1-First Step: Preheat and Prep the Muffin Tin Preheat oven to 400°F (200°C). Grease a 12-cup muffin tin generously with butter or oil. This step prevents sticking and promotes crisp bottoms on your baked parmesan potato stacks. Wipe excess to avoid pooling. For gluten-free ease, any muffin tin works fine.

2-Second Step: Slice the Potatoes Wash 4-5 medium Yukon Gold potatoes thoroughly. Slice to 1/8-inch thickness using a mandoline or sharp knife. Aim for even pieces to ensure all potato stacks cook uniformly. If adapting for low-carb diets, these slices fit perfectly. Pat dry to remove excess moisture for extra crispiness.

3-Third Step: Season the Slices In a large bowl, toss potato slices with 4 tablespoons melted butter, 1/2 cup grated Parmesan, 2 minced garlic cloves, 1 teaspoon thyme, salt, and pepper. Coat every slice thoroughly. For vegan versions, olive oil keeps it plant-based. This mixture creates the signature cheesy flavor in easy potato stacks parmesan.

4-Fourth Step: Stack in Muffin Cups Stack 5-6 seasoned slices into each muffin cup, fanning them slightly for pretty presentation. Press gently to compact. Sprinkle extra Parmesan on top. Repeat for 12 stacks. This method yields muffin tin parmesan potatoes that hold shape. Dietary note: Vegan stacks firm up similarly.

5-Fifth Step: Bake to Perfection Bake 45-55 minutes until tops turn golden brown and crispy. Edges should crisp while centers stay tender. Check at 45 minutes; rotate tin if needed for even browning. For busy schedules, this hands-off bake suits working professionals. Let cool 5 minutes in tin before removing with a spoon.

6-Final Step: Serve and Enjoy Gently scoop out stacks onto a platter. Garnish with fresh thyme if desired. Serve hot as a side for 6 people. Pairs well with roasts or salads. Total time: 1 hour. Pro tip: Press stacks during assembly for compact, restaurant-style shape. Troubleshoot sogginess by ensuring thin slices and full bake time.
