooking, In a large skillet over medium heat, brown ground beef and onion. When halfway cooked, add finely diced zucchini.

Stir in garlic powder, 2 ½ tsp smoked paprika, salt, and pepper. Continue cooking until beef is fully browned and zucchini is tender.

Drain excess fat, then remove from heat and let cool slightly.

In a medium bowl, whisk together Greek yogurt, light mayo, mustard, ketchup, relish, pickle juice, and 1 tsp smoked paprika. Reserve 3–4 tbsp of this sauce in a small bowl for topping after baking.

Pour the remaining sauce over the beef mixture and stir until creamy and evenly coated. Fold in half of the pickles and combine.

Place the baked baby potatoes in the casserole dish and use the bottom of a cup to gently smash them into an even layer, forming the potato base. Add the sauced beef mixture over the potato layer. Sprinkle shredded cheddar evenly over top.

Bake covered with tinfoil for 8–10 minutes, until hot and cheese is melted.

Remove tinfoil and broil for 1–2 minutes until bubbly and golden.

Let cool for 5 minutes.

Top with remaining diced pickles, shredded lettuce, and the reserved sauce. Garnish with sesame seeds for that “Big Mac” touch.

Recipe Notes & Modifications

• Pickle Preference: For extra crunch, reserve all the pickles for topping instead of mixing half in.
• Fridge: Store in an airtight container for up to 4 days.
• Reheat: Warm in the oven or microwave; add fresh lettuce after reheating.
