Crispy Zucchini Stacks
Ingredients
Cooking spray
2 large zucchini, sliced into 1/8″ coins, divided
Kosher salt
3 cloves garlic, grated or finely chopped
1/2 c. whole milk
1 Tbsp. chopped fresh thyme or 1 tsp. dried thyme
1 Tbsp. Dijon mustard
1/2 tsp. freshly ground black pepper
1 1/2 oz. Parmesan, shredded (about 1/2 c.), divided
1 1/2 oz. Gruyère, shredded (about 1/2 c.), divided
1/3 c. panko bread crumbs
1 Tbsp. extra-virgin olive oil
Marinara sauce, for serving


Directions
Preheat oven to 425°. Spray a standard 12-cup muffin tin with cooking spray. Arrange one-third of zucchini on a paper towel-lined baking sheet; season with a pinch of salt. Repeat with remaining zucchini, separating each layer with paper towels. Let sit 10 minutes.
Meanwhile, in a large bowl, whisk garlic, milk, thyme, mustard, and pepper. Stir in half of Parmesan and half of Gruyère. Add zucchini and toss to coat.
Layer zucchini slices in prepared muffin cups, evenly dividing slices among cups. Pour remaining cheese mixture in bowl over stacks. Bake 20 minutes.
Meanwhile, in a small bowl, combine bread crumbs, oil, and remaining Parmesan and Gruyère. Top zucchini stacks with bread crumb mixture. Continue to bake until topping is golden brown and crispy, 20 to 25 minutes. Let cool 5 minutes before serving.
